H-II Transfer Vehicle
Japan (NASDA) began development of the HOPE-X experimental shuttle spaceplane in the 1980s, to be launched on its H-IIA expendable launch vehicle. A string of failures in 1998 led to funding reductions, and the project's cancellation in 2003 in favor of participation in the International Space Station program through the "Kibō" Japanese Experiment Module and H-II Transfer Vehicle cargo spacecraft. As an alternative to HOPE-X, NASDA in 2001 proposed the Fuji crew capsule for independent or ISS flights, but the project did not proceed to the contracting stage.
