Space junk is also thought as a great danger to spacemen .It’s reported that there are 9,000 man—made things flying in space.About 30﹪of these are satellites ,10﹪are spaceships ,and the rest are space junk .An explosion（爆炸）in 1996 made a cloud of 300,000 fragments,each at least 4mm in size ,and even a small piece of these knocked against a spaceship window and did some damage .Scientists are watching and reporting any possible danger all the time They are working on helpful ways to do with space junk .
