Following the Artemis II crew’s April 10 splashdown, scientists continue analyzing mission data from astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen, including postflight health measurements and organ chip samples that orbited the Moon. Research covers immune biomarker analysis, motor control assessments in simulated lunar gravity, and deep space radiation exposure effects on human biology. NASA will release approximately 11,500 images and 100-plus audio recordings from lunar observations through the Planetary Data System archive for use by the broader scientific community.
