Expert Answer:

Attaining zero friction is very difficult as matter exists everywhere on Earth.
 
However, creating a vacuum chamber will reduce the friction to a greater amount.
 
Rockets stop in space by firing thrusters in the opposite direction to the direction in which they are travelling.
 
This will create a force in the opposite direction, thereby enabling them to stop in space.
