The crazy plan to explode a nuclear bomb on the Moon

From BBC.com (May 8, 2023):

The moment astronaut Neil Armstrong stepped out on to the Moon's surface in 1969 is one of the most memorable moments in history.

But what if the Moon Armstrong stepped onto was scarred by huge craters and poisoned from the effects of nuclear bombardment?

At first reading, the title of the research paper – A Study of Lunar Research Flights, Vol 1 – sounds blandly bureaucratic and peaceful. The kind of paper easy to ignore. And that was probably the point.

Glance at the cover, however, and things look a little different.

Emblazoned in the centre is a shield depicting an atom, a nuclear bomb, and a mushroom cloud – the emblem of the Air Force Special Weapons Center at Kirtland Air Force Base, New Mexico, which played a key role in the development and testing of nuclear weapons.

Down at the bottom is the author's name: L Reiffel, or Leonard Reiffel, one of America's leading nuclear physicists. He worked with Enrico Fermi, the creator of the world's first nuclear reactor who is known as the "architect of the nuclear bomb".

Project A119, as it was known, was a top-secret proposal to detonate a hydrogen bomb on the Moon. Hydrogen bombs were vastly more destructive than the atomic bomb dropped on Hiroshima in 1945, and the latest in nuclear weapon design at the time. Asked to "fast track" the project by senior officers in the Air Force, Reiffel produced many reports between May 1958 and January 1959 on the feasibility of the plan.

Incredibly, one scientist enabling this horrific scheme was future visionary Carl Sagan. In fact, the existence of the project was only discovered in the 1990s because Sagan had mentioned it on an application to an elite university.

While it might have helped to answer some rudimentary scientific questions about the Moon, Project A119's primary purpose was as a show of force. The bomb would explode on the appropriately named Terminator Line  – the border between the light and dark side of the Moon – to create a bright flash of light that anyone, but particularly anyone in the Kremlin, could see with the naked eye. The absence of an atmosphere meant there wouldn't be a mushroom cloud.

There is only one convincing explanation for proposing such a horrendous plan – and the motivation for it lies somewhere between insecurity and desperation. [read more]

Crazy indeed.
