40 Years Since Impact
31.07.2004 | Лунное фото дня
Forty years ago today, the US lunar exploration program finally found success. After a series of embarassing failures, the rocket, the navigation and the cameras all worked, and Ranger 7 radioed back to Earth about 4000 images of ever increasing resolution as it approached and finally slammed into the Moon.
Obliquely Viewed Fault

One of the most famous features on the Moon - certainly as judged by the number of image submissions to LPOD - is the Straight Wall. Until chancing upon this image in the online Apollo Image Atlas at the Lunar & Planetary Institute, I though that the Wall had not been photographed during the Apollo program.
EAW & GPK

Ewen Whitaker and Gerard Kuiper (in tie) looking at a photo of the landing site for Ranger 6, as the spacecraft sped towards the Moon on Feb 1, 1964. Ranger 6 hit the Moon the next day very near its target in western Mare Tranquilitatis. But as the solemn faces foretold, no photos were taken.
Cognitum Kipuka

Kipuka is a Hawaiian word for an island. In volcanology it is an island of older land surrounded by a younger lava flow. In the middle of Mare Cognitum - the Known Sea (known because it is where Ranger 7 acquired the first high resolution images of the Moon) - are a number of kipukas.
What is a Dome?
27.07.2004 | Лунное фото дня
I know what a lunar dome is. Its a perfectly symmetrical mare rise, low-sloped and preferably topped with a summit pit. The Hortensius domes and the dome near Kies are the ideals of lunar domes. But I am broad minded, so I also call the steeper-sided, rougher textured, pitless low hills near Arago domes too.
Two Satellites

I was taking images of the Moon with my Celestron 8" SCT, a 25mm plossl, and my Canon G1 digital camera, held afocally in front of the eyepiece by hand. Just playing around, not intending to image anything of importance.
Pre-History of the Triesnecker Area

The Triesnecker area is a magnet for observers - not because of the 26 km wide fresh crater, but for the nexus of mostly linear, thin rilles east and north of the crater. This...
An Excess of Craters
24.07.2004 | Лунное фото дня
I worked my way through college by measuring lunar craters for the System of Lunar Craters catalog published by the Lunar & Planetary Lab in the early 1960s. I am glad that this image of the middle of the lunar farside was not available then - it is a crater counter's nightmare!
Sun, Moon and Stars

How often can you see an image of the Moon, Sun, Venus (pink dot) and stars all in one frame? This dramatic view from a decade ago was taken by the Clementine lunar orbiter's Startracker camera.
Huge Fractures

These images are remarkable in showing the tectonic structure southeast of Mare Nectaris. And because Bob Botts took images on successive nights of the waning Moon we can see the same area illuminated and then deeply shadowed. The area SE of Nectaris is well known for its strong and conspicuous radial basin structures.
