Dr. Mahalanabis: the man behind ORS no more
While Oral Rehydration Solution (ORS) as a simple, effective remedy for dehydration is known around the world, the physician who pioneered the treatment, Dr. Dilip Mahalanabis, passed away.

What is ORS?
- Oral rehydration therapy is a type of fluid replacement used to prevent and treat dehydration, especially due to diarrhea.
- It involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium.
- Oral rehydration therapy can also be given by a nasogastric tube.
About Dr. Mahalanabis
- Born on November 12, 1934 in West Bengal, Dr Mahalanabis studied in Kolkata and London.
- He joined the Johns Hopkins University International Centre for Medical Research and Training in Kolkata in the 1960s, where he carried out research in oral rehydration therapy.
- When the 1971 war broke out, millions of people from then East Pakistan took refuge in India.
- Clean drinking water and sanitation were problems at these refugee camps, and cholera and diarrhoea broke out among people anyway exhausted and dehydrated.
- Dr Mahalanabis and his team were working in one such camp at Bongaon.
- Stocks of intravenous fluids were running out, on top of which there weren’t enough trained personnel to administer the IV treatment.
How he discovered ORS?
- From his research, Dr Mahalanabis knew that a solution of sugar and salt, which would increase water absorption by the body, could save lives from Cholera.
- He and his team then prepared solutions of salt and glucose in water and began storing them in large drums, from where patients or their relatives could help themselves.
- The oral solution then consisted of 22 gm glucose (as commercial monohydrate), 3.5 gm sodium chloride (as table salt) and 2.5 gm sodium bicarbonate (as baking soda) per liter of water.
- This was the simplest formula, containing the minimum number of ingredients, previously found to be effective in severely ill patients with cholera.
His legacy
- While initially, the medical fraternity was septical, the WHO eventually adopted ORS as the standard method for treating cholera and other diarrhoeal diseases.
- Today, the WHO recommends a combination of sodium chloride, anhydrous glucose, potassium chloride and Trisodium citrate dihydrate as the ORS formula.
- In India, July 29 is observed as ORS Day.

Making India’s Quantum Cyberspace resilient
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.
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.
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.
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?
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:

Discontinuity in earth observation missions
Low utilisation of available remote sensing data
Technology gaps and
Absence of a streamlined mechanism for data processing and dissemination as required by the industry

Applications of space for agriculture

Next-Gen Launch Vehicle- NGLV to assume PSLV’s role
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.

