Virgin Galactic signs deal for supersonic plane

6:18 pm

The competition heats up: Virgin Galactic has signed a deal with Boom, the start-up company trying to build the first commercial supersonic passenger jet since the Concorde.

Boom, which has spent the past three months participating in Y Combinator’s startup accelerator program in Silicon Valley, has inked a deal with Virgin. As part of the deal, Virgin has taken an option in Boom’s first 10 planes, while Virgin Galactic, the private space exploration company, will assist with manufacturing and testing through its manufacturing arm, The Spaceship Company.

I hope Boom is more successful than Virgin Galactic in getting its project off the ground. If not, than it will be a long time before we see this plane take off.

First Rocket Lab launch this year

6:13 pm

The competition heats up: The new launch company Rocket Lab has announced that it expects the inaugural launch of its Electron rocket to take place sometime in the middle of this year.

The company announced March 22 that it has completed qualification tests of the Rutherford engine, allowing it to be used in flights of the Electron vehicle. A video released by the company showed the engine firing on a test stand for more than two and a half minutes.

The first launch is planned for the middle of this year, company spokeswoman Catherine Moreau-Hammond said March 23, with the overall flight test program running through the second half of the year. Those launches are planned from a site the company is developing on New Zealand’s North Island.

This company is in direct competition with Virgin Galactic’s LauncherOne, and like everyone will likely be in operation first, beating Branson’s company despite starting almost a decade later.

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 founder of the Mars Society.

Saying “All Lives Matter” is now white supremacy

10:02 am

The coming dark age: A group of sixty professors at American University’s Washington College of Law have signed a letter claiming that to say “All lives matter” instead of “Black lives matter” is an example of “white supremacy.”

Dozens of professors from American University’s Washington College of Law (WCL) openly condemned an unknown student as a white supremacist for posting a sign with the catchphrase “All Lives Matter” on a faculty member’s door.

“The ‘All Lives Matter’ sign might seem to be a benign message with no ill intent, but it has become a rallying cry for many who espouse ideas of white supremacy and overt racism, as well as those who do not believe the laws should equally protect those who have a different skin color or religion,” the professors wrote in a statement to the WCL community.

For college professors to no longer recognize the plain meaning of words, and to instead assign a meaning of their own to those words, for their own political purposes, tells me that if I had a son or daughter attending this university I would pull them out immediately. Not only are students not being educated properly there, they are being taught nonsense and hate.

Another Rosetta close-up of Comet 67P/C-G

9:50 am

Close-up Comet 67P/C-G

Cool image time! As Rosetta completes a several weeks of in-close observations it took the above oblique view (cropped and reduced to show here) of Comet 67P/C-G. The image was taken from about 7.5 miles with a resolution of about 3 feet per pixel. It shows the Imhotep flat area with the large 80-foot-high Cheops boulder in the center. It is worthwhile to compare this image with one taken in January.. Though the angle is far different, you can recognize the same areas in Imhotep where some of the surface has apparently evaporated away.

What I especially like about today’s image is that it really gives one a feel for what it would be like to stand on the surface here. The light gravity allows some strange rock configurations, such as that giant weird balancing outcrop on the horizon. If you were standing in Imhotep that outcrop would hang above you threateningly.

The spacecraft is now moving away from the comet for the next few weeks

Following the brief encounter at these close distances, Rosetta is now heading out on an anti-sunward excursion to around 1000 km to investigate the comet’s wider coma, tail and plasma environment. Today, 24 March, Rosetta is already over 200 km away from the comet. The current plan is for Rosetta to make a 30 km zero phase flyby around 9 April, before entering back into closer bound orbits by 21 April.

New Horizons’ future research goals

9:15 am

On Monday at a planetary science conference Alan Stern, the project scientist for New Horizons, outlined the science goals in studying the Kuiper Belt should the spacecraft’s mission be extened through 2021.

