How fast does the international space station travel?   The International Space Station travels in orbit around Earth at a speed of 17,500 miles per hour (that's about 5 miles per second!). This means that the Space Station oâ¦rbits Earth (and sees a sunrise) once every 92 minutes!  .
1 1 light-year is 5.8 trillion miles and the maximum speed of a NASA Space Shuttle is 17,500 miles per hour. 2  The fastest unmanned space craft traveled 157,000 mph. 3  At that rate, there and back would take only 8,500 earth years. 4  So if you were a Mesopotamian farmer in 6,500 BC, you'd be getting home right about now.
