Berkeley students block pedestrian bridge to whites

9:40 am

Fascists and bigots: Protesting students at the University of California-Berkeley blocked whites from access to a pedestrian bridge while apparently also demanding segregated spaces for non-white students.

A video of the protest shows demonstrators repeatedly heckling white passersby, barring them entry to a key bridge on campus by forming a human chain while simultaneously allowing students of color to pass unmolested. At one point, the video even shows a protester refusing to allow an older white man to cross the bridge, eventually directing him to cross by way of a creek that flows underneath the bridge.

As I have said, the hate is real. These are dangerous people, absolutely convinced and certain that they are right. This certainty in turn gives them the right to oppress anyone who either disagrees with them or happens to not belong to their favored ethnic or racial group.

The KKK would understand entirely.

Vandal destroys Trump’s Hollywood sidewalk star

9:23 am

The hate is real: A man Vandal using a sledgehammer and a pick-ax destroyed Donald Trump’s Hollywood Walk of Fame sidewalk star.

Understand this above all else: Should Donald Trump win the election the left will not accept his victory, and will make an organized effort to undermine anything he tries to do. And this effort will include a vast majority of government workers, whose campaign contributions favor Hillary Clinton by 18-1.

This is why I found the media uproar last week about Trump’s suggestion that he would not accept the election results to be laughable. Should Clinton lose, the left is going to exhibit far more denial of the election results than anything you can imagine that might come from the right. Their response will be violent, it will be sustained, and it will repeatedly defiant of the law.

Update: I had hardly finishing writing the above when I came upon this story: ‘Angry protesters’ to storm D.C. Trump hotel grand opening. And this will only be a taste.

The effect of weightlessness on the spine

9:04 am

New observations of astronauts before and after four to seven month long missions to ISS has found the back pain many astronauts experience appears to be caused by significant muscle atrophy.

The MRI scans indicated significant atrophy of the paraspinal lean muscle mass —which plays a critical role in spinal support and movement—during the astronauts’ time in space. The lean muscle, or “functional,” cross-sectional area of the lumbar paraspinal muscles decreased by an average of 19 percent from preflight to immediate postflight scans. A month or two later, only about two-thirds of the reduction had recovered. There was an even more dramatic reduction in the functional cross-sectional area of the paraspinal muscles relative to total paraspinal cross-sectional area. The ratio of lean muscle decreased from 86 percent preflight to 72 percent immediately postflight. At follow-up, the ratio recovered to 81 percent, but was still less than the preflight value.

In contrast, there was no consistent change in the height of the spinal intervertebral discs. Dr. Chang and coauthors write, “These measurements run counter to previous hypotheses about the effects of microgravity on disc swelling.” Further studies will be needed to clarify the effects on disc height, and whether they contribute to the increase in body height during space missions, and to the increased risk of herniated disc disease.

These results are very encouraging, because they indicate that the back problems seen are mostly attributable to weakened muscles, not actual spinal damage, and can therefore be more easily mitigated by new exercises while in orbit.

Clinton campaign outlines its space priorities

8:55 am

In an op-ed today, an adviser to the Hillary Clinton campaign outlined the space policy priorities that her administration would focus upon should she win the election.

Despite attempts to suggest these policies would be significantly different than the policies of Donald Trump, it seems to me that her focus would be quite similar to Trump’s. While the announcements from the Trump campaign have suggested his administration would consider more changes to space policy than Clinton, both candidates appear to be proposing only minor changes. With both, the private-public partnership of commercial space would be continued. With both, SLS/Orion will be reconsidered, and changed depending on the demands of Congress.

The only significant difference, based on today’s op-ed, is that a Hillary Clinton administration will likely devote significant NASA resources to the study of global warming, while Trump appears quite willing to slash this research, based on what appears to be data tampering for political reasons in both NASA and NOAA.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

Aggressive SETI observations of Tabby’s star upcoming

8:29 am

Breakthrough Listen, an effort to listen for radio signals from alien civilizations that, plans to devote significant time this year observing Tabby’s star to see if an alien mega-structures are causing that star’s unexplained dimming.

While Siemion and his colleagues are skeptical that the star’s unique behavior is a sign of an advanced civilization, they can’t not take a look. They’ve teamed up with UC Berkeley visiting astronomer Jason Wright and Tabetha Boyajian, the assistant professor of physics and astronomy at Louisiana State University for whom the star is named, to observe the star with state-of-the-art instruments the Breakthrough Listen team recently mounted on the 100-meter telescope. Wright is at the Center for Exoplanets and Habitable Worlds at Pennsylvania State University.

