Original investors sue Firefly
Capitalism in space: The original investors in Firefly Aerospace, cut out when the company went bankrupt, have filed suit against the reborn company.
A group of original shareholders in the defunct Firefly Space Systems have accused co-founder and CEO Tom Markusic of fraudulently conspiring with Ukrainian billionaire Maxym Polyakov to force the rocket company into bankruptcy in 2017 and reconstitute it under a nearly identical name without giving them any stake in the new venture.
Markusic “betrayed the trust of his original co-founders and investors and committed fraud to cut them out of his aerospace company. Instead of managing the operations of the Original Firefly, a revolutionary rocket company with endless potential, Markusic schemed with…Maxym Polyakov…to rob Plaintiffs of their investments and form a new company called Firefly Aerospace, Inc. (the ‘New Firefly’),” the plaintiffs said in a lawsuit.
The article at the link has a lot more information. Read it all.
This is also not the first time Markusic has been sued. He left Virgin Galactic to found Firefly, and was then sued by Branson’s company for stealing proprietary technology. That lawsuit was settled when Markusic agreed to not use that technology in Firefly’s rockets.

Soyuz rocket launches five satellites for Arianespace
A Russian Soyuz rocket, launching from French Guiana for Arianespace, successfully placed five satellites in orbit early this morning, including CHEOPS, a European space telescope designed to study exoplanets.
Though this was a Russian rocket, I count it as an Arianespace launch as that is the company under which the launch operates. I also realize this is open to debate.
The leaders in the 2019 launch race:
30 China
20 Russia
13 SpaceX
8 Arianespace (Europe)
China still leads the U.S. 30 to 26 in the national rankings.

FISA court condemns FBI
The FISA court has issued a rare public rebuke of the FBI over its apparent misconduct and illegal tampering of evidence, as documented by the inspector general report released last week, misconduct aimed at misleading the court into issuing uncalled FISA warrants.
[T]he chief judge of the Foreign Intelligence Surveillance Court [FISC] strongly criticized the FBI over its surveillance-application process, giving the bureau until Jan. 10 to come up with solutions, in the wake of findings from Justice Department Inspector General Michael E. Horowitz.
The order, from the court’s presiding judge Rosemary M. Collyer, came just a week after the release of Horowitz’s withering report about the wiretapping of Carter Page, a former campaign adviser to President Trump. “The FBI’s handling of the Carter Page applications, as portrayed in the [Office of Inspector General] report, was antithetical to the heightened duty of candor described above,” Collyer wrote in her four-page order. “The frequency with which representations made by FBI personnel turned out to be unsupported or contradicted by information in their possession, and with which they withheld information detrimental to their case, calls into question whether information contained in other FBI applications is reliable.” [emphasis mine]
This is another independent confirmation that the behavior of the upper echelons of the FBI during the Obama administration was corrupt, apparently acting to take sides during the 2016 election against Donald Trump.
The highlighted words however are to me very distressing. The FISA court is asking the bad apples to come up with new procedures to prevent them from behaving as bad apples again. If this is all that happens then they will have gotten away with it, and will proceed to do worse in 2020 and beyond.
What needs to happen is firm contempt citations against specific individuals, people like James Comey, followed by prosecution. Until that happens the bad guys will still be in charge, and the American justice system will still be corrupted.

Martian impacts and streaks
Click for full image.
In the most recent image download from the high resolution camera on Mars Reconnaissance Orbiter (MRO), there was the cool image to the right, reduced and cropped to post here, of a crater that appeared to have hundreds and hundreds of slope streaks along its inner slopes.
Slope streaks are quite mysterious. They are found in the equatorial regions as dark (though sometimes light) streaks on steep slopes, appearing throughout the year and slowly fading over time. They also appear to be a geological phenomenon unique to Mars. Nothing on Earth or any other planet appears to correspond.
As such, their nature and cause remains unknown, though there are a bunch of theories, with the most popular being that these are a kind of dust avalanche. They are always found in connection with dust-covered terrain, but they also make no significant topological change to the surface, other than brightness.
The slope streaks in this crater are especially intriguing, because of the number of streaks. In digging further into the MRO archive I found a number of images of this crater and its surrounding terrain. It appears that sometime before 2012 there was a relatively recent impact close to the exterior of the eastern rim of this crater. The image below, taken in 2014 by MRO, shows this impact as the large dark splotch, with the new crater indicated by the arrow..

