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 American flag and Kayla Barron’s name embroidered on the SpaceX spacesuit she is wearing. 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.
