When I think of how much deuterium the Chinese are going to extract from the water going through that gigantic dam they're building, it makes me very hopeful about the future of fusion research. Whether the anti-nuclear activists like it or not, they won't be able to bully the Chinese government with lawsuits and the like. I honestly believe that clean fusion power will eventually become available, just not on the timetable the science fiction writers imagined.
Then again, "2001" may depict our space activities in 2100 AD more accurately than it did the year gone by.
I am always hopeful.
I have to qualify my often hostile comments about environmentalism. I support clean air and water legislation, and favor harsh punishments for corporate executives and their underlings who seek to illegally dispose of their companies' hazardous waste. I guess for the reasons you've just stated, I have felt alienated from the mainstream environmental movement for a while.
With NASA's current plans, Mars will have to wait at least several more decades before any Americans set foot there. That's not to say that other nations couldn't get there first. It's just that NASA's blueprint for the future seems to be to pour money into more space stations at the Lagrangian points after the ISS is completed. I know that what NASA wants (ideally) is a spaceport for orbital construction, but my concern is that the (no pun intended) astronomical costs of endless redesigns and delays will leave no money for anything but a few nice-looking but underfunded and basically useless space stations. Well, not totally useless. Maybe they'll be able to do on-orbit servicing of the new space telescope.
Hopefully "The Case For Mars" has been translated into Mandarin Chinese.
I should know. I always pick through the building at the local dump where people leave things they don't want, but are still in decent condition. I've found several perfectly good bookcases that way!
They don't match, but I'm a man...so those things don't matter to me, anyway. My wife says that I sometimes leave the landfill with more trash than I entered with. LOL
Holy "Empire Strikes Back"!
A City In The Clouds, on Venus?
I love that idea! You know, I'd bet you could extract enough hydrogen from the sulfuric acid in the atmosphere to create water for dozens of people!
I also wouldn't mind seeing a water-rich, near-Earth asteroid moved into orbit around Venus. It would test our abilities to move a potential Doomsday asteroid, and provide a nice worldlet to colonize as well. The gravity well of Venus might not provide too much of an obstacle to mine some of the gases from the atmosphere with a spacecraft designed to skim the uppermost layers.
Shaun, I don't believe that it would be difficult to establish a balance of trade between Martians and denizens of the outer solar system. Colonists on worlds near Saturn, Uranus, and Neptune could (hypothetically, anyway) export Helium-3 and volatile-rich comets (for terraforming) to Mars.
Maybe the Martians could build an empire of their own by establishing settlements out there, to supply a need for the outer solar system's virtually unlimited natural resources.
Oh! I was so mad at NovaMarsollia's posts that I didn't read the stuff that followed.
Thanks, Adrian...good riddance to bad rubbish. (Of course, my question about the old saying is, what constitutes "good" rubbish? :lol)
I haven't been here in awhile. Good to see the usual crew of thoughtful brainiacs are still here.
Ad Ares!
My most compelling reason to support the colonization of Mars is that people like NovaMarsollia seem to have an almost religious belief in the unworthiness of human civilization to exist on Mars...or anywhere else. "Apologize" to the non-human living things which perish to sustain your own life? You're nuts.
Repeat after me. Life on Mars, IF IT EXISTS, is simply life. Like the bacteria in your feces, or the fleas that bite you. Mars is not Heaven, nor is it the Garden Of Eden. It is simply a place.
I want to see humanity establish a new branch of civilization there, like my ancestors who landed in New England centuries ago from Germany and Britain. The motto of my home state of Connecticut is, "Qui Transtulit Sustinet"...That Which Is Transplanted, Is Sustained.
My "dirty American footprints", indeed.
Here's a news flash, NovaMarsollia. The "techno-imperialists" who share my dream will someday leave you and your Luddite confederates behind. Then you'll be free to force the Terrans to adopt your "Eco-friendly" proposals at gunpoint. It's what you people secretly want, anyway...even if you don't have the guts to say it.
I should have clarified my statement about the 'billions' of beneficiaries of terraformation. Actually, I really was referring to the future unborn generations of Martian citizens. Their 'Green Mars' would have a carrying capacity of billions, instead of the millions which 'Red Mars' could support.
My apologies for the mild sarcasm. I just believe that the scientific value gleaned from studying an eternally Red Mars pales in comparison to the benefits which could be enjoyed by the billions of citizens a partially terraformed world could support.
Geology IS important. But to me, studying rocks is only a means to an end. At the point which preserving Martian geological strata becomes more important than improving economic opportunity for the ordinary citizens of Mars, it really does become "playing with rocks".

But I have to agree with the preceding poster. Any idea of settling the outer solar system is probably a long way off.
For settling planetary systems beyond Jupiter, I actually prefer O'Neill-type rotating habitat cylinders whose superstructures are made mostly out of water ice. At Saturn and beyond, cryogenically frozen H2O behaves like industrial steel...and it's incredibly abundant. Placing the colonies at Trojan points (co-orbital with major moons like Triton or Oberon, but 60 degrees ahead or behind in their orbital path) would allow mining outposts using mass drivers to regularly transport millions of tons of natural resources from the icy moons to habitat cylinders. Hybrid fission-fusion reactors which have ALREADY been designed could provide enough electricity to support billions in a level of comfort that would be envied by most in the world today.
