If you watch the sky for about an hour after the sun goes down,you may see some " moving stars". But they're not real stars. They're man-made satellites. And the biggest of all is the International Space Station.

   From May to July is the best time to watch the ISS flying over the earth. And people can see it just with their eyes.

   The ISS is the biggest man-made satellite because scientists want to live in it. They think that the best way to learn more about the space is to live there.

   When the space station is finished,it'll be like a city in space. People will stay and study there with many things they have at home. Labs , living rooms and power stations are being built. Billions of dollars are being spent on it every year.

   Scientists hope that the ISS will be a stepping-stone (跳板)for future space station.

"The ISS will help us better understand the human,explore space and study the earth. It can help us make life on earth better , " said Kathryn Clark , an ISS scientist.

   Sixteen countries are parts of the program : theU. S. A.,Russia,Canada,Japan, Brazil and other 11 European countries.

   China isn't a member of ISS,but it has made contributions to the experiments. In 2003 , China sent some rice to the ISS.
