History

The ISAS originated as part of the Institute of Industrial Science of the
University of Tokyo , abbreviated as or UTokyo, is a public research university located in Bunkyō, Tokyo, Japan. Established in 1877, the university was the first Imperial University and is currently a Top Type university of the Top Global University Project by ...

(IGY). By 1960, the Κ-8 rocket had reached an altitude of 200 km. In 1964, the rocket group and the ''Institute of Aeronautics'', along with scientific ballooning team, were merged to form within the University of Tokyo. The rocket evolved into the L (''Lambda'') series, and, in 1970, L-4S-5 was launched as Japan's first artificial satellite Ohsumi. Although ''Lambda'' rockets were only sounding rockets, the next generation of M (''Mu'') rockets was intended to be satellite launch vehicles from the start. Beginning in 1971, ISAS launched a series of

In 1981, as a part of university system reform, and for the mission expansion, ISAS was spun out from University of Tokyo as an inter-university national research organization, ''Institute of Space and Astronautical Science''.

The English name ''Institute of Space and Astronautical Science'' is still used, although the Japanese name was changed to 宇宙科学研究本部 (literally, ''Space Science Research Division'', whereas the previous name's literal translation was ''Space Science Laboratory''). In 2010, the name was changed back to the previous . Under JAXA, ISAS continues to be responsible for space-based astronomy, and lunar and planetary exploration missions.
