Space One KAIROS 3rd Flight - 2026-03-05 02:10 UTC

Space One launched its Kairos rocket on its third flight attempt on March 5, 2026, at 11:10 JST, or 02:10 UTC. The vehicle lifted off within the scheduled window of 11:10 to 11:20 JST. During first stage flight the rocket's autonomous flight termination system determined that mission success was difficult and activated flight termination measures. This resulted in an aerial explosion. All payloads fell into the Pacific Ocean. The outcome repeated the failure from the first flight. Space One maintained the live video stream throughout the event and showed a replay of the failed launch afterward. The company issued a preliminary cause statement shortly after the stream ended. The statement clarified that the Kairos 3 rocket itself made the autonomous decision to terminate without ground command. Forum participants noted the company's transparency in keeping the feed active and sharing details promptly. They expressed regret over the loss of the mission and the payloads. The satellites listed in pre-launch TLE data included NUTSAT-3, AETS-1, SC-Sat1a, TATARA-1R, and HErO.
