Most Detailed Lunar Map Suggests Little Water Inside Moon

An international team of researchers has created the most detailed map of the Moon yet, using the laser altimeter (LALT) instrument on board the Japanese Selenological and Engineering Explorer satellite.

ScienceDaily (Feb. 23, 2009) — The most detailed map of the Moon ever created has revealed never-before-seen craters at the lunar poles.

The map is also revealing secrets about the Moon's interior -- and hinting about Mars's interior as well.

C.K. Shum, professor of earth sciences at Ohio State University, is part of the international research team that published the map in the February 13 issue of the journal Science.

"The surface can tell us a lot about what's happening inside the Moon, but until now mapping has been very limited," Shum said. "For instance, with this new high-resolution map, we can confirm that there is very little water on the Moon today, even deep in the interior. And we can use that information to think about water on other planets, including Mars."