The main goal will be the January 1, 2019 fly-by of Kuiper Belt object 2014 MU69, estimated to be between 12 to 24 miles across. However, the proposal also includes the following:

“In addition to making a close flyby of MU69, we’re also going to be close enough in range to study quite a number of other small KBOs, and some large ones that are on the Pluto scale,” Stern said. New Horizons will be able to study them in ways that could never be accomplished from Earth. The closeness of the spacecraft will enable high resolution observations, and the ability to look for satellites that cannot be seen from Earth observatories or with the Hubble Telescope.

“Because we are looking back on the rest of the solar system, at the Kuiper Belt and the Centaur Population,” Stern said, “we’re going to be able to study another 18 or 20 small bodies to determine whether or not the recently discovered rings around the centaur Chariklo are a common occurrence, or something anomalous. And I don’t know of any other way over the next several years, except through New Horizons, that we can develop a data set like that.”

What I find amazing is that it appears from Stern’s remarks that NASA has not yet approved this proposal. Before the team discovered 2014 MU69, I would have been more skeptical about extending the mission, but since they will be able to do a close fly-by of a type of object never before seen, and considering the time and cost it takes to get to the Kuiper Belt, it seems foolish now to not approve this mission extension.

House proposes killing Commerce Department

9:00 am

In a just released budget resolution, the House budget committee has proposed eliminating the Department of Commerce in an effort to cut costs.

The biggest potential shift from the status quo would be breaking up the $9 billion commerce department. DOC is one of the least-known, and most unloved, of all federal agencies. But it nonetheless oversees a huge scientific portfolio that includes the National Oceanic and Atmospheric Administration (NOAA), the National Institute of Standards and Technology (NIST), and the Census Bureau. Under the heading “options worthy of consideration,” the budget committee suggests moving NOAA to the Department of Interior, placing NIST within NSF, and assigning the Census Bureau, including the massive decennial census, to the Department of Labor’s Bureau of Labor Statistics. Another commerce agency, the U.S. Patent and Trademark Office, would become an independent agency.

The obvious goal would be to eliminate the expensive upper management positions at Commerce and thus reduce cost. Such changes however are going to face opposition in the privileged science community. While that community has been unable to sustain the growth of its funding in the past decade, it has successfully prevented the elimination of any program or any significant reduction in the science budgets. We shall see if that record will hold in the coming years, with the electorate appearing to steadily shift more and more to the right.

The article, by Science reporter Jeffrey Mervis, also included this wonderful example of yellow journalism:

The proposed budget resolution talks repeatedly of the need to reduce spending and, in particular, curb the clichéd “waste, fraud, and abuse” that is allegedly rampant across the federal government by killing duplicative or unnecessary programs. [emphasis mine]

I’ve noted Mervis’s agenda-driven writing in the past. In the sentence above he illustrates his unreliability as a reporter. For any educated journalist to consider waste and fraud in the federal government to be “alleged” is to be a person either with his head in the sand or having so strong a bias that he is intentionally misreporting the facts. Sadly, in the case of Mervis and many in today’s so-called elite intellectual community, I think it is both.

Nation’s largest health insurance company wants out of Obamacare

8:33 am

Note: This post was supposed to be published in November, 2015. I just discovered that it had not done so. Though late, the news it contains is still current and important, so I am publishing it now.

Finding out what’s in it: The nation’s largest health insurance company is considering pulling out of the Obamacare exchange because of cost and red ink.

The release added that, “UnitedHealthcare has pulled back on its marketing efforts for individual exchange products in 2016. The company is evaluating the viability of the insurance exchange product segment and will determine during the first half of 2016 to what extent it can continue to serve the public exchange markets in 2017.” The company said it expects “earnings pressure” of $425 million, which “is driven by projected losses on individual exchange-compliant products related to the 2015 and 2016 policy years.”

Insurers have had trouble signing up young and healthy individuals on the Obamacare exchanges, which is necessary to offset the costs of covering older and sicker enrollees. This has forced insurers to hike premiums, raise deductibles, and slash the number of doctors and hospitals offered on its plans. Meanwhile, the Obama administration has cut its enrollment expectations for 2016 to about half of what they were when the the legislation became law.

