Indonesia to building rocket and spaceport

November 18, 2019 8:11 am Robert Zimmerman

The new colonial movement: Officials from Indonesia’s space agency, LAPAN, today revealed that they picked a location for a new larger spaceport, and will use it to test their own home-grown rocket.

Indonesia plans to construct its first spaceport in Biak, Papua, to serve the country’s rocket test launches, the country’s National Institute of Aeronautics and Space (LAPAN) has confirmed.

LAPAN flight and aerospace study centre head Robertus Heru Trijahyanto said Indonesia will build the spaceport following LAPAN’s existing rocket launch site in South Garut on West Java. However, it will be bigger so that it can be used for larger test launches.

The article mentions that they will get help from international partners, but provides little detail.

Second Kuaizhou-1A launch in less than a week

November 18, 2019 8:03 am Robert Zimmerman

The new colonial movement: China today successfully completed its second Kuaizhou-1A launch in four days, placing two communications satellites into orbit.

In just a little more than a four day period, from the very same pad, with the very same launch team and launch truck, China has launched yet another Kuaizhou-1A rocket carrying satellites into orbit.

…The Kuaizhou-1A is a 4 stage, mostly solid fuel powered launch vehicle developed by China Aerospace Science and Technology Corporation (CASIC) and commercialized by the China Space Sanjiang Group Corporation (also known as Expace Corporation).

Promoted by CASIC as being high reliability, high precision and low cost, the launch vehicle can send a 200 kg payload into a 700 km altitude sun-synchronous orbit. The vehicle is possibly based on the road-mobile DF-21 missile, with two additional solid fuel upper stages and a re-startable liquid fuel upper stage. It was designed with the goal to provide an easy to operate quick-reaction launch vehicle, that can remain in storage for long periods and to provide launch missions on short notice.

The leaders in the 2019 launch race:

25 China
17 Russia
11 SpaceX
6 Europe (Arianespace)

In the national rankings, China widened its lead over the U.S. to 25 to 23.

A quick holiday fund-raising campaign for Behind the Black

November 18, 2019 6:00 am Robert Zimmerman

In past years I have managed to avoid asking for donations for Behind the Black during the holiday season. My finances however now compel me to do a short one-week fund-raiser, from November 11 to November 17.

I do not use Twitter for ethical reasons, which I have been told cuts down on traffic to the website. So be it. Furthermore, Facebook has clearly acted in the past two years to limit traffic to Behind the Black, almost certainly for political reasons. So be this as well.

Finally, I do not post outside ads, as I have found them annoying to my readers and not that profitable to me.

Therefore, I need to ask for the direct support from my readers. If you like what I do here, please consider contributing, either by making a one-time donation or a monthly subscription, as indicated at the tip jar to the right or below. Or if you prefer sending an old fashioned check, you can do so by mailing it, payable to Robert Zimmerman, to:

Behind The Black,
c/o Robert Zimmerman
P.O.Box 1262
Cortaro, AZ 85652

Or you could consider purchasing one of my books, as indicated in the boxes scattered throughout the website. My histories of space exploration are award-winning and are aimed for the general public. All are page-turners, and all not only tell the story of the beginning of the human exploration of space, they also help explain why we are where we are today. And I also have a science fiction book available, Pioneer, which tells its own exciting story while trying to predict what life in space will be like two hundred years in the future.

Note that for this week only I am also having a sale on the purchase of the last 20 hardbacks of Leaving Earth. (Click on the link for more information about the book, which was endorsed by Arthur C. Clarke himself!) This award-winning out-of-print book is now only available as an ebook, but I still have a handful of hardbacks available, normally for sale for $70 plus $5 shipping. For this week only you can buy them, personally autographed by me, for $50 plus $5 shipping! Just send me a check, payable to Robert Zimmerman, to the address above, with a note saying that the money is for the Leaving Earth hardback.

