The once and future Moon
Paul Spudis provides a very detailed analysis of the recently released LCROSS lunar results. Key quote:
The Near-IR spectrometers on the LCROSS shepherding satellite detected abundant water (H2O) but also hydrogen sulfide (H2S), ammonia (NH3), methanol (CH3OH), methane (CH4), ethylene (C2H4) and sulfur dioxide (SO2). The uv-vis spectrometer found carbon dioxide (CO2), sodium, silver, and cyanide (CN). Aboard the distant LRO spacecraft, the ultraviolet LAMP imager detected hydrogen (H2), nitrogen, carbon monoxide (CO), sodium, mercury, zinc, gold (!), and calcium. But water, present in quantities between 5 and 10 weight percent, is the most abundant volatile substance present.
