First Details of Manned Mars Mission From NASA
OriginalArlen writes "The BBC has a first look at NASA's initial concepts for a manned Mars mission, currently penciled in for 2031. The main vehicle would be assembled on orbit over three or four launches of the planned Ares V heavy lift rocket. New abilities to repair, replace, and even produce replacement parts will be needed to provide enough self-sufficiency for a 30 months mission, including 16 months on the surface. The presentation was apparently delivered at a meeting of the Lunar Exploration Management Group, although there's nothing on their site yet."
We could have been going in 5 years instead of 25 if we as a species/world community had better priorities.
(example: 500 billion in Iraq, more than enough to fund the complete development and production of everything that would be needed)
We were kinda missing a fully-committed competitor for prestige and bragging rights, like we had when we were pushing to the Moon in competition w/ Russia.
Also, nothing (aside from a metric assload of money to go with the initiative) is stopping private interests from giving space a shot. Although there is a lot of work being done in that direction (Scaled Composites, Armadillo Aerospace, etc), I fear that most will stop cold or die off before they really get things going full-time, and some appear to be stopping short just on what they've done - e.g. Scaled Composites may become just a neat-o space tourista thingy to get into sub-orbit, but otherwise won't bother any further.
But then, I'm prepared to be pleasantly surprised and proven wrong when it comes to this ideal.
(Hell, the only reason NASA appears to be getting back into the manned-mission-to-space thing again is because the Chinese got one of their own into space, and Russia+India want to put folks on the Moon... kinda sad that it takes ego just to get people working towards what should be a solid ideal in the first place).
All that said - someone call me when an average guy can get into space without spending a shitload of cash or his whole career kissing bureaucratic arse.
Quo usque tandem abutere, Nimbus, patientia nostra?
The funny thing is, the longer they wait to launch a human mission to Mars, the smaller will be the advantage compared to a robotic one. Spirit and Opportunity can already do a lot of exploration on their own but, currently, humans, could do a lot better, faster, etc. I'm not so sure that this will still be true in the 2030-2035 time frame. Regardless of the state of AI then, robots will be a lot more autonomous, capable of fairly advanced decisions and exploration capabilities. And they will be immensely cheaper to deliver to Mars (and anywhere else for that matter). So, the longer they put a human mission off, the least sense it makes.
It would have been an interesting article if it had gotten into how this "cryogenic" propulsion system will actually work. The biggest problems are (1) fuel for the outbound and return trip (2) how to land the craft that has humans in it and (3) how to get off the planet again. Mars' atmosphere is too thin for parachutes, and the gravity is too heavy to use conventional chemical thrusters to brake the landing all the way down (which isn't possible anyways due to the mass of the fuel you would have to haul all the way from Earth with those "cryogenic" thrusters).
No one has an answer to this question yet. There may not be one. It's not just engineering, there are basic scientific barriers. This is why SF always invents Warp Drive or some other back door - the constraints imposed by Newton's Third Law and the limitations of chemical propulsion make this whole thing a big pain in the ass. Funny how all these articles never bother to review the basics before launching into all the speculation.
Dude, what the fuck are you talking about? There's no lack of vision. You sound like you have plenty of it.
It's lack of desire to make the tradeoff, pay the cost. How much are you personally willing to pay, to send someone?
Ok, maybe you decided to chip in a few thousand dollars out of your own pocket -- you're willing to eat Ramen for 3 months every year, or give up internet access, or otherise bear that cost at expense to your life style. But now imagine you're not a science-valuing nerd. How much are you willing to pay then?
Answer: as a non-nerd, you're willing to pay about as much as a nerd is willing to pay for $USELESS_GOVERNMENT_PROGRAM. (Fill in that var with something you don't like. Maybe it's the war in Iraq. Maybe it's cancer cure research. Maybe it's tobacco farm subsidies. Surely there's something the government spends money on that you don't feel is worth the expense.)
We have plenty of vision. What we don't have, is consensus on what things are worth. Going to Mars is "cool" but it's not worth the same amount of sacrifice to everyone. And that's a pretty good reason to keep government out of this. Let people pay what they want to pay. Now go write your check and eat your Ramen.

And now our lack of vision as a nation and bureaucratical hassles have pushed the date even beyond that. It's a sad time to be an American. If only we had the drive of the Apollo era.
It's in a bold step of aggressive direction that the 'Prez has led us to this great vision of greatness, to reach Mars sometime in about 15 years! Children not even born yet will be in Junior High when we make it!
Er, not.
This is just political posturing. The lame-duck President gets kudos for being "visionary" without actually doing anything but talking out his arse. NASA gets some (much needed) press, and the Chinese get a message that maybe we aren't completely out of the race to space round II.
But it means nothing, the administration will change, priorities will change LONG before we even get a prototype ANYTHING constructed, and the "vision of the trip" to Mars is half-hearted, even if its proponents aren't.
Personally, this hurts all involved since NASA will end up with ANOTHER black eye of "Well, you didn't get us to Mars, either, did you!" while the real underlying problem, which is that NASA gets about 1/2 of 1% of the budget that the US Military gets.
But most people think of NASA as this huge, labyrinthine gubbmint agency with nearly unlimited dollars. But when you look at it, we spend 200 times as much money killing people as we spend putting anybody in space.
And yet, space projects have had an amazing ROI. For example, the amount of money spent deploying the GPS system is dwarfed by the taxes earned by all the products and services based on the GPS system, notwithstanding its original military-oriented benefits. Research that went into solar panels, rechargeable batteries, materials research, etc. continue to provide incredible economic benefits today, year after year.
It's like somebody upstairs is intentionally shooting us all in the collective foot - just pisses me off to no end.
I have no problem with your religion until you decide it's reason to deprive others of the truth.
Well, it won't happen - because a lot of people, when given this opportunity, would fail in securing their social security; and then when they are in need and without income, what happens? Does the goverment let them starve or offer euthanasia, since no SS funds are available for them?
The successful, healthy, and able people would opt out, since it would benefit them. And the less successful would either die or come to rob your house. (I am exaggerating, of course, but it would greatly increase the social differences, and this would hurt society a lot.)
