The mythbusters is simply a good video explaining what it is. I'd get into the mechanics of using lasing as a system of measuring distance but I frankly don't think you'd understand it

First point: Those shadows DON'T intersect.
Second point: Thats an edited image. Here is the full image

The reason why the shadows appear to have two different light sources is because the image is a panoramic image produced by rotating the camera and stitching several images together. Most phones have the same capability in their camera modes, and a quick search of the internet can show you what the result of these things can be when you have movement.

The reason the shadows look like they are coming from two different light sources is because the images that constitute the panorama are taken by a camera pointing at different angles for each.
Third point: I STILL HAVE LITERAL PICTURES OF THE LANDERS ON THE SURFACE OF THE PLANET. YOU CAN GO GET A GOOD TELESCOPE AND LITERALLY LOOK FOR YOURSELF. HOLY SHIT.
