NASA: Planetary Exploration, Or Better Coffee
6EQUJ5 writes: "I sighed bitterly when I read the headline at MSNBC_SpaceNews_Front: "NASA voices 2020 vision for Mars" (OK, let's hope I live that long!) Bitterness gave way to sheer comedy when I read the next headline: NASA craft to watch coffee crop. Dan Goldin has the worst sense of priorities if he thinks 20 years is an acceptable time frame for a manned (and/or womanned) Mars mission -- in the meantime NASA picks up odd jobs like watching coffee grow." While these stories make a funny contrast, a) I'm sure there's a lot to learn (and plan) before sending a mission to Mars and b) if NASA's going to test cool new tech, like that solar wing, perhaps giving it a practical earthside purpose is a good idea.
Here is NASA's budget (year 2000 numbers):
$13.6 billion total. The breakdown: $5.5 billion for human space flight, $2.5 billion is for mission support. (I don't know how much of that is indirectly/directly supporting human space flight.) and $5.5 billion for "Space Aeronautics and Technology"
In comparison, the entire National Science Foundation budget is $3.8 billion.
Don't get me wrong, I think space flight is just as cool as the next person, but the return just doesn't justify the expense.
And don't give me some crappy argument about how we will never develop better technology for manned space flight unless we go ahead and just do it *now*. This is pure nonsense. Did we gain anything by going to the moon in 1969 instead of 1999? Nope. Rocket technology would have still advanced just as much over the last 30 years as it did (Think of all the commercal satellites launches). And it would have been a lot cheaper(as a percentage of GDP) if we had gone in 1999 instead of 1969, and we could have brought along a lot better equipment to analyze the moon with than with we did in the early 70's. We would be ahead scientifically, that's for certain.
In general, we can get nearly equivalent science with sophisticated AI unmanned probes as we can with people and for fraction the price.
Which is better: spending several billion a year on a manned Mars mission or spending that same money on researching and building advanced aeronatics spacecraft which will make it much cheaper for to get into space in the first place?
This puts it a much different perspective, doesn't it?
Sorry, it doesn't make much sense to go to Mars just yet. Let's spend our money on the underlying technologies (material sciences, aeronautics, computers) which will make it easier to get us there when we do go. This is the much faster route for space colonization that attempting to got to Mars now.
You have bought into NASA's propaganda machine.
We would have ended up with much cooler stuff if we had invested those enourmous sums of money into other areas. Instead of spending money going to the moon, we could have spent the same money on semiconductor research in the 1960's and 1970's and have jumpstarted the computer industry by 10 years.
Think about it: you would have a computer 64 times faster than the one you have now (Moore's law over 10 years).
"You don't get advances by pumping money into something specific (better microprocessors), you get advances by pumping money into a *goal* (reaching mars)"
This is just isn't true.
IF you have to choose between the two, it's much better to choose technically challenging goals that accomplish sometthing worthwile, than it is to choose goals (like going to Mars) which have little direct benefit.
Take the Human Genome Project. We get something very useful out of it (The human genome map) and we have devoloped several useful technologies along the way (better gene sequencers).
Given that there are countless useful, technically challenging goals we can shoot for, sending people to Mars just for the sheer challenge of it displays a lack of imagination and feel for what are the important scientific and engineering problems we have right now.
Once the ISS is fully populated, we'll know enough about living in space (not to mention have our best launching platform for inter-planetary travel) to be able to establish a colony on the moon. The information gained from this exercise could allow us to easily begin population of Mars, without sending (wo)manned missions that have to return after a few months because they run out of food.
Much better to take the risk of things going wrong on the moon, where anything going wrong won't lose so much time.
In light of this, I can understand the careful planning. But I'm not sure that sending people to Mars is at all a good solution - it is expensive, dangerous (both in the human life and the PR senses) and takes more time.
Developing and sending better remote-controlled and semiautomated equipment would be a better investment, since a) it's cheaper and b) developments in robotics and AI will have added positive side-effects.

Agent Smith apparently never downloaded the Nature Channel. The only thing keeping animals from growing out of control and eating everything in sight is that they just aren't all that good at hunting/reproducing/staying alive, at least as compared to humans. Check out what happens in an area when a local wolf mauls some baby. The wolves are "relocated" elsewhere and the deer population starts exploding until they literally eat everything in sight.
I can guarentee that if some big preadator (like Lions or something) suddenly discovered an easy and effective way to hunt, their population would explode until the prey supply was exausted, then they would starve to death if they don't move on to another area. Humans are the only animals on the planet that actually make a concious effort to not eradicate certain speices some of the time, even when its in our power.
Down that path lies madness. On the other hand, the road to hell is paved with melting snowballs.
I read the internet for the articles.
Never mind all the amazing technology (like, uh, the transistor...maybe you've heard of it...) that you use every day.
The vacuum tube was invented to improve the phone system, and the transistor to replace the unreliable, hot vacuum tube. The initial market was largely military, until Japanese companies like Sony developed the transistor radio. NASA didn't have a whole lot to do with it.
Ooh, a sarcasm detector. Oh, that's a real useful invention.
In a way, a lot of you don't get it. Goldin picked twenty years because in twenty years, people will have forgotten that Goldin made a promise about getting to Mars and we still aren't there yet. I remember when the space station was supposed to be done in ten years; I also remember when the shuttle really was supposed to be economical.
(currently testing something about signatures here)
My mention of war was because war is often the other great instigator of technology. The amount of technical development we've had from the two world wars alone is staggering, simply because the necessity arose.
I would argue that JFK's "goal" of reaching the moon was, in fact, motivated by war. The Cold War was in full swing in the early sixties. NASA was a logical extention of the DOD's missile development programs. The USSR's space program even moreso. When we shot a missile into space with a human aboard, we were demonstrating our technical acumen. We were demonstating that we can go faster, higher, farther...just like with the U2 spy planes. JFK's goal was as much to avoid a "Red Moon" as it was to land a man there.
This leads one to conclude that war (hot or cold) was the primary driving force in technology during that period. Now, we could probably argue that technological developments, while still progressing rapidly in military arenas, are now largely dominated by hardware/software improvements in the private sector. And these are brought about solely by the almighty buck.
That said, going to Mar...or even going back to the Moon, is not going to be a priority in the near future. We don't have to beat the "ruskies" there, and there is no profit in it. The only goal is to fulfill some Star Trek fantasies...and why bother, Hollywood does this for the greater mass of the population...$8 for a movie ticket, or $25 billion for a interplanetary mission?
NASA will continue to be a hard sell. I don't necessarily like the situation, but the conclusions are pretty inescapable.
Heck, watching coffee crops on earth still has extraterrestrial implications - Watching vegetation for subtle changes has applications in watching for any kind of vegetation on a distant planet. It's one of the biggest uses of remote sensing technology today.
But we've all seen what would happen if modified bacteria from a NASA probe ended up back on earth. It's all documented right here. Nothing would happen? I think NOT!

