The lava tubes and canyons of Cerberus Fossae

3:08 pm

Cerberus Fossae rock falls

Cool image time! In the November image release from the high resolution camera on Mars Reconnaissance Orbiter (MRO) I found the image on the right (cropped to post here), dubbed “Possible Rock Falls on Steep Slopes in Cerberus Fossae.” You can see the full image by clicking on the photo on the right.

The cropped section focuses on the steep cliffs of this deep canyon, formed when lava flowed down from the giant volcano Elysium Mons almost like water, following the faults created by the bulging volcanoes to carve a long series of parallel canyons more seven hundred miles in length. Not only can individual boulders be seen piled up on the base of the canyon, you can see on the lower right a large section of cliff that has broken off and partly fallen, propped now precariously on the cliff’s steep slope. I would not want to be hiking below it at the base of this canyon.

Elysium Mons and Cereberus Fossae

This photograph itself made me more interested in looking at other MRO images of Cerberus Fossae. The context map on the right shows that MRO has taken numerous images along the length of these faults, indicated by the red boxes. The location of the above image is shown by the white cross, at the western end where the canyons tend to be steep, deep, and pronounced. In taking a look at the many images of Cerberus Fossae, I found a variety of canyons, plus pit chains, lava tube skylights, and one especially intriguing image, posted below, that shows what appears to be an extended collapse along the length of what was once an underground lava tube.

Scientists to pollute atmosphere to stop global warming

9:27 am

The coming dark age: In order to stop global warming a team of scientists plan a first test of a method designed to block sunlight by injecting aerosols (the scientific term for pollution) into the upper atmosphere.

If all goes as planned, the Harvard team will be the first in the world to move solar geoengineering out of the lab and into the stratosphere, with a project called the Stratospheric Controlled Perturbation Experiment (SCoPEx). The first phase — a US$3-million test involving two flights of a steerable balloon 20 kilometres above the southwest United States — could launch as early as the first half of 2019. Once in place, the experiment would release small plumes of calcium carbonate, each of around 100 grams, roughly equivalent to the amount found in an average bottle of off-the-shelf antacid. The balloon would then turn around to observe how the particles disperse.

The test itself is extremely modest. Dai, whose doctoral work over the past four years has involved building a tabletop device to simulate and measure chemical reactions in the stratosphere in advance of the experiment, does not stress about concerns over such research. “I’m studying a chemical substance,” she says. “It’s not like it’s a nuclear bomb.”

Nevertheless, the experiment will be the first to fly under the banner of solar geoengineering. And so it is under intense scrutiny, including from some environmental groups, who say such efforts are a dangerous distraction from addressing the only permanent solution to climate change: reducing greenhouse-gas emissions. The scientific outcome of SCoPEx doesn’t really matter, says Jim Thomas, co-executive director of the ETC Group, an environmental advocacy organization in Val-David, near Montreal, Canada, that opposes geoengineering: “This is as much an experiment in changing social norms and crossing a line as it is a science experiment.” [emphasis mine]

The number of stupid and ill-documented conclusions mentioned in this article are so many it would be hard to list them all. For one, it assumes the climate is warming in a disastrous manner, an assumption that remains entirely unproven. For another, the last paragraph in the quote above illustrates how much politics dominates this scientific field. Science has nothing to do with this experiment.

Third, the risks involved in doing this kind of geoengineering are impossible to measure. They very easily could be very negative, for us and the environment. Fourth, the only objections to this experiment quoted in the article come from activist groups who believe in global warming, but would rather impose political restrictions on freedom and property rights than do geoengineering. Skepticism of the global warming theory is merely mentioned as an aside, coming from “the occasional conspiracy theorist.”

I could go on. The worst part of this article and the scientists proposing this work is their utter refusal to consider the gigantic amounts of research that has shown the many benefits of increased atmospheric carbon dioxide and warming for agriculture and plant growth. Global warming, should it happen, could have negative consequences, but the data so far is very far from conclusive.

Let me add one more side note: The same environmentalists who generally support geoengineering to halt global warming are also likely to agree with this infantile op-ed: Richard Branson and Elon Musk threaten the purity of space.

Despite all the money the US and Russia have spent attempting to show who has the biggest balls, space remains pure. But, while Nasa re-engages and fuels up for another go, so-called space pioneers and entrepreneurs are already selling seats.

I don’t know about you, but I don’t want space to be commercialised, owner [sic] by Richard Branson or Elon Musk. For me, this would ruin something very special.

I’d suggest you read it all, but I would fear your level of education and ability to think will be seriously damaged.

