LRO
An analysis of data detected by the Lunar Reconnaissance Orbiter of the LCROSS impact last October finds the presence of carbon monoxide in Cabeus Crater in higher concentrations than the approximately 155 kg of water ice and water vapour, more than initially estimated, in addition to two hydroxyl flavours and smaller quantities of hydrogen sulfide, carbon dioxide, sulfur dioxide, methane, formaldehyde, mercury, magnesium, calcium, sodium, hydrogen gas, and possibly ammonia, ethylene and silver.