The observations are scheduled for eight hours per night for three nights over the next two months, starting Wednesday evening, Oct. 26. Siemion, Wright and Boyajian are traveling to the Green Bank Observatory in rural West Virginia to start the observations, and expect to gather around 1 petabyte of data over hundreds of millions of individual radio channels.

Russia and ESA in money dispute

9:40 pm

A money dispute between Russia and France could threaten the ESA/Russian ExoMars partnership, as well as the Arianespace deal that launches Soyuz rockets from French Guiana.

In what appears to be an attempt to force France’s European neighbors to apply pressure to Paris, Roscosmos hinted that multiple cooperative space efforts between Russian and the European Union, and with the European Space Agency (ESA), could suffer if the payments are not freed. The payments, which are not disputed by Arianespace, have been one of the collateral effects of the battle by former shareholders of Russia’s Yukos oil company. In 2014, these shareholders won an initial award of $50 billion from an international arbitration panel in The Hague, Netherlands, against the Russian government for dismantling the company.

Since then, the shareholders have been trying to collect Russian government assets wherever they find a sympathetic legal environment outside Russia, including France and Belgium. In France, different shareholder representatives sought seizure of the Eutelsat and Arianespace payments. The same dispute has blocked payments to other Russian companies. Paris-based satellite operator Eutelsat owes Russia’s biggest satellite operator, Russian Satellite Communications Co. (RSCC) of Moscow, around $300 million for services related to Eutelsat use of RSCC satellites.

Russia needs cash, which is why they need their partnership with Arianespace, which has brought them a lot of cash over time. Their problem is that the money owed the Yukos oil company shareholders has allowed those shareholders to put liens on any Russian earnings in Europe, which has only increased Russia’s financial bind. If Russia can’t get its hands on its Arianespace earnings, then it really makes no sense for them to continue the partnership. Better to threaten to pull out with the hope that the threat will maybe force payment.

Moreover, Russia might also be realizing that it cannot at present afford to participate in ExoMars and is looking for a way to get out of that commitment. This money dispute gives them that out.

Juno successfully completes engine burn with smaller thrusters

7:01 pm

Having successfully left safe mode, engineers had Juno do a 31 minute engine burn on Tuesday to adjust its orbit using its smaller thrusters.

The burn, which lasted just over 31 minutes, changed Juno’s orbital velocity by about 5.8 mph (2.6 meters per second) and consumed about 8 pounds (3.6 kilograms) of propellant. Juno will perform its next science flyby of Jupiter on Dec. 11, with time of closest approach to the gas giant occurring at 9:03 a.m. PDT (12:03 p.m. EDT). The complete suite of Juno’s science instruments, as well as the JunoCam imager, will be collecting data during the upcoming flyby.

That they will definitely collect data during the December 11 flyby means that they are going to delay again the main engine burn that will reduce the spacecraft’s orbit to 14 days, its official science orbit. This also means that they are still uncomfortable firing that main engine. It is also not clear from the press release whether this burn was planned, or was added to compensate for the main engine issues.

The vagueness makes me think that Juno has some serious issues that they haven’t yet told us about.

Court awards $197K to Christians

12:11 pm

Good news: A federal court has awarded $197K to a group of Christian evangelicals who police threatened to arrest for preaching at a Michigan Arab festival.

The Christian were threatened by a violent mob, which had started throwing rocks at them and were threatening even worse violence. Rather than protect them, however, the Dearborn police instead told the Christians they had to leave, or be arrested for disorderly conduct. In other words, at this Arab festival the police unilaterally decided to suspend their freedom of speech and allow the heckler’s veto to win. If you don’t believe me, you can see exactly what happened in the the video below the fold.

The court had previously ruled in favor of the Christians, but what makes this final decision significant is that it declares the policemen themselves personally liable.

In its decision, which was made final today by the entry of judgment in the district court, the Sixth Circuit ruled, among other things, that two Deputy Chief defendants from the Wayne County Sheriff’s Office were liable for violating the Christians’ First Amendment rights to free speech and the free exercise of religion and for depriving the Christians of the equal protection of the law. The court ruled that these individual defendants did not enjoy qualified immunity.

In other words, if you are a cop and deny someone their first amendment rights — threatening them with arrest for exercising those rights — you can be found personal liable in court and end up paying that individual a lot of money for denying them their rights.

London university pockets millions for fake global warming research

10:41 am

Follow the money: The research center at a major London university has obtained millions in government grants for global warming research it did not do.

