Voyager 1 & 2 Unidentified Signals

Its pretty ironic that in the future we may actually be capable of flying out to it and picking it up in a couple of hours or so....Just like in ED...
Will we think......What a waste of time and money that was as we hurtle past it :)
 
Go to Sol, and fly to it - a bit over 2 million Ls.

weird. that's how i found voyager 1. 2 was 0.12Ly from that one for me. over an hour in real time to visit both, i am glad the ships keep flying when you alt/tab and do something else, not sure if i would have had the patience otherwise.

Hmm, I didn't check the exact value 2.1M or so Ls, and I was around Pluto when noticed it - might have something to do with LY/Ls flip. Although, 0.12 LY'd be over 3.7M. Hmm...

starting positions probably played a part, i followed the instructions from https://forums.frontier.co.uk/showthread.php?t=77734&highlight=voyager for voyager 1 so started from Galileo. voyager 2 was pure luck from voyager 1. oh well, we have a range of instructions for everyone else now :)

good luck with catching up with something that's atm nearly 15 (if my math is not too far off) light-hours from earth 'in a few hours'. i highly doubt that in the next 100 years we'll have a manned space craft capable at travelling at 1 % of the speed of light.

Solar sails that could theoretically be built with today's technology could reach a significant fraction of the speed of light, if assisted by orbital mirrors or lasers. Would still take quite a while to accelerate though, certainly longer than hours.

Anyway manned spacecraft wasn't specified, nor was a time table other than "future".

No. We learned quite a bit from it, and without such steps progress would never be made. I don't scorn Galileo's first telescope as a waste even though my own is orders of magnitude better; I recognize it as the phenomenal achievement that it was, and know that without that step, I'd never have what I have.

Don't think it was a waste of time, whithout the actual launch we simply would not be in space, it is a stepping stone to greater things.

You guys took that way too serious.

-solar sails are a one way trip away from the sun.
-a solar sail big enough to 'carry' a space ship big enough to 'house' astronauts for a considerable time would take a huge amount of time to ship into space from the earth (dozens of years with current tech, maybe centuries just to get the sail in space).
-orbital mirrors would take even longer to get up there, lasers that can push a space craft would take more power output than the total power output produced by humanity atm...
...
i think it's a safe bet to say that no-one alive today will ever travel at 1 % of the speed of light.

true on both accounts :)

i think voyager 2 is one of mankind's greatest achievements yet :)

and afaik, it seems that any 'living' race might be forever confined to it's own solar system of origin. only robots dormant for aeons of travel, outliving the species that made them, might ever stand the chance of reaching another star.

No they aren't, though any inbound trajectory is going to be slower than outbound...once you get far enough away at least.

This conclusion relies on two assumptions that I find rather presumptive. That it will take n time to for the technology to become practical and that everyone alive now will live less than n.

atm we have 2 technologies for moving stuff in space. slingshotting between gravity wells and ejection of matter at high speed in the oposite direction of the one that one is travelling. there is a limit on the mount of matter for ejection and fuel for energy that a ship can carry which limits the amount of velocity increase a ship can obtain once in space.

any sience fiction 'tech' is just science fiction untill proof of concept. and for most of the science fiction stuff, we don't even have theories about how it could be done, let alone a tech. it's like talking about rockets ... before the ancestors of our species mastered fire.

may i remark that humanity only made the most modest advancements at best since apollo/saturn and not a single operational technological advancement when it comes to space ship speeds ?

a man to mars and back to earth in my life time ? ... maybe, but i doubt it.

something that will overtake voyager 2 in my life time ? unlikely imho.

i hope i'm wrong :p