Thomas Dolby – Blinded Me With Science
Spygate from a scientific perspective
Back in February 2018, Republican-controlled committees in both the House and the Senate released detailed memos, dubbed the Nunes and Grassley memos respectively, accusing the FBI and the Obama Justice Department of using unverified and false information that was nothing more than opposition research paid for by the Clinton campaign to illegally obtain Foreign Intelligence Surveillance Act (FISA) warrants from the Foreign Intelligence Surveillance Court (FISC), warrants that allowed them to spy on the campaign of Donald Trump as well as his administration following his election victory in 2016.
Put more bluntly, the Republicans accused the Clinton campaign, with the help of the Obama administration, of weaponizing the surveillance powers of the FBI and the Justice Department in order to defeat their political opponents.
Not surprisingly, the Democrats and former Obama officials denied these allegations, calling both memos partisan and false. In the House the Democrats issued their own memo, claiming the Republican memos left out key information that made their arguments invalid.
Who was right? What was true? How was an ordinary citizen going to determine which of these competing political positions properly described what had actually happened?
At the time I admit my instincts and own personal biases led me to believe the Republicans. Even so, the allegations were so horrifying — suggesting a clear abuse of power and a willingness of people in Washington to subvert an American election — that some skepticism of the Republican accusations was certainly reasonable.
In fact, the best thing one could do in this situation is to take a scientific approach to the problem. The Republicans had put forth a theory, citing some data that suggested the Obama administration, the Justice Department, and the FBI had abused their power in the worst possible manner. To prove that theory the Republicans would require both corroborating evidence as well as independent reviews that confirmed their conclusions.

Turkey buys machine gun toting drones
Our fascist future: Turkey has purchased shipment of an unspecified number of drones equipped with a machine gun capable of firing as many as 200 rounds.
Made by the country’s own Asisguard, the Songar drone can carry 200 rounds of 5.56 x 45 mm NATO class ammo, and can hit a 15-cm-square (6-inch-square) target from 200 m (650 ft) away with single shots, 15-bullet bursts or a full auto unloading.
The 25-kg (55-lb) drones use a four-armed carbon body design with two coaxially mounted large props on each arm. The automatic machine gun beneath rests in a tilting mount, allowing a remote operator to aim it using controls that would be familiar to anyone who’s used the camera on a DJI Phantom. It carries sufficient battery and powerful enough communications to fly 10 km (6.2 mi) on a mission, it’s GPS and GLONASS stabilized, and it offers twin camera operation for a pilot and gunner if required.
This is not the first or the most sophisticated killing drone ever built. Its simplicity however suggests that it is becoming very easy for governments and the power-hungry individuals who like to run them to obtain technology capable of killing their opposition, in a way that will be untraceable.
I have embedded below the fold a sales video produced by the company. If it doesn’t send chills up your spine you are very divorced from reality.

New info on Long March 5 launch failures
An article in the English Chinese press today about the upcoming third launch of China’s Long March 5 rocket revealed some new information about the failures of that rocket during its first two test flights.
On its maiden mission in November 2016, the rocket failed to reach the speed required for the early phase of the flight; still, extra booster fuel burned in the final stage lifted its satellite cargo into orbit and allowed China to declare the trip a success.
In the second flight a few months later, though, the main engine died minutes after take-off, and the rocket plunged into the sea.
I have tried to read every iota of information released about the first two launches of the Long March 5 in order to figure out what went wrong during its second launch. At no time however had I ever come across any report that described any launch problems during its first flight. The Chinese always touted that first flight as a complete success, with no problems.
We now learn that the first stage during that first launch was under-powered, a problem that was not dealt with before the second launch, resulting in the complete failure of that second launch.
This is the typical behavior one sees in a government-run top-down program. Rather than bluntly address problems to fix them, even if it means someone will be embarrassed, management acts to protect itself, hiding problems so as to avoid blame. The result is always more failures.
As long as China’s economy is booming and providing its government with lots of cash for its space program, such problems can be papered over and even overcome. The second however that economy begins to falter, the program will stumble, the hidden problems acting like an avalanche to overwhelm everything.

