Axiom Space has successfully launched its fourth private astronaut mission to the International Space Station, further accelerating commercial space exploration and international participation in orbital missions.
At a Glance
- Ax-4 launched four private astronauts to the ISS on June 25, 2025.
- The mission launched from Kennedy Space Center at 2:31 a.m. EDT.
- Crew members include Peggy Whitson (USA), Shubhanshu Shukla (India), Sławosz Uznański-Wiśniewski (Poland), and Tibor Kapu (Hungary).
- Astronauts will perform over 60 experiments during a 14-21-day stay.
- The mission supports Axiom’s plans to build a commercial space station by the late 2020s.
A Landmark Crew in Private Spaceflight
Axiom Space’s Ax-4 mission successfully lifted off early on June 25 aboard a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center, sending four private astronauts toward the International Space Station (ISS). The crew, commanded by veteran NASA astronaut Peggy Whitson, features several historic firsts: Shubhanshu Shukla became India’s first private astronaut in orbit, joined by Poland’s Sławosz Uznański-Wiśniewski and Hungary’s Tibor Kapu, both marking their nations’ first private orbital flights.
Docking with the ISS is expected approximately 28 hours post-launch, initiating a two- to three-week mission dedicated to advancing scientific knowledge critical to future space exploration and terrestrial healthcare.

Innovation in Space Research and Tourism
Ax-4 underscores Axiom Space’s strategic expansion in commercial space operations, supported by close collaboration with NASA. With seats costing approximately $70 million each—including intensive astronaut training—the mission demonstrates an increasing accessibility of space to private and international participants.
During their time aboard the ISS, the astronauts will undertake more than 60 distinct scientific experiments, notably focusing on healthcare innovations such as diabetes management. Experiments examining how insulin delivery is affected by microgravity could lead to significant improvements for diabetic care on Earth.
Expanding International Collaboration
Ax-4 symbolizes the growing global dimension of space exploration, emphasizing international cooperation and diverse participation in orbital missions. This mission notably extends space access to astronauts from nations historically underrepresented in human spaceflight, fostering global STEM engagement as highlighted by Reuters.
As NASA prepares to retire the ISS, Axiom Space’s ambition for a fully commercial orbital station continues to take shape. Ax-4 marks a key milestone toward this goal, with ongoing construction of initial modules anticipated to create the world’s first privately operated space station by the late 2020s.
This mission firmly positions Axiom as a leader in shaping the future of human activity in orbit, potentially transforming space travel and research for generations.
