A bullseye on Mars

1:57 pm

Layered crater at equator

Cool image time! In researching my piece last week on the glaciers of Mars I had wanted to include a picture of a typical concentric glacier-filled crater, the most widespread glacial feature on the Martian surface, found in a band at latitudes between 30 and 60 degrees. (You can see the example I found at the link above, near the end of the article.)

To find that picture I searched the Mars Reconnaissance Orbiter (MRO) archive. Among the images I found was a captioned image taken very early in MRO’s mission showing a crater with concentric rings very similar to the concentric glacial-filled craters. The image at the right is that crater, the image reduced and cropped to post here. As described in that caption,

Want to get off gmail? A possible Behind the Black option

11:53 am

On July 3rd I put out a feeler to see if there was sufficient interest among my readers for providing a private email service through Behind the Black. As I wrote then:

I am exploring the possibility of offering email services through my server for those who want to get off of gmail and google. However, before such a service can be offered, we need to know the amount of interest there might be. The demand will effect the cost, which means I can’t even give you an idea of what we might charge.

Regardless, if you are interested in having “your.name@behindtheblack.com” as your email address, please say so in the comments. There will be no obligations, by you or me or my server, but the response however will help us decide if we can do it.

And if we can do it, and many people sign on, we will then be taking the proper free enterprise approach for combating the corrupt business practices of giants like Google. Our federal government might still act to break Google up, but I think it would be far better if the free market did the job instead.

About a dozen people expressed interest at that time. In discussing this with my server, we both agreed that this is too small a number for us to begin this service. However, we are also both quite willing to do this, if the initial number of subscribers was higher.

I am therefore posting this feeler out again. If you expressed a desire to sign up as a comment in the previous post, then there is no need to comment again. However, if you did not comment previously, and think this service will be what you want, then post a comment here saying so.

It would also help me to get an idea what you would be willing to pay per month for this service. For this information I request everyone comment, including those who commented earlier.

Europe completes 1st rollout of Ariane 6 mobile launch gantry

9:32 am

The mobile launch gantry that Europe will use for its new Ariane 6 rocket successfully completed its first rollout tests last week.

This gantry is the equivalent of NASA’s VAB building. Within this gantry they will assemble Ariane 6 vertically, then roll the gantry back for launch.

Assembling a rocket vertically I think is more costly, but it also makes it possible for the rocket to launch payloads that must be installed in this manner. Thus, Ariane 6 will have this selling point over rockets like the Falcon 9 and Falcon Heavy, which are assembled horizontally.

Private lunar landing company backs out of NASA contract

9:23 am

Capitalism in space: The commercial lunar landing company, OrbitBeyond, has told NASA that it cannot fulfill its $97 million contract, only two months after that contract was announced.

NASA announced July 29 that OrbitBeyond informed the agency that “internal corporate challenges” will prevent it from carrying out a task order that NASA awarded the company May 31 as part of its Commercial Lunar Payload Services (CLPS) program. The company asked to be released from that contract, and NASA agreed.

NASA didn’t elaborate on what specific issues caused OrbitBeyond to scrap its contract with NASA, and the company didn’t immediately respond to a request for comment. At the May 31 event where NASA announced the contracts, Siba Padhi, chief executive of OrbitBeyond, said the company was still in the process of closing a round of funding. The company has not subsequently announced a funding round.

Considering its receipt of a $97 million NASA contract, it would be very puzzlingly for the company to be unable to obtain further investment capital. If anything, that contract should have encouraged funding. If the lack of funding is the cause of this termination then it also suggests the company had other problems.

This leaves NASA with two private lunar lander companies. I expect NASA will look to award the contract to a third company. The company Firefly and its team of Israeli Beresheet engineers comes immediately to mind.

Chandrayaan-2 completes third orbit maneuver

9:14 am

Chandrayaan-2 has completed its third engine burn to raise the apogee of its orbit to 71K.

