Mitsubishi Heavy Industries, the prime contractor for Japan’s H-2B rocket, said Friday that engineers concluded a fire on the launch pad during a countdown earlier this month was most likely sparked by static electricity and stimulated by oxygen. The H-2B rocket launch has been rescheduled for Tuesday to start a resupply mission to the International Space Station.
