     If you watch the sky about an hour after the sun goes down, you may see some "movingstars". But
they're not real stars. They are man-made satellites. And the biggest of all is the International Space
Station ( ISS国际空间站).
     From now until July is the best season 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 on it. They
think that the best way to learn more about space is to live there.
     When the space station is finished, it will be like a city in space. People will stay and study there with
many of the things they have at home. Laboratories, living rooms and power stations are being built. The
ISS is the most ambitious(雄心勃勃) and expensive space program ever.
     Billions of dollars are being spent on it every year.
     Scientists hope that the ISS will be a stepping-stone (垫脚石) for future space exploration.
     "The ISS will help us better understand the human body, explore space and study the earth. It can
help us make life on the earth better," said Kathryn Clark, an ISS scientist.
     China is not an ISS country, but it has helped with some of the experiments. China sent some rice up
to the ISS to find out what space would do to it.
     The ISS is not finished yet. More than 100 parts need to be put on. Scientists hope it will be finished
as soon as possible. After it's finished, more than 90% of the world's population will be able to see the
Space Station. So keep looking up, and maybe you'll see it get bigger.
