    lvm3

    The ISRO’s heaviest rocket, Launch Vehicle Mark 3 (LVM3 or GSLV Mark 3) has successfully put into orbit 36 satellites of the U.K.-based OneWeb.

    Also in news

    • The ISRO has renamed the Geosynchronous Satellite Launch Vehicle (GSLV) Mark -III as Launch Vehicle Mark-III, mainly to identify its task of placing satellites into a variety of orbits.

    What is LVM3?

    • LVM3 (erstwhile GSLV) is an expendable space launch vehicle designed, developed, and operated by the ISRO to launch satellites and other space objects into Geosynchronous Transfer Orbits.
    • It is 49.13 m tall and tallest among all other vehicles of ISRO.
    • It is a three-stage vehicle with a lift-off mass of 420 tonnes.
    • ISRO first launched LVM3 on April 18, 2001 and has made 13 launches since then.

    Stages in LVM3

    • The first stage comprises S139 solid booster with 138-tonne propellant and four liquid strap-on motors, with 40-tonne propellant.
    • The second stage is a liquid engine carrying 40-tonne of liquid propellant.
    • The third stage is the indigenously built Cryogenic Upper Stage (CUS) carrying 15-tonne of cryogenic propellants.

    Difference between PSLV and LVM3

    • LVM3 has the capability to put a heavier payload in the orbit than the Polar Satellite Launch Vehicle (PSLV).
    • PSLV can carry satellites up to a total weight of 2000 kg into space and reach up to an altitude of 600-900 km.
    • LVM3 can carry weight up to 5,000 kg and reach up to 36,000 km.
    • PSLV is designed mainly to deliver earth observation or remote sensing satellites, whereas, LVM3 has been designed for launching communication satellites.
    • LVM3 delivers satellites into a higher elliptical orbit, Geosynchronous Transfer Orbit (GTO) and Geosynchronous Earth Orbit (GEO).

    Upgrades brought by LVM3

    • The LVM3 is capable of lifting much heavier satellites than the GSLV Mk II with a bigger cryogenic upper stage and a larger first stage.
    • Both GSLV Mk II and LVM3 are three-stage vehicles, while the PSLV, which launches to low earth polar orbits, is a four-stage vehicle.
    • The GSLV Mk-II can place up to 2,500kg in geosynchronous orbits and up to 5,000kg to low earth orbit.
    • By comparison, the LVM3 can lift 4,000kg to GTO and up to 8,000 kg to LEO.

  • Five new varieties to expand India’s Basmati platter

    basmati

    Five new Basmati varieties, developed by a group of scientists from Indian Agriculture Research Institute (IARI), in 2020 and 2021 are all set to bring revolutionary changes in the way this type of paddy is cultivated in the country.

    About Basmati Rice

    • Basmati, pronounced is a variety of long, slender-grained aromatic rice which is traditionally grown in India, Pakistan, and Nepal.
    • As of 2019, India accounted for 65% of the international trade in basmati rice, while Pakistan accounted for the remaining 35%.
    • Many countries use domestically grown basmati rice crops; however, basmati is geographically exclusive to certain districts of India and Pakistan.
    • India accounts for over 70% of the world’s basmati rice production.
    • The areas which have a geographical indication are in the states of Punjab, Haryana, Himachal Pradesh, Delhi, Uttarakhand, Western Uttar Pradesh and Jammu and Kashmir

    Export potential of Basmati

    • Basmati rice has a market abroad and brings about ₹30,000 crore in foreign exchange every year.
    • While 75% of the export is to West Asian countries, European Union countries also import Indian Basmati.
    • However, recently, the export to EU countries faced certain hurdles due to the increase in the pesticide residue levels in the rice from India.

     

     

  • What is Web 3.0?

    web

    India has a rapidly-growing Web3 ecosystem with more than 450 active start-ups in the space that raised $1.3 billion in funding till April 2022.

    What is Web 3.0?

    • Web3 help users interact with decentralized applications built on blockchain technology.
    • Web3 technologies like distributed ledgers, artificial intelligence, Metaverse and others aim to create the next-generation internet, which is accessible to everyone and offers benefits.
    • Web2 is what we know and use today.

    Why need Web 3?

