Overview
- Lifting off from Spaceport Kii, the solid-fuel Kairos appeared to fly normally before an energetic event about 70 seconds into ascent produced visible fragments.
- Space One said it activated the rocket’s flight-termination system after determining mission success was unlikely and declared the mission over within minutes.
- The flight was carrying five small satellites from Japanese organizations and Taiwan’s space agency, which were not delivered to orbit, and no injuries were reported.
- The attempt followed multiple postponements, including weather delays and a scrub when a safety system activated shortly before a prior countdown.
- This marks Kairos’s third consecutive failure after a 2024 first-stage motor issue and a later thrust-vector-control problem, raising stakes for Space One, backed by Canon and IHI Aerospace and holding a Japan Defense Ministry launch contract.
