CAPE CANAVERAL, Fla., June 24 (UPI) — Kennedy Space Center technicians Thursday removed space shuttle Discovery’s three main engines in order to remove and replace a malfunctioning turbopump.
Workers at NASA’s Orbiter Processing Facility-3 at the space center also tested the shuttle’s power reactant distribution system, which serves Discovery’s electricity-generating fuel cells.
And at NASA’s Johnson Space Center, STS-133 astronauts Tim Kopra and Alvin Drew rehearsed spacewalk procedures Thursday at the facility’s Neutral Buoyancy Lab.??
All that activity is focused on Discovery’s planned Sept. 15 launch on its final scheduled mission into space. However, space agency officials said that date might be moved to Oct. 29, with STS-134 moving to February 2011. NASA said the requested rescheduling is under consideration and an announcement is expected by July 1.
“During space shuttle Discovery’s final spaceflight, the STS-133 crew members will take important spares to the International Space Station along with the Express Logistics Carrier 4,” the space agency said in a statement.
