欧空局今后十年空间探测战略

ESA'S SPACE EXPLORATIONAL STRATEY OF NEXT DECADE

欧空局目前正在研究今后十年的空间探测任务,这些任务可以分为两大类,一类是具有研究性的地球探测任务,另一类是可供使用的地球观察任务。这些研究要求的卫星质量不同,小的不足1000kg,大的可达3000kg;功率不同,小的不到500W,大的超过1500W;轨道高度也不同,从500km到800km。除降雨量观测任务由于飞行器结构和系统的限制是在低倾角轨道上执行外,其他大部分任务将在太阳同步轨道上执行。

ESA is studying with model missions identified for the next decade at present. These mission are expected to belong to two class, Earth Explorers of research nature, and Earth Watch of operational character. The studies lead to a rang of satellites, from less than 1000 kg to 3000 kg and power requirements from below 500 W to more than the 1500 W, orbit altitudes range from 500 km to 800 km. Though most mission are in sunsynchronous orbits, precipitation explorational mission is in low inclination orbit with implications on the spacecraft configuration and systems.
