Balanced rock on Mars

10:00 am

Balanced rock on Mars

Cool image time! Prior to going into safe mode Curiosity’s mast camera took a series of images of its surroundings, as is routine as the rover travels. Among those images was the image above, though I have cropped it and reduced its resolution to show here. It reveals a balanced rock on the horizon. It also shows, as do the other survey images, how increasingly rough the terrain is becoming that Curiosity is traveling through.

The Curiosity science team has no intention of getting too close to this rough terrain, but they do hope to get better views of this rock as they continue the rover’s journey uphill.

New Hubble image of Crab Nebula

9:42 am

Crab Nebula

Cool image time! Scientists have released a new Hubble Space Telescope image taken of the innermost regions of the Crab Nebula, the remains of a supernova explosion that took place a thousand years ago in 1054.

On the right is a reduced resolution version of this new image. I have also cropped it to focus on the nebula’s center, where the pulsar is located. The circular concentric rings are exactly what they appear to be, ripples of energy spreading out from the pulsar. Back in 2002 Hubble took a series of images of the Crab Nebula over several days, which scientists then assembled into a movie showing these waves as they emanated out from the nebula’s center.

My only complaint with this beautiful new image is that they did not take a longer series of new exposures to create a longer movie, to better show the actual daily changes that the nebula undergoes. It seemed obvious to do then, and obvious to do now. Yet, it hasn’t happened.

The image download page for today’s release is here.

Hotel clerk loses her job and might be jailed for reporting suspicious behavior

9:48 pm

Madness: A hotel clerk who called 911 because a Muslim man was behaving strangely about getting a room during the Republican convention in Cleveland has been fired and might be prosecuted by the local authorities.

Read the whole article. The Muslim man was asking odd questions, refused to accept the fact that all the rooms were booked, and had multiple cellphones. The article also includes the transcript of the clerk’s 911 call, which clearly shows she was not trying to profile unfairly but thought it wise to let the police know about what was happening.

In a sane world, the hotel and the police would simply drop things. Instead, the hotel fired the clerk, and the police are considering prosecuting her. And people wonder why Islamic mass murderers can literally announce on social media what they intend to do and no one reports it.

Curiosity in safe mode

4:31 pm

For the first time in three years, Curiosity has entered safe mode.

On July 2, Mars rover Curiosity ceased science operations on the slopes of Mount Sharp after a fail safe was tripped, forcing the nuclear-powered robot into a low-power “safe mode.” According to a NASA Jet Propulsion Laboratory report, preliminary information communicated by Curiosity suggests an “unexpected mismatch between camera software and data-processing software in the main computer” may have been the culprit and the rover’s automated systems took over, preventing any permanent damage from being caused.

They are in communications with the rover, and expect a full recovery.

Weird dunes on Mars

11:11 am

Weird dunes on Mars

Cool image time! The image on the right, cropped and reduced in resolution to fit here, shows an area of inexplicable dark dunes located in Mars’ high northern latitudes. Located in a circular depression (whose outline can be seen across the top and left side of the image), geologists only partly understand the processes producing these dunes. As the noted on the release webpage:

However, a circular depression (probably an old and infilled impact crater) has limited the amount of sand available for dune formation and influenced local winds. As a result, the dunes here form distinct dots and dashes. The “dashes” are linear dunes formed by bi-directional winds, which are not traveling parallel to the dune. Instead, the combined effect of winds from two directions at right angles to the dunes, funnels material into a linear shape. The smaller “dots” (called “barchanoid dunes”) occur where there is some interruption to the process forming those linear dunes. This process is not well understood at present and is one motivation for HiRISE to image this area.

Be sure to look at the full image, as it covers a wider area and shows dunes that travel in all directions, forming mazelike patterns that no theory presently explains.

Auction of first published book describing Copernicus’ heliocentric theory

8:53 am

Got some spare cash? On July 13, the auction house Christies in London will be selling a first edition of the first book ever published describing Copernicus’ theory that the Earth orbited the Sun.

De Libris Revolutionum Eruditissimi Viridoctoris came not from Nicolaus Copernicus, but from his only student, Georg Joachim Rheticus, and when published in 1540, provided the momentum needed for Copernicus to finally have his landmark De revolutionibus orbium coelestium published in 1543.