A global warming research center at the London School of Economics got millions of dollars from UK taxpayers by taking credit for research it didn’t perform, an investigation by The Daily Mail revealed. The UK government gave $11 million dollars to the Centre for Climate Change Economics and Policy (CCCEP) in exchange for research that the organization reportedly never actually did.

Many papers CCCEP claimed to have published to get government money weren’t about global warming, were written before the organization was even founded, or were written by researchers unaffiliated with CCCEP. The government never checked CCCEP’s supposed publication lists, saying they were “taken on trust,” according to the report. “It is serious misconduct to claim credit for a paper you haven’t supported, and it’s fraud to use that in a bid to renew a grant,” Professor Richard Tol, a climate economics expert from Sussex University whose research was reportedly stolen by CCCEP, told The Daily Mail. “I’ve never come across anything like it before. It stinks.”

The crime here is not just the fraud committed by the research center. The negligence of the government in handing out these grants without doing any due diligence is equally criminal. And I am being kind. I suspect that it wasn’t negligence but straightforward corruption. I think these grants were likely given for political reasons. Rather than fund real research, the money was intentionally handed out to political supporters in order to advocate global warming politics.

Brownshirts vandalize and attack neighbors’ homes of Republican senator

10:24 am

Fascists: The homes of the neighbors of Senator Pat Toomey (R-Pennsylvania) were spray-painted this past weekend with anti-Republican hate speech.

The graffiti sprayed late Saturday or early Sunday says, “Nazi, Slavers, Rapists, Cross-Worshippers== GOP.” Another message says, “Look Out Toomey and Your Neo Nazi Republicans,” and a third says hashtag “Americans Against the Republican Party.”

Even though Toomey’s Democratic election opponent condemned the attack, the recent videos that showed the Democratic Party hiring thugs to instigate violence at Trump rallies makes me wonder if that party was somehow involved in this vandalism. And even if it was not, the attack tells us a great deal about the violent and hateful intolerance that percolates through the liberal Democratic Party.

The storms of Jupiter’s south pole

10:12 am

storms on Jupiter

Cool image time! Even though Juno has been unable to gather any additional data since its first close approach of Jupiter in August because of technical problems, the science team has set up its website to allow the public to download the images produced so far, process those images, and then upload them to the site for the world to see.

The image to the right, reduced in resolution to show here, is one example of the many different processed images produced by interested members of the general public. It highlights the seemingly incoherent storms that are raging at Jupiter’s south pole.

close-up of storms

To the left is a cropped section of the full resolution image. It shows the complex transition zone between the darker polar regions and the brighter band that surrounds it. This chaotic atmospheric behavior is something that no climate scientist has ever seen before. It will take decades of research to untangle and even begin to understand what is happening.

Schiaparelli failure focuses in on altimeter data

9:50 am

The investigation into the landing failure last week of the ExoMars 2016 lander, Schiaparelli, is now focusing on a failure in the spacecraft’s altitude software.

The most likely culprit is a flaw in the craft’s software or a problem in merging the data coming from different sensors, which may have led the craft to believe it was lower in altitude than it really was, says Andrea Accomazzo, ESA’s head of solar and planetary missions. Accomazzo says that this is a hunch; he is reluctant to diagnose the fault before a full post-mortem has been carried out. But if he is right, that is both bad and good news.

European-designed computing, software and sensors are among the elements of the lander that are to be reused on the ExoMars 2020 landing system, which, unlike Schiaparelli, will involve a mixture of European and Russian technology. But software glitches should be easier to fix than a fundamental problem with the landing hardware, which ESA scientists say seems to have passed its test with flying colours. “If we have a serious technological issue, then it’s different, then we have to re-evaluate carefully. But I don’t expect it to be the case,” says Accomazzo.

Russia considers using Ukrainian rocket

9:46 am

For the first time since it annexed Crimea, Russia has opened negotiations with a Ukrainian company to possibly use its Zenit rocket to launch a Russian satellite.

RKK Energia of Korolev, Russia, entered negotiations with KB Yuzhnoe of Dnepropetrovsk, Ukraine, on a potential deal to launch a satellite for Angola on a Ukrainian-built Zenit rocket. Under the proposed plan, the Angosat-1 satellite would ride the last fully assembled Zenit rocket still remaining in Baikonur. The mission is seen by industry insiders as the first step in the resumption of Zenit missions, which if successful, will eventually shift from Baikonur to the Sea Launch ocean-going platform based in Long Beach, California.

