The discovery in January 2018 of a number of Martian cliff faces, or scarps as the scientists dubbed them, with a visible and apparently very accessible underground layer of ice, had significant ramifications.

First, it proved that, in at least one area south of Hellas Basin and one spot in the northern hemisphere, an underground ice table existed on Mars at latitudes as far south as 55 degrees. Scientists had theorized that this ice table, comparable to the water table on Earth, existed, but here was visible proof.

Second, the discovery showed places where water could be accessed relatively easily by future colonists. There are plenty of indications from orbiter images and lander/rover data that water is present in many places on Mars, but here the water appeared almost pure and could be obtained without major digging or processing. Whether that ice table extends even farther south, making it even more accessible, remains as yet a scientific question.

In the next few months the scientists involved in this research located more ice scarps in areas beyond the range of those initial discoveries. Since then however even more scarps have been found, including the scarp in the image above and to the right, cropped, reduced, and annotated to post here.

This particular scarp is located inside a crater. The uncaptioned release from the high resolution camera on Mars Reconnaissance Orbiter (MRO), described it as a “Scarp in mantling material.” According to Colin Dundas of the U.S. Geological Survey’s Astrogeology Science Center in Arizona,

Supreme Court rules federal judges have no right to overturn gerrymandering

A victory for democracy: Supreme Court has ruled that federal judges have no authority to overturn congressional districts created by state legislatures.

The 5-4 opinion by Chief Justice John Roberts and joined by the court’s other conservatives said partisan election maps drawn by North Carolina Republicans and Maryland Democrats are constitutional despite their one-sided nature.

It was a dramatic withdrawal by the nation’s highest court from the political battles that have consumed states for decades, and it was loudly denounced by the court’s liberal justices.

“How do you decide where the line is between acceptable partisanship and too much partisanship?” Roberts said from the bench in announcing his ruling on the last day of the term. “At some point, it should occur to you that what you’ve been asked to do is not judging at all.” The chief justice said the challengers from North Carolina and Maryland asked for “an unprecedented expansion of judicial power” that would have broad consequences. “There will be no end to the litigation,” he said.

While this decision ends the use of the federal courts to override the decisions of elected state legislatures, the court has let stand state court actions that overrode gerrymandering. In the end, however, the essence here will shift political power back to the states and their legislatures.

Mold in space can tolerate very high doses of radiation

New research has discovered that the mold found on the International Space Station is able to tolerate very high doses of radiation.

Spores of the two most common types of mold on the ISS, Aspergillus and Pennicillium, survive X-ray exposure at 200 times the dose that would kill a human, according to Marta Cortesão, a microbiologist at the German Aerospace Center (DLR) in Cologne, who will present the new research Friday at the 2019 Astrobiology Science Conference (AbSciCon 2019).

Pennicillium and Aspergillus species are not usually harmful, but inhaling their spores in large amounts can sicken people with weakened immune systems. Mold spores can withstand extreme temperatures, ultraviolet light, chemicals and dry conditions. This resiliency makes them hard to kill.

“We now know that [fungal spores] resist radiation much more than we thought they would, to the point where we need to take them into consideration when we are cleaning spacecraft, inside and outside,” Cortesao said. “If we’re planning a long duration mission, we can plan on having these mold spores with us because probably they will survive the space travel.”

While these findings likely mean an increase in the cost for sterilizing future planetary probes, they also mean that fungi will be available for future space travelers for the production of antibiotics, food, and other useful items.

Vostochny contractor charged with embezzlement avoids jail

The new colonial movement: The contractor who embezzled almost $6.5 million from the Vostochny spaceport project in Russia has avoided jail time, getting merely a suspended sentence and and a $3,000 fine.

Viktor Grebnev, who headed the TMK contractor until it was declared bankrupt 2015, was accused of knowingly signing loss-making contracts and using company money to buy yachts and a mansion.

A district court in Far East Russia handed Grebnev a five-year suspended sentence and fined him 200,000 rubles ($3,000) for large-scale embezzlement, Interfax cited the court as saying.

It appears from this story that the corruption in Russia remains as strong as ever, which bodes poorly for its future in space. Space engineering is hard. If you allow any dishonesty to linger around it you are guaranteed to have something go wrong.

