Whoa, okay. Satellites have detected ion thruster activity, guys.

卫星已经侦测到离子推进器活动了 各位。

Its ion thrusters put out less force than it takes to push a single key on a keyboard, but it accelerated to over 11 km per second by firing that tiny engine for nearly six years.

它的离子推进器产生的力比按下键盘上的一个键要小，但是通过点燃这个微型发动机将近六年，它加速到每秒 11 公里以上。
