Why We Fight: The Nazis Strike

6:01 pm

An evening pause: For tonight, the anniversary of the Japanese sneak attack on Pearl Harbor, I think this documentary created by Frank Capra for the U.S. government in 1943 is most appropriate.

Though created to rally Americans to the war effort, the film is not propaganda. It is a remarkably accurate telling of the history leading up to Pearl Harbor in detailing how Hitler was able to gain control of almost all of Europe, through lies, force, and the weak-kneed opposition of his opponents. Only with Soviet Russia and its secret pact with Germany to divide up Poland does the film fail to tell the facts thoroughly, but here it fails by omission, not lies. In the end, however, it is accurate, because the Soviet Union’s pact, intended to bring it security from German invasion, failed. Hitler had lied once again, and the U.S.S.R. became only another victim of his greed for power.

It is worthwhile for Americans to watch it now, because the same lies and greed for power is eating away at our own country from within. Any honest open-minded viewing of this mid-20th century history cannot help but see the parallels.

I should add that Capra knew how to make movies, and he made sure this history was told in a riveting and compelling manner. You will not be bored.

The steep interior rim of Aristarchus Crater

11:30 am

Aristarchus Crater
Click for larger image.

Cool image time! The photo to the right, cropped, reduced, and sharpened to post here, is a just released image taken by Lunar Reconnaissance Orbiter, looking across the top of Aristarchus Crater on the Moon from a height of only 60 miles, with the dark surrounding plateau in the foreground contrasting sharply with the bright crater interior. For scale, the distance from the floor of the crater to the top of the rim is about 9,000 feet. The bright central peak is about 1,300 feet tall. The contrast in brightness inside and outside the crater is explained thus:

Adjacent to Aristarchus crater is the Aristarchus plateau, one of the largest volcanic centers on the Moon. Here we find one of the largest rilles [on the Moon, dubbed Vallis Schröteri], a massive pyroclastic deposit, and the source of extensive flood basalts.

These volcanic materials are considered relatively young (for the Moon) – 1.5 to 2.5 billion years. The pyroclastic deposit formed when magma was explosively ejected from the vent and broke into small droplets quenched as glass in the cold vacuum of space as they fell back to the surface. Due to their high glass content, the pyroclastic deposits are distinctly low in albedo (relatively dark), providing a dark background for the bright Aristarchus crater. Within the crater, some of these pyroclastic deposits may be visible as the darkest areas on the far wall, and glassy impact melt is moderately lower in reflectance than the bright, rocky materials exposed on areas of the crater floor and walls.

The overview map below shows both the crater and the vent from which Vallis Schröteri belched.

Today’s blacklisted American: Princeton considering blacklisting John Witherspoon, Founding Father and signer of the Declaration of Independence

1:41 pm

John Witherspoon: Target for cancellation
John Witherspoon: a target for cancellation

The modern dark age: Princeton University is now considering removing from its campus a statue of John Witherspoon, Founding Father, signer of the Declaration of Independence, and the college’s sixth president, because some students have whined about the fact that in his life he also at one time owned two slaves.

A petition, started by three graduate students in the Philosophy Department, states that the “prominent place on campus of the John Witherspoon statue is inappropriate” and calls on the university to “remove it from its pedestal in Firestone Plaza.”

The petition asks that officials replace the statue with an informational plaque that reflects both the “positive and negative aspects of Witherspoon’s legacy.”

American freedom sets a new yearly record for rocketry

11:08 pm

Liberty enlightens the world
Liberty has now also enlightened the exploration of space

Capitalism in space: In 1966, more than a half century ago, the United States government was in a desperate space race to catch up with the communist Soviet Union, which for the previous decade had been first in almost every major achievement in space, from launching the first orbital satellite, the first manned mission, the first two- and three- manned missions, and the first spacewalk.

In 1966, the NASA and the U.S. military successfully launched 70 times in their effort to catch up, a number that has remained the record for more that five decades as the most American launches in a single year.

