太空中群“星”闪烁,一派繁忙景象,卫星与卫星相撞的“交通事故”时有发生。1994年,一枚法国报废火箭发动机上的碎片,击中了一枚名为“樱桃”的法国卫星,切断了卫星上测量重力梯度的装置,使卫星运行超出正常范围。1993年,由于微小流星体的撞击,致使美国“奥斯匹林”通信卫星上数百万美元的电子设备失效。这些典型的太空交通事故告诫人们:架设太空“红绿灯”,加强对卫星的交通控制,势在必行。
The “stars” of the clusters in space are twinkling, a busy scene, and “traffic accidents” in which satellites and satellites collide. In 1994, a French scrapped scrap on a rocket engine and hit a French satellite named “Cherry”, cutting off the gravity gradient measuring device on the satellite and making the satellite out of normal range. In 1993, millions of U.S. dollars worth of electronic equipment on the U.S. “Ospelin” communications satellite failed due to the impact of tiny meteoroids. These typical space traffic accidents tell people that it is imperative to establish space traffic lights and strengthen traffic control over satellites.