It appears that even if Congress does nothing, sometime around 2017 Obamacare will force the entire collapse in the health insurance industry. To stay in business under Obamacare, insurance companies have had to increase co-pays and deductibles so much there is increasingly little reason to have an insurance policy at all, especially since the premiums have also skyrocketed.

The biggest irony of all this is that all insurance is beginning to resemble those so-called “junk ” insurance policies that Obamacare banned, These were the inexpensive plans that provided few benefits except coverage for the costs coming from a catastrophic injury or sickness. Today, Obamacare is forcing all insurance to be like this, except that Obamacare has turned these once inexpensive junk policies into very expensive ones.

It’s the Beatles

6:01 pm

An evening pause: Broadcast on December 7, 1963 by the BBC, this excerpt from the 30 minute television show before 2,500 members of The Beatles’ Northern Area Fan Club gives us a glimpse into the craziness that heralded the Beatles arrival on the world scene. The clip includes the last third of the show.

Why do these teenage girls remind me of modern voters attending rallies for Donald Trump and Bernie Sanders?

An estimated $55 billion in Obamacare waste

9:31 am

Finding out what’s in it: Since its signing Obamacare has caused the government and public to waste approximately $55 billion.

Though most of that number, $45 billion, is an estimate of the amount of money businesses and people have been forced to spend filling out Obamacare paperwork and thus somewhat guesswork, the remaining $10 billion is based on hard data and real waste, such as handing out almost a billion in improper subsidies or spending $2 billion to construct a website that did not work.

But who’s counting? It is more important that we can go to bed at night knowing that the Democrats care about us, and will try anything, even if it is insane or completely stupid, to make us feel better about ourselves.

DOD opens ULA investigation

9:12 am

The deputy inspector general of the Defense Department has notified the Air Force that he is beginning an investigation into ULA and the DOD over their relationship and contract.

He also made it clear that the investigation was sparked by last week’s comments by a ULA executive who subsequently resigned.

This is all a game. The Air Force and ULA have been colluding for years to squeeze out any competition. There is no one in Washington who needs an investigation to find this out. The inspector general will issue a report, the Air Force will admit its error and promise to do better, and they will then try to have things continue as they have.

The one difference, however, will be that SpaceX will be there, providing real competition. Thus, what matters isn’t the investigation by the inspector general. What matters is the existence of a competing company willing to put cost pressure on ULA and the Air Force.

TMT leadership looks at alternatives to Hawaii

9:01 am

Though they have refused to comment publicly, the Facebook page for the Thirty Meter Telescope on Monday showed the telescope’s management visiting the Canary Islands, a potential alternative site to Hawaii.

Their Facebook post serves two purposes. It shows that they mean business when they say they must start considering abandoning Hawaii. It also might force the Hawaiian state government to stop dragging its feet in the permitting process that protesters have forced TMT to go through, a second time.

Court again rules against IRS and Justice Department

11:13 pm

Working for the Democratic Party: A federal appeals court has condemned the behavior of IRS and Department of Justice lawyers for a misuse of the law and demanded they begin cooperating with the court.

Tea party groups have been trying for years to get a full list of nonprofit groups that were targeted by the IRS, but the IRS had refused, saying that even the names of those who applied or were approved are considered secret taxpayer information. The IRS said section 6103 of the tax code prevented it from releasing that information.

Judge Kethledge, however, said that turned the law on its head. “Section 6103 was enacted to protect taxpayers from the IRS, not the IRS from taxpayers,” he wrote.

Edward Greim, a lawyer at Graves Garrett who is representing NorCal Patriots, said they should be able to get a better idea of the IRS‘ decision-making once they see the list of groups that was targeted. “What we’ll be able to see is how, starting in the spring of 2010, with the first one or two groups the IRS targeted, we’ll be able to see that number grow, and we’ll even be able to see at the tail end their possible covering up that conduct,” he said. He said they suspect the IRS, aware that the inspector general was looking into the tax agency’s behavior, began adding in other groups to try to muddle the perception that only conservatives were being targeted.

