I for one think it is highly improbable that humanity will ever be wiped out completely. In one big haul, that is. You don't just get rid of seven billion intelligent critters.
Cretaceous-Tertiary extinction, End Triassic extinction, Permian-Triassic extinction, Late Devonian extinction, Ordovician-Silurian extinction. Those are some of the most massive extinction events in this planets past. In some cases almost every species living at the time was wiped out. I'd rather be safe than sorry.

What we can do is make sure that the remaining humans can't ever climb up the ladder of progress again.
...You can't be serious? If the problem is to difficult to solve, just pull a Stalin'esque move and control every facet of everyone's lives?

Space travel is something that we should do, but we are not ready yet, and we are certainly in no rush, aiming to get to mars within 10-20 years is uncessary and holds little if any benifit.
Ask yourself this question: what good has all of our amateuristic space exploration done for us so far? Oh sure, we now have GPS and a gazillion of worthless television channels, and we can bug each other with our mobile phones. We also now have pens that can write upside down (really handy on Earth, you know) and bras that still support women's titties in zero gravity conditions (again, so useful on Earth). The only real positive things are stuff like the Hubble Space Telescope which gives us the opportunity to peek into the darkness and see things we never saw (and make pretty pictures of it). That's about it, dude. And do you have any idea how much all of that has costed us? Not in dollars, but in energy? Too much.
DIGITAL IMAGING BREAST BIOPSY SYSTEM - The LORAD Stereo Guide Breast Biopsy system incorporates advanced Charge Coupled Devices (CCDs) as part of a digital camera system. The resulting device images breast tissue more clearly and efficiently. Known as stereotactic large-core needle biopsy, this nonsurgical system developed with Space Telescope Technology is less traumatic and greatly reduces the pain, scarring, radiation exposure, time, and money associated with surgical biopsies.
BREAST CANCER DETECTION - A solar cell sensor is positioned directly beneath x-ray film, and determines exactly when film has received sufficient radiation and has been exposed to optimum density. Associated electronic equipment then sends a signal to cut off the x-ray source. Reduction of mammography x-ray exposure reduces radiation hazard and doubles the number of patient exams per machine.
LASER ANGIOPLASTY - Laser angioplasty with a "cool" type of laser, caller an excimer laser, does not damage blood vessel walls and offers precise non-surgical cleanings of clogged arteries with extraordinary precision and fewer complications than in balloon angioplasty.
ULTRASOUND SKIN DAMAGE ASSESSMENT - Advanced instrument using NASA ultrasound technology enables immediate assessment of burn damage depth, improving patient treatment, and may save lives in serious burn cases.
HUMAN TISSUE STIMULATOR - Employing NASA satellite technology, the device is implanted in the body to help patient control chronic pain and involuntary motion disorders through electrical stimulation of targeted nerve centers or particular areas of the brain.
COOL SUIT - Custom-made suit derived from space suits circulates coolant through tubes to lower patient's body/ temperature, producing dramatic improvement of symptoms of multiple sclerosis, cerebral palsy, spina bifida and other conditions.
PROGRAMMABLE PACEMAKER - Incorporating multiple NASA technologies, the system consists of the implant and a physician's computer console containing the programming and a data printer. Communicates through wireless telemetry signals.
OCULAR SCREENING - NASA image processing techniques are used to detect eye problems in very young children. An electronic flash from a 35-millimeter camera sends light into the child's eyes, and a photorefractor analyzes the retinal reflexes, producing an image of each eye.
AUTOMATED URINALYSIS - NASA fluid dynamics studies helped development of system that automatically extracts and transfers sediment from urine sample to an analyzer microscope, replacing the manual centrifuge method.
MEDICAL GAS ANALYZER - Astronaut-monitoring technology used to develop system to monitor operating rooms for analysis of anesthetic gasses and measurement of oxygen, carbon dioxide, and nitrogen concentrations to assure proper breathing environment for surgery patients.
VOICE-CONTROLLED WHEELCHAIR - NASA teleoperator and robot technology used to develop chair and manipulator that respond to 35 one-word voice commands utilizing a minicomputer to help patient perform daily tasks, like picking up packages, opening doors, and turning on appliances.
Other spinoffs in this area include: Arteriosclerosis detection, ultrasound scanners, automatic insulin pump, portable x-ray device, invisible braces, dental arch wire, palate surgery technology, clean room apparel, implantable heart aid, MRI, bone analyzer, and cataract surgery tools.
That is just a few of the medical benefits
directly from NASA. You might want to reconsider your statement.
Those that beleive we are not ready to travel into space need to truly understand the implications of that belief. I've clearly stated the benefits of space flight above. If you would like me to paste a few more, I'll fill this thread with pages and pages of inventions from NASA that are in no way trivial or worthless. Exploring the "New World" was not trivial or worthless yet many at the time thought it was a useless area good for very little. Those that saw value in the Americas flocked there, they made a new home for themselves and thrived.
There are those that will say, "We have to many problems here on Earth that we need to address before "wasting" our resources in space."
Since we've addressed that we are not in any way wasting resources lets answer if we are ready to venture into the great unknown... During the Apollo missions NASA employees had a saying, "If we can go to the moon we can..."
You finished that sentence with your own dream. If we can go to the moon, we can cure cancer. If we can go to the moon we can end a war. If we can go to the moon we can create a better union. It was the challenge of landing on the moon that gave the inspiration to better ourselves and all of humanity. It was one dream shared by the world and if that one dream could be shared by so many different people, if we could accomplish the impossible... Then nothing was out of our reach.
Mars and space flight in general offer a similar dream.

