15 absurd over-reactions to Trump’s withdrawal from climate treaty

4:49 pm

Link here. Though Trump’s rejection of the climate deal is only tangentially related to the federal budget, it definitely has caused a lot of pigs to squeal. I especially like #13 from the leftwing American Civil Liberties Union, because it encompasses every absurd aspect of the modern left’s methods of debate:

Pulling out of the Paris Agreement would be a massive step back for racial justice, and an assault on communities of color across the U.S. — ACLU National (@ACLU) June 1, 2017

Read them all. And remember that these reactions came only an hour or so after Trump made his announcement. Expect even more silliness from the left in the days to come.

VSS Unity completes fifth glide flight

4:30 pm

Virgin Galactic’s new suborbital ship, VSS Unity, successfully made its fifth unpowered glide test flight today.

VSS Unity’s glide flights have gone well, and as a result, Virgin Galactic is getting ready to transition to the next part of the test campaign, company representatives said. “To that end, as we analyze the data from today’s flight, we will be moving into a period of ground-based activity focused on preparation for fueled, and then powered, flights,” they wrote in the description.

They provided no indication of exactly when those next flights will occur, which considering the company’s past record of failed predictions, is definitely a good thing.

Trump exits Paris climate agreement

1:39 pm

As he had promised during the campaign, President Trump today announced that he was withdrawing the United States from the Paris climate treaty that Obama had agreed to (but was never ratified by the Senate).

More here.

Despite Trump’s moderate liberal leanings on many issues (budgets, healthcare), it does appear that when it comes to the environmental movement’s corruption of science and overuse of regulation he is quite willing to do things that will upset the elitist ruling class that has done such a bad job of ruling for the past two decades.

Cumulative data from Curiosity shows Gale Crater lake stratified

12:22 pm

The cumulative data from Curiosity since its arrival on Mars three and a half years ago shows that the lake that once filled Gale Crater lake had had a stratified chemical make-up.

Previous work had revealed the presence of a lake more than three billion years ago in Mars’ Gale Crater. This study defines the chemical conditions that existed in the lake and uses Curiosity’s powerful payload to determine that the lake was stratified. Stratified bodies of water exhibit sharp chemical or physical differences between deep water and shallow water. In Gale’s lake, the shallow water was richer in oxidants than deeper water was.

“These were very different, co-existing environments in the same lake,” said Joel Hurowitz of Stony Brook University, Stony Brook, New York, lead author of a report of the findings in the June 2 edition of the journal Science. “This type of oxidant stratification is a common feature of lakes on Earth, and now we’ve found it on Mars. The diversity of environments in this Martian lake would have provided multiple opportunities for different types of microbes to survive, including those that thrive in oxidant-rich conditions, those that thrive in oxidant-poor conditions, and those that inhabit the interface between those settings.”

While what Hurowitz says above is true, remember that this discovery provides zero evidence of past life on Mars. All it has done is teach us something about the different conditions in the lake at different depths.

Trump to keep U.S. embassy in Tel Aviv

9:08 am

President Trump today signed a waiver allowing him to keep the U.S. Israeli embassy in Tel Aviv, rather than moving to Jerusalem as he promised repeatedly on the campaign trail.

This is not the most important political story of the day, but it illustrates what we can expect from Trump. In the end, he backs down under pressure from the Washington elitist community. For example, even though his proposed federal budget suggested a willingness to cut the deficit and eliminate whole agencies, I have doubts he will succeed in getting Congress to agree to any of those cuts.

This is also why I have not yet posted on the various rumors claiming that he plans to exit the Paris climate treaty. Until I actually see him do it, I do not believe it.

Rat sperm exposed to weightlessness still produces healthy rats

8:46 am

An experiment that flew on ISS has found that rat sperm exposed to weightlessness and space radiation and then used on Earth to fertilize eggs still produce healthy rats.

The first issue for the researchers was how best to get the sperm up there. They decided to have the samples freeze-dried, just like instant coffee. This meant the sperm weighed almost nothing and could be kept at room temperature, ideal for travel on a rocket, or on a distant planet. The mouse sperm then spent 288 days on the ISS before coming back to Earth to be compared with fresh sperm from the same mice.

First, the scientists analysed how space travel affected the integrity of the DNA within the sperm. We know that high levels of fragmentation of sperm DNA are associated with male infertility. As expected, the scientists discovered that the space sperm had higher amounts of fragmented DNA than the sperm which had stayed on Earth. However, when used to fertilise a mouse egg, the space sperm resulted in a similar number of healthy embryos being generated – and these offspring had the ability to develop into normal, fertile adult mice. A final test the researchers did was to compare the patterns of genes being expressed within the brains of the adult mice. Here, the researchers saw no overall differences and concluded the space sperm was equally capable of generating offspring.