All but one of those seventy launches were either for NASA or the military, paid for and built not for profit but for achieving the political ends of the federal government. Many of those seventy launches were also short duration technology test satellites, whose purpose once achieved ended those programs.

By the end of the 1960s, this aggressive effort had paid off, with the U.S. being the first to land humans on the Moon while matching or exceeding the Soviets in almost every major technical space challenge. The need for such an aggressive government launch program vanished.

Thus, for the next half century, the United States rarely exceeded thirty launches in a single year. This low number was further reduced by the decision in the 1970s by the federal government to shut down the entire private launch industry and require all American manned and satellite payloads to be launched on NASA’s space shuttle.

Come 2011 and the retirement of the space shuttle, all this finally changed. The federal government began a slow and painful transition in the next decade from building and launching its own rockets to buying that service from the private sector. It took awhile, but that transition finally allowed the rebirth of a new American private launch industry, led by SpaceX and its Falcon 9 rocket.

Tonight, that SpaceX Falcon 9 rocket completed the 71st launch in 2022, breaking that 1966 record by placing in orbit a commercial communications satellite. And it did it with almost two months left in the year, guaranteeing that the record has not only be broken, it will be shattered.

The first Greek star catalog discovered hidden in medieval parchment

10:04 am

Scientists have discovered part of the first Greek star catalog created by Hipparchus — thought by many to have invented the modern field of astronomy — hidden in a medieval parchment that had been reused for other puposes.

Scholars have been searching for Hipparchus’s catalogue for centuries. James Evans, a historian of astronomy at the University of Puget Sound in Tacoma, Washington, describes the find as “rare” and “remarkable”. The extract is published online this week in the Journal for the History of Astronomy. Evans says it proves that Hipparchus, often considered the greatest astronomer of ancient Greece, really did map the heavens centuries before other known attempts. It also illuminates a crucial moment in the birth of science, when astronomers shifted from simply describing the patterns they saw in the sky to measuring and predicting them.

The manuscript came from the Greek Orthodox St Catherine’s Monastery in the Sinai Peninsula, Egypt, but most of its 146 leaves, or folios, are now owned by the Museum of the Bible in Washington DC. The pages contain the Codex Climaci Rescriptus, a collection of Syriac texts written in the tenth or eleventh centuries. But the codex is a palimpsest: parchment that was scraped clean of older text by the scribe so that it could be reused.

Using modern multi-spectral imaging, the researchers were able to decipher the older text, and determined it was almost certainly written by Hipparchus and included his star measurements.

Read the whole article at the link. It is a fascinating detective story describing the origins of modern astronomy in western civilization.

Gemini/Apollo astronaut Jim McDivitt passes away at 93

8:49 am

R.I.P. Jim McDivitt, who was the commander of both the Gemini 4 and Apollo 9 missions in the 1960s, passed away on October 13, 2022 at the age of 93.

He first flew in space as commander of the Gemini IV mission in June 1965. McDivitt was joined by fellow Air Force pilot Ed White on the program’s most ambitious flight to date. During Gemini IV, White would become the first American to venture outside his spacecraft for what officially is known as an extravehicular activity (EVA) or as the world has come to know it, a spacewalk. … The mission’s four-day duration nearly doubled NASA astronauts’ previous time in space to that point, with the longest American spaceflight previously being Gordon Cooper’s 34-hour Mercury 9 mission.

