The Lockheed Martin and NASA Orion team has secured the 2,700 lb. Exploration Mission-1 (EM-1) Orion crew module into its structural assembly tool, also known as the “birdcage.” The crew module is the living quarters for astronauts and the backbone for many of Orion’s systems such as propulsion, avionics and parachutes.
“The structure shown here is 500 pounds lighter than its Exploration Flight Test-1 (EFT-1) counterpart,” said Mike Hawes, Lockheed Martin Orion vice president and program manager. “Once the final structural components such as longerons, bolts and brackets are added, total crew module structural weight savings from EFT-1 to EM-1 will total 700 pounds.”
From experience gained by building test articles, building and flying EFT-1, and now building the EM-1 crew module, the Lockheed Martin team is learning how to shed weight, reduce costs and simplify the manufacturing process – all in an effort to improve the production time and cost of future Orions.
“Our very talented team in Louisiana has manufactured a great product and now they have passed the baton to Florida,” said Hawes. “This is where we assemble, test and launch, and the fun really begins.”
At Kennedy Space Center, the crew module will undergo several tests to ensure the structure is perfectly sound before being integrated with other elements of the spacecraft. First it will undergo proof-pressure testing where the structural welds are stress tested to confirm it can withstand the environments it will experience in space. The team will then use phased array technology to inspect the welds to make sure there are no defects. Additional structural tests will follow including proof-pressure testing of the fluid system welds and subsequent x-ray inspections.
Once the crew module passes those tests it will undergo final assembly, integration and entire vehicle testing in order to prepare for EM-1, when Orion is launched atop NASA’s Space Launch System (SLS) for the first time. The test flight will send Orion into lunar distant retrograde orbit – a wide orbit around the moon that is farther from Earth than any human-rated spacecraft has ever traveled. The mission will last about three weeks and will certify the design and safety of Orion and SLS for future human-rated exploration missions.