Obviously, this result is encouraging, but we are still a long way from nonchalantly letting women get pregnant and give birth in space. The risks on the child remain too great and are unknown.

In fact, I suspect the first time a child is born and raised in space will be an event that is unplanned.

Russia moves to reduce launch costs with new rocket

8:37 am

The head of Roscosmos said today that they are pushing to accelerate the development of a new rocket, dubbed Phoenix, that will reduce launch costs by 20%, lowering the launch price per launch to $55 million.

I have been reading stories like this, about a new wonderful Russian rocket or spacecraft, for decades. First there was Clipper. Then there was Angara, repeatedly. Recently they have been talking up a new manned capsule and cargo ship. Along the way were a number of other forgotten proposals that would revolutionize space travel. None of these proposals however have ever seen the light of day, though Angara has completed two test flights.

In the past, Russia was not under any competitive pressure. They could undercut the launch price of every other rocket company in the world, without doing anything. Now, they face stiff competition that is only going to get stiffer. They need to produce, or they will be out of the game entirely.

The big question is whether they can, as a nationalized space industry run by a government that is rampant with corruption.

LIGO detects its third gravitational wave

8:22 am

LIGO scientists today revealed that the detector had spotted its third gravitational wave in January.

Researchers estimate that the bodies in the latest collision were slightly lighter than those in the first event: one had the mass of 31 Suns and the other 19. (The black holes in the second discovery were even more lightweight, at 14 and 8 solar masses.) But the latest merger is the most distant detected so far. The gravitational waves it produced took somewhere between 1.6 billion and 4.3 billion years to reach Earth — most probably around 2.8 billion years.

This new field of astronomy should get even more interesting in the next year or two, as new detectors come on line in Italy and Japan.

Frost on the Moon?

10:37 pm

A new analysis of Lunar Reconnaissance Orbiter data suggests that the coldest spots at the Moon’s south pole are also its brightest, even though they are generally in shadow, suggesting that the surface there might have a thin layer of water frost.

These are also the areas where hydrogen has been detected, which strengthens the theory that this is water.

However, the result is not a positive one for future colonists as it suggests that the amount of water on the Moon is far less than hoped. First, there is this:

The icy deposits appear to be patchy and thin, and it’s possible that they are mixed in with the surface layer of soil, dust and small rocks called the regolith. The researchers say they are not seeing expanses of ice similar to a frozen pond or skating rink. Instead, they are seeing signs of surface frost.

Second, they have not detected this same pattern at the north pole, which strongly suggests that the permanently shadowed areas there do not even have frost.

Overall, this result suggests that the Moon might have water on its surface, but not in great quantities.

NASA names next solar mission after pioneer solar scientist Eugene Parker

10:31 pm

NASA has named its next solar mission, which will fly closer to the Sun than any previous mission, after pioneer solar scientist Eugene Parker, who in the 1950s predicted the existence of the solar wind.

The new moniker honors pioneering University of Chicago astrophysicist Eugene Parker, who predicted the existence of the solar wind — the stream of charged particles flowing constantly from the sun — back in 1958. [Solar Quiz: How Well Do You Know Our Sun?]

NASA has named about 20 space missions after people; the Hubble Space Telescope is perhaps the most famous example. But the 89-year-old Parker is the first researcher to be celebrated in this manner while still alive, agency officials said.

Parker deserves it, for sure, and it is really nice to honor him while he is still alive to appreciate it.

The spacecraft is scheduled to launch at the end of July.

Stratolaunch unveils its giant mother ship

10:27 pm

Capitalism in space: Stratolaunch today finally revealed the giant airplane, the largest ever built, that it wants to use as a first stage for launching satellites cheaply into space.

From their webpage:

Over the past few weeks, we have removed the fabrication infrastructure, including the three-story scaffolding surrounding the aircraft, and rested the aircraft’s full weight on its 28 wheels for the first time. This was a crucial step in preparing the aircraft for ground testing, engine runs, taxi tests, and ultimately first flight.

Once we achieved weight-on-wheels, it enabled us to weigh the Stratolaunch aircraft for the first time, coming in at approximately 500,000 lbs. That may sound heavy, but remember that the Stratolaunch aircraft is the world’s largest plane by wingspan, measuring 385 ft. – by comparison, a National Football League field spans only 360 ft. The aircraft is 238 ft. from nose to tail and stands 50 ft. tall from the ground to the top of the vertical tail.