Ah, but Og, rather than send tribespeople, we can throw rocks into the next valley first. Rocks are plentiful, and if there is a an firebreathing invisible-ape, we will hear it go "ouch!" when the rocks hit it. Some same that this is less heroic or exciting than going into the valley ourselves, but it seems very clever.

Mir. If the Russians can manage to keep people alive for months at a time with their inadequate budgets, why can't a Mars ship? I don't doubt there are considerable problems, but I can't see that the life-support issues are the intractable ones.
Assembling things in orbit is an extremely slow and expensive proposition. It's much easier to screw bits together on Earth, where you can just get a technician to hit things with a hammer if they won't fit together :)
Seriously, having to design things to screw together in orbit adds significantly to the cost and complexity - though I suppose that the US, Europe and Russia are spending $60 billion or so to make their mistakes with the ISS.
As soon as the crew launches, you have a single point of failure - what if the shuttle/launch vehicle blows up? Seriously though, it might be a good idea to do that. Why not put the Earth Return Vehicles a couple of hundred kilometres apart, and equip the lander with a couple of cars with enough range to travel to either one? That way, you get the redundancy, and an extra bonus of another base you can use for exploration purposes.
As I understand it, the way the orbital mechanics work out, you can't do much better than a 180-day trip, regardless of the power source, until you can get something that can maintain a continuous acceleration for the whole trip (which would require fusion power or something similarly exotic). Of course, if you can do that, the whole gravity question becomes irrelevant :)
Finally, food? Are you serious? Ever heard of that remarkably complex technology known as "the freezer"? Ever seen the freeze-dried food bushwalkers eat (devised during the Apollo program, if I recall correctly)? Sure, they'll take along a few seeds to see whether the can make them grow in the Mars "soil", but they'll definitely be bringing their food with them using a combination of 19th-century and 1960's technology.
Compared with the difficulty of 100% reliably intercepting ICBM's with another missile, Mars is easy. The greatest problem, in my view, is one you *haven't* touched on, the risk of a solar storm.

This "burn in your minds" ain't new. It's been around here for the last 30 years. Yes, it's cool to state such things. But the fact is, that projects are dropped out, funds are cut and certain politicians even applaud some over-volunteered move from NASA to nail us on Earth.
Mars in 2020? Under the current political mood it would be impossible. Under the current administrative terms NASA rules it is not only impossible but also no less fantastic than a Heinlein's novel.
Today is 14 of May 2001. So we are twenty years from Goldin's dream. Today ISS flies with technologies that Russia created some 20 years ago. USA & Russia flies ships that were projected 30 years ago and have been flying for nearly 20 years. Today most rockets work on ideas that are as old as our fathers. And the large majority of engines preserve the same designs of 30 years ago. Apart from this, we have several interplanetary probes that work on designs projected on the 70s and most of the probes sent to Mars failed.
And today we scrapped nearly all interplanetary projects, except Mars. We also nailed into the coffin tens of projects to modernise and develope the present fleet of ships. The most flagrant, the desmise of the new Space Shuttle design (truly, the US Air Force took patronage of it but they are also not living their best days)
This is the status of our Space Conquer, exactly 40 years after Gagarin... Mars-2020? Give me a break.
I'm not a huge Goldin fan, but you can't blame him for talking about Mars while stuck monitoring coffee. Those priorities are set by Congress, and Congress is very suspicious of any program NASA funds that even slightly resembles preparation for Mars exploration by humans. For one thing, back under Bush, when Dan Quayle headed the Space Council, they delivered an Apollo-style to-Mars-in-20-years program that would have cost half a trillion dollars. Bush had called for the Mars plan, but when he saw the pricetag he didn't know anybody that had their names on it. Congress saw the pricetag and ever since they have believed that NASA is secretly lusting after a twenty-year pork barrel, and they'll try to get it by stealth if Congress doesn't watch carefully.
Meanwhile NASA operational costs are eaten up by a ridiculously expensive launch vehicle and a circular-reasoning space station that, while it has its benefits, doesn't really deliver for the dollar. Science and exploration suffer. NASA is frustrated, but Congress's point of view is that back in 1970 they promised a shuttle that would do A through Z for a dollar, and NASA delivered a shuttle that does A through maybe G for ten dollars.
Short answer: Congress does not trust NASA with money.
The $4B accounting overages in the station program this year are just one more example.
Again, I'm not a Goldin fan, but he does show creativity, as when he persuaded the Italians to maybe come on board the station program as full partners, not just as part of the ESA, by building the US a habitat module, maybe even the CRV. We'll see how that works in terms of actual funding.
For those who aren't aware, there's a nifty Mars explroation proposal called Mars Direct, which would cost a fraction of the NASA proposal -- perhaps $20 to 40 billion. NASA modified it into a $50-100 billion proposal dubbed Mars Semi-Direct. In any case, Congress still thinks a lower figure is a lowball figure and the taxpayer will get screwed in the end.

