The gist
- Engineers found 9 spots of lost charred material on Orion's shield, compared with 103 after Artemis I.
- Outside Orion topped 4,000°F while the cabin stayed in the mid-70s°F.
- The result supports NASA's changed return path; it doesn't mean the shield came back untouched.
What happened
NASA says Orion's heat shield performed as expected as Artemis II brought 4 astronauts home safely. The agency had changed the return path, shortening the distance Orion could travel between entering the atmosphere and reaching the ocean.
Why it matters
The findings support the protection needed to bring astronauts safely home from lunar missions.
How we know
NASA's single-source mission assessment draws on engineering data, inspections, counts of material-loss spots and internal x-ray scans of the returned shield.
What we don’t know yet
The result does not mean the shield emerged untouched. Researchers are continuing material tests and thermal analysis, and that work will inform future heat shields.

NASA lunar battery prototypes survive extreme cold in tests
NASA reports that prototype solid-state batteries operated at minus 112 degrees Fahrenheit with slightly reduced performance and survived colder exposure without damage.
