In space since you donot have to face gravitatational pull that much , a small jet thrust could theoretically enable you to travel thousands of miles.
This is because there is nothing to oppose the velocity that you have attained.
For NAVIGAYIONAL purposes the same fuel of hydrogen and oxygen is used but its required in very small amounts.
For long distance satellites like Cassini etc, Solar power and nuclear power( converted to electricty by thermocouples) is used for operating instruments, communication etc.

in outer space there is not enough sunlight to keep a spacecraft alive with solar panels.
In this case a so called Radioisotopic Thermal Generator is used getting energy out of slowly decaying radioactive elements.
Cassini and New Horizons have such RTG's which have already been used by,- for example-, Pioneer and both Voyager spacecraft.