And before we even get that far, we'd have all the same people making the fuss about genetically modified food and cloning joining forces with all the people making the fuss about NASA wanting to use nuclear power plants in its probes (and thus causing them instead to rely on overly complex solar arrays that probably contributed nontrivially to the recent Mars probe failures) to try to block the development of said bacteria. It's not natural! What if it goes off-course and crashes here on earth?! (Yeah, sure, in reality probably nothing would happen, but try telling that to someone worked up into (Self-)Righteous Indignation with their emotions firmly behind the wheel. They tried explaining that with the nuclear power plant in that outer-solar-system probe a few years back, as chronicled in the first chapter of that e-book about Australian hackers that was mentioned here in Slashdot a while back, and it didn't work then, no reason it would work for bacteria now or any time soon.) How dare we play God, Frankenstein, other classic movie monsters, etc. etc.
People are all starry-eyed about doing all these science fiction things exactly until it seems likely that they could actually become reality. Then all of a sudden all the (tiny) real and (mostly) imaginary risks cause them to scream bloody murder. Gregory Benford had a great column about this sort of thing in F&SF Magazine in September of last year.
In a very real way, one of the greatest obstacles to our space program is not lack of budget, it's all the protesters who will picket Cape Canaveral at the drop of a nuclear isotope. This is the sort of thing that causes NASA to ditch observatory satellites with at least several months of service left in them just to avoid the one in a ka-zillion chance that someone might be hit by it when it comes down otherwise. This is the sort of thing that makes every space probe and satellite we create nowadays more complicated and thus more likely to failure even before it gets into space. This is the sort of thing that will continue to dog us the more advanced our space program gets. Human nature. Human fear. Human stupidity. Is there a cure? I doubt it. Probably not for at least another couple of generations, until most of the fearmongers have died out and the new youth are more open to that sort of thing--unless the fearmongers pass their fear on to their progeny, of course . . .

But people hear the word "nuclear" in almost any context and have their own nuclear meltdowns. To quote Gregory Benford again:
People are scared of it far out of proportion to the actual risks, largely due to reading all those science fiction stories of the previous century in which SF writers wanted to scare people and relied upon the most convenient bogeyman available--nuclear power. We're paying for it now.Look at Chapter One of Underground, which chronicles the launch of the Galileo space probe, despite all the protestors trying to shut it down because there was an infinitessimal chance of something going wrong.
Nobody's saying we should just go ahead damning all risks. But the thing is, the scientists calculate the risks. The odds of Galileo inadvertantly re-entering the atmosphere were 1 in 2 million. The odds of something happening on launch were 1 in 2700. NASA was well aware of the risks, and had done everything it could to minimize them. But the anti-nuclear folks decided not to believe them, and went to court over it.
How infinitessimal a risk is "okay"? Should we not do something because of one in millions or one in thousands odds something might go wrong? Should we stick all our money in a sock under our mattresses because our bank might fail, taking all our livelihood with it? Should we take out mortgages on our houses and live it up, just because we might win the lottery and be able to pay it all back?
Perhaps we should stop using solar energy and look for an alternate power source, because the sun might blow up, destroying our entire planet.
Are these straw men? Perhaps. But then, it seems that most anti-nuclear arguments, like the one against the battery in Galileo, are founded on emotional appeals at their core--the fear of something that only might come to pass, at odds just about as infinitessimal as our bank failing or the lottery paying off, or, to use the old cliche, as being struck by lightning.
Heck, look at Three Mile Island and Chernobyl, the worst nuclear accidents of all time. I mean, really look at them. Here's another quote from that first Benford article upthread:
People are against nuclear power because they're scared of it. And in many cases, for no real reason other than what might happen.--

Think there's anything in the world without risk?
Here are some excerpts from A Scientist's Notebook: Risk and Realities by Gregory Benford, Fantasy & Science Fiction, Sep 2000, Vol. 99 Issue 3, p112, 12p., retrieved from EBSCOhost via my public library's website. (Much as I'd like to, I can't paste the whole thing without stepping far outside the limits of Fair Use, so to obtain it with all context intact, go to your local library or equivalent website.)
. .Risk is always present. We can confine it to within acceptible levels and move forward, or we can try to make everything completely "safe" and stay frozen right where we are--because no matter what, someone is going to object to any attempt to introduce bold new techniques or technologies (ion or nuclear propulsion, anyone?) as too unsafe to try out, even under carefully restricted study and implementation. We can't just stagnate, or we'll never get humanity off this rock and safely ensconced on other planets before someone finally goes nuts and pushes The Button.

I would rather spend less of my tax money on unmanned probes. I think I will get far more "spinoff" per dollar that way, without sending some poor people into space to deteriorate physically at best and die at worst.
I think we'll get FAR more cost benefit from developing smart machines to explore Mars for us. We can turn right around and use these smart machines here, WITHOUT the expense of boosting a multi-year human habitat and life support all the way to Mars and back.
Silicon survives in space better than people, after all. The only benefit of sending people instead of a probe is so that we can put footprints in Marsdirt.
Our trips to Mars should serve as the beginning to the eventual human expansion into space, and not some cheap theatrical stunt. They should be accomplished in a considered and sustainable manner.
But what will that do to FOX, and their cadre of "ex-spurts" and investigative reporters? If it is done well, in a sustainable manner, how can FOX run, "Did We Really Go To Mars" in 2051?

"Outlook not so good." That magic 8-ball knows everything! I'll ask about Exchange Server next.
I think it was Popular Mechanics last fall that had an article on the debillitating effects of prolonged null-G living. They talked about rotating craft, but also about exercise machines that could create their own gravity. For example, a not-quite-stationary bicycle. Picture a vertical centrifuge, with a seat, pedals and handlebars in place of the "pod" that the person sits in. (Turn the centrifuge shown in so many space movies on its side.) Pedalling the "bike" causes the centrifuge to rotate, providing "gravity" to the person on the "bike." Possibly cheaper than a controlled rotation of the entire craft.

