After circling Earth twice, it would slam back into the atmosphere at more than 20, 000mph (32, 000kph), eclipsing the 17, 500mph (28, 000kph) speed of a returning space shuttle.

该探测器绕地球两圈后，再以20000英里（32000千米）的时速重返大气层，该速度超过了时速为17500英里（28000千米）的返航太空船。

This is not a speed you will sense, as in G force when a shuttle takes off from the surface of the Earth.

就如航天飞机从地球表面升空时，其力量是以“G”计算的，因而这种速度你是不能感知的。

But scientists at the NASA space center have developed a gun built to launch dead chickens at the windshields of airliners, military jets and the space shuttle, all traveling at their top speed.

但是，在美国航天局航天中心的科学家已经开发建成发射的客机，军用飞机和航天飞机的挡风玻璃，所有在其最高速度行驶死鸡一支枪。