For these anti-human environmentalists, manipulating the Earth’s atmosphere, based on weak scientific theories, is perfectly okay. Having humans and private enterprise in space, however, is evil and must be prevented at all costs.

The empty-headed lack of thought and ignorance required to come to these conclusions, simultaneously, boggles my mind.

Investigators uncover extensive corruption in Roscosmos

9:05 am

An investigation of Roscosmos by Russian prosecutors has revealed extensive violations of law, all of which occurred in only the last year and a half.

The Russian Prosecutor General’s Office has detected systemic legal violations in the work of State Space Corporation, Roscosmos, between 2017 and the first half of 2018. In total, 1,700 violations had been revealed, Official Spokesman Alexander Kurennoy said, adding that 16 criminal cases had been launched.

“During the period between 2017 and the first six months of 2018, documents on the activities conducted by the previous management of Roscosmos had been reviewed. Systemic violations of the law had been detected, particularly regarding the state’s defense procurement, with research and development work having been conducted improperly. This also concerns the area linked to state-of-the-art engineering, and where work on registering patents on intellectual property is carried out, they had been often disrupted. This includes the deadline of defense missions, where evidence of poor-quality products being supplied had been revealed,” he told reporters.

Furthermore, prosecutors had revealed violations of procurement legislation, namely when it comes to pricing and import substitution. “Also, the situation in the rocket and space industry in general was deemed unsatisfactory since the corporation hadn’t enacted the required controls for the appropriate expenditure of budget funds by all of the enterprises’ branches,” Kurennoy stressed.

I expect this situation in Russia will get far worse, as the corruption is a feature, not a bug, in their government-run centralized aerospace industry.

A cubesat communications satellite for the Moon

8:58 am

Capitalism in space: The smallsat company Surrey Satellite Technology is designing a cubesat communications satellite set for launch in 2021 designed to test technology for providing communications in lunar space.

Surrey Satellite Technology Ltd (SSTL) has today announced that it is designing a low cost 35kg lunar communications satellite mission called DoT-4, targeted for a 2021 launch. DoT-4 will provide the communications relay back to Earth using the Goonhilly Deep Space Network, and will link up with a rover on the surface of the Moon. SSTL is currently in discussions with a number of parties for the lunar mission, and expects to disclose further information on mission partners and funding early in 2019.

Sarah Parker, Managing Director of SSTL, said “SSTL has led the way in pioneering the use of small satellites for over 30 years and we are now raising our sights to change the economics of space around the Moon, and beyond.”

DoT-4 will be the pre-cursor mission for a larger lunar communications satellite to follow in the 2023 timeframe which will carry a more robust payload and which will also have the potential for navigation services. SSTL’s ultimate aim is to launch a full constellation of lunar communications satellites offering full service capability to enable new and regular opportunities for science and exploration and economic development of the space environment beyond Earth’s orbit.

It appears that Surrey is trying to grab the market for providing communications services for both NASA’s Gateway project as well as the number of private small lunar rovers that are expected to launch in the coming years.

I should add that this project probably only exists because Surrey and its investors know that it will have affordable access to space, using the new smallsat rockets coming from Rocket Lab, Vector, and Virgin Orbital.

Hundreds gather at Flat-Earth conference

2:10 pm

The coming dark age: Hundreds of believers in the idea that the Earth is flat and not a sphere have gathered for a conference in Colorado this week.

“Was there ever any debate when you were in first grade and you were learning about cosmology? Was there anyone who disputed it ever in your whole life but now?” said Dorothy Novak, a flat-Earth believer.

As science — and common sense — have proven, the world is not flat. However, flat-Earth believers say otherwise. “Look with your own eyes. Go out to the beach on a cloudy day. Are the clouds curved?” asked Novak.

About 800 are expected to attend. More important, their conference is getting good press, as indicated by this article itself.

Anyone who has read my writings at any depth know that I honor the concept of skepticism as the first premise of all science, and even of our civilization. However, one mustn’t have so open a mind that all your brains fall out. For so many people to advocate something that has been demonstrated in innumerable ways — including sending humans around the Moon — to be obviously false, says much about the sad state of our civilization.

The MarCo cubesat success

1:29 pm

Mars as seen by MarCo-B

The two MarCO cubesats that successfully relayed data from InSight to Earth during its landing yesterday continue to function, with one even sending back images. The photo on the right, cropped and reduced slightly to post here, was taken by MarCo-B.

