Japan aborts launch of 1st H3 rocket carrying defense sensor
Japan’s space agency has aborted the launch of the first of its new flagship series H3 rockets after booster engines failed to ignite. The rocket was carrying an observation satellite also fitted with an experimental infrared sensor that could detect missile launches. The Japan Aerospace Exploration Agency livestream and TV footage Friday showed white smoke billowing from its main engine. But a pair of auxiliary rockets didn't ignite, according to an announcement at the launch site. The agency is investigating the cause of the problem and no further details were immediately known. The H3 rocket was developed with $1.5 billion as a successor to the H-2A rocket.
