【推荐1】Most people have a place to call home on Earth. What about in outer space? The International Space Station(ISS) became our first “home” in space in 2000. It welcomed its first crew that year, paving the way for 20 years of future research.

“You just have this impression that we’re all citizens of not a particular country, but of the planet,” former NASA astronaut Scott Kelly told National Geographic about working in ISS. “We’re all in this thing called humanity together.”

Over the past 20 years, the ISS has mainly been used as a science lab, hosting 241 people from 19 countries, according to NASA. They have gone on spacewalks, done research on how space affects the human body, and even grown plants in space.

The station’s development has also benefited people on Earth. For example, the station’s water purification(净化) technology has been used in poor areas to provide clean drinking water. The station also helps to warn us of natural disasters, such as earthquakes.

However, after being our home in space for over 7000 days, the station is starting to get old. It has leaked(泄露) air a few times. Scientists think that the station can keep working until 2024. After that, scientists will bring it down to Earth. It is believed that Earth’s atmosphere will burn up most of the station. Other debris(残骸) will fall into the Pacific Ocean.

In the future, space will be home to more stations like the ISS. NASA is building a space station that is smaller than the ISS near the moon. Also, China will have its own space station up and running in 2022.
