Engineers at NASA’s KSC completed the installation of a new main engine for Space Shuttle Atlantis. Modifications of previous engine designs included a new high-pressure fuel turbopump, strengthened and made more durable by a casting process, rather than by welding. During the roughly 8½ minutes that the engines operate during a Shuttle launch, they must perform at temperatures reaching 6,000°F (3,300°C). The improvements continued NASA’s practice of regularly updating the Shuttle’s components. (NASA, “New Main Engine Promises Even Safer Shuttle Ride,” news release 01-79, 26 April 2001.)