Neither of the MarCO CubeSats carry science instruments, but that didn’t stop the team from testing whether future CubeSats could perform useful science at Mars. As MarCO-A flew by, it conducted some impromptu radio science, transmitting signals through the edge of Mars’ atmosphere. Interference from the Martian atmosphere changes the signal when received on Earth, allowing scientists to determine how much atmosphere is present and, to some degree, what it’s made of.

“CubeSats have incredible potential to carry cameras and science instruments out to deep space,” said John Baker, JPL’s program manager for small spacecraft. “They’ll never replace the more capable spacecraft NASA is best known for developing. But they’re low-cost ride-alongs that can allow us to explore in new ways.”

As a bonus, some consumer-grade cameras aboard MarCO provided “drive-by” images as the CubeSats sailed past Mars. MarCO-B was programmed to turn so that it could image the planet in a sequence of shots as it approached Mars (before launch, MarCO-A’s cameras were found to be either non-functioning or too blurry to use).

This engineering test proves that we don’t need to build billion dollar spacecraft every time we wish to send an unmanned scouting ship to another world. Cubesats will soon do the job quite well, and for a tenth the cost.

And there will be a lot of money to be made. Governments and private entities of all types will be eager to buy the services of the garage-built planetary cubesats that private companies are going to soon be building, in large numbers.

Supreme Court limits government’s attempt steal land for endangered species

11:12 am

The Supreme Court today ruled against the federal government’s attempt to designate private land as a habitat for an endangered species, even though that endangered species doesn’t even inhabit that land.

In a unanimous ruling the justices rejected the federal government’s attempt to designate roughly 1,500 acres in Louisiana as critical space for the dusky gopher frog. “Only the ‘habitat’ of the endangered species is eligible for designation as critical habitat,” Chief Justice John G. Roberts Jr. wrote in the opinion.

The frog hasn’t lived on the land in five decades, having shifted to neighboring counties. But the government, fearing future events might push the frog back, sought to designate the land, which would have imposed severe restrictions on what the owners could do with it.

Consider the chutzpah of the federal government in attempting to do this. If the court had ruled in their favor, it would have allowed them to designate any piece of property anywhere in the country as a habitat for any species, and thus negate all property rights, forever.

Moon rocks for sale!

11:07 am

Several rocks brought back from the Moon by a Soviet unmanned spacecraft will be auctioned off on November 29, and you can buy them legally!

The lunar samples were originally presented by the Soviet government to Nina Ivanovna Koroleva, the widow of Sergei Korolev, the “Chief Designer” of the Russian space program. Under Korolev’s direction, the Soviet Union successfully put the world’s first satellite into Earth orbit and launched the first human into space. His unexpected death in 1966 came before he could see the outcome of the space race to the moon.

Four years after Korolev died, the Soviets launched Luna 16, the first of three robotic lunar sample return missions. Touching down after the U.S. Apollo 11 and Apollo 12 astronauts had come and gone from the moon, Luna 16 deployed an extendable arm to drill and extract a core sample 14 inches (35 centimeters) deep. The 3.5 ounces (101 grams) of soil and rocks that it collected were then deposited into a capsule for their return to Earth.

The display gifted to Koroleva contains three grains of the Luna 16 material, weighing about 0.0007 ounces (0.2 grams). The central fragment is basalt, typical of the moon’s mare (or “seas”) terrain while the adjoining two larger fragments are regolith with glass coatings caused by an micrometeoroid impact, according to Sotheby’s.

…In 1993, the lunar samples were estimated to sell for $30,000 to $50,000 before commanding eight times the higher valuation. The display, which has been held in the same private American collection for the past quarter century, is now expected to sell for $700,000 to $1 million.

I will not be surprised if this item sells for considerably more than $1 million.

The war against our failed cultural elitists

9:30 am

Link here. The author outlines quite nicely the source of today’s vicious war against Trump.

Today a well-entrenched class of professional thinkers largely understands expertise as the product of formal education and relationships to elite universities: You become an expert, or start to, by acquiring academic credentials. Extra points for grad school, and more points still for being a professor like Paul Krugman or Jonathan Gruber. Like the administrative class in Vichy France, or the scholar-officials of imperial China, you’re smart if you go to school a lot and excel on your exams, so you get to be in charge of some piece of the political or cultural mechanism.

But is it working? Are our credentialing instruments producing people who are capable of practical action? To borrow a question from firefighters, can our credential-holders put the wet stuff on the red stuff?

