NASA astronaut Victor Glover, and pilot for the agency’s SpaceX Crew-1 mission, participates in an egress training exercise on July 21, 2020, in Florida. The exercise involved simulating an emergency situation after splashdown of the Crew Dragon spacecraft. Mission specialist Shannon Walker and spacecraft commander Michael Hopkins – both NASA astronauts – also participated in the training, along with Soichi Noguchi, mission specialist and Japan Aerospace Exploration Agency (JAXA) astronaut. Glover, Walker, Hopkins, and Noguchi will launch to the International Space Station from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. Crew-1 will be the first operational mission to the orbiting laboratory under NASA’s Commercial Crew Program, following the agency’s certification of SpaceX’s crew transportation system.

Durrance practice Astronomy Laboratory 1 (ASTRO-1) experiment procedures in a space shuttle aft flight deck mockup in the Payload Crew Training Complex at the Marshall Space Flight Center (MSFC) in Huntsville, Alabama. For all Spacelab missions, shuttle crew members train regularly in the facility in preparation to operate experiments on their Spacelab missions. The ASTRO-1 crew will operate the ultraviolet telescopes and instrument pointing system (IPS) from Columbia's, Orbiter Vehicle (OV) 102's, aft flight deck. The seven-member ASTRO-1 crew will work around the clock, in 12-hour shifts, to allow the maximum number of observations to be made during their nine or ten days in orbit. In addition to the commander and pilot, the crew consistss of three MSs and two payload specialists. (MSs are career astronauts who are trained in a specialized field. Payload specialists are members of the science investigator teams who were nominated by their peers to operate their experiments on orbit. They are trained and certified for flight by NASA.)

KENNEDY SPACE CENTER, FLA. -- At NASA Kennedy Space Center's Launch Complex 39, astronaut rescue team leader Capt. George Hoggard, in the white sweatshirt, instructs members of the crew for space shuttle Endeavour's STS-123 mission on the operation of an M-113 armored personnel carrier. The crew members of space shuttle Endeavour's STS-123 mission will each practice driving the M-113 in turn as part of his training on emergency egress procedures. An M-113 will be available to transport the crew to safety in the event of a contingency on the pad before their launch. The STS-123 crew is at Kennedy for a full launch dress rehearsal, known as the terminal countdown demonstration test or TCDT. Endeavour's seven astronauts arrived at Kennedy's Shuttle Landing Facility in their T-38 training aircraft between 10:45 and 10:58 a.m. EST. The terminal countdown demonstration test provides astronauts and ground crews with an opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency training. Endeavour is targeted to launch March 11 at 2:28 a.m. EDT on a 16-day mission to the International Space Station. On the mission, Endeavour and its crew will deliver the first section of the Japan Aerospace Exploration Agency's Kibo laboratory and the Canadian Space Agency's two-armed robotic system, Dextre.
