The KAIROS rocket (カイロスロケット), or Kii-based Advanced & Instant Rocket System, is a Japanese solid-fuel rocket designed to launch small satellites of mass up to 250 kg to low Earth orbit and up to 150 kg to sun-synchronous orbit by the private spaceflight company Space One.[1] It consists of 3 solid fuel powered stages and a liquid propellant upper stage.

Launches

Launch site

Launches are planned from Space Port Kii [ja; fr] in Kushimoto, Wakayama, Japan, a dedicated launch site built by Shimizu Corporation.[2] [3]

First launch

The first launch was planned on 9 March 2024[4] but was postponed because a ship was spotted in the "maritime warning area" set up in waters near the launch pad.[5][6][7] A new launch date has been set for March 13.[6] If successful, the company will become the first Japanese private-sector firm to place a satellite into orbit.[6][7]