Nearly a decade ago, Angelo Codevilla noticed the calcification of the American ruling class, a thing we sometimes pretend not to have. Our elites, he wrote, are “formed by an educational system that exposed them to the same ideas and gave them remarkably uniform guidance, as well as tastes and habits.” Thoroughly enculturated, the American elite gathers itself around a “social canon” that one does not question. Speaking of societal controversy with the wrong words puts a person outside the circle, out there in flyover country with the deplorables.

Considering the disaster that the federal government has become in the past half century, run as it is by this “class of professional thinkers,” I will say unequivocally that this system is not working. In the past half century this elitist culture has brought us bankruptcy, unmanageable debt, corruption, and a government unable to accomplish anything except to over-regulate and oppress the private citizen.

Read it all. The author describes well the situation we are in, as well as the reasons why there is so much hysterical opposition to Trump. This president poses a direct threat to the power of that elitist culture, and they are doing everything they can to stop him.

Their problem: They don’t know how to really accomplish anything, and for this reason Trump keeps running rings around them. To quote the article again:

For 40 years, with gathering uniformity of purpose, our credentialing institutions have taught postures rather than skills, attitudes rather than knowledge. This isn’t invariably true, and many fine scholars have taught many excellent practitioners, especially outside of the humanities and social sciences. But the overarching trend is toward training in intellectual and psychological uniformity, toward the world of excellent sheep.

The hollowing out of our credentialing institutions has been abundantly clear for years, in well-known examples like the discussion of rape law at Harvard and the “it is not about creating an intellectual space!” tantrum over Halloween costumes at Yale. What credentialing institutions teach is mental rigidity, intellectual cowardice, and the fear of disagreement. They narrow the mind and constrain the ability to act. Our elites largely can’t put the wet stuff on the red stuff, because it’s triggering and unsafe to mention that the red stuff is there, and why are you being so hurtful when I don’t want to talk about this?

But they have great power, and are doing whatever they can to hold onto that power. And worse, it appears that too many Americans support them.

Local opposition might delay UK spaceport

8:58 am

The United Kingdom’s first spaceport, proposed for the northern tip of Scotland, faces strong opposition from the local community as well as within the organization that owns the land.

The land is controlled by the Melness Crofting Estate (MCE), a company that represents about 56 local crofters. Three of its seven directors have resigned over how the plans have been handled.

George Wyper, one of those who stepped down, claimed that much of the community had been kept in the dark. In a ballot, 27 crofters voted to press ahead with talks to lease land to the spaceport while 18 voted against. Ten failed to vote and one ballot was rejected. Mr Wyper believes that important details were not shared. ‘Some people did not know what they were voting for,’ he said. ‘It’s getting quite vicious here — with Facebook and things. It’s causing a split in the community.’

He told the Highland Press & Journal: ‘There is quite a split in the community and a lot of bad feeling about this. It could go to the Scottish Land Court, which could take years to resolve.’

While in many ways some aspects of the opposition here reminds me of the opposition in Hawaii to the Thirty Meter Telescope, the difference is that that here it a large percentage of the landowners protesting. They have real standing, and thus are in a much stronger position to shut the spaceport down.

From what I can gather, the source of the problem here falls to the UK government, which apparently has done a very bad job in negotiating this deal.

InSight’s solar panels have opened

9:24 pm

InSight engineers have now reported that solar panels have opened and are functioning properly.

NASA’s InSight has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface. NASA’s Mars Odyssey orbiter relayed the signals, which were received on Earth at about 5:30 p.m. PST (8:30 p.m. EST). Solar array deployment ensures the spacecraft can recharge its batteries each day. Odyssey also relayed a pair of images showing InSight’s landing site.

“The InSight team can rest a little easier tonight now that we know the spacecraft solar arrays are deployed and recharging the batteries,” said Tom Hoffman, InSight’s project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California.

This was the last major event in the landing sequence, and with it they can now shift to the slow deployment of instruments over the next few weeks. Results from this spacecraft will not be sudden or spectacular. It is going to take time to get the spectrometer placed and than time to gather quake data.

InSight has successfully landed

12:58 pm

NASA engineers have received confirmation that InSight has successfully touched down on the Martian surface.

Don’t count your chickens yet. They need to wait about five hours for the dust, kicked up by landing, to settle before they try opening the solar panels. That must succeed, or the mission will fail, having no source of power.

The landing information was relayed through the two MARCO cubesats flying past Mars, a landmark engineering achievement that in a sense is more significant than the landing itself. These cubesats have demonstrated that smallsats can do complex interplanetary tasks. Expect a revolution in the planetary space exploration world.

