On Monday, July 14, 2025, NASA will broadcast live coverage of the undocking and departure of the Axiom Mission 4 (Ax-4) private astronaut mission from the International Space Station (ISS). This milestone event marks the conclusion of a nearly three-week mission that has advanced scientific research and international collaboration in space exploration. The four-member crew, aboard a SpaceX Dragon spacecraft, is scheduled to undock from the ISS’s Harmony module at approximately 7:05 a.m. EDT (4:35 p.m. IST), with a splashdown expected off the coast of California.
Mission Overview and Crew
Axiom Mission 4, launched on June 25, 2025, from NASA’s Kennedy Space Center in Florida, represents a significant step in commercial space exploration. The mission, a collaboration between NASA, Axiom Space, and SpaceX, carried a diverse crew to the ISS for a planned 14-day stay, which was extended to approximately 17 days. The crew includes:
- Commander Peggy Whitson, a former NASA astronaut and director of human spaceflight at Axiom Space, leading the mission with her extensive experience.
- Pilot Shubhanshu Shukla, an Indian Air Force Group Captain and the first Indian Space Research Organisation (ISRO) astronaut to visit the ISS, marking a historic milestone for India’s space program.
- Mission Specialist Sławosz Uznański-Wiśniewski, a project astronaut from the European Space Agency (ESA), representing Poland.
- Mission Specialist Tibor Kapu, part of the Hungarian to Orbit (HUNOR) program, representing Hungary.
This mission underscores a commitment highlighted by former U.S. President Donald Trump and Indian Prime Minister Narendra Modi to send an ISRO astronaut to the ISS, fostering international partnerships in space. The crew’s diversity reflects the global cooperation driving modern space exploration.
Scientific Achievements
During their time aboard the ISS, the Ax-4 crew conducted over 60 scientific experiments and two in-orbit STEM demonstrations, leveraging the station’s unique microgravity environment. Their research included studies on microalgae, the effects of prolonged spaceflight on human physiology, and innovative agricultural experiments, such as Group Captain Shukla’s work growing methi and moong seeds in space. These experiments aim to yield practical applications for Earth, from advancements in medical science to sustainable food production. The Dragon spacecraft will return with over 580 pounds of cargo, including NASA hardware and data from these experiments, which will further scientific discovery.
Departure Schedule and Coverage
NASA’s live coverage of the Ax-4 departure will begin at 4:30 a.m. EDT (2:00 p.m. IST) on July 14, 2025, with hatch closing, followed by the crew entering the spacecraft at 4:55 a.m. EDT (2:25 p.m. IST). Undocking coverage will start at 6:45 a.m. EDT (4:15 p.m. IST) on NASA+, as well as Axiom Space and SpaceX platforms, with the undocking event at 7:05 a.m. EDT. NASA’s broadcast will conclude approximately 30 minutes after undocking, when joint operations with Axiom Space and SpaceX end. Axiom Space will continue coverage of the Dragon’s re-entry and splashdown via their website (axiom.space/live) and SpaceX’s channels.
Viewers can access NASA’s coverage through NASA+, the NASA app, and the agency’s website, with additional viewing options on social media platforms. This comprehensive coverage ensures that space enthusiasts worldwide can witness this historic event.
Significance of Axiom Mission 4
Axiom Mission 4 is the fourth all-private astronaut mission to the ISS, highlighting the growing role of commercial entities in space exploration. By partnering with companies like Axiom Space and SpaceX, NASA is advancing its strategy to focus on deep space missions, such as Artemis, while leveraging low Earth orbit for research and commercial opportunities. The mission’s success demonstrates the potential for private companies to drive economic growth in the space industry, paving the way for future ventures.
Public response to Ax-4 has been overwhelmingly positive, with global audiences expressing enthusiasm for the mission’s achievements and the international collaboration it represents. The inclusion of astronauts from India, Poland, and Hungary marks a historic first for these nations, further emphasizing the ISS’s role as a global laboratory for scientific and technological innovation.
Looking Ahead
As the Ax-4 crew prepares to return to Earth, their mission’s legacy will endure through the data and insights gained from their experiments. The safe return of the crew and their cargo will mark another successful chapter in the partnership between NASA, Axiom Space, and international space agencies. For those eager to follow the event, NASA’s live coverage offers an exciting opportunity to witness the future of space exploration unfold.
