Startup · United States
Axiom flew a Red Hat-based prototype to the ISS in August 2025 and two compute nodes on Kepler's relay satellites in January 2026, and plans a petabyte-class ISS node with Spacebilt in 2027. The hardware is edge class, and Axiom has published no workload results.
Shared launches: Ax-1 (2022-04-08) with AWS; CRS-33 (2025-08-24) with IBM / Red Hat; Kepler Tranche 1 (2026-01-11) with Kepler.
Stage 4 of 7: Payload demo flown
Its first two ODC nodes launched as hosted payloads on Kepler satellites on 11 Jan 2026, after the AxDCU-1 prototype reached the ISS in August 2025.[1]
What the stage means: Compute or storage flown as a hosted payload or on the ISS.