    • Centralization has helped onboard billions of people to the World Wide Web (www) and created the stable, robust internet infrastructure.
    • At the same time, a handful of centralized entities have a stronghold on large swathes of the World Wide Web.
    • They unilaterally decide what should and should not be allowed over Internet.

    Key features of a Web3

    • Immutable ecosystem, i.e., trust that people will download the digital product just as the original creator intended.
    • Enhanced transparency and security,
    • Quicker browsing performance,
    • Complete user anonymity and confidentiality,
    • Integrating cryptocurrency wallets with multiple blockchains,
    • Complete control over the content due to decentralization.

    Evolution of (world-wide) web

    • The Web most of us know today is quite different from originally imagined.
    • To understand this better, it’s helpful to break the Web’s short history into loose periods—Web 1.0 and Web 2.0.

    (1) Web 1.0: Read-Only (1990-2004)

    • The first inception of ‘Web 1.0’, occurred roughly between 1990 to 2004.
    • It was mainly static websites owned by companies, and there was close to zero interaction between users – individuals seldom produced content – leading to it being known as the read-only web.

    (2) Web 2.0: Read-Write (2004-now)

    • The Web 2.0 period began in 2004 with the emergence of social media platforms.
    • Instead of a read-only, the web evolved to be read-write.
    • Instead of companies providing content to users, they also began to provide platforms to share user-generated content and engage in user-to-user interactions.
    • As more people came online, a handful of top companies began to control a disproportionate amount of the traffic and value generated on the web.
    • Web 2.0 also birthed the advertising-driven revenue model.
    • While users could create content, they didn’t own it or benefit from its monetization.

    How is Web3 prospected to be?

    • The premise of ‘Web 3.0’ was coined by Ethereum co-founder Gavin Wood shortly after Ethereum launched in 2014.
    • Gavin put into words a solution for a problem that many early crypto adopters felt: the Web required too much trust.
    • That is, most of the Web that people know and use today relies on trusting a handful of private companies to act in the public’s best interests.

    Core ideas of Web3

    Although it’s challenging to provide a rigid definition of what Web3 is, a few core principles guide its creation.

    • Web3 is decentralized: instead of large swathes of the internet controlled and owned by centralized entities, ownership gets distributed amongst its builders and users.
    • Web3 is permission-less: everyone has equal access to participate in Web3, and no one gets excluded.
    • Web3 has native payments: it uses cryptocurrency for spending and sending money online instead of relying on the outdated infrastructure of banks and payment processors.
    • Web3 is secure: It operates using incentives and economic mechanisms instead of relying on trusted third-parties.

    Why is Web3 important?

    • Ownership: Web3 gives you ownership of your digital assets in an unprecedented way. Web3 allows for direct ownership through non-fungible tokens (NFTs).
    • Censorship resistance: The power dynamic between platforms and content creators is massively imbalanced.
    • Decentralized autonomous organizations (DAOs): As well as owning your data in Web3, you can own the platform as a collective, using tokens that act like shares in a company.

  • What is RNA Origami?

    rna

    This newscard is an excerpt of the original article published in The Hindu.

    Note: It appears to be too much biological. And suddenly out of our ease of understanding.

    What is Ribo Nucleic Acid (RNA)?

    • RNA is an important biological macromolecule that is present in all biological cells.
    • It is principally involved in the synthesis of proteins, carrying the messenger instructions from DNA, which itself contains the genetic instructions required for the development and maintenance of life.
    • In some viruses, RNA, rather than DNA, carries genetic information.
    • The type of RNA dictates the function that this molecule will have within the cell.
    • Aside from the coding region of messenger RNA (mRNA) molecules that will be translated into proteins, other cellular RNA elements are involved in different processes.

    What are RNA Origami?

    • RNA origami is the nanoscale folding of RNA, enabling the RNA to create particular shapes to organize these molecules.
    • It is an attempt to generate complex human-made RNA-based devices.
    • They are stable in cells, interact with other biomolecules, including other RNA and proteins, and enable unique applications, particularly in the context of gene regulation.

    Why are they used?

    So far there have been two approaches in RNA origami and both attempt to regulate the production of protein.

