>> No.3299194

actually obama does care for sspace travel. But not the classic kind. Obama is pushing private space companies and shifting nasa more to research rather then actually building rockets.

I think this is a rather good thing to do. What point is it if we go to mars if it's gonne be the same thing like we did with the moon? A one time crap trip that puts 10 people to walk around a bit.

personally I think funding nasa is kind of a waste. I remember after the 2008 market crash, I heard some guy from nasa on washington today I think the show is called. He was talking about a satellite that would see how many stars are in a certain space in the sky. I forget how much it cost, but it was a huge amount. I really wish I remember. might have been like 100 million or even more than that. Just think what that could have done for infustructure in this country? i'm pretty sure it was a lot more than that and all it would find out is how many earth like stars are in a certain area or something. Whats the point? I really doubt we will ever be able to travel to another solar system. A lot of people just seam to assume eventually we will be. Maybe nano technology will give us something that can help make the leap, but thats not guaranteed. To travel to another solar system would probably involve a multi generational voyage. So we'll probably only do it when we can't live in this one any more and we have no other choice. And it could just be a huge gamble.

http://en.wikipedia.org/wiki/Asteroid_mining
>At 1997 prices, a relatively small metallic asteroid with a diameter of 1 mile contains more than $20 trillion US dollars worth of industrial and precious metals.
http://en.wikipedia.org/wiki/Near_Earth_Objects#Near-Earth_asteroids
>As of May 2010, 7,075 near-Earth asteroids are known,[14] ranging in size up to ~32 kilometers (1036 Ganymed).[16] The number of near-Earth asteroids over one kilometer in diameter is estimated to be 500 - 1,000.
http://en.wikipedia.org/wiki/%286178%29_1986_DA
>Asteroid 1986 DA achieved its most notable recognition when scientists revealed that it contained over "10,000 tons of gold and 100,000 tons of platinum", or an approximate value at the time of its discovery of "$90 billion for the gold and a cool trillion dollars for the platinum, plus loose change for the asteroid's 10 billion tons of iron and a billion tons of nickel."[3]

The most practical reason imaginable. Staying alive.
Oh, and an ENTIRELY NEW PLANET with a new geography, untapped mineral resources, closer proximity to the Asteroid belt, the sheer amount of investment and then return from trade between the two planets and the securing of our role as a multi-planet species with far less of a chance of dying out from a random meteoroid impact.

The problem is you assume two things:
1) Space launch vehicles continuously become cheaper for flights to orbit, space infrastructure gets set up, rare earth metals become even more scarce (well, we use a lot of them in pretty much every one of them in all modern electronics ever made.) and omeone decides 'Hurr derp hmm I'm rich and like space, ASTEROID MINAN!' and ends up dominating the market.

Don't say it can't happen:
>Computers will never need more than 640kb RAM
>Automobiles will be something for the wealthy and not for the peasants
etc.

2) Within the next few hundred years capitalism in its present form gets outmoded and transcended much like many forms of economics and governmental systems before simply because technology has advanced to the point where shit like asteroid mining and the vast mineral resources it can provide won't be a bad thing because of its dropping value.

Let me sing you a tale of Aluminium:
http://en.wikipedia.org/wiki/Aluminium#History
It was once considered a precious metal more valuable than gold. Napoleon III, Emperor of France, is reputed to have given a banquet where the most honoured guests were given aluminium utensils, while the others made do with gold.[46][47] The Washington Monument was completed, with the 100 ounce (2.8 kg) aluminium capstone being put in place on December 6, 1884, in an elaborate dedication ceremony. It was the largest single piece of aluminium cast at the time, when aluminium was as expensive as silver.[48] Aluminium has been produced in commercial quantities for just over 100 years.

Welp. Basically everything Inurdaes said.

Also, why does most of this thread seem to have Lord Kelvin's idea of scientific advancement?

"Everything important about physics has already been discovered", Kelvin, 1901.

About 10 years before Relativity, and 20 before Chain-Reactions.

Jesus people.

Not only that but the sheer idiocy...

You know how many people believe the best solution to a killer asteroid, such as Apophis, would be to simply nuke the thing, like every Hollywood movie does? That would just make it worse.

It is Space travel and the resulting industries from it's development that gives us the tools and knowledge to actually predict and counter these problems before they do something silly like kill the whole human race.

