Lichen Can Survive in Space: Space Station Research Sheds Light On Origin of Life
Science Daily ^ | 23 JUNE 2012 | reprinted from materials provided by European Space Agency

Posted on 06/24/2012 12:18:06 PM PDT by onedoug

...When astronauts venture on a spacewalk, hours are spent preparing protective suits to survive the hostile conditions. No effort was made to protect the bacteria, seeds, lichen and algae attached to the outside of the Space Station, however.

....

Lichen have proven to be tough cookies -- back on Earth, some species continue to grow normally.

I've been interested in the origins of life for some time, so this seemed very interesting to me. However, evidence for this from meteorites has only yielded prebiotic materials with the controversial possible exception of Allan Hills 84001.

This latest information though, would seem to indicate mateorite transfer to Earth as a strengthened possibility.

“I’ve been interested in the origins of life for some time, so this seemed very interesting to me.”

If you are that interested I suggest that you read Genesis.

The world-renowned crusader for Darwinism and atheism, Prof. Richard Dawkins, states:

‘We have seen that living things are too improbable and too beautifully “designed” to have come into existence by chance.’

I read Genesis every year by virtue of the Torah cycle, and have no problem at all relating it with Robert Hazen’s “Genesis: The Scientific Quest for Life’s Origins”.

God turns up in the universe’s most fascinating places: all of it.

The only thing I got out of it is that lichen can survive in space for a certain amount of time. Anything beyond that is just speculation.

It’s all very simple. Live can live in and on rocks ~ both fungal and bacterial life forms (which are incredibly different), and that means that given 13 billion years to work with, life could have traveled quite a long way to just about everywhere.

On one of the space pings, someone figured out that our Voyager spacecraft, launched in the ‘70’s, would take just short of 100K years to reach Alpha Centari, the closest star outside of our solar system at present speed had they been aimed for an intercept course.

I find it hard to believe anything would survive the time, vacuum, cold and radiation for anything approaching that amount of time.

Mhmmm. Until life gets created out of nothing (impossible) in a science lab, you can chalk all of this up to impotent speculation. Real science is based upon observation, can be duplicated, and is refutable. Anything and EVERYTHING related to a time before we can observe, and have no record of, is pure fabrication, a big, fat, whopping lie, scientifically. This mumbo jumbo, and all other theories of evolution are mere scripture from the liberal church of the godless.

If Earth life can survive in space, so can alien life; & the origins of life on Earth & the Universe could be far, far away.

n contrast, the space samples endured the full power of the Sun's rays. The samples were insulated somewhat by the Space Station but still had to cope with temperatures changing from -12ºC to +40ºC over 200 times as they orbited Earth. Wow, they survived in temperatures of ten degrees Fahrenheit to 104 degrees Fahrenheit. I would like to read the paper this piece was written about.

Nothing comes from nothing.

I once assumed that nothing had preceded life’s reproduction. That is, that it had occured de novo, spontaneously with the onset of life. Now however, I suspect that the essential patterns were already laid out, i.e., “tried” if you will, by the replication, and even evolution, of several types of prebiotic molecules.(Ref. Hazen, #4 above)

Quite a few of these molecules figure prominantly in later biological sequencing of RNA and DNA, as the most prominant.

Given the sophistication of organic chemistry at this level, I’d even venture as to wonder whether God was working it out in His own “mind”.

It’s very compelling to wonder...at least for me. And I think God would understand and appreciate humanity trying to reason it out too.

I’ve got to admit that I was a little disappointed not to see the lichen experiments referenced in the paper the article cited, although the molecular sequences cited are still interesting.

A little further down of the same Science Daily page is a link to an article “Tiny Animals Exposed To Outer Space”. As it’s evidently from 2007 though, I suspect they didn’t fare too well. It will be interesting to dig up something on this, as I’ll try to do.

May I suggest two books?

Michael Denton entitled: Evolution: A Theory in Crisis

Michael Behe book entitled: Darwin’s Black Box: The Biochemical Challenge to Evolution

um... I think any lichen attached to anything would burn up entering the atmosphere.

