8. Because its there "Adventure. Delight. Increasing the depth and breadth of human experience." (UK LeGuin).
9. International pride "Tomorrow, together, where might we not go?" (Frank Borman) 10. Impetus to technological development (George H W Bush, 1989) 1 is really a subset of 7. Nation of choice can be substituted for USA in 4. |

The intent of this thread was to have everyone list the choices in order of priority, highest priority first. Specify your criteria, such as “What I think the priorities should be”, or “What I think the actual priorities are now”, or “What the priorities will be in 10, 20, 30 years” etcetera, etcetera, etcetera.

ICMO, the priorities should be:
6. Security for Mankind: 3. National Security: 4. National Territory: 5. Economic: 1. Alien Life: 7. Just plain human curiosity: 2. National Pride: 10. Impetus to technological development 9. International pride

I think Security For Humankind should come before National Anything.
In the semi-long run, Archeological Conservation of Human Artifacts on the surface would be something to focus on.

The question is: What should the priority be, vs what is it likely to be? Many opinions have been offered, but realistically, what will be the inevitable driving force to get humans to Mars in person?

Priorities :
8. Because it is there , for the thrill of doing it. 7. Science exploration 1. Alien life in fact 1 is really a subset of 7 as said JC 10. Improving our technology. learning living in space by doing it. I don't believe mars can be a lifeboat for Earth. The Earth future is on Earth. I hope competition between the nations and war will not be brought to the heaven. |

In decreasing order of importance
8 (if people can go to mars one day they will, even if there is no reason for it, just like climbing Everest) 1+7 9 nationalism is silly and regressive on the solar system scale 5 (assuming we can find anything to make money from) 6 (assuming we can settle there) 10 will happen anyway The others I would not even dignify by mention Jon |
|

|
4, and I'm not an American.
The best thing that could happen for humanity's expansion into space is the US withdrawing from the Outer Space Treaty, claiming chunks of land for itself and doing something, however minimal, to defend it from foreign landings. |

Yes, and other countries would be bigger. So? The situation presented is not analagous; our potential living space is not limited to a continent. Plenty of Universe for everyone.

Whatever you say. However, although the Universe may be essentially limitless, the only current practical planet to colonize is Mars, severely limiting the available off-planet realestate.

So who needs planets? Space habitats are more practical and have a clear title; whoever puts up the money to build it owns it. According to the Outer Space Treaty, although nations can't claim ownership of asteroids or moons, anyone who mines one can own whatever materials they remove (A wacky law birthed from Cold War politics) and can build what they want from it. Why bog down in a gravity well when 1-g is only a spin away?

Geez, you don’t see the relevance? We find ourselves at a juncture in history, and a major juncture at that. While our forefathers did not necessarily grasp the full significance of laying stake to as much territory as possible when the circumstances presented the opportunity, it is fortunate (for the USA) that they chose to incorporate as much territory as possible into the Union. Relatively small decisions 200 years ago made tremendous differences today.
Imagine a lackadaisical approach to the colonization of Mars. The Chinese, or the Indians, or whoever, claim the majority of Mars as their territory. Although that may not seem significant now, a few hundred years down the road it could conceivably result in a dramatic change in the balance of power. Imagine if you will the Chinese telling the USA that the US colony is on Chinese land, and that they must leave immediately or pay taxes to China. Although there are some who would find this either humorous or possibly justice, I assure you that we would not take it lightly. IOW, it would be better to at least preeminently claim territory, than to be kicked out by others who were simply more aggressive in their approach.

We "know" that in a few hundred million years the Earth will present a difficult environment for our survival. Whenever that time comes at which we (our descendants) must abandon the Earth in order to survive, we will need the technology and skills to do so. These will not be acquired "overnight". We can't be sure we know of all the hazards that may befall the Earth (collision with a large asteroid, toxic "bloom" of microbial pathogens, genetic engineering gone wrong etc.,), so the sooner we develop the required technology and skills for robust interplanetary and interstellar travel, the more safe we will be. Whether by design or the luck of the draw we have a solar system that lends itself to the development of space transportation--huge fuel tanks in the gas giants and a star that emits enough energy that we can harness to propel us onward and outward from our place of birth.
With this in mind the top priority for Mars missions must be (or become) the support of the development of the technology and skills required to travel safely and comfortably between planets and stars with sufficient robustness to build, terraform, and colonize planets anywhere in the MW that we wish. In support of this "grand theme" the set of priorities listed previously must be set aside in favor of a set that supports the development of the technology and skills cited above with the colonization of Mars used as a proving ground and qualification test bed. Such technology and skills will take from hundreds to thousands of years to develop to the levels of safety and comfort required for space exploration. Since I am convinced that worm hole exploitation, space folding and zero point energy harnessing are fictional concepts, fusion and matter/anti-matter sources for energy are unproven and are likely to remain risky for hundreds of years, and fission energy sources for ships carrying sufficient propellant mass for interstellar travel of 5 light years distance are "unwieldly" at best; I believe the only viable system is one incorporating power on the order of 10^18 watts beamed from near the sun from polar orbiting beam generators to beam riding vehicles with adequate photovoltaic receivers to provide thrust to ion engines and propellants provided from the gas giants via particle beams. Very important criteria for any system traveling between planets or stars is the ability to detect and avoid obstacles and to achieve orbit at destination. These criteria remove the option for coasting. If the design details for such a system can be solved (beam focussing is a bear) at all, it will surely take tens of years to design and hundreds of years to test and implement. Time's awasting!! Motivation based on ego feeding and curiosity won't get us there. Fear of aliens of hostile intent may help, but I hope we can avoid both the aliens and the fear until we develop the strength required for us to be hospitable neighbors. We must think in terms of benefits to our descendants living thousands of years from now.

1. Scientific investigation and the expansion of human knowledge
2. Aerospace R&D stimulation. 3. Thrill of exploration and discovery. 4. A satisfying sense of accomplishment. I don't think there's anything to be gained here on Earth, militarily or economically, from missions to Mars (except perhaps as a side effect of 2, above). It's not like a military base on Mars would be able to alter the course of battles here on Earth. And resources extracted from Mars would almost certainly cost more to send to Earth than they'd be worth on arrival. At some point, of course, the human civilizations on Mars might be well enough established to develop their own self-sufficient economy and support their own local military-industrial complexes for the purpose of waging war against each other. But that's a whole different situation than our current Mars mission priorities... Last edited by stutefish; 15-December-2007 at 12:36 AM.. Reason: pluralization error |

Most likely everyone who contributes to the program will have their own motivations and priorities. As with most large-scale projects, there will be a lot of compromise on that front.

I think the driving force, at least for the first mission, will be a combination of curiosity and national prestige. And sheer stubbornness, since we've already said we'd go and don't want to be proven wrong in front of the rest of the world.

Determining if terraforming is possible. It may sound like ridiculously forward-thinking, but pretty much all space exploration falls under that category doesn't it? If we want a permanant, self-sufficient colony it needs outdoor agriculture. Humans simply require too much land to sustain them for the glass domes we see in artists sketches to support a significant and growing population.
As far as I can see, we don't even know if Mars can be terraformed. Are there enough volatiles to form a biosphere? Even with greenhouse gasses, can the temperature be raised enough? Without a magnetic field will Mars be able to retain a new atmosphere without massive and continuing development?
