Space shuttle Discovery will have its three main engines removed after a low-pressure oxidizer turbopump on engine 1 had an issue during a torque check. All three engines have to be removed to allow access to remove the center engine. The pump will be sent to Canoga Park, Calif., for repair. Engineers will consider several alternatives, including whether to wait for the engine and its new turbopump or to install another engine in Discovery that was slated for use on Endeavour. The engine work is not a hindrance to processing and is not expected to prompt a delay for the launch of the STS-133 mission.
The crew of Discovery is reviewing photo and television procedures today as they continue training for mission. The astronauts are also undergoing refresher training on International Space Station systems.