And plus this silly explanation doesn't explain the origin of life... it's just a cop out by saying it must have started elsewhere.

Personally, I think that Earth life began here. Yet even were it true that life began elsewhere, we’d still be compelled to ask, how and why? But I don’t doubt that the chemistry for life is ubiquitous and that at least “simple” biology could be too.

I’ve read them. And I’m using the term rather loosely. I know there are a lot of specific issues involved and don’t necessarily go along with all of them without question.

Still fun to speculate and I'm not about to budge an inch in the face of any bluenose baloney.

We already know there are bacteria buried in rocks deep within the earth. Their metabolism is so slow they could live tens of millions of years without running out of their available nutrition (from the rocks).

Evolution is a totally different story. It probably doesn't work like anyone has yet imagined. Odds are good we'll figure out how to tap into it soon and adjust genomes to eliminate genetic disease AND all unapproved changes.

The first flaw in Darwinian Evolution is the postulate that we have a common ancestor.

Actually, we don't need to have a common ancestor if life spirals in from outerspace in all directions all the time.

Claiming that life came here from someone where else on an asteroid does not prove the “origin of life”. It would still leave the question of how did the life come into being before it attached to the asteroid. The theory of life coming here from somewhere else is a cheap attempt at misdirection to stop the questions about the origin of life, which evolutionists can’t answer. They hoped this would shut people up.

I agree life could appear in many different places. If so, & with the revelation that life can survive space, Earth may be colonized by native species as well as alien species. There may have been interbreeding. Perhaps plants or animals, which are fundamentally different, are alien, while the other is native.

Life surviving the vacuum of space is a big thing!

So is the order of things. Order and disorder “exist” simultaneously, which us why the Greeks started trying to puzzle out things and create what they called philosophy.

“It’s very compelling to wonder...at least for me. And I think God would understand and appreciate humanity trying to reason it out too.”

Me too, but at that point we get far beyond the realm of physical science, and deep into faith. “With God, all things are possible,” Moses turned a stick into a snake (through the power of God), and back again, among many, many other “miracles.” I prefer to call it the “Science of God.” He knows how to do it, and, I believe, sets up the natural laws in which we operate, which may not even be the same for one region of space to another (No one knows, and will EVER know, until/unless He revels it to them, but it certainly won’t be tested out). I’m quite certain that it is impossible for us to know something that happened before we existed, without inspiration/revelation.

Now, people can have a theory, but in science those theories can be disproved, but NEVER, EVER, EVER, proven correct. Affirming the consequent isn’t even good logic anyway.

I would say a study of the complexity Bacterial Flagellar Motor alone would would be convincing, but I some how doubt it.

I will never get the foolish “read the Bible as ever word is literal” folks...

Change, by its very existence is proof of God.

The second worst days for humanity was the day some ignorant slob became literate and was unable to discern allegory from literal when it came to the Bible. The worst day, was when he was able to convince other ignorant slobs to follow his ignorant belief.

God gave man REASON and the desire to understand the universe, only the ignorant would argue not to pursue those things.

The idea that science and religion are mutually exclusive is idiotic, and only those relatively ignorant in one or the other could believe such a thing.

Flageller motor? Pshaw!

Bored to 3.625, stroked to 4.625, ported D shaped intake and exhaust ports, 42 mm mikuni carb, matched intake manifold, geared at 3.28, free flowing LSR pipes, grab a handfull and feel the torque zero to 100 before you can look down to see what it is, only took 109 years to evolve.

You don't give the primary planner sufficient credit for those flagellate motors.

That’s the very first thought I had...even if some microscopic life form made it to Earth, how could it possibly survive the inferno of getting through the atmosphere?

Thanks for posting this article.

As regards to nothing from nothing, I think the concept of nothingness interesting. The Cassini Effect sort of illustrating the idea.

Going way before life, looking, in the very large scale, at why there’s anything at all - precursors to life - the Broken Symmetry hypothesis is also very interesting to explore.

"Nothing comes from nothing."

Language hobbles us in this type of discussion. For instance, what do you mean when you use the word "nothing"? Do you mean complete absence of all disorder, a blank uniformity of everything, no matter, no energy, or something else?
