Do all spacecrafts use their fuel in their entire journey? ?

like voyager 1, did it use its fuel during its entire journey to a specific planet?

    No. Most spacecraft just coast and use occasional bursts of thrust for course adjustments.

    Spacecraft use fuel to lift off Earth and to get into the proper trajectory. Then their fuel is almost used up. They follow a free fall path all the way to their destination. A tiny bit of fuel is used to adjust their trajectory or to put the craft into an orbit around a planet.

    They use solar wind, solar power, fuel, gravity assists to get further and further. Even if it runs out of fuel, gravity still exist so it will be under a force at every time. Gravity is infinite.

    Voyager 2 made a final trajectory adjustment in 2012, and determined not enough fuel remaining for anything else. Now just coasting in deep space at 33,000 MPH.

    New horizon has enough fuel yet to get another slingshot out in the Kupier belt.

    There is no booster on these crafts, only maneuvering rockets with very limited fuel.

    Apollo kept its booster with fuel for return and orbital insertion getting home. Jettisoned, it had a retro package for re-entry. Probes lack all that as they are not coming back.

    No;  Most spacecraft burn for a very short time to increase speed or change trajectory, then they coast... Apollo, for example, burned about 12 minutes to reach orbit; then, they burned again for about 5 to 6 minutes to gain speed to go to the moon.  

    Voyager, Pioneer, New Horizons, etc., they all burned almost the entirety of their fuel leaving Earth orbit, headed for Jupiter - then, small maneuvering jets would 'nudge' the craft onto the correct trajectory if needed... but, for the vast majority of their flight - they use no fuel.

    space craft  only need fuel to change direction  once they get moving   or  to change speed

    No. The voyagers used inertia, momentum, and gravity assist trajectories around massive planets to accelerate their speed, the planets rotation rates and angular momentum slowed down a miniscule amount. Yes, some maneuvering fuel was used, but NOT continuously. There is very little drag in space, no air resistance.

      ????.You don't think those gravity assist trajectories have NOT been calculated well in advance.? That's pretty unbelievable.  Magellan used gravity assist trajectories and the last maneuvering fuel was used to crash it into mercury, not Venus.
