Quite a remarkable map, table, and diagram from a 1971 report on launch-on-warning, showing the implications of Soviet submarine launched ballistic missiles (SLBM) on detection, reaction, deliberation, and response time. All numbers are in SECONDS, which is what I find the most wild about it.
Map of the USA labeled "Soviet SLBM [Submarine Launched Ballistic Missile] Time of Flight to SAC [Strategic Air Command] Targets." Shows both "nominal" and "depressed" trajectories. Absolute best (north central USA) is between 580 and 850 seconds (9.6 – 14 min). Absolute worst (everywhere else) is between 320 and 650 seconds (5.3 – 10.8 min). The variations are based on where they assume the subs are launching from. Table: "Early Warning System Performance." Shows four different systems (BMEWS, OTHF, SLBM Net, and a not-yet-operational in 1971 Boost-Phase Detection Satellite) that indicates the time of detection after launch (varies between 55 and 150 seconds; BMEWS cannot detect launches as it is only over-the-horizon radar), the time that the US command and control system would be alerted after launch (ranges from 85 seconds for the newest system to 900 seconds for BMEWs), the probably of detection of a single launch (BMEWS is 99%, SLBM Net is 50%, none of the others have probabilities), probably of detection for a mass launch (all around 100%), and their false alarm rate (BMEWS has 1 per 7 years, OTHF is 1 per 6 months, the others are unknown). Diagram: "National Command-Warning to Response Cycle." Shows the consequences of a launch detection all the way through the US nuclear infrastructure, with "delay times" in seconds. Will be discussed in the next post in this thread.

This is a photograph of the edge of one of Saturn's rings, looking down from above. Those spiky dark shapes are shadows. Shadows of giant towers of ice and dust grains clumped together that rise up to three *kilometres* above the 10-m thick rings.
A series of bands cross the image from left to right, brighter at the bottom and darkening towards the top. A band of empty space is at the top of the image. About a quarter down from the top is a complex pattern of jagged, spiky shadows cast onto the rings. The icy towers casting the shadows are seen here at a highly oblique angle.

There is a bit of a story to how we obtained this 1961 report on nuclear weapons in space (and another from 1963 that we will write about later). The existence of these nukes in space studies has been known for decades, but almost all of them are classified. I FOIA'd several of them a decade ago.

This is my favourite Borges story.
The Witness by Borges and translated by ANTHONY KERRIGAN

In a stable lying almost in the shadow of the new stone church, a man with
gray eyes and a gray beard, stretched on the ground amidst the animal
odors, meekly seeks death like someone seeking sleep. The day, faithful to
vast secret laws, continuously displaces and confounds the shadows in the
wretched stable. Outside stretch the tilled fields, a deep ditch filled up with
dead leaves, and the tracks of a wolf in the black mud where the woods
begin. The man sleeps and dreams, forgotten. The bells calling to prayer
awake him. In the kingdoms of England, the sound of the bells is already
one of the customs of the afternoon, but the man, while still a boy, had
seen the face of Woden, had seen holy dread and exultation, had seen the
rude wooden idol weighed down with Roman coins and heavy vestments,
seen the sacrifice of horses, dogs, and prisoners. Before dawn he would be
dead and with him would die, never to return, the last firsthand images of
the pagan rites. The world would be poorer when this Saxon was no more.
We may well be astonished by space-filling acts which come to an end
when someone dies, and yet something, or an infinite number of things,
die in each death—unless there is a universal memory, as the theosophists
have conjectured. There was a day in time when the last eyes to see Christ
were closed forever. The battle of Junín and the love of Helen died with
the death of some one man. What will die with me when I die? What
pathetic or frail form will the world lose? Perhaps the voice of Macedonio
Fernandez, the image of a horse in the vacant space at Serrano and
Charcas, a bar of sulfur in the drawer of a mahogany desk?

Four laser beams project out from the VLT's UT4.  Some 90 km up in the atmosphere, they excite atoms of sodium, creating artificial stars for the telescope’s adaptive optics systems. But why four lasers and not just one? Find out: www.eso.org/public/images/potw1618a 🔭 #flashback
