The fourth private mission to ISS is set to head to Station Wednesday morning at 8:22 AM ET, weather and technicals permitting. Weather offshore in the ascent corridor forced a scrub for Tuesday, due to unacceptable conditions on Falcon 9 and Crew Dragon’s path towards ISS.
The Mission
The mission—organized by Houston-based Axiom Space—represents a growing shift in space exploration: national pride and private enterprise, working hand in hand. It’s the first time astronauts from India, Poland, and Hungary will fly to the ISS, and the vehicle taking them there is no less historic. The Crew Dragon capsule, designated C213, is the final capsule SpaceX plans to build under its current production schedule. This is its first flight.
C213’s official name has not been released to the public, and tradition calls for the first crew to fly it to also name the spacecraft. Expect to hear that name prior to the launch tomorrow.
The Crew
Leading the crew is Peggy Whitson, a name already etched into American spaceflight history. A retired NASA astronaut and now Axiom’s Director of Human Spaceflight, Whitson has spent more time in orbit than any other American—675 days in total. She’s flown on both the Space Shuttle and Soyuz, and this marks her fifth trip to space. Despite all that experience, she said the diversity and ambition of this mission makes it feel new again.
“It’s an exciting time to be part of space exploration,” Whitson told reporters before launch. “This is about opening access, building partnerships, and pushing science forward.”
Sitting beside Whitson in the cockpit is Indian Air Force Group Captain Shubhanshu Shukla, making history as the first Indian astronaut to visit the ISS. At 39, Shukla is a veteran test pilot, having flown everything from MiG-21s to Su-30s. He was part of India’s astronaut corps for the upcoming Gaganyaan program, and this mission is seen as a critical stepping stone for India’s human spaceflight ambitions.
For Shukla, the symbolism runs deep. “To represent India in this way is both humbling and thrilling,” he said. He’s carrying with him a suite of Indian microgravity experiments—including studies on tardigrade survival, plant growth, and stem cell behavior—that could lay the groundwork for India’s long-term research goals in orbit.
Joining them is Sławosz Uznański, a Polish engineer and the first representative of his country in space since 1978. Back then, it was Mirosław Hermaszewski aboard a Soviet Soyuz. This time, it’s Uznański flying under the banner of the European Space Agency as a mission specialist. A former CERN engineer and ESA reserve astronaut, Uznański’s path to space was defined more by science than by spectacle. His role on Ax-4 emphasizes research, including a number of biomedical and Earth-monitoring experiments designed by Polish institutions.
Hungary, too, is returning to space after a four-decade absence. Tibor Kapu, an engineer selected under the Hungarian government’s HUNOR program, became only the second Hungarian to ever fly in space. He beat out nearly 250 applicants for the role. The first, Bertalan Farkas, flew aboard a Soviet Soyuz spacecraft in 1980.
Kapu’s mission is both technical and symbolic. “This is not just a mission for Hungary,” he said before launch. “It’s for all the small nations looking toward the stars and asking if they can be part of the next chapter.”
Together, the Ax-4 crew brings four national flags and a shared sense of purpose to orbit. Their flight to the ISS will last roughly 14 days and includes more than 60 research projects from 31 countries—an international science effort that spans biology, medicine, technology, and Earth science. The scope is ambitious: studies on glucose regulation that could impact diabetes treatment, advanced materials testing in zero gravity, and new methods for monitoring joint health in long-duration missions.

This is a Return to Landing Site mission, meaning Booster B1094 will be landing at Cape Canaveral Space Force Station on Landing Zone 1, the site of the old LC-13. A sonic boom will herald the arrival of the booster to the Space Coast.

The Weather
The 45th Weather Squadron on Space Launch Delta 45 released their L-1 (one day prior to launch) forecast for Axiom 4: 95% go at the launch site, but a high risk in the ascent corridor.
This necessitated a scrub, with events now moved to NET Wednesday, June 11th. The weather on Wednesday is somewhat worse at the launch site: a 1-in-5 chance of a weather-related scrub at the launch site (80% GO) and only slightly better conditions on the spacecraft’s path towards orbit.
Why This Matters
If something goes wrong during launch (engine failure, system anomaly, etc.), the crew capsule—SpaceX’s Crew Dragon—has the ability to abort and separate from the rocket at any point in the ascent. After separation, it parachutes down into the Atlantic Ocean.
That means the entire flight path up the East Coast, from Florida to somewhere past Ireland, must have acceptable weather conditions for:
- Rescue operations (search-and-rescue boats and helicopters need to reach the crew quickly)
- Survivability (waves, wind, and visibility must not endanger the capsule or the astronauts)
- Recovery asset safety (ships and aircraft can’t operate in dangerous storms)
Even if the launch pad weather is perfect, bad weather anywhere along the ascent corridor can delay a launch. NASA and SpaceX have multiple pre-designated splashdown zones, and each one must meet strict criteria for wind speeds, wave heights, lightning risk, and cloud cover during launch.
Privately Operated Missions: The Way of the Future
Axiom Space has carved out a unique model for missions like this. Unlike traditional government-led flights, the Ax-4 mission is privately operated and commercially funded, with participating countries contributing financially or technically in exchange for astronaut slots. This hybrid approach allows smaller spacefaring nations to engage in human spaceflight without launching their own rockets or building their own stations.
The capsule they’re riding in—Crew Dragon C213—is another milestone. It’s the fifth and final new Dragon that SpaceX plans to produce under its current human spaceflight program. From here on, the company will rely on reusing existing vehicles. That C213 is debuting with such a historic, multicultural mission underscores the symbolic weight of the moment.
Axiom Space is also developing its own privately-owned commercially operated space station. Axiom Station is currently under construction. The first module, the Payload Power Thermal Module (PPTM), are scheduled to be launched to the International Space Station (ISS) no earlier than 2027, according to Axiom Space and Wikipedia. The Habitat One (Hab-1) module is expected to launch no earlier than 2028. The Axiom Station is planned to be a commercial space station, with Axiom Space aiming to start operating a free-flying platform as early as 2028.
Ax-4 Flight Plans
Once aboard ISS, the crew will be integrated into daily life on the station, conducting experiments while also taking time for public outreach and cultural exchange. Whitson noted that the crew has trained extensively not just in operations but in working across language and cultural lines—an increasingly relevant skill set in today’s globalized approach to space.
The crew’s return is scheduled for late June after a roughly two-week stay aboard the orbiting outpost, though the exact splashdown date will depend on weather and recovery conditions in the Pacific. SpaceX recently moved crew landing operations to the Pacific offshore from southern California due to finicky conditions here in Florida.
