At a conference today
Posting will be intermittent, as I am attending a one day conference [pdf] at the University of Arizona being put on by Lunar & Planetary Laboratory.
Tidbits posted as I hear them (these tidbits do not involve new results that are still embargoed):
-Data from OSIRIS-REX at Bennu and Hayabua-2 at Ryugu have found that while both are rubble pile asteroids, there is evidence that suggests that Ryugu, but not Bennu, was subjected to heating in the past. In other words, it had been cooked.
-We presently possess no meteorites with a chemical make-up that matches the data obtained from orbit around Mercury. This isn’t a surprise, as any material thrown from the surface by an impact would not likely have the energy and velocity required to climb up out of the Sun’s gravitation well and get to Earth. Material from Mars however can easily fall into that well, which is why it is not difficult to find meteorites from Mars on Earth.
– Unlike the Earth, where atmospheric circulation in the north and south hemispheres is independent, Titan’s atmosphere is actually one large Hadley Cell, with flow going from one hemisphere to the other, depending on season.
-The evolutionary changes in Neptune’s orbit over time is thought to have caused the high inclination orbits seen in the objects in the Kuiper Belt, which are a mystery since all these objects must have once been confined within the protoplanetary disk, today’s plane of the solar system.
-Despite finding thousands of candidate exoplanets, Kepler found none in the habitable zone. This does not mean habitable exoplanets are rare, but that there were certain biases in Kepler’s observations that caused this lack.
-There is a lot of research going on to study buried ice/glaciers here on Earth. This work is directly aimed at better understanding the many buried glaciers now thought to exist on Mars.

Results from tiny MASCOT lander on Ryugu
The scientists in charge of the tiny MASCOT lander dropped from Japan’s Hayabusa-2 spacecraft today released the results from the lander’s short seventeen hour observations of the surface of Ryugu.
They found that the asteroid has two different types of rocks (why is a mystery) and practically no dust.
Ralf Jaumann and his team were particularly surprised by the lack of dust: “Ryugu’s entire surface is littered with boulders, but we have not discovered dust anywhere. It should be present, due to the bombardment of the asteroid by micrometeorites over billions of years, and their weathering effect. However, as the asteroid has very low gravity – only one-sixtieth of that experienced on Earth’s surface – the dust has either disappeared into cavities on the asteroid or has escaped into space. This gives an indication of the complex geophysical processes occurring on the surface of this small asteroid.”
They also confirmed that the asteroid is a very fragile rubble pile.
“If Ryugu or another similar asteroid were ever to come dangerously close to Earth and an attempt had to be made to divert it, this would need to be done with great care. In the event that it was impacted with great force, the entire asteroid, weighing approximately half-a-billion tonnes, would break up into numerous fragments. Then, many individual parts weighing several tonnes would impact Earth,” says Jaumann, who is supervising the MASCam experiment, interpreting the observations. The asteroid is very similar to carbonaceous meteorites found on Earth, which date back 4.5 billion years. With an average density of just 1.2 grams per cubic centimetre, Ryugu is only a little ‘heavier’ than water ice. But as the asteroid is made up of numerous pieces of rock of different sizes, this means that much of its volume must be traversed by cavities, which probably makes this diamond-shaped body extremely fragile.
MASCOT was another example of a cubesat demonstrating that these tiny spacecraft can do very sophisticated science.

Melting rocks on Mars
Click for full image.
Cool image time! The image to the right, reduced, cropped, and annotated by me to post here, was part of the July image download from the high resolution camera on Mars Reconnaissance Orbiter (MRO) and was titled “Melt Pools around Mojave Crater”.
You can see that the flow began to the south, flowed northward (in the middle of the image), and then pooled in the two places as indicated. In the full photograph you can also see that the flow continued to the north, forming more pools.
The title to me suggests that this flow and the melt pools were lava, not ice. The low latitude, 7 degrees north, also suggests this is not ice. Though I was unable to reach the person who requested these images, it appears his research is aimed understanding the melt events that occur in the vicinity of craters upon impact. From his website:

Japan’s plan for returning Hayabusa-2’s Ryugu samples to Earth
Japan’s today provided an update on what it has done to prepare the location where Hayabusa-2’s samples from the asteroid Ryugu will land on Earth.
The landing site is in the Woomera Prohibited Area (WPA) in the outback of southern Australia. Japan has already signed an agreement with that country for the recovery, as well as done preliminary surface work
The recovery site is an Australian Government prohibited area and is not accessible to the public. As part of the preparatory work, a field survey of the proposed recovery site in the WPA was conducted with permission from the Australian Government. This preparatory work confirmed the suitability of both the proposed recovery site and the candidate site for the antenna station that will search for the capsule.
The landing of the recovery capsule is now scheduled for late in 2020.