The next burn is set for August 2, when the spacecraft returns to its orbital low point, the perigee. As it raises its orbit each time the time between burns gets extended because the orbit gets longer. By September however the apogee will put the spacecraft in the Moon’s gravitational field of influence, and when Chandrayaan-2 reaches that apogee engineers will then fire its engines again to slow it down and enter lunar orbit.

TMT protests continue, block all astronomy research to Mauna Kea

9:08 am

The Hawaiian government continues to allow protesters against the Thirty Meter Telescope to block all access to Mauna Kea, thus also blocking researchers and maintenance crews from working on the thirteen operating telescopes already there.

Protests against construction of a giant telescope have halted work at existing observatories on the Big Island, a report said. Workers at other facilities on the dormant Mauna Kea volcano have been denied access by demonstrators opposed to the Thirty Meter Telescope, Hawaii News Now reported Sunday.

The Mauna Kea Observatories house 13 telescopes that have led to astronomical breakthroughs for more than 40 years, including the first photo of a black hole and the discovery of the first interstellar object in space.

“All we’re looking to do is to go up the road and resume what we’ve been doing for 50 years,” said scientist Doug Simons from the Canada-France-Hawaii Telescope. The two-week closure of the access road leading to the summit has resulted in the potential loss of a year’s worth of discoveries, said Simons.

The demonstrations have also affected the scientists’ interactions with family and community members. “They have these great bonds within their family and their friends, and now there’s a big rift there,” said Jessica Dempsey from the East Asian Observatory and the James Clerk Maxwell Telescope. [emphasis mine]

If my memory is correct, previous protests did not block access to the other telescopes. That they are now doing it suggests that the protesters feel empowered and are now going for their real goal, a complete shutdown of all astronomy on Mauna Kea. The highlighted text implies this. Native workers for the other telescopes appear have suddenly discovered that these protesters want to also destroy their jobs.

Russia launches communications satellite

8:52 am

Using its Soyuz rocket the Russians today launched a satellite aimed at providing communications to Russia itself.

The satellite, while apparently providing civilian communications services, was a Russian government project. It is not commercial as we would define it in the west.

The leaders in the 2019 launch race:

11 China
10 Russia
9 SpaceX
5 Europe (Arianespace)
4 India

The U.S. continues to lead China 15 to 11 in the national rankings. At the moment it also looks like Russia has a chance to top 20 launches in 2019, which would make this its best launch year since 2015. This suggests that they have finally begun to recover from the discovery in 2017 that an engine contractor was using substandard welding materials to pocket some extra cash, thus causing many launch failures.

TESS finds the first two mini-Neptune exoplanets

9:56 am

In discovering three candidate exoplanets orbiting a nearby red dwarf star, the space telescope TESS has found the first two that are sized somewhere between the rocky Earth-sized planets and the larger Neptune-sized gas giants.

The innermost planet, TOI 270 b, is likely a rocky world about 25% larger than Earth. It orbits the star every 3.4 days at a distance about 13 times closer than Mercury orbits the Sun. Based on statistical studies of known exoplanets of similar size, the science team estimates TOI 270 b has a mass around 1.9 times greater than Earth’s. Due to its proximity to the star, planet b is an oven-hot world. Its equilibrium temperature — that is, the temperature based only on energy it receives from the star, which ignores additional warming effects from a possible atmosphere — is around 490 degrees Fahrenheit (254 degrees Celsius).

The other two planets, TOI 270 c and d, are, respectively, 2.4 and 2.1 times larger than Earth and orbit the star every 5.7 and 11.4 days. Although only about half its size, both may be similar to Neptune in our solar system, with compositions dominated by gases rather than rock, and they likely weigh around 7 and 5 times Earth’s mass, respectively.

All of the planets are expected to be tidally locked to the star, which means they only rotate once every orbit and keep the same side facing the star at all times, just as the Moon does in its orbit around Earth.

Planet c and d might best be described as mini-Neptunes, a type of planet not seen in our own solar system. The researchers hope further exploration of TOI 270 may help explain how two of these mini-Neptunes formed alongside a nearly Earth-size world.

The star is only 73 light years away.

