NASA Tests Largest SLS Rocket Booster at Utah Promontory

NASA and Northrop Grumman successfully tested the Booster Obsolescence and Life Extension (BOLE) solid rocket motor, the most powerful segmented solid rocket motor ever created, at Promontory Point, Utah. Designed for the Space Launch System (SLS) and Artemis missions, the BOLE booster aims to support lunar missions and potentially Mars exploration, generating nearly 4 million pounds of thrust. During the 140-second test, the motor burned over 1.4 million pounds of propellant and demonstrated advanced design features, although an explosive event involving the exhaust nozzle occurred about 100 seconds into the test; despite this, the booster continued firing and the test was deemed largely successful. The BOLE booster represents a new generation of propulsion hardware intended to replace aging shuttle-era boosters and extend the lifespan of the SLS rocket, which is critical for NASA's Artemis lunar program amid discussions about the program's future and funding. Additionally, educational initiatives like the Plant the Moon Challenge are engaging students worldwide in experiments simulating lunar and Martian agriculture, directly supporting NASA's Artemis goals and fostering STEM education in space exploration contexts.