Hayabusa-2 to attempt 2nd sample grab

The new colonial movement: The Hayabusa-2 science team has decided to attempt a second touch-and-go sample grab from the man-made crater they created on the surface of the rubble-pile asteroid Ryugu.

JAXA engineers confirmed that the probe’s camera and other equipment that were slightly damaged by the first landing are usable, and that there are no big rocks at the candidate site. They gave the go-ahead for a landing on July 11.

Hayabusa2 is scheduled to begin its descent from an altitude of 20,000 meters at around 10 a.m. on July 10 Japan time, and touch down on the asteroid’s surface about 25 hours later.

This is the first time I have heard of any damage to the spacecraft from the first touch-and-go landing. Regardless, they have decided they can risk another sample grab and still have the ability to return the samples to Earth.

Europe finally admits it must build reusable rockets

The new colonial movement: Europe has finally admitted that its refusal with Ariane 6 to make it reusable was a mistake, and has begun a major engineering research project to design and fly two different types of reusable rockets.

This month, the European Commission revealed a new three-year project to develop technologies needed for two proposed reusable launch vehicles. The commission provided €3 million to the German space agency, DLR, and five companies to, in the words of a news release about the project, “tackle the shortcoming of know-how in reusable rockets in Europe.”

This new RETALT project’s goals are pretty explicit about copying the retro-propulsive engine firing technique used by SpaceX to land its Falcon 9 rocket first stages back on land and on autonomous drone ships. The Falcon 9 rocket’s ability to land and fly again is “currently dominating the global market,” the European project states. “We are convinced that it is absolutely necessary to investigate Retro Propulsion Assisted Landing Technologies to make re-usability state-of-the-art in Europe.”

What is interesting to me is what appears to be some internal politics within Europe surrounding this effort. France is generally the most dominate member of the European Space Agency. Yet, according to the press release for this announcement, France is not involved in these new reusable rocket projects. Instead, Germany dominates, with companies from Switzerland, Portugal, and Spain participating.

It could be that the failure of Ariane 6 to garner customers, due to its higher costs, has forced these ESA partners to push for their own reusable rocket projects.

Either way, the competition in rocket technology is heating up, more evidence that the 2020s will be the most exciting decade in space since the 1960s.

Chang’e-4 and Yutu-2 awake for 7th lunar day

The new colonial movement: Chinese engineers have awakened both the Chang’e-4 lander and the Yutu-2 rover to begin work on their seventh lunar day on the Moon’s far side.

The text of this Chinese news report is almost identical to the text in the news report a month ago, when both spacecraft were awakened for the sixth lunar day. And as before, it tells us little.

What today’s story reveals is that Yutu-2 traveled only about 75 feet during the sixth lunar day. With an overall odometer reading of 695 feet, it appears it is averaging about 100 feet per lunar day, with the per day number dropping with time. Either the science team is becoming cautious, or they have had unstated issues that have slowed them down.

Still, the rover’s nominal mission was only three lunar days, so it is survived more than twice as long as designed.

The Whirlpool Galaxy across many wavelengths

The Whirlpool Galaxy
Click for full image.

Cool image time! The sequence of images above, reduced to post here, were taken in multiple wavelengths by the 2.1 meter Kitt Peak National Observatory in Arizona and the Spitzer Space Telescope in orbit.

The Whirlpool galaxy, also known as Messier 51 and NGC 5194/5195, is actually a pair of galaxies that are tugging and distorting each other through their mutual gravitational attraction. Located approximately 23 million light-years away, it resides in the constellation Canes Venatici.

The leftmost panel shows the Whirlpool in visible light, much as our eye might see it through a powerful telescope. In fact, this image comes from the Kitt Peak National Observatory 2.1-meter (6.8-foot) telescope. The spiraling arms are laced with dark threads of dust that radiate little visible light and obscure stars positioned within or behind them.

The second panel from the left includes two visible-light wavelengths (in blue and green) from Kitt Peak but adds Spitzer’s infrared data in red. This emphasizes how the dark dust veins that block our view in visible light begin to light up at these longer, infrared wavelengths.

Spitzer’s full infrared view can be seen in the right two panels, which cover slightly different ranges of infrared light.

