National Space Development Agency of Japan

The National Space Development Agency (宇宙開発事業団, Uchū Kaihatsu Jigyōdan) of Japan, or NASDA, was a Japanese national space agency established on October 1, 1969 under the National Space Development Agency Law only for peaceful purposes. Based on the Space Development Program enacted by the Minister of Education, Culture, Sports, Science and Technology (MEXT), NASDA was responsible for developing satellites and launch vehicles as well as launching and tracking them.

Hideo Shima, chief engineer of the original Shinkansen "bullet train" project, served as Chief of NASDA from 1969 to 1977.

On October 1, 2003, NASDA merged with the Institute of Space and Astronautical Science (ISAS) and the National Aerospace Laboratory of Japan (NAL) into one Independent Administrative Institution: the Japan Aerospace Exploration Agency (JAXA).

SL-J was partially funded by Japan through NASDA; this cooperative Japanese-American mission launched a NASDA astronaut into Earth orbit using the Space Shuttle in 1992.