Rheticus (1514-1574) published this first book on the subject based on his studies under Copernicus, all the while imploring his master to finally publish the master work which had been finished for 25 years. Copernicus resisted publishing De revolutionibus orbium coelestium for 30 years due to his fear of the Catholic Church, but when Rheticus published this book in 1540, Copernicus finally gave Rheticus the go ahead to publish the major work for him.

Cubesats to the planets!

8:47 am

Link here. The article is a good detailed overview of the many upcoming planetary missions that are using small and relatively inexpensive cubesats as either part of their mission, or are the mission itself.

This trend also partly explains the number of new rocket companies like Rocket Lab and Firefly Space Systems that are developing small rockets aimed at launching cubesats. These companies have recognized a growing demand, and are trying to serve it. As the article notes,

Lifts are so hard to come by that the first interplanetary CubeSat — NASA’s twin INSPIRE mini-spacecraft, intended to test key technology for future missions — has been waiting for almost two years. “We still have to find a ride,” says Anthony Freeman, who manages the Innovation Foundry at NASA’s Jet Propulsion Laboratory in Pasadena, California.

Another Obamacare co-op to fold

5:54 pm

Finding out what’s in it: The fourteenth of the original twenty-three Obamacare state health insurance co-ops has announced it is closing shop.

I like this quote from the article:

Grace-Marie Turner, president of the Galen Institute, which advocates for free-market solutions in the health industry, said those who wanted the co-ops to be part of Obamacare believed “if they didn’t have a profit, they could charge less money, provide more service.” But she said the cascade of failures “is an indictment of the idealistic notion that you could put people in charge of billions of dollars who have little or no experience in the insurance industry.”

Across the country, the federal government loaned $2.4 billion to launch the co-ops [emphasis mine]

In other words, Obamacare was written and run by people didn’t have the slightest idea what they were doing, but they not only went ahead with it, but then handed out billions in taxpayer money to their friends, money that will never be returned. Pretty good gig, if you can get it!

A short but weak solar maximum?

3:03 pm

On July 4th NOAA released its monthly update of the solar cycle, showing the Sun’s sunspot activity in June. It is annotated and posted below.

June 2016 Solar Cycle graph

The graph above has been modified to show the predictions of the solar science community. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction.

Not surprisingly, the time periods with no sunspots in June, including a 12 day stretch that just ended today, is reflected by the graph’s precipitous drop in June.

What is significant to me is the speed with which this solar maximum seems to be ending. Normally, weak solar cycles are also long solar cycles. The Sun not only doesn’t get as active, but the ramp up and down is extended, as is the period of the solar minimum. This is what happened during the solar minimum from 2007 to 2010. It was longer than normal, which meant that the solar maximum occurred much later than predicted by the 2007 predictions of the solar science communities (shown in green).

This recent stretch of blank days however is now suggesting that the solar maximum is going to end much sooner than the later 2009 prediction (shown in red). Even more astonishing, the numbers in June aligned with the 2007 high prediction, which would make this one of the shortest solar maximums on record!

I don’t expect these low numbers to continue. I expect sunspot activity to recover and continue, with the minimum likely occurring after 2018. If it does come sooner, however, that will once again be evidence suggesting we are heading for a Grand Minimum, with no sunspots for decades.

Court rules Obama adminstration can’t use private email accounts to bypass law

9:57 am

I love the timing: A federal court today ruled that government officials in the White House Office of Science and Technology Policy (OSTP) cannot use private email accounts to evade public record laws.

Throughout the case, the government argued that “[d]ocuments on a nongovernmental email server are outside the possession or control of federal agencies, and thus beyond the scope of FOIA.”

Judge David Sentelle, the chief judge of the U.S. Court of Appeals for the D.C. Circuit, disagreed with that reasoning and ordered the lower court to reconsider the case. “If a department head can deprive the citizens of their right to know what his department is up to by the simple expedient of maintaining his departmental emails on an account in another domain, that purpose is hardly served,” Sentelle wrote. “It would make as much sense to say that the department head could deprive requestors of hard-copy documents by leaving them in a file at his daughter’s house and then claiming that they are under her control,” he said.

This absurd rulling, which says that government officials have to follow the law, will surely be overturned. We can’t have these saints oppressed by things as evil as the law.

The fix for Hillary Clinton is IN

8:45 am

The law is for little people: The head of the FBi today spoke to reporters, outlining in detail how Hillary Clinton and her aides repeatedly broke the law in their use of her private server to send and receive classified State Department emails. Because of these facts, he of course concluded that no reasonable prosecutor would bring charges, and therefore will not make any recommendations to the Department of Justice.

