QUESTION: "Make a hypothesis about how space craft that travel through the solar system obtain the energy they need to operate."

We are studying energy forms in class (Kenetic, Potential, Nuclear, etc.)... i need help NOW!

    You make the hypothesis. The energy to move spacecraft about the solar system usually comes from three widely different sources. (1) The chemical rocket that lets the spacecraft escape the Earth's gravity. (2) A low-thrust, high-specific-impulse electrical engine that operates for long periods to reach outer planets and does not require much propellant. The electrical energy can come from the sun (solar panels) or an onboard radioactive plutonium source. (3) When flying by a large planet such as Jupiter, it is possible to use the gravitational field of that planet to get a "slingshot effect" that increases its velocity, helping it go to planets still farther away. The Voyager mission worked that way, getting out as far as Neptune and beyond.

    Perhaps TchWill see your question and provide you with additional details.

    well my teacher told us to do this as a punishment after we did someting bad but now i understand how to do it.

    1)it moves by a chemical rocket that helps it move away from earth's gravitational(i think that's how you spell it) pull.
    2) a high impulse engine works over a long time so it can be able to go to different planets. this machine does not use propellers. the electrical energy obtained is from the sun using solar panels.
    3) when you eventually get close enough to the planet, its gravitational pull will push you towards that planet's surface.

    i hope these answers satisfy you and i hope my teacher will except them.
