Indian Astronaut Mission to International Space Station
Source:The Hindu ↗
Why It Matters
This marks a major milestone in India's space endeavors, serving as a critical precursor to the indigenous Gaganyaan mission. The microgravity experiments conducted will enhance India's capabilities in space biology and human survival in space environments.
Summary
Indian astronaut-designate Group Captain Shubhanshu Shukla will embark on a historic journey to the International Space Station (ISS) aboard the commercial Axiom-4 (Ax-4) mission on May 29, 2025. Launching via a SpaceX Dragon spacecraft, he will become the first Indian to visit the ISS and the first Indian in space since Rakesh Sharma in 1984. Serving as a mission specialist, Shukla will conduct various microgravity experiments proposed by Indian researchers, including studies on space biology and food sprouting. This mission is expected to provide invaluable experience for ISRO's upcoming Gaganyaan human spaceflight program.
Key Points
- Group Captain Shubhanshu Shukla is set to fly to the International Space Station (ISS) on May 29, 2025, as part of the commercial Axiom-4 (Ax-4) mission.
- He will be the first Indian astronaut to visit the ISS and the first Indian to travel to space in 40 years, following Rakesh Sharma's historic flight in 1984.
- Shukla, an astronaut-designate for ISRO's Gaganyaan mission, will gain crucial spaceflight experience that will benefit India's upcoming indigenous human spaceflight program.
- The mission will launch from NASA's Kennedy Space Center in Florida using a SpaceX Falcon 9 rocket and a Dragon spacecraft.
- During his time on the ISS, Shukla will conduct several microgravity experiments proposed by Indian scientists, focusing on muscle regeneration, cyanobacteria, tardigrades, and India-centric food sprouting (green gram and fenugreek).

Prelims Trap
Rakesh Sharma was the first Indian astronaut to visit the International Space Station (ISS) in 1984.
Rakesh Sharma travelled aboard a Soviet Soyuz mission to the Salyut-7 space station, not the ISS. The ISS was not launched until 1998.
Static Concepts Connected
What are the key objectives and orbit details of ISRO's Gaganyaan mission?
- Core Objective: To demonstrate indigenous capability to undertake human spaceflight to Low Earth Orbit (LEO).
- Orbit & Duration: A 3-member crew will be launched to a 400 km LEO for a 3-day mission.
- Re-entry: Safe return to Earth by landing in Indian sea waters.
- Launch Vehicle: LVM3 (Launch Vehicle Mark-3), reconfigured with a Human Rated Crew Escape System.
Why are biological experiments conducted in microgravity environments like the ISS?
- Gene Expression: Microgravity induces physiological changes, revealing unique genetic and molecular responses not observable on Earth.
- Extremophile Studies: Organisms like tardigrades are studied to understand survival mechanisms (cryptobiosis) against cosmic radiation and vacuum.
- Life Support Systems: Algae and cyanobacteria are tested for future deep-space agriculture and closed-loop oxygen generation.
Cross-Topic Patterns
Commercial Space & Indo-US Space Ties
Ax-4 is a private mission (Axiom/SpaceX) facilitated by NASA-ISRO agreements, highlighting the shift from state-led spaceflight to commercial partnerships, aligning with India's signing of the Artemis Accords.
Extremophiles & Astrobiology
Testing tardigrades and cyanobacteria links space technology with fundamental biology, echoing past UPSC questions on extremophiles, cryptobiosis, and potential life-support systems.