The Stratolaunch aircraft is designed for a max takeoff weight of 1,300,000 lbs., meaning it’s capable of carrying payloads up to approximately 550,000 lbs. As we announced last fall , we will initially launch a single Orbital ATK Pegasus XL vehicle with the capability to launch up to three Pegasus vehicles in a single sortie mission. We have already started preparations for launch vehicle delivery to our Mojave facilities. We’re actively exploring a broad spectrum of launch vehicles that will enable us to provide more flexibility to customers.

They plan to do ground tests throughout this year, aiming for a first flight test in 2019.

Santo & Johnny – Sleep Walk

6:01 pm

An evening pause: The song should immediately be familiar, though I doubt most people today will know of the performers who wrote it.

Hat tip Jim Mallamace, who writes, “This performance is from 1959, an era when performers wore ties to show respect to their audience. One must wonder how performers show respect to their audience, these days–or even if it’s an issue.”

If TMT moves from Hawaii Canada might exit partnership

11:32 am

The possibility that the Thirty Meter Telescope might be forced to move from Hawaii to the Canary Islands because of political opposition in Hawaii has Canadian scientists considering leaving the partnership.

The mega-telescope is “a critical component of the Canadian astronomical landscape,” says Michael Balogh, an astronomer at the University of Waterloo in Ontario. The country — one of six major international partners — has committed CAN$243 million (US$180 million) to the project. “If we have to move, it’s effectively a de-scope in the project,” says Balogh.

The back-up site, Roque de los Muchachos in La Palma, the Canary Islands, is lower in elevation than Mauna Kea, and its skies are more turbulent than those above the Hawaii mountain. That means that observing conditions are not quite as good; in particular, the extra atmosphere above La Palma interferes with much of the observing in mid-infrared wavelengths of light, the sweet spot for looking at exoplanet atmospheres.

If Canada leaves, there is a chance that the entire TMT partnership might fall apart.

Washington State legislators move to defund Evergreen State College

10:36 am

Couldn’t happen soon enough! Republican elected officials plan to introduce legislation this week that would strip funding from Evergreen State College, where mobs of leftist demonstrators have taken over the campus and threatened anyone who disagrees with them with violence, all with the tacit approval of the college’s administration.

The bill, spearheaded by Republican State Representative Matt Manweller, will be introduced alongside a letter to the state Human Rights Commission requesting an investigation into potential civil rights violations on campus surrounding the incident. Manweller and his colleagues are also discussing the possibility of revoking $24,000,000 in annual funding to Evergreen State College, but pledge that all students on campus will remain eligible for full financial aid from the state, should the bill become law. …

Manweller made clear that he places the blame for Evergreen’s current situation squarely on the shoulders of administrators, arguing that they created the conditions for controversy through their unquestioning embrace of social justice and failure to condemn the excesses of student protesters. “It is incredibly frightening that the administration at Evergreen would tacitly support Brown-shirt tactics we have not seen since 1930s Germany. That they would allow students to threaten professors and other students based on their race is simply horrifying,” Manweller continued. “The administration bears direct responsibility for this situation. They hired the professors who have elevated the pseudo-science of ‘social justice’ to a religious movement. Now all dissent is crushed by threats of violence or actual violence.”

Considering that the state legislature in Washington is split, with Democrats controlling the House and Republicans the Senate, I suspect that it will be difficult to get the funding stripped. However, if they do it will be a sign that we might have finally begun to turn a corner.

Near the Martian south pole

10:06 am

Near the Martian south pole

Cool image time! The image above, reduced and cropped to show here, shows an area at 87 degrees south latitude, not far from the south pole of Mars and in the region at the edge of its icecap of dry ice.

It is late summer in the Southern hemisphere, so the Sun is low in the sky and subtle topography is accentuated in orbital images.

We see many shallow pits in the bright residual cap of carbon dioxide ice (also called “Swiss cheese terrain”). There is also a deeper, circular formation that penetrates through the ice and dust. This might be an impact crater or it could be a collapse pit.

Because of the low Sun angle the bottom of the deep pit is poorly lit, making it hard to determine the pit’s nature. What can be seen at its bottom however are some patches of carbon dioxide ice, melting in the same manner as the dry ice in the surrounding terrain. Also, the dust pattern surrounding the pit indicates the prevailing winds at this location, consistently blowing to the northeast.

