Detailed History of ISAS Rockets
Thirty five years have passed since a rocket group of the
Institute of Industrial Science of University of Tokyo, the predecessor
to ISAS, carried out flight experiments of a series of tiny test rockets
called Pencil. The Pencil was 1.8cm in diameter, 23cm long and weighed
200g. Passing through the development of Baby, Kappa (K), Lambda (L) and
Mu (M), solid propellant rockets in Japan have now reached the latest
version, the M-V vehicle, which can carry payloads 140 times bigger (in
diameter and length) and 700,000 times heavier than the original Pencil. With consolidation into JAXA, the development of the M-V was stopped and JAXA is now developing a smaller satellite launcher, the Epsilon (E) rocket. However, its development is not under the control of ISAS activities. |
