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.

Manufacture

IHI Aerospace [ja] manufactures the KAIROS rocket at Tomioka Plant in the city of Tomioka, Gunma Prefecture. ^[2]^[3] [[ファイル:CKT20111-C18-16_IHI_Aerospace_Tomioka_Plant.jpg|link=https://ja.wikipedia.org/wiki/%E3%83%95%E3%82%A1%E3%82%A4%E3%83%AB:CKT20111-C18-16_IHI_Aerospace_Tomioka_Plant.jpg%7Cthumb%7CIHI Aerospace Tomioka Plant (Geospatial Information Authority of Japan)]]

Launch site

Launches are planned from Space Port Kii [ja; fr] in Kushimoto, Wakayama, Japan, a dedicated launch site built by Shimizu Corporation.^[4] ^[5]

Launches

First launch

The first launch was planned on 9 March 2024^[6] but was postponed because a ship was spotted in the "maritime warning area" set up in waters near the launch pad.^[7]^[8]^[9] A new launch date has been set for March 13.^[8] If successful, the company will become the first Japanese private-sector firm to place a satellite into orbit.^[8]^[9]
