This article discusses the possibility that water might exist on the Moon. Topics include some uses for water in space (other than drinking), where the water might be found, and the idea that it may have been 'delivered' to the Moon by comets, which are largely made of ice. Full description.

NASA Investigators working with Mars Odyssey data may have discovered remnants of snow packs that have created a system of gullies in crater walls and other, more unusual places such as ridge crests, sand dunes, and hilltops. Readers of this journal article can learn about the snow packs and their potential to collect and shelter water beneath themselves, possibly providing a favorable environment ... Full description.

This article from Astrobiology Magazine reports on the discovery of water in "cold" regions of space. Using data from the European Space Agency's Infrared Space Observatory, astronomers have determined that water is abundant in these cold, or quiescent regions of space where there are no stars, and that the majority of it occurs as ice with a small amount of water vapor. It is thought that these cold ... Full description.