Please consider donating. Your help will make it possible for me to continue to be an independent reporter in the field of space, science, technology, and culture.

This announcement will remain at the top of the webpage for the rest of this week. Scroll down for new updates and stories.

Islands of ice on Mars and Pluto

November 15, 2019 12:54 pm Robert Zimmerman

Ice-filled craters near Martian south pole

In a paper published today in the Journal of Geophysical Research: Planets, scientists describe the identification of 31 ice-filled craters in the high southern latitudes of Mars. The map to the right, from their paper, shows the locations of these craters. The scientists also took a look at Pluto, and found five craters there that had similar features, though these were likely filled with frozen nitrogen, not water ice.

From their abstract:

These new 31 ice deposits represent an inventory of more than 10 trillion cubic meters of solid water, similar to but greater in number and volume than previously studied features near the north pole. Similar features of nitrogen ice may exist in craters on Pluto, suggesting that craters are a favorable location for the accumulation or preservation of ices throughout the Solar System. [emphasis mine]

These results are reinforced by the existence of glacial features found in numerous Martian craters at much lower latitudes, as well as the ice suspected to exist in the permanently shadowed craters on the Moon and Mercury. The processes that put the ice there on these different planets might be fundamentally different, but the results are the same: Ice accumulating within craters.

One aspect of these high latitude craters that remains somewhat unexplained is their asymmetrical distribution around the south pole, favoring the side of the planet south of Mars’ giant volcanoes. Moreover, in looking at the ice deposits within these craters the scientists found that the ice seemed to lie off-center within the craters, favoring a similar direction.

Based on the available data, the scientists theorize that the most likely cause of this asymmetric off-center pattern is wind. From their paper:

Basic physical arguments, mesoscale atmospheric models, and geomorphological observations predict deflection of winds emanating from the south pole by the Coriolis Force. Such deflection results in a general westward trend of winds (i.e., easterlies) in the south polar regions outside the [south pole cap], matching the [ice-filled crater] offsets we observe.

This correlation implies that wind is important in … formation and/or evolution [of craters with ice]. For the case where winds control [their] formation, katabatic winds may travel down the east side of crater walls and preferentially deposit ice on the west side of the crater via orographic precipitation as they flow up the west crater wall. This mechanism thus favors local accumulation of ice within craters.

I find it fascinating that the location of ice within craters on Mars might indirectly provide scientists with information about the planet’s global weather patterns. This unexpected connection highlights the need to dismiss no data or feature in trying to understand planetary formation. Unlikely things might answer our questions.

Inspector general slams NASA’s management for bonus payments to Boeing

November 15, 2019 10:11 am Robert Zimmerman

In a report [pdf] issued yesterday, NASA’s inspector general blasted the agency’s manned commercial space management for issuing a $287 million bonus payment to Boeing to help it avoid delays in developing its Starliner capsule — which would have caused gaps in future American flights to ISS — even though the cost to use Russian Soyuz capsules would have been far less.

Worse, the agency never even allowed SpaceX to make its own competitive offer.

NASA agreed to pay Boeing Co (BA.N) a $287 million premium for “additional flexibilities” to accelerate production of the company’s Starliner crew vehicle and avoid an 18-month gap in flights to the International Space Station. NASA’s inspector general called it an “unreasonable” boost to Boeing’s fixed-priced $4.2 billion dollar contract.

Instead, the inspector general said the space agency could have saved $144 million by making “simple changes” to Starliner’s planned launch schedule, including buying additional seats from Russia’s space agency, which the United States has been reliant on since the 2011 retirement of its space shuttle program.

