  • Private participation not at the cost of ISRO’s capabilities: Staff in fresh note

    Why in the News

    A group of employee associations of the Indian Space Research Organisation (ISRO) has asserted in a fresh statement that private participation in the space sector must not weaken the agency’s own capabilities. The four page note, issued by a Joint Action Council (JAC) of the associations and circulated among ISRO staff, states that technologies and facilities developed by the agency must not be transferred to private parties at “throwaway prices”. It follows a September 4 letter to the ISRO Chairman, sent a day after the successful launch of the GSLV-F17 mission, which sought clarifications on the agency’s future role. The Chairman had responded that there was no move to privatise the agency. The disagreement is over the boundary, not the principle: the associations accept private participation while demanding that the full capability chain for the agency’s launch vehicles stay in house.

    What does the Joint Action Council note demand?

    1. A return on public investment: The note states that ISRO’s capabilities have been built on public money and cannot become a source of private profit without an adequate return to the nation.
    2. No transfer at throwaway prices: It states that public wealth cannot be transferred at throwaway prices or treated as a freebie for private entities.
    3. Conditions on the transfer process: It demands a level playing field, transparency and accountability in how technology developed with public money is passed on.

    What prompted the associations to write?

    1. The September 4 letter: The associations first flagged their concerns in a letter to the ISRO Chairman on September 4, a day after the successful GSLV-F17 launch.
    2. The reports behind the concern: The letter responded to reports that the agency was being readied to focus its energies only on a few strategic missions, while ceding the rest of the space sector to private companies.
    3. The Chairman’s response: The Chairman stated there was no move to privatise the agency, and that it would continue to build and strengthen capabilities as it partners with the private sector to expand the space economy.
    4. The follow up engagement: He later addressed ISRO employees in a video conference to allay the concerns raised.

    Where does the note accept private participation?

    1. Not opposed in principle: The note states plainly that the associations are not opposed to private participation in the space sector.
    2. Who has a role: It names Indian industry, Public Sector Units and startups as having an important role in expanding India’s space ecosystem.
    3. The launch rate argument: It accepts a legitimate need to increase the number of mission launches, and that this cannot be achieved without private players.
    4. The stated limit: Accepting private players does not mean that mature technologies developed by ISRO are all transferred to outside entities.

    Which capabilities does the note want ring fenced?

    1. Two launch vehicles named: The note names the LVM3, ISRO’s heaviest operational launch vehicle, and the under development Next Generation Launch Vehicle (NGLV).
    2. The complete chain: It states that ISRO must retain the complete chain of capability, from research and development to realisation, integration, testing and launch.
    3. Why the chain matters: Retaining every stage rather than only design keeps the ability to build and fly a vehicle inside the agency, which is what the associations treat as core function rather than transferable technology.

    Challenges to private participation in India’s space sector

    1. Valuing publicly funded technology: There is no settled method for pricing a technology whose development cost was borne entirely by the exchequer, which is the precise objection the note raises. Eg. Technology transfer agreements for launch vehicle systems have been signed without a published valuation basis.
      The Fix: Publish a standard valuation and royalty framework for transferred space technology, so each agreement is measured against a stated method.
    2. A single customer market: Demand for Indian launch and satellite services is dominated by government programmes, so private entrants depend on public orders rather than on a commercial market. Eg. Indian small satellite launch startups have relied substantially on government and institutional payloads for early missions.
      The Fix: Commit multi year anchor procurement volumes in advance, so private capacity is built against a visible order book.
    3. Regulatory clearance timelines: Authorisation for launches, spectrum and frequency coordination and ground station approvals involve multiple agencies, which lengthens project cycles for private firms. Eg. Satellite communications operators have waited through extended spectrum allocation decisions before beginning commercial service in India.
      The Fix: Fix statutory outer limits for each authorisation stage under the single window mechanism, with deemed clearance on expiry.
    4. Loss of institutional skill: Transferring production of mature systems moves the engineers who build them out of the agency, which erodes the capability the agency is asked to retain. Eg. The note’s own demand covers realisation, integration and testing, not only design.
      The Fix: Tie every technology transfer to a retained in house production line for the same system, so the skill is duplicated rather than handed over.
    5. Liability for damage: India is liable under international space law for damage caused by objects launched from its territory, including those of private operators. Eg. The Liability Convention of 1972 places responsibility on the launching State rather than on the private entity.
      The Fix: Make insurance cover and indemnity terms a condition of authorisation, scaled to the mission’s risk class.

    Conclusion

    The dispute has narrowed from whether the agency is being privatised to where the boundary of its core function lies. The employee associations have accepted private participation and the launch rate argument behind it, and have drawn the line at the complete capability chain for the LVM3 and the NGLV. The Chairman’s assurance answers the question of intent but not the question of pricing, which is what the note actually asks. What to watch is whether a stated valuation basis accompanies the next transfer of an ISRO developed system.

    Back2Basics: Next Generation Launch Vehicle (NGLV)

    1. What it is: A heavy lift launch vehicle under development by ISRO, intended to succeed the current generation of operational vehicles.
    2. Approval: Its development was approved by the Union Cabinet in September 2024, with an outlay of about Rs 8,240 crore.
    3. Capability: It is designed to place roughly 30 tonnes into low Earth orbit, around three times the LVM3’s capacity, with a partially reusable first stage.
    4. Purpose: It is intended to support the Bharatiya Antariksh Station and India’s stated goal of a crewed lunar landing by 2040.

  • Chandrayaan-1 may have just detected oldest impact basin on Moon: Researchers

    Chandrayaan-1 may have just detected oldest impact basin on Moon: Researchers

    Why in the News

    Planetary scientists at the Physical Research Laboratory (PRL), Ahmedabad, have confirmed the existence of a hidden lunar impact basin, the Australe Basin, using mineralogical data gathered by Chandrayaan 1. This is the first time a concealed impact basin has been confirmed from mineralogy, and the basin had remained untraced because erosion along its rims defeats modern imaging techniques. The study, published in The Planetary Science Journal, places the basin along the southeastern hemisphere of the Moon and finds it could predate the South Pole Aitken Basin, the largest and oldest basin known. The tension is that the oldest impact record on the Moon is precisely the record surface topography has erased, so the ordering of lunar history now rests on a method that reads composition instead of shape.

    What is the Australe Basin?

    1. Australe Basin: It is a large lunar impact basin located along the southeastern hemisphere of the Moon, formed by a violent space impact such as an asteroid or meteorite strike.
    2. Why it stayed hidden: Its rims have suffered erosion, which removed the distinct outer rim that imaging techniques rely on to identify a basin.
    3. Its signature: It carries distinct morphology and gravity signatures together with an unusual mineralogical composition.
    4. Its volcanic province: It sits in a province characterised by 248 small basalt ponds arranged in a circular pattern, unlike previously known basins classified by their smooth and vast hardened lava surfaces.

    How did mineralogy find a basin that imaging could not?

