Indian astronaut Shubhanshu Shukla and the Ax-4 crew are set to undock from the International Space Station on July 14 after completing a record-setting private mission
Mission Extended: Why Ax-4 Stayed Longer Than Planned
Orbit Exit – Originally scheduled to return on July 10, the Ax-4 crew’s stay aboard the ISS was extended by four days due to weather and mission logistics, according to the European Space Agency. The new undocking time is set for July 14 at 7:05 a.m. ET (4:35 p.m. IST).

Launched on June 25 aboard a SpaceX Falcon 9 rocket, the crew docked with the ISS on June 26, ahead of schedule. The mission includes:
- Commander Peggy Whitson (USA)
- Pilot Shubhanshu “Shux” Shukla (India)
- Mission Specialist Slawosz Uznański-Wiśniewski (Poland)
- Mission Specialist Tibor Kapu (Hungary)
The delay allowed the crew to complete additional experiments, including studies on eye movement, neural coordination, and stress responses using VR headsets and neural caps. The team also captured stunning Earth imagery and connected with families during off-duty hours.
India in Orbit: Shukla’s Microgravity Experiments Break New Ground
Representing ISRO, Group Captain Shubhanshu Shukla conducted seven indigenous experiments and five under ISRO-NASA collaboration, making him the first Indian to enter the ISS on a private mission.
Key highlights include:
- Microalgae Deployment: Studying algae’s potential to produce food, oxygen, and biofuels for deep-space missions
- Sprouts Project: Investigating how microgravity affects germination and plant genetics across generations
- Voyager Displays Study: Assessing how spaceflight impacts eye movement and motor coordination
These experiments aim to improve life-support systems, biomedical research, and space agriculture, critical for missions like Gaganyaan and future lunar or Martian expeditions.
Shukla also interacted with ISRO Chairman V Narayanan, Prime Minister Narendra Modi, and Indian schoolchildren via ham radio, inspiring the next generation of space scientists.
What Ax-4 Means for India and Private Spaceflight
The Ax-4 mission marks a turning point in private astronaut missions, with Axiom Space reporting over 60 experiments from 31 countries, making it the most research-intensive private mission to date.
For India, Shukla’s participation signals:
- Global collaboration in space science
- Validation of ISRO’s astronaut training protocols
- Momentum for India’s commercial space sector
The mission also highlights the growing role of private companies like Axiom Space and SpaceX in democratizing access to low-Earth orbit. As Shukla and his crewmates prepare for splashdown in the Atlantic Ocean, their journey underscores the fusion of science, diplomacy, and human ambition.
Conclusion:
Shubhanshu Shukla’s return from the ISS is more than a homecoming, it’s a milestone for India’s space aspirations. As the Ax-4 crew undocks on July 14, their legacy will orbit far beyond.