…NASA justified the additional funds to avoid a gap in space station operations. But SpaceX, the other provider, “was not provided an opportunity to propose a solution, even though the company previously offered shorter production lead times than Boeing,” the report said. [emphasis mine]

I’ve read the report, and from it the impression is clear that when NASA management discovered that Boeing was facing delays in Starliner and needed extra cash, it decided to funnel that cash to it, irrespective of cost. While it is likely that the agency did so because it did not wish to buy more Russian Soyuz seats, it makes no sense that it didn’t ask SpaceX for its own competitive bid. By not doing so the management’s foolish bias towards Boeing is starkly illustrated

Eric Berger at Ars Technica also notes that the report makes clear how Boeing’s prices for Starliner are 60% higher than SpaceX’s Crew Dragon prices, further illustrating how the agency favors Boeing over SpaceX.

Boeing’s per-seat price already seemed like it would cost more than SpaceX. The company has received a total of $4.82 billion from NASA over the lifetime of the commercial crew program, compared to $3.14 billion for SpaceX. However, for the first time the government has published a per-seat price: $90 million for Starliner and $55 million for Dragon. Each capsule is expected to carry four astronauts to the space station during a nominal mission.

What is notable about Boeing’s price is that it is also higher than what NASA has paid the Russian space corporation, Roscosmos, for Soyuz spacecraft seats to fly US and partner-nation astronauts to the space station. Overall, NASA paid Russia an average cost per seat of $55.4 million for the 70 completed and planned missions from 2006 through 2020. Since 2017, NASA has paid an average of $79.7 million.

I don’t have a problem with NASA favoring Boeing over Russia, considering the national priorities. I can also understand the agency’s willingness to keep buying some Starliner seats in order to guarantee an American launch redundancy. However, giving Boeing even more money to keep its schedule going, when SpaceX is available to fill the gaps, demonstrates the corruption in the agency’s management. They haven’t the slightest understanding of how private enterprise and competition works.

The report is also filled with the same tiresome complaints about the on-going delays to the manned commercial program, focusing greatly on past technical issues (now mostly solved) while hiding in obscure language how it is NASA’s paperwork that is likely to cause all further delays.

Shashi Tharoor – Is Your Vocabulary Up to Mark?

November 14, 2019 6:01 pm Robert Zimmerman

An evening pause: This is entertaining, in that it demonstrates the ability of English to absorb an endless number of words, even words that are absolutely ridiculous. Most of these words are unknown because they are hard to say and their meaning can be stated more efficiently and simply using normal vocabulary. I must also add that Tharoor is a Indian politician from the socialist Congress Party, now the minority party in India with the rise the present conservative government under President Modi.

I am therefore not surprised that he is skilled with using big words that can help him obfuscate his meaning, while making him seem erudite.

The dance of two Neptunian moons

November 14, 2019 1:26 pm Robert Zimmerman

Scientists have discovered that the orbital interplay between two of Neptune’s moon keep them close together but never touching. Instead, they dance about each other.

In this perpetual choreography, Naiad swirls around the ice giant every seven hours, while Thalassa, on the outside track, takes seven and a half hours. An observer sitting on Thalassa would see Naiad in an orbit that varies wildly in a zigzag pattern, passing by twice from above and then twice from below. This up, up, down, down pattern repeats every time Naiad gains four laps on Thalassa.

Although the dance may appear odd, it keeps the orbits stable, researchers said.

I have embedded below the fold a video that illustrates this.

A journey into the depths of Valles Marineris

November 14, 2019 1:20 pm Robert Zimmerman

Valles Marineris

Cool image time! Rather than start with the cool image, let’s begin with the long view. To the right is a wide mosaic of Valles Marineris on Mars, the largest known canyon in the solar system. About 2,500 miles long and 400 miles wide, this canyon is so large that it would cover most of the United States if put on Earth. The Grand Canyon, 500 miles long by 19 miles wide, could easily fit within it and not be noticed. In depth Valles Marineris is equally impressive, with a depth of more than four miles, about four times deeper than the Grand Canyon.

A closer view of the central regions of Valles Marineris

The white cross in the mosaic above is where we are heading. You can see it as the white box in the zoomed in overview to the right. This central part of Valles Marineris is named East Melas Chasma, and the red boxes indicate locations where the high resolution camera of Mars Reconnaissance Orbiter (MRO) has already taken images.

