If you watch the sky about an hour after the sun goes down, you may see some “moving stars” But they’re not real starsThey are man-made satellitesAnd the biggest of all is the International Space StationISS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 eyesThe ISS is the biggest man-made satellite because scientists want to live on itThey 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 spacePeople will stay an study there with many of the things they have at homeLaboratories, living rooms and power stations are being builtThe ISS is the most ambitious(雄心勃勃) and expensive space program everBillions 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 explanation“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 experimentsChina sent some rice up to the ISS to find out what space would do to it

The ISS is not finished yetMore than 100 parts need to be put onScientists hope it will be finished as soon as possibleAfter it’s finished, more than 90%of the world’s population will be able to see the Space StationSo keep looking up, and maybe you’ll see it get bigger
