about 25 minutes
before the shuttle reaches the upper atmosphere.
Does Rocket return to Earth?
How does a rocket reenter Earth?
When an object — with blunt-shaped surface facing down — comes back to Earth, the
blunt shape creates a shock wave in front of the vehicle
. That shock wave keeps the heat at a distance from the object. At the same time, the blunt shape also slows the object’s fall [source: NASA].

The solid-fuel rockets have their own disadvantages, Once the fuel in the solid-fuel rocket begins to burn, there is no way to
slow it down or turn it off
, So, some of the most dangerous accidents that can occur with the rocket are those that involve solid-fuel combustion that gets out of control.

Whats the fastest we can travel in space?
But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than
300,000 kilometers per second (186,000 miles per second)