Adopting Sustainable Space Technology
Context
- World Space Week this year is themed around ‘Space and Sustainability’. Among other things, the 2022 theme seeks to specifically inspire focus on the challenges the world faces to keep space safe and sustainable.
What is mean by Space?
- Space is an almost perfect vacuum, nearly void of matter and with extremely low pressure. In space, sound doesn’t carry because there aren’t molecules close enough together to transmit sound between them. Not quite empty, bits of gas, dust and other matter floats around “emptier” areas of the universe, while more crowded regions can host planets, stars and galaxies.
- From our Earth-bound perspective, outer space is most often thought to begin about 62 miles (100 kilometers) above sea level at what is known as the Kármán line. This is an imaginary boundary at an altitude where there is no appreciable air to breathe or scatter light. Passing this altitude, blue starts to give way to black because oxygen molecules are not in enough abundance to make the sky blue.
What is mean by Space sustainability?
- Space sustainability is ensuring that all humanity can continue to use outer space for peaceful purposes and socioeconomic benefit now and in the long term. This will require international cooperation, discussion, and agreements designed to ensure that outer space is safe, secure, and peaceful.
What necessitate the sustainable space technology debate?
- Mounting challenge of Space debris: Challenges are endless in both quantitative and qualitative terms, i.e., they are several and severe, ranging from satellite crowding and collision risk to space debris in the Low Earth Orbit (LEO).
- Ever increasing satellites: The sense of urgency around space sustainability is already skyrocketing—more than 80 countries currently contribute to the over 6,800 active satellites in orbit, of which many are used for both civilian and military purposes, as well as over 30,000 pieces of orbital debris.
- Militarization of space: Given the development of new and emerging space technologies, the rapid militarisation and securitisation of space, and the growing distrust amongst nations in the domain, space activity is only set to increase and acquire a more national security-oriented focus.
- Large scale Development of ASAT: This is already visible in several countries around the world. There has been a recent uptick in the development and testing of destructive anti-satellite (ASAT) weapons, with 26 tests in the past two decades conducted by the four countries that have access to these weapons (US, Russia, China, and India).
- Massive investment into military space capability: France, which is currently leading the European Council, has also invested several billion euros into military space capabilities, and regularly emphasises the security importance of space for other EU countries.
- Increasing Defence space commands: Australia set up its Defence Space Command in early 2022 to increase its strategic potential in space, and South Korea deployed a spy satellite to better monitor North Korea in June 2022, giving its military space plan a huge push.
- However, none of these countries have a sustainability provision in their defence space operations or programmes.
What are the challenges of Security and sustainability of Space?
- Dichotomy in Security and sustainability: Sustainability and security are two sides of the same coin, but as a result of this inherent dichotomy, they are often juxtaposed against each other.
- Keeping Security is the priority: The contrast between highly motivated and funded national security efforts and the relatively non-prioritised international engagements around space sustainability is an example of a larger trend of indifference towards sustainable development in favour of higher military spending.
- SDG on backburner: To substantiate this point, funding for the Sustainable Development Goals (SDGs) was adversely affected due to COVID-19 in 2021, and this reportedly dramatically pushed back progress on the SDGs, but the global military expenditure has consistently been on an upward incline and crossed the US$2 trillion mark for the first time in the same year.
- Securitization of space: The trade-off between security and sustainability can jeopardise sustainable development within a plethora of issue domains, thus, increasing the likelihood of exhausting limited resources. This in turn could exacerbate the risk of conflict due to the resulting scarce resources, ultimately creating a vicious cycle of securitisation and conflict.
- Rat race in Space : As a case in point, the incumbent space race has always been marked by competing security and commercial interests, which has resulted in a constant escalation of global government spending on space programmes to its record value of US$98 billion in 2021. Space sustainability, on the other hand, has only seen activity recently, and primarily in an international and voluntary set-up.
What regulations are needed for Sustainable Space?
- Prioritising peaceful use of space: A Working Group on the Long-term Sustainability of Outer Space Activities was set up by the Committee on the Peaceful Uses of Outer Space (COPUOS) in 2010, which has 95 UN member states taking part in it. The Group adopted a set of guidelines by consensus in 2019, although it failed to make these guidelines or any other regulations legally binding. It agreed to work over it for 5 years from 2022 onwards, but since the Group uses a consensus-based approach to reach agreements, it is difficult to expect more stringent or extensive regulatory frameworks to emerge from it.
- Consensus is difficult but necessary: Consensus-based approaches in multilateral forums, especially related to arms or other security objectives, often contrast with individual national security interests of its member states and have been criticised for their slow or ineffective progress.
- Convention on Certain Conventional Weapons: Another example of this is the Convention on Certain Conventional Weapons’ (CCW) Group of Government Experts (GGE) meetings on lethal autonomous weapons systems (LAWS), which have only produced a set of 11 non-binding guiding principles since deliberations around LAWS began in 2014.
- Space sustainable ratings should be developed: The World Economic Forum, for instance, introduced a new standard called the Space Sustainability Rating (SSR), in 2022, which aims to recognise, reward, and encourage space actors to design and implement sustainable and responsible space missions. It remains to be seen whether countries will respond favourably to tools like the SSR, which are based on a positive reinforcement model, to be more space sustainability-conscious.
Conclusion
- space sustainability is only at the cusp of becoming actionable. When space experts, intergovernmental organisations, or countries themselves conclude that sustainability should be a part of their space mandate, and when they devise possible methods to help achieve this, they cannot do so in a vacuum. Space sustainability should not become the political football like climate change.

