Wherever people live or work, there's rubbish and people have to clean it up or take it away. Rubbish men come and collect your garbage(垃圾) from the bins outside your home every day. This week a team of highly trained rubbish men are going into space.
Among the team of three is Leroy Chiao, a Chinese American astronaut(宇航員). He and two Russians will rocket into space for the long-distance garbage collection at the International Space Station(ISS). The mission also includes making repairs to the generators(發(fā)生器) on the space station that recycle waste to produce oxygen and water.
They will bring back to earth waste that cannot be recycled. This includes empty food containers, dirty clothes and metal toilet boards.
Since the Columbia shuttle blew up on take-off last year, there has been no trash collection from ISS for nearly two years. The buildup of rubbish on board is making life on board very difficult.
“It's at the point where we have to figure out a way to handle it. It's limiting our efficiency, as we have to move some items out of the way.”said Michael Foale, an ISS astronaut who returned this April.
This year's bad hurricanes delayed the mission, which further increased the problem in the space station. A few weeks ago, two ISS astronauts put some trash into space.
In the past, the Russian Mir Space Station(和平號空間站) regularly dumped garbage bags into space. But now international rules forbid it because the objects could cause dangers to the shuttles. Mir was famously dirty. It came down in 2001 after 15 years in orbit(軌道).
