For Women's History Month - a thing I wrote.

My goal was to highlight interesting lunar features imaged by LRO that were named for lesser-known scientists. Blagg Crater, named for Mary Adela Blagg, is located in Sinus Medii.

I requested that the crater be reimaged.

Excerpts from a NASA public info publication in my collection. This one, from December 1976, is a special issue of the VIKING PROJECT BULLETIN, a newsletter NASA mailed out free upon request.

A nice relic of pre-Internet days.

I post one of these in its entirety on my Patreon every Sunday.

For your Saturday enjoyment, here is Gene Shoemaker leaning in front he left and Kuiper on the right looking at the first Ranger images of the moon at JPL.

The near & far sides of the Moon, as seen by NASA's LRO spacecraft.

China's Chang'e-6 lunar lander may have solved one of the great Moon mysteries: Why does its far side look totally different than the side that faces us?

A huge impact 4.3 billion years ago partially melted the Moon's mantle & made it lopsided, according to a new study. 🧪🔭

Sixty years ago today, on February 3, 1966, Luna-9 was the first spacecraft to survive landing on the surface of another world. It is wild to think that the Space Age is so young that there are still millions alive now who were adults when this happened.

The First Lunar Lander and the Great Moon Dust Debate - JSTOR Daily In 1966, the Soviet Union’s Luna 9 became the first spacecraft to soft-land on the Moon, helping to resolve questions about the nature of the lunar surface.

60 years ago, Luna 9 gave us our very first images from the lunar surface. The pictures dropped into a debate about the nature of the Moon, and scientists rushed to interpret them.

The Hidden Aesthetics of Early Astrophotography - JSTOR Daily Behind the transformative star photographs of the 1880s lay a complex collaboration between astronomers and engravers.

Astronomers in the 19th c. hoped that photography would help mechanize observation, but judgement still crept into their processes. Engraving and printing astronomical images required collaboration--and aesthetic choices.

Spectacle on Other Worlds The first spacecraft from Earth to touch another world carried no people, but it did carry a unique sort of flag. Early on the morning of September 14, 1959, the Soviet space probe Luna 2 impacted …

Luna 2 and Mariner 4 both carried nationalistic symbols. What do they tell us about the motivations of early space explorers?

The Radioactive Reindeer Problem - JSTOR Daily Cold War nuclear testing left troubling levels of Cesium-137 in caribou, prompting years of research into Arctic fallout and its risks to human health.

Scientists studying reindeer/caribou early in the Cold War made a startling discovery. It led to a major public health investigation, turning Canada and the Arctic into nuclear spaces.

How Lunar Photography Brought the Heavens Down to Earth (Gift Article) No explorers ever traveled farther from home than the Apollo astronauts. As artists, they’re still underrated.

Whether you like science or art or history or space travel, I promise this will be the best thing you read all week.

The Erie Canal at 200 - JSTOR Daily Finished in October 1825, the Erie Canal connected increasingly specialized regions, altering the economic landscape of the northeast United States.

The Erie Canal was completed 200 years ago today. It was a major achievement for the early US, and for New York in particular. But the canal meant different things to different people, and over time, its significance evolved.

“Mad About Geology”: Charles Darwin’s Origin Story - JSTOR Daily At university and in the field, Darwin trained his scientific thinking as would a geologist, seeking causal explanations for observed natural phenomena.

Darwin's geological training shaped his scientific identity. He took classes from professors on opposite sides of a major geological debate. One was dull, the other exciting-but he learned a lot from both, and from field excursions in Wales.

When Charles Darwin joined the crew of the Beagle in 1832, one of their first stops was the island of St. Jago in Cape Verde. There, he confronted one of his first major scientific puzzles. https://bit.ly/3WjDAwl

The Art of Deforestation - JSTOR Daily Landscape paintings show how quickly American forests changed in the early nineteenth century—and the mixed feelings people had about that change.

Painters of the Hudson River School understood what was happening to North American forests in the nineteenth century, and they didn’t like it. https://bit.ly/42tM7Ag

Arthur C. Clarke’s Scuba Adventures and Ocean Frontiers - JSTOR Daily Clarke’s interest in oceanic exploration in the 1950s was, like his undersea fiction, often neglected by an audience focused on the race for outer space.
