NASA probe reveals organics, ice on Mercury

CAPE CANAVERAL, FLORIDA, Dec 5: Despite searing daytime temperatures, Mercury, the planet closest to the sun, has ice and frozen organic materials inside permanently shadowed craters in its north pole, NASA scientists said on Thursday. Earth-based telescopes have been compiling evidence for ice on Mercury for 20 years, but the finding of organics was a surprise, say researchers with NASA’s MESSENGER spacecraft, the first probe to orbit Mercury.