Need I say that our level of knowledge about solar system formation is tiny at this point, and that any models any theorist creates should merely be seen as scratchpad first approximations, useful only in guiding future research and not to be taken too seriously.

Japanese private smallsat rocket company launch failure

9:46 am

Capitlism in space: Interstellar Technologies, a Japanese private smallsat rocket company, experienced on July 27 its third suborbital launch failure in four attempts.

The vehicle only reached an altitude of 13 kilometers following the launch at 4:20 p.m., falling into the sea some 9 kilometers (about 5.5. miles) offshore from Taiki, Hokkaido, its test site, Interstellar Technologies said. The rocket is the same model as Momo-3, measuring about 10 meters long, 50 centimeters in diameter and weighing 1 ton.

After failed attempts in 2017 and 2018, the startup finally found success with its third launch in May, with the rocket reaching an altitude of around 113 km before falling into the Pacific Ocean.

The failure occurred when an onboard computer detected something wrong and shut the engine down.

China tests controlled flight for returning first stage

9:41 am

Chinese news sources today confirmed that during its last launch on July 26, they tested the use of grid fins (essentially copied from SpaceX’s Falcon 9) to control the return flight of the first stage of their Long March 2C rocket.

The success of the test is of great significance for improving China’s inland rocket landing safety, minimizing the inconvenience to the local people, as well as promoting the follow-up development of carrier rockets’ controllable recovery, soft landing and reuse, according to He Wei, an official with the CASC.

“The swinging grid fins were used to control the rocket debris’ direction and attitude, much like the wings of the debris,” said Cui Zhaoyun, the deputy chief designer of Long March-2C rocket. The landing site control of large and medium rockets is much more difficult than that of small rockets, he added.

For almost forty years China has allowed these first stages to crash, sometimes very close to villages and habitable areas. Now, inspired by what freedom and U.S. innovation has accomplished, they have finally begun the process of figuring out how to land these stages vertically. Since their propellants are very toxic, it is not clear however whether they will be able to reuse them should they succeed in landing them undamaged.

Golfing with boulders on the Moon

12:20 pm

Boulder tracks on the Moon
Click for full resolution image.

Cool image time! The Lunar Reconnaissance Orbiter team this week released a beautiful image of boulder tracks rolling down the inside slope of 85-mile-wided Antoniadi crater on the far side of the Moon. The image above, cropped, reduced, and annotated to post here, shows these tracks.

The most obvious track is cool because the boulder almost made, as the scientists note, “a hole-in-one.”

Running from the outcrops to the rim of the partially buried crater is a track etched by a rolling boulder bigger than a bus. Perhaps a moonquake shook it loose. The boulder bounced and rolled toward the partially buried crater, plowing a path that is still visible through the loose material of the slope. When it reached the rim of the partially erased crater, its path curved and it slowed to a stop.

…Had it rolled just 75 meters more, the boulder might have plopped neatly into a 30-meter-diameter young impact crater on the floor of the partially erased crater.

The arrows I have added indicate two more less obvious boulder tracks. If you click on the full resolution image and zoom in you can also see another series of impressions in the middle of the photograph that look like a dotted line, suggesting they were left by a boulder bouncing down the slope.

The scattered of boulders in the floor of the small crater all likely came from the top of the big crater’s rim, which I show in the wider image below.

Wider image showing entire crater slope

The box indicates the location of the image above.

While many things over the eons could caused these boulders to roll (moonquakes, erosion from the solar wind, other nearby impacts), a close look at the ground surrounding them does not show tracks emanating from most, suggesting they have been there a very long time, long enough for the surface reworking caused by the solar wind to have smoothed those tracks out.

The Moon is airless and mostly dead. The solar wind is incredibly weak. Any changes caused by it will take a lot of time. Consider the time required to smooth out those tracks. The mind boggles.

Trump gets asylum deal with Guatemala

10:50 am

After Trump threatened Guatemala with tariffs earlier this week, that government suddenly decided yesterday to agree to an asylum deal it had previously rejected.

