shouldn't we really be trying to create a 'warp' drive instead?

The Orion project (as everyone _should_ know) would be the way to get (LOTS of stuff) around the solar system.

Great for lifting battleships to orbit!

ttfn

flames because rockets have lots of them.

Nuclear to Mars? Not more "Little Green Men", phleeeeze! They'll be really pissed off. We're lucky not to have woken the basta*rds up with the (relatively recent) armada of unheavily armed solar-powered Golf Carts.

Where's Orson Kaart (or whatever the bloke's name was) when you need him?

Icon obviously, natch.

Well why not nuclear - if we cant get enough energy from that big nuclear explosion in the sky - why not make our own - safe, secure - tiny one. Then when we finally lick this fusion tech, in 30 years or so, we can use that.

Alternatively we can spew out CO2 and water vapor into space - think of the damage that will do to the interstellar evironment. Interplanetary warming!!!!! Think of the children... little green ones.

You need the impulse drive first.

The scientific community currently lacks any insight as to how to overcome Newtonian physics limitations that arise once velocity starts climbing closer to c. Until there is found a way to bypass or overcome this limitation (be it by space-warping, alternate spaces, or whatever), viable FTL transport remains strictly the realm of science fiction.

Here's one, or at least a mathematical model for one.

Sure, The problem is it's a much longer way off as we don't have a clue yet how to bend the fabric of space....without a massive amount of gravity. oh like one hundred times that of the sun.

Warp drive was based on the concept of creating a pocket of normal space, inside a warp bubble, which was essentially the layman's term for said pocket of space. Outside the bubble space would be shooting by at FTL (Faster than light) speeds. However inside said bubble it would be static. The theory being that in this sence it would defeat Einstain's theory claiming that to reach light speed one requires infinite energy, and attains infinate mass.

For real!?

Hell to Greenpeace, lets get those dustbin fission nukes up into space TODAY!

I mean isn't space filled with deadly radiation to begin with? I'm sure one little fission reactor is like adding a drop of water to a billion oceans.

It can't be too difficult to design a fission reactor that is rendered totally safe until armed in space, and its debris port pointing squarely AWAY from earth.

Bagsy shotgun on the first 39 day trip to mars!

Random Schwartzenegger quote : "Get your ass to Mars.", name that film.

Look guys, don't write this stuff. Don't raise my hopes that we have any higher aspirations other than to completely cover this mudball of ours with concrete in order to appease the modern four-wheeled Gods.

The Establishment has successfully killed off the will to embark on any form of risk-taking activities such as space exploration etc. The last opportunity for putting the big ideas into practice was in the Sixties and we blew it. OK?

Suppose you get to Mars. What are you gonna do with it anyway? Another big mess? Got any plans to provide an environment where people can grow, create, develop? Of course not.

And what do we have on this thing? A cuisinart???

_Ad_ Astra? Is this the Google influence at NASA?

Why do 'artists' insist on putting wings and vertical stabilisers on spaceships - there is no air in space dumbwits.

They should have it built as a large cube - works for the Borg - functional and respecting awe and fear from other species.

All hail our new Borg overlords as they assimilate us.....

I thought bees have shown that the hexagon is more efficient that the borg square squared.

I for one welcome their buzzing overlordship...

Sorry to go off-topic, but I lost it part way through the first sentence in article and skipped straight to the comments.

Part of the issue be it armed/activated or not is that we still need to shoot off this fissionable material into orbit. And the last time I checked, be it government funded or private, the inherent risks of getting anything into orbit is very very high. Nobody has a 99+% launch success rate... every single rocket launched risks a butt-load of cash if not a few lives that the thing won't go BOOM 90sec into the flight. When it does go boom--not if but when--no company or administration wants the literal fallout of nuke material showering down on all of us. I know we have hundreds of warheads poised to do just that, but that was by design not by happenstance as this would be.

Don't get me wrong, I'd love it. I think space is a great environment that is well suited for nuclear energy. We just need get much much better at getting things up there.

Those are neither wings nor stabilisers: they are solar panels, built so that some are always pointing at the best available angle towards the sun.

Its only a matter of time before we work out how to harness this hidden force of nature that I alone know about bwahahaha. Then we shall ride to the stars together my Earth bound friends, surfing the universe for ever ...

You need to be anchored in space & time.

You need a stasis field..

Slow down or Stop time for your ship/vessel/cube thingy.. then start it again when then earth has moved on a bit.

As time would have stopped for the ship, it would be anchored in it's point in space and would be yanked out of orbit as the earth moves around the sun.

Hey presto, no longer on earth and you've got 12 months to get your nuclear engine up and running before the earth comes around and smashes you..

Captain: What happen ?

Mechanic: Somebody set up us the bomb.

Operator: We get signal.

Captain: What !

Operator: Electric engine turn on.

You are correct in that it is not wings that is depicted in Dr. Chan-Diaz's artist's conception. Your first conjecture, that they are waste heat radiators is almost certainly the correct one- with a 10 megawatt nuclear plant, there is a LOT of waste heat to get rid of and very little need for solar panels (which would be near useless by the time you got to Jupiter what with solar power falling off as distance squared). As for why they are shaped like arrow feathers, I would wager that the 10MW nuclear power plant uses a shadow shield to keep it from irradiating the rest of the spacecraft. The angling of the waste heat radiators serves to keep them in the "shadow" cast by the shield placed in between it and the reactor, which is otherwise left unshielded to save on mass.

Here are links for waste heat radiators:

and radiation and shielding (including shadow shields) in the context of nuclear rockets:

The Star Trek Voyager was a sexy Space craft. Just because its OK to build a box doesn't mean we have too. Do you really want to get to another species in a box? Thats like trying to look cool in a minivan.

as some one pointed out warp dirve is about a bubble of normal space around a vessal but they missed that you then compress the space in front of said bubble and expand the space behind. not sure who thats supposed to work something to do with artifical gravity and magnetism. your then travel over the compressed space using a more conventation means ion drive etc (star treks famous impulse drive was supposed to be ion refusion drives) these relative to the ship speed was only 1/4 of the speed of light (impulse drives topspeed but probable self limited by ship builds to stop the time dilitution effect being to bad) while to the rest of the universe yours traveling faster than light

of and the warpfactor is the factor of compression once you reach warp factor 10 supposely you can go compress the intire universe to a degree you can go anywhere personally i think that's a bit stupid.

on of the reasons given for no warp in a solar system is compressing the space in which a star is would me either a start in your face or possible prature super nova neither good for a starship.

yes i know this makes me a total treky nerd but when i was younger like physics and start trek so the science of star trek book was out so read that.

ok i'll get my coat

Was originally supposed to feature nuclear thermal rockets. Then Kennedy said "Moon. Now." and the project got dropped.

Speaking of the Saturn V, it does have a 100% success rate. It's even powerful enough to get nuclear flasks into space.

Mine's the one that says "Mars or bust".
