NASA’s Space X Crew-6 crew members are now boarding the Dragon spacecraft, Endeavour. As the crewmates board, their seats are configured in the upright position; later, prior to closure of the spacecraft’s side hatch, the seats will be rotated into a reclined position for flight.

The four Crew-6 crewmates – Commander Stephen Bowen, Pilot Warren Hoburg, Mission Specialist UAE (United Arab Emirates) astronaut Sultan Alneyadi, and Mission Specialist Roscosmos cosmonaut Andrey Fedyaev – are set to launch from Kennedy Space Center’s Launch Complex 39A in Florida at 12:34 a.m. EST, Thursday, March 2. They will dock the Dragon spacecraft, named Endeavour, to the forward port on the International Space Station Harmony module about 24.5 hours after liftoff.

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.

NASA’s SpaceX Crew-6 science mission includes cutting edge research aimed at keeping astronauts and spacecraft safe during deep space exploration, and studies that could lead to improved medical treatments for humans back on Earth.

Experiments include studies of how particular materials burn in microgravity, tissue chip research on heart, brain, and cartilage functions, and an investigation that will collect microbial samples from the outside of the International Space Station. These are just some of the more than 200 science experiments and technology demonstrations that will take place during the mission.

Liftoff is now about four hours away (12:34 a.m. EST) from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The mission will fly NASA astronauts Stephen Bowen and Warren Hoburg, UAE (United Arab Emirates) astronaut Sultan Alneyadi, and Roscosmos cosmonaut Andrey Fedyaev to the International Space Station for up to six months.

Stay with us as the countdown continues; we’ll keep you updated on the key milestones throughout this important mission. Starting at 9 p.m. EST, there will be a live broadcast on NASA Television and the agency’s website.
