1.Scientists have found out that the radiation(辐射)is the greatest danger to spacemen in space.When spacemen are working in space,they are in danger of the radiation from the sun and other stars,which is bad for their health.The harm of the radiation won't be found until their children even grandchildren are born.Some special medicine may work a little,but no really effective medicine has been found so far.
Space rubbish is also thought to be a great danger to spacemen.It's reported that there were 9,000man-made things flying in space.About 30% of these are satellites,10% are spaceships,and the rest are space rubbish.An explosion(爆炸)in space in 1999made a cloud of 300,000 fragments,each at least 4mm in size.A small piece of these even knocked a spaceship window and caused some damage(损坏).
Scientists are watching and reporting any possible danger all the time.They are working to deal with space rubbish.Although space is really dangerous,it interests many people on the earth.In the near future,it may become possible for people to spend a few days in a space hotel.We may even choose to leave the earth and live in space in a few years.So we should do something to help improve the space environment.