The situation here is beyond complicated. Russia remains in many ways in a state of war with Ukraine. Yet, the Sea Launch platform, recently purchased by a Russian airline company, needs the Ukrainian Zenit rocket. It appears that this need is forcing the Russians to once again buy from the Ukraine. At the same time, Sea Launch remains parked in the U.S., and will likely not be available until Sea Launch and Russia settle the lawsuit Boeing has filed against the company. Meanwhile, the Zenit rocket in question however needs refurbishing and was originally built to launch a different satellite, which will have to agree to fly on a different launch vehicle.

ISRO begins ground tests of its first lunar lander

9:36 am

The competition heats up: ISRO, India’s space agency, has begun testing the sensors its first lunar lander, Chandrayaan-2, will use to descend safely to the surface.

ISRO Satellite Centre or ISAC, which is the lead centre for the country’s second moon mission, has artificially created eight to ten craters to make the terrain resemble the lunar surface. This terrain is now the test bed for the lunar Lander’s sensors. Between Friday and Monday, a small ISRO-owned aircraft carrying equipment with the sensors flew a few times over these craters to see how well they performed.

Obamacare premiums skyrocketing again

3:48 pm

Finding out what’s in it: The Obama administration today admitted that Obamacare premiums will skyrocket next year as the number of insurance companies available to consumers continues to decrease.

Before taxpayer-provided subsidies, premiums for a midlevel benchmark plan will increase an average of 25 percent across the 39 states served by the federally run online market, according to a report from the Department of Health and Human Services. Some states will see much bigger jumps, others less. Moreover, about 1 in 5 consumers will only have plans from a single insurer to pick from, after major national carriers such as UnitedHealth Group, Humana and Aetna scaled back their roles. “Consumers will be faced this year with not only big premium increases but also with a declining number of insurers participating, and that will lead to a tumultuous open enrollment period,” said Larry Levitt, who tracks the health care law for the nonpartisan Kaiser Family Foundation.

The Democrats wrote this monstrous stupid law. They forced it through Congress without a single Republican vote. Everything that has gone wrong since was predicted then, in 2010, by conservatives. Yet today, the public is still voting for these same Democrats.

We truly are facing the coming of a new dark age.

In related news, all the major hospitals in Chicago, home base for Obama and a Democratic Party stronghold for more than a century, have pulled out of Obamacare.

Musk answers questions on reddit

10:02 am

In a reddit Q&A session yesterday, Elon Musk answered a host of questions about his Mars mission plans.

Key takeaway: They are far away from actually flying this rocket. The engine needs tests, its giant tanks need a great deal of development, and they are only beginning the concept work for the ship itself.

His comments on Falcon 9 re-usability, however, were somewhat more interesting, and far more grounded in present reality.

Musk did not answer any questions submitted about the status of the company’s Falcon 9 rocket, grounded since a Sept. 1 explosion during preparations for a static-fire test destroyed a Falcon 9 and its Amos-6 satellite payload. He did, though, briefly address an upcoming, and “final,” version of the rocket, which he called Block 5, that is designed for frequent reusability. “Falcon 9 Block 5 — the final version in the series — is the one that has the most performance and is designed for easy reuse, so it just makes sense to focus on that long term and retire the earlier versions,” he wrote. That version includes many “minor refinements” but also increased thrust and improved landing legs, he said.

The first of the Block 5 Falcon 9 vehicles will begin production in three months, with an initial flight in six to eight months. With its entry into service, he said he doesn’t expect recovered first stages from the older Block 3 and Block 4 versions of the rocket to be reused more than a few times.

In a speech earlier this month, SpaceX President Gwynne Shotwell said she believed the updated version of the Falcon 9 could be reused up to 10 times. Musk, though, was more optimistic. “I think the F9 boosters could be used almost indefinitely, so long as there is scheduled maintenance and careful inspections,” he said.

Changing seasons on Titan

9:15 am

Since entering Saturn orbit in 2004, Cassini has seen the seasons on Titan shift through half a Saturn year.

As Titan approaches its northern summer solstice, NASA’s Cassini spacecraft has revealed dramatic seasonal changes in the atmospheric temperature and composition of Saturn’s largest moon. Winter is taking a grip on the southern hemisphere and a strong vortex, enriched in trace gases, has developed in the upper atmosphere over the south pole. These observations show a polar reversal in Titan’s atmosphere since Cassini arrived at Saturn in 2004, when similar features were seen in the northern hemisphere.

Sadly, there will not be any spacecraft at Saturn during the second half of this Saturn year. After Cassini ends its mission in 2017 it will likely be many decades before another spacecraft arrives, since at this moment none has even been proposed.

