据最近参加巴黎国际宇航联合会的日本代表透露,日本正在评价用国产H-1火箭发射一颗月球卫星的可能性。该卫星将为日本扩大深空间探测能力作出贡献。日本宇宙航空研究所和宇宙开发事业团共同负责这项任务。据说该月球卫星的基线重量为650公斤,将采用遥感技术,分如下三个阶段完成飞行任务: 第一阶段,卫星将进入100—150公里×3000—4000公里的月球极地轨道,飞行一个月左右,利用地球上的雷达跟踪测定月球重力的谐函数。第二阶段,卫星变轨到100公里的圆轨道上飞行10—12个月,以绘制月面的地形图。第三阶段,卫是的轨道高度降低到约50公里,用2—3个月时间详细观测特定的月面区域。星上仪器生要有,伽傌射线分光仪、荧
According to the Japanese representative recently participating in the Paris International Astronautical Federation, Japan is evaluating the possibility of launching a lunar satellite with a domestic H-1 rocket. The satellite will contribute to Japan’s efforts to expand deep space exploration. Japan Aeronautics and Space Administration and cosmic development group jointly responsible for this task. The lunar satellite is said to have a baseline weight of 650 kg and will use remote sensing technology to accomplish the mission in three phases: In the first phase, the satellite will enter the lunar polar orbit at 100-150 km x 3000-4000 km and fly about a month , Using the earth’s radar tracking to measure the lunar gravity’s harmonic function. In the second phase, the satellites orbit to 100 kilometers of circular orbits for 10-12 months to map the lunar topography. In the third phase, the height of the orbit is reduced to about 50 km and the specific lunar region is observed in detail for 2-3 months. Star instrument must have, gamma ray spectrometer, Ying
