Lockheed Martin buys Aerojet Rocketdyne for $4.4 billion

December 21, 2020 10:20 am Robert Zimmerman

Capitalism in space: Lockheed Martin officials announced yesterday that it will buy the rocket engine company Aerojet Rocketdyne for $4.4 billion.

James Taiclet, Lockheed Martin’s president and CEO, said the acquisition gives the company a larger footprint in space and hypersonic technology. He said Aerojet Rocketdyne’s propulsion systems already are key components of Lockheed Martin’s supply chain across several business areas. “The proposed acquisition adds substantial expertise in propulsion to Lockheed Martin’s portfolio,” the company said in a news release.

Aerejet Rocketdyne has been in trouble because it has had problems finding customers for its engines. This acquisition will give Lockheed Martin more technical capabilities should it decide to enter the launch industry with its own rocket.

Samples from space!

December 19, 2020 9:16 am Robert Zimmerman

Scientists from both the Japanese Hayabusa-2 mission to the asteroid Ryugu and the Chinese Chang’e-5 mission to the Moon announced yesterday the total amount of material they successfully recovered.

The numbers appear to diminish the Japanese success, but that is a mistake. Getting anything back from a rubble-pile asteroid that had never been touched before and is much farther away from Earth than the Moon was a very great achievement. The 5.4 grams is also more than fifty times the minimum amount they had hoped for.

This is also not to diminish the Chinese achievement, They not only returned almost four pounds, some of that material also came from a core sample. They thus got material both from the surface and the interior of the Moon, no small feat from an unmanned robot craft.

Scientists from both nations will now begin studying their samples. Both have said that some samples will be made available to scientists from other countries, though in the case of China it will be tricky for any American scientist to partner with China in this research, since it is by federal law illegal for them to do so.

Mysterious signal detected possibly coming from Proxima Centauri

December 19, 2020 9:05 am Robert Zimmerman

The uncertainty of science: Breakthough Listen, the project funded to the tune of $100 million by billionaire Yuri Milner with the goal of listening for alien radio signals, in 2019 detected a single radio tone that appeared to be coming from the nearest star, Proxima Centauri.

A team had been using the Parkes radio telescope in Australia to study Proxima Centauri for signs of flares coming from the red dwarf star, in part to understand how such flares might affect Proxima’s planets. The system hosts at least two worlds. The first, dubbed Proxima b upon its discovery in 2016, is about 1.2 times the size of Earth and in an 11-day orbit. Proxima b resides in the star’s “habitable zone,” a hazily defined sector in which liquid water could exist upon a rocky planet’s surface—provided, that is, Proxima Centauri’s intense stellar flares have not sputtered away a world’s atmosphere. Another planet, the roughly seven-Earth-mass Proxima c, was discovered in 2019 in a frigid 5.2-year orbit.

Using Parkes, the astronomers had observed the star for 26 hours as part of their stellar-flare study, but, as is routine within the Breakthrough Listen project, they also flagged the resulting data for a later look to seek out any candidate SETI signals. The task fell to a young intern in Siemion’s SETI program at Berkeley, Shane Smith, who is also a teaching assistant at Hillsdale College in Michigan. Smith began sifting through the data in June of this year, but it was not until late October that he stumbled upon the curious narrowband emission, needle-sharp at 982.002 megahertz, hidden in plain view in the Proxima Centauri observations. From there, things happened fast—with good reason. “It’s the most exciting signal that we’ve found in the Breakthrough Listen project, because we haven’t had a signal jump through this many of our filters before,” says Sofia Sheikh from Penn State University, who helmed the subsequent analysis of the signal for Breakthrough Listen and is the lead author on an upcoming paper detailing that work, which will be published in early 2021. Soon, the team began calling the signal by a more formal name: BLC1, for “Breakthrough Listen Candidate 1.”

The data so far does not suggest this signal was produced by an alien technology. Instead, it likely is a spurious signal from some natural or human source, picked up by accident, as was the SETI “Wow” signal that for years puzzled astronomers until they traced it to a comet.

However, as they do not yet have an explanation, it is a mystery of some importance.

SpaceX completes 25th orbital launch in 2020

December 19, 2020 8:45 am Robert Zimmerman

Capitalism in space: SpaceX today successfully completed its 25th orbital launch in 2020, using its Falcon 9 rocket to put an American spy satellite into orbit.

