The Crew-4 mission will launch to the International Space Station (ISS) no earlier than April 23, NASA said in a press release.

“NASA and SpaceX are now targeting no earlier than 5:26 am EDT [9:26 a.m. GMT] Saturday, April 23, for the launch of the agency’s Crew-4 mission to the International Space Station from NASA’s Kennedy Space Center in Florida,” the statement said Tuesday.

The date provides agencies with time to complete final pre-launch processing of the Crew-4 mission following the launch of Axiom Mission 1 to the ISS on April 8, the statement said.

NASA will conduct a flight readiness review on Friday that will focus on preparing SpaceX’s crew transport system, the ISS, and its international partners supporting the flight, the statement said.

If the launch is delayed to April 23, the team will have opportunities to launch on April 24 and 25 as well, the statement said.

The Crew-4 mission will carry NASA astronauts Kjell Lindgren, Bob Hines and Jessica Watkins, as well as European Space Agency astronaut Samantha Cristoforetti, to the ISS on the Falcon 9 rocket with the Crew Dragon capsule. The rocket will launch from NASA’s Kennedy Space Center in Florida.