Critical Minerals: Opprtunity for Aatmanirbharta in Energy security.
Context
- In his Independence Day address, Prime Minister Narendra Modi exhorted the country to pursue aatmanirbhar bharta in energy by focusing on clean energy technologies. Securing access to key critical minerals such as lithium, cobalt, nickel and rare earth metals is critical for building resilient and indigenous supply chains for clean energy technologies.
Background
- Concerns over the pricing and availability of oil and gas in the wake of the Ukraine crisis continue to fuel global policy debates on energy security. However, the fragility of clean energy supply chains obscures pathways for countries to reduce dependence on fossil fuel.
- Imported inflationary pressures through exposure to volatile oil and gas markets also pose risks to macroeconomic growth and stability, particularly for India, import dependent for around 85% of its oil and half of its gas needs.
What are Critical Minerals?
- Critical minerals are elements that are the building blocks of essential modern-day technologies, and are at risk of supply chain disruptions.
- These minerals are now used everywhere from making mobile phones, computers to batteries, electric vehicles and green technologies like solar panels and wind turbines.
- Based on their individual needs and strategic considerations, different countries create their own lists.
- However, such lists mostly include graphite, lithium, cobalt, rare earths and silicon which is a key mineral for making computer chips, solar panels and batteries.
- Aerospace, communications and defence industries also rely on several such minerals as they are used in manufacturing fighter jets, drones, radio sets and other critical equipment.
Why is this resource critical?
- As countries around the world scale up their transition towards clean energy and digital economy, these critical resources are key to the ecosystem that fuels this change.
- Any supply shock can severely imperil the economy and strategic autonomy of a country over-dependent on others to procure critical minerals.
- But these supply risks exist due to rare availability, growing demand and complex processing value chain.
- Many times the complex supply chain can be disrupted by hostile regimes, or due to politically unstable regions.
- They are critical as the world is fast shifting from a fossil fuel-intensive to a mineral-intensive energy system.
What are Rare Earth Metals?
- The rare earth elements (REE) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table plus scandium and yttrium.
- Rare earth elements are an essential part of many high-tech devices.
- They have a wide range of applications, especially high-tech consumer products, such as cellular telephones, computer hard drives, electric and hybrid vehicles, and flat-screen monitors and televisions.
- Significant defense applications include electronic displays, guidance systems, lasers, and radar and sonar systems.
- Rare earth minerals, with names like neodymium, praseodymium, and dysprosium, are crucial to the manufacture of magnets used in industries of the future, such as wind turbines and electric cars.
Applications of REMs in various fields:
- Electronics: Television screens, computers, cell phones, silicon chips, monitor displays, long-life rechargeable batteries, camera lenses, light-emitting diodes (LEDs), compact fluorescent lamps (CFLs), baggage scanners, marine propulsion systems.
- Defense Sector: Rare earth elements play an essential role in our national defense. The military uses night-vision goggles, precision-guided weapons, communications equipment, GPS equipment, batteries, and other defense electronics. These give the United States military an enormous advantage. Rare earth metals are key ingredients for making the very hard alloys used in armored vehicles and projectiles that shatter upon impact.
- Renewable Energy: Solar panels, Hybrid automobiles, wind turbines, next-generation rechargeable batteries, bio-fuel catalysts.
- Manufacturing: High strength magnets, metal alloys, stress gauges, ceramic pigments, colorants in glassware, chemical oxidizing agent, polishing powders, plastics creation, as additives for strengthening other metals, automotive catalytic converters
- Medical Science: Portable x-ray machines, x-ray tubes, magnetic resonance imagery (MRI) contrast agents, nuclear medicine imaging, cancer treatment applications, and for genetic screening tests, medical and dental lasers.
- Technology: Lasers, optical glass, fiber optics, masers, radar detection devices, nuclear fuel rods, mercury-vapor lamps, highly reflective glass, computer memory, nuclear batteries, high-temperature superconductors.
DO YOU KNOW?