Vector files for bankruptcy
Capitalism in space: On December 13 the smallsat rocket company Vector officially filed for bankruptcy, a precursor to having its assets sold off.
The company filed a voluntary petition for bankruptcy with the United States Bankruptcy Court for the District of Delaware, the state where the company was incorporated.
…Vector had been one of the leading companies in the small launch vehicle market until August, when the company said that a “significant change in financing” led it to pause operations and lay off nearly all of its more than 150 employees. Jim Cantrell, Vector’s chief executive, also left the company at the time. That announcement came just two days after the company won an Air Force launch contract.
According to industry sources familiar with the company, the August layoffs were triggered when one of the company’s major investors, venture fund Sequoia, withdrew its support for the company because of concerns about how the company was managed. That came as Vector was working on a new funding round, and Sequoia’s decision had a domino effect, causing other investors to back out. Sequoia didn’t respond to a request for comment in August about any role it played in Vector’s problems.
The company is currently being funded through “debtor in possession” financing from Lockheed Martin, according to a resolution by Vector’s board of directors included in the filing. Under a Nov. 20 agreement, Lockheed provided Vector with a $500,000 secured loan and proposed purchasing Vector’s assets associated with a satellite program called GalacticSky for no more than $2.5 million.
While companies sometimes recover from this situation, in this case Vector looks quite dead, for good. A real tragedy, but part of the reality of capitalism. The competition fuels innovation and success, but carries great risk and the real possibility of failure.

Josh & Larkin – Just Like Heaven
North magnetic pole continues its drift
The uncertainty of science: The newest 2020 version of the World Magnetic Model, released on December 10, 2019, shows that the north magnetic pole is continuing its unprecedented drift eastward and away from the Canadian Arctic.
A new and updated version of the WMM is released every five years. The latest WMM2020 model will extend to 2025.
Since Earth’s magnetic field is created by its moving, molten iron core, its poles aren’t stationary and they wander independently of each other. Since its first formal discovery in 1831, the north magnetic pole has traveled around 1,400 miles (2,250 km). This wandering has been generally quite slow, allowing scientists to keep track of its position fairly easily. Since the turn of the century, this speed has increased.
The WMM2020 forecasts that the northern magnetic pole will continue drifting toward Russia, although at a slowly decreasing speed—down to about 40 km per year compared to the average speed of 55 km over the past twenty years.
Though we know the magnetic field is produced by the magnetism related to the Earth’s molten iron core, scientists do not have a solid understanding of the details, including why the drift of the pole has accelerated this century as well as shifted eastward.

The importance of small telescopes to science and civilization
Largest cluster of telescopes on Mount Lemmon, six visible with three just out of view.
On December 11, 2019 I was kindly given a personal tour by Alan Strauss, director of the Mount Lemmon Sky Center, of the telescopes located on the mountaintops of the Santa Catalina Mountains overlooking Tucson. Strauss runs the educational outreach program for the University of Arizona astronomy department and the Steward Observatory, both of which operate the mountaintop facility.
The telescopes, numbering almost a dozen, are in two groups, two telescopes on the peak of Mount Bigelow and the rest clustered on the higher peak of Mount Lemmon. None are very gigantic by today’s standards, with their primary mirrors ranging in size from 20- to 61-inches. For comparison, the largest operating telescope in the world on the Canary Islands is 409 inches across. Hubble has a 94-inch mirror. And the new giant telescopes under design or being built have mirrors ranging from 842 inches (Giant Magellan) to 1,654 inches (European Extremely Large Telescope).
Thus, the small telescopes in the Santa Catalinas generally don’t make the news. They are considered passe and out-of-date, not capable of doing the kind of cutting edge astronomy that all the coolest astronomers hunger for.
Yet, without them, we likely would not have future astronomers. » Read more
Scientists reject discovery of biggest known black hole
The uncertainty of science: In three new papers published this week astronomers have found that the announced discovery in early December of the biggest super-massive black hole ever found, 70 times the mass of the Sun, does not hold up.
In a recent study (a peer-reviewed study published Nov. 27), a team of scientists reported the discovery of the binary system LB-1, which contains a star and, according to the findings, a black hole companion 70 times the mass of our sun. This was major news, a stellar-mass black holes (black holes formed by the gravitational collapse of a star) are typically less than half that massive. But while the study, led by Jifeng Liu, of the National Astronomical Observatory of China (NAOC) of the Chinese Academy of Sciences, was exciting, it was also wrong.
Three new papers came out this week that reexamined the findings from Liu’s study, and these studies say that LB-1’s black hole isn’t actually all that massive.
The new papers find that a closer look at the data finds that it wasn’t doing what the initial researchers thought.

