lord_seagrave Posted July 4, 2016 Report Share Posted July 4, 2016 It's probably a really dumb question, but with the billion-mile+ journey of the Jupiter probe, I was wondering why we humans aren't building large-scale interstellar vessels? Does anyone here have the answer? LS Quote Link to comment Share on other sites More sharing options...

Lloyd90 Posted July 4, 2016 Report Share Posted July 4, 2016 What for ? How would it benefit us ? It would be monumentally expensive and non-profitable. When they discover trillions worth of resources on other planets we will start building them. If we haven't gone extinct by then that is ...

keg Posted July 4, 2016 Report Share Posted July 4, 2016 Good point, a bit like North Sea oil.Always there but took increase in oil price and improvement in technology to make it viable. Same applies. Quote Link to comment Share on other sites More sharing options...

four-wheel-drive Posted July 4, 2016 Report Share Posted July 4, 2016 In short to expensive and to many problems to overcome today but it will come I tend to think we should concentrate on unmanned missions in fact the way that computers are progressing with AI it is just so much simpler to send machines as they do not need air food exorcise etc etc then perhaps some time in the future when we have developed more advanced craft then perhaps we can try again.

FalconFN Posted July 4, 2016 Report Share Posted July 4, 2016 6 months to mars on 1 way trip..... Until some sort of either ram scoop or faster than light drive is developed return journeys won't happen.+1Interstellar journeys, even at speeds orders of magnitude faster that we are able to currently go, would take many decades to even the closest stars. It would cost trillions and would have a high chance of failure. Until we understand the true physics of the universe we won't have a hope of covering such vast distances easily.

VULTURE Posted July 4, 2016 Report Share Posted July 4, 2016 Just out of curiosity, what's stopping me from building a spaceship and leaving this planet,is there a law or something that would get in the way? I suppose you would have to let the local air traffic controller know that an object would be appearing on radar for a minute or two. I presume I have to wave my passport through the window as I pass the ISS, I must be bored lol Vulture Quote Link to comment Share on other sites More sharing options...

robbiep Posted July 4, 2016 Report Share Posted July 4, 2016 The reason for no interstellar flight is simple : time. The quickest Jupiter probe took just over a year to travel there. Jupiter is roughly 380 million miles from earth. The nearest star (not counting the sun) is roughly 24,925,371,500,000 miles from earth. Which is 65,000 times as far. So at current spacecraft speeds, the trip would take about 70,000 years. Each way. Quote Link to comment Share on other sites More sharing options...
Dougy Posted July 4, 2016 Report Share Posted July 4, 2016 What I can't understand is back in the late 60s they transmitted live TV from outer space from a planet . And in colour. I think it was the clangers Surly they could build a space ship that could travel to the moon with a load of building materials and knock some houses up.

martyn2233 Posted July 4, 2016 Report Share Posted July 4, 2016 Do we really need to go into space? Think we the human race has screwed the planet up enough never mind taking junk up there as well Quote Link to comment Share on other sites More sharing options...
Rewulf Posted July 4, 2016 Report Share Posted July 4, 2016 Our biggest problem when we try to leave this world is..gravity. Although most on here will say that they understand how gravity works, that is not the full picture,gravity is a theory,even our best scientists dont really understand it properly. Once we can overcome its effects,or even reverse it, so it repels (Think 2 magnets ,south to south,or north to north) we are wasting resources on trying to escape it. The drive system for whatever craft you would use is then the next obstacle. Photon,anti matter/matter ,fusion or solar sail ! Whichever,you need to be pushing for something approaching light speed,otherwise your crew are going to have to pro create. Because as robbiep said ,time is your greatest enemy out there. The final conundrum ,why ? Resources ? The solar system is full of them,if you can find a way of getting them back home. New Earth ? To me the only sensible reason,but any colony would need a planet so much like this one (atmosphere,gravity,weather ect) it would be highly unlikely to find one in a neighbouring system,you might have to travel 30+ light years to get there.

old'un Posted July 4, 2016 Report Share Posted July 4, 2016 The answer to future space travel is a very, very, large space station (city in the sky) with centrifugal gravity which is possible, part of the experiments carried out on the space station are with this in mind, a moon base is no good because the lack of gravity, mind you it is possible for man to live on the moon but its unlikely after being there for a number of years he could return to earth because gravity would certainly kill him.

jam1e Posted July 4, 2016 Report Share Posted July 4, 2016 (edited) We can't afford to build them! Were too busy giving other "poor" countries like India huge amounts of money, so they can, and have built their own...

malkiserow Posted July 4, 2016 Report Share Posted July 4, 2016 We need to be part of larger consortia to build this kind of kit. We are very good at it but that was linked to strong university research outputs, let's hope we continue to be strong in supplying satellite and space kit. We are members of ESA Quote Link to comment Share on other sites More sharing options...
amateur Posted July 4, 2016 Report Share Posted July 4, 2016 It's already been done - surely Stanley Kubrick had already built a space station in 2001 and I'm sure that the USS Enterprise was travelling at warp-speed to meet the Klingons, or was that the Klangers Quote Link to comment Share on other sites More sharing options...
