Expert Answer:

The momentum of a rocket before it is fired is zero. When the rocket is fired, gases are produced in the combustion chamber of the rocket due to the burning of the fuel. These gases come out from the rocket with high speed and the direction of momentum of the gases coming out is downward.

Thus, to conserve the momentum of the rocket and gases ,the rocket moves upwards and continues to move as long as the gases are ejected out of the rocket.
