Orion Hot Fire Test Blazing a Safe Trail for NASA Missions to the Moon

The Northrop Grumman built attitude control motor (ACM) on Orion’s launch abort system was successfully tested on August 22, at their facility in Elkton, Maryland.

The 30-second trial by fire was the second to last test before it’s qualified for human spaceflight on Artemis 2 — the first mission with astronauts. During the static test, the ACM produced more than 7,000 pounds of thrust from eight valves, providing enough force to steer Orion and its crew to a safe distance.

The launch abort system is designed to transport Orion and its crew to safety in the event of an emergency during launch or ascent. It consists of three solid rocket motors: the abort motor pulls the crew module away from the launch vehicle; the ACM steers and orients the capsule; then the jettison motor ignites to separate the launch abort system from Orion for parachute deployment and a safe crew landing.

All three motors will be certified for future crewed flights after qualification tests are completed later this year. The launch abort system was stress tested earlier this year during the successful Ascent Abort-2 test.

These achievements brings Orion closer to safe flights with astronauts, paving the way for the first woman and the next man to land on the Moon by 2024.
