In less than an hour (12:34 a.m. EST), the SpaceX Falcon 9 rocket, with Endeavour atop, will lift off from Kennedy Space Center’s Launch Complex 39A in Florida for NASA’s Space X Crew-6 mission to the International Space Station.

The mission is the sixth crew rotation flight of a Dragon spacecraft, carrying NASA astronauts Stephen Bowen and Warren Hoburg, who will serve as spacecraft commander and pilot, respectively, and UAE (United Arab Emirates) astronaut Sultan Alneyadi and Roscosmos cosmonaut Andrey Fedyaev, who will serve as mission specialists.

The crew will dock Endeavour to the forward port on the space station’s Harmony module about 24.5 hours after liftoff. Dragon is scheduled to dock to the space station at approximately 1:17 a.m. EST on Friday, March 3.

Later this month, the four SpaceX Crew-5 astronauts currently on the space station will enter the Dragon Endurance spacecraft and undock from Harmony’s space-facing port for a parachute-assisted splashdown off the coast of Florida. Endurance Commander Nicole Mann, Pilot Josh Cassada, and mission specialists Koichi Wakata and Anna Kikina have been living and working on the space station since Oct. 6, 2022.

Crew-6 is scheduled for a long-duration stay of up to six months aboard the space station, conducting science and maintenance before returning to Earth. Follow along here on the blog or tune in to the live broadcast on NASA Television and the agency’s website.

Weather at Kennedy Space Center Remains Positive for Crew-6 Launch

Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron continue to predict a 95% chance of favorable weather conditions for NASA’s SpaceX Crew-6 launch from Kennedy Space Center in Florida, with the flight through precipitation rule serving as the primary weather concern.

Liftoff, from historic Launch Complex 39A, is slated for 12:34 a.m. EST Thursday, March 2. Stay with us as the countdown continues; we’ll keep you updated on the key milestones throughout this important mission. Watch NASA’s live broadcast on NASA Television and the agency’s website.

Seated inside SpaceX’s Dragon Endeavour, awaiting launch, are NASA astronauts Commander Stephen Bowen and Pilot Warren Hoburg, along with mission specialists Roscosmos cosmonaut Andrey Fedyaev, and UAE (United Arab Emirates) astronaut Sultan Alneyadi. Liftoff will be powered by SpaceX’s Falcon 9 rocket.

The flight crew is seated inside their Dragon Endeavour spacecraft preparing for their 24.5-hour journey to the International Space Station on NASA’s SpaceX Crew-6 mission. About 45 minutes prior to liftoff, the SpaceX launch director will conduct a poll of NASA and SpaceX mission managers to determine if they are ready for launch.

With a successful “Go for launch” decision, the crew access arm will retract, the crew will close their visors, the launch escape system will be activated in the unlikely event of a contingency, and SpaceX will begin loading propellant into the Falcon 9 rocket for launch.

The Crew-6 flight will carry NASA astronauts Stephen Bowen, commander; Warren Hoburg, pilot; and mission specialists UAE (United Arab Emirates) astronaut Sultan Alneyadi and Roscosmos cosmonaut Andrey Fedyaev. Launch is targeted for 12:34 a.m. EST Thursday, March 2, from Kennedy Space Center’s Launch Complex 39A in Florida.

NASA astronauts Stephen Bowen and Warren Hoburg, along with UAE (United Arab Emirates) astronaut Sultan Alneyadi and Roscosmos cosmonaut Andrey Fedyaev, are on their way to Kennedy Space Center’s Pad 39A after departing the Florida spaceport’s Neil A. Armstrong Operations and Checkout Building. They are right on schedule.

Before leaving, the flight crew paused to recognize family, friends, and support team members who gathered to see them off. They then climbed into their customized black Tesla Model X vehicles for the approximate 20-minute ride to the pad.

The crew’s vehicle is traveling in a convoy, including support team members and security personnel. At the launch site, the SpaceX Falcon 9 rocket and Dragon spacecraft Endeavour are ready for the crew’s arrival.

It is about three hours, 15 minutes until liftoff.
