Launching a space program
Abstract
Japan's NASDA has undertaken the development of the H-I and H-II advanced boosters for spacecraft lofting to GEO. The H-I will employ a first-stage strap-on booster, a cryogenic second stage, and a third-stage solid rocket motor; two- and three-staged configurations will be used for medium altitude missions and geosynchronous missions, respectively. The H-II's first stage will be a single high-pressure cryogenic engine, rated at 186,000 lbs; the two solid rocket boosters that will be used to augment its thrust will incorporate thrust vector control. The second stage will be very similar to that of the H-I, but upgraded to generate 24,000 rather than 21,000 lbs of thrust.
