Explanation: A spacesuit floated away from the International Space Station 15 years ago, but no investigation was conducted. Everyone knew that it was pushed by the space station crew. Dubbed Suitsat-1, the unneeded Russian Orlan spacesuit filled mostly with old clothes was fitted with a faint radio transmitter and released to orbit the Earth. The suit circled the Earth twice before its radio signal became unexpectedly weak. Suitsat-1 continued to orbit every 90 minutes until it burned up in the Earth’s atmosphere after a few weeks. Pictured, the lifeless spacesuit was photographed in 2006 just as it drifted away from space station.

说明: 在15年前，一套太空服从国际空间站漂走，不过并没触发后续的调查工作。这是因为每个人都知道，它是被空间站机组成员给推出去的。这套戏称是大空服卫星一号 (Suitsat-1)的废弃俄罗斯海鹰型太空服，在填装旧衣服并配置了小功率的无线电发报机后，被放到绕行的地球轨道上。这套大空服在绕行地球二圈后，电波讯号突然变得很微弱。大空服卫星一号每90分钟绕地球一圈，并在数星期后焚毁在地球大气里。2006年在拍摄上面这张影像时，这套太空服刚漂浮离开空间站。