    (1) To achieve precise control of protein production

    • Self-inhibiting protein expression cassettes were made by installing a strong binding site for the expressed protein in its own gene.
    • Afterwards, RNA origami decorated with the same protein-binding sites was expressed in large excess.
    • In this way, the RNA origami serves as a protein-sponge that sequesters proteins in the cell and allows expression of the self-inhibited protein.
    • This approach helped to regulate several proteins simultaneously and turn on enzymatic pathways for improved product yields.

    (2) Using for gene editing

    • The RNA origamis were integrated in the small RNAs that guide CRISPR-Cas9 enzyme to target specific sequences in the DNA genome.
    • Its scaffolds were decorated with protein-binding sites capable of recruiting transcription factors.
    • By targeting the RNA scaffolds to promoter regions, the transcription factors activated gene expression.
    • Researchers have shown that the expression strength can be tuned by the orienting the scaffold and level of transcription factors recruited.
    • These multi-enzyme pathways could be controlled for high-yield production of the anti-cancer drug violacein.

  • Black Hole, Resolving the Mistry

    Black Hole

    Context

    • For the very first time, scientists noted that this observation of the Laser Interferometer Gravitational Wave (LIGO) observatories coincided with the measurements made by other telescopes that measured visual and electromagnetic signals.

    What is Black hole?

    • A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
    • Because no light can get out, people can’t see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.

    Black Hole

    What is the background?

    • LIGO Observations: In 2017, astrophysicists observed an unusual feat among the stars. The Laser Interferometer Gravitational Wave(LIGO)observatories recorded a signal which indicated that two massive and dense stellar bodies had merged to form a third body, likely a black hole.
    • Generation gravitational waves: In the process they gave off vibrations that quite literally shook the universe and its very fabric of space time.
    • Neutron stars: Scientists, piecing together evidence from complementary measurements, surmised that the event they had observed was of two neutron stars merging and forming a black hole and, in the process, giving off light.

    Black Hole

    What are the observations through telescopes?

    • The matter moving faster than light: An unusual jet of matter was observed that gave an illusion of travelling faster than light. These were all exciting phenomena observed for the very first time by telescopes and observatories.
    • Confirmation by Hubble Space Telescope: Now, using data that had been recorded by the Global astro metric Interferometer for Astrophysics (GAIA) spacecraft and Hubble Space Telescope instruments, scientists have confirmed that the above picture is correct. They have made it more precise and descriptive.
    • Seven times the speed of light: In a paper published in Nature, they describe measuring the “apparent speed” of the jet to be about seven times the speed of light.
    • Lorenz factor: They have also measured more accurately a factor called the Lorenz factor which scales with the actual speed of the particles in the jet. Unlike earlier estimates which placed this factor at about 4, the present paper estimates this factor to be over 40. This is because they measure the speed of the relativistic jet to be close to 0.9997c, where “c” is the speed of light.
    • Clarity about the source as neutron star in block hole generation: This resolves the earlier fuzziness about what the source was and puts the source clearly as massive neutron stars merging to give a black hole and throwing off relativistic jets of particles in the process.

    Black Hole

    Merging of Neutron stars

    • Born out of Supernova explosion: Neutron stars are stellar corpses, left behind after a star has undergone a supernova explosion and reached the end of its lifetime. They are extremely dense, containing more mass than the sun in a sphere that is a few tens of kilometre wide.
    • Produces fast moving material: This has been seen in many active galactic nuclei  galaxy centres that harbour black holes and binary star systems within our galaxy, where one of the stars is a black hole. “Mostly, black holes are responsible for producing such fast moving material

    Why present observations about black Hole are significant?

    • Estimating changing position of sky: The present measurements and observations made with GAIA data are extremely challenging. They amount to measuring the position of an object in sky coordinates. These authors measured a change in sky position one millionth the span of the full moon. Normally, if one were making these measurements from earth-based telescopes, it would require data from radio telescopes spaced apart by intercontinental distances.
    • VLBI technique: This technique is called Very Long Baseline Interferometry (VLBI) and was used in the earlier papers. “Here, the authors could beat VLBI in precision because they calibrated Hubble Space Telescope data with GAIA, which is a precision astrometry mission.
    • It’s an estimate not a measurement: the researchers used both their Hubble Space Telescope and GAIA optical position measurement along with the earlier VLBI position measurement to get a better estimate of the speed of the source and angle (viewing angle) with which it is travelling with respect to us on earth. This estimate requires plugging in equations of the special theory of relativity. “So, it is an estimate as opposed to a measurement.
    • Improvement in estimation: we have learnt that neutron star mergers can result in material moving with speeds as high as 0.9997c.Earlier results using Very Long Baseline Interferometry had pegged this value at about 0.938c. with the new results this lower limit has been improved. Even earlier, with VLBI, it was understood that it was a neutron star merger that produced such ultra-relativistic material. Before the VLBI results, there were several models that could replicate the observations.
    • Explanation using ultra realistic material: The observations could be explained both by ultra-relativistic material and non relativistic material, with some differences in assumptions. That study indicated that the observed gamma ray bursts were produced along with the ultra-relativistic material.