Sierra Nevada unveils full scale Gateway habitat module prototype
Capitalism in space: Sierra Nevada yesterday unveiled a full scale prototype of a habitable module that it developed under a NASA contract for the agency’s proposed Lunar Gateway space station.
[The module] measures more than 8 meters long, and with a diameter of 8 meters has an internal volume of 300 cubic meters, which is about one-third the size of the International Space Station.
Sierra Nevada developed this full-scale prototype under a NASA program that funded several companies to develop habitats that could be used for a space station in orbit around the Moon, as well as potentially serving as living quarters for a long-duration transit to and from Mars. As part of the program, NASA astronauts have, or will, spend three days living in and evaluating the prototypes built by Sierra Nevada, Boeing, Lockheed Martin, Northrop Grumman, and Bigelow Aerospace.
The selling point for Sierra Nevada’s habitat is its size, which is possible because the multi-layered fabric material can be compressed for launch, then expanded and outfitted as a habitat once in space. It can fit within a standard payload fairing used for launch vehicles such as SpaceX’s Falcon Heavy rocket, United Launch Alliance’s Vulcan booster, or NASA’s Space Launch System. It is light enough for any of those rockets to launch to the Moon.
What we are seeing here is the unfolding of the Washington lobbying game to guarantee Gateway gets funded and built. NASA is spreading its available Gateway cash around to multiple companies, who will now have a vested interest in lobbying Congress to get this lunar space station funded and built.
The one very good component of this lobbying process is that NASA is not doing the building or the designing. It is hiring private companies, which means the project will act to stimulate the American aerospace industry. Moreover, it is leaving the ownership of the spacecraft and the decision on what launch vehicle to use to the companies, which means this cannot be used as a lever to fund the SLS boondoggle. Under this arrangement more will get done faster for less.
Even so, Lunar Gateway will mostly act to slow the United States’ effort to colonize the solar system. We will be spending our government space dollars on an orbiting lunar space station, thus generally trapping us in orbit, as we watch China, India, Russia and others land and explore the surface.
There is only one way Gateway could possibly be beneficial to the United States. NASA gets it built fast and cheaply, so that it then can be used as a jumping off point for further exploration. This would give the U.S. capabilities in space that far exceed other countries.
My fear is that NASA has a terrible track record in the past half century of doing anything fast or cheaply. Instead, NASA projects like Gateway end up taking forever and costing many times their initial proposed budget. SLS is a perfect poster child for this. Its goal is not so much to launch as to provide Congress endless pork.

China successfully tests navigation in space using pulsars
Using the X-ray space telescope Insight it launched in 2017, China has successfully tested an autonomous navigation system using pulsars.
The time interval of two adjacent pulses emitted by the pulsar is constant. If a spacecraft moves toward the pulsar, the received pulse interval will be shortened, and vise versa. Thus the observed pulse profile will change as the spacecraft moves in space. The relative arrival times of pulses also indicate the relative position of the spacecraft with respect to the pulsar. Therefore, by analyzing the characteristics of the pulsar signals received by the spacecraft, the three-dimensional position and velocity of the spacecraft can be determined, Zheng explained.
From Aug. 31 to Sept. 5, 2017, Insight observed the Crab pulsar for about five days to test the feasibility of pulsar navigation. The research team had also proposed an algorithm for X-ray pulsar navigation, according to Zhang Shuangnan, lead scientist of the Insight space telescope.
The research team further improved the algorithm and applied it in the processing of the observation data of the three detectors onboard Insight. The satellite’s orbit was determined successfully, with the positioning accuracy within 10 km, comparable to that of a similar experiment conducted on the International Space Station, Zhang said.
This is not the first such test. U.S. scientists did something similar using an X-ray telescope on ISS in 2017.