I am certain there will be additional photos taken of this pit, when the Sun is higher in the sky and its floor is thus better illuminated.

Road construction at SpaceX’s planned Texas spaceport

9:47 am

Capitalism in space: A $3 million road project at SpaceX’s planned spaceport at Boca Chica Beach near Brownsville, Texas, is moving forward.

The key tidbit from the article however is this:

Besides the property tax breaks and incentives that Cameron County and other entities around the RGV have already offered SpaceX to come to the Valley, Garcia said they’ll continue to do what it takes to stay on target for a 2018 launch. “Every month we’re going to be on the map,” he said.

It appears that the reason work on the spacepad itself has seemingly stalled is because SpaceX has been waiting for this road work by the state to be completed. Either way, they are aiming for a first launch next year. At that time SpaceX should have four launchpads, 2 in Florida, one in California, and one in Texas.

Astronomers find star with giant ringed planet

9:30 am

Astronomers now think that a sunlike star about 1,000 light years away dips in brightness every 2.5 years because an orbiting ringed planet or ringed dwarf star blocks the star’s light.

They discovered that every two and a half years, the light from this distant star – PDS 110 in the Orion constellation, which is same temperature and slightly larger than our sun – is reduced to thirty percent for about two to three weeks. Two notable eclipses observed were in November 2008 and January 2011. “What’s exciting is that during both eclipses we see the light from the star change rapidly, and that suggests that there are rings in the eclipsing object, but these rings are many times larger than the rings around Saturn,” says Leiden astronomer Matthew Kenworthy.

Assuming the dips in starlight are coming from an orbiting planet, the next eclipse is predicted to take place in September this year – and the star is bright enough that amateur astronomers all over the world will be able to witness it and gather new data. Only then will we be certain what is causing the mysterious eclipses.

If confirmed in September, PDS 110 will be the first giant ring system that has a known orbital period. [emphasis in original]

Just so no one is confused, this is not Tabby’s Star. There, the dips in light are seemingly random and follow no pattern, other than an overall dimming for the past century.

Pole of Saturn’s moon Enceladus shifted 55 degrees in the past

2:41 pm

Data from Cassini now suggests that the moon Enceladus shifted its pole as much as 55 degrees sometime in the past, possibly due to an impact.

Whether it was caused by an impact or some other process, Tajeddine and colleagues think the disruption and creation of the tiger-stripe terrain [at south pole] caused some of Enceladus’ mass to be redistributed, making the moon’s rotation unsteady and wobbly. The rotation would have eventually stabilized, likely taking more than a million years. By the time the rotation settled down, the north-south axis would have reoriented to pass through different points on the surface — a mechanism researchers call “true polar wander.”

Air Force successfully tests ICBM interceptor

2:31 pm

The Air Force today successfully shot down a dummy ICBM missile it had launched from the western Pacific.

As described prior to the test:

The U.S. will launch an ICBM-class target from the Reagan Test Site on Kwajalein Atoll in the Republic of the Marshall Islands and a ground-based interceptor from Vandenberg Air Force Base in California. If successful, the “kill vehicle,” or intercept, will collide with the ICBM test target mid-course over the Pacific Ocean… This will be the 18th test of the ground-based interceptor. The last one, in June 2014, was the first success since 2008. The system is nine for 17 since 1999 with other types of target missiles. An ICBM target has never been tested before.

I should note that this successful test is final proof that Reagan’s proposed Strategic Defense Initiative (SDI), or “Star Wars” as the leftist press contemptuously called it in their unwavering belief that it could not work, is feasible and can work.

Academic invents new non-oppressive physics to protect minorities

10:10 am

This paper is not a prank: A feminist gender studies academic from the University of Arizona has invented a theory of “intersectional quantum physics” to fight the oppression of Newtonian physics.

Whitney Stark argues in support of “combining intersectionality and quantum physics” to better understand “marginalized people” and to create “safer spaces” for them, in the latest issue of The Minnesota Review. Because traditional quantum physics theory has influenced humanity’s understanding of the world, it has also helped lend credence to the ongoing regime of racism, sexism and classism that hurts minorities, Stark writes in “Assembled Bodies: Reconfiguring Quantum Identities.”

What is also important is that this college researcher, who also has an appointment in the culture and gender studies department at Utrecht University in the Netherlands, got her paper published in a journal published by Duke University Press. Below is her full abstract. I dare you to tell me what it means.