The infrared views of the Whirlpool galaxy also show how dramatically different its two component parts are: The smaller companion galaxy at the top of the image has been stripped nearly clean of dust features that stand out so brilliantly in the lower spiral galaxy. The faint bluish haze seen around the upper galaxy is likely the blended light from stars thrown out of the galaxies as these two objects pull at each other during their close approach.

The Spitzer images above are likely among the last we shall see from that telescope, which has been in orbit since 2003 with a planned mission of only 2.5 years. As its cryogenic coolant became depleted in 2009, it has been functioning in a somewhat limited phase since. NASA will officially end the mission on January 30, 2020, more than thirteen years beyond that initial lifespan.

Another odd crater on Mars

Odd shaped crater
Click for full image.

Cool image time! In a sense, to announce that scientists have found an oddly shaped crater on Mars is to state the obvious. In the years since the first Martian fly-by by Mariner 4 in 1965, scientists have been discovering numerous odd-shaped craters on Mars, every single of which has challenged our assumptions about the planet’s geology. I myself have posted a half dozen such posts since January (January 7, January 10, January 14, March 26, March 27, June 12).

Yet, it is always worth looking when another one crops up, because of the fact that they challenge our assumptions about Martian geology. They are also always cool to look at! On the right, cropped and reduced to post here, is an image taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on April 19, 2019 of what the scientists have dubbed an “Odd Shaped Crater in Arabia Terra.”

Overview map

Arabia Terra is one of the largest regions of the transition zone between the northern lowlands and the southern highlands. This crater is located, as shown by the red cross in the overview map to the right, near its northern edge, in an area where the descent into the northern lowlands is somewhat abrupt and broken up by large craters and chaos terrain.

The crater itself holds numerous geological mysteries. Its shape suggests two impacts of different sizes overlapping each other, but without any remnant of the inner rim of the second impact. Where did that remnant go? Or maybe this wasn’t caused by two impacts, but by one impact that reshaped the surface in this odd and inexplicable way.

Then there is the three teardrop-shaped patterns in the crater’s floor. They look like the brushstrokes of a giant-sized painter. Were they caused by the wind? And if so, why in this pattern?

Planetary geologists could probably come up with a dozen more questions. The number tells us how little we know about Mars.

Leftist backed by socialist Ocasio-Cortez wins in Queens

They’re coming for you next: A leftist candidate, Tiffany Cabán, backed by socialists Alexandra Ocasio-Cortez (D-New York) and Senator Bernie Sanders (D-Vermont), has won an election for Queens District Attorney in New York.

Cabán, Alexandria Ocasio-Cortez’s preferred pick for the office, garnered 39.5% of the vote compared to Democratic rival Melinda Katz’s 38.3% with 98% of precincts reporting.

…Cabán is a 31-year-old public defender who wants to decriminalize sex work, close Rikers Island and end cash bail. The young lawyer was joined on stage with city Comptroller Scott Stringer and state Sen. Jessica Ramos.

The election was close enough that they will do a recount, but I don’t think that will change the result, which clearly shows that New Yorkers have not been put off in the slightest by Ocasio-Cortez’s extreme leftist positions, as many conservative pundits have assumed. If anything, her upfront willingness to push her beliefs, no matter our senseless or impractical or ignorant, have garnered her side more support.

I am reminded again of this quote from Walter Miller’s great end-of-the-world science fiction novel, A Canticle for Leibowitz:

Listen, are we helpless? Are we doomed to do it again and again and again? Have we no choice but to play the Phoenix in an unending sequence of rise and fall? Assyria, Babylon, Egypt, Greece, Carthage, Rome, the Empires of Charlemagne and the Turk. Ground to dust and plowed with salt. Spain, France, Britain, America–burned into the oblivion of the centuries. And again and again and again.

Are we doomed to it, Lord, chained to the pendulum of our own mad clockwork, helpless to halt its swing?

It doesn’t seem to matter that communism, socialism, fascism, Nazism, all top-down authoritarian systems no matter what their name or design, have consistently failed, and failed horribly, causing the deaths of millions and millions. Worse, these failures have not been in the distant past, but within the lifetimes of almost everyone living today. Several (Venezuela and North Korea) are occurring right this minute.