ISRO releases Chandrayaan-2’s first Moon image from lunar orbit
India’s space agency ISRO has released the first image taken by Chandrayaan-2 after entering orbit around the Moon.
That image is to the right, reduced to post here. It was taken from about 1,600 miles elevation, and shows mostly the far side of the Moon. The dark mare in the upper right is the Sea of Moscow, which is the only large mare on the far side.
This image once again proves the camera and the spacecraft’s ability to point it accurately are both functioning.

Russia and ULA successfully complete rocket launches
Russia and ULA both successfully placed spacecraft into Earth orbit today.
Russia sent an unmanned upgrded Soyuz capsule to ISS, filled with cargo, in a test flight that also tested a new upgraded version of the Soyuz rocket.
According to Navias, this Soyuz launch is a critical shakedown flight to test the performance of the upgraded Soyuz capsule and the Soyuz 2.1a booster before the first crewed flight on the rocket in March 2020.
“The Soyuz 2.1a booster, equipped with a new digital flight control system and upgraded engines, is replacing the Soyuz FG booster that has been used for decades to launch crews into space,” NASA officials wrote in a statement. “The Soyuz spacecraft will have an upgraded motion control and navigation system, as well as a revamped descent control system,” they added.
The mission will also help Roscosmos develop a cargo version of the Soyuz capsule capable uncrewed reentry to return experiments and other gear to Earth, Navias said. Russia’s Progress cargo ships can currently only deliver supplies, and are filled with trash and discarded at the end of their missions.
ULA in turn launched an Air Force GPS satellite in the last launch of the Delta-4 Medium version of its Delta rocket family.
The leaders in the 2019 launch race:
13 China
13 Russia
10 SpaceX
6 Europe (Arianespace)
4 India
4 Rocket Lab
4 ULA
The U.S. leads Russia and China 19 to 13 in the national standings.

Congressional Budget Office: Budget deficits about to explode
The Congressional Budget Office (CBO) released a new budget analysis today that predicts the federal budget will see trillion dollar annual deficits for years to come, based on present government spending.
The Congressional Budget Office (CBO) released a grim update Wednesday to its economic outlook for the next decade, predicting average national deficits of $1.2 trillion every year through 2029, due in large part to recent budget and border security bills.
The CBO report noted that, as one of many repercussions from free-spending policies, federal debt held by the public is projected to reach heights not seen since the 1940s, almost equaling the nation’s Gross Domestic Product. “As a result of those deficits, federal debt held by the public is projected to grow steadily, from 79 percent of GDP in 2019 to 95 percent in 2029—its highest level since just after World War II,” the report says. The GDP itself is also expected to see a slowdown in growth in the coming years.
The CBO report underscores how deficits are rising once again, as Democrats and Republicans in Congress — and the Trump administration — show little interest in tackling the red ink. [emphasis mine]
Trump is not breaking any promises in doing nothing to restrain spending. He has never shown much interest in reducing the deficit, and in fact has often appeared eager to spread government cash around freely.
The Republicans in Congress however have repeatedly campaigned on a platform of fiscal responsibility. They have also repeatedly proven that platform to be an outright lie. Once elected they have routinely spent money as willingly as the Democrats, and the new budget bill recently agreed to by Congress and Trump underscored this, as they went along with a deal that removed all the restraints of sequestration that had helped limit budget growth for the past six years.

2018 Hot Rod Wild Rides
An evening pause: A breath-taking collection of crashes and failures during the 2018 National Hot Rod Association race season One could call this a collection of engineering failures, but I don’t see it that way. For one, absolutely no one was seriously hurt, proving the design of their safety features. For another, the engine failures show how they are pushing the engineering to the max to win.

