Japan's H3 rocket returned to flight on Friday with the debut of a new low-cost variant, a much-needed success for the country's flagship rocket program. The launch from the Tanegashima Space Center successfully placed six small satellites into orbit, according to the Japan Aerospace Exploration Agency (JAXA).
This mission follows two previous failures for the H3 model, including one in December where the second-stage engine malfunctioned. A third failure would have significantly impacted Japan's future space endeavors, including a planned Mars mission.
