Once in orbit, the space shuttle used very little, if any, rocket power to maintain its speed despite traveling over 15,000 mph! How were NASA engineers able to do this?
More mass equals more acceleration
The space shuttle was able to use a special coating in order to achieve its fast speed in space.
Gravity provides the necessary force to keep the space shuttle traveling at a high rate of speed.
More force at liftoff equals more acceleration
