NASA’s SpaceX Crew-3 astronauts participate in a countdown dress rehearsal at the agency’s Kennedy Space Center in Florida on Oct. 28, 2021, to prepare for the upcoming Crew-3 launch. Kayla Barron, mission specialist, runs through checkouts of her SpaceX spacesuit inside the crew suitup room in the Neil A. Armstrong Operations and Checkout Building. Barron, along with Raja Chari, commander, Tom Marshburn, pilot, and Matthias Maurer, with the European Space Agency, and also a mission specialist, will launch aboard the Crew Dragon atop the Falcon 9 to the International Space Station. Launch is targeted for no earlier than Nov. 6 at 11:36 p.m. EDT from Launch Complex 39A. Crew-3 is the third crew rotation flight to the space station for NASA’s Commercial Crew Program, and the first flight of a new Crew Dragon spacecraft.
