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. Matthias Maurer, with the European Space Agency (ESA), is inside the crew access arm leading to the company’s Crew Dragon spacecraft during the rehearsal. Maurer’s SpaceX spacesuit is embroidered with the ESA and SpaceX emblems. 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.
