The search for Mars Polar Lander

12:08 pm

A small section where Polar Lander might have crashed

In December 1999 the U.S. lander Mars Polar Lander was to set down near the southern polar cap of Mars. After an almost routine eleven month journey to Mars, all efforts to contact the spacecraft after its landing failed. A NASA review eventually concluded that the spacecraft had prematurely shut down its landing engines while the spacecraft was still far above the surface, and had therefore crashed to the ground.

Since then there have been extensive efforts to locate the lander’s remains on the surface, all to no avail. Though Mars Global Surveyor, in orbit at the time, tried to find it, its resolution was not sufficient. In recent years Mars Reconnaissance Orbiter (MRO) has taken several dozen high resolution images of the estimated landing area, two of the most recent were included in the August 2018 image release. The image on the right is a cropped section of one of those images, illustrating the difficulty of the search. (If you click on the image you can explore the full version.) The other image is quite similar.

As the southern polar cap shrinks and grows seasonally, it produces endless numbers of black spots from the release of underground dust as the carbon dioxide dry ice sublimates into gas. Moreover, the growth and retreat of the dry ice cap changes the landscape, periodically covering any remains of the rover as well as quickly removing many of the ground disturbances that the crash might have caused. In the almost two decades since the lander’s crash landing, about ten Martian years have passed, meaning that cap has melted and frozen ten times over this region in that time.

Images taken by MRO of Mars Polar Lander landing area

The image on the right shows the footprint of all the images that MRO has so far taken of the Mars Polar Lander landing area. If you are ambitious and want to get your name in the news, all you have to do is spend some time combing through those images and find the lander there. Every one of these images is available for public download at full resolution. Go to HiRise image archive, hover your mouse over latitude 77 degrees south, longitude 166 degrees east, and click several times to zoom in. You then change the selector icon at the top from “+” to “the arrow”. When next you click on any portion of that footprint it will show you a bunch of the images taken, all of which you can now download and inspect.

If you are successful and find the lander, please let me know. It would be nice to make that announcement here on Behind the Black.

The Polls Are Crazy

6:26 pm

Link here. The author does what I had been thinking of doing, of listing a bunch of recent polls that result in completely contradictory conclusions about where the November 2018 elections might be headed.

So how can we make sense of all of this? We can’t. Voters increasingly see the Democrats as extreme and out of the mainstream–no surprise there, since they are. Many Democrats want the U.S. to follow in Venezuela’s footsteps, but don’t want to admit it. Meanwhile most voters, while sensing this, also want the Democrats to control Congress.

My guess is that the polls are missing major currents that will become clear, as in 2016, only after the votes are counted. What those currents will turn out to be, no one really knows.

I can probably provide one possible explanation for why the polls “are missing major currents.” For the past year I have been routinely hanging up on robot-polls. I found them to generally be insulting, useless, and stupid. Then, about three months ago I got a live person conducting a poll, and decided to participate. It was centered on the Republican primary for Congress in my district, something I had not yet delved into.

I soon found it was a push poll, designed to make two candidates look terrible while a third God’s gift to heaven. This was as insulting and annoying as the robot-polls. Worse, it took about ten minutes of increasingly obvious questions to find this out, a real waste of my time.

Since then, I have been refusing to participate in any polls, live or robot. I have better things to do with my time. And I suspect I am not alone in this decision. The number of polls that have been calling our home sometimes rose to ten a day, most of which were fake push polls or stupid in their content. I can imagine a lot of people have responded as I have, which of course makes all the polls increasingly unreliable.

One more thing revealed by the polls at the link, though this really isn’t a surprise: The favorable opinion of socialism held by the young and Democrats is based on some astonishing and apparent ignorance:

Still, one wonders: how can any sentient being favor an ideology that turns a prosperous country into Cuba, Albania, the U.S.S.R., North Korea or Venezuela? The only explanation is invincible ignorance. Rasmussen sheds light on the nature of that ignorance: “Democrats are less likely to know what socialism is compared to other voters but have a much more favorable opinion of it.”

Rasmussen applied a simple criterion for socialism: “Twenty-nine percent (29%) of Democrats…incorrectly believe the individual has more power than the government in a socialist system, a view held by just 12% of Republicans and seventeen percent (17%) of unaffiliated voters. Eighty percent (80%) of Republicans correctly say the government has more power in a socialist system, and 54% of Democrats and 67% of unaffiliateds agree.”

Ignorance about socialism is especially prevalent among the young: “Those under 40 have a much more favorable opinion of socialism than their elders do and are the strongest supporters of Democrats becoming a national socialist party. But younger voters are also the most likely to believe the individual has more power under a socialist system.

