Teams from NASA and Northrop Grumman fire a ground-based version of a booster for the agency’s SLS (Space Launch System) rocket June 26. Secured horizontally in a test stand at Northrop Grumman’s test facility in Promontory, Utah, the single five-segment booster motor fired for more than two minutes and produced 3.9 million pounds of thrust. The booster for this test, known as Demonstration Motor-1 (DM-1), is the result of the Booster Obsolescence Life Extension (BOLE) project. This test was the first full-scale ground test of a new five-segment solid rocket motor. During the test, there was an abnormal event approximately 15 seconds before the end of the motor firing. Despite this event, NASA achieved several of the test’s primary objectives and received valuable data on technical risks identified ahead of the test. Testing this evolved booster for the SLS will help evaluate improvements and new materials in the boosters. The BOLE effort was launched to transition to a more efficient, lower cost commercial solution for the boosters for the SLS rocket. Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.