    1. Moon Mineralogy Mapper: The mineralogy was detected using data from this National Aeronautics and Space Administration (NASA) imaging spectrometer, designed to build a mineralogical map of the lunar surface and operating between 405 and 3000 nanometres.
    2. The payload context: It was one of 11 scientific payloads on Chandrayaan 1, of which six were contributions from international space agencies including NASA and the European Space Agency (ESA).
    3. The method: Scientists studied the absorption bands exhibited by key lunar minerals, namely pyroxenes, olivine and plagioclase, which identify composition where topography carries no usable signal.
    4. What the composition showed: The basalts within the basin are relatively lower in calcium and higher in magnesium than the majority of lunar basalts, which are high in calcium bearing minerals.

    Why does the age claim matter, and how much of the Moon is still unmapped?

    1. The benchmark: The South Pole Aitken Basin is the largest and oldest known basin on the Moon, formed over 4 billion years ago.
    2. The claim: PRL scientists hold that the Australe Basin could be older than the South Pole Aitken Basin, which would move the earliest dated event in the lunar impact record.
    3. The detection deficit: Roughly 300 impact basins are believed to exist on the Moon and only 74 have been detected so far, so most of the lunar impact record remains unidentified.
    4. Why the eroded ones are the old ones: Basins with distinct outer rims are the ones imaging finds, so a detection method keyed to rims systematically misses the most degraded features.

    What does the finding mean for future lunar missions?

    1. The landing site link: The Chandrayaan 3 landing site, now known as Shiv Shakti point and located roughly 350 km away, also carries higher concentrations of magnesium, possibly material originally from the South Pole Aitken Basin transported there.
    2. Material spread to the south pole: Magnesium bearing lithologies are widespread across the Australe region, and since the region lies close to the lunar south polar region, material excavated by the impact is likely to have been deposited across the south pole.
    3. Reading a landing site in context: The study provides a framework to interpret data from landing missions in a broader geological context, by studying the regions that could have contributed material to those sites.
    4. The missions it serves: The mineralogical picture bears on NASA’s proposed Moon Base mission and on Chandrayaan 4, India’s lunar sample return mission, since such sites become targets for sample return.

    Challenges to lunar impact basin research

    1. Remote sensing cannot date a surface: Spectrometry identifies composition but assigns no absolute age, so an ordering claim rests on inference until a sample is dated in a laboratory. Eg. The age of the Australe Basin relative to the South Pole Aitken Basin is stated as the research team’s opinion rather than as a measured date.
      The Fix: Target the province for a sample return so radiometric dating can settle the sequence.
    2. Space weathering degrades the spectral signal: Continuous micrometeorite bombardment and solar wind alter the optical properties of the lunar surface, which mutes the absorption bands a spectrometer reads. Eg. The basin’s own rims were eroded past the point where imaging could detect them.
      The Fix: Calibrate orbital spectra against returned samples of known composition so the weathering offset is corrected rather than estimated.
    3. Coverage gaps at the poles: The lunar south polar region sits in extreme illumination conditions, so instruments that depend on reflected sunlight return poor data exactly where interest is concentrated. Eg. Permanently shadowed craters near the south pole are the targets of the proposed Moon Base and remain the least characterised terrain.
      The Fix: Pair reflectance mapping with active instruments such as radar and neutron spectrometry that do not depend on solar illumination.
    4. Sample return is technically unproven for India: Retrieving lunar material requires ascent from the surface, rendezvous in lunar orbit and a controlled return, none of which India has yet demonstrated together. Eg. Chandrayaan 4 is planned as India’s first lunar sample return mission.
      The Fix: Validate the docking and ascent elements separately in Earth orbit before committing them to a lunar sequence.
    5. Surface operations disturb the record they study: Landings and rover activity churn the regolith that later missions are sent to sample, which compromises the evidence itself. Eg. Understanding how the regolith in the south polar regions has evolved over billions of years is stated as a requirement for the missions planned there.
      The Fix: Fix exclusion zones around high value sampling terrain before the operating missions arrive rather than after.

    Conclusion

    A basin no imaging technique could see was found by asking what the surface is made of instead of what it looks like. That reverses the usual order of lunar geology, where shape identifies a feature and composition then explains it, and it puts the most degraded parts of the record back within reach. The finding is published and the age ordering remains an interpretation rather than a measurement. What to watch is whether the same mineralogical method is turned on the basins that remain undetected, and whether this province becomes a named target for the planned sample return.

    Back2Basics: Chandrayaan 1

    1. What it was: It was India’s first lunar mission, launched by the Indian Space Research Organisation in October 2008 and placed in orbit around the Moon.
    2. Launch vehicle: It was launched on a Polar Satellite Launch Vehicle from the Satish Dhawan Space Centre, Sriharikota.
    3. Its payloads: It carried 11 scientific instruments, six of them contributed by international space agencies including NASA and ESA.
    4. Its principal finding: Data from the mission led to the detection of water and hydroxyl molecules on the lunar surface, which reshaped the understanding of lunar resources.

  • For ISRO, expanding ecosystem is way forward

    For ISRO, expanding ecosystem is way forward

    Why in the News

    The chairman of the Indian National Space Promotion and Authorisation Centre (IN-SPACe), the nodal agency that promotes and guides private participation in space, has said that the Indian Space Research Organisation (ISRO) would eventually not manufacture any launch vehicles, and that the work would be done by private companies. The remark widened a dispute that had begun when ISRO tightened its norms for resignation and voluntary retirement of senior scientific personnel. Employee associations wrote to the ISRO leadership asking whether the remark represented official policy. The ISRO chairman then stated categorically that there was no move to privatise the agency. The same statement welcomed an increasing role for private companies. The contest is between an agency being restructured towards exploration and science, and the commercial launch revenue it would give up to get there.

    What triggered the dispute inside ISRO?

    1. The starting point was a personnel rule: ISRO tightened its norms for resignation and voluntary retirement of senior scientific personnel, which is what opened the wider debate.
    2. The dispute then changed subject: It expanded into questions about the role of the private sector in space and about the future of the space agency itself.
    3. The staff sought a policy ruling: Employee associations asked the leadership whether a public remark by the head of the promotion agency represented official policy, which the ISRO chairman answered by ruling out privatisation.

    What model is the government moving towards?

    1. The reference model is NASA: ISRO is being prepared to focus primarily on big-ticket space projects, scientific missions and exploration missions, with routine launches passing to private industry.
    2. The agency is also the mentor: ISRO is being asked to handhold private industry and help it reach a level of maturity.
    3. Personnel already move that way: Most private space companies carry retired ISRO scientists as advisors or mentors.
    4. Infrastructure is already shared: ISRO offers its launch pads and related services to these companies.
    5. A launch vehicle has already left the agency: ISRO developed the Small Satellite Launch Vehicle (SSLV) over the years and has transferred the technology to Hindustan Aeronautics Limited, a public-sector undertaking.

    What does an expanded ecosystem deliver?

    1. Launch volume and revenue: A private space ecosystem can carry a large number of commercial launches and bring in much-needed revenue.
    2. People and jobs: It can develop a large talent pool and generate fresh employment opportunities.
    3. Diplomatic weight: Capabilities in space products and services are becoming a powerful diplomatic good.

    Where does the model cut against ISRO?

