Oh no! Trump’s wall to block butterflies!

3:05 pm

The bankruptcy of our modern intellectual culture, including its increasingly insane hatred of anything-Trump, might best be illustrated by this story today in the San-Antonio Express-News: First signs of border wall construction spotted at National Butterfly Center.

The full article might be behind a paywall, but let me quote from the teaser text:

A gigantic yellow earth mover arrived on National Butterfly Center land Sunday afternoon, the first sign of the beginnings of border wall construction in that protected habitat.

The steel-and-concrete levee wall is expected to slice through the center, placing 70 of the sanctuary’s 100 acres of land south of it.

Oh my! Isn’t Trump evil! This wall will prevent the illegal immigration of butterflies!

First, any sane rational person will immediately recognize that putting a wall through a butterfly sanctuary is going to do nothing to interfere with the butterflies that use that sanctuary. Butterflies are smarter than the average news reporter, and know that they can simply fly over a wall.

Second, the use of hyperbole in the article’s text reveals the reporter’s bias. The wall will “slice” through the center. And the earth mover is “gigantic” (which anyone can clearly see it is not, simply by looking at the picture at the top of the story). The writer used these absurd emotionally charged words to accentuate the disaster of this “slicing” by the “gigantic” earth mover.

Finally, the article’s timing also reveals the author’s biases. She is acting as a PR agent for Democratic congressman Henry Cuellar (D-Texas), who last week introduced amendments to the Democratic house budget bill that would have forbid any wall from being built inside or around this or other Texas border parks.

Cuellar’s proposal, however, is clearly not meant to protect the park, but to prevent the border patrol from protecting the U.S. border, as it is constitutionally required to do. It might make sense to require any border wall to skirt the southern edge of these parks in order to prevent harm to the parks, but Cuellar’s proposal specifically outlaws any wall “within, south of, or north of the National Butterfly Center,” essentially making this park a guaranteed gap in the wall which in turn could very well attract illegals in great numbers. Based on what I have seen of illegal trash in federal lands here in southern Arizona, that intrusion would do far more harm to the park than a simple wall.

Strange fernlike ridges on Mars

1:44 pm

Fernlike ridges on Mars

Cool image time! The two images on the right, cropped, rotated, and reduced in resolution to post here, were both taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO). To see the full resolution version of each, go to the 2009 and 2018 releases.

The 2009 release was a captioned release, whereby scientist Alfred McEwen of the science team provided his explanation of these strange features.

The dark branched features in the floor of Antoniadi Crater look like giant ferns, or fern casts. However, these ferns would be several miles in size and are composed of rough rocky materials.

A more likely hypothesis is that this represents a channel network that now stands in inverted relief. The channels may have been lined or filled by indurated materials, making the channel fill more resistant to erosion by the wind than surrounding materials. After probably billions of years of wind erosion the resistant channels are now relatively high-standing. The material between the branched ridges has a fracture pattern and color similar to deposits elsewhere on Mars that are known to be rich in hydrated minerals such as clays.

These strange fernlike features do not appear to be very common on Mars. In fact, I suspect that while Mars does have many inverted channels like this, the fernlike nature of these particular channels is unique on Mars. They are located on the floor of Antoniadi Crater, a large 240-mile-wide very ancient and eroded crater located in the Martian southern highlands but near the edge down to the northern lowlands.

In seeing the new 2018 image, I was immediately compelled to place it side by side with 2009 image to see if anything had changed in the ensuring near-decade. There are color differences, but I suspect these are mostly caused by different lighting conditions or post-processing differences. Still, the dark center to the crater in the upper left of both images suggests a change in the dust dunes there, with the possibility that some of the dust has been blown from the crater over time. Also, you can see two horizontal tracks cutting across the center of the 2018 image, which I would guess are dust devil tracks, with one more pronounced.

I can imagine some planetary geologists have spent the last few months, since the second image was taken, pouring over both photographs, and have might even located other interesting changes. And if they find no significant changes, that in itself is revealing, as it gives us a sense of the pace at which the Martian surfaces evolves.

InSight’s seismometer now fully operational

1:06 pm

The InSight science team has completed the deployment of the spacecraft’s seismometer by the placement of its protective domed shield over it.

The Wind and Thermal Shield helps protect the supersensitive instrument from being shaken by passing winds, which can add “noise” to its data. The dome’s aerodynamic shape causes the wind to press it toward the planet’s surface, ensuring it won’t flip over. A skirt made of chain mail and thermal blankets rings the bottom, allowing it to settle easily over any rocks, though there are few at InSight’s location.

The shield also helps protect the instrument from temperature changes.

With this deployment completed they will next deploy the heat flow package to the surface, where it will begin to drill its probe sixteen feet into the ground.

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.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

We are all fundamentalist now

4:15 pm

Link here. This is a superb essay about the strange similarities between the motives and aims of both fundamental Christians and the modern leftist social justice warriors.

