Japan's Space One Rocket Fails Third Consecutive Commercial Launch Attempt

Japan's private space company Space One experienced its third consecutive failure with the KAIROS No. 3 rocket, which self-destructed 69 seconds after liftoff on March 5, 2026, from Spaceport Kii. The solid-propellant rocket carried five experimental satellites but failed to reach orbit, impacting Japan's goal to establish a domestic commercial satellite launch industry and reduce reliance on foreign rockets amid growing space security concerns. Space One is investigating the cause, with no prior abnormalities detected before flight termination.
