The LCROSS results will flesh out the surprise announcements in September that three other spacecraft — India's Chandrayaan - 1 and NASA's Deep Impact and Cassini —
detected traces of water on the moon's surface by studying reflected infrared light from the sun.
Its instruments can't capture microbes or
detect life, but in a couple
of dozen passes through the plumes
of Enceladus, it has
detected various molecules associated with life:
water vapor, carbon dioxide, methane, molecular nitrogen, propane, acetylene, formaldehyde and
traces of ammonia.