I love the idea of settling Mars. But the truth is, I like the idea of settling the Uranian system much more. As little as Terrans might care about what happens on Mars, they'd probably care even less about Uranus. 'Ariel Co-orbital Cylinder One' sounds nice to me.
I agree. I abhor the wanton destruction of the natural environment, or anything else. But a balance must be struck between the needs of an advanced technological civilization, and the needs of the ecosystem which sustains its denizens. I simply disagree with the more extremist elements of the environmental movement, who seem to value plants and animals more highly than people. The fascist undertones, combined with the misanthropic sentiments voiced by some of its rank and file, are big turn-offs to me.
Hey, no joke...I am a neo-pagan myself. No offense taken. Polytheists are no different from monotheists (or atheists, for that matter) in the sense that they encompass the entire political spectrum. My politics are obviously farther to the Right than, say, a Wiccan who espouses Dworkinite radical feminism and utters slogans like, "Fight the evil Patriarchy and its evil spawn, the scientific method which rapes Mother Nature."
Yeah, I think that's pretty scary, too.
I support the use of artificial gravity as well. I think Zubrin's idea of using the spent rocket booster as a counterweight was a good one.
I don't want to go to Mars to play with rocks or see a sunset. I want to help build a new civilization. Mars will never reach its economic potential until it has been at least partially terraformed.
Colonists, for their part, need to use a little forethought when considering where they establish settlements. They would be fools to site a new town in an area bound to become dangerously unstable once temperatures increase.
Aesthetic arguments are not without some little value. But to me, the prospect of billions of well-fed, well-educated, prosperous Martians enjoying meaningful peace is far more important than preserving a world whose beauty has no value without humans around to appreciate it.
As much as the occasionally Luddite opinions of radical environmentalists annoy me, I have grave reservations about using Orion-class propulsion systems anywhere this side of the Asteroid Belt. The electromagnetic pulse would surely wreck havoc on satellite constellations. The EM pulses would also cause temporary damage to the ozone layer, just as gamma ray bursts (GRBs) from distant galaxies do (but worse). As I understand it, 'pure' (nuclear fallout-free) fission bomblets are physically impossible to make. There will always be other, 'side' reactions that generate neutrons.
I totally support the use of other nuclear power and propulsion systems, though. Most people who are adamantly opposed to any use of nuclear power tend to rely on irrational arguments...nuclear energy is like black magic to them, and we're on the side of the mages.
Maybe you guys could just lease part of Christmas Island from the Australians. I hear the Russians are building a spaceport there. If members of the Earth Liberation Front chain themselves to the rocket, please give them the middle finger for me...right before you press the big red 'LAUNCH' button.
I read somewhere that an astronaut said the best sleep she ever got was in microgravity. Hopefully it won't cause many problems, in the event that artificial gravity isn't available.
I don't believe that NMD is a misguided program at all. Perhaps you never saw the photos of Russian Navy wives hanging laundry off the conning towers of nuclear submarines. They and their families were living out of the submarines, because housing conditions were so bad. There is a very real issue with the security of the world's nuclear arsenals. Sure, terrorists could try to smuggle the parts of nuclear warhead into the USA...but a nation-state wouldn't attempt it because of the catastrophic consequences if the plan is discovered before completion. And nuclear materials are not as easy to carry around as some people seem to think. Terrorists could just as easily hijack some nuclear weapon delivery system. And what would America do if New York becomes a smoking pile of radioactive ash? People would be screaming 'genocide' if we nuked the country of origin. Millions of innocent civilians would obviously die.
That's not even considering the possibility of accidental launch, as nearly happened in 1995, when Russian Strategic Rocket Forces officers loaded a training program into the early warning computers and inadvertently neglected to tell anyone else. Yeltsin had authorized a nuclear strike against America...and the whole world came within 15 minutes of nuclear Holocaust before the mistake was identified.
Actually, I read that using space-based radar, decoys can be distinguished. It's just not thought to be possible using hyperspectral cameras versus the latest camouflaging techniques. Warheads are much heavier than decoys, and that creates effects which can be measured from orbit upon separation from the booster. Only problem: We do not yet have global coverage with space-based radar (or any at all, unless it's classified).
But I'm sure that with another few Republican administrations in the USA, that will change. Just as nuclear power in space got revived by NASA, so too will Space Command get the radar sats it wants.
No one should be forced to die of starvation (or thirst, radiation sickness, et cetera) on an alien planet. Grim though the possibility might be, I'd hope they discreetly take the pills along.
Democracy on Mars, if it takes root there, will be every bit as 'crazed' as it here. Scientists have the same human strengths and weaknesses as everyone else.
Shaun, you once said that you often agree with my posts.
Allow me to return the favor and tell you honestly that I often agree with yours.
I think NASA might be trying to over-engineer MD in an attempt to 'improve' safety, but I think Zubrin addressed their 'improvements' quite effectively in "Case For Mars".
Greenspan is accountable to someone. When you disparage the democratic process as inimical to your vision of human civilization on Mars, what you seem to be saying between the lines is, "Tyranny is an acceptable outcome."
That's the vibe I'm disagreeing with here.
