2024年12月5日 · Experts discussed results of NASA’s investigation into its Orion spacecraft heat shield after it experienced an unexpected loss of charred material during re-entry of the Artemis I uncrewed test flight. For the Artemis II crewed test flight, engineers will continue to prepare Orion with the heat shield already attached to the capsule.

2024年12月5日 · After extensive analysis and testing, NASA has identified the technical cause of unexpected char loss across the Artemis I Orion spacecraft’s heat shield. Engineers determined as Orion was returning from its uncrewed mission around the Moon, gases generated inside the heat shield’s ablative outer material called Avcoat were not able to vent ...

2024年10月29日 · NASA has determined why the Orion heat shield lost more material than expected on Artemis 1 but won’t disclose details until after it completes more tests.

2022年12月8日 · Orion’s heat shield will experience temperatures of around 5,000 degrees Fahrenheit – about half as hot at the Sun – during its return. After traveling beyond the Moon, nearly 270,000 miles from Earth, the capsule will work up a speed of 25,000 miles per hour.