Washington’s spectacular effort to crush the American space effort
Three stories today illustrate once again the incompetence, idiocy, and inability of practically anyone in our federal government to get anything done sanely and efficiently and with success.
In the past half century that federal government has saddled the American people with a debt that is crushing. In that time it has also failed to do its job of properly enforcing the law to control the borders. It has spent trillions on social problems, only to have those social problems worsen exponentially.
I could go on. The problems imposed on American society by our failed ruling class in Washington since the 1960s is myriad. In the area of aerospace and space exploration, my specialty, the following three stories today alone demonstrate again that continuing track record, with no sign that anyone in Washington recognizes how bad a job they are doing.
- NASA Has Committed to a Rocket for the Europa Mission—and It Won’t Be Ready on Time
- The government’s plan to update rocket launch licensing is pissing off the commercial space industry
- Tectonic Shift As NRO Moved Under Space Command In Wartime
First we have incompetence and idiocy by Congress. The first story outlines how our sainted lawmakers have mandated by law that the Europa Clipper mission to Jupiter’s moon must fly on NASA’s SLS rocket and “launch no later than 2023.”
This legal requirement, written into the appropriations bill, was imposed because the SLS project is being managed from Alabama, and Senator Richard Shelby (R-Alabama) wants that rocket to get some work to justify this pork to his state. The requirement was further pushed by former Texas Congressman John Culbertson, who has a special place in his heart for Europa, and has specifically imposed that mission on NASA.
Shelby’s demand is especially egregious and makes little sense. First, even after twenty years of effort, NASA will likely not have that rocket available in 2023. Second, the cost to use SLS is about $4 billion per launch (not the fake $1 billion number cited in the article). A Falcon Heavy rocket could do the job for $100 million, which would more than pay for the extra operating costs incurred because it will take the three more years to get to Jupiter.
To deal with this conflict, NASA is presently doing as much lobbying as it can to get Congress to change the time limit, or to allow them to fly the spacecraft on a Falcon Heavy. Not surprisingly, Congress is resisting, even though their position makes no sense and will likely cost the taxpayer billions unnecessarily while likely delaying or even impeding the mission itself.
The article as usual for the mainstream press is filled with misconceptions and errors that are all designed to make any change in this Congressional act seem a mistake. These mistakes were all fed to the reporter by the powers in and out of Congress who oppose changing things, and the reporter sadly was not informed enough to realize this.
Next we have the incompetent and power-hungry federal bureaucracy, as described in the second article.

Scientists resolve one Mars methane mystery
Scientists have now figured out why the methane data from Curiosity on the Martian surface did not match the methane data from Trace Gas Orbiter in orbit around Mars.
Last year, scientists learned that methane concentrations changed over the course of the seasons with a repeatable annual cycle. “This most recent work suggests that the methane concentration changes over the course of each day,” Dr Moores said. “We were able – for the first time – to calculate a single number for the rate of seepage of methane at Gale crater on Mars that is equivalent to an average of 2.8 kg per Martian day.”
Dr Moores said the team was able to reconcile the data from the ExoMars Trace Gas Orbiter and the Curiosity Rover, which appeared to contradict each other with wildly different detections of methane. “We were able to resolve these differences by showing how concentrations of methane were much lower in the atmosphere during the day and significantly higher near the planet’s surface at night, as heat transfer lessens,” he said.
Solving that data conflict helps them get a better grip on the real question: Why is the methane fluctuating in this manner?

SpaceX’s Tesla has completed its first solar orbit
Capitalism in space: The first privately launched car, a Tesla placed in solar orbit on SpaceX’s first launch of its Falcon Heavy, has now completed its first orbit around the sun.
Its future?
Car and driver will probably make many more laps around our star. Last year, an orbit-modeling study calculated that the Roadster will eventually slam into either Venus or Earth, likely within the next few tens of millions of years. But there’s just a 6 percent chance of an Earth impact, and a 2.5 percent chance of a Venus impact, within the next million years, the study’s authors found.

Chandrayaan-2 completes first lunar orbit adjustment
Chandrayaan-2 today made its first engine burn while in lunar orbit, reducing the orbit’s apolune (its high point) down to 4,412 kilometers from 18,072 kilometers.
Three more orbital adjustments to go before they enter the required orbit for landing.

