NASA will provide coverage of the upcoming prelaunch and launch activities for the agency’s SpaceX Crew-4 mission sending astronauts to the International Space Station.

The launch is targeted for 5:26 a.m. EDT Saturday, April 23, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The Crew Dragon spacecraft, dubbed by Crew-4 as Freedom, is scheduled to dock to the space station at 6 a.m. Sunday, April 24.

Prelaunch activities, along with launch and docking will air live on NASA Television, the NASA app, and the agency’s website.

The Crew-4 flight will carry Mission Commander Kjell Lindgren, Pilot Bob Hines, and Mission Specialist Jessica Watkins, all of NASA, and Mission Specialist Samantha Cristoforetti of ESA (European Space Agency), to the space station for a science expedition in microgravity.

The mission is the fourth crew rotation to fly on a SpaceX Crew Dragon spacecraft and Falcon 9 rocket and the fifth SpaceX flight with NASA astronauts, including the Demo-2 test flight in 2020 to the space station, as part of the agency’s Commercial Crew Program.

NASA’s Commercial Crew Program has delivered on its goal of safe, reliable, and cost-effective transportation to and from the International Space Station from the United States through a partnership with American private industry. This partnership is changing the arc of human spaceflight history by opening access to low-Earth orbit and the International Space Station to more people, more science and more commercial opportunities. The space station remains the springboard to NASA’s next great leap in space exploration, including future missions to the Moon and, eventually, to Mars.
