14.D    Junk is everywhere,even in space.Space junk travels at eight kilometers a second,according to an article in the Guardian.Catching it may be a little difficult.
    Luckily,scientists at the Swiss Space Center have a new cleaning plan.They are about to send a"cleaner satellite"into space.It will clean up space junk.Named uClean Space One'',the Swiss satellite finds its tareet and moves close to it When it reaches its target,it will catch the junk with a gripping claw(抓手).This is not going to be an easy task because both the satellite and the junk are traveling so fast.
    Once Clean Space One has caught the junk,all it has to do to get rid of it is to fly back to the Earth.This is because the junk will bum up when traveling through the atmosphere (大气层).The satellite itself,too,will bum up at the same time.
    So far,NASA has found 16,000pieces of junk that are larger than 10cm in diameter and more than 500,000pieces measuring between 1cm and 10cm.You can imagine how many even smaller ones there are in space.
    Space junk is dangerous for spacecraft and the International Space Station.Even a very small piece of junk could seriously destroy a satellite or spacecraft if they collide (碰撞).The International Space Station has to regularly change its orbit(轨道) to avoid space junk.