Atlas 5 launches Cygnus

11:04 pm

The competition heats up: A ULA Atlas 5 rocket tonight successfully placed an Orbital ATK Cygnus freighter into orbit to resupply ISS.

This was the second time an Atlas 5 put Cygnus into orbit. The next Cygnus flight will mark the return of Orbital’s Antares rocket.

This Cygnus capsule contains probably one of the more interesting engineering experiments flown by NASA in years. When it leaves ISS in about two months they will ignite a fire inside it to study the way fires spread and burn in weightlessness.

VA reinstates worker who committed armed robbery

10:11 pm

Our government at work: A VA worker has been reinstated with back pay after being fired for participating in an armed robbery.

It is worse than you think. The reason her union won her case was because the VA hadn’t fired other workers who had broken the law, so thus it was unfair to fire her as well.

A Department of Veterans Affairs employee in Puerto Rico was fired after being arrested for armed robbery, but her union quickly got her reinstated — despite a guilty plea — by pointing out that management’s labor relations negotiator is a registered sex offender, and the hospital’s director was once arrested and found with painkiller drugs…

Employees said the union demanded her job back and pointed out that Tito Santiago Martinez, the management-side labor relations specialist in Puerto Rico, who is in charge of dealing with the union and employee discipline, is a convicted sex offender. Martinez reportedly disclosed his conviction to the hospital and VA hired him anyway, reasoning that “there’s no children in [the hospital], so they figure I could not harm anyone here.”

The union’s position — that another employee committed a crime and got away with it, so this one should, too — has been upheld by the highest civil service rules arbiters, and has created a vicious Catch-22 where the department’s prior indefensible inaction against bad employees has handcuffed it from taking action now against other scofflaws.

And the intellectual elites in Washington wonder why people are angry and want to throw the bums out. In fact, that they remain clueless about this anger and continue to do nothing about this kind of obscene corruption in the government departments that they control is only more reason to throw them out. Maybe we should even consider bringing back that old American custom: to tar and feather them and ride them out of town on a rail.

Near disaster for ExoMars

6:22 pm

The Russian jinx for going to Mars might not be over yet: New data suggests that the Briz-M upper stage to the Proton rocket exploded shortly after it has propelled ExoMars on its way to Mars and then separated from it.

There appears to be a cloud of debris near the probe, thought to have been caused when the Briz-M stage was to fire its rockets one last time to take it away from ExoMars as well as prevent it from following it to Mars. Instead, it is thought (though not confirmed) that the stage blew up at that moment.

Though so far ExoMars appears to be functioning properly, but they have not yet activated all of its most sensitive instruments. Only when they turn them on in April will we find out if they were damaged in any way by the Briz-M failure.

Emory University takes action to stop free speech

4:26 pm

The coming dark age: Students at Emory University are protesting the horror of having to see the words “Vote Trump” and “Trump 2016” written in chalk throughout the campus last week, and the university president, in total sympathy with these horrified students, has agreed to take quick action to prevent such horrors in the future.

The letter the university president wrote is worth reading in its entirety, as it illustrates forcefully the uselessness of today’s academic elite and the worthlessness of a liberal arts education at most of today’s colleges. Here is just one quote:

Yesterday I received a visit from 40 to 50 student protesters upset by the unexpected chalkings on campus sidewalks and some buildings yesterday morning, in this case referencing Donald Trump. The students shared with me their concern that these messages were meant to intimidate rather than merely to advocate for a particular candidate, having appeared outside of the context of a Georgia election or campus campaign activity. During our conversation, they voiced their genuine concern and pain in the face of this perceived intimidation.

After meeting with our students, I cannot dismiss their expression of feelings and concern as motivated only by political preference or over-sensitivity. Instead, the students with whom I spoke heard a message, not about political process or candidate choice, but instead about values regarding diversity and respect that clash with Emory’s own.

In other words, these poor students might have to admit that there is at least one person on their campus who disagrees with them and supports Donald Trump. We can’t have that! The president then goes on to outline some vague actions he is going to take to prevent such dissent from happening again. These students mustn’t be subjected to a free and open debate. It might cause them to think!

