这次升级的目的是想在现有功能的基础上添加接收和处理精密距离以及微波着陆系统近地数据的能力。
The upgrade is intended to add to the present features the capability to accept and process precision distance together with the MLS approach data.
照片的清晰度足矣让我们区分出其上是岩石还是人造物，距离最近的一张照片是阿波罗17号的着陆点（如图），这也是迄今为止距此着陆点最近的一张照片。
They offer a sharper look that more clearly distinguishes man-made objects from rocks. The closest images are of the Apollo 17 site from 1972.
他说这项任务不会在火星着陆，而是在距离火星100英里处飞行，然后使用其重力返回地球。
He said the mission wouldn't land but rather fly within 100miles of Mars and then use its gravitational pull to return to earth. Mr.
为了寻找到固态水，着陆器的发送点定位火星北部区域，但是过去还不知道将会在距离地面多深处找到。
The lander was sent to a spot on Mars' northern regions in hopes of finding frozen water, but just how deep underground it would be found was unknown.
无线电高度表测量的是飞机离地面而不是离海平面的距离，用于自动导航及仪表着陆系统上。
Radio altimeters measure the distance of an aircraft above the ground rather than above sea level, they are used in automatic navigation and Blind-landing systems.
他蜷起双足在沙滩上滑翔着陆，然后步测着沙滩上滑翔的距离，他的父母见了，着实为他担忧。
When he began sliding in to feet-up landings on the beach, then pacing the length of his slide in the sand, his parents were very much dismayed indeed.
