ICE ON THE MOON
"Lunar ice" might sound a little strange to many people, but it didn't sound so strange to three Caltech researchers who, in 1961, suggested a few plausible arguments for its existence. The three (Kenneth Watson, Bruce C. Murray, and Harrison Brown) theorized that, since the Sun never deviates more than 1.6° from the Moon's equatorial plane, some crater floors near the lunar poles might lie in constant shadow. At 40° to 50° Kelvin, these "cold traps" could keep ice so solidly frozen that almost none of it would escape into space.
Thirty-three years later, their theory was tested for the first time.