Risks can be managed. The risks from nuclear thermal generator power plants in satellites are vanishingly TRIVIAL compared to, say, getting into your bathtub with wet feet.

Twenty years? Dear God, the American rocketry program went from zero to the moon in eight years.
The problem has nothing to do with technology, and everything to do with motivation. The American public is not sufficiently well-versed in history to realize that all exploratory endeavors like this pay back many times their cost. I'm making a purely economic argument...one which I believe is trivial compared to the sociological one. Humans are defined by the frontiers they conquer. Our lack of a frontier spirit shows up on the front page of every newspaper on Earth. Mars (and space exploration in general) provides an excellent goal. Why are we wasting 20 years to get to it? I've seen mission plans that cost 1/10 what NASA plans to spend, which allow us to set foot on Mars less than seven years from TODAY. Unfortunately, NASA is more concerned about preserving their monopoly on American heavy-lift rockets (a task for which the Space Shuttle is staggeringly ill-suited) and building Battlestar Galactica (er, I mean the ISS) to actually pick an EFFICIENT plan to go to Mars.
I want to go so bad I can taste it, but it looks like NASA is doing everything possible to thwart the dream...
Why yes, I AM a rocket scientist!
Like what, smart guy? If not for the Cold War, the money would have probably gone into some useless black hole like welfare (we called it the Great Society back then) or educational reform...and gotten exactly nothing back from it.
The tax revenues from the communications satellite industry alone have more than paid NASA's funding. Never mind all the amazing technology (like, uh, the transistor...maybe you've heard of it...) that you use every day.
Why yes, I AM a rocket scientist!
Considering the advances in life sciences and engineering we've made in the twenty (!!!) years since we went to another celestial body, and considering that getting out of Earth's gravity well puts you about half way to anyplace in the solar system (from a logistics standpoint), I'd say that an eight year plan to get to Mars is not overly ambitious. Twenty MORE years is just lazy.
Why yes, I AM a rocket scientist!
Or think about Apollo 1. Gus Grissom, one of the astronauts who died in the fire on the launch pad, stated explicitly that the exploration of space is worth the sacrifice of human life. Every astronaut who ever strapped on a rocket knew the risks involved. They had huge numbers of brilliant people working beyond the limit of endurance to minimize those risks, but the risks were still there. The Challenger astronauts were no different...they knew that their chosen profession was risky, yet they stepped up to the line and took their chances. Any astronaut who thinks that space travel is "safe" is incompetent and not fit for the job.

As far as your argument about pollution, I must infer that you haven't the faintest idea how a nuclear thermal generator works. If you did, you wouldn't be drawing these ludicrous parallels between NTGs and fission piles. They're about as much in common with each other as a yo-yo has with a semi truck.
Here's a bit about NTGs. Machines with zero moving parts don't often fail.

Besides, no one is forcing people to work on this specific plantation.
Uh, not to mention the piles upon piles of research data. We have the Apollo program to thank for all sorts of advancements.
NASA is an arm of the US federal government. It operates on a 15 to 18 year cycle of high employment because otherwise its employees would start to acquire pension rights. Hence assuming that its operations will move at a faster rate is unrealistic. I think Goldin is being much more realistic than anyone is giving him credit for.
So long and thanks for all the fish . . . !!!
I wouldn't doubt that it could take 20 years for a manned Mars flight. If you knoe the history of the moon shots you know that it's a damn miracle that they ever worked at all. Just shove some guys into a tin can and blast them off into space! Yes, it was super cool and it did turn out great. But they technology that was used really wasn't up to the task. It was they men and women who were behind the metal and machines that made it possible. And I honestly don't know if we have any people like that around anymore. A good reason for this can be seen in this article published in the May issue of ComputerUser.

How true. The conditions on Mars are so harsh that it will make an outstanding location for a penal colony. Mars will be our prison!
Ha! You never know... Maybe it will start out that way, then go the route of Australia. Actually, that would be kind of cool if the penalty for violating the DMCA was deportation to Mars... Copyright violation, here I come.
Could be so, it could be that Mars is 20 years away just like AI and (useful) fusion have been 20 years away for the past 30 years. On the other hand, it does sound like he's saying, "we'll be there in 10 years if you fund us more, 20 years if we keep up the current pace".
If he's not lying through his teeth, that's good enough for me.
I also find 6EQUJ5's whining about the 20-year plan to be misleading. Again quoting Goldin:In other words, if we put the same kind of effort and sacrifice into this that we did with the Apollo program, we'll be there in 10 years. Otherwise, 20 years. That's comparable to the timeline for the Apollo program, and it seems reasonable to me.

I don't think it's that simple. The Europeans moving to America found a surrounding there that was able to support them easily. There were plants and animals and water and breathable air. Yes, it still was hard work, but at least they didn't have to bring everything with them for hundreds of years.
I am not all that convinced that Mars is such a worthwile goal. Yes, it is a goal in itself. But apart from that, I think the benefits of people settling on Mars are exaggerated.
Even the part about growing semiconductor crystals in space and stuff proved quite useless (or at least not economically interesting), and that was a concrete plan. But for Mars, I haven't seen any ideas like that.

