We can either project our vision of the future of space exploration or allow some other nation to project theirs.
Our choice is simple, Lead or Follow.

Extremophiles have been found that can withstand massive doses of radiation, breath rust, eat sulfur, belch methane and live without oxygen or sunlight.

I don't know what "breath rust" is, but if you have it, I recomment lots of tic-tacs...

Life will find a way.

It does indeed. A keynote speaker at a USENIX convention shared a story of a split brain human subject. The subject's brain had been surgically split into left and right hemispheres with a slice through the corpus callosum. The brain performs different processing tasks on the left and right hemispheres. The surgical cut prevents the hemispheres from directly cooperating.

The subject was given tasks that normally require some left/right coordination. After a brief time, the subject was observed tracing out patterns in the palm of one hand with a finger from the opposite hand. The loss of direct communication via the corpus callosum was being replaced by a mechanical/tactile path with fingers and palms.

Count every single grain of sand on every beach surrounding every content on earth.

If those grains were stars, our Sun would represent one grain of sand. I am no UFO chaser by any means but the odds are too overwhelming....

We should have been off this backwater hole thirty years ago. What is the holdup?

There's no national will to do it. Indeed, there's a growing trend to ridicule space exploration and science in general in this country. Sad stuff.

The worst things are hemispherectomys, where, in extreme cases of epilepsy an entire hemisphere is removed. Patients interestingly enough (if the operation is done at a young age), can sort of lead a life that you wouldn't think possible.

As for life in the universe- I'm glad people are finally getting away from the idea that you need liquid water to sustain life. That's actually funny. Who knows what is out there. A biologist once got into a debate with me about that, but I said that if a flourine-based life for walked up to me and bit me on the behind- I wouldn't disbelieve it's existence.

And yes, I agree that we should have condos on Neptune by now. At the first manned moon launch, there was a crowd of about a dozen protesters that had signs saying that we should put the money for space exploration into social programs. They were ridiculed back then, but not any longer.

Look at the Russian Topaz nuclear rocket technology- we can't even begin to play with great tech like that without Whoopie Goldberg or Elton John types blowing whistles and halting production. And then there is the super collider being built in Europe, is it? That's shameful.

Yeah, social lefties are one of the sources of the anti-space sentiment. The general anti-science sentiment, however, is fueled from another stratum of our society.

Both groups are wrong.

Still thinking small. Compare the size of a grain of sand with the size of the earth. That is more or less the size of the Hubble volume compared with the entire universe.

Do you really think it's a growing trend, or do the willfully ignorant now just have a louder voice with today's technology? I've often wondered which is really the case and can't honestly say I know the answer.

The general anti-science sentiment, however, is fueled from ... disappointing results from scientists.

Scientists can recover their stature with results.

"Twenty years to fusion..." I believe that mantra started in the fifties.

Dig into a mucky river bed and you find bacteria living on hydrogen sulfide. There are many obligate anaerobes on this planet.

This gravitywell-centric view always ticks me off.

If a race has the means to travel beyond it's solar system it certainly has the means to prosper without planets.

As an example, who knows what the Super Collider would have discovered. But the luddites saw fit to destroy it. Many of the "disappointing results" are from funding cuts and cancellations. I am paid by the Gov and I wonder if each year my projects will be re-funded.

And who knows- if you actually ran into a life form out there- you might even be confused to call it "life" in the first place- hence the term "alien." The idea that intelligent life breathes 02, speaks english and has to have metal clunky spaceships with engines is laughable. There are lots of ways to move around, and lots of ways to live.