After President Trump invited the media into the oval office, he announced Guatemala was signing a “safe third country” asylum agreement with the United Stated. Effectively blocking Central American asylum seekers from reaching the United States and filing asylum applications. [As an outcome of the agreement asylum seekers who travel through Guatemala can no longer seek U.S. asylum.]

This agreement combined with recent Mexican efforts, also agreed to after a Trump threat of high tariffs, probably means there will be a significant reduction in illegal immigration. For certain the caravans from two years ago will cease.

As always, this does not mean the U.S., Trump, or his supporters do not welcome immigrants. What is demanded is that they follow the law.

Judge dismisses Sandmann libel case against Washington Post

10:44 am

But of course! A Kentucky judge has thrown out the $250 million Nick Sandmann libel case against the Washington Post, saying the Post was merely exercising its first amendment rights.

Everyone should understand how this works. Leftist and liberal news outlets, as well as leftist and liberal politicians and pundits, are allowed to slander and libel and lie about any conservative because of free speech. Should a conservative do it however be prepared to have the full force of the law come down on you like a brick.

More and more it appears the law is no longer for everyone. Instead, it has become a weapon by the left to oppress its opponents.

NASA to do full engine test of SLS first stage

8:08 am

NASA confirmed yesterday that it will do a full engine test of its SLS first stage, what it calls the Green Run test.

This decision makes sense. SpaceX for example routinely does a static fire test of its first stages before every flight. NASA however had hesitated doing this test because it will likely force a delay in the first launch of SLS. Unlike a commercial company like SpaceX, NASA is incapable of doing this test and then proceeding to flight quickly, mostly because the size of SLS (it is very large) and its design (very cumbersome) makes such quick action difficult.

This decision however means that it is almost certain that SLS’s first unmanned test launch cannot happen in 2020. For NASA to make Trump’s commitment to fly a lunar landing by 2024 means that NASA must compress SLS’s schedule to one flight per year. First the unmanned test flight would occur, probably in 2021. Then the first manned test flight around the Moon would follow, in 2022 or 2023. Finally the landing mission would take place in 2024.

Can NASA do this? I have many doubts. The agency’s biggest obstacle would be getting their lunar lander built in time, which by the way is not yet even designed. This isn’t the only problem. NASA for years has said that they will need from one to three years between SLS flights. This schedule demands more from them.

Meanwhile, there is a good possibility that SpaceX will beat them to the Moon. If that happens, then expect SLS to die, either before or after its first or second flight.

Starhopper has hopped

7:29 am

Capitalism in space: SpaceX last night successfully completed the first untethered flight of its Starship/Super Heavy prototype dubbed Starhopper.

This hop attempted and flew about 65 feet. They hope to do next flight, planned to be about ten times higher, in a week or two, according to a Musk tweet.

Below the fold is video of the hop. You can’t see much as the viewing angle is ground level, it is night, and the engine flames obscure things. Expect better footage from future hops.

TESS completes survey of southern hemisphere

6:36 pm

The space telescope TESS has completed its first year in orbit, surveying the entire southern hemisphere for transient events.

NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered 21 planets outside our solar system and captured data on other interesting events occurring in the southern sky during its first year of science. TESS has now turned its attention to the Northern Hemisphere to complete the most comprehensive planet-hunting expedition ever undertaken.

TESS began hunting for exoplanets (or worlds orbiting distant stars) in the southern sky in July of 2018, while also collecting data on supernovae, black holes and other phenomena in its line of sight. Along with the planets TESS has discovered, the mission has identified over 850 candidate exoplanets that are waiting for confirmation by ground-based telescopes.

It is important to emphasize that these are candidate exoplanets. They still need to be confirmed by other observations.

University punishes professor for uncovering academic fraud and incompetence

10:17 am

Portland State University (located in that hotbed of antifa fascist violence) has announced that it is punishing one of its professors for uncovering academic fraud and incompetence by co-writing several fake science papers and getting them published.