    Conclusion

    • Current discovery strengthens the hypothesis that such neutron star mergers are responsible for a class of gamma ray bursts. Gamma ray bursts are flashes of extreme gamma ray photons that release a huge amount of energy nearly 1047 They come from different galaxies in the universe and are observed here quite frequently.

    Mains Question

    Q. What is the neutron star and how the merger of two stars produces a black hole? How LIGO and Hubble space telescope are useful in demystifying the black Hole phenomenon?

  • The illusion of being faster than light: how a star problem was solved

    light

    Scientists have spotted something that appeared to be moving 7 times faster than the Speed of Light in a supernova like event.

    What is the news?

    • In 2017, astrophysicists observed an unusual feat among the stars.
    • The Laser Interferometer Gravitational-Wave (LIGO) observatories recorded a signal which indicated that two massive and dense stellar bodies had merged to form a third body, likely a black hole.
    • An unusual jet of matter was observed that gave an illusion of travelling faster than light.

    Can matter move faster than Light?

    • From the data, it appeared the jets of matter were moving seven times faster than light.
    • The researchers explain the reason behind the discrepancy is due to something called superluminal motion.
    • Since the jet of matter reaches Earth at the speed of light, the light it emits at later points has a relatively shorter distance, making it appear faster than it actually is.
    • After more calculations, astronomers found the real speed to be at least 99.7 percent of the speed of light (3 × 10^8 m / s).

    Crossing the speed of light: An illusion

    • The data of same incident has been recorded by the Global Astrometric Interferometer for Astrophysics (GAIA) spacecraft and Hubble (James Web) Space Telescope
    • Using it, scientists confirmed that the above picture is correct.

    How to assess it?

    • Scientists have also measured more accurately a factor called the Lorenz factor which scales with the actual speed of the particles in the jet.
    • Unlike earlier estimates which placed this factor at about 4, the present paper estimates this factor to be over 40.
    • This is because they measure the speed of the relativistic jet to be close to 9997c, where “c” is the speed of light.

    How are they observed?

    • Source is clearly as massive neutron stars merging to give a black hole and throwing off relativistic jets of particles in the process.

    Merging neutron stars: Faking to cross speed of light

    • Neutron stars are stellar corpses, left behind after a star has undergone a supernova explosion and reached the end of its lifetime.
    • They are extremely dense, containing more mass than the sun in a sphere that is a few tens of kilometre wide.
    • The observation of particles moving at seven times the speed of light is an illusion.
    • This happens in cases where a source moves (towards us) with a velocity that is very close to light’s velocity.
    • This has been seen in many active galactic nuclei — galaxy centres that harbour black holes — and binary star systems within our galaxy, where one of the stars is a black hole.
    • Mostly, black holes are responsible for producing such fast-moving material.

    How is this illusion created?

    • Normally, if one were making these measurements from earth-based telescopes, it would require data from radio telescopes spaced apart by intercontinental distances.
    • This technique is called Very Long Baseline Interferometry (VLBI) and was used in the earlier papers.

    Significance of this study

    • The significance of the paper is that now, we have learnt that neutron star mergers can result in material moving with speeds as high as 0.9997c.
    • Earlier results using Very Long Baseline Interferometry had pegged this value at about 0.938c.
    • And with the new results this lower limit has been improved.
    • Even earlier, with VLBI, it was understood that it was a neutron-star merger that produced such ultra-relativistic material.

  • Making India’s Quantum Cyberspace resilient

    Quantum

    Context

    • The Army has collaborated with industry and academia to build secure communications and cryptography applications. This step builds on last year’s initiative to establish a quantum computing laboratory at the military engineering institute in Mhow, Madhya Pradesh.