The first stage successfully landed at Cape Canaveral, completing its fifth flight.

Not only is 25 launches in a single year a new record for SpaceX, it is also four more launches than the company predicted it would achieve in 2020.

This was also the 40th successful American orbital launch in 2020, the first time since 1968 that the U.S. has had that many launches. In 1968 the launches were almost all dictated by the government, on rockets controlled by the government. Today, the rockets are all privately designed and owned, with the small number of government launches occurring with the government merely the customer buying a product.

The leaders in the 2020 launch race:

33 China
25 SpaceX
15 Russia
6 ULA
6 Rocket Lab

The U.S. now leads China 40 to 33 in the national rankings. The rankings also should not change significantly in the last two weeks of the year, as the U.S. has no more scheduled launches and China and Russia only one.

Maricopa County election board defies state subpoenas

December 18, 2020 2:18 pm Robert Zimmerman

And they expect the public to trust them? The election board of Maricopa County has decided to defy the subpoenas issued by the state’s legislature for getting a full audit of its election results, and will instead file a lawsuit against those legislators.

It seems to me that if there was nothing wrong with the Dominion tabulators and the count, than the board would welcome this audit. That they are stonewalling it is if anything evidence that there is likely something they are hiding.

We have now reached the Rubicon. Are our elected officials truly in charge, or are they to be ordered around by unelected bureaucrats like mere serfs? If the state legislature and the governor does not act here, then they are no more than figureheads, and we are now ruled by fiat, by the bureaucracy. Arizona does not have a democracy ruled by law any longer.

Subaru Telescope photographs Hayabusa-2’s next target asteroid

December 18, 2020 2:09 pm Robert Zimmerman

In order to better constrain its orbit, the Subaru Telescope in Hawaii has obtained new photographs of Hayabusa-2’s next target asteroid, 100-foot-wide 1998 KY26.

This asteroid is predicted to approach to within 0.47 AU of Earth in mid to late December 2020, giving us a rare opportunity that comes only once every three and a half years. However, the diameter of 1998 KY26 is estimated to be no more than 30 meters, and thus its brightness is so dim that ground-based observations of the asteroid are difficult without a very large telescope.

The observations with the Subaru Telescope were conducted upon the request of the Institute for Space and Astronautical Science (ISAS), JAXA. And as a result, 1998 KY26 was photographed in the direction of the constellation Gemini as a 25.4-magnitude point of light with a measurement uncertainty of 0.7 mag. The positional data collected during these observations will be used to improve the accuracy of the orbital elements of the asteroid. Similar observations were conducted with the Very Large Telescope (VLT) of the European Southern Observatory (ESO).

If all goes right Hayabusa-2 will rendezvous with 1998 KY26 in the summer of 2031.

NASA decides to fly Orion with failed power unit

December 18, 2020 1:59 pm Robert Zimmerman

Because a repair would delay the first SLS launch for months if not a year, NASA has decided to fly Orion on that November ’21 mission with failed electronics power unit.

In a Dec. 17 statement, NASA said it had decided to “use as is” one of eight power and data units (PDU) on the Orion spacecraft, which provide communications between the spacecraft’s computers and other components. One of two redundant channels in one of two communications cards in that PDU is not working.

…NASA, in its statement about deciding not to replace the PDU, did not go into details about the repair options, but said that the risks of damaging the spacecraft during the PDU repair outweighed any loss of data should the unit completely malfunction.

Engineers, the agency stated, “determined that due to the limited accessibility to this particular box, the degree of intrusiveness to the overall spacecraft systems, and other factors, the risk of collateral damage outweighed the risk associated with the loss of one leg of redundancy in a highly redundant system.”

“NASA has confidence in the health of the overall power and data system, which has been through thousands of hours of powered operations and testing,” the agency added, noting that the PDU in question was still “fully functional.”

Let’s then assess Orion. The contract was issued to Lockheed Martin in 2006. In the fourteen years since Congress has spent about $17 billion on this manned capsule. In that time it has flown once, during a test flight that was intended to test its heat shield, even though when that flight happened NASA had already decided that it was not going to use the heat shield design it was testing.

