Astronauts on the space shuttle Endeavour bid their final farewell on Sunday, floating out of the International Space Station before making their journey home.
航天飞机奋进号的宇航员周日发出他们飞行的最后告别，在返回地球之前在国际空间站外面飞行。

Shuttle commander Mark Kelly thanked the ISS crew for their help after they successfully installed the Alpha Magnetic Spectrometer, which Kelly called "a remarkable thing for physics and for science." Endeavour delivered the two billion US dollar cosmic ray detector that will remain on the space station for the next decade. The shuttle will undock from the ISS later on Sunday night and begin its two-day journey home.

It's expected to return to Florida in the pre-dawn hours of Wednesday, never to fly in space again. The shuttle will be retired to a museum in California following the 16-day mission, its 25th.