     What is mean by quantum computing?

    • Quantum computing is an area of study focused on the development of computer based technologies centered around the principles of quantum theory.
    • Quantum computing studies computation systems that make direct use of quantum-mechanical phenomena to perform operations on data.
    • Classical computers encode information in bits. Each bit can take the value of 1 or 0. These 1s and 0s act as on/off switches that ultimately drive computer functions.

    What is quantum Theory?

    • Quantum theory explains the nature and behavior of energy and matter on the quantum (atomic and subatomic) level. Quantum theory is the theoretical basis of modern physics.
    • The nature and behavior of matter and energy at that level is sometimes referred to as quantum physics and quantum mechanics.

    Quantum

    What is quantum computing laboratory that the Army has set up?

    • Two research centres: The Army has set up a quantum computing laboratory and a centre for artificial intelligence (AI) at a military engineering institute in Madhya Pradesh. The Army will get support from National Security Council Secretariat (NSCS).
    • Purpose of the quantum lab: To spearhead research and training in this key developing field. It said the Indian Army is making steady and significant strides in the field of emerging technologies
    • To Train personnel on the cyber warfare: Training on cyber warfare is being imparted through a state of the art cyber range and cyber security labs.
    • The Focus areas: Key thrust areas are quantum key distribution, quantum communication and quantum computing, among others.

    What is the rationale behind this development?

    • To provide facility centre for extensive and dedicated research: The two centres will carry out extensive research in developing transformative technologies for use by the armed forces.
    • To transform the current system of cryptography: Research undertaken by the Army in the field of quantum technology will help it leapfrog into the next generation of communication and transform the current system of cryptography to post-quantum cryptography.
    • Developing quantum resistant systems: With traditional encryption models at risk and increasing military applications of quantum technology, the deployment of quantum-resistant systems has become the need of the hour.
    • Vulnerable existing digital infrastructure: There is a need of upgrading current encryption standards that can be broken by quantum cryptography. Current protocols like the RSA will quickly become outdated. This means that quantum cyber attacks can potentially breach any hardened target, opening a significant vulnerability for existing digital infrastructure. Hack proofing these systems will require considerable investments.
    • To be in a League of nations in this sector: For example US: National Quantum Initiative Act has already allocated $1.2 billion for research in defence related quantum technology. China now hosts two of the world’s fastest quantum computers.

    Quantum

    India’s developments in this sector so far?

    • National Mission on Quantum Technologies and Applications: In 2019, the Centre declared quantum technology a “mission of national importance”. The Union Budget 2020-21 had proposed to spend Rs 8,000 crore on the newly launched National Mission on Quantum Technologies and Applications.
    • Successfully demonstrated a Quantum key Distribution (QKD) link: In February 2022, a joint team of the Defence Research and Development Organization and IIT Delhi successfully demonstrated a QKD link between two cities in UP  Prayagraj and Vindhyachal  located 100 kilometres apart.

    What are the challenges facing India?

    • Current capabilities are not sufficient: Currently, India has very few capabilities in developing advanced systems capable of withstanding quantum cyber attacks.
    • The china challenge: China’s quantum advances expand the spectre of quantum cyber attacks against India’s digital infrastructure, which already faces a barrage of attacks from Chinese state-sponsored hackers.
    • Dependence on Foreign hardware: India is heavily dependent on foreign hardware, particularly Chinese hardware, is an additional vulnerability.

    Quantum

    How India can make its cyberspace resilient?