Yet, Americans want to try it for themselves. Sadly, they (and we) will reap the whirlwind, for it will fail again, as horribly as it has every other time.

SpaceIL decides Beresheet-2 will not be lunar mission

The new colonial movement: The Israeli nonprofit company SpaceIL has decided that its second Beresheet spacecraft will not go to the Moon.

The association’s board of directors decided to involve the public in the process of choosing the challenge that Beresheet 2 will lead, as was done in the national mission to the moon. At the same time, the association will continue to focus on establishing the values ​​of the “Beresheet effect” among the younger generation in Israel.

What I think is really going on is that they have realized that they cannot raise the necessary cash to fly another lunar lander, and are therefore setting their sights lower in order to find a mission they can fund.

Elementary students to compete to name 2020 Mars rover

NASA has initiated a project to have the nation’s K-12 elementary school children compete to name the 2020 Mars rover.

NASA has selected two partner organizations to run a nationwide contest giving K-12 students in U.S. schools a chance to make history by naming the Mars 2020 rover. An application to become contest judge also is now available online.

Battelle Education, of Columbus, Ohio, and Future Engineers, of Burbank, California, will collaborate with NASA on the Mars 2020 “Name the Rover” contest, which will be open to students in the fall of 2019. The student contest is part of NASA’s efforts to engage the public in its missions to the Moon and Mars.

They are also looking for people to judge the contest.

Hacker steals JPL data

A hacker last year was successfully able to hack into the computer system at the Jet Propulsion Laboratory (JPL) in California and steal 500MB of data.

Who did the hacking is not revealed in the inspector general report [pdf], but the report lists six different hacks of JPL’s computers going back to 2009, two of which were linked to China. It is therefore reasonable to assume that China, which routinely steals new ground-breaking technology rather than develop it itself, was the likely culprit. In addition, the timing of these hacks, from 2009 to 2017, fits well with the steady growth of China’s lunar program. If you wanted to find out how to build an unmanned probe to go to the Moon, JPL would be the ideal facility to steal the technology from.

Soyuz has problem during return to Earth

In returning three astronauts safely to Earth yesterday from ISS the Soyuz spacecraft experienced a technical problem immediately after its engines had fired, causing it to go to a backup system.

Moments after the completion of the braking maneuver, the emergency signal was heard inside the Descent Module and the communications between the crew and mission control discussed a failure of the first manifold in the integrated propulsion system of the Soyuz spacecraft and the switch to the second manifold. Kononenko first reported K1B (Manifold DPO-B) emergency at 05:02:54 Moscow Time and subsequently confirmed a switch to the second manifold. NASA later confirmed the problem, but did not provide any details.

There is no explanation what the “first manifold” is, though I suspect it is a direct translation from Russian for their term for a primary system. That the system automatically switched to its back-up is a good thing. That there was a failure of the primary system is not.

Once again, this raises more questions about the quality control throughout Russia’s aerospace industry. While so far none of the recent Soyuz problems, which have also included a launch abort and a still-unexplained drilled hole, have caused a loss of life. I fear that soon or later they will.

SpaceX catches a fairing

Capitalism in space: During last night’s Falcon Heavy launch SpaceX was for the first time able to catch one of the rocket’s fairings using its ship, GO Ms. Tree (formerly called Mr. Steven).

As noted at the link, SpaceX now has in its hands a fairing untouched by salt water that it can analyze for future reuse, something no other rocket company has been able to do. Moreover, that the ship was able to make the net catch at night bodes well for future fairing recoveries.

Hat tip commenter geoffc.

Falcon Heavy launches successfully

Capitalism in space: The Falcon Heavy successfully launched tonight, and is presently deploying the 24 satellites on board.

They successfully landed the two first stage side boosters, but the core stage apparently just missed hitting the drone ship in the Atlantic. You could see it come down, but not on the pad. While SpaceX has now successfully recovered all six side boosters on all three Falcon Heavy launches, they have not yet succeeded in recovering the core stage.

The mission’s full success will not be known for several hours, as the satellite deployments unfold. So far the first two satellites have been deployed successfully.

