If you watch the sky about an hour after the sun goes down, you may see some "moving stars". But they
aren't real stars. They're satellites, a machine that has been sent into space and goes around the Earth, moon,
etc. And the biggest of all is the International Space Station (ISS).
The ISS is the biggest satellite because scientists want to live on it. They think that the best way to learn
more about space is to live there. The space shuttle Discovery has taken off from the Kennedy Space Center
in Cape Canaveral, Florida several times and carried a few groups of astronauts to the International Space
Station.
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 expensive space program ever. Millions and millions of dollars are being spent on it every year.
Scientists hope that the ISS will be a stepping stone for future space exploration. "The ISS will help us
better understand the human body, explore (know more about) space and study the earth. It can help us make
life on the earth better," said Kathryn Clark, an ISS scientist.
Sixteen countries are in the program: The US, Russia, Canada, Japan, Brazil and 11 European countries.
China is not an ISS country, but it has helped with some of the experiments. In 2003, China sent some rice
up to the ISS to find out what space would do to it.
Twenty Chinese students talked directly to an astronaut (spaceman) in the International Space Station (ISS)
on radio in Nanjing, capital of east China's Jiangsu Province on Sunday, 2007. The 20 students, aged 10 to 19
from Shanghai, Guangzhou and Nanjing, began talking to Clayton C. Anderson, a 48-year-old American
astronaut at 18:50 p.m. at Nanjing No. 3 Middle School when the ISS was passing over Nanjing.
After it's finished, more than 90 percnt 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 and brighter.