Orion’s second flight in November ’21 will be unmanned, but it will be flying with this failed unit. The next time it is supposed to fly will be in ’24, when NASA is hoping to send astronauts on a lunar landing missions. By that time NASA will have spent about $20 billion on Orion, and gotten two test capsules (both unrepresentative of the flight model) plus one manned mission.

Would you fly on this capsule under these circumstances? I wouldn’t, especially considering the non-track record of its rocket, SLS.

As the taxpayer, do you think you’ve gotten your money’s worth from this capsule? I don’t. I think it has been an ungodly waste of money, and a demonstration of the incapability of NASA and the big space contractors Boeing and Lockheed Martin of getting anything accomplished. Depend on them, and you will never go anywhere.

Dominion CEO responds to Antrim audit in hearing

December 18, 2020 1:05 pm Robert Zimmerman

All trust is lost: John Poulos, the CEO of Dominion, the company that provided the software and tabulators used to count ballots in numerous states and which have been accused of being unreliable and subject to vote tampering, responded to those charges in a legislative hearing in Michigan.

Poulos told legislators in Michigan via video link on Dec. 15 that his company’s machines and software were not involved in any “switched or deleted votes.” He said that because of a rule change, the machine programming needed to be updated in October. But Antrim County officials failed to update all 18 tabulators, meaning some had new programming while some still had the old programming.

Officials then forgot to conduct the logic and accuracy tests on the programming, he said. A third error took place when a contracting firm in October programmed the tabulators in a way that allowed memory cards with both the old and new programming to count votes. “If all of the tabulators had been updated as per procedure, there wouldn’t have been any error in the unofficial reporting,” he said.

Poulos also said any discrepancies with the counts from its machines can be investigated by referencing paper ballots and insisted that all audits and recounts of Dominion technology used in the 2020 election have “validated the accuracy and reliability” of the election results. “No one has produced credible evidence of vote fraud or vote switching on Dominion systems because these things have not occurred,” he insisted.

In the normal civilized America that once existed, I would be more prone to believe him. Considering the four years of outright lying that Democratic Party officials and their supporters have subjected us to, from a Russian collusion hoax to a fake Ukrainian impeachment of Trump to endless lies relating to COVID-19 lock downs to lying about the actual spying on Trump by the Obama administration to lying to the FISA court to obtain fake warrants to lying about Brett Kavanaugh and others, it is unreasonable for anyone to trust this man’s word. It is worthless.

And my opinion in this is not alone. Consider this response to his testimony by one Michigan Republican leader:

Linda Lee Tarver, president of the Republican Women’s Federation of Michigan and former election integrity liaison in the Michigan Secretary of State’s Office, said Thursday that Dominion chief John Poulos’s recent testimony left more questions unanswered than it clarified.

Tarver, who testified at a Michigan election integrity hearing on Dec. 2, said Poulos’s Dec. 15 testimony to lawmakers boiled down to reiterating that “human error” was to blame for an initial Election Day vote discrepancy in Michigan’s Antrim County, where Dominion products were used.

She said some of the questions that Poulos did not address include whether poll workers received proper training on the Dominion system, concerns about whether vote tabulators could use a USB stick to add votes to a candidate, and how prone Dominion systems are to hacking. Tarver also said chain-of-custody questions remained unanswered, and raised concerns about the ability of Dominion machines to connect to the Internet. Poulos confirmed that a small percentage of Dominion machines have Internet connectivity.

The only way to satisfy Republicans that the vote was honest is to allow a full and careful audit by their elected officials, to prove no fraud took place. Of course Democrats should be allowed to participate and question everything, but under no circumstances can they be allowed to dictate any terms on such an audit.

Terraced mesas in Martian crater

December 18, 2020 12:38 pm Robert Zimmerman

Click for full resolution image.

The cool image to the right, reduced and annotated to post here, was a captioned photo released by the Mars Reconnaissance Orbiter (MRO) science team earlier this week. Taken by MRO’s high resolution camera, it shows in color a beautifully stair-stepped mesa located in an unnamed 22-mile-wide equatorial crater in Arabia Terra, the large transitional zone between the lowland northern plains and the southern cratered highlands. As the caption notes,

Several craters in Arabia Terra are filled with layered rock, often exposed in rounded mounds. The bright layers are roughly the same thickness, giving a stair-step appearance. The process that formed these sedimentary rocks is not yet well understood. They could have formed from sand or volcanic ash that was blown into the crater, or in water if the crater hosted a lake.