Peter Boghossian made headlines in 2018 after he and two other researchers set out to prove a point about the integrity of “peer-reviewed” academic publications by submitting several fake studies including an analysis of “dog rape culture,” and a piece that was simply a section of Hitler’s Mein Kampf reworked to include a smattering of academic buzzwords. After seven of the team’s fake submissions were accepted and published by esteemed academic journals, a Campus Reform investigation led the publisher of the infamous Portland “dog park rape culture” article to question the origins of the submission. This ultimately revealed the article as part of a larger effort by Boghossian and his team to demonstrate the inadequacies of these publications.

After his experiment, Portland State threatened Boghossian with disciplinary action, accusing him of conducting research misconduct. The school asserted that Boghossian had unethically conducted research on human subjects with his experiment. According to the school’s Institutional Review Board, Boghossian would have needed to obtain “informed consent” from the individuals reviewing his hoax articles in order for his actions to have been considered ethical.

The IRB conducted several reviews of Boghossian’s work involving his treatment of animal subjects, human subjects, and the possibility of “plagiarism, fabrication, and falsification.” On July 17, the university sent Boghossian a letter informing him that he is now barred from conducting any “human subjects related research,” as well as any university-sponsored research. Boghossian is prohibited from conducting research until he “can show satisfactory evidence of understanding of the protections afforded human subjects,” by completing a “protection of human subjects” training course and subsequently meeting with the Assistant Vice President for Research Administration to “assure [his] understanding.”

The letter, sent from Vice President for Research and Graduate Studies Mark McLellan, also warns Boghossian that the university president, as well as his department chair, dean, and provost, will be advised as to his “lack of academic integrity” and “questionable ethical behavior.”

This story is closely related to the Oberlin story below. Both universities are typical modern leftist madhouses, dominated by fake and politically driven academics who will brook no dissent. They are also increasingly bigoted against ordinary white Americans, merely because they are white. Boghossian and his cohorts did the academic community a service by identifying journals where bad research was being routinely published. His university immediately moved to squelch his effort by punishing him.

Is this the kind of place you want to send your kids? Is this the kind of place you’d want to attend, if you were a high school student?

Judge: Oberlin must post $36 million bond to appeal

9:52 am

The judge in the Gibson’s Bakery vs Oberlin College case has ruled that if Oberlin wants to appeal the judgement against it, it must first post the entire judgement amount, $36.3 million, in a bond.

According to the judge:

The need for such bond is made clear by the College’s own statements about its dire fmancial straits. If the College is to be believed, there is serious concern about its ability to pay this sizeable judgment three years from now. At trial, and in its recent filing, the College represented that there was only $59.1 million of unrestricted endowment funds available to pay any dollar judgment and that $10 million of those funds had already been committed to pay down the College’s existing debt. [Trial Tr., June 12, 2019 at 95:13-21] There remains $190 million of existing debt on the College’s books. [Id.] The College has also testified that it has a significant operating deficit and that its deficit situation is not sustainable…. [Trial Tr., June 12, 2019 atpp. 86:1-6, 88:1-9]

The College also testified at trial that they have experienced a “significant” and “steady” decline of enrollment from 2014 to 2018. [emphasis mine]

The college has seven days to post the bond, or the appeal with be squashed.

It has been very clear since the jury’s decision that Oberlin still intends to fight, and is likely to use every means in its possession, including political action, to either get the judgement dismissed, or likely make it impossible for it to pay. The judge here is telling them that they surely have the right to fight, but not at the expense of Gibson’s Bakery.

The highlighted text could be the poster child for self-unawareness. Oberlin is very aware that its enrollment is dropping, but it is entirely clueless as to why. Maybe the college should consider its own actions as the cause?

Nah. It must be those racist, homophobic, and deplorable whites! Yeah! They are the ones to blame! They’re all ignorant white supremacists! All of them!

This is essentially what the Oberlin administration has been saying during this whole debacle, as well as several years earlier. And it is essentially why students are less willing to enroll. You go to college to learn how to be a discerning educated person, not an anti-white bigot.