    1. Provider or beneficiary: The concern within sections of the ISRO staff is that the agency should not merely be a provider to the ecosystem but also a beneficiary of it.
    2. The revenue it steps away from: By moving out of commercial launches, ISRO forgoes an important source of income it currently earns.
    3. Budget dependence constrains ambition: Becoming entirely dependent on government budgets limits capability, since neither research and development nor ambitious exploration projects are cheap.
    4. Talent has a price: An agency doing frontier work has to attract and retain top-tier talent, which is also what the tightened exit norms were reaching for.

    Why is institutional independence part of the argument?

    1. Political attention has helped: Sustained interest at the highest political level in the space sector has brought ISRO steady government support for its plans and projects.
    2. The success has a stated cause: ISRO’s record is often attributed to its relative immunity from government interference.
    3. The staff concern is about that autonomy: The apprehension within the agency is that a restructuring driven from outside erodes the independence the agency has enjoyed so far, at the point when its missions become more ambitious.

    Challenges to India’s expanding space ecosystem

    1. Demand does not yet match the launch capacity being built: A commercial launch business depends on a payload pipeline that Indian startups do not control, and the global small satellite launch market is already crowded with subsidised incumbents. Eg. Skyroot Aerospace flew the Vikram-S suborbital demonstration in November 2022 and Agnikul Cosmos flew a single-stage vehicle with a 3D-printed engine in May 2024, and neither has since established a regular commercial orbital cadence.
      The Fix: Anchor private launch demand with a committed government payload order book, on the model of NASA’s block procurement of commercial launches.
    2. Deep-technology capital is scarce and short in tenure: Space hardware takes years to reach revenue, which sits badly with venture funds that need an exit inside a fund life. Eg. The Rs 1,000 crore venture capital fund for the space sector announced in 2024 is small against the capital a single launch vehicle programme absorbs.
      The Fix: Convert a share of that fund into milestone-linked, non-dilutive grants for qualification testing, which is the stage where hardware companies stall.
    3. The regulator promotes and authorises the same firms it helps: IN-SPACe both promotes private participation and authorises the activity, so the body encouraging an entrant also clears its safety and liability case. Eg. The Indian Space Policy, 2023 assigned both functions to the same agency.
      The Fix: Separate the authorisation function into a distinct decision-making arm with its own record of reasons, keeping promotion and clearance in different hands.
    4. Liability for damage rests with the government whoever launches: Under the Outer Space Treaty, 1967 and the Liability Convention, 1972, the launching State is internationally liable for damage caused by an object launched from its territory. Eg. A private Indian operator’s failure abroad becomes a claim against the Union of India, not against the company.
      The Fix: Enact a domestic space activities law fixing indemnity ceilings and compulsory third-party insurance for authorised private operators.

    Conclusion

    The two halves of the plan pull in opposite directions. An agency told to concentrate on science and exploration is also being told to release the commercial work that would part-fund it, which leaves the exploration mandate resting entirely on an annual budget line. The unresolved question is whether the government intends to replace the forgone earnings with an assured allocation, or whether the restructuring is a transfer of revenue without a transfer of cost. The marker over the next Budget cycle is the direction of the Department of Space’s allocation once commercial launch work has moved out, since a flat allocation would settle the question the agency’s staff are actually asking.

    Back2Basics: IN-SPACe

    1. What it is: The Indian National Space Promotion and Authorisation Centre is an autonomous body under the Department of Space, created in 2020 as the single-window agency for private participation in space activities.
    2. What it authorises: It grants authorisation to non-government entities for launches, satellite operations, ground stations and space-based services.
    3. What it enables: It permits private entities to use ISRO’s facilities and to obtain transfer of ISRO-developed technology.
    4. Where it sits in policy: The Indian Space Policy, 2023 assigns it the promotion and authorisation functions, keeps ISRO on research, development and exploration, and leaves NewSpace India Limited to commercialise ISRO’s technologies.

    [2026] Consider the following statements about involvement of private entities in India’s space programme:

    1. IN-SPACe is an autonomous agency formed to facilitate participation of private entities.

    2. Agnikul Cosmos launched the world’s first flight using 3D-printed rocket engine.

    3. Skyroot Aerospace has developed liquid fuel for GSLV.

    ISRO: EOS-05 to be placed in elliptical geosynchronous orbit

    Why in the News

    EOS-05, India’s Earth observation satellite, is being placed in a slightly elliptical geosynchronous orbit. It is the first Indian Earth observation satellite to use a geosynchronous orbit. It was launched by GSLV-F17 and is undergoing successive orbit-raising manoeuvres.

    Geosynchronous Orbit

    • Satellite’s orbital period equals Earth’s rotational period.
    • It moves in synchrony with Earth’s rotation.
    • Geostationary orbit is a special type of geosynchronous orbit.
    • Geostationary orbit is:
      • Circular
      • Equatorial
      • At about 35,786 km altitude
    • Geosynchronous orbits can also be inclined or elliptical.

    EOS-05: Significance

    • Uses a slightly elliptical geosynchronous orbit for persistent observation.
    • Can provide continuous monitoring of a specific region.
    • Potential applications include:
      • Weather monitoring
      • Maritime surveillance
      • Strategic applications, including use by the Indian Navy.

    Limitations

    • Lower spatial resolution: Greater distance from Earth compared with LEO satellites.
    • Limited coverage: Persistent observation of one region comes at the cost of wider coverage.
    • Cloud and night limitations: Optical imaging is affected by clouds and darkness.
    • Radar complement: Satellites such as RISAT and NISAR can overcome some optical limitations.
    • Orbital congestion: Requires effective space situational awareness and collision avoidance.

    GSLV: Back to Basics

    • Full form: Geosynchronous Satellite Launch Vehicle.
    • Three-stage launch vehicle developed by ISRO.
    • Uses an indigenous cryogenic upper stage using liquid hydrogen and liquid oxygen.
    • Primarily designed for placing satellites into geosynchronous transfer orbit (GTO).
    • Lies between PSLV and LVM3 in the launch vehicle family.

    Prelims Pointers

    • Geosynchronous → Orbital period equal to Earth’s rotation.
    • Geostationary → Circular + equatorial + geosynchronous.
    • Geostationary altitude → ~35,786 km.
    • EOS-05 → Geosynchronous Earth observation mission.
    • GSLV → Geosynchronous transfer orbit.
    • PSLV → Polar/sun-synchronous missions.
    • LVM3 → Higher lift capability than GSLV.
    • IS4OM → Safe and sustainable space operations management.

    “[2018] With reference to India’s satellite launch vehicles, consider the following statements :

    1.PSLVs launch the satellites useful for Earth resources monitoring whereas GSLVs are designed mainly to launch communication satellites.

    2.Satellites launched by PSLV appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth.

    3.GSLV Mk III is a four-stage launch vehicle with the first and third stages using solid rocket motors, and the second and fourth stages using liquid rocket engines.