As you can see, we do not yet have many high resolution images of this part of the canyon floor. The white box is the most recent image, and is the subject of today’s post.

Celebrating Apollo 12

November 14, 2019 12:02 pm Robert Zimmerman

Click for the full resolution image.

Fifty years ago today Apollo 12 was launched, landing on the Moon several days later to become the second manned mission to land on another world.

To celebrate that achievement, let’s review a few of the mission’s high points. The image to the right, cropped and reduced to post here, shows that landing site, the lunar module Intrepid, the various tracks for the two moon-walks Pete Conrad and Alan Bean took, and the unmanned Surveyor-3 probe. The image was taken by Lunar Reconnaissance Orbiter late in 2011 and released to the public in 2012. To really see some detail you will look at the full resolution version by clicking on the image. Or you can explore the landing even more thoroughly at the original release site.

First, there was Pete Conrad’s point blank landing. They wanted to land close enough to Surveyor 3 so that the two astronauts would be able to walk over to it during a spacewalk. He did this perfectly, bringing Intrepid down only 600 feet away. They were thus able to recover the probe’s scoop, camera, television cable, and other assorted parts. Once back on Earth the big discovery was that a single bacterium, Streptococcus mitis, had survived the journey from Earth and was still alive upon its return. Scientists theorized its survival occurred because prior to launch it had been freeze-dried during prelaunch vacuum tests.

Second, there were Pete Conrads’s first words upon stepping off the lunar module. As the third man to walk on the Moon and also one of the shortest Apollo astronauts, he won a bet with a French reporter, who did not believe he had the freedom to say whatever he wanted as his first words, by saying, “Whoopee! Man, that may have been a small step for Neal, but it’s a long one for me!”

Third, the astronauts installed the second seismometer on the Moon, which functioned for eight years.

Fourth, they brought back 75 pounds of material, which showed that while the Ocean of Storms was a mare lava field like the Sea of Tranquility, it had formed 500 million years more recently.

Fifth and most important, Apollo 12 proved that the Apollo 11 landing was not a fluke, that the engineering behind the Saturn 5 rocket, the Apollo capsule, and the lunar module, was sound. With courage and determination and a little clever re-engineering, those vehicles had been capable of taking humans anyway in the solar system. It is a shame we never took advantage of that possibility.

Upcoming big satellite constellations vex and worry astronomers

November 14, 2019 10:33 am Robert Zimmerman

Astronomers are expressing increasing distress over the possible negative consequences to their Earth-based telescope observations from the several new giant satellite constellations being launched by SpaceX and others.

[M]any astronomers worry that such ‘megaconstellations’ — which are also planned by other companies that could launch tens of thousands of satellites in the coming years — might interfere with crucial observations of the Universe. They fear that megaconstellations could disrupt radio frequencies used for astronomical observation, create bright streaks in the night sky and increase congestion in orbit, raising the risk of collisions.

The Nature article then details the issues faced by some specific telescopes. Hidden within the article however was this interesting tidbit that admitted the problem for many telescopes is really not significant.

Within the next year or so, SpaceX plans to launch an initial set of 1,584 Starlink satellites into 550-kilometre-high orbits. At a site like Cerro Tololo, Chile, which hosts several major telescopes, six to nine of these satellites would be visible for about an hour before dark and after dawn each night, Seitzer has calculated.

Most telescopes can deal with that, says Olivier Hainaut, an astronomer at the European Southern Observatory (ESO) in Garching, Germany. Even if more companies launch megaconstellations, many astronomers might still be okay, he says. Hainaut has calculated that if 27,000 new satellites are launched, then ESO’s telescopes in Chile would lose about 0.8% of their long-exposure observing time near dusk and dawn. “Normally, we don’t do long exposures during twilight,” he says. “We are pretty sure it won’t be a problem for us.” [emphasis mine]

The article then proceeds with its Chicken-Little spin as if the astronomical world is about to end if something is not done to stop or more tightly control these new satellite constellations.

