Potential solutions to the heat shield issue for Artemis II include altering the spacecraft’s trajectory during reentry or making changes to the heat shield itself. The latter option would require partially disassembling the Orion spacecraft at NASA’s Kennedy Space Center, something that would probably delay the launch date from September 2025 until 2027 at the earliest. Another alternative could be to do nothing and fly the Artemis II mission as is.

“The entire trade space is open,” Koerner said. "But as far as the actual Artemis II mission, right now, we’re still holding to the September ’25 launch date, knowing that we have still a lot of work to do to close out the heat shield investigation.”

Oof, a 2-year slip in the Artemis schedule would be a bit of a setback, but those chunks missing out of the heat shield didn’t exactly inspire confidence. Hope they can figure out the root cause and apply a fix in a timely manner.