  • Ground control

    Why in the News

    Nine employee associations of the Indian Space Research Organisation (ISRO) have written to the chairman seeking clarity on staff strength, recruitment and the outsourcing of core functions. The letter was sent on the day the agency recorded its largest success of the year, the launch of its first geosynchronous imaging satellite, EOS-05, on the Geosynchronous Satellite Launch Vehicle (GSLV). The grievance follows from the Indian Space Policy of April 2023, which signalled that ISRO would eventually stop building commercial satellites and launch vehicles and would concentrate on exploratory missions. ISRO has stated that it will not be privatised or reduced, and the Indian National Space Promotion and Authorisation Centre (IN-SPACe), the body set up to enable private participation, has stated that the agency will not be diminished and that only industry’s role must grow. Neither institution has addressed the concern the letter actually raises, which is the loss of jobs. The underlying question is whether the sector’s direction still matches its founding principle, that space technology is an instrument of social development rather than a contest for prestige.

    What does the Indian Space Policy, 2023 set out?

    1. A division of roles: The policy separates the space sector into ISRO, IN-SPACe and NewSpace India Limited, and assigns each a distinct function instead of leaving all of them with ISRO.
    2. ISRO’s redefined remit: ISRO is to move out of routine operational and commercial production of satellites and launch vehicles, and towards research and development in advanced technologies and exploratory missions.
    3. IN-SPACe as the single window: IN-SPACe authorises and supervises the space activities of private entities, so a company deals with one authorising body rather than with the operator of the launch infrastructure.
    4. NewSpace India Limited as the commercial arm: The public sector company under the Department of Space is responsible for commercialising space technologies and platforms developed with public money.

    What are the employee associations asking for?

    1. Staff strength and recruitment: The associations want stated numbers on sanctioned strength and future recruitment, since a shrinking mandate implies a shrinking establishment.
    2. Outsourcing of core functions: The letter distinguishes contracting out manufacturing from contracting out functions the agency treats as core, and seeks clarity on where that line now falls.
    3. The institutional replies avoid the question: Both the agency and the authorisation body have answered on the agency’s continued existence, which was not what was asked.
    4. The timing is the point: The grievance surfaced on a day of technical success, which indicates that the concern is about the institution’s trajectory and not about its capability.

    Which vision of the space programme is the sector following?

    1. The founding principle: The programme was built on a refusal to be drawn into space races and on the use of space technology as a tool for social development, meaning communication, weather and resource mapping for domestic needs.
    2. The competing image: The alternative is space as an emblem of national power, membership of a small club of space faring countries, and a proliferation of startups as evidence of arrival.
    3. The 2035 test the sector is being set: If the sector is to be a source of export earnings and a nucleus of value added services that absorbs skilled labour and creates jobs, hard choices taken now may be justified.
    4. Where the line falls: Joining a bandwagon driven by billionaire ambition and notions of conquest is a different objective from either, and the case for restructuring collapses if that is what it delivers.

    What does the comparison with NASA show?

    1. The budget gap: The National Aeronautics and Space Administration (NASA) operates on $24.4 billion against the Department of Space’s Rs 13,705 crore, roughly 16 times larger.
    2. NASA also contracted: NASA’s budget fell from 0.7% of American gross domestic product in 1966 to 0.1% now, so its own shift to contracting out followed a sustained loss of fiscal share.
    3. Its establishment shrank with it: NASA’s civil service headcount fell from about 36,000 at the peak of the Apollo programme to about 14,000 today, which is the trajectory ISRO’s employees are reading against.
    4. The unaddressed comparator: China’s space programme has not been seriously reckoned with in India’s planning, and it is the one operating at a scale and cadence that directly bears on India’s position.

    Is the new private base the same as the old one?

    1. ISRO never made everything itself: Unlike NASA in its early years, which designed and made every component, ISRO has always had a manufacturing relationship with private industry, including Walchandnagar Industries and Larsen and Toubro.
    2. The entrants are of a different type: The current activity is not established companies building on decades of manufacturing experience but new entrants funded by foreign capital that may not stay.
    3. The business model has shifted: Most new entrants are interested in satellite data as a service rather than in building hardware, which is a different industrial base from the one that supplied the agency.
    4. The transferable capability is therefore narrower: A vendor base built on data services cannot absorb the manufacturing functions ISRO is being asked to shed.

    Challenges to ISRO’s restructuring

    1. In house capability is easy to lose and slow to rebuild: Skills that live in the hands of a small number of engineers disappear once the work is contracted out and the staff are not replaced. Eg. Cryogenic engine development took India close to two decades to master after external supply was cut off.
      The Fix: Ring fence a defined set of critical technologies as retained in house capability, with recruitment sanctioned against them irrespective of outsourcing elsewhere.
    2. The private demand base is thin: A domestic space economy built on data services has few anchor customers other than government departments, so private capacity depends on public orders it is meant to replace. Eg. Earth observation demand in India is dominated by central and State government users.
      The Fix: Commit an anchor procurement volume for satellite data and launch services over a fixed multi year period, so private capacity is built against contracted demand.
    3. Foreign capital in the entrant base is mobile: Startups funded by capital that can exit quickly cannot be relied on to hold strategic capability through a downturn. Eg. Global space venture funding has moved sharply between years, tightening after periods of expansion.
      The Fix: Condition the transfer of any strategic technology on domestic ownership thresholds and on a minimum period of operation in India.
    4. Transferring a launch vehicle is harder than transferring a design: Handing production of a vehicle to industry moves drawings but not the accumulated process knowledge that makes a launch repeatable. Eg. The Small Satellite Launch Vehicle technology transfer to industry involved an extended period of hand holding rather than a clean handover.
      The Fix: Structure every technology transfer with a defined number of jointly executed missions before the agency withdraws.
    5. The regulatory body is also the promoter: IN-SPACe both promotes private participation and authorises it, so the function that grants approvals is the function measured on how many approvals it grants. Eg. Authorisation and promotion sit within one body rather than in separate agencies.
      The Fix: Separate the authorisation function into a statutory regulator with its own appointment process, leaving promotion with the existing body.

    Conclusion

    The agency’s technical record is not what is in question, and a successful launch is precisely why the staffing letter is difficult to dismiss. What is unresolved is that two institutions have given assurances about the agency’s survival while declining to state what happens to the people inside it, and an assurance that avoids the question asked is not an answer. The concrete thing to watch is whether the Department of Space publishes a transparent policy stating sanctioned staff strength, the recruitment pipeline and the specific functions that will remain in house.

    Back2Basics: Geosynchronous Satellite Launch Vehicle

    1. What it is: A three stage Indian launch vehicle designed mainly to place communication and other heavier satellites into geosynchronous transfer orbit.
    2. Its stages: It uses a solid first stage with liquid strap on boosters, a liquid second stage, and an indigenous cryogenic upper stage.
    3. Why the cryogenic stage matters: Cryogenic propulsion burns liquid hydrogen with liquid oxygen at very low temperatures, giving the high efficiency needed for the final push to a high orbit, and India developed it after external supply was withheld.
    4. Its record: The vehicle has a higher failure rate than India’s Polar Satellite Launch Vehicle, which is why each successful GSLV flight is treated as a significant outcome.

