Artemis II reentry and splashdown: Everything the astronauts will experience

Orion will slam into Earth's atmosphere at more than 30 times the speed of sound, in what NASA expects to be the most demanding part of the Artemis II moon mission. On landing day, Artemis II entry flight director Rick Henfling and his team in mission control will run the final leg home of the 10-day spaceflight. After wake‑up, controllers will brief the four astronauts — Commander Reid Wiseman, pilot Victor Glover, Christina Koch, and Jeremy Hansen — on weather at the splashdown zone, then clear them to secure loose gear and climb into their pressure suits. A small final steering burn in space will aim the Orion spacecraft at a targeted patch of the Pacific Ocean, west of San Diego, California, where a Navy ship will be waiting Friday evening. On the ground, engineers will also arm backup flight software so the capsule can still guide itself through the atmosphere if its main computers fail. This home stretch carries extra tension following Artemis I, when pieces of Orion's heat shield unexpectedly broke off during the uncrewed test flight’s descent. Engineers later attributed the problem to hot gas building up faster than it could escape during that mission's so-called "skip" ent
