The rocket was throtlled down for landing and the overal pressure of the exhaust was close to 1 PSI. Also, they usually cut off the engine a few feet above the ground. There is however some scouring of the surface dust and that is visible in photographs. [quote:geerod:MV8yMDgzMTE2XzM1MDg3MDY4X0NEQ0ZGQzY3] the rocket exhaust should have left a crater under it NO?[/quote] no. [quote:geerod:MV8yMDgzMTE2XzM1MDg3MDY4X0NEQ0ZGQzY3] also no moon dust covering the nice clean aluminum covered landing pods.hum???????????? [/quote] Why should there be? First, it isn't true that there is no dust. There is some and that can be seen in some photos. There isn't much though because the rocket and dust were in a vacuum. And dust kicked up wasn't suspended in the air like it would be on Earth. It doesn't hang around like we see when dust clouds up here on Earth. It falls quickly. The rocket exhaust carried it quickly away from the landing site so very little landed on the pads. Also, again, the rocket was usually turned off a few feet before touch down meaning even less chance for any dust to hit the pads. [/quote] ^This x10000!

[Armstrong, from the 1969 Technical Debrief - "I first noticed that we were, in fact, disturbing the dust on the surface when we were something less than 100 feet; we were beginning to get a transparent sheet of moving dust that obscured visibility a little bit. As we got lower, the visibility continued to decrease. I don't think that the (visual) altitude determination was severely hurt by this blowing dust; but the thing that was confusing to me was that it was hard to pick out what your lateral and downrange velocities were, because you were seeing a lot of moving dust that you had to look through to pick up the stationary rocks and base your translational velocity decisions on that. I found that to be quite difficult. I spent more time trying to arrest translational velocity than I thought would be necessary."] [/quote] Has nothing to do with what weasel was talking about. He was talking about dust on the tops of the footpads. It didn't billow and come to rest on the foot pads the way it would if there were an atmosphere. [/quote] so it was kicking up dust at 100 feet elevation, but the magic dust, because there is no atmosphere, fell quickly to the ground,and I'm assuming randomly everywhere except the landers legs. :iamwith: [/quote] It's not magic, it's physics. The dust followed a ballastic trajectory away from the lander, it did not billow and collect on the footpads the way it would on earth. [/quote]

M O O N PHOTO OF A SPECIAL KIND
LOVE THIS PHOTO COZ...
1. The Sun is so kind on the astronaut. His rays are bathing him.
2. The Astronaut's face reflects the photographer from such a long distance, so well...
