Progress towards Artemis 2! NASA and Northrop Grumman technicians in Promontory, Utah, have applied insulation to the final booster motor segment for Artemis 2, the second flight of our deep space rocket, the Space Launch System, and Orion spacecraft. The insulation, applied to the interior of each steel motor segment, protects the casing from the heat generated by the propellant during launch and flight. The twin, five-segment solid rocket motor boosters for SLS are the largest, most powerful solid propellant boosters ever built. SLS uses both liquid and solid propellant to provide the thrust needed to launch the vehicle and send it to space. 💪The boosters provide more than 75% of the total thrust at launch and into the first two minutes of flight. Five motor segments are stacked together to create a single, very large motor for each booster. The manufacture and checkout of all 10 motor segments for Artemis 1, the first test flight of SLS and Orion, were completed earlier this year...