    [2026] Consider the following statements about involvement of private entities in India’s space programme:

    1. IN-SPACe is an autonomous agency formed to facilitate participation of private entities.

    2. Agnikul Cosmos launched the world’s first flight using 3D-printed rocket engine.

    3. Skyroot Aerospace has developed liquid fuel for GSLV.

  • ISRO’s role is by no means diminishing: space officials

    ISRO’s role is by no means diminishing: space officials

    Why in the News

    Nine Indian Space Research Organisation (ISRO) employee associations have written a joint letter dated 4 September seeking written clarification on whether the government intends to transfer the agency’s launch vehicle and satellite manufacturing to private firms.

    What did the employee associations actually ask?

    1. Whether the position is an approved decision: They asked whether the stated future of ISRO not manufacturing launch vehicles represents an approved Space Commission decision.
    2. What happens to the workforce: They asked what would happen to sanctioned strength and recruitment over the next five to 10 years.
    3. Whether they will be consulted: They asked whether the associations would be consulted before irreversible decisions are taken.
    4. Where the letter went: It was addressed to the Secretary, Department of Space and Chairman, ISRO, and copied to the Confederation of Central Government Employees and Workers.

    What is the official position on ISRO’s role?

    1. The role is stated as undiminished: IN-SPACe’s chairman said the direction is not a smaller ISRO but a larger Indian space ecosystem, with ISRO pushing the technological frontier.
    2. Privatisation is denied outright: ISRO’s clarification stated that the agency will neither be privatised nor have its importance reduced.
    3. Transfer is distinguished from withdrawal: Handing over a mature technology does not amount to leaving that domain, on the agency’s stated reasoning.
    4. Ownership stays public: Critical national space infrastructure will remain owned by the government.

    How is the division of labour defined?

    1. The 2020 reforms set the structure: The reforms were aimed at expanding the overall ecosystem, with IN-SPACe authorising non-government participation and NewSpace India Limited (NSIL) commercialising mature capabilities.
    2. Industry takes the mature end: Industry is to increasingly manufacture and scale launch vehicles and satellites whose technology is settled.
    3. The agency keeps the unsettled end: ISRO is to concentrate on advanced research and development, scientific and strategic missions, and infrastructure too complex for private developers.
    4. The policy instrument: The arrangement is described as an ISRO-led national space ecosystem, institutionalised through the Indian Space Policy 2023.

    What does the reform record show so far?

    1. Firm formation: India now has over 450 space start-ups, against a handful in 2020.
    2. The revenue target: The space economy is roughly $8.4 billion and the stated aim is to grow it to $44 billion by 2033.
    3. The retained programmes: The Bharatiya Antariksh Station by 2035 and an Indian crewed lunar mission by 2040 are named as the missions ISRO itself will build toward.

    Why could employees only raise this as associations?

    1. They are outside the industry definition: Department of Space employees are exempted from the statutory definition of industry.
    2. They cannot unionise: That exemption means they cannot form trade unions to bargain on employment terms.
    3. The available channel is narrower: They organise instead as service associations recognised under the Central Civil Services (Recognition of Service Associations) Rules, 1993, which permits representation rather than negotiation.

    Challenges to an ISRO-led national space ecosystem

    1. Government remains the anchor customer: Private launch and satellite demand is thin, so firms depend on public orders for volume. Eg. NewSpace India Limited awarded the Polar Satellite Launch Vehicle industrial production contract for five vehicles to a Hindustan Aeronautics Limited and Larsen and Toubro consortium in 2022.
      The Fix: Publish a multi-year public launch and satellite procurement calendar, so firms can size capacity against committed demand rather than announcements.
    2. Technology transfer terms decide whether industry can compete: A transferred design without production know-how and test infrastructure leaves the recipient dependent on the agency. Eg. ISRO transferred the Small Satellite Launch Vehicle technology to Hindustan Aeronautics Limited in 2025.
      The Fix: Attach test facility access and a defined hand-holding period to every transfer agreement, with milestones the recipient must independently clear.
    3. Long-gestation capital is scarce: Launch and propulsion ventures need patient capital across development cycles that outlast most venture fund horizons. Eg. The Union Budget for 2024-25 announced a Rs 1,000 crore venture capital fund for the space sector for this reason.
      The Fix: Route that fund through milestone-linked tranches tied to qualification tests, rather than as equity at a single valuation point.
    4. Foreign investment rules still differ by segment: Investment caps vary across launch vehicles, satellites and components, which complicates raising capital for an integrated firm. Eg. The 2024 foreign direct investment revision set different automatic-route thresholds for satellite manufacturing, launch vehicles and component supply.
      The Fix: Publish a single classification note stating which activity falls in which segment, so a firm knows its cap before it raises capital.

    Conclusion

    Both sides agree that industry should build what is settled and the agency should build what is not. The disagreement is over where that boundary currently sits and who has the authority to move it. The workforce question the associations raised is the one neither reply engaged with. Until the Department of Space states its recruitment intent in numbers, the assurance rests on stated direction rather than on anything an employee can verify.

    Back2Basics

    1. NewSpace India Limited: The commercial arm of the Department of Space, incorporated in March 2019 as a central public sector enterprise.
    2. Predecessor: It took over the commercial role earlier held by Antrix Corporation, which now handles a narrower marketing mandate.
    3. Business model: It operates on a demand-driven model, owning and operating satellites and launches for identified customers rather than only marketing surplus capacity.
    4. Headquarters: It is based in Bengaluru and reports to the Department of Space.

    [2026] Consider the following statements about involvement of private entities in India’s space programme:

    1. IN-SPACe is an autonomous agency formed to facilitate participation of private entities.

  • ISRO staff question trajectory of space privatisation, want chief to clarify

    Why in the News

    Key employee associations at the Indian Space Research Organisation (ISRO) have written to the ISRO chairperson seeking a written clarification on whether ISRO’s exit from launch vehicle manufacture is an approved decision of the Government of India, the Space Commission or the Department of Space. The letter follows a public statement by the chairperson of the Indian National Space Promotion and Authorization Centre (IN-SPACe), the nodal body under the Department of Space set up in 2020 to open India’s space sector to private participation, that ISRO will eventually not manufacture any launch vehicles. The associations say the statement was never followed by any formal communication from the Department of Space explaining the policy, its legal basis, its timeline or its effect on staff. The letter was sent hours after ISRO launched an earth observation satellite aboard a Geosynchronous Satellite Launch Vehicle (GSLV), ending a months-long hiatus. The dispute is between a promotion body announcing the direction of travel in public and a workforce with no document to read it in.

    What did the statement claim about ISRO’s future work?

    1. Launch vehicles move out: ISRO will eventually not manufacture any launch vehicles, and that work will be done by the private sector or a public sector undertaking.
    2. Routine satellites move out too: ISRO will not build what were described as day in day out satellites.
    3. What is retained is narrowly drawn: ISRO will build satellites for special purposes, for orbits meant for scientific research, or to develop new technology that is then transferred to the private sector.

    What are the employee associations asking for?

