The Booster Obsolescence and Life Extension (BOLE) booster is the next generation five-segment solid rocket booster that will support NASA’s Space Launch System (SLS) rocket on Artemis missions to the moon and beyond.

The BOLE booster's composite case will replace the refurbished Shuttle Program-era steel case design expended on the first eight SLS flights and integrate upgraded structures, propellant materials and an electric thrust vector control system. This is the first demonstration motor (DM-1) static test of the BOLE booster required for certification.
