NASA’s Space Launch System (SLS) will conduct a test of Flight Support Booster-1 (FSB-1) Sept. 2, 2020 at Northrop Grumman’s test facility in Promontory, Utah. Northrop Grumman manufactures the two five-segment solid rocket boosters that will provide more than 75 percent of the vehicle’s thrust for the first two minutes of ascent. Live coverage of the test will begin at 2:45 p.m. EDT on NASA Television and the agency’s website.
FSB-1 is a full-scale, five-segment solid rocket booster ground test that supports flights of NASA’s Space Launch System. This is the same model booster that will power the SLS rocket and Orion capsule on the Artemis I mission. The test is scheduled for 1:05 MDT, 3:05 p.m. EDT and has a planned duration of a little over 2 minutes, the same amount of time that the boosters power the rocket during liftoff and flight. The objective of the test is to confirm motor performance and manufacturing quality for potential new materials and processes that will be used in boosters supporting future Artemis missions.