Honestly though, they should take as much time preparing to get it right. I would rather see them wanting to wait 19 more years at the cost of a couple billion tax payer dollars, then see them spend a couple billion per year in failed missions going there. If all else fails, they could always fake pictures of lannding on Mars (har har) or explore another planet. Whats the big fascination with Mars anyways, there are so many others involved. Are they leaking out something they don't want the public to know?
I've never heard any major stories surrounding any trips to other planets. Come to think about it, aside from Mars and the Moon, I've never even heard of any trips to places like Jupiter, Saturn, Neptune, etc. Do they know something they don't want others to know?
Want Root?
If there would have been any actual benefit, be it from exploiting the resources, the technological advances made, or just sheer happiness of the people, we wouldn't have stopped after less than a dozens trips to the Moon, all about three decades ago.
I cannot fathom one benefit from sending people to Mars. Sure, it would trigger some new technologies - but that's not Mars specific. After all, technology has advanced rapidly even after we stopped going to the moon, not to mention its progress the thousands of years before Kennedy's reactions on Gagarins first trip into space.
What did the manned trips to the Moon bring us that we wouldn't have had without them? Neither velcro nor teflon were mined on the Moon. And the handful of rocks that were brought back could have been brought back by unmanned flights as well.

Given Three Miles Island, Chernobyl, Sheffield and a handful of smaller incidents, it's clear that either we apparently don't have the proper procedures, standards or training, or that your claim is incorrect.
Nuclear reactors, when handled properly, aren't any more dangerous than any other large, complicated thing that gets hot.
It's not the temperature that makes nuclear reactors dangerous. It's the thing that causes the high temperatures that's dangerous.

Eh, yeah, right. Care to calculate how many rockets are needed before the moon has a base advanced enough to create earth bound satellites solely from the resources found on the moon? Could you compare that, taking into account that a rocket needed to shoot something to the moon is bigger and heavier than one to shoot a satellite into orbit, to the number of launches needed for satellites? And, while you are at it, compare the number of satellite launches to the number of launches needed to sustain the moonbase?

I dont get it. With all the research going on surrounding hardy micro organisms that can survive extreme temperatures, why are they not looking into changing the climate of another neighbour of ours: Venus?
Is it not unreasonable to believe that we could develop a bacteria that can survive extreme temperatures and pressures? They already exist on this planet, so who is not to say they cannot (with a few modifications) survive there?

You can't rotate quickly or everyone will get motion sickness. Studies I've heard of indicate a rule of thumb is one revolution per minute maximum.
Do the math. To provide 1 G of rotational accelleration at 1 RPM , you have to have a radius of about 900 meters.
w = (1 / 60) * 2 * 3.1416 = 0.105 radians / second
a = w^2 * r
1 G = 9.8 meters / second^2
9.8 = 0.105^2 * r
r = 894 meters
If we do go we will need:
-
some form of artificial gravity. I don't see the big deal here - just spin the damn space craft. I've heard some comments that there are problems controling two body systems in a stable way, but there must be some way around it (rigidity, three-body systems, active feedback...?). All this endless talk about overcoming weightlessness (sp?) is stupid when such an obvious solution is at hand.
- Lots of redundency. We can't, for example rely on having a single ship (fueled by one of these proposed fuel `factories') at the other end ready to come back. It is too large a single point of failure. We'll need to send at least two of everything and three of some things.
- Size. The space craft will need to be large enough that the crew don't go mad and actually are comfortable. No spacecraft to date has been comfortable. NASA's approach seems to be: design something just big enough that the crew don't rip each others bodies apart inside a month and call it a success. It all seems motivated by wanting to fit the whole craft on a single, Saturn 5 style, launcher. Why? Surely a ship can be assembled in earth orbit.
- Cost. Its going to be expensive. It'll cost at least $150 bn and probably more like $1 trillion. All this stuff about Mars on a shoe string is balls. It might be possible, but it won't be safe and nothing good would come of it. The crew would be miserable and in constant danger. Mars rather than a tax cut anyone?
- Propulsion. It'll need to be done as quickly as possible, which means propulsion. This in turn means Nuclear (either directly or more likely powering a plasma drive or something). Nuclear means hard time winning over the public (even though it is so obviously the only choice and I am not generally a supporter of nuclear fission)
None of this is in place. No propulsion system, no power systems, no space suits, no large ships (could we just fit out the ISS and actually make it useful?), no reliable food source (what if crops fail?) and heres the crux of it: NO MONEY. It will happen when there is cheaper access to low earth orbit and all these technologies are more mature. Perhaps I'm too young to remember Apollo, but that was a series of (remarkably lucky and I mean no disrespect to the people who worked on making it as safe as it was) week long outings. This is an eighteen month voyage. It is like assuming you can stay under water for two hours just because you managed to hold your breath for two minutes.Okay, I agree that there are a lot of agricultural applications for this technology. But a couple of things just don't jive when we are talking about coffee. The article states:
First of all, the coffee cherries are not picked all at once, which is why coffee havesting is still done by hand. They ripen at different times and only the ripe ones are picked. Whether to pick or to leave a particular cherry on the tree is a human judgement call that can not be done by machine.
The only way I could see this technology being applied is to determine the optimal time to strip-harvest the entire plantation by machine. It might actually save labour costs to sort the ripe beans from the unripe ones after they are harvested. But isn't this a terrible waste of otherwise good coffee beens, which, left on the tree longer, would produce good beans? Premature beans that get picked have to be composted to be of any use at all. Anyway, I think that such labour savings would only be significant in the US (i.e., Hawaii). In the countries where most of the worlds coffee is grown, stripping the unripe cherries from the trees would be more costly (through reduced yield) than by reducing the already cheap labour.
From a flavour point of view, all this is moot anyway, since most of the worlds good coffee is a) improperly roasted, b) blended with inferior robusta beans and/or c) stale by the time it reaches the consumer. Never mind that most people don't even brew it properly.
That's why I roast my own arabicas at home.

Agent Smith, from Matrix, said once:

Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment. But you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed and the only way you can survive is to spread to another area.There is another organism on this planet that follows the same pattern. Do you know what it is?
A virus.
Human beings are a disease, a cancer of this planet. You are a plague. And we are... the cure."