In related news, a Hispanic businesswoman who expressed Latino support for Donald Trump at one of his rallies is now being threatened and harassed at her business.

New close-up of Occator Crater’s spots

1:57 pm

Occator Crater central spot

The Dawn science team have released new images taken from the spacecraft’s low orbit observations, including a close-up of the central white spot at Occator Crater, the brightest spot on Ceres.

The image on the right is a cropped though full resolution version of the full image. I have reduced it only slightly. As they note,

Occator Crater, measuring 57 miles (92 kilometers) across and 2.5 miles (4 kilometers) deep, contains the brightest area on Ceres, the dwarf planet that Dawn has explored since early 2015. The latest images, taken from 240 miles (385 kilometers) above the surface of Ceres, reveal a dome in a smooth-walled pit in the bright center of the crater. Numerous linear features and fractures crisscross the top and flanks of this dome. Prominent fractures also surround the dome and run through smaller, bright regions found within the crater.

“We don’t need another lecture about Islamophobia.”

9:45 am

Mohammad the bomber

The religion of peace strikes again: Thirty-four are dead and almost 200 injured in suicide attacks in Belgium today.

ISIS has claimed credit for the attacks.

I think the reactions of our politicians here is of some significance, as by contrasting them we can learn a bit about each. Obama inserted a short pro-forma statement of sympathy during his prepared remarks at the start of a press conference in Cuba, then appeared to forget about the entire horrific attack. Donald Trump called for greater border security and a renewed consideration of the use of waterboarding to obtain information from captured terrorists. Hillary Clinton (at the previous link) expressed some incoherent blather about following “our values”.

Ted Cruz possibly spoke with the most clarity.

“Today’s attacks in Brussels underscores this is a war,” Cruz said. “This is not a lone war. ISIS has declared jihad. It is way past time we have a president who will acknowledge this evil and will call it by it’s name and use the full force and fury to defeat ISIS,” he continued. “Until they are defeated, these attacks will continue. Their target is each and every one of us.”

Cruz, one of five remaining presidential candidates, urged America needs a leader who is not afraid to speak about terrorism in bold terms. “We need a president who sets aside political correctness,” Cruz insisted. “We don’t need another lecture about Islamophobia.”

Cruz also criticized Trump’s proposal yesterday that we pull back from NATO.

I leave it to you to decide who appears to have the greatest grasp of the situation. And if you think I am spinning this to favor Cruz, go to the links and get a closer look at the other reactions. Note for example that, other than a twitter comment, I could not even find a story that specifically discussed Hillary Clinton’s reaction.

Update: I have added the cartoon showing Mohammad with a bomb in his turban because I think the response to these thugs has to be to defy them as blatantly as possible. I need to remember to do this more often.

Does captivity hurt or help killer whales? Scientists disagree

9:21 am

The uncertainty of science: Two different science research teams strongly disagree about the positive or negative effects of living in captivity for killer whales.

In a decision hailed by animal-rights groups, the US marine-park company SeaWorld Entertainment announced last week that it will no longer breed killer whales. But whether captivity harms the planet’s biggest predator is an area of active scientific debate.

The latest arguments centre on two 2015 studies that drew dramatically different conclusions about the lifespans of captive killer whales (Orcinus orca), relative to those of wild populations. Although many factors affect well-being, an apparent discrepancy between the survival of captive and wild animals has long been cited by activists as evidence of the poor welfare of captive killer whales.

One of the studies is authored by a team largely made up of researchers at SeaWorld, which is headquartered in Orlando, Florida, and owns several animal parks that keep killer whales; the other is by two former killer-whale trainers at the company who feature in the 2013 documentary film Blackfish, which is critical of SeaWorld. In letters published last week, authors from each paper accuse the others of cherry-picking data to support positions on whether the animals should be captive — charges that each team in turn rejects.

Obviously, each science team has its own agendas. The result unfortunately is that the science is cloudy and unclear.