You can read his entire surreal statement here.

As noted correctly here, “The cover-up is now finished.” Or as this writer noted recently

Now it seems we actually have a new social contract – do what we say and don’t resist, and in return we’ll abuse you, lie about you, take your money, and look down upon you in contempt. What a bargain!

It’s not a social contract anymore – American society today is a suicide pact we never agreed to and yet we’re expected to go first.

I say “No.”

We owe them nothing – not respect, not loyalty, not obedience. Nothing.

We make it easy for them by going along. We make it simple by defaulting to the old rules. But there are no rules anymore, certainly none that morally bind us once we are outside the presence of some government worker with a gun to force our compliance. There is only will and power and we must rediscover our own. If there is no cop sitting right there, then there is nothing to make you stop at that stop sign tonight.

They don’t realize that by rejecting the rule of law, they have set us free. We are independent. We owe them nothing – not respect, not loyalty, not obedience. But with a firm reliance on the protection of divine Providence, we will still mutually pledge those who have earned our loyalty with their adherence to the rule of law, our lives, our fortunes and our sacred honor.

It is especially ironic that the FBI’s announcement that it was going to help cover-up illegal activity by a high government official was made one day after the Fourth of July.

1776 – Hatching an Egg

6:01 pm

An evening pause: For the Fourth of July, this song from the 1976 movie version of the 1972 musical, 1776. Not only did the musical capture the essence of the men who made independency happen, it is also a rollicking and entertaining work of art.

I last posted this piece last in 2010. Time to watch again.

European experimental space junk removal mission to launch

4:46 pm

The competition heats up: A European Space Agency mission to test technologies for removing space junk will launch sometime next year.

Presented at the Royal Society’s summer science exhibition this week, and led by the Surrey Space Centre, the systems included a net, harpoon and drag sail, which scientists have incorporated into a test platform for launch into space. The platform will also carry “artificial junk” in the form of small satellites known as CubeSats.

Once the platform is launched into space, a CubeSat will be released. “The CubeSat will be ejected from the platform and then we’ll fire the net at it,” said Forshaw. The CubeSat, hopefully encased in the net, will then fall back towards Earth and burn up. In the case of the harpoon, the researchers have attached a target made of spacecraft material to a carbon-fibre boom that extends from the platform. “When the harpoon impacts it, it is actually going to simulate a real spacecraft being hit,” said Forshaw.

At the end of the mission the third system, a drag sail will be deployed. Attached to the platform, the sail will speed up its return to Earth where it will burn up in the atmosphere. Similar systems have been proposed for future satellites to allow them to be disposed of without leaving space junk.

With the Chinese, NASA, and private companies all developing robotic missions to either clean up space junk or repair satellites, the competition to do this work is going to get very intense in the next decade.

The American Revolution, as reported by modern reporters

10:24 am

To better understand how the teaching of American history is being distorted by modern leftist historians, one need only read this description of the beginnings of the American Revolution, written as it almost certainly would be by today’s ignorant and leftwing anti-American journalists:

Boston – National Guard units seeking to confiscate a cache of recently banned assault weapons were ambushed by elements of a Para-military extremist faction. Military and law enforcement sources estimate that 72 were killed and more than 200 injured before government forces were compelled to withdraw.

Speaking after the clash, Massachusetts Governor Thomas Gage declared that the extremist faction, which was made up of local citizens, has links to the radical right-wing tax protest movement.

Read it all. It will sound sadly very familiar.

The Declaration of Independence

10:07 am

It behooves every American to read at least once a year the document that outlined the principles and reasons why the American colonies declared their independence from Great Britain. These words remain its most profound statement:

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.

It seems that the Fourth of July seems the most appropriate day for that reading.

The story of the writing of the Battle Hymn of the Republic

9:55 am

Some more Civil War history on this July fourth.

The Battle Hymn of the Republic became one of the most popular songs in the North during the Civil War, and was also an important rally song used during the 1950s/1960s civil rights movement. And its central theme is stated by its last stanza:

In the beauty of the lilies
Christ was born across the sea,
With a glory in His bosom
That transfigures you and me;
As He died to make men holy,
Let us die to make men free;
While God is marching on.

That stanza in many ways encompasses much of American history, since many of the original colonies were formed by deeply religious Christians who had made their religion and its moral rules central to their lives. That faith ended up being seeped in much of American culture for the next four hundred years, and guided the country’s actions both in domestic and foreign policy.