McDivitt’s second spaceflight as the commander of Apollo 9 played a critical role in landing the first humans on the Moon. This was the first flight of the complete set of Apollo hardware and was the first flight of the Lunar Module. The mission launched from NASA’s Kennedy Space Center on March 3, 1969, with Commander James McDivitt, Command Module Pilot David Scott, and Lunar Module Pilot Russell Schweickart. After launch, Apollo 9 entered Earth orbit and the crew performed an engineering test of the first crewed lunar module, nicknamed “Spider,” from beginning to end. They simulated the maneuvers that would be performed during actual lunar missions. During the mission, the astronauts performed a series of flight tasks with the command and service module and the lunar module. The top priority was rendezvous and docking of the lunar module with the command and service module. The crew also configured the lunar module to support a spacewalk by McDivitt and Schweickart. On Flight Day 10, March 13, 1969, the Apollo 9 capsule re-entered Earth’s atmosphere and splashed down in the Atlantic Ocean, within three miles and in full view of the recovery ship, the USS Guadalcanal, about 341 miles north of Puerto Rico.

To me, McDivitt’s most important discovery occurred early in his Gemini mission. After launch he was tasked with an attempt to approach and rendezvous with the upper stage, shortly after deployment. He was surprised to find that his intuition about doing so was utterly wrong. Whenever he tried to close the distance by applying thrust in the direction implied by his earthbound instincts, the distance actually increased.

McDivitt’s experience showed that rendezvous and docking in orbit was not going to be simple. In fact, it took almost the entire Gemini program in 1965 and 1966 to figure it out.

McDivitt never went to the Moon, but he was like all the first generation of American astronauts, professional, careful, dedicated, and remarkably good at what he did. May he rest in peace.

Pushback: Cornell’s library lifts its blackballing of Abraham Lincoln

12:36 pm

Banned by Cornell

Our modern dark age: Faced with a storm of criticism from donors, alumni, and the public, the removal of a bust of Abraham Lincoln from the library at Cornell University, has been cancelled, and Lincoln will once again be given an honored place at the university.

The bust’s removal, along with a plaque celebrating Lincoln’s Gettysburg address (to the right), were removed in 2021 because some unnamed individual had filed a complaint. As I noted in June:

Valeri Polykov, holder of the record’s longest stay in space, passes away

10:00 am

Valeri Polykov
Valeri Polykov

Russian astronaut Valeri Polykov, who holds the record for the longest spaceflight yet of any human in history, has passed away at the age of 80.

In 1994 and 1995 Polykov spent 437 days on Russia’s space station Mir, the equivalent of fourteen months and two weeks. His thoughts at launch, as he told me personally when I interviewed him while writing Leaving Earth, were not so confident:

“What if something goes wrong?” [he explained]. “I had sacrificed so much time. The government has spent so much, more than they can afford. And I’ve learned so much for them myself, for them.

“Better I die if something went wrong,” he thought. “Better if I had a gun to shoot myself.”

Nothing went wrong however. Polykov, a doctor, had pushed for this long mission to find out if it would be possible for a person to function after a year-plus of weightlessness upon arrival on Mars. Originally planned to last 18 months, circumstances eventually shortened it to 14 months-plus. When Polykov came home in March 1995, he managed to walk a few steps on his own, shortly after being removed from the capsule. To his mind, he had proved that a person could function on their own on Mars after such a long flight.

Others disagreed. As I wrote in Leaving Earth, though he was almost normal within a week of landing,

Polykov had come back to Earth very weak. For at least those first few hours, he needed help from those around him. Any spacefarer arriving on Mars after a year in space must be prepared to face that same challenge.

Regardless, Polykov, like Brian Binnie, was one of the early giants in space exploration. His contribution must not be forgotten.

SpaceShipOne pilot Brian Binnie passes away

9:25 am

R.I.P. Brian Binnie, who piloted SpaceShipOne on its second flight that won the Ansari X-Prize back in 2004, passed away on September 15, 2022 at the age of 69.

Brian’s record flight was the second of two SpaceShipOne flights needed to win the $10 million Ansari X Prize. The prize was given for the first privately-built crewed vehicle to make a flight above 100 km (62.1 miles) twice within two weeks. Mike Melvill made the first flight for the Ansari X Prize competition five days earlier.

The success of this private spaceship proved that private enterprise could do better than government, if given the chance. It laid the groundwork for the renaissance in American rocketry we are seeing today.

His part in this history must not be forgotten.
