Does anybody ever think how strange it is that we are living on a rock in the middle of space?

Yeah its weird when you think about and how finite we really are.  Makes me realize there has to be God and want to get to know Him.

if you could collect all the grains of sand,from every beach on this planet, that still wouldn't make up a fraction of the amount of stars out there,\nand out of all these stars,and the billions of planets surrounding them.Its hard to believe that life only exists on this little rock.

At first, I thought, 'sure' but then I realized that we know enough about Mars and after the excitement of lift off and weightlessness, I would be bored to death traveling for months, walking around in a Mars-suit all day while there, traveling for months to get back with a few oxidized rocks... \n\nSo, just save me a ticket to the ISS and I will be happy to go and spend a few weeks touring around this ol' blue planet.

I ponder that a lot sometimes, when I get completely overwhelmed by the pace of my life and the obsessive narcissism of people.\nI have this little 'shoe-box' theory: We are really at a loss to begin explaining exactly HOW BIG the universe actually is, so we may as well just be this compact galaxy, stuck at the back of somebodys wardrobe in another space and time.\nYes, I'm a weirdo...

i think that it is very important in a modern society like ours who might one day venture into the unknown reaches of space to be fully aware of our space surroundings. the moon does look pretty promising for a colony.

There are rumours that earth will no longer exist after some time because the asteroid may hit the earth.So they are trying to find other planets that supports life incase earth should be distroyed.They find mars interesting and feel that it may support life.they are trying to syudy more about this planet.I think after mars they may be interested in one of jupeters moons-for life.so dont be surprised

Yes, how could it be possible that we are the only planet that is positioned currently and close enough to a star in the entire universe?  Plus on a more spiritual aspect there is scripture upon the matter... "And by the word of my power, have I created them, which is mine Only Begotten Son, who is full of grace and truth.  And worlds without number have I created; and I also created them for mine own purpose; and by the Son I created them, which is mine Only Begotten."

At the present time, we just don't know.  If you saw pictures of aliens, what you saw were fake.  Nobody on earth has yet to produce a verifiable image, photographic, electronic or hand-drawn, of a living creature that originated elsewhere in the universe than from our home planet.  Nobody.\n\nAlso, at the present time, we suspect that there is no other planet in any nearby solar system that's host to a sentient race of beings like us.  That does not mean that some form of what we call "life" is impossible, but just think: out of the billions of living critters that now inhabit, or did in the past, our home planet, only one of those life forms evolved to the point where it (us) can even begin to think about such questions.  That by itself will tell ya we're sorta unique! ;-)\n\nIt sure would be interesting, wouldn't it?  But imagine if you will what it might be like if those alien creatures we fantasize about were an advanced race of carnivores that look upon us as another breed of cattle, fit only for eating!  Yow!  Or, how about if they were friendly, warm and fuzzy folks who just love to make nice with us - but they carry an infectious disease that there's no cure for.  Oh boy.  Or maybe, like Darth Vader, they just consider us a nusiance worthy of one blast from a super-mega cannon that blows Earth into dust?  Whoa!  Hey dude: you SURE you wanna meet aliens?  \n\nAll this is just idle speculation.  The hard fact is, even if there were creatures just like us somewhere in the universe, we are not gonna know about it, because the distances between them and us are just too great to permit interstellar travel, the hazards of such a trip are insurmountable, and no means of communication can travel fast enough for us to hear from them and be able to answer back.  Kind of a bummer, isn't it?

Odds are that the universe IS teeming with life.  We haven't been to the universe -- it's very big and most of it is too far away.

At some point we might have a colony on Mars.  The biggest problem I see is the gravity level and whether humans can live for long periods of time in 0.38 g.  Some lab mice are going to be launched into space in a satellite that can produce artificial gravity at Mars level which should give us a pretty good idea.  If it turns out that the lab mice don't survive very well then the chances of a permanent Mars colony will go right down.\n\nA small research station though could be set up on the Martian surface regardless of what the results of the Mars Gravity Biosat are although having Earth gravity stations in orbit over Mars to rotate the researchers to every so often would probably be a good idea if Mars gravity isn't good for humans.\n\nI suspect most of the activity in space in the future will be concentrated away from planets and in artificial structures that spin to provide gravity that are built from asteroidal resources.  Mars colonisation if it is possible would probably be a lot faster if space settlement has progressed than in a solar system without space settlement as setting up a colony on Mars would basically require the same amount of stuff as you'd need to build a space settlement except that you'd have to move it all to Mars and soft land it.\n\nAs for when it'll take place, probably towards the end of this century although we'll only know when the first Mars colony is built.\n\nTerraforming Mars and keeping it terraformed is going to take a lot longer than building up the equivalent surface area in the form of space settlements.  Not that I expect that to stop anyone (the science we could learn from it would probably be enough to justify terraforming Mars) and by the time we start we'd probably be able to afford to move comets to Mars.\n\nStill, it won't stay terraformed unless we maintain the planet unlike the Earth which has managed to do so for many billions of years.

I have beein inside the end of the rainbow on one occasion, and no it was not in my drug experimental phase of young life. \nWe were camping and ti rained and there was a rainbow and it wasover the area of a camp ground we were staying at for a vacation. \nI even took pictures of the way everything was colored. It was so strange and really not very pretty at all. All kind of golden in color and then another and another and  if we had not figured it out really quickly I would have sworn we were in some kind of alien tractor beam or some such stuff. But luckily my Aunt was quick on the uptake and after she figured it out we all just stared at it. It did not last long at all, but the camera was handy and she took pics of it while it lasted.\n\nStrange but true facts from the lower regions of Arkansas, where\neven Big Foot likes to call it home! LOL!

As above, the water, atmostpheric pressure, and temperature aren't concducive to human life. But there's another issue: response time. Right now, we have the technology to build a station on Mars. But if something went wrong, it would take us two or three years to get a repairman there!\n\nBecause it takes so long to get there, any settlement on Mars would have to be COMPLETELY self-sustaining, and that's what's really holding us up. (We couldn't even keep the International Space Station going as long as it should have).

Yes.  There is a very small amount of matter that enters the atmosphere from space (meteorites), but essentially it is all just being recycled. Some atoms of oxygen you breathe in may have been breathed by a dinosaur, or one of the pharoahs!

are you living in Mars??

It seems very possible that asteroids seeded this planet with life. That might have not been as accidental as some people think.
47051
not in our solar system. \nBut you also have to remember that even if there is life on other planets, we are assuming that they are as advance as we are or more. Could it be that maybe they are in a pre-industrial era and have no means of space exploration?

It is indeed possible...I'm just not sure on what planet.