Don't forget that the Space Shuttle program (the only space program that relied primarily on liquid hydrogen instead of petroleum-derived fuel) is getting cancelled. It's not adventurous enough to the public, because Space Shuttles never really leave Earth.
The space shuttle is being replaced. As cool as it is fixing up the ol' fastback there comes a point when you have to move on. Were we to continue using the space shuttles we would have move Columbia and Challenger disasters.

Reminding people of the Apollo program is simply part of the Presidential campaigns that are still going on right now. Kennedy is still considered a real American hero because of it and making similar statements (let's put a man on the <strike>Moon</strike> Mars) is just a stupid attempt to have some of that Kennedy charm rub off on them (Obama/McCain).
I have not seen either candidate mention anything of the above. In fact Obama has indicated cutting NASA's budget. Yet, I "will not forget my dieing King."

It's a cheap fucking tool to tell their voters that high goals (e.g. putting a man on the Moon -> shift from oil as a primary fuel source) is possible if we (i.e. the yanks) as a people commit ourselves to it. And just like pretty much everything that comes out of the US of A these days, it is a load of crap. Look around you: do you see change? Do you see the majority of people get rid of their cars and use their bicycles instead? Do you see them consume less? Have you noticed a sudden drop in the fabrication of plastic and other chemical crap?
No, you haven't. What you are seeing are small-scale actions and often ludicrous events (e.g. "This weekend is healthy bicycle weekend!" W00t!) organized by an absolute minority. And guess what? That's not new. There have always been smaal groups who did stuff like that, but it didn't bring any change at all.
You've got to start somewhere, you say? Sure, but that start was already taken decades ago (Greenpeace, etcetera) and it just didn't get the results we need for our future and that of our children.
Politicians know this. Politicians know that their voters are lazy, stupid, meek sheep. And sheep need a leader who will tell them that (s)he will solve all of their problems just like that WITHOUT creating bigger ones. That's where the main problem is situated: you can not solve this crap without creating bigger problems, and bigger problems (to the masses) are: having to pay more taxes, and having less money to spend on the pollution of this planet (i.e. consuming like the little whores we all know we are).
Solution: let's at least make it appear as if the leader(s) are doing something substantial: let's say that everything and everyone (especially big corporations, but also all governmental institutions) are concerned with durability and sustainability. WHILST THEY ARE NOT. Let's feed the young lies so that they will learn how to grow old.
I can not fault you on this however its tough for people to change when their own leadership warrants more fossil fuels over alternative energy sources and refuses to sign greenhouse reduction pacts with other nations. Do as I say, not as I do applies? No?