    1. The status of the statement: The letter asks the chairperson to issue a written clarification on whether the statements represent an approved decision of the Government of India, the Space Commission or the Department of Space.
    2. Who has signed it: It carries signatures of representatives from across ISRO’s centres, including the Space Applications Centre and the Liquid Propulsion Systems Centre.
    3. What the letter asks to be defined: It seeks answers on ISRO’s future role as a public organisation, on whether public sector undertakings will also be excluded from manufacturing work, on the safeguards available to current employees, and on how publicly funded technologies are being transferred to private companies.
    4. A consultation demand: It asks whether employee associations will be consulted before any irreversible decision affecting the agency’s structure, mandate or staffing is finalised.

    Why do the associations treat this as a threat to the organisation?

    1. The activities named are the core, not the periphery: The associations describe those activities as ISRO’s core competence, and say withdrawing from them threatens the organisation’s long-term viability.
    2. Career expectations are unsettled: Employees who built careers around ISRO’s stability and public character now face uncertainty about what the organisation will be.
    3. Recruitment is the compounding effect: Recruitment is already limited by vacancies and attrition, and a shrinking intake discourages young professionals who see ISRO as a respected public sector career path.

    How far has the transfer to industry already gone?

    1. The stated policy since 2020: The government’s approach has been for ISRO to mentor emerging companies and gradually shift routine work to them, with ISRO focusing on missions of scientific and strategic significance.
    2. The transfers already made: ISRO has transferred around 120 technologies to industry, including the Small Satellite Launch Vehicle and the Polar Satellite Launch Vehicle (PSLV).
    3. Infrastructure is being built for the same segment: The new spaceport at Kulasekharapatnam is expected to focus on small satellite launches, a segment where private capability is already fairly advanced.

    Where does expert opinion sit on the direction?

    1. The opening is defended as overdue: The Deputy Director General of the Manohar Parrikar Institute for Defence Studies and Analyses said the sector’s opening up was overdue and could have helped India capture a larger share of the global market sooner.
    2. Some shifting is treated as natural: With ISRO focused on Gaganyaan, the Bharatiya Antariksh Station and a crewed lunar mission, some functions would move to private players as a matter of course.
    3. The limit drawn is on launch: Launch services and vehicle development remain core to ISRO’s mandate, and ISRO should remain capable of launching some of its own satellites, especially the strategic ones.
    4. The counter-example cited is American: The stated caution is that India should not reach the position of the National Aeronautics and Space Administration (NASA), which is completely dependent on a single commercial provider for its launches.

    Challenges to India’s space sector privatisation

    1. The opening rests on policy, not statute: Authorisation, liability and licensing of private space activity are governed by executive policy documents rather than by a law passed by Parliament. Eg. A draft Space Activities Bill was circulated for comment in 2017 and was never introduced, and the Indian Space Policy, 2023 has filled that space instead.
      The Fix: Enact a space activities law fixing licensing conditions, third-party liability and government indemnity, so operators and the regulator work to statutory terms.
    2. Promotion and authorisation sit in the same body: The agency that promotes private entry also authorises it, and the incumbent it is displacing reports to the same department. Eg. IN-SPACe, ISRO and NewSpace India Limited all sit under the Department of Space.
      The Fix: Separate the authorisation function into a body with its own statutory mandate, leaving promotion and hand-holding with IN-SPACe.
    3. Publicly funded designs move out without a published valuation: Technology developed at public cost is handed to firms without the consideration or the continuing support obligations being disclosed. Eg. Production of the Small Satellite Launch Vehicle was transferred through a competitive bid won by Hindustan Aeronautics Limited.
      The Fix: Publish the consideration, the support commitment and the reciprocal obligations for every transfer above a stated value.
    4. Capability decays when it is not exercised: Launch vehicle engineering skill is retained by building vehicles, not by supervising others building them. Eg. India’s cryogenic upper stage took roughly two decades to reach operational service after technology transfer from Russia was blocked in the 1990s.
      The Fix: Attach a minimum in-house build and integration requirement to each new vehicle programme so design teams retain hands-on work.

    Conclusion

    A structural change of this size is being read off a public remark rather than a departmental order, and that is the substance of the objection rather than the policy direction itself. Employees can contest a document. They cannot contest a statement that nobody has confirmed to be policy. The written clarification the letter seeks is the marker to watch. Whether it names the Space Commission as the deciding authority, or declines to, will show where the decision on ISRO’s manufacturing role actually sits.

    Back2Basics: IN-SPACe

    1. It is an autonomous single-window agency under the Department of Space, announced in 2020 and set up to enable private participation in space activities.
    2. It authorises and supervises space activities carried out by non-government entities in India.
    3. It arranges the sharing of ISRO’s facilities, expertise and technical data with private operators.
    4. It is distinct from NewSpace India Limited, which is the commercial arm that markets and sells ISRO’s products and services.

  • ISRO launches advanced imaging satellite EOS-05

    ISRO launches advanced imaging satellite EOS-05

    Why in the News

    The Indian Space Research Organisation (ISRO) has launched the advanced earth observation satellite EOS-05 aboard the Geosynchronous Satellite Launch Vehicle (GSLV-F17).

    What is EOS-05?

    1. What makes it a first: It is India’s first dedicated imaging satellite operating from geosynchronous orbit, where a satellite’s orbital period matches the earth’s rotation so it holds position over the same region.
    2. What it carries: The satellite has multi band operating capabilities and an operational life of nine years.
    3. What it replaces: It takes the place of EOS-03, lost in the unsuccessful GSLV-F10 mission of August 2021.
    4. Where it is now: ISRO has confirmed that the valves are operating, the solar panel is deployed and the satellite’s health is intact, and the orbit will be raised over the coming days to place it on the geo platform.

    Why does imaging from geosynchronous orbit matter?

    1. It removes the revisit gap: A low earth orbit imaging satellite passes over a given area only periodically, while a geosynchronous platform holds the same region in view continuously.
    2. The applications are time sensitive: Near real time imagery serves agriculture, environment monitoring and disaster management, where the value of an image collapses if it arrives days after the event.
    3. The data is described as strategic: ISRO has stated that the platform will supply important strategic data supporting “national activities”, which is the standard formulation for defence and security use.
    4. The trade off is resolution: Ground resolution falls as orbital distance rises, so a geosynchronous imager buys persistence at the cost of the fine detail a low orbit satellite returns.

    What does the mission say about the launch vehicle?

    1. It was the heaviest payload the vehicle has carried: The 2,367 kg satellite is the heaviest ISRO has injected using this launch vehicle.
    2. The growth is measurable against the first flight: The first GSLV flight, GSLV-D1, carried a payload of 1,536 kg.
    3. The gain came from two specific changes: ISRO has attributed the improvement to optimising the vehicle’s structural mass and improving its propulsion systems.
    4. The vehicle configuration: The GSLV is a three stage, 51.7 metre vehicle with a lift off mass of 420.5 tonnes, and its third stage is cryogenic (using propellants stored as liquids at extremely low temperatures, which yields higher efficiency than conventional stages).
    5. The mission count: This was the 19th GSLV mission and the 107th launch from Sriharikota.

    Why had ISRO stopped launching?