If volcanic ash, the layers are signalling a series of equal eruptions of equal duration, which seems unlikely. Water is also puzzling because of the equatorial location. Like yesterday’s mystery cool image, water is only likely here at a time when the red planet’s rotational tilt, its obliquity, was much higher, placing this at a higher latitude than it is today.

Regardless, make sure you look at the full image here. This crater floor is chock-full of more such terraced mesas, some of which are even more striking than the sample above.

I have also posted below the MRO context camera photo of the entire crater.

Pennsylvania: zero or little evidence open gyms or restaurants spread COVID-19

December 18, 2020 10:29 am Robert Zimmerman

Chicken Little report: Pennsylvania health officials in one county admitted today that they have found zero evidence that open gyms spread COVID-19, while with restaurants the only evidence of spread is among restaurant workers, not patrons.

[T]wo local government leaders confirm contract tracing shows these businesses had low incidence of spreading the virus. “We were not able to find transmission in gyms, and we had almost no transmission in restaurants,” Montgomery County Chairwoman Dr. Valerie Arkoosh said at a Wednesday press conference.

There is some incompleteness in the contract tracing, but all the tracing they have done has consistently found no justification for closing gyms or restaurants. This data also confirms other data from other states.

But facts don’t matter to Pennsylvania’s Democratic Party governor, Tom Wolf and his cross-dressing health secretary, “Rachel” Levine, a guy who makes believe he is a woman.

Last week, Wolf and Department of Health Secretary Dr. Rachel Levine issued new rules saying restaurants could no longer continue with in-person dining or alcohol sales, and “indoor operations at gyms and fitness facilities are prohibited.”

Those rules are set to expire on January 4, but that still amounts to three-and-a-half weeks of what the restaurant industry is calling a de facto shutdown. Restaurants are able to continue with take out and delivery services.

What difference the lock down will destroy lives and ruin businesses? The important thing is to demonstrate the power and majesty of these government officials.

First flightworthy BE-4 engine delivery now expected in summer ’21

December 18, 2020 9:22 am Robert Zimmerman

Capitalism in space: Tory Bruno, the CEO of ULA, revealed yesterday that Blue Origin will finally deliver two flightworthy BE-4 engines for ULA’s Vulcan rocket this coming summer.

ULA, the Pentagon’s top launch contractor for national security satellites, had initially expected the shipment in 2020 for a debut flight in early 2021, but this was delayed by development hurdles.

The installation of Blue Origin’s reusable BE-4 engines into ULA’s next-generation Vulcan rocket will keep it on track for the debut launch of a moon lander dubbed Peregrine at the end of 2021, ULA Chief Executive Tory Bruno said. The Vulcan rocket has won a slate of key U.S. defense missions through 2027.

“That is now our expectation, that Peregrine will go to space in the 4th quarter of 2021,” Bruno told reporters during a call on Thursday.

Peregrine is a commercial lunar lander being built by Astrobotic for NASA.

More information here.

It appears that ULA thinks the long delay in engine development and delivery from Blue Origin will not delay the planned first launch of Vulcan later in ’21. It appears their long range plan to recover and reuse these engines has caused them to design Vulcan so that they can easily swap out engines, which will allow them to complete that new rocket’s development with the test engines that Blue Origin has already provided, and then switch engines and launch within months.

During Bruno’s press briefing he also noted that they have done a thorough refurbish of the Delta launchpads and have instituted a new policy requiring regular launchpad dress rehearsals, in order to make sure the series of problems that delayed the launch of a Delta-4 Heavy earlier this year will not reoccur.

ESA confirms cause of November Vega launch failure

December 18, 2020 9:09 am Robert Zimmerman

The European Space Agengy (ESA) has now completed its full investigation of a Vega rocket launch failure in November, and confirmed that the initially announced cause of “human error” was correct.

Engineers had installed cables backwards causing the nozzle in the upper stage to go one way when it should have gone the other.

