low earth orbit

They're primarily designed for Low Earth Orbit ( LEO)-an easily accessible region of space from around 200 to 800 miles above Earth, where human-tended missions like the Hubble Space Telescope and the International Space Station ( ISS) hang out.

它们主要是为近地轨道而设计的——近地轨道是距离地球200至800英里的一个较为容易进入的空域，像哈勃太空望远镜和国际空间站这样需要人类维护的太空设施就在这里运行。
