LCROSS's first launch opportunity is June 18. We went to bed last night thinking Shuttle would launch, and if they didn't, we'd be scheduled for June 19. Surprise, surprise! Our team mobilized today to get everything ready for our first shot at the moon. This, and one of my readers suggested a great idea - to have people look for the gas plume vented by our Centaur upper stage before it cedes control to LCROSS.