Google wants to monitor our movements, moods, and children

3:46 pm

Another reason to dump Google: Google has been issued patents outlining its plans to establish monitors throughout each customer’s home, monitoring movements, moods, activities, and even their children, with the ability to even control behavior.

But there’s even more. According to The Atlantic:

A second patent proposes a smart-home system that would help run the household, using sensors and cameras to restrict kids’ behavior. Parents could program a device to note if it overhears ‘foul language’ from children, scan internet usage for mature or objectionable content, or use ‘occupancy sensors’ to determine if certain areas of the house are accessed while they’re gone— for example, the liquor cabinet. The system could be set to ‘change a smart lighting system color to red and flash the lights’ as a warning to children or even power off lights and devices if they’re grounded.

The language of these patents makes it clear that Google is acutely aware of the powers of inference it has already, even without cameras, by augmenting speakers to recognize the noises you make as you move around the house. The auditory inferences are startling: Google’s smart-home system can infer ‘if a household member is working’ from ‘an audio signature of keyboard clicking, a desk chair moving, and/or papers shuffling.’ Google can make inferences on your mood based on whether it hears raised voices or crying, on when you’re in the kitchen based on the sound of the fridge door opening, on your dental hygiene based on ‘the sounds and/or images of teeth brushing.’

The key aspect of this is that, at least right now, Google cannot force its way into your home unless you agree to let it. That any free American is not sickened by this invasion of privacy and is even considering allowing it into their home illustrates how different a country we are from only a half century ago. In my youth, for any company to publicly consider these actions would have guaranteed its bankruptcy, within weeks. No one would want anything to do with it.

No longer. Too many Americans are now sheep, wedded to their technology to a point of foolishness.

Update: I realized it will help to add that I have managed to eliminate almost all use of Google in my computer work now for more than a decade. For browser searches I use either Startpage or DuckDuckGo. For awhile I was using gmail as a backup email source, in case my main isp went down, but I dumped it about four years ago. With both Google and gmail I then wiped my history so as to reduce the odds of Google retaining it (something I can’t guarantee as Google has already been caught retaining data it does not own).

The only areas I am still using any Google resources is with youtube and Google Maps, and with both I am constantly looking for alternatives. We should all be doing the same. If anything the competition will force Google to reconsider some of its more odious policies.

Quasars that shut off

8:37 am

The uncertainty of science: Astronomers have discovered a class of quasars that suddenly turn off, something that no theory had predicted possible.

LaMassa, an astronomer now at the Space Telescope Science Institute, was mystified. Until that moment in 2014, she, like so many others, had expected quasars to be relatively stagnant. “Then you see these drastic changes within a human lifetime, and it’s pretty cool,” she said.

Confusion turned into excitement, and a hunt began to find more of these oddities. Although less luminous examples had already been seen, astronomers wanted to know if changes as dramatic as the one LaMassa discovered were common. It was no straightforward task, given that surveys tend not to go back and look at objects they have previously observed. But astronomers searched through archived data and discovered 50 to 100 more of what became known as “changing-look quasars.” Some of these have dimmed substantially more than LaMassa’s first example. Others have transitioned in the space of a month or two. And others, after disappearing, have reappeared again.

“It’s clear that the reason we weren’t finding these objects before is that we weren’t looking for them,” said Eric Morganson, an astronomer at the University of Illinois.

The article does a fine job of explaining the whole problem, including outlining the theories now being posited to explain these events. Bottom line: the universe is always more complicated that expected by initial observations.

Bennu from 85 miles

8:53 am

Bennu at 85 miles

The OSIRIS-REx science team today released a new image of Bennu, taken by the spacecraft from only 85 miles on November 16, two weeks ago Its contrast has been increased to bring out the details.

The asteroid continues to remind me of Ryugu, a rubble pile of boulders with few smooth spots. I suspect the OSIRIS-REx engineers are going to struggle as much as the Hayabusa-2 engineers are in an effort to find a safe spot to grab a sample. The advantage however for OSIRIS-REx is that the main body of the spacecraft doesn’t have to get as close to the surface as with Hayabusa-2. They will come down only close enough for the robot arm to touch down.

Rendezvous is set for December 3.

ESA plans Vega rocket upgrades

9:33 am

In order to grab more market share, the European Space Agency today outlined a wide range of upgrades and options it is creating for its Vega rocket.

The article describes versions aimed at the smallsat market, the geosynchronous satellite market, and a recoverable mini-shuttle similar to the X-37B, dubbed Space Rider. All these options are expected to come on line by 2021.

Isn’t competition wonderful? Threatened by loss of market share by SpaceX, Europe has been forced to up its game, something it had been loath to do for decades.

