Space One's Kairos No. 2 rocket lifted off from a site in the mountainous prefecture of Wakayama in central Japan.
The company said it had aborted the flight after concluding that it was unlikely to complete its mission. The cause of the flight failure was not immediately known. Space One is expected to give further details at a news conference later Wednesday.
Space One aims to be Japan’s first company to put a satellite into orbit, hoping to boost to Japan’s lagging space industry with a small rocket for an affordable space transport business.
Wednesday's flight, postponed twice from Saturday due to strong winds, came nine months after a failed debut flight in March, when the rocket was intentionally exploded five seconds after takeoff. The flight was carrying a government satellite that was intended to monitor North Korea’s missile launches and other military activities.
Kairos No. 2 rocket was carrying five small satellites, including one from the Taiwanese space agency and several from Japanese startups.
Space One said it had fixed the cause of the debut flight failure, which stemmed from a miscalculation of the rocket’s first-stage propulsion.