I read this and fear deeply for the future. The coming dark age is only a short journey around the corner.

Is the entrance to space 80 kilometers up instead of 100?

9:56 am

A new analysis by one scientist suggests that the official line when one enters space should be lowered from 100 kilometers to 80 kilometers.

A close look shows that the traditional definition flies in the face of evidence, says Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. As a hobby, McDowell compiles an influential, detailed record of rocket launches online.

…Most people continued to use 100 kilometers as a boundary, including the World Air Sports Federation (FAI) in Lausanne, Switzerland, the keeper of outer space records. Although definitions are always points of contention in science, it seemed worthwhile to McDowell to dig deeper, knowing such companies as Virgin Galactic and Blue Origin could soon be offering tourism flights to this boundary realm.

He started with data: namely, public records of satellite telemetry he had downloaded from the North American Aerospace Defense Command about the orbits of 43,000 satellites. Most didn’t matter for his project—they orbited far too high above the edge of outer space. But at least 50 had orbits that occasionally operated below 100 kilometers, such as the Soviet Elektron-4 satellite, which made 10 spins at 85 kilometers or below before disintegrating into the atmosphere in 1997. “Are you going to say [these satellites are] in space and then not in space every 2 hours?” he asked. “That doesn’t seem very helpful.” Below 80 kilometers, the story changes: It is highly unlikely a satellite will make another orbit, as thickening atmosphere sends it to a fiery end.

Considering that the Air Force has for many years used 50 miles, which is about the same as 80 kilometers, all McDowell is doing is accepting the American definition rather than an international one. It is also amusing how his actions help Virgin Galactic, since there have been rumors for years that their SpaceShipTwo design was never going to go as high as 100 kilometers, and was going to use the Air Force 50 mile definition to say their passengers reached space.

Putting Virgin Galactic aside, however, the Air Force definition has always made more sense. As McDowell notes, it better describes the dividing line between orbital space and the atmosphere where no satellite can remain in orbit.

The first American dogs were different, and arrived a very long time ago

9:23 am

New genetic research using buried dogs found at two sites in Illinois suggests that the first American dogs came over from Siberia over 16,000 years ago, and were genetically distinct from European dogs.

In the 1960s and 1970s, archaeologists excavated two sites in western Illinois, where ancient hunter-gatherers collected shellfish from a nearby river and stalked deer in surrounding forests. These people also appear to have buried their dogs: One was found at a site known as Stilwell II, and four at a site called Koster, curled up in individual gravelike pits.

Radiocarbon analysis of the bones reveals that they are around 10,000 years old, making these canines the oldest dogs known in the Americas, researchers report on the bioRxiv server. It also makes these the oldest solo dog burials anywhere in the world. The Stilwell II dog was about the size of an English setter, whereas the Koster dogs were smaller and slenderer, says the study’s lead author, Angela Perri, a zooarchaeologist at Durham University in the United Kingdom. “It wouldn’t be surprising if they were all used as hunting dogs.” But where did they come from in the first place?

A second study, published today in Science, may have the answer. A large, international team of researchers sequenced DNA from the mitochondria, or cellular power plants, of 71 North American and Siberian dog bones—including from one of the Koster dogs—dated from about 10,000 to 1000 years ago. When they compared this material, which is passed down only by the mother, to that of 145 modern and ancient dogs, they discovered that the ancient American dogs have a genetic signature not found in any other canines.

There is much uncertainty still about the dates, but not about the genetics. The dogs were larger, resembles wolves, and even howled instead of barked. They were wiped out after the arrival of the Europeans in American, probably because of disease.

Failed Soviet-era Venus probe to crash to Earth between 2023-2025

12:59 pm

A failed Soviet-era probe to Venus that never left Earth orbit is now predicted to crash to Earth sometime between 2023-2025.

The Kosmos 482 interplanetary station, which was unsuccessfully sent towards Venus in 1972 by the USSR, may crash land on Earth between 2023 and 2025, astronomer and cosmonautics historian Pavel Shubin told Sputnik. He couldn’t pinpoint the exact location of the future crash site, but noted that it would be between 52 degrees north and 52 degree south latitude.

The astronomer has studied the data on Kosmos 482 orbit as well as its deterioration and detected that it started to degrade faster due to it getting closer to Earth and experiencing increased gravitational pull.

He also expressed confidence that the station would successfully reach the surface since it was adapted for entering the much harsher atmosphere of Venus so is able to endure stress of 300g and 100 atmospheres. The astronomer is anxious to study the station after it lands in order to analyze how prolonged exposure to open space affected its materials.

