Recent Achievements of ISRO (Indian Space Research Organisation)

• Chandrayaan-3 Mission: ISRO successfully landed the Vikram Lander near the Moon’s south pole, making India the first country to achieve this feat. 
  • The mission also deployed the Pragyan rover, which conducted on-site experiments, including the detection of sulfur and other elements.
• ISRO’s Space Farming Trial: ISRO tested the growth of lobia (cowpea) seeds in space as part of its bio-regenerative life support system experiments, paving the way for sustainable food production in space missions.
• Aditya-L1 Mission: India’s first solar observatory, Aditya-L1, was launched to study the Sun’s atmosphere, including the corona, solar winds, and magnetic storms. It marked a significant step toward space-based solar research.
• XPoSat: It is the second such space-based observatory after NASA’s Imaging X-ray Polarimetry Explorer (IPEX), launched in 2021. The two instruments on board XPoSat, called XSPECT and POLIX, began operating after launch.
• PSLV-C57/Orbital Launch of Singapore’s DS-SAR Satellite: The PSLV-C57 mission launched the DS-SAR satellite and six co-passenger satellites for Singapore, reaffirming ISRO’s reputation for cost-effective commercial satellite launches.
• Gaganyaan Preparations: ISRO completed critical tests for the Gaganyaan Human Spaceflight Programme, including a crew escape system test. The mission is scheduled for 2025, aiming to make India the fourth country to send humans into space.
• LVM3-M3 OneWeb India-2 Mission: ISRO launched 36 OneWeb satellites into Low Earth Orbit, completing OneWeb’s first-generation global satellite constellation. This further solidified ISRO’s position in the global satellite launch market.

Role of Private Sector in Space

• Satellite Manufacturing and Launches: Skyroot’s Vikram-S became the first privately built rocket launched in India in November 2022.
• Space-Based Applications: Startups like Pixxel are using satellites for earth imaging and data analytics, enabling services in agriculture, disaster management, and urban planning.
• Collaboration with ISRO: L&T and HAL partnered with ISRO for the Gaganyaan mission.
• Driving Innovation: Agnikul Cosmos is working on 3D-printed rocket engines to revolutionize launch systems.

Potential of India’s Space Sector

• Expanding Market Size: The global space economy is estimated to reach $1 trillion by 2040, and India’s share, currently at just 2%, has significant growth potential.
• Satellite Launch Services: PSLV has launched over 400 foreign satellites from 36 countries, earning ISRO substantial revenue.
  • Over 10 years, ISRO has had 34 launches, successfully sending up 121 satellites, 75 of them foreign: 18 (24%) were from the USA, 11 (15%) Canadian, 8 (11%) each from Singapore and Germany, and 6 (8%) from the UK.
• Commercial Space Ventures: With the advent of private players like Skyroot Aerospace and Pixxel, India is diversifying into small satellite launches, space-based imaging, and data analytics.
• Focus on Space Exploration: Chandrayaan-3’s success as the first mission to soft-land near the lunar south pole.
• Global Partnerships: ISRO-NASA’s NISAR satellite will study climate change and natural disasters.

Challenges Faced by the Indian Space Sector

• Budget Constraints: Despite global recognition, ISRO operates on a relatively small budget compared to agencies like NASA.
  • Example: NASA’s 2023 budget was $25 billion, while ISRO’s was approximately $1.6 billion.
• Technological Gaps: Limited expertise in heavy-lift rockets and advanced reusable technologies delays ambitious missions.
• Space Debris Management: Increasing satellite launches add to space debris, posing long-term challenges for orbital sustainability.
• Brain Drain: Many top scientists seek better opportunities abroad due to limited funding and incentives in India.
• Geopolitical Constraints: Global collaborations face challenges due to international sanctions and technology denial regimes like the MTCR (Missile Technology Control Regime).

Government Initiatives for Space and ISRO

• Formation of IN-SPACe: The Indian National Space Promotion and Authorization Center (IN-SPACe) facilitates private sector participation in space activities, ensuring policy and regulatory support.
• Indian Space Policy 2023: The policy defines roles for ISRO, IN-SPACe, and private players, focusing on commercialization and R&D, with ISRO focusing on strategic missions.
• Budget Allocations: India allocated about Rs. 12000 crore to the Department of Space in Budget 2023-24
• Launch of NSIL (NewSpace India Limited): NSIL commercializes ISRO’s technologies and satellite launches, expanding India’s footprint in the global space economy.
• Focus on Education and Innovation: Programs like Young Scientist Programme (YUVIKA) and collaboration with IITs and IISc promote space education and R&D in India.
