Victor Glover Shows Off Immune Biomarkers Sample Bag

art002e027801 (April 8, 2026) – NASA astronaut Victor Glover shows off the sample bag for the Immune Biomarkers study aboard the Orion spacecraft. During the Artemis II mission, the crew collected saliva samples for this study. Samples will be analyzed for proteins, enzymes, and other biomarkers that monitor immunity, inflammation, nutritional status, bone health, and radiation effects, to determine how crewmembers adapted to deep spaceflight conditions.
