    In 1.875 billion years, Voyager 1 in its own reference frame if it is travelling towards the Andromeda galaxy will reach it. The signal of any pictures will take 100,000 years to reach us provided that we can still pick up those signals and that we are still on Earth. Cool huh?

    The signals of Voyager however have been becoming weaker and weaker since it left our solar system. Who knows why. Maybe we'll find out what it means to leave sol's domain.

    But will voyager's nuclear power cells be functioning in 1.875 billion years? Probably not.

    It is just about possible to receive signals from a spacecraft at 1/600 of a light year using a large parabolic dish on Earth let alone 1 light year.

    And 100,000 light years..... well.. you would a transmitter of the power of err.. 3.6 Million GW ... about 60,000 times the ouput of all the UK's power stations.

    You mean quick opinion! (sorry, I've just always wanted to do that).

    Anyway, I agree. Voyager won't make it. On the improbability that does though, I'm sure General Electric would be very interested in a machine that doesn't break down after 1.8 billion years.

    If they are, will anyone still be around to receive the signal? Human survival over the next 1000 years alone is looking bleak.

    Have you been watching the news lately? 1000 years is pretty friggin generous. I would like to think that we have to potential to last that long, but without some major revisions, humanity will be a failed experiment a lot sooner than that.

    A lot of people SAY that about revisions, but so far I've gotten none to agree on any suggested ideas. Even on something as simple as a rational vocabulary change. :?

    Was Voyager the one with gold record with recording of earth sounds?

    I wonder if it will make the "top 10 list" in Andromeda galaxy?

    I'm curious... what kind of things have you suggested?

    I've suggested many things to people on and off this forum. Ranging from cultural reforms, to entire worldwide plans for shrinking our bloated population, to simplistic ones like fixing our broken grammar system. Granted, not all of them are feasible or accurate, but I'm trying. :?

    From memory Voyager's power has shrunk by around 35% in the 30 or so years it has been racing away from us - since it is a radioactive power source it will continue to decay at 50% every 45 years or so;. Almost all of it has already been shut down to conserve power. The best estimates from NASA indicate there will no longer be power to receive or transmit after about 2020 at which time it's on board systems will no longer receive the commands necessary to continue pointing it's antenna's towards earth.

    After we're all dead (hopefully not) the only message humankind will ever have is that of a floating disk in space, with a message from Jimmy Carter. And the British will only be remembered by a number of 16th century dance musics with a French name :? oH The irony.

    Your numbers seem to be a bit off. Andromeda is 2.5 million ly distant at present and will make its nearest pass by(or collision with) our galaxy in 3 billion yrs. In 1.875 billion years, this distance will have shunk to a bit over 1 million ly not 100,000 ly. And in 1.875 billion years, Voyager will have only have traveled about 100,000 ly, leaving it 900,000 ly short of Andromeda.

    It was just a quick calculation anyway off that universe video on Youtube. I thought it might be a good estimate given I just did regular multiplication, but thanks for clearing that up for me and everyone else :-D

    Did anyone ever think that (if the human race is still around) we might one day have the technology to go and retrive Voyager-1?

    I saw something like that on Star Trek: Voyager where it somehow ends up in The Delta Quadrant. Also Something similar on Futurama (on the windscreen of the Planet Express ship). It will either be gloryfied or forgotten as most things with our history. But yes one day we may be able to reach it, I personally however would not like it to be brought to a museum. Who knows if we can still make more use of it and make all our sattelites working?

    Yes, it also featured in one of the Star Trek movies (can't remember which one). The Klingon's destroyed it.

    It was the first one (the motion picture) and was one of the best.

    I aggree totally! It should be allowed to continue to travel as intended. Maybe there will be regular flight's to go see it but not interfere with it... (note to great-great-great-grand children - There's money to be made in ancient space attractions!! )
