The 97 km wide crater Arzachel is often overlooked, being near the superstars of Alphonsus and Ptolemaeus. But Steve Keene became fascinated with Arzachel early in March and, despite average seeing, acquired this fine image.

Lunar Topographic Orthophotomosaic. That mouthful explains the widespread use of the abbreviation LTO for the best topo images ever made for the Moon. Derived from stereo images taken from Apollo orbiting command modules, more than 250 LTOs were produced covering much of the landscape under the flight paths of Apollo 15, 16 and 17.

Volcanism on the Moon is completely dominated by mare basalts, mostly in the form of vast sheets of lava flows that create the maria. Sitting on top of mare lavas in some places are 5-20 km wide blisters or domes, some with summit pits.

Thirty-nine years ago today the Ranger 9 spacecraft crashed into the north-east floor of Alphonsus crater, having successfully taken 5,814 pictures during the previous 19 minutes. Rangers 7 and 8 had provided high resolution views of possible landing sites on mare surfaces, freeing Ranger 9 to explore a geologically more interesting site.

Its impossible to take a single image of the Moon that shows topography across the entire Earth-facing side. Pablo Lonnie Pacheco of Monterrey, Mexico has responded to this impossibility with the most spectacular piece of image processing I have ever seen.

Is it a globe if it has 20 sides? Not really, but its close enough to be a useful 3-D rendition of the Moon. Go to Calvin Hamilton's web site to download a larger version of this image, and then with, scissors, glue or two-side tape, fold yourself a Moon.
An Unusual View of a Lunar Limb

As the Galileo spacecraft swung by the Earth-Moon system to get a gravitational boost for its long trip to Jupiter, it imaged the Moon. Most attention was focused on the Full Moon view of Mare Orientale, visible at top right.