The press release at the link is a wonder of bureaucratic cover-your-behind gobbly-gook, saying much without providing any concrete information about the corrections imposed. For example, the upper stage structure is built by one company, Airbus, the engine is built by two Russian companies, Yuzhnoye and Yuzhmash, while a fourth company, Avio, supervises the stage’s assembly. The press release makes it a point to not tell us where the error was made by which company, though by vague implication it suggests the error occurred during final assembly by Avio.

If I was a satellite company thinking of buying a Vega launch I would demand a much more straight-forward explanation. Otherwise I’d go elsewhere.

Russia successfully launches another group of OneWeb satellites

December 18, 2020 8:43 am Robert Zimmerman

Russia today successfully launched the first group of OneWeb satellites since that company entered and left bankruptcy, and it did it for the first time from its new Vostochny spaceport.

The Soyuz rocket’s flight path (see the map at the link) also took it for the first time northward over Russia, where it dropped its boosters and stages. No word on whether any villages or homes were hit.

The 36 satellites launched raises OneWeb’s constellation to 110 satellites total.

The leaders in the 2020 launch race:

33 China
24 SpaceX
15 Russia
6 ULA
6 Rocket Lab

The U.S. continues to lead China 39 to 33 in the national rankings. A SpaceX launch, originally set for yesterday, has been delayed until tomorrow due to an tank pressure issue with its upper stage.

Astronomers detect radio signal from an exoplanet’s magnetic field

December 17, 2020 5:10 pm Robert Zimmerman

The uncertainty of science: Astronomers using a Netherlands telescope have detected a radio signal coming from an exoplanet 51 light years away that likely comes from the planet’s magnetic field.

The new research actually began at Jupiter; the researchers had previously studied that planet’s radio emissions and then tweaked those measurements to reflect the effect they expected closeness to the host star and distance from Earth would have had on their observations of an exoplanet.

Then, the scientists consulted observations made in 2016 and 2017 by the Low Frequency Array (LOFAR) in the Netherlands. In addition to the potential signal from Tau Boötes b, the researchers also report that they may have picked up a signal from the star Upsilon Andromedae or its planet, but that detection was even fainter than the one from Tau Boötes b.

Obviously, there are many uncertainties with this data. However, if scientists can begin to measure and characterize the magnetic field of exoplanets it will give them an important new data point for studying them.

Lockdowns likely leading to an increase in suicides among the young

December 17, 2020 4:53 pm Robert Zimmerman

According to new research, the lockdowns that have shuttered all school sports are likely leading to an increase in youth suicides, even as the death rate for young people from COVID-19 is virtually nil.

The article at the link refers to a Washington Post article, which stated:

A survey of high school athletes conducted by the University of Wisconsin this summer found that approximately 68 percent of the 3,243 teens polled have reported feelings of anxiety and depression at levels that typically require medical intervention — nearly 40 percent higher than past studies. The study, which also found that physical activity levels were 50 percent lower for kids than before the pandemic, was labeled “striking and concerning” by one researcher.

The lead researcher of the study at Wisconsin, Tim McGuine, said in an interview in August that “the greatest risk [to student-athletes] is not covid-19. It’s suicide and drug use.”

From the earliest available data in March it was clear that there was no medical reason to shut down the schools (some countries never did and their children did not suffer for it). Since then this early data has been confirmed repeatedly.

Thus, the only reason to shut the schools and youth sports was an expression of unbridled power and panic by elected leaders not interested in data but very much interested in having control over everyone’s lives. Furthermore, that expression of power was not really interested in saving lives in the least, because if it was by this time these corrupt leaders would have rethought their policy and not only opened up the schools but would have ended many of their irrational lock down policies. Instead, they have been doubling down.

And if you don’t think these shutdowns are irrational and merely an expression of power, consider this: In Ohio the government has ruled that high school wrestlers can grapple and fight, but if they dare shake hands after the match they will be violating social distancing rules.

But it’s “SCIENCE!” they scream! I say, they are liars, both to us and to themselves.

A splat on Mars

December 17, 2020 2:23 pm Robert Zimmerman

Click for full image.

Cool image time! The photo to the right, cropped to post here, was taken on October 31, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labelled simply as a “Terrain Sample”, it was not taken as part of any specific science research but because the MRO science team need to regularly take pictures to maintain the camera’s temperature. When such engineering images are required they try to pick spots of some interest, but sometimes the resulting picture is somewhat bland.