    1. Two consecutive vehicle failures: The PSLV-C61 mission failed on 18 May 2025, and the PSLV-C62 mission carrying the EOS-N1 earth observation satellite failed on 12 January 2026.
    2. The response was a deliberate halt: ISRO adopted a cautious approach after the back to back failures and refrained from carrying out further launches.
    3. The cost was an entire quarter: Seven missions, including this one, had been scheduled for the first quarter of 2026, and no satellite was launched during the period.

    Challenges to India’s earth observation programme

    1. Launch cadence lags the manifest: A single quarter of stood down launches pushes an entire year’s schedule, and satellites waiting for a slot age against their design windows. Eg. Seven missions planned for the first quarter of 2026 were carried forward without a single flight.
      The Fix: Move routine earth observation payloads onto the Small Satellite Launch Vehicle and commercial providers, so a review of one vehicle does not freeze the whole manifest.
    2. The cryogenic stage remains the vehicle’s hardest element: The GSLV’s performance depends on a stage that took India close to two decades to prove. Eg. The first fully successful flight of the indigenous cryogenic upper stage came only with GSLV-D5 in January 2014.
      The Fix: Sustain a parallel production line and ground test cadence for cryogenic stages, so a flight failure does not idle the vehicle for want of a qualified replacement stage.
    3. Optical imaging fails when it is needed most: An optical imager cannot see through cloud, and India’s worst flood and landslide events occur during the monsoon under continuous cloud cover. Eg. Disaster response during the monsoon depends on radar imaging satellites such as EOS-04 rather than on optical payloads.
      The Fix: Pair the geosynchronous optical platform with a scheduled radar imaging constellation, so persistent coverage survives the cloud season.
    4. Imagery is only as useful as its downstream users: Data value depends on agencies and states being able to ingest and act on it rather than on the satellite alone. Eg. Access to national imagery is routed through the Bhuvan platform and the National Remote Sensing Centre, and uptake varies sharply across state departments.
      The Fix: Fund state level remote sensing application centres with standing analyst posts, so imagery reaches district administrations as advisories rather than as raw files.

    Conclusion

    The satellite is in a transfer orbit and not yet at its station, so the mission’s outcome is settled only once orbit raising is complete and the platform is commissioned. The capability it brings is persistence over one region rather than sharper pictures, which suits warning and monitoring more than reconnaissance. The launch pause has ended on the vehicle that had the weaker record, which is the more demanding of the two returns to flight. What to watch is whether the remaining missions deferred from the first quarter of 2026 now fly on schedule, since a single successful launch does not by itself restore a cadence.

    “[2018] With reference to India’s satellite launch vehicles, consider the following statements :

    1.PSLVs launch the satellites useful for Earth resources monitoring whereas GSLVs are designed mainly to launch communication satellites.

    2.Satellites launched by PSLV appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth.

    3.GSLV Mk III is a four-stage launch vehicle with the first and third stages using solid rocket motors, and the second and fourth stages using liquid rocket engines.

  • Opposition raises concerns over ‘weakening’ of ISRO; Centre hits back

    Why in the News

    Opposition parties in Parliament questioned the government’s push to privatise parts of the space sector, citing recent resignations at the Indian Space Research Organisation (ISRO) and asking whether the shift toward private participation is weakening the organisation. The government responded by citing the $44-billion space economy target, the Kulasekarapattinam spaceport under development, and continued investment in the Sriharikota launch facility, arguing that private participation is expanding, not displacing, ISRO’s role.

    What is the Opposition’s specific concern?

    1. Reported resignations at ISRO cited as evidence of institutional strain: Opposition members pointed to recent resignations at ISRO as a sign that the organisation is losing talent, and linked this to the government’s parallel push to open the space sector to private companies.
    2. Question framed as public-versus-private capacity, not merely personnel: The core question raised was whether directing new space-sector opportunities toward private players comes at the cost of ISRO’s own institutional capacity and morale, rather than being framed as a narrow human-resources issue alone.

    How did the government respond?

    1. The $44-billion space economy target as the framing device: The government’s rebuttal centred on India’s targeted space economy size, cited at $44 billion, arguing that reaching this scale requires private capacity in addition to, not instead of, ISRO’s own programmes.
    2. The Kulasekarapattinam spaceport as evidence of expansion: The government cited the Kulasekarapattinam spaceport, under development in Tamil Nadu specifically to support the small-satellite launch vehicles that private and ISRO missions alike are expected to use, as evidence of continuing public investment in launch infrastructure.
    3. Continued investment in Sriharikota: The government also pointed to ongoing investment in the Sriharikota launch facility, ISRO’s principal spaceport, as evidence that ISRO’s core launch infrastructure is being expanded rather than run down.

    What is the structural relationship between ISRO and India’s growing private space sector?

    1. IN-SPACe as the facilitating body for private entry: The Indian National Space Promotion and Authorisation Centre (IN-SPACe), an autonomous body under the Department of Space, was created specifically to authorise and facilitate private-sector participation in space activities that were previously the exclusive domain of ISRO.
    2. NewSpace India Limited as the commercial arm: NewSpace India Limited, the public sector undertaking under the Department of Space, commercialises ISRO-developed technology and manages the transfer of ISRO capabilities to industry.
    3. Private launch capability is still at an early, unproven stage: Private Indian space companies have made progress, including new propulsion technologies, but have not yet demonstrated launch capability at the scale or reliability of ISRO’s own vehicles, meaning private participation currently supplements rather than substitutes for ISRO’s launch role.

    Conclusion

    The exchange reflects a genuine disagreement over sequencing rather than over the direction of India’s space policy: both sides accept that private participation is expanding, and the dispute is over whether that expansion is currently coming at ISRO’s institutional expense. Whether the resignations flagged by the Opposition reflect a broader retention problem, or are within the range any large scientific organisation experiences, will only be clear from data the government has yet to place before Parliament.

    Back2Basics: Indian National Space Promotion and Authorisation Centre (IN-SPACe)

    1. An autonomous, single-window agency under the Department of Space, established to authorise, promote, and regulate private-sector space activities in India.
    2. Created as part of the 2020 space-sector reforms that opened satellite building, launch vehicle development, and space-based services to private Indian companies.
    3. Functions separately from ISRO, which retains its own research, development, and launch mandate, so the two operate as parallel rather than competing structures.
    4. Reviews and clears private-sector proposals for satellite launches, ground infrastructure, and related space activities.

  • Global space norms find a firm footing in India’s new re-entry rules

    Global space norms find a firm footing in India’s new re-entry rules

    Why in the News

    The Indian National Space Promotion and Authorisation Centre (IN-SPACe) has released India’s first guidelines on planned re-entry, requiring any Indian entity undertaking such a re-entry to obtain its authorisation, whether the re-entry occurs within or outside Indian territory.

    What is a planned re-entry?

    1. The defining test is intent and survivability: Objects designed to survive re-entry, or intentionally controlled towards a particular landing or impact area, require separate authorisation. This is what makes a re-entry planned.
    2. What falls outside the definition: Objects expected to burn up, melt or fragment sufficiently during natural orbital decay do not count as a planned re-entry.
    3. Why the distinction carries regulatory weight: The category separates a return that must be assessed and cleared in advance from one that requires no clearance, so the definition determines the reach of the entire framework.