As indicated by the quote above, it appears however that the threat is overstated. The constellations might reduce observing time slightly on LSST, scheduled for completion in 2022 and designed to take full sky images once every three nights. Also, the satellite radio signals might impact some radio astronomy. In both cases, however, the fears seem exaggerated. Radio frequencies are well regulated, and LSST’s data should easily be able to separate out the satellite tracks from the real astronomical data.

Rather than demand some limits or controls on this new satellite technology, the astronomical community should rise to the occasion and find ways to overcome this new challenge. The most obvious solution is to shift the construction of new telescopes from ground-based to space-based. In fact, this same new satellite technology should make it possible for them to do so, at much less cost and relatively quickly.

But then, astronomers are part of our modern academic community, whose culture is routinely leftist and therefore fascist in philosophy (even though they usually don’t realize it). To them too often the knee-jerk response to any competition is to try to control and squelch it.

We shall see if the astronomers succeed in this case.

Both methane and oxygen fluctuate in unison seasonally in Gale Crater

November 14, 2019 10:04 am Robert Zimmerman

The uncertainty of science: According to a new science paper, data from Curiosity on Mars has now found that both methane and oxygen fluctuate in unison seasonally in Gale Crater.

From the paper’s abstract:

[T]he annual average composition in Gale Crater was measured as 95.1% carbon dioxide, 2.59% nitrogen, 1.94% argon, 0.161% oxygen, and 0.058% carbon monoxide. However, the abundances of some of these gases were observed to vary up to 40% throughout the year due to the seasonal cycle. Nitrogen and argon follow the pressure changes, but with a delay, indicating that transport of the atmosphere from pole to pole occurs on faster timescales than mixing of the components. Oxygen has been observed to show significant seasonal and year‐to‐year variability, suggesting an unknown atmospheric or surface process at work. These data can be used to better understand how the surface and atmosphere interact as we search for signs of habitability.

The data shows that the unexpected and so far unexplained seasonal oxygen fluctuation appears to track the same seasonal methane fluctuations. While biology could cause this signature, so could geological processes, though neither can produce these fluctuations easily.

Meanwhile, adding to the uncertainty were results from the two European orbiters, Mars Express and Trace Gas Orbiter. Both have failed to detect a June 19, 2019 dramatic spike in methane that had been measured by Curiosity.

China unveils Mars lander during landing simulation test

November 14, 2019 9:44 am Robert Zimmerman

The new colonial movement: China today unveiled to the international press its first prototype Mars lander, showing it attempting a simulated controlled descent on a gigantic test stand.

The demonstration of hovering, obstacle avoidance and deceleration capabilities was conducted at a site outside Beijing simulating conditions on the Red Planet, where the pull of gravity is about one-third that of Earth.

China plans to launch a lander and rover to Mars next year to explore parts of the planet in detail.

This is the first time I have heard anything about China sending a lander/rover to Mars in 2020. Previously the reports had discussed only sending an orbiter.

I have embedded video of the test below the fold. It shows the prototype hanging by many wires from the test stand, then dropping quickly, with its engine firing, before stopping suddenly, followed by an engine burst. While impressive, it did not strike me that China is even close to sending this spacecraft to Mars. The test only proved the spacecraft’s ability to do some maneuvering during descent. It did not show that it could land.

That the project’s designer said that landing would take “about seven minutes” also suggests that they are copying the techniques used by JPL to land Curiosity. Considering that JPL’s computers have been repeatedly hacked, including some hacks identified as coming from China, it would not surprise me if China has simply stolen those techniques.

I still expect them to launch an orbiter to Mars in 2020. Whether they also send a lander and rover remains to be seen.