Metals such as cadmium, lead are often used in manufacturing plastic and over time can enter coastal waters. These are acutely harmful for coastal wildlife and humans.Different kinds of plastic releases different kinds of metals that may release when exposed to water and UV lights.

What are the challenges in accessing Critical minerals?
- Deposits in geopolitically sensitive regions: Reserves are often concentrated in regions that are geopolitically sensitive or fare poorly from an ease of doing business perspective.
- Controlled production: A portion of existing production is controlled by geostrategic competitors. For example, China wields considerable influence in cobalt mining in the Democratic Republic of Congo through direct equity investments and its Belt and Road Initiative.
- Agreements in advance from outside: Future mine production is often tied up in off take agreements, in advance, by buyers from other countries to cater to upcoming demand.
A step taken by Indian government for sourcing strategic minerals
- For sourcing of strategic minerals, the Indian government established Khanij Bidesh India Limited (KABIL) in 2019 with the mandate to secure mineral supply for the domestic market.
What is Khanij Bidesh India Limited (KABIL)?
- Joint venture: A joint venture company namely Khanij Bidesh India Ltd. (KABIL) set up with the participation of three Central Public Sector Enterprises namely, National Aluminium Company Ltd.(NALCO), Hindustan Copper Ltd.(HCL) and Mineral Exploration Company Ltd. (MECL).
- Objective: The objective of constituting KABIL is to ensure a consistent supply of critical and strategic minerals to Indian domestic market. While KABIL would ensure mineral security of the Nation, it would also help in realizing the overall objective of import substitution.
Suggestions based on Council on energy environment and water (CEEW) to achieve the objective of KABIL
- Mapping out the domestic requirement: Figure out the mineral requirements of the domestic industry. This could best be accomplished by a task force which includes the ministries of power, new and renewable energy, heavy industry, and science and technology.
- Clear road map for indigenous manufacturing: Five year road maps with clear targets for deployment and indigenous manufacturing across clean energy applications would provide visibility to domestic investors. Assess the technology mix that would support this deployment. On this basis, determine the quantities of minerals necessary to support indigenous manufacturing.
- Better coordination between different stakeholders: Coordinate with the domestic industry to determine where strategic interventions by the government would be necessary for the purpose.KABIL could collaborate with industry to bolster its market intelligence capabilities for tracking global supply side developments.
- Preemptive agreements through KABIL for reliable supply: If conducive investment opportunities don’t exist KABIL should preemptively sign off take agreements with global mineral suppliers to secure future production. It could aggregate reliable supply of minerals for domestic requirements and sign back to back sales agreements with the domestic industry .Such large scale centralised national procurement could be done at preferential terms.
- Joint Investment In mining assets to mitigate investment risks: The government should jointly invest in mining assets with geostrategic partners. KABIL should make equity investments in mining jurisdictions that private sector investors may deem too risky. It should leverage government to government partnerships to mitigate investment risks. This could be done through joint investments with sovereign entities from geostrategic partners or private sector entities with expertise in specific geographies.
- Finding the alternatives: Technologies such as sodium ion batteries could reduce requirements for sourcing minerals from beyond India’s borders. It could also propose co development of such technologies with geostrategic partners.
- Developing policies on sustainable urban mining and recycling: Develop policies on urban mining aimed at recycling mineral inputs from deployments that have completed their useful life. These could help further reduce dependence on international sourcing.
Conclusion
- Besides Ukraine, other potential geopolitical flash points also exist against a backdrop of dwindling multilateral cooperation. India must act immediately and decisively to mitigate these risks to its energy security.

