Artemis II final tests
NASA’s Artemis II crew is in return‑to‑Earth checklist mode, testing manual piloting and compression garments as they head for a San Diego splashdown targeted around 8:07 p.m. ET Friday. On Flight Day 8 the Orion spacecraft was about 200,278 miles from Earth and 83,549 miles from the Moon while the crew ran those in‑flight checks ahead of reentry. Teams say weather looks generally mild for splashdown, though a Pacific storm is still being monitored. (nasa.gov) (gizmodo.com) (abcnews.com)
A Moon mission does not end when the spacecraft turns around. The hardest part is the last plunge, when a capsule hits Earth’s atmosphere fast enough to turn air into a furnace and then has to land in the Pacific Ocean close enough for recovery ships to reach it. (nasa.gov) That is why NASA spent Flight Day 8 on return drills instead of sightseeing. The Artemis II crew was already back on the homeward leg after looping around the far side of the Moon on April 6, and NASA said Orion is targeting a Pacific splashdown on April 10. (nasa.gov) Artemis II is not a landing mission. It is a 10-day crewed lunar flyby that launched on April 1, 2026, to prove that the Space Launch System rocket and the Orion spacecraft can keep four people alive and working beyond low Earth orbit. (nasa.gov) Orion is basically a deep-space lifeboat with a heat shield. NASA built it to carry astronauts to the Moon, keep air and water working for days, and then survive reentry so the same crew can be pulled from the ocean at the end. (nasa.gov) The path home is designed like a slingshot in reverse. NASA put Artemis II on a free-return trajectory, which means Earth’s and the Moon’s gravity do most of the steering and naturally bend Orion back toward Earth even if no one ever lands on the Moon. (nasa.gov) That built-in path does not remove the need to practice flying. NASA’s press kit says the mission includes manual piloting work because Artemis III crews will need to guide Orion during rendezvous and docking operations in lunar orbit, and you cannot fully rehearse that on the ground. (nasa.gov) By Flight Day 8, the crew was 200,278 miles from Earth and 83,549 miles from the Moon, which is far enough that every checklist item is being done in the real deep-space environment instead of a simulator. NASA said the astronauts used that day to test the garment worn under their survival suits and to prepare for reentry. (nasa.gov) That garment is meant to fight a very ordinary problem with a very space-specific cause. After days in microgravity, some astronauts get dizzy or faint when gravity returns, so NASA has the crew test an orthostatic intolerance garment that helps keep blood pressure and circulation up during the trip back down. (nasa.gov) NASA is also still learning what breaks on a real crewed trip beyond low Earth orbit. Gizmodo reported that Orion’s modified Universal Waste Management System toilet jammed a urine collection fan soon after launch and later had trouble venting stored urine, forcing the crew to use backup collection bags while engineers worked the problem. (gizmodo.com) Those glitches are exactly why Artemis II exists. NASA says the mission is supposed to prove Orion’s life-support systems in deep space before Artemis III tries the much harder job of sending astronauts into lunar orbit for docking and, eventually, a Moon landing. (nasa.gov) If the schedule holds, Orion will finish having traveled about 695,081 miles from launch to splashdown, with a closest pass of about 4,070 miles above the lunar surface and a maximum distance of 252,760 miles from Earth. Those are test-flight numbers, but they are also the reason every “small” check on the way home matters. (nasa.gov)
