Engineers at NASA's SSC successfully completed the first test of the redesigned Space Shuttle Main Engine (SSME). NASA planned to use the redesigned SSME in the first Shuttle mission after the Columbia tragedy ~ the mission that NASA often called the Return to Flight Mission. The test of the SSME lasted for 520 seconds, the amount of time a Space Shuttle requires to reach orbit. Each Space Shuttle has three SSMEs ~ reusable rocket engines capable of generating 400,000 pounds (181,000 kilograms) of thrust.
