一、概况 M-3S-1火箭是M-3S系列的第一枚火箭。1980年2月17日,东京大学宇宙航空研究所在鹿儿岛县肝属郡内之浦街的鹿儿岛宇宙空间观测所成功地发射了M-3S-1火箭,并将代号为“MS-T4”的工程试验卫星运载入轨。火箭发射后,飞行正常。9分31秒钟后,MS-T4卫星被送入了近地点519.6公里、远地点608公里的地球轨道,轨道倾角为38.7°,运行周期为1小时36分。MS-T4卫星被东京大学宇宙航空研究所命 I. Overview M-3S-1 rocket is the M-3S series of the first rocket. On February 17, 1980, the Institute of Astronautics and Astronautics at the University of Tokyo successfully launched the M-3S-1 rocket at the Kagoshima Space Observatory in Pu-Pu, Goupag-gun, Kagoshima Prefecture and assigned the code “MS-T4” Engineering test satellites carry into orbit. After the rocket was launched, the flight was normal. After 9 minutes and 31 seconds, the MS-T4 satellite was sent to Earth’s orbit at a distance of 519.6 kilometers and a distance of 608 kilometers, with an orbit inclination of 38.7 ° and an operating period of 1 hour and 36 minutes. The MS-T4 satellite was ordered by the Tokyo Institute of Aeronautics and Astronautics