The galaxy is likely littered with the long dead bones of one-planet civilizations who made the sensible, economic decision that there was no value in leaving their planet, cataloged and remembered by the few who made the illogical decision.

Both are false. A successor has been chosen and it is, more or less, the alternative to Constellation that NASA engineers themselves cooked up behind Mike Griffin's back when he ignored their concerns about the Ares's pogoing issues.

http://en.wikipedia.org/wiki/Space_Launch_System

And as has been pointed out, Obama's plan is basically Mars Direct plus an asteroid mission, and he's actually backed it with the funding necessary to make it happen.

For some reason people who just hate Obama for being Obama can't bring themselves to accept the reality of this.

This is also false. Even using pulsed nuclear propulsion which is essentially 1960s technology, the trip to the nearest star system would take around 50 years including the time required to accelerate and decelerate.

It isn't bullshit. You believe it is because of what you don't yet know. My estimate, as you'll soon see, was actually very conservative.

http://en.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion)#Interstellar_missions

"At 0.1c, Orion thermonuclear starships would require a flight time of at least 44 years to reach Alpha Centauri, not counting time needed to reach that speed (about 36 days at constant acceleration of 1g or 9.8 m/s2)."

Additionally, I wish to point out that you are arguing against some extremely bright and intelligent physicists who have done a lot of number crunching and math.

Your entire argument seems to sum up as: "It was never built, so it is fake."

But you ignore the fact that the real causes of the program to be canceled were the partial test ban treaty, and alternative but competitive launch systems like Sea Dragon which offered similar payload space while not potentially polluting the atmosphere with radioactive isotopes.

Of course, Sea Dragon went and got canceled too... but that is a different topic.

It is economically sound because it ensures the future growth of our species. There are an enormous amount of resources in our solar system, much more than just Earth holds.

It is foolish to believe that the paltry amount of money we currently spend on space exploration would even 'fix' anything in the world, and it is equally foolish to assume that every single scientist should be working on the cure for cancer or new TV's, or whatever it is you think money is better spent on.

Most of the problems you're referring to are inherent in Capitalism and insoluble under that system. So long as our economic model is predicated upon competition, it will always be stratified such that there are a very few at the top with the large majority at the bottom, living in poverty.

And if we refuse to make any progress until specific social problems are solved, we'll be shooting ourselves in the foot. Why not work on both at once?

Yes youtube video of old guy whining with sappy music is good modern science bro.

Also space is a vacuum, there will be a very small amount of extreemly rapid gas come out of the bomb itself but the vast majority will be radiative energy spanning the em field from low rf to gamma plus alpha and beta. Your wikilink about the metal plate was in an atmosphere where there was an excess of super heated gas to push on it. Which really is quite different. On top of that some experts think the plate was vaporized.

On Orion you could line your plate with water which would super heat and solve your gas problem but this would add a considerable mass cost and if your goal is .1c it really could be killer. I still question the abliaty of the plate to hold up and the shock absorption to function in the speeds required. That's a lot of mass you need to move very fast it just seems indefeasible to me. I'm not usually that scared of radiation but lighting fucking nuclear bombs under you ass... are you mad?

Vasimr is not the most efficient electric rocket when looking at newtons per joule or when you look at isp but all the other electric engines I know of have some interactions with parts of the engine and high volovity particles and those parts ware out quicly. Vasimr uses a magnetic nozzle and is designed to have almost no interaction with the particles so it can be made to theoretically never wear out, making it the only decent high velocity engine I know of that can run for hundreds of years.

Well, now you know better. Orion was checked out by the leading minds in aerospace engineering at the time. It was sound. No matter how crazy it seems to you to use nuclear bomblets for propulsion, that doesn't mean it doesn't work. It's an argument from incredulity.

Here is the plan.

We build genetic synthesizer capable of creating humans and other earth life. We build robots cable of harvesting ore and building structures and shit. You launch a bazillion ships with no one on them all over the two galaxies. The ships arrive at a cool place and the robots start building homes then the dna machines start building the life to occupy the places. You can even have some fly away from earth to return in 100k years to repopulate after the zombie apocalypse or whatever.

If I where sending men to mars for flags and footprints I would not use vasimr, I would probably use an array of hall thrusters. If I where colonizing mars I would use vasimr tugs.