It is not likely that this probe will land anywhere where it can be recovered, as most of the Earth is ocean. However, the scientist’s hopes are not unreasonable, as it is always worthwhile for future engineering designs to study how the environment of space effects materials over long periods of time.

AT&T: How to Use the Dial Phone

6:01 pm

An evening pause: I would not be surprised if some of the younger readers of Behind the Black would need the instructions in this silent film in order to properly use a rotary phone.

Introducing any new technology requires instruction. This was strange stuff to homeowners in 1927, but a great improvement over party line phones that required an operator to do the dialing. And this was cutting edge then, and a symbol of the future.

The Declaration of Independence

12:49 pm

Link here. I think today it is worthwhile to read the whole thing, even though it is the first sentence in the paragraph below that is most often quoted. The following sentences are just as important, though less frequently quoted.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn that mankind are more disposed to suffer, while evils are sufferable than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.

All governments tend toward oppression. Power-hungry individuals always act to use the power government wields for their own corrupt purposes. Thus, Jefferson was correct above when he said that, when those abuses become bad enough, it is the right of the citizen “to throw off such government.”

We sadly might be approaching a time in the U.S. where such action will once again be necessary.

Buzz Aldrin sues his own family

10:04 am

Buzz Aldrin has sued his own family in response to disagreements about the management of his financial affairs.

This is one of those stories that is hard to interpret or analyze. The facts as presented by either side could justify their actions, and thus it is hard to say what really caused the rift. It will require a full court case to settle it.

Regardless, this does seem to be the kind of craziness that often follows Buzz Aldrin wherever he goes.

Walt Disney’s MultiPlane Camera

6:01 pm

An evening pause: This was filmed in 1957, and was almost certainly made to be shown as part of Disney’s weekly television show series for kids that began in 1954 and was one of television’s most popular shows in the 1960s. It describes one of the most important technical developments in animation, developed by Disney, until the arrival of computers.

To repeat: This was made for kids, yet it is thoughtful, entertaining, educational, and quite detailed in the information being conveyed. It treats its young audience with great respect and dignity.

I generally do not watch children’s shows today, but the few that I have seen have generally been quite shallow, overwrought, and would have insulted me, when I was a child. I don’t know if today’s kids would react the same today, because when I was a child Disney’s show was somewhat typical. I expected to be treated with respect. Today’s kids might not have that expectation.

The history of the second amendment

10:31 pm

Link here. Anyone who wishes to avoid being willfully ignorant about the reasons and background to the second amendment and presently feels lacking in knowledge will find this essay immensely clarifying. Bottom line:

Again, both sides [in the debate over the ratification of the Constitution] not only agreed that the people had a right to be armed, both sides assumed the existence of an armed population as an essential element to preserving liberty. The framers quite clearly had adopted James Harrington’s political theory that the measure of liberty attained and retained was a direct function of an armed citizenry’s ability to claim and hold those rights from domestic and foreign enemies.

And from the conclusion:

English history made two things clear to the American revolutionaries: force of arms was the only effective check on government, and standing armies threatened liberty. Recognition of these premises meant that the force of arms necessary to check government had to be placed in the hands of citizens. The English theorists Blackstone and Harrington advocated these tenants. Because the public purpose of the right to keep arms was to check government, the right necessarily belonged to the individual and, as a matter of theory, was thought to be absolute in that it could not be abrogated by the prevailing rulers.

These views were adopted by the framers, both Federalists and Antifederalists. Neither group trusted government. Both believed the greatest danger to the new republic was tyrannical government and that the ultimate check on tyranny was an armed population. It is beyond dispute that the second amendment right was to serve the same public purpose as advocated by the English theorists. The check on all government, not simply the federal government, was the armed population, the militia. Government would not be accorded the power to create a select militia since such a body would become the government’s instrument. The whole of the population would comprise the militia. As the constitutional debates prove, the framers recognized that the common public purpose of preserving freedom would be served by protecting each individual’s right to arms, thus empowering the people to resist tyranny and preserve the republic. The intent was not to create a right for other governments, the individual states; it was to preserve the people’s right to a free state, just as it says. [emphasis in original]

Read it all. It puts this issue of gun rights into historical and accurate context. That there are Americans today that do not know these facts, and refuse to learn them, speaks very poorly of them. It also suggests their goal is not the prevention of violence but the oppression of others. Such a goal is directly threatened by these historical facts — describing the British and American search for liberty and freedom — which is why they do not wish them known, and often do whatever they can to suppress them.

Woman sues NASA to keep possession of moon dust

4:24 pm

A Tennessee woman is proactively suing NASA in order to guarantee the agency will not try to steal a vial of moon dust that Neil Armstrong gave to her in the early 1970s.

