The latest pictures from Nasa's LCROSS mission to the moon. The impact is expected to help in the search for lunar water
Picture of the moon centering Nasa's intended impact site for LCROSS. The dark ring is the 25-arcsec field lens holder for the Altair adaptive optics system. Observers will be able to use any bright feature within this ring as a pseudo-star to guide the telescope to the impact plume. It will also help correct the image for atmospheric distortion.