India targets Nov 2020 for new lunar lander mission

November 14, 2019 9:24 am Robert Zimmerman

The new colonial movement: Sources inside India’s space agency ISRO yesterday revealed that they are now working to build and fly another lunar lander/rover, dubbed Chandrayaan-3, with a target launch date of November 2020, only one year from now.

Isro has formed multiple committees — an overall panel and three sub-committees — and held at least four high-level meetings since October. The new mission will include only a lander and rover, as the Chandrayaan-2 orbiter is functioning well. On Tuesday, the overview committee met with the agenda of reviewing the configuration of Chandrayaan-3. It also looked into the recommendations of various sub-committees on propulsion, sensors, overall engineering, navigation and guidance.

The Chandrayaan-2 orbiter had provided the propulsion capabilities to get the Vikram lander (with rover) to lunar orbit earlier this year, only to have the lander fail shortly before touchdown. To do this new mission without an orbiter will require adding a propulsion unit to the rover/lander. They are also looking at strengthening the lander’s legs to better resist a high velocity landing.

Kudos to ISRO for moving so quickly. There is no reason a replacement lander/rover should take years to build. They already know what to do, they need only do it again, with upgrades designed to avoid the failure in September.

SpaceX completes Crew Dragon static fire tests

November 14, 2019 9:14 am Robert Zimmerman

SpaceX yesterday successfully completed a static fire engine test of its Crew Dragon capsule, demonstrating that it has fixed the issues that caused the April 20th explosion during an earlier test that destroyed a capsule.

Wednesday’s test occurred just 207 days after the April anomaly, a quick turnaround time given the complexity of the systems at hand. The incident earlier this year occurred just milliseconds before the engines were to have ignited, and was eventually traced to valves leaking propellant into high-pressure helium lines.

SpaceX made numerous changes to Crew Dragon as a result of the anomaly, including the replacement of the valves with burst-discs. The company has also been performing several smaller-scale tests of the redesigned system at their test facility in McGregor, Texas. Last month, SpaceX Tweeted a video of one such test.

Wednesday’s test was the first full-scale firing of all eight of Crew Dragon’s SuperDraco’s at once since the April incident.

This success clears the way for the launch abort test using this same capsule, now tentatively scheduled for mid-December.

SpaceX completes 1st round of Starship’s Mars landing site images

November 13, 2019 1:31 pm Robert Zimmerman

All locations photographed of the candidate landing region for SpaceX's planned Mars missions

On August 28, 2019 I broke the story that SpaceX is beginning to obtain images of candidate Starship landing sites from Mars Reconnaissance Orbiter (MRO).

It now appears that SpaceX has completed its first round of Starship requests from MRO. In the image releases from Mars Reconnaissance Orbiter (MRO) since September, only three new Starship locations were taken, and all three were the unreleased candidate sites I noted in my September 16, 2019 update.

Below is the full list of all of the Starship images, their locations indicated on the map above by the numbered white boxes:

With the release of these last photographs, the initial list of proposed images of candidate Starship landing sites on Mars has apparently been completed. No additional images at any other locations appear to have been suggested. The MRO science team has taken stereo images of each one of the nine locations, eight of which were in Amazonis Planitia, and one in Phlegra Montes.

This however is not the first round of pictures requested by SpaceX of the Arcadia Planitia region in connection with the company’s desire to land spacecraft on Mars.

Hayabusa-2 begins journey back to Earth

November 13, 2019 9:32 am Robert Zimmerman

The Hayabusa-2 science team has fired up the spacecraft’s ion engine to leave the asteroid Ryugu and began its begins journey back to Earth.

It will take about six days to exit the gravitational sphere of influence of Ryugu. During that time period they will be continually releasing real time images of the asteroid from the spacecraft’s navigation camera, as it slowly gets farther away.

In mid-December they will fire the spacecraft’s main engines for an arrival near Earth in late 2020. At that point the small return capsule holding the samples from Ryugu will separate and land in the Australian desert. Hayabusa-2, still operational, might then be given a new subsequent mission.

