India to launch Chandrayaan-1 moon mission in October

The spacecraft is scheduled for launch on October 22, five years after the Indian government cleared the project. It will make an entry into the lunar atmosphere for a two-year mission.


Did I just read that right? Maybe it's a translation error or maybe it's a telling slip of the tongue!

The moon has a limited atmosphere. All large bodies capable of sustaining gravity also have limited atmospheres (this might be just a few molecules per metre but its still classed as atmosphere.)

Maybe they meant the "heavily laden with conspiracy" atmosphere that surrounds the moon?

There is a very slight atmosphere on the moon- nothing substantial or else we wouldn't be able to see the mountains and craters as clearly as we do- a thick lunar atmosphere would distort them!

I don't know. Earth's atmosphere is pretty thick, yet we can make out all kinds of stuff on earth pretty clearly from space.

Edit to add: This brings up another point I've just thought about. Why, when you view videos shot from space, of the dark side of the earth, don't lights on earth "twinkle" like the stars do? You would think that the "twinkle" would work both ways, if it was due to atmospheric distortion.

I think theres a strong possibility that the link you provided fits the case better, which would actually make the moons atmosphere 2/3 of ours. I don't believe its breathable as Mr. Lear maintains however, there is a notable lack of water and plant life. I also do not concur with his current credo that the Apollo landing was a hoax, as due to the atmosphere, they didn't have enough fuel for the return trip. There was no reason to hoax this, no one twisted their arms to actually set foot on the moon, but depending on what was on the moon, there are many reasons to hide the truth.

You can also easily spot earth's atmosphere when looking at the earth's limb from space. The blue haze of the atmosphere at the edge of the earth's image is unmistakable, in fact.

It becomes even more obvious at modest magnifications:

So the question I must ask anyone who thinks the moon has an atmosphere is this; where is it? It does not show up in any high resolution photos at all. There's no haze, there's nothing at all to indicate the presence of a lunar atmosphere. If there were anything there at any reasonable fraction of earth's atmosphere we should see something.

Because lights on earth are nowhere close to being point light sources as viewed from earth orbit - light from cities tends to clump together. Even lit street lights clump together as seen from space. Therefore, we shouldn't expect them to twinkle any more than we expect planets to twinkle.

Im not quite sure I understand that part of your post.. which trip to the moon are you talking about that didnt have enough fuel for the return trip.. as far as I know.. they went to the moon nine times.. there was one trip.. where they had to turn back.. because they were running low on oxygen to breath.. they made a movie about it.. .. is that the one you meant??

Have you ever looked through a telescope? The images even on a good night are far from crystal clear even from the tops of mountains. The earths thick atmosphere distorts planetary surfaces and deep sky objects etc. Also from space the Earth's atmosphere is visible as a 'halo' around the Earth.

Now, if the Moon had a substantial atmosphere the craters and mountains would show erosion and changes, dust storms and clouds would blow up. Indeed the whole surface would change and we would have to draw up revised Moon maps. The fact is we don't, the maps of the Moon made in the 1800s are just as valid today because the lack of atmosphere means that the Moons surface never changes- don't forget Mars has a very small atmosphere but we can see the dramatic changes from here on Earth with small telescopes even at this distance! Imagine the changes we would see on the Moon this close!

If the Moon had even a slightly substantial atmosphere it would be obvious, epsecially during an eclipse- as the Moon passed in fron of the sun it would illuminate the lunar atmosphere creating a halo effect around the Moon. Again, this doesn't happen as there is no substantial atmosphere.

That's the quality of the video- they do twinkle slightly but not as much. Don't forget stars are much more powerful! Moreover they are a long way away. Not all stars twinkle the same amount either- stars high up in the sky hardly twinkle at all while the ones low and the horizon really sparkle- this id due to the fact that starts lower on the horizon are passing through more of the Earth's atmosphere and their light gets refracted more than than the stars overhead. So, lights from cities are like the stars overhead only a small amount of refraction. If you were to see them on the earths 'horizon' in space I think they would twinkle much more.

Hope this helps! I should steer clear of the Moon has a thick atmosphere nonsense if I were you- it's just not borne out in reality!