Pentagon demanding return of cash bonuses given to soldiers a decade ago

9:56 pm

Evil. The government is routinely evil: The Pentagon is demanding that soldiers who ten years ago volunteered to re-enlist to fight in Iraq and Afghanistan in exchange for cash bonuses return those bonuses because new audits have revealed that the government had screwed up.

The Army asked wounded Iraq veteran and former Army captain Christopher Van Meter, 42, to repay a $25,000 reenlistment bonus it said he was ineligible to receive. He was also asked to repay $21,000 in student loan repayments. Van Meter told the paper that rather than fight the Army he paid back the money after refinancing his home. “These bonuses were used to keep people in,” Van Meter said. “People like me just got screwed.”

The Times reported that 48-year-old Army sergeant Robert Richmond, who suffered permanent injuries in an Iraq roadside bomb attack, is refusing to repay his $15,000 cash bonus. The Army contends he was ineligible to receive the bonus in 2006 because he had already served 20 years in the Army. “I signed a contract that I literally risked my life to fulfill,” Richmond told the paper. “We want somebody in the government, anybody, to say this is wrong and we’ll stop going after his money.”

Investigations determined that fraud and mismanagement due to poor oversight contributed to the California Guard bonus overpayments, according to the Times. [emphasis mine]

In other words, the government was either incompetent or downright corrupt a decade ago, and now wants soldiers who risked their lives but did their job well to suffer for that incompetence and corruption.

As I say, the government is routinely evil, and incompetent. It can’t do anything right, and will never take responsibility for its own disasters. Instead, it tries to pass its failures on to us all.

Science conference accepts fake paper

11:30 pm

I’m so glad it was peer-reviewed! A fake physics paper written entirely in gibberish using autocomplete function has been accepted by a science conference.

Christoph Bartneck, an associate professor at the Human Interface Technology laboratory at the University of Canterbury in New Zealand, received an email inviting him to submit a paper to the International Conference on Atomic and Nuclear Physics in the US in November. “Since I have practically no knowledge of nuclear physics I resorted to iOS autocomplete function to help me writing the paper,” he wrote in a blog post on Thursday. “I started a sentence with ‘atomic’ or ‘nuclear’ and then randomly hit the autocomplete suggestions. The text really does not make any sense.”

It only took the conference three hours to review the work and to accept it. They then asked the author to confirm his oral presentation and register for the conference for a mere $1099.

Saturn’s changing north pole

10:38 pm

A comparison of images taken by Cassini in 2012 and then in 2016 of Saturn’s north polar region shows a significant change in color.

Scientists are investigating potential causes for the change in color of the region inside the north-polar hexagon on Saturn. The color change is thought to be an effect of Saturn’s seasons. In particular, the change from a bluish color to a more golden hue may be due to the increased production of photochemical hazes in the atmosphere as the north pole approaches summer solstice in May 2017.

Moon found orbiting one of the larger known Kuiper belt object

6:22 pm

Astronomers have found a moon circling 2007 Or10, one of the Kuiper Belts eight largest objects and the only one as yet unnamed.

Astronomers Gábor Marton and Csaba Kiss (Konkoly Observatory, Hungary), and Thomas Müller (Max Planck Institute, Germany) have identified a moon orbiting 2007 OR10. They spotted it in Hubble Space Telescope images taken in September 2010 as part of a survey of trans-Neptunian objects. Marton announced the discovery this week at a joint meeting of the AAS’s Division for Planetary Sciences and the European Planetay Science Congress.

Although 2007 OR10 itself has been known for almost a decade, only recently have researchers realized that it’s surface is quite dark and therefore that it must be quite sizable, with an estimated diameter of 1,535 km (955 miles). This makes it the third-largest dwarf planet, after Pluto and Eris. It also ranks third for distance — 13 billion km or 87 astronomical units away — drifting among the stars of central Aquarius at a dim magnitude 21.

Of the eight largest Kuiper Belt objects, only Sedna has not yet been found to have a moon.

Did fueling procedures cause Falcon 9 launchpad explosion?

6:18 pm

This Wall Street Journal article today speculates that “problematic fueling procedures” might have caused the September 1 Falcon 9 launchpad explosion.

Company officials have said it is too early to arrive at definitive answers, though one person familiar with the investigation said initial concerns about potentially substandard welds have been relegated to a low priority. If testing bears out early findings focusing on problematic fueling practices instead of hardware flaws, SpaceX likely will avoid a major redesign effort or extensive quality-control checks that could drag on for months.

Caution must be exercised here. The article depends on unnamed sources, and does not provide any details describing how fueling procedures could have caused the explosion.
