How fast does a space shuttle go per second?

A:

It depends what phase of the mission you're asking about. In orbit with the International Space Station, it's travelling over 17,000 MPH.

At Launch, T+30seconds it's travelling 500MPH/2miles in altitude. At T+1minute it's travelling over 980MPH/6 miles in altitude.

Around T+8minutes, MECO (Main Engine Cutoff), the shuttle has reached a speed 17,000MPH at 65miles in alt. More info can be found at http://www.NASA.gov/home/index.html
