Four Humans Orbited The Moon So Doctors Could Poke Their Wrists With A Watch

Artemis II splashed down in the Pacific on April 10. Within a day, Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen were running an obstacle course so NASA could see what a wristwatch did up there.

Artemis II splashed down April 10. Within 24 hours, Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen were doing a mini obstacle course in spacesuits offloaded to one-sixth gravity, which I'm told is research.

The ARCHeR study collected wrist-worn device data and simulated manual docking. Immune Biomarkers swabbed their saliva for dormant viruses. The organ chips containing their bone marrow flew around the Moon and went to a Boston lab called Emulate for single-cell RNA sequencing. Genuinely cool. Then I remembered the chips got a better trip than I'll get this decade.

Initial data wrapped 45 days after splashdown. NASA will publish 11,500 image files and over 100 audio recordings. Four people saw the Moon for seven hours and came home to fill out forms.