I'm ranting about this because it has become my dada over the past few years. We are at an incredibly crowded crosspoint in history right now and if we do not make harsh decisions (take the right turn) we are not going to survive. We'll get run over and that will be it.
You stated earlier that what you just said was highly unlikely; however, I do agree with you here. I do beleive we need to make drastic changes to improve our situation and reduce the possibility's you and I both fear.

Real change would be to rob people not of their money but of their lust to consume. And seeing how 'politics' has become synonymous with 'economic growth' that is not going to happen before it's too late.
As I'm sure you know, that is not possible and morally objectionable. We are consumers by nature, that is what we are and that is what capitalist nations need in order to survive. What we need is to consume less energy but our lifestyle would change very little. A good example would be energy efficient light bulbs. What was once 100 watts is now 23 watts. That is the scale of change we need for all of our consumption.

So fuck the Space Program and let's focus on what's really important: how can we wake up 7 billion people and teach them this one truth: we have one planet only and if we don't save it, we are forever fucked. That's gonna cost heaps of money, so let's not waste it on some science fiction daydream that, all in all, will probably not add much more to human life than a pair of boxershorts that resist radiation (very handy on Earth) and suglasses that can withstand micro-meteorite impacts (again, useful for laying at the beach, yes?).
My two-hundred-and-twenty-six cents.
Since I've all ready given a rebuttal to the above I see no sense in repeating myself but will add this. If we seek to better ourselves, if our principle in life is to create a better world for our children and our childrens children. Then we need to explore our options. We need to strive toward the other planets in our solar system. The more we learn about them we see what we may one day become, barren, lifeless, cold a wasted opportunity. Those empty bodies in our solar system are constant reminders of how fragile life is. That if the principle mentioned above is in jeopardy, be it from over population or some other potentially destructive event, we will need an alternative.
There is no refuting the fact that we need to become a space faring species. Just the same, there should be no refuting the fact that we can become one while solving our problems and where ever possible using what we learn from the universe to benefit our continued survival.

I think we're going to return to the Moon first because it's nearer. And makes more sense. Colonizing the moon is kinda like sending a soldier to the Boot Camp (the moon) before sending him to the front lines (Mars). The Moon is the nearest place of interest, I bet you can and will see it from your windows in two or three hours, maybe you're already seeing it. Mars is pretty far away. The Moon? Compared to Mars, going to the Moon is like walking to the nearest bus stop. We need to LEARN what works and does not works when it comes to space colonization. Then we can head for Mars or Venus.
Alec has all ready pointed out the various troubles with a manned mission to Venus; however, thats not saying that it would not be a good idea to go there.
I do believe that we need to use the moon as a staging facility but towns on the moon is just idiotic and I'm embarrassed to hear such a high authority at NASA suggest such a thing.

And why is the NASA still using those ridiculous chemical rockets? Goddamnit. We use nuclear power on ships and submarines, but to go to space we are still using Chemical Rockets? Holy shit. Nuclear Power with Solar Power as support would really help to go to Mars or the Moon faster. Chemical Rockets don't cut it. And Greenpeace anti-nuclear eco-nuts can go to hell. We need more nuclear power everywhere, and why not start with space?
NASA is right there with you. In fact, there are many nuclear powered vessels as well as solar propelled ones. As we speak there is an ion/nuclear vessel heading toward Jupiter!
Unfortunate turns of events in Russia and America have not endeared the public much to the thought of nuclear anything. While unfortunate there still are other forms of energy much more efficient with no pollution in the works. Part of me fears creating mini-stars on the planet surface but hey, what a way to get a tan if things go wrong eh?!

And for those who say there's no need for space colonization... Space is the creepy, dangerous ocean of today, like the Atlantic was so frightening to the europeians before Colombo and Cabral.
I don't think very many are afraid of space more so afraid of how we will change because of it. Then, there are those that feel exploring space is a waste of time...