Virgin Galactic reports first loss since stock went public

November 13, 2019 9:19 am Robert Zimmerman

Capitalism in space: Virgin Galactic today released its first quarterly report since the company’s stock went public in October, reporting a net loss of $51.5 million during the third quarter of 2019.

The stock initially opened in October at $12.93. It quickly dropped 25% in value, and has generally been trading at about $10 a share since. With today’s release the stock immediately dropped below $10, but it appears to have settled at around $9.75, for the moment.

According to this story, they presently have reservations from 600 people for suborbital flights, and have received 3,557 inquiries about flight reservations as of the end of September.”

No manned New Shepard flights in 2019

November 13, 2019 8:57 am Robert Zimmerman

In an interview with CNBC, Bob Smith, the CEO of Blue Origin, revealed that the first manned flights of New Shepard will not take place in 2019, as previously predicted.

Smith: We were planning on this year; unfortunately, it’s very unlikely we’re going to get in this year. We need a few more flights to make sure that we’re all comfortable with the verification. We hold ourselves to very, very high standards here, we’re never going to fly until we’re absolutely ready. I think we have a very, very good amount of confidence around the system itself, I think it is working very, very well. But we have to go look at all the analysis, and then convince ourselves that we’re ready to go. … So it probably will be next year.

This statement confirms what Smith said in late September. However, though he says they need to do a few more unmanned test flights, they have not done one since May, suggesting there was some issue during that last flight that they aren’t telling us about.

The interview overall contains little concrete information, and in fact suggests that the company’s orbital rocket, New Glenn, is likely not going to meet its 2021 launch target. When asked when he expects their rocket factory in Huntsville to begin building 40 engines a year, he said, “when we are at-rate and flying, so in ’22 and ’23. We are opening the factory there this coming first quarter.”

That 2021 date was a delay of a year from the original goal of 2020. That they won’t be opening their rocket factory until 2020, and won’t be operational until 2022 or 2023, suggests this entire schedule is out the window. I will not be surprised if there are no New Glenn flights before 2023.

Polygons on Mars

Cool image time! The photograph on the right, cropped to post here, was taken on September 25, 2019 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and made public in its November image release. It shows the weird but very typical scalloped terrain, with its adjacent polygon pattern of fractures, found routinely in the northern lowland plains of Utopia Planitia on Mars. From an earlier captioned image from 2006 of these same features:

The scalloped depressions are typical features; a smooth layered terrain located between 40 and 60 degrees in both hemispheres. Scalloped depressions probably form by removal of ice-rich subsurface material by sublimation (ice transforming directly from a solid to a gaseous state), a process that may still be active today. Isolated scalloped depressions generally have a steep pole-facing scarp and a gentler equator-facing slope. This asymmetry is interpreted as being the result of difference in solar heating. Scalloped depressions may coalesce, leading to the formation of large areas of pitted terrain.

The polygonal pattern of fractures resembles permafrost polygons that form in terrestrial polar and high alpine regions by seasonal-to-annual contraction of the permafrost (permanently frozen ground). On Earth, such polygons indicate the presence of ground ice.

On Earth these polygons are most often seen in mud, usually suggesting a drying process where the ground contracts with the lose of fluid. On Mars the cracks probably also form from contraction, but not by the lose of fluid but the lose of water ice as it sublimates into a gas.

These polygons and scallops illustrate an important feature of Mars’ vast northern plains. On large scales these plains appear flat and featureless. Up close however many many strange features, like the polygons and scallops in this image, come into view.

New Horizons team renames “Ultima Thule” to “Arrokoth”

November 12, 2019 12:57 pm Robert Zimmerman

The New Horizons team has renamed the Kuiper Belt object that the spacecraft flew past on January 1, 2019 from its informal nickname of “Ultima Thule” to “Arrokoth,” which means “sky” in Powhatan/Algonquian language.

This official, and very politically correct, name has apparently gotten the stamp of approval from the IAU.

