Japan's new J-2 small satellite low-Earth orbit (LEO) launcher will be powered by two Russian liquid propellant engines and built by an industry team led by Ishikawajima-Harima Heavy Industry and Nissan, which was chosen over a Mitsubishi-led team.
The J-2 will replace the solid- propellant J-1, which will be grounded after its second flight in 2000. The launcher has been deemed too expensive for national interests and not viable in the commercial market.
The $28 million J-2 will make its first flight in March 2002 and will be able to place 3,000kg into LEO. The Russian engines have yet to be designated, but it is known that the second stage is likely to be powered by the first engine ever to use liquified natural gas.
Development of Japan's Hope-X prototype unmanned space shuttle demonstrator has been put on hold for a year to save costs.