Maven makes first map of Mars’ high altitude winds
Scientists using the Martian orbiter Maven have produced the first global map of the high altitude wind circulation of Mars.
The measurements of winds that were recently mapped above Mars were found at an altitude range of about 140-240 kilometers (85-150 miles) above the planet’s surface.
The wind data has been gathered by the Neutral Gas and Ion Mass Spectrometer (NGIMS). NGIMS’ original purpose was to determine the structure and composition of the Martian atmosphere by measuring in it the amounts of ions (electrically charged particles) and gases. However, although it was not originally designed to do so, in April 2016, the MAVEN team began using NGIMS to observe horizontal winds. Pausing normal collection of data, scientists on Earth programmed the instrument to nod back and forth so that it could detect the direction of winds along its track.
By combining data from many tracks as MAVEN orbits Mars, scientists slowly built up a map of wind behavior. This led to a startling discovery: the wind patterns actually correlated with the Martian topography below.
They have found that even at this high altitude the winds shift around the high volcanoes of the Tharsis Bulge.
To my eye, the wind pattern seen in the image, taken from the video at the link, is remarkably similar to the global wind patterns found on Venus, forming a widening V-pattern moving from east to west. Though the two are vastly different, the similarity is quite intriguing.

Rocket Lab opens Wallops Island launchpad
Capitalism in space: Rocket Lab yesterday officially cut the ribbon on its first U.S.-based launchpad at Wallops Island, Virginia.
Rocket Lab aims to launch up to 12 missions a year from LC-2 [Wallops], about one a month, once flights begin in 2020. The first mission will launch in spring 2020 to deliver the U.S. Air Force’s Space Test Program 27RM (STP-27RM) mission into orbit. That mission will launch a microsatellite called Monolith to see if small satellites can effectively carry “large aperture” space weather payloads, said Lt. Col. Meagan Thrush, program element monitor for space launch and control for the Air Force, in a news conference here today.
The company has a similar launch rate capability at its New Zealand launch site. Thus, if they have the customers, Rocket Lab now has the ability to launch upwards of 24 times next year.

Rocket Lab aims to launch up to 12 missions a year from LC-2 [Wallops], about one a month, once flights begin in 2020. The first mission will launch in spring 2020 to deliver the U.S. Air Force’s Space Test Program 27RM (STP-27RM) mission into orbit. That mission will launch a microsatellite called Monolith to see if small satellites can effectively carry “large aperture” space weather payloads, said Lt. Col. Meagan Thrush, program element monitor for space launch and control for the Air Force, in a news conference here today.

Interacting galaxies
Click for full image.
Astronomers using the 8-meter Gemini Telescope on Mauna Kea today released a new image of the Heron galaxy, showing its interaction with a nearby neighbor.
The new image captures the slow and intimate dance of a pair of galaxies some 160 million light-years distant and reveals the sparkle of subsequent star formation fueled by the pair’s interactions.
The two galaxies, astronomers have concluded, have already “collided” at least once. However, galactic collisions can be a lengthy process of successive gravitational encounters, which over time can morph the galaxies into exotic, yet unrecognizable forms. These galaxies, as in all galactic collisions, are engaged in a ghostly dance as the distances between the stars in each galaxy preclude actual stellar collisions and their overall shapes are deformed only by each galaxy’s gravity.
One byproduct of the turbulence caused by the interaction is the coalescence of hydrogen gas into regions of star formation. In this image, these stellar nurseries are revealed in the form of the reddish clumps scattered in a ring-like fashion in the larger galaxy (and a few in the smaller galaxy). Also visible is a dusty ring that is seen in silhouette against the backdrop of the larger galaxy. A similar ring structure is seen in this previous image from the Gemini Observatory, likely the result of another interacting galactic pair.

New storm spotted at Jupiter’s south pole
Click for full image.
New images from Juno have revealed the formation of a new Texas-sized cyclone joining the circle of storms around Jupiter’s south pole.
In the infrared Juno image to the right, the new storm is the small bright cyclone in the lower right.
[D]uring Juno’s 22nd science pass [on November 3], a new, smaller cyclone churned to life and joined the fray. “Data from Juno’s Jovian Infrared Auroral Mapper [JIRAM] instrument indicates we went from a pentagon of cyclones surrounding one at the center to a hexagonal arrangement,” said Alessandro Mura, a Juno co-investigator at the National Institute for Astrophysics in Rome. “This new addition is smaller in stature than its six more established cyclonic brothers: It’s about the size of Texas. Maybe JIRAM data from future flybys will show the cyclone growing to the same size as its neighbors.”
Probing the weather layer down to 30 to 45 miles (50 to 70 kilometers) below Jupiter’s cloud tops, JIRAM captures infrared light emerging from deep inside Jupiter. Its data indicate wind speeds of the new cyclone average 225 mph (362 kph) – comparable to the velocity found in its six more established polar colleagues.
Because of Juno’s orbit we do not get continuous views of the gas giant’s cloud-tops, so we can’t see the moment-by-moment evolution of these storms, which makes it impossible to obtain a full understanding of their formation or disappearance. Even then it will likely take centuries of observations to even begin to get a fuller understanding of the meteorology of Jupiter.

