Test of New SLS Booster Design Encounters Nozzle Anomaly

On June 26, 2025, Northrop Grumman conducted the first full-scale static test of the Booster Obsolescence and Life Extension (BOLE) solid rocket booster, a next-generation component intended for NASA’s Space Launch System (SLS) Block 2 configuration. The test, performed at the company’s Promontory, Utah, facility, aimed to validate the BOLE’s advanced design but was marred by an anomaly in the booster’s nozzle, raising questions about its development timeline and the SLS program’s future.