In accordance with IAU naming conventions, the discovery team earned the privilege of selecting a permanent name for the celestial body. The team used this convention to associate the culture of the native peoples who lived in the region where the object was discovered; in this case, both the Hubble Space Telescope (at the Space Telescope Science Institute) and the New Horizons mission (at the Johns Hopkins Applied Physics Laboratory) are operated out of Maryland — a tie to the significance of the Chesapeake Bay region to the Powhatan people.

“We graciously accept this gift from the Powhatan people,” said Lori Glaze, director of NASA’s Planetary Science Division. “Bestowing the name Arrokoth signifies the strength and endurance of the indigenous Algonquian people of the Chesapeake region. Their heritage continues to be a guiding light for all who search for meaning and understanding of the origins of the universe and the celestial connection of humanity.” [emphasis mine]

It is a good name, especially because its pronunciation is straight-forward, unlike the nickname.

The blather from Glaze above, however, is quite disingenuous. The Algonquian people have had literally nothing to do with the modern scientific quest for “meaning and understanding of the origins of the unverse.” They were a stone-age culture, with no written language. It was western civilization that has made their present lives far better. And it was the heritage of western civilization, not “the indigenous Algonquian people” that made the New Horizons’ journey possible. Without the demand for knowledge and truth, as demanded by western civilization, we would still not know that Arrokoth even existed.

Astronomers discover star fleeing Milky Way at 3.7 million mph

November 12, 2019 12:46 pm Robert Zimmerman

Astronomers have discovered a star that rocketing out of the Milky Way at 3.7 million miles per hour because five million years ago it made a close approach to Sagittarius A* (prounounced “A-star”), the super-massive black at the center of the galaxy.

“The velocity of the discovered star is so high that it will inevitably leave the Galaxy and never return”, said Douglas Boubert from the University of Oxford, a co-author on the study.

Astronomers have wondered about high velocity stars since their discovery only two decades ago. S5-HVS1 is unprecedented due to its high speed and close passage to the Earth, “only” 29 thousand light years away. With this information, astronomers could track its journey back into the centre of the Milky Way, where a 4 million solar mass black hole, known as Sagittarius A*, lurks.

Almost certainly there are many such stars. They are just hard to spot.

Putin slams Roscosmos for continuing corruption at Vostochny

November 12, 2019 8:22 am Robert Zimmerman

At a meeting yesterday Russian President Vladimir Putin blasted Roscosmos for the corruption at the new spaceport at Vostochny, noting that despite the prosecution of numerous individuals the criminal behavior continues.

Russian President Putin said at a government meeting on Monday that dozens of criminal cases and jailings had failed to stem theft at the Vostochny spaceport construction site….

“It has been stated a hundred times: you must work transparently because large funds are allocated. This project is actually of the national scope! But, despite this, hundreds of millions, hundreds of millions [of rubles] are stolen! Several dozen criminal cases have been opened, the courts have already passed verdicts and some are serving their prison terms. However, things have not been put in order there the way it should have been done,” the Russian president said.

This article notes that out of $1.4 billion allocated for the spaceport, $169 million has been stolen. It does not however provide any details about any new corruption. Instead, it outlines the investigations and prosecutions that have already taken place.

According to Peskov, “at the first stage, 128 criminal cases were opened, which were later consolidated into 32 criminal cases and at the next stage the Investigative Committee singled out 21 cases and transferred them to the court of law and 18 persons were sentenced at the time,” Peskov said. “The Interior Ministry investigated 8 more cases,” he added.

Either Roscosmos officials revealed to Putin newly discovered corruption that the state-run press has been forbidden to discuss, or Putin’s criticism was aimed to discouraging future corruption.

Either way, Vostochny remains a typical government boondoggle. It has cost Russia far more than it should, and construction has been slow, beginning officially in 2012, though Russia has been working on it in fits and starts since the mid-2000s.