Potentially dangerous bacteria found on ISS

9:24 am

Researchers have found five strains of bacteria on ISS that, while not dangerous now, has the potential to mutate into forms that could be a threat.

When Bezdan and colleagues ran the numbers on the space station microbes, however, they found that they were similar to only three – and rare ones, at that. They report similarities with strains found to date only once – one recovered from neonatal blood in a Tanzanian patient, another from a neonatal urine sample in the US, and the third from a 72-year-old woman with multiple health problems. In total, the researchers report, the eight strains thus “formed a unique ecotype”.

The ISS strains all contained genes associated with drug-resistance. They did not, however, contain combinations associated with high infection rates. Nevertheless, the results are enough for the researchers to sound a warning.

There are a lot of uncertainties here, including a lack of understanding of the effect of weighlessness on these bacteria. Nonetheless, this research highlights an important problem for future interplanetary spacecraft that has generally been ignored: Their small and limited ecology is very vulnerable to this kind of threat.

India wants international instruments for its Venus mission

9:16 am

The new colonial movement: India has requested science instruments proposals from the international community for its planned Venus orbiter, set to launch in 2023.

ISRO has already selected 12 instruments, proposed by Indian scientists, including cameras and chemical analyzers to study the atmosphere. Now, it’s hoping other scientists will join. “Planetary exploration should be all about global partnerships,” says Kailasavadivoo Sivan, a rocket scientist and ISRO’s chair. (The deadline for submitting proposals is 20 December.)

For me, the big news with this article is that it is the very first I have seen that actually spells out Sivan’s first name. Since he became head of ISRO in January 2018, he has only been listed as “K. Sivan” in every single article, even those describing his background when he was appointed. Now that I have learned what a tongue-twister that first name is, I can understand why they abbreviate it.

On a more serious note, this article indicates the growing maturity of India’s space effort. They not only are planning a mission to Venus, they will fly missions to the Moon in January and Mars in 2022, and intend to launch their first manned mission in that same time period.

Groundwork and licensing begins for first test flights of SpaceX’s Starship

9:31 am

Capitalism in space: Even as SpaceX has apparently begun the licensing process with the FAA for its planned hopper tests for its Super Heavy and Starship heavy lift reusable rockets, it is also accelerating work for those flights at its Boca Chica spaceport in Texas.

The applications apparently describe a two-stage testing program divided into low then high altitude flights, “running approximately three times per week.” Meanwhile, at Boca Chica SpaceX has begin building a giant tent as well as other work.

While I doubt they will be able to begin test flights in 2019 as they have announced, it is clear those test flights will happen in the near future.

Another star found that dims strangely like Tabby’s Star

9:20 am

Astronomers have found a second star that dims in an inexplicable manner, like Tabby’s Star.

Known as VVV-WIT-07, the star appears to be much older and redder than our sun, although the amount of interstellar dust between our solar system and the star’s home closer to the galactic center makes exact classification and distance measurements very difficult. What is certain is that in the summer of 2012, the object’s brightness faded slightly for 11 days, then plummeted over the following 48 days, suggesting that something blocked more than three quarters of the star’s light streaming toward Earth. But what could that “something” be?

According to Eric Mamajek, an astrophysicist at the University of Rochester unaffiliated with the VVV survey, such a profound degree of dimming suggests that a staggeringly large object or group of objects is blocking the light. “It’s got to be over a million kilometers wide, and very dense to be able to block that much starlight,” he says. Mamajek should know: He led the team that discovered J1407, another strange star periodically eclipsed by a planet-sized object thought to boast a massive ring system some 200 times broader than that of Saturn. In this latest case, he says, the strange signals from VVV-WIT-07 could arise from clumps or clouds of material passing between Earth and the star, though he cautioned that the data were preliminary and more observations are required.

Tabetha Boyajian agrees. Boyajian, an astronomer at Louisiana State University, was the lead author for the 2015 paper announcing the strange dimming of KIC 8462852, also known as Tabby’s Star, an unusual object first spotted by NASA’s Kepler Space Telescope. VVV-WIT-07 would have to harbor “a very peculiar kind of dust cloud to make these kinds of dips,” Boyajian says. Boyajian’s study helped spark a surge of public interest in Tabby’s Star because the star’s unusual dimming could be seen as evidence of an alien civilization building an artificial structure that soaked up the star’s light. More conventional explanations include a swarm of comets or fragments from a shattered planet, both of which would create significant clouds of dust and debris that could also occlude the star’s light. But, so far, no simple single explanation fits the complexities of the dimming seen around the star; researchers remain stymied in their attempts to understand the true nature of the strange dimming of Tabby’s Star.