The leaders in the 2019 launch race:

8 China
8 SpaceX
5 Russia
5 Europe (Arianespace)
3 India

The U.S. has now widened its lead over China in the national rankings, 13 to 8.

Falcon Heavy launch a go for 2:30 am (Eastern) tonight

Capitalism in space: SpaceX’s third Falcon Heavy launch is now a go for launch at 2:30 am (Eastern) tonight.

You can watch it live at SpaceX’s website here or at the embedded video below the fold.

This launch should be especially spectacular, as it will be at night, and the sky is clear. Moreover, they will once again be trying to land all three first stage boosters, with the side boosters flying for the second time only two months after their first flight on the last Falcon Heavy launch.

What the resurgence in animal life at Chernobyl can teach us

Link here. From the lead paragraph:

Three decades after the Chernobyl disaster—the world’s worst nuclear accident—signs of life are returning to the exclusion zone. Wild animals in Chernobyl are flourishing within the contaminated region; puppies roaming the area are capturing the hearts of thousands. Tourists who have watched the critically acclaimed HBO series Chernobyl are taking selfies with the ruins. Once thought to be forever uninhabitable, the Chernobyl Exclusion Zone has become a haven for flora and fauna that prove that life, as they say in Jurassic Park, finds a way.

Read it all. What the story really reveals is that the fear-mongering of the anti-nuclear movement (second cousin to the global warming movement) was at a minimum over-wrought and over-stated, and at its worst mostly a lie. The worst nuclear accident ever, that made a 1000-square-mile area forbidden territory due to radiation, has produced no truly terrible long term damage. Things are different, the radiation release had consequences, but the overall situation today appears generally positive, only three decades later.

Google censors Project Veritas expose on Google censorship

Leftist fascism: While I have noted this in my earlier post about Google’s effort to block both Trump’s election and many conservative sites, it is necessary to highlight: Google, the owner of youtube, has removed Project Veritas’s video expose from youtube.

The only reason they could have to do this is to block people from knowing about Google’s partisan and fascist behavior. You can still watch the video at the Project Veritas site.

As I said, people have to stop using Google. Both DuckDuckGo and StartPage are viable search engine alternatives, though the former is preferred because the latter depends on Google’s search engine.

If you have gmail, find an alternative. There are many.

And as I have said numerous times in the past, I would love it if those suggesting evening pauses for this website could find alternative sources other than youtube for those videos.

Exploring with Mars Reconnaissance Orbiter

Terrain sample
Click for full image.

In my never-ending rummaging through the images released each month from the high resolution camera on Mars Reconnaissance Orbiter (MRO), I have sometimes been puzzled by the titles they choose for some photographs. For example, many pictures each month are simply titled “Terrain Sample.” The image to the right, cropped and reduced to post here, is one example, and its content adds to the mystery.

The photograph itself shows a generally featureless surface. Other than the scattering of small craters, there are only very slight topographical changes, the most obvious of which is the meandering ridge to the east of the largest crater.

I wondered why this picture was taken, and why it was given such a nondescript name. To find out, I emailed Veronica Bray at the University of Arizona. She had requested this image as part of her job as a targeting specialist for MRO. Her answer:

Google’s hidden agenda: Stop Trump’s re-election

Project Veritas strikes again! A whistle-blower at Google has revealed that the internet company that dominates all search engines has a conscious policy to oppose the re-election of Donald Trump while simultaneously suppressing conservative websites.

Jen Gennai is the head of “Responsible Innovation” for Google, a sector that monitors and evaluates the responsible implementation of Artificial Intelligence (AI) technologies. In the video, Gennai says Google has been working diligently to “prevent” the results of the 2016 election from repeating in 2020: “We all got screwed over in 2016, again it wasn’t just us, it was, the people got screwed over, the news media got screwed over, like, everybody got screwed over so we’re rapidly been like, what happened there and how do we prevent it from happening again.

“We’re also training our algorithms, like, if 2016 happened again, would we have, would the outcome be different?”

There’s more at the link. For example, Google is also working to adjust its search algorithms to automatically suppress conservative websites from those searches. The goal, to use Google’s own words, is to make the company “the single point of truth” for news, with a perspective that is decidedly leftist and partisan.

