On this daily update of the Artemis II mission, we break down Flight Day 5 (Sunday, April 5, 2026).

This episode covers the high-stakes Orion Crew Survival System (OCSS) pressurisation tests, the crew's shift toward lunar geology and observation targets, and the exact orbital mechanics behind the late-night Outbound Trajectory Correction burn.
