Rapporterad av AI

Tokyo-based startup Space One has postponed the launch of its Kairos small rocket's No. 3 unit until March, citing a detailed weather analysis. The rocket is set to carry five satellites, with the launch window running until March 25.

Space One, a Tokyo-based startup, has delayed the launch of the No. 3 unit of its Kairos small rocket, originally set for Wednesday. The rocket was scheduled to lift off between 11 a.m. and 11:20 a.m. from the company's Spaceport Kii site in Kushimoto, Wakayama Prefecture.

The firm stated that a new launch date will be announced two days in advance or earlier. Previous attempts with Kairos No. 1 and No. 2 units ended unsuccessfully in March 2024 and December of the same year, respectively.

Space One aims to achieve Japan's first satellite orbit insertion using a rocket developed entirely by the private sector.
