NASA is planning a mission to study the Moon’s fragile atmosphere–before it’s too late.

Oct. 23, 2009: Right now, the Moon is a ghost town. Nothing stirs. Here and there, an abandoned Apollo rover — or the dusty base of a lunar lander — linger as silent testimony to past human activity. But these days, only occasional asteroid impacts disrupt the decades-long spell of profound stillness.

Currently, the Moon’s tenuous atmosphere is relatively undisturbed. But that won’t be true for long. NASA is planning to return people to the Moon, and human activity will kick up dust, expel rocket exhaust, and release other gaseous emissions into the lunar atmosphere. Because the atmosphere is so thin, these disturbances could quickly swamp its natural composition. [...]

Using instruments on three separate spacecraft, scientists have discovered water molecules in the polar regions of the Moon.

September 24, 2009: NASA scientists have discovered water molecules in the polar regions of the Moon. Instruments aboard three separate spacecraft revealed water molecules in amounts that are greater than predicted, but still relatively small. Hydroxyl, a molecule consisting of one oxygen atom and one hydrogen atom, also was found in the lunar soil. The findings were published in Thursday’s edition of the journal Science.

“When we say ‘water on the Moon,’ we are not talking about lakes, oceans or even puddles,” explained Carle Pieters, M3’s principal investigator from Brown University, Providence, R.I. “Water on the Moon means molecules of water and hydroxyl that interact with molecules of rock and dust specifically in the top millimeters of the Moon’s surface.
