Vaporum: Crater or Basin?
21.08.2004 | Лунное фото дня
Have you noticed the circular patch of mare that cuts into the back slope of the Apennine mountains? With the name Mare Vaporum you may think there is little there but vaporous nothingness, but look more closely.
Humor More My Fault

Geologists love to find boundaries because they demonstrate the relation between different units. At a boundary you can usually identify two different rock types or geologic processes or ages. Some boundaries feather into each other and others are sharp and distinct.
A New Dome?

The northeast region of the Moon, beyond Serenitatis and north of Crisium is a region of discomfort. Its a wild place with the confusion of the Taurus Mountains and similar unstructured but unnamed chaos between Atlas and Cleomedes.
Last Rocks from the Moon

On August 18, 1976 - 28 years ago today - the Luna 24 spacecraft landed on the Moon in southeastern Mare Crisium. Following two previous failures (Oct 1974 and Oct 1975) Luna 24 successfully landed at 12.25 degrees N, 62.2 degrees E, just a few hundred meters from the damaged Luna 21 spacecraft.
Rima Weird

As a good generalization, sinuous rilles occur on the maria because the rilles are distributary channels for flowing lava. There are some exceptions, including the four around Plato, and here is another one.
Megadome

Is Rumker the Moon's biggest dome? How about the Aristarchus Plateau? What about the Gardner Megadome, a structure I named in The Modern Moon, and shown in the overview image above (circled on mouseover)? In fact, are any of these landforms domes, other than in a strict topographic sense?
Flammarion x 2
15.08.2004 | Лунное фото дня
This has been a great couple of weeks for lunar photography, with many skilled imagers acquiring wonderful pictures nearly every night of the lunation. Here is a recent pair of Flammarion, an often overlooked and slightly battered crater north of Ptolemaeus. Have you ever knowingly observed Flammarion?
A Rip Across Tranquillity
14.08.2004 | Лунное фото дня
WOW! This is a wonderfully provocative image because of the features it shows and the others it suggests! The Cauchy area is remarkable for its near parallel fault scarp and rille, and for its two or three big domes. But even more delicate features appear with very low lighting.
Double Valentine

Perhaps we need a double Valentine to ward off a Friday the 13th! The image on the left might seem familiar to long time visitors - it was LPOD in February, and was taken by KC Pau. The lower sun image on the right was acquired recently by Jim Phillips.
Ptolemy's Strange Floor

The floor of Ptolemaeus is famous for its shallow depressions called saucers. But this extremely low sun and high resolution view shows that the floor has a lot more features than have been generally reported.
