Summary
| Description | Northrop Grumman conducted the first test firing of its Booster Obsolescence and Life Extension (BOLE) five-segment solid rocket motor at its Promontory production and test site in Utah. The Development Motor 1 (DM-1) fired Thursday, June 26, at 12:25 PM MDT (18:25 UTC) and lasted for close to two minutes and 20 seconds, burning over 1.4 million pounds of propellant. The BOLE motor is intended for use on the Block 2 version of NASA’s Space Launch System (SLS) rocket, beginning with the Artemis IX mission. Featuring unpainted composite casings with copper wiring wrapped around them for protection against lightning, the booster generated over 4 million pounds of thrust upon ignition and burned for approximately two minutes and 20 seconds. Sensors monitored hundreds of parameters using 763 channels of data, and a carbon dioxide quench system helped to safe the booster after its firing. The BOLE DM-1 motor turned out to be the second most powerful solid rocket motor ever tested, behind on |