How Google bought off Senator Mike Lee (R-Utah)
Link here. The facts are very damning, and illustrate once again that no matter how much these politicians claim they are there to clean up Washington, you cannot trust them. They can be bought, as Lee has been.
In 2011 and 2012 he was very opposed to the consolidation of the internet industry into the hands of a few companies like Google. Now, after receiving a lot of campaign support from Google, he is their biggest defender.
But today, as he presides as chairman of the Senate antitrust panel, Lee’s stance couldn’t be more different. With critics on both sides of the political aisle assailing big tech, Lee has questioned the need for congressional antitrust investigations, complained about big fines imposed on Google, and defended the tech industry against Republican charges of liberal bias.
From “strong concerns about Google’s…predominant position” to “Antitrust is not the answer”
Most recently, when the DOJ announced its own broad antitrust review of the leading online platforms in July 2019, Lee seemed to shrug, focusing not on the behavior of the tech companies, but on what he called the “institutional tug-of-war” between the Justice Department and the FTC.
Time to primary this former Tea Party conservative, now a Google shill bought and paid for.
Link here. The facts are very damning, and illustrate once again that no matter how much these politicians claim they are there to clean up Washington, you cannot trust them. They can be bought, as Lee has been.
In 2011 and 2012 he was very opposed to the consolidation of the internet industry into the hands of a few companies like Google. Now, after receiving a lot of campaign support from Google, he is their biggest defender.
But today, as he presides as chairman of the Senate antitrust panel, Lee’s stance couldn’t be more different. With critics on both sides of the political aisle assailing big tech, Lee has questioned the need for congressional antitrust investigations, complained about big fines imposed on Google, and defended the tech industry against Republican charges of liberal bias.

Cool image time! In my never-ending review of new images downloaded each month from the high resolution camera of Mars Reconnaissance Orbiter (MRO), I came upon an image dubbed merely “Terrain Sample” in the August release. To the right, cropped and rotated to post here, is the weird terrain from that image, with the section in the white box shown below at full resolution.
To keep MRO functioning properly, they need to take images on a regular basis, even if they have no planned features coming into view. As noted by Singleton Thibodeaux-Yost, the HiRISE Targeting Specialist at the University of Arizona who requested this image,
It was not taken in response to a suggestion from the public or our team database. This image was a ride-along with another instrument on MRO. [The scientists for that other instrument] targeted this region for a particular reason and we just turned on our camera as well to gather more data while they collected their data. I title these types of images “terrain sample” as we don’t always know what the results will be.
In other words, the scientists running the high resolution camera have no inkling what they will see until see it.
This image shows the inside rim of a crater, with the crater rim to the south just beyond the image’s bottom edge. This somewhat large crater is located in the middle of Arabia Terra, one of the largest regions of the transition zone between the southern highlands and the northern lowlands (where some scientists believe an intermittent ocean might have once existed). This transition zone has many features that suggest a tidal basin on the edge of that ocean.
A few months ago I would have been entirely baffled by what we see here. I might have speculated that these strange features were another variation of that shoreline region. Maybe these features are the erosion one sees on a dried lakebed after the water has drained away.
I might have also speculated that these shapes looked like the kind of frozen ice blocks one sees in the icecap of the Arctic here on Earth.
Both speculations then would have been complete guesses.
I now know, based on things I have recently learned in writing about several other images from MRO, that the second guess is likely right (though of course my opinion as a very amateur planetary geologist should not be taken very seriously). My reasons?

ULA wins private lunar launch contract
Capitalism in space: Astrobotic, the private company building a lunar lander for NASA, has chosen ULA’s Vulcan rocket for its launch vehicle.
Astrobotic announced today that it selected United Launch Alliance’s (ULA) Vulcan Centaur rocket in a competitive commercial procurement to launch its Peregrine lunar lander to the Moon in 2021.
“We are so excited to sign with ULA and fly Peregrine on Vulcan Centaur. This contract with ULA was the result of a highly competitive commercial process, and we are grateful to everyone involved in helping us make low-cost lunar transportation possible. When we launch the first lunar lander from American soil since Apollo, onboard the first Vulcan Centaur rocket, it will be a historic day for the country and commercial enterprise,” said Astrobotic CEO, John Thornton.
This is the second contract announcement for ULA’s Vulcan rocket, with the first being Sierra Nevada’s announcement that it would use Vulcan for Dream Chaser’s first six flights.
Isn’t competition wonderful? It appears to me that ULA must be offering very cut-rate deals to get these contracts, since the rocket has not yet flown while SpaceX’s already operational Falcon Heavy (with three successful launches) could easily do the job and is a very inexpensive rocket to fly. These lower prices, instigated by competition and freedom, will mean that funding missions to the Moon will continue to become more likely, even if NASA and the federal government fail to get their act together.