Federal court rules a farmer plowing his land violates Clean Water Act

9:14 pm

Fascists: A federal court has ruled that a farmer in California is violating the Clean Water Act by plowing his own property.

The court ruled that the company violated the Clean Water Act by plowing its property, even though the Act exempts normal farming practices. And, the implementing regulations state that plowing is never even subject to the Act, so long as it does not convert wetlands to dry land. Since no wetlands were lost or reduced in acreage by the plowing in this case, the court’s decision amounts to a rule that you may not plow in federally regulated wetlands without an Army Corps permit, the clear exemptions to the contrary notwithstanding.

The court also reversed an earlier ruling in the case and held that although the Corps ordered Duarte Nursery to halt all activity in any area of its property that could be considered waters of the U.S. on its property, the company did not suffer any deprivation of its property. On this basis, the court then ruled that Duarte Nursery’s due process rights have not been violated by being ordered not to farm its property for the last three years.

More here. Even though the Supreme Court has twice told the EPA and the Army Corp of Engineers that their interpretation of the Clean Water Act is wrong and overreaching, the agencies continue to use their interpretation to fine and restrict the actions of farmers and private property owners. In this case, they are forbidding a farming company from farming their property under Clean Water Act regulations, even though the law specifically exempts farming from Clean Water Act regulations and the Supreme Court has also ruled that interpretation of the law by these agencies is wrong.

What makes this worse is that a California federal court has agreed with the agencies, even though the Supreme Court has previously ruled otherwise. It is as if the lower federal court in California have decided they don’t need to follow the rulings of the higher court.

Microsoft gives people another reason to dump Windows

9:14 am

Why I use Linux: In its effort to convince users of earlier versions of Windows to upgrade to Windows 10, Microsoft is now inserting a full screen pop-up upgrade notification, often at decidedly unwanted moments.

The Redmond software giant confirmed today it will start showing dark blue screens urging people to install the latest version of Windows. The full-screen ads will pop up on Windows 7 and 8.1 desktops from now until July 30, when the free upgrade period ends.

Getting and Installing Linux – Part 2

6:01 am

Obtaining and installing a Linux Distribution

by James Stephens

Almost any Linux distribution runs great on today’s hardware. But I’m writing this with aging computers in mind. With older computers it’s a good idea to know how much RAM (often referred to as physical memory) you have in order to select a distribution that will work well with your machine.

With Windows this can be shown by opening “System” in “Control Panel.” RAM or physical memory will be expressed in Mb or Gb. Once you know this, you are armed with the knowledge to select a distribution.

For machines with 512 Mb RAM and up I recommend a distribution from LinuxMint. For machines with under 512 Mb RAM I recommend Bodhi Linux 32 bit legacy.

Operating systems come in 32 bit and 64 bit versions. With the exception of replacing Windows 8.1 and 10, a 32 bit distribution will work on any computer. (More about Microsoft and UEFI later.) At one time a 64 bit opening system allowed the use of more memory then it’s 32 bit kin. But with modern 32 bit distributions this is no longer an issue. So if you want to play it safe choose a 32 bit distribution.

LinuxMint offers a choice of desktops and the website does a good job explaining the advantages of each. I would recommend LinuxMint 17.3 MATE 32 bit edition as most likely to work on any computer. But take a look at each of them and see which one you like. As long as you follow the minimum RAM requirements guidelines as listed in the description you will be okay.

TSA injures and arrests a disabled teenager, because they can

3:58 pm

Does this make you feel safer? A disabled teenager, partially deaf, blind in one eye, paralyzed, and easily confused, was injured and then arrested by TSA agents at Memphis Airport when they tried to subject her to a hands-on body scan.

Despite her concerns, Shirley [the mother] was kept away from her daughter by police. Hannah, obviously afraid, tried to get away from the grips of the TSA. “She’s trying to get away from them but in the next instant, one of them had her down on the ground and hit her head on the floor. There was blood everywhere,” said Shirley.

The teen was arrested, booked, and sent to jail. “Here we were with nowhere to go, not even a toothbrush, our bags had gone to Chattanooga,” said the distraught mother.

The mother is suing the airport, the TSA, and the local police, all of whom acted like brainless thugs, especially since anyone with any brains would have likely realized instantly that the girl was not a threat to anyone.