Fuel for Russia’s nuclear space engine

9:14 am

The competition heats up: According to Russian press sources, the first fuel for that country’s nuclear space engine project has now been delivered to Rosatom, Russia’s nuclear energy corporation.

The article is very unclear whether this space engine is a nuclear power plant similar to those used by NASA’s deep space Voyager, Pioneer, and Cassini probes, or whether it is a real nuclear-powered engine designed to provide thrust. Russia has never launched a probe with the former, so that would be an advancement for them, but it would not be a game-changer in the exploration of the solar system. If the latter, however, it will give them the capability no one else has to travel quickly and more efficiently to other worlds.

Based on a careful rereading of the article, I suspect the former.

A new gravity map of Mars

9:06 am

Using data from three orbiting NASA spacecraft scientists have created a new gravity map of Mars, showing the subtle variations in its gravitational field due to density differences within the planet.

The improved resolution of the new gravity map suggests a new explanation for how some features formed across the boundary that divides the relatively smooth northern lowlands from heavily cratered southern highlands. Also, the team confirmed that Mars has a liquid outer core of molten rock by analyzing tides in the Martian crust and mantle caused by the gravitational pull of the sun and the two moons of Mars. Finally, by observing how Mars’ gravity changed over 11 years – the period of an entire cycle of solar activity — the team inferred the massive amount of carbon dioxide that freezes out of the atmosphere onto a Martian polar ice cap when it experiences winter. They also observed how that mass moves between the south pole and the north pole with the change of season in each hemisphere.

Vostochny begins practicing launch procedures

8:59 am

The competition heats up: Dress rehearsals have begun for the first Soyuz rocket launch at Russia’s new spaceport Vostochny, scheduled sometime this spring.

They have not announced an official launch date yet.

If all tests go as scheduled, the launch vehicle will be removed from the launch pad on March 25 and returned to its processing facility for the final assembly with its payloads, including Lomonosov, Aist-2D and Kontakt-Nanosputnik satellites, which will be delivered into orbit during the first mission from Vostochny. The State Commission overseeing the launch will be making decision on the date of the first liftoff based on the results of the tests, the readiness of the launch facilities and the completion of safety measures for the launch personnel, Roskosmos said.

United Arab Emirates teams up with Japan

8:49 am

The new colonial movement: The United Arab Emirates Space Agency (UAESA) has signed a cooperative agreement with Japan’s space agency JAXA.

The details are slim, but I suspect it is similar to the recent UAE/India deal and involves the UAE providing some of its oil money in exchange for getting some of Japan’s technical help.

Update: My suspicions were correct. UAESA has purchased launch services from Japan Mitsubishi for its Mars mission, dubbed Hope, scheduled for launch in 2020.

New supersonic passenger plane coming?

8:43 am

Boom! A new aviation company thinks it can develop a new supersonic passenger plane with ticket prices far less than the Concorde’s.

If you’re ever stuck on a plane pining for the glory days of air travel, hop on YouTube and search for “the Concorde.” Among the results are a bunch of firsthand accounts of people sipping Champagne and scarfing down caviar on one of the bygone supersonic jets while they travel at 1,300 miles an hour. Try to appreciate the joy on their faces, or at least remember that they paid as much as $20,000 round trip, while you’re crammed into a middle seat with nothing but a dollop of hummus and a few overpriced crackers to get you through the next few hours.

Or perhaps find some solace in this: A Denver startup called Boom Technology plans to bring supersonic passenger travel back, and to bring it to the masses … ish. While the finished product is years away, on March 23, Boom will unveil its design for a 40-seat plane that can fly 1,451 mph (Mach 2.2). At that speed, a New York-to-London flight would take about 3 hours and 24 minutes. Blake Scholl, Boom’s founder and chief executive officer, says round-trip tickets will cost $5,000. “The idea is for a plane that goes faster than any other passenger plane built before, but for the same price as business class,” he says.

The project is barely past the PowerPoint stage, so color me skeptical. Nonetheless, I also believe it is possible, especially when I noticed in reading the article the similarities between between this company’s founder and that of SpaceX’s.
