Image of the Week - Moon Craters in Arizona

Before landing on the surface of the moon in 1969, astronauts Neil Armstrong and Buzz Aldrin needed a training ground that matched their destination's cratered surface.

In the U.S., that turned out to be northern Arizona. Starting in 1967, the U.S. Geological Survey used hundreds of pounds of dynamite to blast holes into the surface of ancient lava fields south of

Previous Evidence of Water on Mars Now Identified as Grainflows

This HiRISE image cutout shows Recurring Slope Lineae in Tivat crater on Mars in enhanced color. The narrow, dark flows descend downhill (towards the upper left). Analysis shows that the flows all end at approximately the same slope, which is similar to the angle of repose for sand.
Dark features previously proposed as evidence for significant liquid water flowing on

New USGS Maps of Mars Reveal Ancient Oases

Flyover of the southeast Ceti Mensa map. Distinct groups of rock layers, called geologic units, are shaded in different colors, with dark browns representing the oldest rocks and green representing the youngest rocks. All of these rocks formed as wind-blown sand that became trapped in shallow, ephemeral lakes, similar to the wet playas of the desert southwest US. The