Murray Cicco received the small glass vial full of gray moon dust in the early 1970s. The vial came with a note: “To Laura Ann Murray — Best of luck — Neil Armstron Apollo 11.” …Armstrong’s note and signature have been verified and testing has confirmed the contents in the vial he gifted her do include dust from the moon.

Decades after receiving the glass vial of moon dust, Murray Cicco is moving forward with her federal court case in Wichita, even though she lives in Tennessee. The reason for filing the case in Kansas goes back to a previous case in 2016 where a U.S. District Court judge in Wichita ruled in favor of a collector who bought a bag containing moon dust that was mistakenly placed in an online government auction. In that case, the bag was then sold at auction last year for $1.8 million.

While NASA hasn’t demanded Murray Cicco give up the vial of moon dust, Murray Cicco’s attorney has requested a jury trial in Wichita to stay ahead. “There is no law against private persons owning lunar material. Lunar material is not contraband. It is not illegal to own or possess,” the court document detailing the case says. “Therefore, she requests judgment declaring her the rightful and legal owner of the vial and its contents, and vesting title in her name.”

This is a very wise move on her part. NASA has for years made it clear that it thinks it owns all moon material brought back by the Apollo missions, and has had the arrogant policy of demanding the return of any moon dust or rocks that it discovered was in the possession of any private citizen, no matter how small, or how well documented the ownership. This court case acts to block such actions, before NASA can even think of them.

Kukla, Fran and Ollie – Here We Are Again

6:01 pm

A evening pause: Hat tip Jim Mallamace, who writes, “Before there was Shari Lewis; before there were the Muppets, there was Kukla, Fran, and Ollie. An American television staple from 1947 – 1957, Kukla, Fran, and Ollie demonstrated there would be as large an adult audience for puppetry as there was a child audience. Burr Tillstrom voiced all the puppets. Fran Allison was the host. In this video, they sing their theme song ‘Here We Are Again.'”

Do a quick search on youtube and you can find clips of them singing songs from things like The Mikado and doing satire on television advertising. As primitive as it might seem when compared to modern television, this was a children’s show with a whiff of sophistication.

Wernher von Braun material up for auction

9:18 am

Original material by Wernher von Braun that formed the basis for three classic 1950s coffee table books about the future of space is up for auction.

A collection of some of the most important seminal documents of the Space Age are open for bids as rocket pioneer Wernher von Braun’s “Man Will Conquer Space Soon” archive goes on the block. A collection of signed technical drawings, schematics, memos, orbital diagrams, and mathematical calculations related to von Braun’s efforts to sell an ambitious space program to both the American public and the US government, it’s the centerpiece of the Space and Aviation Auction at Boston-based RR Auction through April 19.

On March 22, 1952, the American weekly feature magazine Collier’s hit the newsstands. Among its usual mixture of advertisements and articles was the first of a series of features that would run for the next two years. These seemed like the wildest science fiction at the time, but would become established fact within a surprisingly few years. The series was called “Man Will Conquer Space Soon” and included painstakingly detailed color illustrations by magazine artists Chesley Bonestell, Fred Freeman, and Rolf Klep. It outlined a complete program for building an unmanned satellite, a manned space shuttle, a space station, an expedition to set up an outpost on the Moon, and topped it off with the conquest of Mars.

Later compiled into and expanded by three coffee table books – Across the Space Frontier (1952), Conquest of the Moon (1953), and The Exploration of Mars (1956) – the series was the brainchild of Wernher von Braun, one of the great rocket pioneers of the 20th century. He was the man behind Germany’s V2 rocket, and architect of the Saturn V booster that would send the first men to the Moon on the Apollo missions.

Those coffee table books are three of my most prized books in my somewhat large library. Anyone who was involved in the 1960s space race read them. When I was old enough to read I found them in my local library. They formed the basis of Disney movies, television shows, and rides at Disneyland. Other Hollywood productions were influenced by them. And most important of all, young men like Jim Lovell were influenced by them, making them want to be astronauts.

Jimi Hendrix On An Acoustic Guitar

6:01 pm

An evening pause: There are two clips, with the second beginning at 4:37. This is I think more interesting than good. The first clip is well shot, but it clearly is an unfinished music video because Hendrix himself I think was unsatisfied with his performance. The second is better performed, as it is a improvised performance at what appears to be a party. Regardless, they are worth watching because even when he played below par you can see he is playing at a level above most.

R.I.P. Ed Charles

11:42 am

Ed “Glider” Charles, the third basemen for 1969 Miracle Mets of New York, has passed away at 84.

