TOKYO -- The second attempt to launch Japan's H3 rocket failed minutes after liftoff on Tuesday, as its second-stage engine did not ignite and the nation's space agency ordered the space vehicle to self-destruct.
Engineers at the Japan Aerospace Exploration Agency (JAXA), developer of the rocket, said they were unsure of the cause of the failure but were looking at the possibility that an electronics problem was involved, either in the control system of the rocket or in the second-stage engine itself.
