A prograde orientation is one that has the ship facing in the same direction as it is travelling in its orbit.
A prograde burn is one in that direction, i.e. that adds to the ship's orbital speed.
The effect of a prograde burn is to raise the orbit's altitude (opposite the ship's current location); it is thus used when moving to a higher orbit, or when leaving a planet or moon completely.