For me the heart of the essay is this quote:

The modern campus culture is a religious culture, but it’s a religion without God, and consequently it is a religion without grace. Many students would probably hear my story about growing up in conservative Evangelicalism and conclude that I have been violently oppressed. What if, though, we have more in common than they think? What if SJWism and religious fundamentalism are both expressions of a dissatisfaction with the decadence of modernity: its mindless consumerism, its divorce of virtue from culture, and its kowtowing to profit and power?

The crucial difference, of course, is that Christians and many other religious conservatives have a coherent theological narrative. Because we retain the language of sin and guilt, we have the categories necessary to confront cultural decadence with more than outrage. The militant, shame-them-out-of-existence character of much social-justice activism is a frustrated attempt to articulate truths that students indoctrinated in secularism feel intuitively but deny intellectually.

To my mind, as a secular humanist, the issue isn’t the lack of God, but the unwillingness of the leftist fundamentals of academia and the leftist social justice movement to admit to the wisdom of religious thought on the subject of right and wrong. Religions worldwide are all attempts to articulate in detail the human framework for good behavior while outlining what behaviors lead to disaster and injustice. Our modern bankrupt intellectual culture that now dominates academia has rejected those attempts, despite their depth and complex, intellectual, and very long-lived research into the subject. Thus we have a shallow fundamentalist culture in modern academia, longing for justice and righteous behavior, with little framework or knowledge to find it.

The result? Fascism, illustrated by a rising string of intolerant and shallow attacks on anyone who disagrees with them.

Unmanned test flight of manned Dragon delayed again?

10:36 am

SpaceX has applied for a new launch license from the FAA for its unmanned test flight of its manned Dragion capsule that sets the launch date as no earlier than March 2nd.

This does not necessarily mean the launch is delayed until then. As noted by commenter Kirk Hilliard here at Behind the Black, “their previous license was valid through 1 March, so they may just be covering their bases here while still planning on launching under the authority of their previous license.”

Regardless, I have seen nothing to change my opinion about the cause of these delays: the NASA bureaucracy. SpaceX has been ready to do this launch since December. It has already done two successful launch rehearsals, one in which they did a successful static fire test, as is standard for the company. Both illustrate their readiness. The launch would use their leased launchpad using their launch crew. There has been no indication of any technical reason for the delays, other than a demand that SpaceX complete paperwork for NASA and the government shutdown (which has not prevented other launches from government facilities).

ULA gets launch contract for Lucy asteroid mission

10:21 am

Capitalism in space: NASA has awarded ULA a $145 million contract to launch the Lucy asteroid mission on its Atlas 5 rocket.

The price is high for such a launch in today’s market, and is even higher than the cost of some recent military launches, which routinely tack on extra requirements that cause the price to rise. I wonder why. Is it because NASA doesn’t care how much it spends? Or is there a political component here, providing a contract to a company that is having trouble winning contracts in the private sector because their price is too high?

It could be that the mission requires things from the launch that add to the cost. The press release mentions that it “includes the launch service and other mission related costs” but does not specify what they are.

We are one step closer to the first replicator

10:01 am

Scientists have developed and tested a 3D printing technique that quickly creates entire objects as a unit, rather than building them by layers.

Here’s how it works. First, the researchers use a computer-controlled digital light projector to cast a series of 2D images through a rotating vial containing a photosensitive gel. As the vial rotates, photons entering from different angles meet at selected spots in the gel. Where they meet, their combined energy solidifies the gel. Where that meetup doesn’t occur, the photons simply pass through without altering the photosensitive material.

The approach is fast, able to create complex objects, such as a centimeter-size copy of Rodin’s famous sculpture of The Thinker in just minutes, the researchers report today in Science. It can also make 3D plastic parts around existing objects, such as a plastic handle around a metallic screwdriver shaft. The approach could also be useful for encapsulating sensitive electronics, the authors write.

If you go to the supplementary material for their paper, you can watch several videos showing this process at work, creating both the Thinker as well as a ball in a cage.

I think I have reported on this process previously, but this new paper shows a significant advance. Nonetheless, this engineering here is still very preliminary.

Local downrange homeowners have announced their opposition to Georgia spaceport

9:48 am

Capitalism in space: A local homeowners association today announced its opposition to the proposed commercial spaceport in Camden County, Georgia.

Cumberland and Little Cumberland Islands have just become the first communities in America to be directly downrange from a vertical launch spaceport awaiting license approval from the FAA. More than sixty private homes lie in the path of rockets that Camden County commissioners hope someday to launch.

In the history of U.S. space flight, neither NASA nor the FAA have permitted a vertical launch over private homes or people directly downrange. The risk to people and property from an exploding rocket is too great.

If they are truly downrange from the launchpads, I would say their objection is 100% valid, and the spaceport application should be denied. And I suspect this is true, since the county had an analysis done on this subject but has refused to release it.

