The heat shield was one of the most talked-about parts of the Orion spacecraft, with some wondering whether it was up to the job after the heat shield onboard the uncrewed Artemis I mission showed signs of charring.

“Diver imagery of the spacecraft’s heat shield initially taken after splashdown and further inspections on the recovery ship found the char loss behavior observed on Artemis I was significantly reduced, both in terms of quantity and size,” NASA says.
Futurism notes that after the Artemis I heat shield showed signs of damage, experts like retired NASA astronaut Charles Camarda expressed reservations that the heat shield might not be up to task. The trajectory of Artemis II’s reentry was adjusted to minimize the heat build-up.
People noticed the white mark on the underside of Orion (enlarged), but NASA Administrator Jared Isaacman assuaged fears. | Photo by NASA/Josh Valcarcel.One photo showing the Orion spacecraft parachuting down into the Pacific Ocean raised eyebrows after it appeared to show a chunk of material missing from underneath where the heat shield is located. But as Gizmodo reports, NASA administrator Jared Isaacman said it was an expected ablation.
“The discoloration was not liberated material,” he said on April 12. “The white color observed corresponds to the compression pad area and is consistent with the local geometry, AVOCAT byproducts, and transitional heating environments. We observed this behavior in arc jet testing and expected it in this compression pad area.”
While initial assessments about the heat shield’s performance are good, the space agency will inspect it more closely in the coming months.
This past weekend, PetaPixel staff picked their favorite photos from Artemis II.
