Max Goes to the Moon

Do you remember the kids books you read - or were read to you - when your age was just a single digit? Many of those books had a lesson as well as a tale: Little...
Sea of Dryness

The classical names for the lunar dark areas were all nautical, but all were dreadful misnomers since the Moon has always lacked seas and oceans. So today, we will examine the Sea of Dryness rather than Mare Humorum, the Sea of Moisture.
Prelude to Apollo - Ranger 8

Today is the 39th anniversary of the launch of the Ranger 8 spacecraft. The Ranger series was designed to obtain the first high resolution images of the lunar surface to help plan for Surveyor and Apollo landings.
The Image that Launched LPOD!

Lunar Picture of the Day (LPOD) was conceived in response to this photo appearing as APOD - Astronomy Picture of the Day - on December 12, 2003. There the image was shown dramatically as a negative - with white and black reversed. Here its as photographer Frank Barrett saw it in the sky on December 8, 2003.

We think of the Apollo missions as being near equatorial - and the landing sites were - but the sinusoidal orbit of the Command Modules took them as much as 25 degrees from the equator.
Happy Valentine Dome Day

Here is a lunar Valentine Day's card courtesy of KC Pau. Valentine's Day, named for a martyred Roman saint (who sent his jailer's daughter a note signed, "From your Valentine") is associated with hearts.
Copernicus in Color

Robotic spacecraft have made two major contributions to lunar imaging. From the mid-1960s thru the early 1970s, high resolution images were obtained by Lunar Orbiter and Apollo spacecraft - this is still the highest resolution coverage available for the Moon. During the 1990s, global multi-spectral coverage was acquired by Galileo, Clementine and Lunar Prospector.
Happy Birthday, Darwin!

Charles Darwin, who ranks with Newton and Einstein as one of the world's greatest scientists, was born on this date 195 years ago at Shrewsbury, England. Unlike Darwin's ideas, which remain robust, the lunar crater Darwin has seen better days.
I Drew a Lunar Map So I Get to Add Names!
10.02.2004 | Лунное фото дня
Somewhere, a decade or so ago, I picked up a single page from an old Pacific Discovery magazine that contained this map. Its obviously a hand drawn one, with a lot of effort spent depicting hundreds of craters with many slightly jiggly lines representing the maria.
Lunar Pyroclastic Deposits

Lunar volcanism is best represented by the massive lava flow piles - or maria - filling impact basins. But the Moon also had other styles of volcanic activity including explosive or pyroclastic eruptions. Pyroclastic is the two dollar (2 Euro?) word for fragmental rocks thrown out of erupting volcanoes.