India’s Space economy
India’s space economy is likely to be worth nearly $13 billion by 2025, with the satellite launch services segment set to witness the fastest growth due to increasing private participation.

About the report
- The report is released by the Indian Space Association (ISpA) and Ernst & Young.
- It says that the growing demand for smaller satellites is set to boost satellite manufacturing in the country.
- It will attract global start-ups in the sector to help incubate space tech companies to India.
Key highlights
- India’s space economy was pegged at $9.6 billion in 2020 and is expected to touch $12.8 billion by 2025.
- In dollar terms, the satellite services and applications segment would be the largest with a turnover of $4.6 billion by 2025, followed by the ground segment at $4 billion.
- Satellite manufacturing stands at $3.2 billion and launch services at $1 billion.
- The launch services segment was pegged at $600 million in 2020 and is projected to grow at a compound annual growth rate of 13 percent to reach $1 billion by 2025.
Key drivers of this demand
- India has of over 100 space tech start-ups with investments in the segment touching $68 million in 2021.
- The availability of low-cost satellite launch vehicles coupled with mass production will lead to demand from customers around the world.
- Several companies are utilising cutting-edge technologies to develop innovative launch solutions in India.
Where does India stand in the global space market?
- As per SpaceTech Analytics, India is the sixth-largest player in the industry internationally having 3.6% of the world’s space-tech companies (as of 2021).
- US holds the leader’s spot housing 56.4% of all companies in the space-tech ecosystem.
- Other major players include UK (6.5%), Canada (5.3%), China (4.7%) and Germany (4.1%).
- The Indian Space Industry was valued at $7 billion in 2019 and aspires to grow to $50 billion by 2024.
Why does India matter in the global space-tech market?
- The country’s standout feature is its cost-effectiveness.
- India holds the distinction of being the first country to have reached the Mars’ orbit in its first attempt and at $75 million — way cheaper than Western standards.
Future prospects of India’s private ‘Space’

Ans. India may lead in space junk management
- Almost 60-odd start-ups had registered with the Indian Space Research Organisation (ISRO) this year.
- A majority of them were dealing in projects related to space debris management.
- As space becomes more congested with satellites, the technology would thus help in managing ‘space junk’ (debris of old spacecraft and satellites).
How is the private sector’s involvement regulated in India?
- In June 2020, the Union government announced reforms in the space sector enabling more private players to provide end-to-end services.
- The central idea was to bring forth a predictable policy and regulatory environment for them and additionally provide access to ISRO facilities and assets to improve their capacities.
(1) Establishment of IN-SPACe
- An announcement for the establishment of the Indian National Space Promotion and Authorisation Centre (IN-SPACe) was made.
- It was mandated the task of promoting, authorising and licensing private players to carry out space activities.
- As an oversight and regulatory body, it is responsible for devising mechanisms to offer sharing of technology, expertise, and facilities free of cost to promote non-government private entities (NGPEs).
- IN-SPACe’s Monitoring and Promotion Directorate oversees NGPE’s activities as per prescribed regulations and reports back in case any corrective actions or resolutions are required.
- ISRO shares its expertise in matters pertaining to quality and reliability protocols, documentation, and testing procedure through IN-SPACe’s ‘interface mechanism’.
(2) Establishment of NSIL
- Additionally, constituted in March 2019, New Space India Ltd (NSIL), is mandated to transfer the matured technologies developed by the ISRO to Indian industries.
- All of them are under the purview of the Ministry of Defence.
- Private sector’s involvement in the long term, as with other commercial sectors, is believed to help spur investment and expertise in the realm which is capital-intensive and demands high technology.
Where does India lack?

Ans. Undisputedly, it is the finances
- The US and Canada were the highest receivers of space-related investment in 2021.
- The US’s space budget was $41 billion in 2021, $23.3 billion of which was focused on NASA.
- India’s total budgetary allocation for FY2022-23 towards the Department of Space was ₹13,700 crore ($172 million).
- Further, as per Tracxn data, funding into the sector’s start-ups (in India) nearly tripled to $67.2 million on a year-over-year basis in 2021.