Chandrayaan-2 successfully enters lunar orbit
The head of ISRO today announced that, after completed a 29 minute engine burn, India’s Chandrayaan-2 orbiter/lander/rover has successfully entered the correct orbit around the Moon.
In his briefing, Dr. Sivan announced that “The LOI maneuver was performed successfully today morning using the onboard propulsion system for a firing duration of about 29 minutes. This maneuver precisely injected Chandrayaan-2 into an orbit around the Moon.” He emphasised the unique requirement of 90 degree orbital inclination of Chandrayaan-2 and said that it was achieved by the precise execution of both the Trans Lunar Injection (performed on August 14, 2019) and today’s LOI maneuver.
“The satellite is currently located in a lunar orbit with a distance of about 114 km at perilune (nearest point to the Moon) and 18,072 km at apolune (farthest point to the Moon)”, he added.
Over the next four lunar orbits they will execute four more engine burns to lower the spacecraft to the orbit needed to send the lander/rover to the surface on September 7 in the south polar region of the Moon between the craters Manzinus C and Simpelius N at about 71 degrees latitude.

Facebook allows flat-Earthers to censor a space history book
A photographer trying to raise money for a self-published book of historical space artifacts had his Facebook ads repeatedly removed by Facebook because flat-Earthers and Moon hoax conspiracy theorists were offended.
About 24 hours after the ads were approved, he got a notification telling him the ad had been removed. He resubmitted it. It was accepted — and then removed again — 15 or 20 times, he said. The explanation given: He had run “misleading ads that resulted in high negative feedback.”
He understood that it was Facebook’s algorithm that rejected the ads, not a person. Getting additional answers proved difficult, a common complaint with advertising on Facebook. The best clues he could find came in the comments under the ads, which he and his colleagues captured in screenshots before they were removed and in responses to other posts about the project: There were phrases such as “The original moon landing was faking” and “It’s all a show,” along with memes mocking space technology. Some comments were hard to gauge, with users insisting that the earth was flat but that they’d buy the book anyway.
To fix the problem he had to hire an outside expert who knew how to get to a human being at Facebook, proving once again that Facebook is a very unethical and corrupt company. It should not have been so hard for Redgrove to get his problem fixed.
Update: In related news, Facebook has pulled a Trump campaign ad for a lot of vague reasons that really can be summed up as “We didn’t like it!”

John Arthur Martinez – The Armadillo Song
Obama’s legacy of hate
Of all of Obama’s achievements, probably the one that is going to ring down the decades the longest and maybe do the most to destroy the United States and western civilization was his willingness to either endorse or refuse to condemn the use of slanders and lies to advance the political power of his Democratic Party and the left.
The most obvious example of this were the false accusations by top Democrats that the Tea Party protesters against Obamacare were “racist”, despite zero evidence. (I speak from personal experience, as I was involved in Tea Party groups in both the DC and Tucson areas.) Obama was in a position to tamp down this hateful and dishonest rhetoric. Instead, he allowed members of his administration to encourage it.
This political tactic has now become pervasive and dominant throughout the Democratic Party and its minions in the mainstream press. This fact became especially evident to me this past weekend, during a demonstration in Portland by a group called the Proud Boys. This group was formed in 2016 in reaction to the modern political leftist pressure forcing Americans to adhere to leftist dogma. From their own webpage:
The basic tenet of the group is that we are “Western chauvinists who refuse to apologize for creating the modern world.” Like Archie Bunker, we long for the days when “girls were girls and men were men.” This wasn’t controversial even twenty years ago, but being proud of Western culture today is like being a crippled, black, lesbian communist in 1953.
…The Proud Boys confuse the media because the group is anti-SJW without being alt-right. “Western chauvinist” includes all races, religions, and sexual preferences.
I have reviewed their webpages, their videos, statements from their leaders, and can find nothing that suggests they have any links to fascism or white supremacy. Go to their webpage yourself and do the same. If anything, the actual evidence is that this group opposes such things, vehemently.
And yes, I am sure you could find bigots among them, as you can find bigots everywhere. The fundamental principles and goals of the organization however have nothing to do with bigotry. They merely wish to reassert the nobility of western civilization, an idea that all Americans should feel no shame asserting.
This past weekend, during their demonstration, they came with no masks, a lot of American flags, a lot of Trump “Make America Great Again” hats and t-shirts, and the ability to defend themselves if attacked. (The link takes you to a Daily Mail report, with lots of pictures that confirm my description but with text that generally describes the event poorly.)
It appears, from the information at this link, that the Proud Boys finished their morning demonstration after about 90 minutes — with no violence — and then went to have a barbeque.