As is usually the case in these cases, the explanation will not be aliens. That it could be, however, is what makes it so intriguing.

Date set for first unmanned launch of manned Dragon

10:19 pm

Capitalism in space: NASA announced today that SpaceX has set January 7, 2019 as the launch date for its first unmanned test flight of its manned Dragon capsule.

SpaceX is targeting Jan. 7 for launch of its first Crew Dragon commercial ferry ship on an unpiloted test flight to the International Space Station, NASA announced Wednesday, a major milestone in the agency’s drive to end its sole reliance on Russian Soyuz crew ships for carrying astronauts to orbit.

If the shakedown flight goes smoothly — and if a NASA safety probe unveiled Tuesday doesn’t turn up any show stoppers — SpaceX could be ready to launch the first piloted Crew Dragon atop a Falcon 9 rocket in the June timeframe, carrying veteran NASA astronauts Robert Behnken and Douglas Hurley to the space station. [emphasis mine]

As I said during a taping today for my appearance on WCCO radio tomorrow at 11:10 am (Central), the only thing standing in the way of SpaceX getting its manned capsule off the ground is NASA. June is a long time from now, and the agency, egged on by corrupt politicians, could easily find ways to delay that first manned launch in that time. Nor would I put it past the corrupt Washington in-crowd, led by Senator Richard Shelby (R- Alabama), having no interest in the national interest, to do what they can to sabotage that flight. What they care about is diverting tax dollars to either their own pockets or to the pockets of their allies (which also helps bring them pay-offs campaign contributions as well).

Still, it is encouraging that SpaceX is pushing forward, and that there appear to be strong elements in NASA supporting them. Keep your fingers crossed.

Cool image time! The science team from Lunar Reconnaissance Orbiter (LRO) today released a new image, taken on November 3, 2018, of a relatively young small crater not easily seen from Earth.

The unnamed crater, just 1.8 kilometers across, is too small to see from Earth with unaided eyes. It is in the Moon’s wild west, just past Oceanus Procellarum and close to the line dividing the nearside from the farside, so it would be hard to glimpse in any case. If you stood on the crater rim, you would see the Earth forever slowly bobbing up, down, and sideways close to the eastern horizon.

The image above is a cropped and reduced-in-resolution section of the released image. If you click on it you can see this section at full resolution.

What I find fascinating about this crater are the black streaks that appear to only run down the outside slopes of the eastern rim, but nowhere else. At first glance it looks like prevailing winds, blowing from the west, caused this, but of course that’s wrong because the Moon has no atmosphere. The website explains:

NASA opens safety review of Boeing and SpaceX

9:15 am

Turf war! Prompted by Elon Musk’s single hit of marijuana during a podcast interview, NASA has begun a detailed safety review of both SpaceX and Boeing.

[William Gerstenmaier, NASA’s associate administrator for human exploration,] said the review would focus not on the technical details of developing rockets and spacecraft but rather the companies’ safety culture — encompassing the number of hours employees work, drug policies, leadership and management styles, whether employees’ safety concerns are taken seriously, and more.

“Is the culture reflective of an environment that builds quality spacecraft,” Gerstenmaier said. The review would be led by NASA’s Office of Safety and Mission Assurance, which has conducted similar probes inside NASA. Gerstenmaier said the process would be “pretty invasive,” involving hundreds of interviews with employees at every level of the companies and at multiple work locations.

This is a power-play, pure and simple. NASA might claim it cares about safety, but its track record suggests instead that its real motive is to prove to SpaceX that it is in charge, not SpaceX. It rankles NASA’s bureaucracy that they cannot call the shots at SpaceX, and have found themselves embarrassed by its success, compared to the agency’s continuing failures with SLS. Moreover, considering the space shuttle’s unsafe history, NASA’s safety track record and the workplace culture that produced that history is nothing to brag about.

These “invasive” interviews are guaranteed to find workplace issues that NASA will then use as a hammer to take further control SpaceX’s operations, making it less innovative, more expensive, and more bureaucratic. And I see no one in the Trump administration, including Trump, very interested in reining NASA in on these matters.

Corruption at Vostochny included more than 140 criminal cases

9:00 am

A report from Russia today outlined the total amount of corruption so far uncovered by investigators at Russia’s new spaceport in Vostochny.

