Space One says it plans to launch the No. 3 unit of its Kairos small rocket between around 11 a.m. and 11:20 a.m. on Sunday

Space One said Friday that it would launch the No. 3 unit of its Kairos small rocket carrying artificial satellites on Sunday morning.

The Tokyo-based space development startup canceled the initially scheduled 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, between around 11 a.m. and 11:20 a.m. 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.
