Indian astronaut in space after 41-year gap, on mission to ISS

Why in the News ?

On June 26, 2025, India marked a historic moment in its space exploration journey as Group Captain Shubhanshu Shukla became the first Indian astronaut to reach the International Space Station (ISS), as part of the Axiom Mission 4 (Ax-4). 

• The mission launched aboard a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Centre in Florida, U.S., and is being hailed as the revival of India’s human space programme after a 41-year hiatus since Rakesh Sharma’s flight in 1984.
• Shukla, the mission’s pilot, is accompanied by Commander Peggy Whitson (U.S.), Mission Specialist Sławosz Uznański-Wiśniewski (Poland), and Mission Specialist Tibor Kapu (Hungary). 
• The crew will spend 14 days aboard the ISS, conducting scientific experiments, outreach, and commercial activities. Shukla’s onboard message declared: “This is not the start of my journey to the ISS but the start of India’s human space programme.”
• This mission marks a new era of international collaboration, private sector engagement, and renewed ambition for India’s aspirations in space.

Background

India’s Human Spaceflight Legacy

India’s engagement with manned spaceflight began in 1984 when Wing Commander Rakesh Sharma, flying aboard the Soviet Soyuz T-11, became the first Indian in space. His iconic response, “Saare Jahan Se Achha,” to Prime Minister Indira Gandhi from space, became a part of Indian folklore.

• Since then, while India’s unmanned missions like Chandrayaan, Mangalyaan, and Aditya-L1  have advanced significantly, its human spaceflight programme has seen limited progress. 
• That trajectory began to change with the announcement of the Gaganyaan Mission in 2018, intended to send Indian astronauts (Gagannauts) to low Earth orbit aboard an Indian spacecraft developed by ISRO.
• However, delays due to the COVID-19 pandemic, technical challenges, and budgetary constraints meant Gaganyaan’s crewed launch was postponed, with the first human-rated flight now expected by 2026-27.

Rise of Private and International Collaboration

• In parallel, the emergence of private players like SpaceX and commercial space missions by companies like Axiom Space opened new avenues for international cooperation. 
• Axiom Space, a private U.S. company, is planning to build the first commercial space station and conduct ISS missions with international astronauts.
• India’s collaboration with Axiom for sending Shukla is an early example of public-private-international partnerships in human spaceflight, ahead of the full launch of Gaganyaan.

Feature: Mission Highlights and India’s Renewed Human Spaceflight Efforts

The Axe-4 Mission

• Launch Date: June 26, 2025
• Launch Vehicle: SpaceX Falcon 9
• Spacecraft: SpaceX Dragon
• Mission Duration: 14 days on the ISS
• Crew Members:
  • Commander: Peggy Whitson (U.S.)
  • Pilot: Group Captain Shubhanshu Shukla (India)
  • Mission Specialists: Tibor Kapu (Hungary), Slawosz Uznański (Poland)
• Objective: Scientific research, technology demonstrations, outreach, and commercial activities representing 31 countries.

India’s Representation on ISS

Shukla becomes the first Indian astronaut aboard the ISS, a significant milestone given that Rakesh Sharma’s mission in 1984 predated the station. His presence aboard the ISS represents:

• The resurgence of India’s human space ambition.
• A stepping-stone for ISRO’s future crewed missions.
• India’s integration into the global space exploration ecosystem.

Science Diplomacy and Commercial Engagement

• Axiom-4 is not just a spaceflight but a scientific and diplomatic event, bringing countries together in space-based research.
• India’s presence enables greater exposure to microgravity research, technology validation, and biological and materials science experimentation.
• It sets a precedent for commercial human spaceflight opportunities for Indian citizens in future missions.

Group Captain Shubhanshu Shukla’s Role

• A test pilot in the Indian Air Force, Shukla was selected through a rigorous training programme, which included collaborations with ISRO, NASA, and the Gagarin Cosmonaut Training Centre (Russia).
• His selection also adds to the credibility and confidence in India’s astronaut training pipeline for the upcoming Gaganyaan mission.

Challenges

Delays in India’s Indigenous Human Space Programme

• The Gaganyaan mission, initially planned for 2022, has been repeatedly postponed.
• Technical readiness for human-rated launch vehicles, environmental control systems, and re-entry modules is still under development.
• Budget constraints and a limited private sector ecosystem slow down progress.

Dependence on Foreign Agencies

• India’s use of foreign launch facilities and training modules for Shukla’s mission highlights gaps in domestic infrastructure.
• This dependence poses a strategic vulnerability in the long run if indigenous capabilities are not developed in parallel.

Absence of a Clear Long-Term Human Spaceflight Policy

While Gaganyaan is underway, India lacks an articulated long-term roadmap for human space exploration:

• Will India send astronauts to the Moon or Mars?
• Will there be an Indian space station?
• What role will India play in global efforts like the Artemis Accords?

Limited Private Participation

• While SpaceX and Axiom represent robust private innovation, India’s private space sector is still nascent.
• Despite reforms by IN-SPACe and NSIL, Indian startups face issues with funding, licensing, and R&D access.

Talent Drain and Need for Training Infrastructure

• Many Indian-origin scientists work at NASA, ESA, or SpaceX.
• India must build domestic astronaut training centres, simulator labs, and collaborative ecosystems with academia to retain talent and prepare for future space missions.

Way Forward

Accelerate Gaganyaan with Realistic Timelines

• Conduct all uncrewed missions and abort tests planned for Gaganyaan in a time-bound manner.
• Maintain safety as top priority while fast-tracking critical technologies like life support, avionics, escape systems, and re-entry heat shields.

Establish a National Human Spaceflight Strategy

• India needs a 20-year vision outlining:
  • Short-term: Gaganyaan success and follow-up missions.
  • Mid-term: Indian astronaut to the Moon via collaboration (e.g., Artemis).
  • Long-term: Indian-built space station and deep space missions.
• This strategy must align with broader national goals of science diplomacy, innovation leadership, and economic growth.

Strengthen Public-Private Partnerships

• Leverage missions like Ax-4 to incubate Indian startups in microgravity R&D, space tourism, and human-rated tech development.
• Encourage co-investment models with Indian private firms in astronautics, crew module design, and propulsion.

Invest in Training Infrastructure

• Establish a permanent astronaut training and bio-psychological research centre in India.
• Partner with ISRO, Indian Air Force, DRDO, and global space agencies to exchange trainers, data, and equipment.

Amplify Global Collaborations

• India should actively participate in international manned missions through the Artemis Accords, the BRICS Space Forum, and the UN COPUOS.
• Building trust, fostering interoperability, and sharing missions will make India a vital partner in the global space community.

Conclusion

Group Captain Shubhanshu Shukla’s journey aboard the ISS is more than a symbolic return to space after 41 years; it is a clarion call for India’s spacefaring ambitions in the 21st century. As space becomes the new arena of technological power, geopolitical influence, and commercial opportunity, India’s renewed commitment to human spaceflight must be strategic, inclusive, and forward-looking.
