For those who follow NASA’s human spaceflight program, a burning question for the last year-and-a-half has been what caused the Orion spacecraft’s heat shield to crack and chip away during atmospheric reentry on the unpiloted Artemis I test flight in late 2022.
Multiple NASA officials said Monday they now know the answer, but they’re not telling. Instead, agency officials want to wait until more reviews are done to determine what this means for Artemis II, the Orion spacecraft’s first crew mission around the Moon, officially scheduled for launch in September 2025.
“We have gotten to a root cause,” said Lakiesha Hawkins, assistant deputy associate administrator for NASA’s Moon to Mars program office, in response to a question from Ars on Monday at the Wernher von Braun Space Exploration Symposium.
