Financials: Space-derived revenue at Mitsubishi Heavy Industries slipped to $368 million last year, or only 1.5 percent of the manufacturing giant's overall income, hurt by a general downturn in the Japanese launch industry climate.

Space Business: Part of the Mitsubishi keiretsu or corporate network (as is Mitsubishi Electric Corp.), Mitsubishi Heavy Industries is the leading manufacturer of Japanese rockets and rocket engines.

As the primary Japanese contractor to the International Space Station, the company will be responsible for building KIBO (the Japanese Experiment Module) and the automated HTV supply transfer vehicle. Once scheduled to join the ISS in 2002-3, the planned launch of these components have been pushed back to 2004.