Because of Russian violations, U.S. withdraws from nuclear arms treaty

9:42 am

The United States announced today that it is withdrawing from the 1987 Intermediate-Range Nuclear Forces (INF) Treaty because of numerous and long-standing violations by Russia.

[Secretary of State Mike] Pompeo explained that Russia has been violating the treaty for years, and despite those violations, the U.S. has attempted to maintain the agreement. “To this day, Russia remains in material breach of its treaty obligations not to produce, possess, or flight test a ground-launched intermediate cruise missile system with a range between 500 and 5500 kilometers,” Pompeo explained. “We have raised Russia’s noncompliance with Russian officials, including at the highest levels of government, more than 30 times, yet Russia continues to deny that its missile system is noncompliant and violates the treaty,” Pompeo said.

Pompeo said Russia’s violation of the treaty has compromised U.S. security interests. “It’s our duty to respond appropriately,” Pompeo said. “When an agreement is so brazenly disregarded, and our security is so openly threatened, we must respond.”

The announcement comes one day ahead of the 60-day deadline the U.S. gave Russia to return to compliance with the treaty.

The treaty calls for a six month period following this announcement for the withdrawal to be completed.

Though the announcement mentions a specific “a prohibited missile system,” it does not say what that missile system is. I suspect it might be the hypersonic missile the Russians have tested and say they will deploy this year.

Global warming must be happening! A politician declares it!

2:32 pm

Stop the presses! Expert climate scientist and former New York City mayor Michael Bloomberg has used his extensive scientific research to determine, without a doubt, that the polar vortex that is presently freezing most of the country in record cold temperatures is unequivocally the result of global warming!

“The science is clear: Climate change makes extreme weather more frequent and more intense,” tweeted Mr. Bloomberg. “Americans are seeing this first hand from wildfires to hurricanes to the #PolarVortex in the Midwest. We need a climate champion in the WH who can lead us forward.”

I always go to politicians to get my science information. Don’t you? And in doing so, I immediately dismiss other details, such as the fact that the recent wildfires in California is mostly due to bad policy in clearing brush by California and the federal government, that there is no evidence of an increase hurricanes activity, and that back in the 1970s scientists linked the polar vortex to global cooling.

None of that actual data matters. A politician has spoken, and his word is always reliable. Moreover, this is a liberal politician, whose word is even more reliable, because he cares.

Finally, and maybe most important, he did this on twitter, that icon of thoughtful analysis and deep complex thought.

We should immediately shut down all fossil fuel operations, even if it means there will be no way to heat homes across most of the country and people will freeze to death. The world is being destroyed by those fuels, and we must save it!

The base of Mt Sharp is less compacted than expected

2:06 pm

The uncertainty of science: Using data from Curiosity in Gale Crater on Mars, scientists have found that the material making up the lower layers of Mount Sharp is less compacted that they would have expected.

Scientists still aren’t sure how this mountain grew inside of the crater, which has been a longstanding mystery.

One idea is that sediment once filled Gale Crater and was then worn away by millions of years of wind and erosion, excavating the mountain. However, if the crater had been filled to the brim, the material on the bottom, which now makes up the crater’s surface, would have been pressed down. But the new Science paper suggests Mount Sharp’s lower layers have much less compacted than this theory predicts, reigniting the debate about how full the crater once was.

“The lower levels of Mount Sharp are surprisingly porous,” said lead author Kevin Lewis of Johns Hopkins University. “We know the bottom layers of the mountain were buried over time. That compacts them, making them denser. But this finding suggests they weren’t buried by as much material as we thought.”

I can’t help wonder whether we don’t yet really understand the influence of Mars’ lower gravity on geology, and that might explain the porosity.

China’s unsupervised radio antenna in Argentina

12:01 pm

A Chinese invasion? A Chinese radio antenna in Argentina, initially proposed as a communications facility for use with China’s space program, operates without any supervision by the Argentinian government and appears to have military links.

Though U.S. government officials are pushing the idea that this facility is being used by China to eavesdrop on foreign satellites, and though China’s space program is without doubt a major arm of its military, I doubt the radio antenna is being put to military use. As the story notes

Tony Beasley, director of the U.S. National Radio Astronomy Observatory, said the station could, in theory, “listen” to other governments’ satellites, potentially picking up sensitive data. But that kind of listening could be done with far less sophisticated equipment. “Anyone can do that. I can do that with a dish in my back yard, basically,” Beasley said. “I don’t know that there’s anything particularly sinister or troubling about any part of China’s space radio network in Argentina.”

It was installed to support China’s effort to send spacecraft to the Moon and Mars, and that is likely its main purpose. China does not wish to be dependent on the U.S.’s Deep Space Network for such interplanetary communications. This facility helps make that independence possible.

At the same time, the fact that China has been allowed to establish a remote facility in another country and operate it with no oversight is definitely an issue of concern. Essentially, China has obtained control over a piece of Argentinian territory, and unless the Argentine government takes action, China can do whatever it wants there. While the antenna itself might not be an issue, the facility itself is.
