Crew-4 is the fourth crew rotation flight to the International Space Station as part of NASA’s Commercial Crew Program. The SpaceX Crew Dragon capsule is targeted to launch atop the company’s Falcon 9 rocket from Launch Complex 39A to the space station on Wednesday, April 27, at 3:52 a.m. EDT.

Earlier on Tuesday, April 26, NASA Administrator Bill Nelson and senior NASA leadership addressed members of the media during a briefing held at the agency’s Kennedy Space Center in Florida for NASA’s SpaceX Crew-4 mission, now less than a day away.

“Flying safely with crew means that you’ve got to do it one step at a time,” said Kathryn Lueders, associate administrator, Space Operations Mission Directorate, NASA Headquarters. “So, tomorrow morning, we’re hoping that you’ll get to see a really, really beautiful step, and we’ll get our crew safely to orbit.”

Crew-4 is the fourth crew rotation flight of a U.S. commercial spacecraft under the agency’s Commercial Crew Program. The mission will send NASA astronauts Kjell Lindgren, Robert Hines, and Jessica Watkins, and ESA (European Space Agency) astronaut Samantha Cristoforetti to the International Space Station for a rotation science expedition, living and working as part of what is expected to be a 7-member crew.

Lindgren and Hines were assigned to the Crew-4 mission in February 2021 and began working and training on SpaceX’s next-generation human spacecraft and for their stay aboard the space station. Cristoforetti was assigned to the mission in March 2021 and Watkins was added as the fourth crew member in November 2021.

The Crew-4 mission continues NASA’s efforts to restore and maintain American leadership in human spaceflight. Regular commercial crew rotation missions enable NASA to continue the important research and technology investigations taking place aboard the station. Such research benefits people on Earth and lays the groundwork for future exploration beyond low-Earth orbit, starting with the agency’s Artemis missions, which includes landing the first woman and person of color on the lunar surface.

The SpaceX Falcon 9 rocket and Crew Dragon spacecraft, which the crew has named Freedom, are scheduled to lift off at 3:52 a.m. EDT on Wednesday, April 27. Just over 17 hours after launch, the crew is expected to arrive at the orbiting laboratory. Docking is planned for approximately 8:15 p.m. EDT on Wednesday, April 27.

Weather officials with the U.S. Space Force’s 45th Weather Squadron are predicting an 90% chance of favorable weather conditions for launch – this is derived from Falcon 9 Crew Dragon launch weather criteria. The primary weather concerns are cumulus cloud and flight through precipitation rules.

For more than 21 years, humans have continuously lived and worked aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies that enable us to prepare for human exploration to the Moon and Mars. The station’s design requires humans living aboard to maintain it, operate it, and upgrade it; thus, International Space Station operations, including commercial resupply and commercial crew, are essential to the mission.

Live coverage of launch preparations and liftoff will begin at 12 a.m. EDT on Wednesday, April 27, on NASA Television, the NASA app, and the agency’s website.

Station Crew Awaits Ax-1 Departure and Crew-4 Launch

International Space Station Configuration. Six spaceships are parked at the space station including the SpaceX Dragons Endurance and Endeavour; the Northrop Grumman Cygnus space freighter; and Russia's Soyuz MS-21 crew ship and the Progress 79 and 80 resupply ships.

The integrated NASA, Axiom Space, and SpaceX teams have agreed on a plan for the Axiom Mission 1 (Ax-1) crew to undock from the International Space Station at 8:35 p.m. EDT Saturday, April 23, for a splashdown off the coast of Florida about 1:46 p.m. Sunday, April 24. The decision was made based on the best weather for splashdown of the first private astronaut mission to visit the International Space Station and the return trajectory required to bring the crew and the SpaceX Dragon Endeavour spacecraft back to Earth safely.

NASA will provide live coverage of departure activities beginning at 6:15 p.m. Saturday, April 23, with hatch closure targeted for 6:30 p.m. Coverage will resume at 8:15 p.m. for the undocking. Teams will continue to monitor weather at the splashdown sites prior to undocking to ensure conditions are acceptable for a safe recovery of the Ax-1 astronauts and Dragon spacecraft.

NASA and Axiom mission planning prepared for the possibility of additional time on station for the private astronauts, and there are sufficient provisions for all 11 crew members aboard the space station. The Ax-1 crew continues to work through previously planned mission activities. The Ax-1 crew and Dragon spacecraft remain healthy.

The departure of Dragon Endeavour from the space station will clear the docking port for the arrival of Dragon Freedom and NASA’s SpaceX Crew-4 astronauts. The earliest potential launch opportunity for the Crew-4 mission is 4:15 a.m. Tuesday, April 26, with additional opportunities Wednesday, April 27, and Thursday, April 28. These launch opportunities are undergoing a more detailed program review to ensure they align with integrated operational timelines. The teams want to provide a two-day gap after Ax-1 return for data reviews from splashdown and to prepare for the Crew-4 launch, including the staging of recovery assets.

The Crew-4 astronauts spent last night at the Kennedy Space Center in Florida rehearsing the countdown to their launch inside the SpaceX Dragon Freedom, the company’s newest crew ship. Overnight, Crew-4 Commander Kjell Lindgren, Pilot Robert Hines with Mission Specialists Jessica Watkins and Samantha Cristoforetti, put on their pressure suits and entered their vehicle conducting a successful dry dress rehearsal. The Falcon 9 rocket, with the Freedom perched atop, stands at Launch Complex 39A.

Expedition 67 crewmates Raja Chari and Tom Marshburn, who are also the SpaceX Crew-3 commander and pilot respectively, spent a little time on Wednesday with their upcoming departure activities. The pair, along with Kayla Barron of NASA and Matthias Maurer of ESA, will wait for the arrival of their Crew-4 replacements before returning to Earth a few days later inside the Dragon Endurance vehicle. The four astronauts had a light-duty day on Wednesday scheduling in some housecleaning tasks.

Over in the Russian segment of the station, cosmonauts Oleg Artemyev and Denis Matveev wrapped up their post-spacewalk activities today stowing their tools and discussing the excursion with specialists on the ground. The duo kicked off a series of spacewalks on April 18 to configure the European robotic arm for operations on the Nauka multipurpose laboratory module. Roscosmos Flight Engineer Sergey Korsakov started his day with electronics and communications maintenance before studying future spacecraft and robotic piloting techniques in the afternoon.