The state of water on the Moon

8:31 am

Link here. The article describes new research that suggests the ice thought to exist in the Moon’s permanently shadowed polar craters is constantly being reworked, with some being leached away as other processes (comets, solar wind) replenish the losses.

They also theorize that this process might be making it easier to reach that water.

For forthcoming science and exploration, the scattering of water particles could be great news. It means astronauts may need not to subject themselves and their instruments to the harsh environment of shadowed crater floors in order to find water-rich soil — they could just find it in sunny regions nearby. “This research is telling us that meteoroids are doing some of the work for us and transporting material from the coldest places to some of the boundary regions where astronauts can access it with a solar-powered rover,” Hurley said.

To put it mildly, there is a lot of uncertainty about this last conclusion.

Chandayaan-2 completes first orbit burn

8:18 am

India’s lunar orbiter/lander/rover Chandrayaan-2 yesterday completed its first orbital engine burn, raising its apogee, the high point in its orbit, 6,000 kilometers to about 51,000.

This boost meant that Isro scientists have to perform one less manoeuvre in the Earth orbit than what was planned earlier. According to the path chalked out for Chandrayaan-2 before the launch, the on-board propulsion systems were to be fired six times in Earth orbit – five times to raise the apogee and once to raise the perigee. Now, only four more “burns”, or firing of the propulsion system, will be needed on July 26 and 29, and August 2 and 6, to reach the final orbit of 233.2 x 143,953km.

…With a final boost on On August 14, Chandrayaan-2 will escape Earth’s orbit and begin its seven-day journey towards the moon. The spacecraft is scheduled to reach the moon orbit on August 20.

Once in lunar orbit they plan four more burns to lower the spacecraft to a 100 kilometer circular orbit, where the lander/rover will release and begin their own lowering process aimed for a September 7 landing.

End coming for twin Van Allen spacecraft

8:07 am

Engineers at the Applied Physics Lab in Maryland on July 19 turned off one of the two Van Allen probes, with the second probe expected to receive a similar command later this year.

As expected, following final de-orbit maneuvers in February of this year, the spacecraft has used its remaining propellant to keep its solar panels pointed at the Sun and is now out of fuel. Since it depends on the Sun to provide power to the instruments, and can no longer orient itself to acquire power, the spacecraft has been turned off. The spacecraft is in a stable, circular orbit around Earth and, in about 15 years, will re-enter the atmosphere and burn up safely. The de-orbit maneuvers in February were designed to ensure this would happen and prevent the spacecraft from becoming “space junk” in orbit.

The other Van Allen Probes spacecraft, spacecraft A, is expected to operate normally until early September.

Both spacecraft functioned five years longer than expected, and during that time discovered that there are three Van Allen belts, not two as previously thought.

China smallsat company succeeds in orbital launch

7:58 am

A Chinese semi-private company, iSpace, successfully launched two smallsats into orbit today.

iSpace’s Hyperbola-1 rocket blasted off from the Jiuquan Satellite Launch Centre at 1 p.m. (0500 GMT) Thursday, sending two satellites and payloads into a predetermined orbit, the company said in a statement on its official Wechat account.

The successful orbital launch was preceded by two failures since late last year by other startups.

More here.

I am very reluctant to call this company, along with the other Chinese smallsat companies OneSpace and LandSpace, a private commercial firm. While it might get investment capital within China, it is very clearly supervised closely by the government. Moreover, its use of solid rocket motors, as noted in the second link, strongly suggests it is taking advantage of Chinese military technology, something that could only happen under government control. From the second link:

It’s unclear how much it cost for iSpace to build the rocket. Chinese state-owned automaker Changan’s passenger car brand Oushang said it would sponsor the launch, but didn’t specify the amount. In OneSpace’s case, the firm’s nine-meter-tall, solid-propellent rocket cost the company $78 million to design, build, and launch. iSpace’s main private backers (link in Chinese) include domestic private-equity firms CDH Investments and Matrix Partners.

iSpace didn’t immediately respond to requests for comment.

