[:ja]1998年に国際宇宙ステーションISSへの最初のスペースシャトル・ミッションSTS-088で撮影されたスペースデブリです。
宇宙の軌道上にある不要な人工物体「スペースデブリ」は、故障した人工衛星や打ち上げロケットの上段等が、爆発・衝突し発生した破片等の総称です。現在地上から追跡されている10cm以下の小さなものを含めると、推定で５兆8000億個のデブリが地球の周囲を飛び交い、軌道上での宇宙船の活動はデブリの監視なしには困難になっています。

During STS-088 in 1998, the first Space Shuttle Mission to the International Space Station ISS, a photo of space debris was captured.
Space debris is made of man-made objects such as rocket upper bodies, non-functioning satellites, metal fragments, etc. It is a general term that refers to failed space objects, as well as to debris resulting from explosions and collisions. Including small objects under 10 cm in size, there are an estimated 5.8 trillion pieces of debris currently being tracked from the ground in orbit around the earth.
