== Some theory == | |||
While Earth's gravitational force decreases with distance, the Shuttle doesn't reach even remotely high enough to experience weightlessness due to this effect. Rather, for low orbit spaceflight, weightlessness can be understood as gravitational force being balanced by centrifugal pseudo-force. The upshot is that in order to reach a stable orbit, the Shuttle needs to be moving fast - about 27.000 ft/sec, roughly 8 km/sec or Mach 27. | |||
