Shuttle Discovery is inside its processing hangar at NASA’s Kennedy Space Center in Florida, undergoing standard launch processing for the STS-133 mission to the International Space Station. Technicians today will begin removing hydrogen tank No. 5 from Discovery’s power reactant storage and distribution, or PRSD, system. The system’s oxygen tank No. 5 is planned for removal this weekend. Part of the shuttle’s electrical power system, the PRSD stores hydrogen and oxygen at supercool temperatures for the fuel cells.
At NASA’s Johnson Space Center in Houston, the STS-133 astronauts are meeting today with the STS-132 crew for a mission debrief, and practicing entry skills in the motion-based simulator.
