Frame from a short video is of a post laser ablation crater using a nanosecond 193nm laser ablation system of a glass slide using a 210 micron spot diameter and 250 shots. It shows a flat bottom crater indicative of a homogenized laser beam, though the measured diameter of the crater appears to be 25 microns smaller the diameter set. The 3D crater image

Interview with USGS scientist Dr. Roger Clark about his Sept. 24 Science article that suggests water exists on the moon. Imaging spectroscopy led Clark and others to this discovery which opens the possibilities into further moon exploration.
