New Color in Old Pictures
31.05.2005 | Lunnoe foto dnya
As the Apollo astronauts orbited the Moon they shot many photographs using various cameras including large format Hasselblads loaded with both black & white and color film. The color film provides little real color because the Moon is largely a world of grays.
Hundreds of Domes
30.05.2005 | Lunnoe foto dnya
In terrestrial volcanology the word dome most commonly refers to a silica-rich, steep-sided volcanic hill. But typical lunar domes, such as Kies Pi, are most like terrestrial small shield volcanoes which are made of silica-poor basalts and have very gentle slopes.
A Shallow Sea of Lava

Mare Fecunditatis lavas are assumed to fill an impact basin because that is the case for nearly every other roughly circular pile of lava on the Moon. But there is little evidence for the basin, except some curved ridges that might represent an inner ring.
Down the Rille

Even when we have a great telescopic view of the Moon we typically see it as a distant world, without a sense of dimensionality. But the oblique Apollo images give us a feel for the real three-dimensional Moon. And the high resolution improves our understanding of the surface geology.
Is It Love or a Sinus Infection?

I thought I knew the Moon until I saw this image. The right side, showing Cauchy and nearby fault, rille and domes is familiar, of course. The left side reveals features in the Bay of Love (Sinus Amoris) that I never knew existed.
A New Kind of DHC
26.05.2005 | Lunnoe foto dnya
Optical dark halo craters (DHC) are typically small impact craters that excavated into buried mare material, or they are volcanoes that ejected ash. Radar studies have resulted in the discovery of a new type of DHC: radar dark halo craters (RDHC). This radar image of Petavius and surrounding area beautifully illustrates a RDHC.
An IR Strip Across a Kipuka

What can you do when the Moon is hidden by clouds? Explore it with Clementine images! This image shows the kipuka (old surface surrounded by younger lavas) north of Menelaus, illustrated in LPOD on May 14.
Grand Central Station

Palus Epidemiarum is a patch of mare occupying the southern armpit of Humorum and Nubium. This is a highly concentrated area of rilles that have little obvious relation to nearby basins. K.C.s magnificent image...
Snaky Rivers
23.05.2005 | Lunnoe foto dnya
The vertical strips immediately tell the historian of lunar imaging that this is a Lunar Orbiter photo. But the feature itself is difficult to identify because it is small - each vertical framelet is only about 550 m wide.
Domeland

Selenographers are confident that lunar domes are small shield volcanoes, and that swells are perhaps a type of shallow laccolith (intrusion of magma just under the surface). But what we dont understand, except in a most rudimentary way, is why domes occur where they do.