Few today will know his name. No matter. Charles was a poet, a kind soul, a leader of men, and a fine athlete. From the article:

The Mets released a statement on the Glider’s passing. “Ed Charles, our beloved Glider and Poet Laureate of the 1969 Mets, was one of the kindest and warmest people ever to be a Met. His essays and poems inspired his teammates to the improbable World Series championship. With Jackie Robinson as his role model, Ed perpetuated a legacy of making a positive impact on other people’s lives. Everyone at the Mets are sending condolences, thoughts and prayers to Ed’s longtime companion Lavonnie Brinkley, his two sons Edwin and Eric, sister Virginia Charles and brother Elder.”

For those who lived and watched the incredible, now almost unbelievable miracle that produced the 1969 World Champion New York Mets, Ed Charles is a person who will never be forgotten.

University of Chicago to cease support of Yerkes in October 2018

2:26 pm

The University of Chicago announced today that it will cease all support of the Yerkes Observatory, home of the world’s largest refractive telescope, in October 2018.

The University of Chicago has announced plans to wind down its activities at Yerkes Observatory in Williams Bay, Wis., over the next six months and to formally cease on-site operations by Oct. 1, 2018.

The upcoming summer season will therefore be the final season of University activities at Yerkes. The University is announcing the plans well in advance in order to engage with Yerkes staff and nearby communities, including the village of Williams Bay, in considering long-term plans for the property.

The telescope is no longer useful for scientific research, but it is historically important, and as the press release admits, “has continued to make important contributions through its education and outreach programs.” And while I can understand their decision, they sure didn’t leave the staff at Yerkes much time to find new backers. When the National Science Foundation decided it was dropping support for its telescopes at Kitt Peak, it gave them literally several years to round up new support.

America’s first space weatherman gets to say “Go!” again

9:24 am

John Meisenheimer, the launch weather officer who gave the go-ahead for the first successful American satellite launch, Explorer 1 on January 31, 1958, was honored at the 60th anniversary of that first launch by having him to give the go-ahead for GovSat 1, launched on January 31, 2018.

The story is very touching, especially because Meisenheimer had scrubbed the Explorer 1 launch twice previously because he did not trust the weather. In 1958 he alone had that power, and no one questioned it. When the rocket flew, it was because he had decided the weather was no longer an issue.

Abraham Lincoln – a tribute on his birthday

6:01 pm

An evening pause: It is Abraham Lincoln’s birthday. It is time to once again repost this Lincoln tribute. As I have said previously, it is necessary we remember again the amazing good will he repeatedly expressed, even to those who hated him and wished to kill him. As I said in 2015:

We should also remind ourselves, especially in this time of increasing anger, bigotry, and violence, of these words from his second inaugural address, spoken in the final days of a violent war that had pitted brother against brother in order to set other men free:

Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondsman’s two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said “the judgments of the Lord are true and righteous altogether.”

With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation’s wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.

San Francisco area #1 in nation for fleeing residents

9:40 am

Fleeing the communist state: The San Francisco area is now #1 in the nation in the number of residents fleeing for more hospitable regions.

Joint Venture Silicon Valley’s own study of the out-migration says workers are moving to Sacramento, Austin, and Portland due to a number of factors. But topping the list is the high cost of housing. “You can’t even contemplate getting into the housing market here,” Hancock said. “And I don’t mean just service workers, but highly skilled professionals. The tech elite are having a hard time affording reasonable housing in Silicon Valley. That makes it difficult for employers to recruit.”

The article however also cites the politics of the region.

Dabak cites crowding, crime and politics as the reasons for her own exodus. “We don’t like it here anymore. You know, we don’t like this sanctuary state status and just the politics,” she said. She plans to sell her home for about $1 million, buy a much larger place near Nashville for less than half that and retire closer to family and friends.

I am reminded of East Germany in the 1950s. Ruled by the Soviets and the communists they installed (whom today we might call radical leftists), it became the only western nation in the world that had a shrinking population, mostly because of the vast numbers of residents that were fleeing to West Germany, where they were free to make a living as they wished. In East Germany’s communist state they were poor and oppressed. In West Germany’s capitalist state they could be prosperous and free.

To solve this problem, Khrushchev built a wall between East and West Germany, to imprison his citizens. When they continued to flee, using the loophole that existed in Berlin (with half its territory controlled by the western Allies), he then built a wall through the middle of the city. It stopped the population loss, while making the residents of his communist bloc prisoners.

What will the leftist radicals who now run California do? As people flee their bankrupt state, will they then decide to build a wall to keep people in? I wonder.