Dan Goldin has the worst sense of priorities if he thinks 20 years is an acceptable time frame for a manned (and/or womanned) Mars mission.
What's wrong with it? I think it's an admirable goal. NASA's technically there already in terms of technology...they did plenty of research and development in the 70's, figuring out how to launch humans with the power of a nuclear rocket to Mars. There is only one problem: round trip is 1 year, 3 months time.
What NASA has to do is figure out how to extend the physical and mental stress environments in order to accompany humans through space for that long period of time. Easiest (conceptual) solution: create some means of artificial gravity (I said a conceptual solution, not realistical). Well, either that, or make a faster rocket...
They could do it in ten years...heck, I'm sure they could "do" it in five years, but for reasons of PR and government funding, they need the other 15 for research, development, and PR work.

I don't buy that rubbish about KDE developers advancing faster because of the coffee, though.

The real reason is that GNOME's Mexican element is encouraging heavy indulgence in tequila, marijuana, and siestas.

I like to watch.
I want my money back. We WILL go to Mars, but NASA's not the way to get there. One day, when technology has advanced sufficiently, then we will see private enterprise take over the push into space. The reason that's not happening now is that it's just not worth it. There is no return we can get from NASA that's worth the money that's put in. If there were, companies would be rushing head first to do it themselves.
The only "intuitive" interface is the nipple. After that, it's all learned.

If this is ever tried, it either has to be a faster trip (which would require something other than chemical rockets) or a big spacecraft that rotates to provide gravity. Nuclear propulsion would work, but the political problems are tough.
We would have ended up with much cooler stuff if we had invested those enourmous sums of money into other areas. Instead of spending money going to the moon, we could have spent the same money on semiconductor research in the 1960's and 1970's and have jumpstarted the computer industry by 10 years.
You seem to be assuming two things:
1. There are insuffcient resources to engage in both space exploration and semiconductor research with any degree of success.
2. That desireable avenues of research and exploration are trivial to identify and commit to.
Re 1: History suggests that this is not true. Generally, resource shortages have always been due more to bad resource management than a true scarcity of resources. We could conceivably have both "successful" space exploration and "successful" semiconducto research - at the same time.
Re 2: Isn't it a little anachronistic to demand that your predecessors have the same desires and goals as yourself? Just because you would have chosen semiconductor research over space exploration in the 60s and 70s - if you knew then what you know now - this doesn't mean they should have made the same choice. In fact, it looks like everybody - the goverment, the populace, the scientists, &c. - wanted space exploration. So that's the direction they went in.
Your argument is like saying the ancient Egyptians should have researched Existentialism instead of Pyramids, or that the ancient Greeks should have come up with a polio vaccine instead of the Socratic Method.
Your criteria for evaluating the prior achievements of a society are underspecified.
Any sufficiently well-organized community is indistinguishable from Government.
I agree with the first part of your statement - it's not so much what you get when you reach your goal (Mars), it's the knowledge you gained when you look back at everything you learned on the way there.

Silly examples aside, I was just trying to illustrate the short-sightedness of assuming we have everything we need right here, and have no reason to go to the next valley. The same pressures that drove human migration across this planet -- population pressure, economic problems, war, get-rich-quick dreams, and, yes, a compelling urge to Be Somewhere Else -- will eventualy drive our migration into space. The universe belongs to us and anyone else who lives there. As soon as the technology is economically viable, we will Be Somewhere Else.

Seriously, what is up with US coffee?
Starbucks is tasteless slop, and US instant is the worst in the world - it's just about undrinkable. Meanwhile, smaller coffee shops that were the last bastions of good coffee shut down all the time, unable to compete against the economies of scale of the larger coffee corporations.
I don't see this happening much in Europe. The big multinational coffee corporations are present doing their dirty work but they have never achieved the same level of mindshare penetration, and consequently there are fewer outlets and they are less busy. The traditional small coffee shop or cafe still has a chance in Europe, and as well you can even buy drinkable (i.e. it doesn't feel like Draino trickling down your throat) and decently caffeinated instant coffee in the supermarket.
I am firmly of the belief that this is the primary reason why KDE (a primarily European-developed environment) is advancing faster than GNOME (a primarily American-developed environment). It is simple. KDE developers get better coffee!
So don't laugh about NASA funding satellites to watch coffee grow - it is vital to the development of Free Software in the US!
Didn't Michael already post the Mars 2020 article here?

As far as an earthside use, I can't wait for my own Mars rover PIM! It'll follow me around, make me coffee, and subvert large rocks in the terrain of my driveway...
It would probably be a wise move to attempt colonization of the Moon before colonization of Mars. The moon would serve as a shakedown field test for technology and techniques. If something goes wrong, it's a lot closer back to Earth.
The key to major investment in the Mars program is potential profit. Mars is an untapped planet of ore, minerals, and *potentially* fossil fuels. While Congress might hesitate to fund a Mars mission for humanity's sake, they'd be happy to do it for Diamond's/Gold's/Oil's sake.
And while the concept of stripmining Mars may seem unpleasant, it's quite necessary, and is the only way we'll ever see real colonization attempts. (Such mining would be severely limited, anyhow, due to purely geographic reasons.) Just as the New World provided land and resource to 16th-century Europe, so would a new world to 21st-century America.
I imagine that such a massive endeavor is also going to require privatization. We've had the technology and resources to set foot on Mars for years. It's been a cf of silly alternate programs and disasters that have been the restraint. After the Martian rover wowed the American psyche, NASA should have intensified its efforts to get a manned expedition underway. A simple American flag on the surface would have been the catalyst for colonization.
Dennis Tito has probably done more for the space program than he ever could have dreamed. I suspect that cash-strapped Russia will continue it's space tourism sideline. Eventually, it's going to allow a private commercial enterprise (no pun intended) to begin space flight and exploration. American industry will eagerly invest in such programs, (think of the profits and PR) pressuring the American government to allow similar commercial exploration (under the auspices of NASA, who would serve as an administrative body. NASA would undoubtedly continue it's scientific work as well.)
In his upcoming report of massive military overhaul, Secretary Rumsfeld also seems to be casting an eye towards space for military endeavour. (Beyond the missile defense shield.) Not to sound too Trekker, but Starfleet may be closer than we think.

