Vegeta, you can add more than one pic in a post... Not that I really care, but more than 10 (almost) consecutive posts is definitely post whoring.

I know it's just for lulz, but I have a few OCD issues with that pic:

1) The zoom magically changes from a top-down view of the moon's surface, to a horizontal view. Otherwise it should've done so on the top of the moon in the 1st view.

2) There's no atmosphere on the moon, ergo no wind. So the flag should not be fluttering.

3) The zoom ratio's are all screwed up. 200x to see the moon, 400x to see a single flag on the surface on the moon, but then 800x to make the flag appear only 10x bigger.

That is all. :|

I think the fluttering effect has something to do with the reduced gravity in a vacuum.

I was hoping you'd expand on what you meant. I wasn't referring to the (do/due) typo.

Type fixed.

I meant that since the lunar surface is rocky and planting a pole there would require it being hammered in could cause the shaft to wobble and since there is less gravity and a complete lack of atmosphere, thus no wind resistance, the vibrations of the pole could create the illusion that the flag was fluttering. However some quick googling revealed the following: http://astroprofspage.com/archives/162
 
Aah, yes, that's also how I've always understood it. Due to there being no air resistance, any induced momentum in the flag (as a result of it being twisted into the ground) would take much longer to dissipate than usual. This continual movement as a result of it's momentum has resulted in the "fluttering" effect.

This effect is visually demonstrated in this Mythbusters segment (3 min).

From your original post I thought you attributed the flag's movement as a result of the moon's gravity. I apologise for my misconception. :3

The ACTUAL reason the flag looks like it's flutering is because it's held up by a horizontal bar at the top and the flag's crumple from how it was folded (in a triangle) so it looks like it's flutering in a still photo.
