NASA’s Artemis II mission finished after a ten‑day lunar fly‑by, and analysts are already dissecting every system that kept four astronauts safe.

Initial reviews show Orion’s heat shield behaved as expected, showing minimal char loss compared to the uncrewed Artemis I. Splashdown landed 2.9 miles from target, and the SLS core stage hit over 18,000 mph at engine cutoff.

A minor hiccup emerged when crew members flagged a urine‑vent line fault; mission specialist Christina Koch resolved the issue with ground help, prompting a review to avoid repeat problems. These findings inform 2027‑2028 crewed landings.
