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. In this view is a close-up of the NASA and SpaceX embroidered emblems on the SpaceX spacesuit worn by NASA astronaut Kayla Barron. Barron is inside the crew access arm leading to the company’s Crew Dragon spacecraft during the rehearsal. The four-person crew will launch aboard the Crew Dragon atop the Falcon 9 on Oct. 31 to the International Space Station. Launch is targeted for 2:21 a.m. EDT from Pad 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.
