About Space One
Space One is a Japanese commercial launch company developing the KAIROS solid-fuel small rocket for responsive satellite launches. Founded in 2018 by Canon Electronics, IHI Aerospace, Shimizu Corporation, and Japan Bank for International Cooperation, the company aims to become Japan's first private orbital launch provider. Space One conducted KAIROS's inaugural launch attempt on March 13, 2024, from its Kii Spaceport in Wakayama Prefecture — the first privately-operated orbital launch site in Japan — but the vehicle exploded shortly after ignition due to a flight termination system activation.
The company is analyzing the failure and preparing for a second launch attempt. KAIROS is designed to deliver 250 kg to SSO, targeting the responsive launch market for Japanese government and commercial satellite customers.
