Northrop Grumman Innovation Systems continues production of solid rocket booster (SRB) segments for the first launches of NASA’s Space Launch System (SLS) rocket at their Promontory Propulsion Systems facility in Northern Utah. Mixing of solid propellant for the SLS boosters and casting it in each of the ten segments for the second flight set is nearing completion as technicians put the final touches on the set for the first launch.
The first set of segments will wait in storage in Utah until next year; in the meantime, NGIS will continue production of the remaining deliverables in the current contract, including the third flight set and a ground test booster. After propellant casting, the segments go through inspections and final assembly before work is complete.
Once NASA is ready to start assembling the first SLS vehicle in Florida, the first flight segments will take a group train ride to the launch site.
EM-1 segments done, stored at Promontory until next year:
Northrop Grumman Innovation Systems (formerly Orbital ATK) produces the five-segment solid rocket motors (RSRMV) that form SLS boosters at their Promontory facility north of Salt Lake City. Cases for a booster are assembled into five segments, lined with insulation, loaded ...