Democrat fundraiser includes mock assassination of Donald Trump
Democrat civility: An August 16th fundraising event for Chicago Democratic state senator Martin Sandoval included a mock assassination of Donald Trump.
Meanwhile, the leftist press and Democrats accuse Trump of out-of-control rhetoric? Nothing he has ever said, no matter how crude or insulting, has ever come close to this. Nor is this the only example. Democrats, and the leftist allies in the press and in Antifa (the Democrats’ SS division), routinely use slander and hateful language, often backed up by violence against innocent citizens, to squelch any opposition. If anyone is inspiring mass murders and violence it is them, not Trump.
Sandoval has issued the typical rote apology, which has as much value as a tissue that someone has used to blow their nose. You can bet he was quite in favor of this performance at his fundraiser, and in fact approved it heartily.

Data suggests Earth-sized exoplanet has no atmosphere and resembles Mercury
Using archive data from the Spitze Space Telescope astronomers believe that an Earth-sized exoplanet about 49 light years away probably has no atmosphere and is likely similar to Mercury.
Discovered in 2018 by NASA’s Transiting Exoplanet Satellite Survey (TESS) mission, planet LHS 3844b is located 48.6 light-years from Earth and has a radius 1.3 times that of Earth. It orbits a small, cool type of star called an M dwarf – especially noteworthy because, as the most common and long-lived type of star in the Milky Way galaxy, M dwarfs may host a high percentage of the total number of planets in the galaxy.
…The Spitzer observations rule out an atmosphere with more than 10 times the pressure of Earth’s. (Measured in units called bars, Earth’s atmospheric pressure at sea level is about 1 bar.) An atmosphere between 1 and 10 bars on LHS 3844b has been almost entirely ruled out as well, although the authors note there’s a slim chance it could exist if the stellar and planetary properties were to meet some very specific and unlikely criteria. They also argue that with the planet so close to a star, a thin atmosphere would be stripped away by the star’s intense radiation and outflow of material (often called stellar winds).
For a planet to be in the habitable zone of a M dwarf it must orbit very close to the star. This research suggests that conditions that close to the star might still preclude the possibility of life.

Second gas giant found orbiting Beta Pictoris
Astronomers today announced that they have detected another exoplanet orbiting the young star Beta Pictoris 63 light years away.
This time, the team had to analyse more than 10 years of high-resolution data, obtained with the HARPS instrument at ESO’s La Silla Observatory in Chile, in order to indirectly detect the presence of β Pictoris c. This second giant planet, which has a mass nine times that of Jupiter, completes its orbit in roughly 1,200 days, and is relatively close to its star (approximately the distance between the Sun and the asteroid belt, whereas β Pictoris b is 3.3 times more distant).
Because Beta Pictoris has a very large disk of material, astronomers have expected to find exoplanets there for decades. Only in the last two decades have their instruments improved enough to allow the detections. Moreover, because the star is young, astronomers believe it gives them a glimpse into what our solar system looked like during its early formation period.

Rocket Lab & China launch satellites
Both Rocket Lab and China today launched rockets to put satellites into orbit, though it is as yet still unclear whether the Chinese launch was successful.
Rocket Lab successfully placed four smallsats into orbit. It was the company’s eightth consecutive successful launch, continuing its perfect launch record.
More important, the company now has completed four launches in 2019. Their goal, announced early this year, was to achieve a monthly pace by summer, then ramp up to twice a month by the end of the year. So far they are not quite meeting that goal, averaging one launch every 1.5 months (March, May, June, August). Still, this record is quite impressive, considering they are a very new and very small private company that it now is beginning to match or exceed the launch pace of other nations (India) as well as well-established companies (ULA).
China’s Long March 3B launched a civilian communications satellite, but according to the story at the link, “the usual announcement of a successful separation has yet to published by Chinese State media.” For the purposes of the launch standings, I will assume at the moment that this was a successful launch, but will revise this post should we learn the satellite did not reach orbit. Update: It appears the launch was successful, but the satellite is having problems. This would mean the launch counts below.
The leaders in the 2019 launch race:
13 China
12 Russia
10 SpaceX
6 Europe (Arianespace)
4 India
4 Rocket Lab
The U.S. now leads China 18 to 13 in the national rankings.
