An international crew of four is en route to the International Space Station (ISS) following a successful launch from Florida on Friday. NASA’s SpaceX Crew-11 mission lifted off at 11:43 a.m. EDT on August 1, 2025, from Launch Complex 39A at NASA’s Kennedy Space Center, carried to orbit by a Falcon 9 rocket.
The mission had been postponed by one day after the initial launch attempt on July 31 was scrubbed with just over a minute left in the countdown due to a storm cell violating weather constraints. However, conditions improved for the second attempt, allowing for a smooth liftoff. Onboard the Crew Dragon Endeavour spacecraft are NASA astronauts Zena Cardman (Commander) and Mike Fincke (Pilot), alongside JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui and Roscosmos cosmonaut Oleg Platonov. The crew is expected to dock with the ISS at approximately 3 a.m. EDT on August 2.
This flight marks a series of personal and programmatic milestones. For Commander Cardman, it is her first journey into space. She was originally assigned to the Crew-9 mission but was reassigned to make room for the return of the Starliner test flight astronauts. This is the fourth spaceflight for veteran astronaut Mike Fincke, who last visited the ISS aboard the Space Shuttle Endeavour. In a poetic turn of events, he returns to space aboard another craft named Endeavour. Both Fincke and Yui were previously slated to fly on Boeing’s Starliner, highlighting the dynamic nature of crew assignments in the current era of spaceflight. For Platonov, this is also his first spaceflight, secured through a seat-swap agreement between NASA and Roscosmos.
The Crew-11 mission is the 11th crew rotation flight operated by SpaceX for NASA’s Commercial Crew Program. The crew will spend six to eight months aboard the orbiting laboratory, conducting scientific research, technology demonstrations, and station maintenance. Upon their arrival, they will be greeted by the members of Crew-10, who will conduct a handover before returning to Earth.
The mission also showcased SpaceX’s continued advancements in reusability. The Crew Dragon Endeavour capsule is making its sixth trip to space, a new record for the spacecraft. It was the first Dragon to carry humans to orbit during the Demo-2 mission in 2020. NASA and SpaceX are working to certify the Dragon for up to 15 flights, and this mission is a key step in that process. According to reports, the vehicle has received upgrades to its heat shield and parachute systems.
The Falcon 9 first-stage booster, B1094, completed its third successful flight. Following stage separation, it performed a flawless landing at Landing Zone 1 (LZ-1) at Cape Canaveral Space Force Station, treating spectators on the Space Coast to a powerful sonic boom. This landing was particularly noteworthy as it was the 53rd and final planned use of LZ-1 for a SpaceX booster recovery. William Gerstenmaier, SpaceX’s Vice President of Build and Flight Reliability, confirmed that future landings will utilize Landing Zone 2 and new pads being developed at the launch complexes, in line with U.S. Space Force requirements.
The successful launch of Crew-11 reinforces the reliability of the NASA-SpaceX partnership, which has ensured continuous American access to the International Space Station for over five years. As Cardman, Fincke, Yui, and Platonov begin their long-duration stay, they will contribute to the vital scientific work being done in microgravity, furthering human knowledge for future exploration.
