Japan's Space One to launch Kairos No. 3 rocket on Sunday

The Tokyo-based space development startup canceled the initially scheduled rocket launch on Wednesday, citing a forecast for unfavorable weather conditions.

According to Space One, the Kairos No. 3 unit is set to lift off from the company's Spaceport Kii launch site in the town of Kushimoto, Wakayama Prefecture, western Japan, between around 11:00 am and 11:20 am on Sunday.

The rocket will carry five satellites, including one developed by the Taiwan Space Agency.

This is the company's third rocket launch attempt, following the failures of the Kairos No. 1 unit in March 2024 and the No. 2 unit in December that year.

If the planned launch succeeds, it will mark the first successful launch of a rocket developed entirely by a private company in Japan.