If you look at the full image, you will see that blandness generally describes it. However, in the upper left corner was a most intriguing-looking crater, which I have focused on above. From all appearances, when this impact happened the ground was quite soft, almost like mud, and thus the ejecta splattered away not as individual rocks and debris but as a flow.

The map below gives a little context, but really doesn’t explain this crater fully.

Using origami to design spaceship fuel bladders

December 17, 2020 12:44 pm Robert Zimmerman

Capitalism in space: Engineers at Washington State University have developed a new design for a collapsible fuel bladder for spaceships using as its basis the Japanese art of origami.

Washington State University researchers have used the ancient Japanese art of paper folding to possibly solve a key challenge for outer space travel – how to store and move fuel to rocket engines. The researchers have developed an origami-inspired, folded plastic fuel bladder that doesn’t crack at super cold temperatures and could someday be used to store and pump fuel.

The advantages of a fuel tank that will shrink as it empties are numerous. It appears that nothing that has been tried so far has worked as well as this new design. If proven viable, it will change radically how interplanetary spaceships are designed. It will also make interplanetary missions more practical.

The audit in Arizona

December 17, 2020 11:34 am Robert Zimmerman

My representative in the Arizona house, Mark Finchem, send out an email yesterday outlining in detail the demands of the two subpoenas the state senate has now served on the Maricopa County (covering Phoenix) board of elections. The requirements appear quite thorough:

The first calls for a scanned ballot audit, to collect an electronic ballot images cast for all mail-in ballots counted in the November 2020 general election. The subpoena is narrowly tailored to just Maricopa County. Using the ballot images, the Audit Team will likely utilize extremely sensitive optical scanning software designed to identify phony ballots from legitimate, machine completed versus legitimate voter completed. And. of those ballots that fall into the “suspect” category, the candidate can be identified from the ballot. This means that if a ballot is found to be illegitimate, a count can be made tied directly to the candidate who claimed the vote.

The second subpoena calls for a full forensic audit of ballot tabulation equipment, the software for that equipment and the election management system used in the 2020 General Election. This audit will go deeper than just the elections software written by Maricopa County that was used on the Dominion equipment, wit will include the source code and underlying software that runs the so-called tabulation system.

The Maricopa County Board of Supervisors must answer the subpoena’s on or before 5:00 pm on December 18, 2020.

The first subpoena will make sure that fake ballots were not scanned, and if they were, they can be invalidated so that a new correct count can be done.

The second subpoena will next look at the Dominion tabulators to see if they were correctly tabulating the count. If it finds that they were counting the ballots scanned correctly, that will be wonderful news. If it is instead found that they were not, than a manual handcount will be required, and this evidence will further confirm the allegations in other states that these machines are unreliable and might even be designed to defraud the vote.

Finchem also noted in the email that if the audits find that any of the allegations are true, than the investigation will be expanded to cover other counties.

Based on this information, it appears that the Arizona state legislature is now serious about investigating the election count to make sure it was legitimate.

United kicks family off plane because 2-year-old won’t wear mask

December 17, 2020 10:59 am Robert Zimmerman

Insanity: United Airlines last week removed a family from a flight heading to New York because they were unable to get their 2-year-old child to wear a mask.

In a two-minute video posted on Dec. 11, since removed for no apparent reason by Instagram and Twitter, mother and Colorado resident Eliz Orban tearfully describes the experience then inserts footage of her masked husband attempting to put a surgical mask on the little girl while seated in the plane. The girl holds her hands up to her face, cries, and buries her head in his arm to avoid the mask.

As a flight attendant advises passengers over the comms to stow their baggage. A male flight attendant arrives at the aisle and demands the couple “grab their belongings and exit the aircraft,” saying he gave the couple “every opportunity” to get a mask on the child.

“We’re over here holding this mask over her face,” the father objects as he cradles the little girl. The video clearly shows him holding a neck gaiter over his daughter’s mouth and nose with a clasped hand. “You’ve got to be kidding me,” he says quietly.

The attendant states firmly that “if there’s non-compliance,” it is United’s policy to remove passengers from the flights. “This is compliance,” the father pleads, as the mother, holding the camera, reiterates their attempts to keep their toddler’s face covered.