Formerly a senior engineer at Lockheed Martin, Robert Zubrin is the founder of Pioneer Astronautics, a space- exploration research and development firm. Currently chairman of the executive committee of the National Space Society, Dr. Zubrin is the author of more than one hundred articles on space propulsion and exploration, and is widely regarded as the nation's leading theorist of Mars travel.
Another interview and more info on Dr. Zubrin is here.

There's no point in being grown up if you can't be childish sometimes. -- Dr. Who
I was fortunate enough to attend a presentation by Robert Zubrin when he was on my campus about 3 months ago. He provides a compelling argument for a direct-to-Mars project, utilizing technology which currently exists. We could be on Mars in under 10 years. Specs are located here. Zubrin, a succesful author, is also one of the leading supporters of the Mars Society. The most fascinating aspect of their proposal, is that they want to use "private" funding (ie not governmental funds). I really don't know of a cooler open source project. This could be the next SETI@Home.

"Sanity is calming, but madness is more interesting."
I guess what you are kind of saying is "We got a lot of stuff out of the exploration of space and the shot to the moon because so many different technologies were advanced. But now that we've done that, we are really only extending the capabilities, and not therefore going to produce those neat spin-offs like astronaut ice cream and space blankets."
I kind of agree. What will we accomplish by landing there? It isn't like in the movies, when we find all these killer bug-like creatures or are enlightened and attuned with the unverse by meeting up with some wispy gay Martian guy. It will be like the Moon Landing, but with better audio/video, and much more coverage. Or no coverage; hard to tell since the timelines are so long.
On the other hand, why not go to the moon? We sure spend our money on worse things, and relatively speaking, this would be a somewhat noble human conquest, turning all our heads skyward. NASA represents a lot of what is Noble about being an American, and a human being, too.
The real answer, of course, is that we Are in our birthplace, and our graveyard, and it's our job to take care of everything in between. If you want to talk priorities, think of NASA's Mission to Planet Earth. Now there's a good spin-off, IMO.
One more thing: I got the pleasure to hear Dan Goldin talk at a company meeting. Very dynamic fellow, and compelling as well. I'm sure he's from my hometown area New York! I can't imagine a neater job than to be steering the largest non-military space program in the world, albeit after the Challenger disaster. (Well, except for that last part, the job would be cool.)

Historically, modern science has always been funded by someone else. In the 16th and 17th centuries, monarchs and other nobles funded science because they felt it was a sign that they were enlightened. They also hoped to reap any technological benefits that developed.
In the 18th and 19th centuries, science become the realm of the universities, who funded its members to research purely for the sake of research. Academic reputation had been established by societies such as the Royal Society in England and the Academie des Sciences in France. Scientists were pressured to generate research on the basis that their rewards would be academic fame.
In our time, science funding has returned to the realm of the state. Universities do fund the sciences, but to get significant funding you must petition the state. NASA is an extreme example. NASA must always petition the state for funds because no one else can put up that kind of money. All the academic institutions in the country would not be able to foot NASA's bill (and still function and universities). Therefore, because NASA is funded by the state, it is expected to return something to the state. After all, the state's money is the people's money right?
Personally I operate on the belief that my tax dollars (which I grudgingly pay every year) is not my money. It was my money, but as soon as I wrote a check to the "United State Treasury," I gave that money up. In effect, I gave the money to the government, which I have recognized as my state. It is up to the state to decide where the money should be spent. Now I can influence my congressman and my senators and the president to spend the money in a way in which I see fit, but that is an artifice of the system of government in which we live in. (Notice I am making a distinct difference in what a state is and what a government is.) If for some reason we lived in Soviet Russia in the 1960's, we would have no say in the government on how our state spends its funds (on space research or nuclear weapons).
Now we can get into an argument about governments and states and things like Jean-Jacques Roussea's Fundamental Rights and Freedoms and the interaction between the state and its people. My point is that Congress decides how much money NASA gets. Congress happens to expect a "return for its payment." This attitude is a result of our values as a society. As a scientist, I would rather see a society in where science funding can be given without any expectation of a return. Pure science is just as important to me as any technology for the citizenry.
and therefore good for mars. despite all the advancements in communications, weather, gps, computers, superconductors, metallurgy, and many other daily household conveniences that we take for granted that are directly attributable to NASA's research and space missions, the public in general, and the conservatives in specific don't believe the investment is worth it. projects like the coffee watching have the dual benefit of showing the commercial value of space to those with no future vision as well as providing revenue for NASA. given the present administration, it will most likely become very important for NASA to become more and more self sufficient in the near future if they are to survive at all.
I'm all for a mission to Mars in 20 years, but I hope it doesn't take much longer to find a good reason to do it.
While it is generally agreed that Columbus was not the first European to discover America, he was the first to generate any kind of commercial interest to be there. Just 100 years after that, serious settlement began. The same thing could happen on Mars, perhaps within a similar timeframe. You might think that's an outrageous, not to mention expensive proposition, but I'm sure that Europe had the same sentiment just 500 years ago.

You fools! You let a glib story by Microsoft-NBC determine your perspective towards NASA's development of remote sensing drones, all because the testing phase involves the agriculture of coffee (which someone aparently finds trivial). As punishment, you will spend this afternoon reading about NASA's efforts to develop and deploy useful technologies for Earth observation. Fire up your search engine, and feed it terms like "mission to planet Earth" and "Destination:Earth" to find out how NASA is doing neat stuff that is of real value.
"That's one small sip for man, one giant leap for making better coffee" oops
Well, we have gotten some cool stuff from NASA, other then Tang, of course. But a lot of the stuff they have come up with has been inspired by sci-fi writers to begin with.
Regardless, I'd much rather see more "space-tourists" like Dennis Tito, as a way to help defray the costs of ISS, and as a way to increase awareness in the space program then all this Mickey Mouse shit they're doing now.
As for this 20 year wait for a trip to Mars, IMAO, that's way too damn long. But part of it (only part) might be waiting for a proper orbital conjunction so the astronauts have to spend as little time as possible in between the two planets. I mean, it's going to take a while to get there anyway, so why not minimize it?