In this semimanifesto, I approach how understandings of quantum physics and cyborgian bodies can (or always already do) ally with feminist anti-oppression practices long in use. The idea of the body (whether biological, social, or of work) is not stagnant, and new materialist feminisms help to recognize how multiple phenomena work together to behave in what can become legible at any given moment as a body. By utilizing the materiality of conceptions about connectivity often thought to be merely theoretical, by taking a critical look at the noncentralized and multiple movements of quantum physics, and by dehierarchizing the necessity of linear bodies through time, it becomes possible to reconfigure structures of value, longevity, and subjectivity in ways explicitly aligned with anti-oppression practices and identity politics. Combining intersectionality and quantum physics can provide for differing perspectives on organizing practices long used by marginalized people, for enabling apparatuses that allow for new possibilities of safer spaces, and for practices of accountability.

I also dare you to build a rocket using this new physics. I also wonder if anyone can tell the difference between this legitimate paper and this fake one.

Curiosity data increases time water existed Gale Crater

9:45 am

New research using data from Curiosity has found evidence suggesting that significant water was present in Gale Crater for a very long time.

Lighter-toned bedrock that surrounds fractures and comprises high concentrations of silica — called “halos”— has been found in Gale crater on Mars, indicating that the planet had liquid water much longer than previously believed. The new finding is reported in a new paper published today in Geophysical Research Letters, a journal of the American Geophysical Union.

“The concentration of silica is very high at the centerlines of these halos,” said Jens Frydenvang, a scientist at Los Alamos National Laboratory and the University of Copenhagen and lead author of the new study. “What we’re seeing is that silica appears to have migrated between very old sedimentary bedrock and into younger overlying rocks. The goal of NASA’s Curiosity rover mission has been to find out if Mars was ever habitable, and it has been very successful in showing that Gale crater once held a lake with water that we would even have been able to drink, but we still don’t know how long this habitable environment endured. What this finding tells us is that, even when the lake eventually evaporated, substantial amounts of groundwater were present for much longer than we previously thought—thus further expanding the window for when life might have existed on Mars.”

The actual paper provides no time frame. What it does state is that for the halos to have formed requires a lot of time, and that during that time a lot of groundwater was required.

Results after one year on ISS for Bigelow’s inflatable module

8:38 am

Capitalism in space: NASA has released some of its findings learned from Bigelow’s inflatable BEAM module, attached now to ISS for one year.

During the first year, NASA and its astronauts on board the station have sought primarily to test the module’s ability to withstand space debris—as a rapidly depressurized habitat would be a bad thing in space. And indeed, sensors inside the module have recorded “a few probable” impacts from micrometeoroid debris strikes, according to NASA’s Langley Research Center. Fortunately, the module’s multiple layers of kevlar-like weave have prevented any penetration by the debris.

They have also found that the cosmic ray dosage in the module seems comparable to the rest of the station. They are now using the module to test the radiation shielding capability of several different kinds of materials.

North Korea fires another ballistic missile

6:11 pm

North Korea today conducted its ninth ballistic missile test this year, all of which have been in violation of UN sanctions.

The missile, presumed to be a Scud type, was launched eastward from the vicinity of Wonsan, Gangwon Province, at around 5:39 a.m., according to the Joint Chiefs of Staff (JCS). “The flight distance is around 450 kilometers,” it said.

As a Scud, the missile would likely not have the capability of carrying a heavy payload, like a nuclear bomb. Nonetheless, with each test North Korea gains knowledge on how to do exactly that.

Dog sits on editorial board of seven medical journals

4:16 pm

An Australian professor wondered if he could get his dog Ollie picked to be on the editorial board of a number of medical journals, and was astonished to discover seven who agreed without reservations.

Ollie’s owner is Mike Daube, Professor of Health Policy at Curtin University in Perth. Ollie likes to watch Mike working on his computer, and Mike gets a lot of emails from predatory journals. Wondering just how low these journals would go, he put together a curriculum vitae for his dog – detailing research interests such as “the benefits of abdominal massage for medium-sized canines” – and sent it off to a number of these journals, asking for a spot on their editorial boards.

Remarkably, the vast majority accepted Ollie without demur, and her name now adorns several journal websites. Ollie is a trailblazer, Professor Daube says, being the first dog ever to get on the editorial board of a journal.

“What makes it even more bizarre is that one of these journals has actually asked Ollie to review an article. It’s entitled “Malignant peripheral nerve sheath tumours and their management.” Some poor soul has actually written an article on this theme in good faith, and the journal has sent it to a dog to review.”

The article provides a nice look at the problems facing the modern peer review journal field.
