Technicians completed installation of the German Aerospace Center TACHELES CubeSat within the Orion stage adapter inside the Multi-Payload Processing Facility at NASA’s Kennedy Space Center in Florida on Wednesday, Sept. 17, 2025. The TACHELES CubeSat, about the size of a shoebox, is one of the 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, TACHELES will collect measurements on the effects of the space environment on electrical components to inform technologies for lunar vehicles.
