Inside the Multi-Payload Processing Facility at NASA’s Kennedy Space Center in Florida, on Tuesday, Aug. 26, 2025, technicians with the Korea AeroSpace Administration (KASA) inspect the K-Rad Cube, one of several international CubeSats slated to fly on NASA’s Artemis II test flight in 2026. Deploying in high Earth orbit from a spacecraft adapter on NASA’s SLS (Space Launch System) rocket after Orion is safely flying on its own with its crew of four astronauts, K-Rad Cube will use a dosimeter made of material designed to mimic human tissue to measure space radiation and assess biological effects at various altitudes across the Van Allen radiation belts, a critical area of research for human presence at the Moon and Mars.
