CAPE CANAVERAL, Fla. -- In the Space Shuttle Main Engine Processing Facility at NASA's Kennedy Space Center in Florida, space shuttle main engine No. 1 is outfitted with a new turbopump. A suspect turbopump experienced an issue during torque testing and had to be removed and replaced for Discovery's STS-133 mission to the International Space Station. Next, all three main engines will be transported back to Orbiter Processing Facility-3 and reinstalled. The shuttle and its STS-133 crew are targeted to deliver the Express Logistics Carrier-4 filled with external payloads and experiments, as well as critical spare components to the station later this year.