But private space companies are also getting state support in China. All of the private launches so far, for example, have taken place at Jiuquan—Elon Musk’s SpaceX recently launched a rocket at NASA’s Kennedy Space Center, while its main customer is the US Air Force. What’s different in China is the constraints that come with having state backing. In June, China rolled out a set of rules that restrict what private companies can develop and manufacture. It’s unclear if that may restrict private companies’ capabilities in building larger rockets that could rival state rocket builders. [emphasis mine]

The money for this comes from state-owned companies. The technology comes from military hardware. The goals are almost all military in nature. I would also bet, because of the lack of information released, that the satellites launched today were military payloads. This is hardly an independent private company competing on the open market.

Nonetheless, this success gives China a new capability and raises its status as a world space power.

The leaders in the 2019 launch race:

10 China
9 Russia
8 SpaceX
5 Europe (Arianespace)
4 India

The U.S. still leads China 14 to 10 in the national rankings.

Starhopper’s 1st test hop aborts

11:40 pm

Capitalism in space: SpaceX’s first attempt to fly Starhopper untethered in a short vertical flight was aborted only a few seconds after engine ignition.

Video of the test is below the fold. The vehicle never leaves the ground, and there are flames visible near its top, something one should not see. Obviously this is a development program, so failures like this are to be expected. More significant is the speed in which the company is moving. It is only a week since their last StarHopper test, which also had issues. Rather than take years to move forward (like NASA), they are pushing forward aggressively.

Mueller’s testimony today proves witch hunt failed

6:43 pm

There have been numerous stories today in all the press, both left and right, about Robert Mueller’s testimony today in Congress, mostly concluding that Mueller came off very badly, thereby bursting the balloon of the continuing empty and largely disproved accusations by the Democrats that Trump colluded with Russia during the 2016 election. If anything Mueller proved by his stumbling answers plus his refusal to answer more than 150 questions that his effort was at best incompetent, and at worst a partisan witch hunt.

This conclusion is not a surprise however to anyone who has paid even the slightest close attention Mueller’s work, both now and in the past.

However, the short clip below the fold, taken from Mueller’s testimony today, best represents how corrupt and incompetent Mueller really is. It took place during questioning by a friendly Democratic congressman as he was attempting to demonstrate how honorable and fair-minded Mueller is. Instead, it proved why almost everything attempted by our so-called elites in Washington fails. They don’t have to be corrupt because they are also incompetent.

The clip comes from a story at PJ Media. For Mueller and the Democrats, it is embarrassing. For Trump and the Republicans it is laughable. For the American people it is distressing, because we all know that Mueller is very stereotypical of most of those running Washington.

Possibility of meteorites from bright fireball in Ontario

1:54 pm

Astronomers were successfully able to track and photograph a bright fireball over Canada early today, and think it is strongly possible that pieces of it might have hit the ground.

Preliminary results indicate that the fireball first became visible just south of Oshawa over Lake Ontario at an altitude of 93 km. It traveled over Clarington and passed just west of Peterborough before extinguishing just west of Bancroft. The fireball rivaled the full moon in brightness and had a number of bright flares near the end of its flight. The meteoroid was roughly the size of a small beachball (approx. 30cm in diameter) and likely dropped a small number of meteorite fragments in the tens to hundreds of grams size-range on the ground.

Brown and his collaborators at Western and the Royal Ontario Museum are interested in connecting with people from the area of the potential fall, who may have heard anything unusual, or who may have found possible meteorites.

…Meteorites can be recognized by their dark, often scalloped exterior. Usually they will be denser than a ‘normal’ rock and will often be attracted to a magnet due to their metal content. Meteorites are not dangerous, but if recovered, it is best to place them in a clean plastic bag or wrap them in aluminum foil. They should also be handled as little as possible to help preserve their scientific value. In Canada, meteorites belong to the owner of the land upon which they are found. If individuals plan to search, they should always obtain permission of the land-owner before venturing onto private land.

If you live up in that neck of the woods, take a look around. You might find something.
