what does a space probe carry
There is no active galaxy that is effective in the intergalactic space probes. No space probe has ever traveled as far as the next nearest star outside of our solar system.
a space craft
As space probe is carried into space using rockets and afterward can maneuver using thrusters, sometimes gaining speed using the gravity of a planet. Once a space probe has been set on the right trajectory it does not have to do much; there is no air resistance to slow it down and gravity from the sun and planets is already taken into account.
