In the 1950s, rocket scientists dreamed of atomic-powered spaceships. Now these far-fetched designs might help a new generation explore the cosmos.
If we are to advance in space nuclear is the next step. We as a society need to get over the nuclear stigma that we have now. When used correctly and safety measures are in place it is the far better option. In space alone nuclear would be much more efficient compared to the combustible fuel that is used now. We can power rovers with nuclear energy, why not our space ships?
@Event_Horizon. You are right, nuclear power will be great for the solar system but the closest star is 4 light years away. So no it wont take us to the stars.
Atleast someone understands physics here. Even if you take all the nuclear fuel in the world and try to use it in the most efficent way possible, even then it would take 1000s of years to get to the nearest star not to mention the technology required to make a vessel capable of such speeds. If someone still thinks that nuclear rockets can get them to the nearest star then either they know how to hibernate or they must be immortal.
Nuclear power is a decent idea but the concept of traveling at the speed of light doesn't make sense. By the time we reach our destination, we would have significantly aged. The only way I could see space travel making sense is if we bend space to link separate segments of the universe via portals.
...we're gonna need magic on this one.
There's lots of research being done already on FTL travel at NASA. Such as Alcubierre’s "Warp Drive" and "Negative mass propulsion", to name but a few. If NASA are trying to make the science a reality, then I'm fairly sure that other organisations that are public or unknown are looking into this. Institutions realise that once you achieve FTL travel, then time travel is also possible.
Wow, congrats with an even less likely solution.
Sorry, but I don't want to spend 30 years of my life making one trip to another solar system. Linear travel in its present state is not a plausible solution.
Racer, good news. You won't! Someone else will be making those long trips and likely not even in your lifetime or your childrens lifetime. Get used to the the tech that is available today and what may be possible in the next 50 years. Humans traveling to another solar system will not be an option. Not only will there always be technological roadblocks there will be political. Politics will both stall tech advancement and exploring when the tech has matured. This is the harsh truth.
I'm just saying we should be looking at alternatives to the current mindset of long distance space travel. Here's an interesting read in the mean time. http://www.space.com/21675-...
actually theoretically if you were to move at the speed of light, you would experience time at a different pace than everyone else. to you it wouldn't have been say 30 years, it would be significantly less, and you wouldn't have aged much if any at all. it's all about relativity.
True, but let's say you get back home. Your friends would soon be years older than you and a whole generation could pass by depending on how far out you fly.
@Racer-x - Time to bring Nikola Tesla back alive for that idea
Once they are able to shrink a nuclear fission reactor to a small enough size, Ad Astra's Vasimr magneto-pulse engine can get up to 100,000 mph.
Speed is one problem. Mass must be negated to prevent catastrophe.
"lol" Not fast enough! We would need to have a propulsion speed of 12% to 15% the speed of light to get around our galactic neighborhood in a human lifetime! There are a quite a few stars within 10 light years that are good candidate's to explore, one being "Tau Ceti" Which is a similar star to our sun that also happens to have a planet in it's habitable zone "whether there's life or not is speculative" Our best place to start is right in our back yard! Alpha Centauri A and B are the closest to our sun in size and composition, add to the fact that scientists have found a earth size planet around one of them "although too close to support life" guarantees that would be our first stars on our exploration list!
I am referring to things that we have right now that are viable, of course 100,000 mph is only a fraction of what we need.
"Will nuclear-powered spaceships take us to the stars?" Why go there, won't we burn up within it's radius? :P
I'd like to believe we have other means at our disposal than something as critical as nuclear power.
Maybe we're not meant to. As for nuclear, it's not going to take us to the stars. The only way space travel that far would work is for younger people to take the journey on a massive ship and keep having children throughout the years.
They should use THORium
