SpaceX Delivers Four Astronauts to International Space Station Just 15 Hours After Launch
On August 1, 2025, SpaceX successfully launched its Crew-11 mission from NASA's Kennedy Space Center in Florida at 11:43 a.m. EDT, propelling four astronauts toward the International Space Station (ISS). This mission's Dragon capsule, named Endeavour, achieved a remarkably fast rendezvous and docked autonomously at the ISS’s Harmony module approximately 15 hours later, around 3 a.m. EDT on August 2.
Crew-11 Astronauts and Their Mission
The Crew-11 team includes:
NASA astronauts Zena Cardman (Commander) and Mike Fincke (Pilot)
Kimiya Yui from the Japan Aerospace Exploration Agency (JAXA)
Russian Roscosmos cosmonaut Oleg Platonov (Mission Specialists)
This international crew will spend six months aboard the ISS conducting scientific research. Their work involves experiments related to plant cell division, the effects of microgravity on viruses targeting bacteria, and generating human stem cells and essential nutrients on demand.
Swift and Efficient Journey
SpaceX’s Falcon 9 rocket powered the Dragon capsule on a nine-minute ascent into orbit.
The spacecraft flew autonomously, with the crew having manual control capability if needed.
Docking at the ISS was executed smoothly and ahead of schedule, shortening the transit time compared to previous missions that took up to 39 hours.
Significance and Context
Crew-11 marks the 12th crewed mission flown to the ISS by SpaceX under NASA’s Commercial Crew Program.
This rapid transit highlights advancements in crewed spaceflight operations, reducing time astronauts spend in transit and increasing mission efficiency.
The arrival temporarily raises the ISS crew size to 11 until the outgoing Crew-10 members depart.
Next Steps for the Crew
After docking, the astronauts will settle into the station, offload cargo, and begin their planned scientific operations. A welcome ceremony took place shortly after their arrival.
