    Once both spacecraft run out of power - expected sometime after 2025 - they will continue roaming through space.

    Why does thinking about this make me a bit sad?

      They will likely be the last evidence that the human race ever existed.

      In 2-3 billion years the sun will leave the main sequence steady state it has been in. This will end in it turning into a red giant, and engulfing earth and destroying all record we existed.

      Meanwhile, the journey of Voyager 1 and 2 will have only just begun. They will continue moving through the expanding universe for at least 3,000,000 Billion years.

        If we are lucky the earth might survive after the sun becomes a red giant. As the sun expands because its gravity is weakening which means the hold on earth will be weaker and the earth will move away from the sun. Hopefully the speed we move away is equal to or faster than the suns expansion.

        Wouldn’t friction (however little in deep outer space) eventually decay the crafts way before Earth is engulfed by the Sun?

          Interspace is empty on a level that is hard to imagine.

          There are 2.652×10^25 molecules in one m^3 of air.

          That is 26520000000000000000000000.

          In intellar space?

          The is 1.

          IE: the probe would hit more atoms in one second on earth moving at 1 m/s than it would travelling the entire age of the universe so far through interstellar space.

          Even the space between the planets is thick with matter by comparison.

            I don’t think this comparison is really valid. If you are going through the molecules of air at the speed voyager is currently going it would vaporize. If you’re comparing it to more terrestrial speeds, It also ignores the amount of energy imparted by that 1 atom due to the high velocity. The high velocity also means it encounters those singular atoms and a higher rate.

      If we take a moment to anthropomorphize Voyager here - It kinda is. Think of the pure vastness of space. Remember that all of the planets in our Solar System can fit between the Earth and our own Moon with a little space to spare.

      Look up to the sky, point in any direction and (with the magical ability to fly up and through space) go in that direction without changing course, and there is an almost 100% guarantee you will never run into anything. Sure you may see things go by as you travel, but its just…never ending travel, fast as shit, through endless space until you just…stop and die.

      Voyager’s just gonna keep going, and going…and going. It’s material will eventually break down I assume, due to exposure, and perhaps fall to pieces, but…it’ll keep going.

      The cool thing about Voyager is that it has a record of information about Earth, etched in gold, with instructions on how to read the data it contains back.

      Even once it powers down, it’s still on a mission. If millions of years from now intelligent alien life ever encounters it, they will know who we were and that we existed.

      It’s our handprint on the cosmic wall.