...of a number of factors, its atmosphere being the least important. Atmospheric engineering is a doddle compared with imparting angular momentum or radiation shielding.
Venus rotates extremely slowly (and retrograde, meaning opposite to the direction Earth does), such that its day is 243 Earth days long; more than one Venusian year. This would obviously have to be fixed before anything else. In comparison, Mars has an orbital period of just over 24 hours, and would probably require no adjustment.
Venus (and Mars) have no magnetic field to speak of. This means that there is no shield from the Sun's radiation, and is a serious impediment to successful terraforming that has not been adequately dealt with in any proposal I have seen.
"It would probably be a wise move to attempt colonization of the Moon before colonization of Mars. The moon would serve as a shakedown field test for technology and techniques. If something goes wrong, it's a lot closer back to Earth."
We'll probably go back to the Moon sooner rather than later. NASA has a 'secret' wish list called the 'Decadal Plan', which examines what they would like to do in the decade following the completion of the International Space Station in 2006-07. Rumour has it that they are looking at 100-day missions outside lower Earth orbit, either extended stays of 2-3 months on the Moon, or (even cooler), missions outside Earth orbit entirely to passing asteroids. The ISS would serve as an assembly and staging post for such missions. I wish I had a link for this, but it han't been leaked in its entirety yet. Any obliging NASA employees out there?
"The key to major investment in the Mars program is potential profit. Mars is an untapped planet of ore, minerals, and *potentially* fossil fuels."
Leaving aside the extremely dubious possibility of fossil fuels, it is unlikely that bulk materials mined from Mars will ever become a commodity here on Earth. You'd have to boost them out of Mars' gravity well and on a trajectory back to Earth. We mine mineral ores here on Earth by the millions of kilograms, so unless we develop antigravity anytime soon, it's unlikely to be economically feasible.
Far more likely is the exploitation of mineral resources in Earth-crossing asteroids. A lot of them are essentially billion-ton lumps of high-grade metals. We could install big ion drives or other propulsion sources on their surfaces and slowly coax them over a period of years into a (high enough for public-opinion comfort) orbit around Earth. It would then be simple to use Earth's gravity well to deliver the mined materials direct to Earth's surface.
Even this is unlikely to ever happen. We just aren't that short of raw materials here at home, and recycling is likely to be far more economical for the forseeable future.
Most NASA technology has been great in terms of spinoffs we can use here on earth. You probably use them all the time

- Watching crops (as we see here) to improve yields, etc.
- Watch crops, for DEA-type purposes
- Monitor large areas of forests for fires
- Loiter over an enemy target
- Provide radio relay
Just to name a few.Plus, I am a fan of really, really good coffee.
My guess is that NASA or any other government space agency will not manage to do manned missions much further from our near interplanetary space. Return to the moon, sure, go to Mars, possibly, much further out than that? Not likely. Or, they will accomplish even more than that, but where will the money come from? The tax payers? Those money will have to be used for other things than just space exploration. I've said it before but I still think that space belongs to those who can make money from it. Space tourism, mining, exploration and research, most of that will be done by private enterprises, companies, universities, etc. etc..

Crop Watching has been on of the benefits of satellite and high altitiude photography. Photographing fields in different spectrums can show alot of information.

I tend to go for a more middle-of-the road approach, as in "leverage *all* forms of space research, whether far from or close to home, for the direct benefit of all on Earth." Unfortunately, this requires more of the average citizen than is commonly found: the ability and interest in taking the time to *really* research what's actually happening in space tech, *really* research what's actually lacking in our societies as a whole, and merge the two into concrete objectives.
I'm as guilty of this as the next Joe, but it's generally a true statement the most people who are heavily involved in hard science and research aren't heavily involved in "human matters." Kind of a paradox, I suppose.
I'd appreciate comments on this (seeming) issue.

Earth is our birthplace, not our prison. The purpose of humanity, if we can be said to have a purpose, is to disperse life throughout the galaxy.
That's nearly a direct quote from Octavia Butler's Parable of the Sower, a sci-fi story about a girl who fled her gated community when it was attacked by gangs and angry mobs. The dream that kept her going specifically was for humans to "take root among the stars."
I whine about "20 years" because NOBODY can be held accountable for that long if things go wrong. Even some murderers are released in less time. What if I promised I'll build you a huge, elegant mansion to live in.. but I won't be around when it's finished- how convenient! No earth can ever be broken on big, risky projects if people aren't held accountable. With a 5 or 10 year project, at least you'll have someone to blame when bad luck, incompetence, and cowardice all come together and the mission fails.
Helping coffee growers max out their yearly profits is absolutely ridiculous. It's a nice, safe mission, isn't it? I'm sure the iron men of the old NASA would be very proud. (lol)

Is there life on mars? I dont think our government knows for sure and the reason they want to wait 20 years for a manned mission is because if there IS life on mars i dont think they'd want a manned crew to see it. Heres what i think, i think after the so called rock with life in it from mars, and the water markings on mars and all of the clues and hints that life on mars is possible, our government is playing it safe. 20 years is silly, we could have went to mars 10 years ago if we tried Fact is, our missions to mars always seem to go wrong and these are with robots, we arent sure if theres life on mars or not so exposing humans to it could be dangerous, this is why we dont go. Sounds silly i know, but it does make sense. While everyone will say theres no life on mars, we cant prove that unless we drill into mar's surface, and its funny that our next probe to go on mars is going to do just that, drill into the surface.
