USSF-43 (ROOSTER-4 & Tetra-5)

The Rapid On-orbit Space Technology Evaluation Ring (ROOSTER)-4 will conduct on-orbit tests and demonstrations to enable technology maturation of the platform and prototype/experimental payloads.

Tetra-5, comprising of 2 satellites, will demonstrate key capabilities such as cooperative and prepared inspection, docking, on-orbit refueling, proximity operations, and next-generation autonomy techniques that will help to enable future on-orbit servicing capabilities, spacecraft autonomy, and sustained space maneuver. On this mission, the 2 spacecraft will be refueled by Astroscale's Provisioner spacecraft, launching on USSF-23.