Major victory for Boris Johnson, Tories, and Brexit
A victory for democracy: In the elections today in the United Kingdom it appears at this moment that the conservative Tories under Boris Johnson, running under a platform to quickly enforce the public’s vote three years ago to leave the European Union, have won the biggest majority since the 1980s under Margaret Thatcher.
As is typical in the modern journalist field, these results are also much more favorable to the conservatives than all the polls, which had called for a much closer result. The result is also a major rejection of Great Britain’s leftist and increasingly anti-Semitic Labor Party under Jeremy Corbyn.
Most important, the victory for Johnson is also a vindication of his strong position that he and Great Britain’s politicians had a responsibility to respect the voters’ choice three years ago to exit the European Union, and the effort by politicians to nullify that vote was a direct attack on democracy. The voters have clearly shown their contempt for that nullification effort, and have said so forcefully at the polls.
My immediate thought, from an American perspective: If only the American voters were as willing to make such a forceful statement. Our Democratic Party has been acting as bad and as anti-democratic as the politicians in the UK these past three years. It is long past time for a major political house-cleaning in Washington.
So far, the American voters have shown no inclination to do this, however, and in fact in the 2018 election did the exact opposite, rewarding the corrupt Democratic Party with more power by giving them control of the House. The result has been this ludicrous impeachment effort by the Democrats that is blatantly an effort to nullify the 2016 presidential election. They have no grounds for impeachment and the removal of Donald Trump, other than the fact that they don’t like him and that he beat them in a fair election.
They should be punished in the same way. Will the American voters do it? So far I remain pessimistic. I also pray every day that my pessimism turns out to be wrong.

New Hubble images of Comet 2I/Borisov
Click for full image.
Scientists today released new images taken by the Hubble Space Telescope of the interstellar object Comet 2I/Borisov. The image on the left was taken prior to the comet’s closest approach to the Sun, while the image on the right was taken during that closest approach. The vertical smeared object to the left in the earlier image is a galaxy that happened to be in the field of view. The blue color of both images is a false color to bring out details.
“Hubble gives us the best upper limit of the size of comet Borisov’s nucleus, which is the really important part of the comet,” said David Jewitt, a UCLA professor of planetary science and astronomy, whose team has captured the best and sharpest look at this first confirmed interstellar comet. “Surprisingly, our Hubble images show that its nucleus is more than 15 times smaller than earlier investigations suggested it might be. Our Hubble images show that the radius is smaller than half-a-kilometer. Knowing the size is potentially useful for beginning to estimate how common such objects may be in the solar system and our galaxy. Borisov is the first known interstellar comet, and we would like to learn how many others there are.”
The first image was taken from a distance of 203 million miles, while the second was taken from 185 million miles. Expect more images in late December, when the comet makes its closest approach to Earth at a distance of 180 million miles.

OSIRIS-REx team picks primary sample site
Click for full image.
The OSIRIS-REx science team has picked the site they have dubbed Nightingale as the primary landing site where they will attempt to obtain a sample from the asteroid Bennu in the summer of 2020. The back-up site is Osprey at the equator.
I have embedded the replay of the NASA live stream of the press event below the fold. The first 21 minutes of the video are an overview of the mission, leading up to the announcement by Dante Lauretta, OSIRIS-REx’s principal investigator. He notes then that the site “does have some hazards” but they chose it for its “scientific value.” While its higher latitude location has some advantages, it also makes it more difficult for landing. The one large boulder there, which Lauretta calls “Mt Doom,” also carries risk for the touch-and-go operations.
The back-up site, Osprey, is on the equator with less hazards, but will present more problems obtaining the tiny-sized particles the sample grab equipment was designed to get.
Not that this matters, but if I have been in a betting pool I would have won, since Nightingale has been my guess for which site they’d pick since early November.

Buyer of Stratolaunch revealed though unconfirmed
A news story today at Geekwire has revealed, based on business filings in Washington and California, the new owner of the company Stratolaunch.
Filings with regulators in California and Washington show that a new LLC business, also called Stratolaunch, was incorporated in late October, at Stratolaunch’s existing offices in Seattle and Mojave, Calif. The new Stratolaunch’s executive vice president is named as Michael Palmer, Cerberus’ managing director.
Private-equity firms typically replace existing managers as a prelude to realigning businesses they buy, which can involve firing, automation and offshoring. However, it appears that Jean Floyd, Stratolaunch’s president and CEO since 2015, remains in his roles for now.
It appears the new owners, who did not confirm the Geekwire story, are now marketing the huge Roc airplane as a launch platform for hypersonic test flights rather than orbital satellites.