“Since 2014, more than 140 criminal cases have been opened, and the damage was assessed at 10 bln rubles,” Kurennoy said in an interview with the Efir Internet channel of the Russian Prosecutor-General’s Office. According to the spokesman, 50 individuals have been sentenced, and this year sentences for 27 people were announced.

The prosecutors have revealed 17,000 law violations during the construction since 2014. More than 1,000 people have been held accountable, including officials. Among the violations were delayed construction, multibillion embezzlement of state funds and the administration’s negligence.

Despite four years of investigation they still found 78 new law violations involving 140 companies in 2018.

It appears Russia does not know how to do capitalism properly. It doesn’t simply require a company to be privately owned. It also requires that new companies be allowed to compete, and that old companies can go out of business. Russia it appears did not understand these latter points. After the fall of the Soviet Union many individuals formed private companies from former government agencies and organizations, but then they divided up the market into territories and teamed up with the government to block any new entries.

The result of this corrupt system was rampant corruption, where the companies in power could do anything, with no incentive to produce good product.

Unfortunately, Russia’s answer to this has been for the government to take over the companies again.This will not solve their problem, merely shift the corruption from the companies to the government. Meanwhile, the quality of their aerospace products will continue to decline, resulting in the continued loss of international market share.

NASA to hire private lunar probes for future missions

10:22 am

Capitalism in space: Rather than build its own future lunar landers and rovers, NASA is now planning to hire these services from private companies, with missions flying as soon as 2021.

Under a program called Commercial Lunar Payload Services (CLPS), NASA would buy space aboard a couple of launches a year, starting in 2021. The effort is similar to an agency program that paid private space companies such as Elon Musk’s SpaceX to deliver cargo to the International Space Station (ISS). “This a new way of doing business,” says Sarah Noble, a planetary scientist at NASA headquarters in Washington, D.C., who is leading the science side of NASA’s lunar plans.

Scientists are lining up for a ride. “It really feels like the future of lunar exploration,” says Erica Jawin, a planetary scientist at the Smithsonian Institution’s National Museum of Natural History in Washington, D.C. She and other attendees at the annual meeting of the Lunar Exploration Analysis Group in Columbia, Maryland, last week were eager to show NASA why their small experiments would be worthy hitchhikers on the landers.

Several companies, including Astrobotic, Moon Express, and iSpace, are vying to establish a commercial moon market. Buying rides to the moon from launch providers like Rocket Lab, each firm hopes to become the go-to carrier for other companies seeking to prospect the moon for rocket fuel ingredients, or to gather rocks to sell for study. But a contract with NASA is the real prize. Moon Express, for example, has designed the MX-1, a lander roughly the size and shape of Star Wars’s R2-D2. But, “We won’t pull the trigger until we know we have a CLPS award,” says Moon Express CEO Robert Richards in Cape Canaveral, Florida.

The companies selected for CLPS must deliver at least 10 kilograms of payload by the end of 2021, NASA says. It is scrambling to find instruments that are ready to fly. “What do you have sitting on shelf now that you can throw onto the mission immediately?” Noble says. “We’re looking for flight spares, engineering models, student-built projects. It’s a little bit of a weird call for us.” The agency is planning to pay up to $36 million to adapt eight to 12 existing scientific instruments to the initial small landers; by the middle of next decade it aims to build a pipeline of instruments for bigger landers that might also carry rovers.

These are going to small missions with limited lifespans and limited abilities. They will however be cheap, fast, and many. In the end I am certain NASA (and the taxpayer) will get far more bang for the buck.

SpaceX now seeking a $250 million loan, not $500 million

10:16 am

Capitalism in space: SpaceX has reduced the private loan it is seeking from $500 to $750 million down to $250 million.

Goldman Sachs Group Inc. was initially canvassing investors for a $500 million deal for SpaceX. During marketing of the loan, Musk changed advisers and chose Bank of America to officially launch the deal to investors at $750 million.

The switch surprised bankers and investors, as Goldman is widely viewed as the Wall Street firm closest to Musk. It helped take Tesla Inc. public in 2010, led its $1.8 billion bond sale last year and advised Musk on his short-lived attempt to take the electric carmaker private for $420 a share Goldman balked when SpaceX, a first-time issuer, wanted wide latitude to raise additional debt in the future, people with knowledge of the matter said earlier this month.

The loan isn’t the only way Musk has been trying to raise cash with SpaceX, which was founded in 2002 and last valued at about $28 billion. He also recently inquired with at least one bank about a personal loan tied to his stake in the rocket company, a person with knowledge of the matter said earlier this month.

It seems to me that Musk is acting here in a manner that will allow him to maintain as much independence as possible, a very wise approach.