    Why has re-entry become a governance problem now?

    1. The historical baseline was negligible: For many decades there were few rocket launches and few new satellites in orbit each year, so there were also few re-entries.
    2. The consequences used to be trivial: Most of those re-entries simply burned up in the atmosphere with little consequence.
    3. The orbital population has changed: Low-earth orbit, the band of orbits closest to the earth where most satellites operate, now hosts several thousand satellites, with private companies planning for many more.
    4. Deliberate de-orbiting has become routine: Satellite operators are also deliberately bringing satellites down at the end of their operational lives as part of post-mission disposal, in great numbers.
    5. The physical risks are specific: A spacecraft returning to the earth has to negotiate many risks, including deviating from its planned path and breaking up into smaller pieces.
    6. The risks cross jurisdictions: A returning object may affect airspace and maritime zones, and may potentially crash in the territory or jurisdiction of another state, which makes re-entry a governance problem as well as a physics problem.

    What are the three important elements of the guidelines?

    1. Accountability: Any Indian entity undertaking a planned re-entry, whether within or outside Indian territory, now requires IN-SPACe authorisation.
    2. Foreign operators must route through an Indian entity: Non-Indian entities seeking to undertake planned re-entry over Indian territory must route the activity through an Indian-incorporated entity, such as a subsidiary, joint venture or partnership.
    3. The Indian entity carries the compliance duty: That Indian entity is responsible for complying with Indian laws, regulations and national security requirements.
    4. Why the accountability gap exists: Commercialisation separates ownership from consequence, since the spacecraft may belong to a private company and the effects of its return lie across maritime zones and jurisdictions. India has responded by attaching regulatory responsibility to a re-entering entity before the risk materialises.
    5. Risk must be acceptable: The expected casualty risk must remain below 1 in 10,000, supported by survivability and ground-casualty assessments.
    6. Failure scenarios must be modelled and shared: Operators have to analyse and share failure scenarios, fragmentation patterns, ballistic coefficients, de-orbit plans, flight-path angles and danger zones.
    7. Surviving and hazardous components must be identified: They must identify components likely to survive re-entry, and hazardous systems such as batteries and pressure vessels.
    8. A number makes sustainability measurable: By requiring quantitative studies and attaching a figure to the acceptable risk threshold, the guidelines make sustainability measurable and therefore trackable.
    9. Permissions: IN-SPACe will re-verify the latest re-entry parameters approximately three months before the proposed operation.
    10. A post-launch decision needs six months’ notice: If a planned re-entry is decided upon after launch, the operator must apply at least six months in advance.
    11. Airspace and maritime warnings at 45 days: Operators must obtain an IN-SPACe advisory note to issue warnings to airborne and marine vessels in the re-entry area at least 45 days before the re-entry begins.
    12. A foreign jurisdiction requires that state’s clearance: If a re-entry site falls within the territorial control of a non-Indian state, including its exclusive economic zone, the applicant must submit the relevant clearance or authorisation from that state.
    13. The checkpoints are intervention windows: These checkpoints give the regulator fixed windows and mechanisms to intervene when re-entry parameters change after the mission has launched, or when the risk pattern changes.

    What international framework do the guidelines translate?

    1. The development period: For nearly two decades the international community has developed principles for sustainable space activities.
    2. The two leading instruments: They are the Inter-Agency Space Debris Coordination Committee’s Space Debris Mitigation Guidelines, and the Guidelines for the Long-term Sustainability of Outer Space Activities of the United Nations Committee for the Peaceful Uses of Outer Space.
    3. The treaty foundation: Article IX of the Outer Space Treaty 1967 provides an important foundation for environmental responsibility in the conduct of space activities.
    4. The working definition of sustainability: The UN Guidelines define sustainability as maintaining space activities while preserving the outer space environment for future generations.
    5. The structural weakness of that architecture: Most of the contemporary sustainability architecture works on guidelines and other similar forms of soft law, which operators are not obligated to follow.
    6. How the national regulator closes it: The IN-SPACe guidelines solve this problem for India by tying an operator’s fragmentation analysis and insurance policies to the national regulator, which converts a voluntary standard into a condition of permission.

    How do the guidelines handle liability?

    1. The treaty position on liability: The Space Liability Convention 1972 places absolute liability on a launching state for damage caused by its space object on the surface of the earth, or to aircraft in flight.
    2. The state carries the claim, not the operator: Absolute liability means the launching state answers for the damage regardless of fault, so a private failure becomes a sovereign liability by default.
    3. The guidelines invert that internally: Operators must undertake planned re-entries at their own risk, and they remain liable for third-party damage and claims.
    4. Indemnity to the government: Operators indemnify the Government of India and its agencies for liability incurred under India’s international commitments.
    5. Insurance as the backing: Operators must satisfy the applicable third-party insurance requirements, so the indemnity is funded rather than merely promised.

    Challenges to the IN-SPACe planned re-entry guidelines

    1. The regulator has no statutory backing: IN-SPACe functions as the sector’s regulator without legislative authority, so its guidelines rest on executive policy rather than on an Act. Eg. India has no dedicated space activities legislation, and the Indian Space Policy 2023 is a policy document. Fix. Enact a space activities law placing authorisation, liability and penalties on a statutory footing.
    2. The regulator sits inside the body it regulates: IN-SPACe authorises activities of private companies and government entities including ISRO, and it operates under the Department of Space. Eg. The same department is both the policy custodian and the parent of the entity it must clear. Fix. Place IN-SPACe under an independent appointments and reporting structure, with appeals lying outside the Department of Space.
    3. No appellate route for a refused authorisation: An operator refused authorisation, or held to a risk finding it disputes, has no defined appeal forum. Eg. The guidelines fix a casualty risk threshold without naming any forum before which an operator may contest a risk finding. Fix. Constitute a space disputes appellate tribunal with technical members, on the model used for telecom and electricity regulation.
    4. Verification capacity lags the requirement: A casualty risk below 1 in 10,000 must be independently verifiable, and that requires tracking and modelling capability the regulator does not itself hold. Eg. Debris tracking rests on ISRO’s Project NETRA, which is oriented to collision avoidance rather than to re-entry survivability audit. Fix. Build an independent re-entry analysis cell with access to radar and optical tracking data, empanelling accredited third-party assessors.
    5. Insurance capacity is untested at Indian scale: Third-party space insurance is a thin market, and a small operator may be unable to price cover for a low-probability, high-consequence event. Eg. Indian space startups have grown from a handful to around 200, most of them without balance sheets that carry catastrophic risk. Fix. Create a graded liability cap with a government-backed pool above it, on the model used for civil nuclear liability.

    “[2026] Consider the following statements about involvement of private entities in India’s space programme:

    1. IN-SPACe is an autonomous agency formed to facilitate participation of private entities.

    2. Agnikul Cosmos launched the world’s first flight using 3D-printed rocket engine.

    3. Skyroot Aerospace has developed liquid fuel for GSLV.
