India’s Historic Space Mission: Shubhanshu Shukla’s Ax-4 Journey to ISS
Shubhanshu Shukla’s Space Journey: 25 June 2025 will forever be etched in golden letters in India’s space history. Former Indian Air Force test pilot and astronaut Shubhanshu Shukla embarked on his maiden spaceflight from Florida’s Kennedy Space Center as part of SpaceX’s Ax-4 mission. This is a historic achievement for India, showcasing the nation’s scientific and technological advancements on the global stage.
SpaceX’s Falcon-9 rocket successfully launched the Crew Dragon spacecraft into Earth’s orbit. The next critical phase of the mission is docking with the International Space Station (ISS). Operated by American private space company Axiom Space, the mission includes astronauts from India, the United States, Hungary, and Poland. Over the course of 14 days, Shubhanshu and his team will conduct scientific experiments in zero gravity.
This mission not only marks a new chapter in India’s space journey but also signals the country’s readiness to take on a leading role in global space research.
Ax-4 Mission: India’s Entry into Private Spaceflight
The Ax-4 mission is the fourth private mission by Axiom Space – a groundbreaking step in the realm of space research and tourism. Operated in collaboration with NASA and SpaceX, it represents international cooperation. The astronauts participating in the mission are:
- Commander: Peggy Whitson – A seasoned NASA astronaut who has led several missions.
- Mission Pilot: Shubhanshu Shukla – Former test pilot of the Indian Air Force and the first astronaut representing India in such a mission.
- Mission Specialist: Sławosz Uznański-Wniveski – Astronaut from Poland.
- Mission Specialist: Tibor Kapu – Astronaut from Hungary.
Objectives of Ax-4 Mission:
- Promote scientific research.
- Encourage private spaceflight.
- Strengthen international cooperation.
India’s participation in this mission is not only a technological achievement but also a milestone in global space diplomacy. It demonstrates that India is now ready to be a stakeholder in private space ventures.
Falcon-9 and Crew Dragon
SpaceX’s Falcon-9 rocket is renowned worldwide for its reliability and reusability. Within minutes of launch, the rocket’s first stage landed back on Earth successfully – a significant stride towards cost-effective space travel.
Crew Dragon spacecraft is a state-of-the-art vehicle, fully automated but equipped for manual override in case of emergencies. Key features of the spacecraft include:
- Advanced life support systems: Ensures the safety of astronauts.
- Avionics: Cutting-edge technology for navigation and communication.
- Propulsion system: Allows precise maneuvering and orbital adjustment.
After launch, Crew Dragon entered low Earth orbit and is now heading toward the ISS. NASA has humorously referred to this phase as a “cat-and-mouse chase,” as the spacecraft must synchronize its speed and position with the ISS orbit.
India’s Pride: Shubhanshu Shukla
Shubhanshu Shukla, affectionately called “Shux” by his team, is a highly experienced test pilot from the Indian Air Force. He has flown aircraft like the MiG-21, Su-30, and several other fighter jets. His technical prowess, calm decision-making, and disciplined work ethic made him an ideal candidate for the Ax-4 mission.
Shubhanshu’s Role in the Mission:
As mission pilot, Shubhanshu’s responsibilities are critical to the mission’s safety and success:
- Monitoring trajectory: Ensuring Crew Dragon remains on the correct path.
- Manual control: Taking over systems manually in emergencies.
- System monitoring: Overseeing avionics, propulsion, and life-support systems.
- Collision avoidance maneuvers (CAM): Assisting in avoiding potential collisions during docking.
- Emergency decisions: Being ready for crucial decisions like launch aborts.
His role is akin to that of a supervisor and backup operator, acting as a safety net for Crew Dragon’s automated systems. His technical skills and dedication have brought pride to India on the world stage.
Docking: The Ultimate Test of Technical Precision
Once in Earth’s orbit, the next destination for Crew Dragon is docking with the ISS. This is an extremely complex process that demands millimetre-level precision. According to NASA, it will take over 24 hours for Crew Dragon to reach and dock with the ISS.
Docking Process:
- Orbital synchronization: Crew Dragon must match the ISS’s orbit, which is 400 km above Earth and moving at 27,600 km/h.
- Automated navigation: Sensor and laser-based systems will target the ISS’s Harmony Module’s space-facing port.
- Soft capture: The spacecraft will gently attach to the ISS.
- Hard capture: Mechanical locking systems will secure the connection.
- Pressurisation and hatch opening: After docking, pressure will be equalized, allowing astronauts to enter the ISS.
Docking Schedule: 26 June 2025, 10:00 PM IST.
NASA and SpaceX’s Mission Control Centres will be monitoring the process live.
Why is Docking Important?
Docking is a process where even a minor error can jeopardize the mission. It is not just a technical challenge but also a demonstration of coordination between astronauts and mission control.
Post-Docking: 14 Days of Scientific Research
After docking, Shubhanshu and his team will enter the Harmony Module of the ISS. For the next 14 days, they will perform various scientific experiments in zero gravity. These include:
- Biological research: Studying the effects of space on the human body, such as impacts on muscles and bones.
- Material science: Developing and testing new materials for both space and Earth applications.
- Fluid dynamics: Understanding how liquids behave in microgravity, vital for space technology.
- Earth observation: Collecting climate and environmental data crucial for Earth’s future.
These experiments will provide essential data for future missions to the Moon and Mars and contribute to scientific progress on Earth.
A Proud Moment for India
Shubhanshu Shukla’s flight is a historic achievement for India. This mission represents the growth of India’s space programme and proves that the country is ready to partner in private space missions.
Contribution to Global Space Diplomacy:
India’s involvement in the Ax-4 mission brings a new dimension to global space diplomacy, symbolising collaboration between India, the United States, and European nations.
Inspiration for Youth:
Shubhanshu’s story is an inspiration for India’s youth. His hard work, technical brilliance, and determination demonstrate that no goal is unattainable. His achievement will motivate young Indians to pursue careers in science, technology, and space exploration.