India’s Dark Sky Reserve
Context
- The union territory of Ladakh will host India’s first Dark Sky Reserve which will be set up in Hanle area in the next three months. The Dark Sky Reserve is being built as part of Ladakh’s high-altitude Changthang Wildlife Sanctuary.
What is Dark Sky Reserve (DSR)?
- Definition of Dark Sky Reserve: The International Dark Sky Association (IDSA) defines an international dark sky reserve (IDSR) as “a public or private land of substantial size (at least 700 km², or about 173,000 acres) possessing an exceptional or distinguished quality of starry nights and nocturnal environment, and that is specifically protected for its scientific, natural, educational, cultural heritage, and/or public enjoyment.
What is Core Area of Dark Sky Reserve?
- A dark sky reserve requires a “core” area that has clear sky without any light pollution, which can enable telescopes to see the sky in its natural darkness.
Why Ladakh is chosen as ideal location for DSR?
- Ladakh is ideal for long-term observatories and dark-sky sites because of its large arid area, high elevation, and sparse population, extreme cold and minimum temperature drops to minus 40 degree celcius.
- The Changthang wildlife Sanctuary, the DSR site is situated around 4,500 metres above sea level, which makes it a perfect host for telescopes.
Who is managing India’s DSR?
- The Department of Science and Technology and Indian Institute of Astrophysics (IIA) in Bengaluru are providing support for the facility. The IIA already manages the Indian Astronomical Observatory (IAO) complex in Hanle, Ladakh.
What are the International standards for DSR?
- International Dark Sky Association’s Recognition: The IDSA recognizes and accredits dark-sky areas worldwide, in three categories. The Mont Mégantic Observatory in Quebec is the first such site to be recognized (in 2007) as an International Dark Sky Reserve.
- Categorical Certification: Individuals or groups can nominate a site for certification to the International Dark Sky Association (IDSA). There are five designated categories, namely International Dark Sky parks, communities, reserves, sanctuaries and Urban Night Sky Places.
- Global Recognition: The certification process is similar to that of a site being awarded the UNESCO World Heritage Site tag or getting recognised as a Biosphere Reserve. Between 2001 and January 2022, there have been 195 sites recognised as International Dark Sky Places globally, the IDSA said.
- Dark Sky Park: IDSA recognized Natural Bridges National Monument in Utah as the world’s first International Dark Sky Park.
- Dark Sky Sanctuary: In 2015, the IDSA introduced the term “Dark Sky Sanctuary” and designated the Elqui Valley of northern Chile as the world’s first International Dark Sky Sanctuary. The Gabriela Mistral Dark Sky Sanctuary is named after a Chilean poet.
What is India’s objective with DSR?
- To promote AstroTourism: The primary objective of the proposed Dark Sky Reserve is to promote astronomy tourism in a sustainable and environment-friendly manner. Scientific methods will be used here to preserve the night sky from ever-increasing light pollution.
- To offer clear skies for observations: With metros, cities and peripheral areas experiencing light pollution and remaining constantly lit up, there are diminishing areas that offer a view of clear skies on cloudless nights.
- For training purpose: In the pilot phase, the Indian Institute of Astrophysics (IIA),has procured ten small and easy-to-handle telescopes and light-reflecting shields. IIA’s scientists and outreach experts will identify locals and train them to use these telescopes.
- Sky gazing and a boost for village economy: This will include basic sky gazing, identification of constellations, and locating the pole star, among others. These telescopes will be installed at the homestays, which is a popular option for tourist accommodation in Ladakh.
Conclusion
- The Dark Sky Reserve is likely to boost Astro tourism in India where there has been no such reserve. Once set up, the reserve will be the highest-located site in the country for infrared, gamma-ray, and optical telescopes.