The public has got to stop using Google. There are plenty of viable search engine options, such as DuckDuckGo and Startpage. I’ve been using both for almost a decade.

Regardless, it appears that this information will likely fuel the political movement to have the government break this company, as well as Facebook, apart. Though I’d rather the market did the job, these companies are very clearly violating the law that treats them not as news sources but as objective utilities, and thus protects them in certain ways. They need to find out that breaking the law will have negative consequences.

I have embedded the Project Veritas video below the fold. Watch it. It will horrify you. Not surprisingly, the fascists at Google/Youtube have censored the video. If you wish to see it, you need to go the Project Veritas link above.

Weird minerals discovered in simulated Titan environment

In recreating their best guess as to the conditions and environment of Saturn’s moon Titan, scientists have produced a number of weird never-before-seen minerals.

To create Titan-like conditions in the laboratory, the researchers started with a custom-built cryostat, an apparatus to keep things cold. They filled the cryostat with liquid nitrogen to bring the temperature down. They then warmed the chamber slightly, so the nitrogen turned to gas, which is mostly what Titan’s atmosphere contains. Next, they threw in what abounds on Titan, methane and ethane, as well as other carbon-containing molecules, and looked for what formed.

The first things to drop out of their Titan hydrocarbon soup were benzene crystals. Benzene is perhaps best known as a component of gasoline and is a snowflake-shaped molecule made out of a hexagonal ring of carbon atoms. But Titan benzene held a surprise: The molecules rearranged themselves and allowed ethane molecules inside, creating a co-crystal.

The researchers then discovered the acetylene and butane co-crystal, which is probably a lot more common on Titan than benzene crystals, based on what’s known about the moon’s composition, Cable said.

The scientists think that these crystals might be found on the edge of Titan’s methane lakes, encrusted there like a bathtub ring.

ULA postpones next Atlas 5 launch due to battery failure

An Atlas 5 launch of a military communications satellite that had been scheduled for this week has been postponed by ULA until July because of a battery failure on the rocket.

While ULA certainly does not have the same kind of quality control problems as the Russians, for them to discover a failure like this so close to launch is somewhat disturbing.

Then again, they discovered it before launch, which is the important thing.

Spike in methane detection in Gale Crater

The uncertainty of science: In the past week Curiosity has suddenly discovered a spike, the largest ever, in the amount of methane in the local atmosphere.

The amount detected was still quite tiny, 21 parts per billion by volume.

Curiosity doesn’t have instruments that can definitively say what the source of the methane is, or even if it’s coming from a local source within Gale Crater or elsewhere on the planet.

“With our current measurements, we have no way of telling if the methane source is biology or geology, or even ancient or modern,” said SAM Principal Investigator Paul Mahaffy of NASA’s Goddard Spaceflight Center in Greenbelt, Maryland.

While there is going to be a lot of speculation in the press and among scientists who should know better, this detection remains a major mystery. We as yet have no idea what caused it. Nor is it likely to have been caused by biology, though that does remain a possibility.

What is most puzzling is that the terrain that Curiosity is presently traveling across, the clay unit at the foot of Mount Sharp, shows no likely source.

This past weekend the scientists focused the rover’s instruments on this topic, in the hope this could help narrow the problem.

Opposition candidate wins redo election in Istanbul

The opposition candidate to the party of President Erdogan in Turkey today handily won the redo election in Istanbul.

Turkish opposition candidate Ekrem Imamoglu won the redo of the Istanbul mayor’s race by a landslide on Sunday, in a stinging indictment of President Recep Tayyip Erdogan’s economic policies and his refusal to accept an earlier defeat.

Imamoglu, backed by opposition parties including CHP, won 54% of the vote, and the ruling AK Party’s candidate, former Prime Minister Binali Yildirim captured 45%, according to state media. The political upstart broadened his margin of victory to nearly 800,000 votes from 14,000 in the March 31 balloting, in a clear sign voters are concerned about the crumbling of Turkey’s democratic foundations and an economy reeling from a spike in consumer prices and unemployment. [emphasis mine]

What this victory suggests is that there still remains in Turkey a semblance of democracy, despite the effort of Erdogan to eliminate it. What will happen next will tell us whether that country will reinforce that democracy, or end it entirely.
