Before Going to Sleep on Flight Day 5, the Artemis II Crew...
(April 6, 2026) - Before going to sleep on flight day 5, the Artemis II crew snapped one more photo of the Moon, as it drew close in the window of the Orion spacecraft. Orion and the four humans aboard entered the lunar sphere of influence at 12:37 a.m. EDT on April 6, at the tail end of the fifth day of their mission. That marked the point at which the Moon's gravity had a stronger pull on the spacecraft than the Earth's. Artemis II's closet approach to the Moon will come on flight day 6, as they swing around the far side before beginning their journey back to Earth. About an hour after entering the lunar sphere of influence, Artemis II Mission Specialist Christina Koch said, "We are now falling to the Moon rather than rising away from Earth. It is an amazing milestone!"
