Northrop Grumman has supplied rocket propulsion for NASA’s Apollo and Space Shuttle Programs and developed the five-segment SLS solid rocket booster based on the flight-proven design of the space shuttle boosters. Artemis IV segments are currently being cast with propellant and the first BOLE booster composite segment case to be used for development testing completed winding in October. “This opportunity for early learning on next-generation systems will help us develop an enhanced booster that is ready to support the greater payload demands of the SLS rocket through 2031.”īooster segments for Artemis II, the first crewed Artemis mission, and Artemis III, the mission that will land the first woman and first person of color on the lunar surface, are complete. “Continuous product improvements and obsolescence mitigation helps NASA achieve its long-term mission to utilize SLS for its Artemis program,” said Wendy Williams, vice president, propulsion systems, Northrop Grumman. The award also included follow-on production and flight sets for Artemis IV through Artemis VIII, and a BOLE booster set for Artemis IX. Northrop Grumman was awarded a contract to develop the BOLE booster in December 2021. Today’s test evaluates new materials and demonstrates a new motor ignition system and an electronic thrust vector control system that steers the motors to provide data for the development of the next-generation Booster Obsolescence and Life Extension (BOLE) boosters. Over 300 measurement channels assessed the 154-foot-long solid rocket booster as it fired for just over two minutes producing upwards of 3.6 million pounds of thrust. The five-segment solid rocket booster for NASA’s SLS rocket tested for early learning in support of next-generation systems at Northrop Grumman’s Promontory, Utah, test area.
