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。
Though designed during the 1950s, this rocket-powered research airplane set speed and altitude marks that were not sur-passed until the advent of the shuttle.
虽然它是在50年代设计的，但这种火箭动力飞机的研究标志着它的速度和高度直到航天飞机出现后才超过。
With snail clench solid is on lower shaft, with 2nr/min (N is embroider engine rotate speed) shuttle of rotate speed edge wears the annular slideway C that go up (oriented tine) high speed runs.
用螺钉紧固在下轴上，以2nr/min（n为绣花机转速）转速沿梭架上的环形导轨C（导向齿）高速运转。
