    Whatever happened to them? Are they out of our solar system or something? You just don't hear much about them, and I'm interested on how far they went, you know. Are they having a visit with our degraded friend Pluto by any chance?

    They are both still working [just] it seems they may carry on for another 10 years. When they were launched it was not clear we would be able to communicate with them at the outer solar system - however advances in receiver technology & sensitivity (as well as digital processing) mean we will be able to keep track of them until either the propellant runs out (and they can no longer keep orientated to earth, or the RTG degenerates to the point where it can no longer power the transmitter.

    Voyager 1 has hit the 100AU mark (Aug/Sept 2006) and there is some discussion as to whether they have/will soon hit Interstellar space. Go to NASA web-site for other details.

    I forgot the Pioneers had been launched. It says that they don't function anymore: what happened?

    Will the Voyageurs be able to capture the light of other stars to power themselves? Because if that is so then they could go on for a while.

    And what to you think of the New Horizons? How far do you think it will be able to go with new and improved technologies, better PV cells, and more effecient propellants?

    The Voyagers can't use light to power themselves. They use RTGs for power, not solar cells.

    Oh, OK. What are RTGs?

    I'm curious about what is going to happen to the first one when it leaves the solar system and gets into the interstellar wind.

    It's a pile of 'hot' material - the heat is used to generate electricity.

    We'll probably just get a polite letter from our neighbours asking us not to chuck stuff over their wall. :wink:
