If you watch the sky about an hour after the sun goes down, you may see some "moving stars". But
they're not real stars. They are man-made satellites. And the biggest of all is the International Space Station
(ISS 國際空間站).
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 (墊腳石) 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.