    • Procuring quantum resistant mechanism from US: India must consider procuring the United States National Security Agency’s (NSA) Suite B Cryptography Quantum-Resistant Suite as its official encryption mechanism. The NSA is developing new algorithms for their cypher suite that are resistant to quantum cyber attacks. This can then facilitate India’s official transition to quantum-resistant algorithms.
    • Enhancing cryptographic standards: The Indian Defence establishment can consider emulating the cryptographic standards set by the US’s National Institute of Standards and Technology (NIST) which has developed a series of encryption tools to handle quantum computer attacks. It has developed a series of four algorithms to frame a post-quantum cryptographic standard.
    • Diplomatic partnerships in this sector: Diplomatic partnerships with other techno-democracies countries with top technology sectors, advanced economies, and a commitment to liberal democracy can help India pool resources and mitigate emerging quantum cyber threats.
    • Active participation in global avenues: Active participation in the Open Quantum Safe project a global initiative started in 2016 for prototyping and integrating quantum-resistant cryptographic algorithms.
    • Providing funds and encouragement: India must start its national initiatives to develop quantum-resistant systems. For this, the government can fund and encourage existing open-source projects related to post-quantum cryptography.
    • Start implementing the capabilities: The country should start implementing and developing capabilities in quantum-resistant communications, specifically for critical strategic sectors. QKDs over long distances, especially connecting military outposts for sensitive communications, can be prioritised to ensure secure communications whilst protecting key intelligence from potential quantum cyber attacks.
    • Establishing nationwide network: Establish a nationwide communication network integrated with quantum cryptographic systems, thereby protecting cyberspace from any cross-border quantum cyber offensive.

    Conclusion

    • The world is moving towards an era in which the applications of quantum physics in strategic domains will soon become a reality, increasing cyber security risks. India is getting there slowly but steadily. India needs a holistic approach to tackle these challenges. At the heart of this approach should be the focus on post-quantum cyber security.

    Mains Question

    Q.The world is moving towards an era in which applications of quantum physics in strategic domains will soon become a reality, increasing cyber security threats. In this context, what steps can India take to make its cyberspace resilient and quantum-resistant? Discuss.

  • What is Carbon Dating?

    carbon dating

    A Varanasi district court has rejected the plea to conduct carbon-dating of the disputed structure known to have been found inside the premises of the Gyanvapi mosque.

    What is Carbon Dating?

    • Carbon dating, also called radiocarbon dating is method of age determination that depends upon the decay to nitrogen of radiocarbon (Carbon-14).
    • This method was developed by the American physicist Willard F. Libby about 1946.
    • Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere.
    • The neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.

    How it works?

    • Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain.
    • Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.
    • Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.

    The half-life concept

    • Carbon-14 has a half-life of 5,730 ± 40 years—i.e., half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.
    • Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

    Its uses

    • It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.
    • The method is widely used by geologists, anthropologists, archaeologists, and investigators in related fields.

  • ISRO proposes Bharat Krishi Satellite Programme

    isro

    The Indian Space Research Organisation (ISRO) has proposed dedicated satellites for supporting the country’s agriculture sector.

    Bharat Krishi Satellite Programme

    • Minimum of two satellites are stipulated to guarantee adequate coverage of the entire agricultural area of the country.
    • They will aid a gamut of farm-related activities related to crop forecasting, pesticide application, irrigation, soil data, and generation of critical data related to drought.
    • The satellites will be owned by the Department of Agriculture and not by ISRO. The ISRO will provide the technical support.
    • An ‘Earth Observation Council’ be created for addressing the current deficiencies in earth observation capabilities and data utilisation.
    • Such a council can tackle shortcomings in this area in a centralised manner.

    Why need such program?

    Current deficiencies include:

    1. Discontinuity in earth observation missions
    2. Low utilisation of available remote sensing data
    3. Technology gaps and

    The Indian Space Research Organisation (ISRO) is developing a Next-Gen Launch Vehicle (NGLV), which will one day replace operational systems like the Polar Satellite Launch Vehicle (PSLV).

    What is the news?

    • PSLV, often dubbed the ‘trusted workhorse’, “will have to retire” one day, said ISRO chairman.

    What is NGLV?

    • NGLV will feature a simple, robust design that allows bulk manufacturing, modularity in systems, sub-systems and stages and minimal turnaround time.
    • Potential uses will be in the areas of launching communication satellites, deep space missions, future human spaceflight and cargo missions.

    What all modifications would be required?

    • In NGLV, ISRO is understood to be looking at a cost-efficient, three-stage, reusable heavy-lift vehicle with a payload capability of 10 tonnes to Geostationary Transfer Orbit (GTO).
    • NGLV will feature semi-cryogenic propulsion for the booster stages which is cheaper and efficient.
    • For that, at least 10 tonne capability to GTO is needed.
    • Correspondingly, the Low Earth Orbit (LEO) capability will be twice that.
    • However, payload capability will be lower when the rocket is reusable.
