Japan's largest rocket company, Mitsubishi Heavy Industries (MHI), has received a vote of confidence as it seeks to compete for commercial launches in an increasingly crowded market. Earlier this month, the company announced an agreement with satellite operator Inmarsat for a launch in 2022 or later.

Significantly, the flight will take place on Mitsubishi's new H3 rocket, which was designed and developed to fly at a lower cost in order to attract more commercial business. It was the first commercial contract for the rocket, which is set to debut in 2020 by launching a satellite payload for Japan's space agency, JAXA.

JAXA and MHI want to increase the country's number of orbital launches annually from the current average of four to about eight. The only realistic way to do this is to increase launch orders from commercial companies. And as MHI has sought to do this, it seems to have found a good partner in Inmarsat. Already, in September 2017, Inmarsat selected MHI's H-2A rocket for the launch of its Inmarsat-6 F1 satellite in 2020.