You must watch the video to see how crazy and irrational this is. The father is holding her with a mask covering her face, even if it isn’t on her. More important, children don’t get COVID-19. Children don’t infect others. And the child is clearly not sick. To demand a mask on her makes no sense.

And yet, this is what airlines are demanding, even though the article also outlines further the technical reasons that make this policy pointless, including the documented claim by United that the passenger areas are already far more free of any aerosols that might carry the virus than any home or normal indoor space.

It is all empty panic and feel-good nonsense. While it can be argued that used properly in the right circumstances masks can have a limited benefit, this policy, which all the airlines seem to be following, is based on fear, idiocy, and irrationality. If anything, the misuse of masks in this situation (note in the video that the father has to hold the mask with his hands, which are a prime source of infection) might actually be increasing the spread of disease.

Election fraud in Nevada

December 17, 2020 10:12 am Robert Zimmerman

The testimony embedded below by Jesse Binnall, one of the lawyers for Trump that conducted research into the election in Nevada, is quite shocking if true. He is speaking to the state’s senate’s Homeland Security and Government Committee at a hearing this week.

[Youtube, being a tool of the Democrat Party election machine, has removed the first upload. I have found it elsewhere.]

Part of his testimony is further confirmed by a separate investigation that found almost 4,000 non-citizens voted illegally.

Under a subpoena, the state’s GOP obtained data that showed green card holders and non citizens who had obtained driver’s licenses. From this official data set, the Nevada GOP “compared this detailed information against the county voter records in Nevada” and “discovered that 6,260 non citizens were registered to vote and 3,987 non-citizens had voted.”

The worst aspect of this is that it is consistent with similar stories and evidence in other states. Such allegations must not be ignored or simply dismissed. They must be investigated, hard.

An update on the testing of SLS’s core stage

December 17, 2020 9:38 am Robert Zimmerman

Link here. The article provides more information on the temperature issue that caused the seventh of eight fueling tests of the core stage to abort early.

The temperature issue arose when NASA transferred superchilled liquid oxygen, to fuel the rocket, from a holding facility to the core stage of the SLS. This procedure has been modeled and verified before, Julie Bassler, SLS stages manager at Marshall, told reporters during the same teleconference. But this was the first time the transfer actually took place.

“We were actually just a few degrees different than what we wanted to see coming in,” she continued, but said the temperature must be precise during the initial phases of filling the tank. The requirement is minus 290.57 degrees Fahrenheit (minus 179.21 degrees Celsius.) But the liquid oxygen was slightly cooler, at minus 296.67 degrees Fahrenheit (minus 182.59 degrees Celsius).

“We filled up [the tank] just enough to pass the phase where we knew we weren’t going to be able to get the temperature to a level that was going to be acceptable to meet the requirement, and that’s when they caught us … in the testing,” Bassler continued.

Despite this issue, NASA still hopes to do the last core stage test, dubbed the Green Run, in the last week in December. During that static fire test they will fuel the core stage entirely and then fire its engines for the full duration of an actual launch — almost ten minutes. If all goes well they will then pack up the stage and ship it to Florida for the planned November unmanned test mission sending Orion around the Moon.

They have no schedule margins, however, because all the components of this very expensive and complex rocket need a lot of time to get anything done. The two solid rocket boosters that will be attached to the sides of the core stage only have a twelve month lifespan once assembled, and they are holding off assembling them pending this test. The core stage itself needs two months to be disassembled, and then two months to be reassembled in Florida. And there remain the issue of a failed power unit in the Orion capsule that could take four to twelve months to repair.

The article however had this telling quote, based on comments from a NASA official, about future launch procedures, that sent a chill up my spine:

House passes bill that attempts to protect Apollo Moon sites

December 17, 2020 9:10 am Robert Zimmerman

The House today passed a bill that would require any American business planning a Moon mission to agree to not disturb the Apollo lunar landing sites.

[The bill] requires any federal agency that issues a license to conduct a lunar activity to require the applicant to agree to abide by recommendations in the 2011 NASA report “NASA’s Recommendations to Space-Faring Entities: How to Protect and Preserve the Historic and Scientific Value of U.S. Government Artifacts” and any successor recommendations, guidelines or principles issued by NASA.

All well and good, but this does nothing to stop other nations from touching those sites. Moreover, making all of those sites and whatever the astronauts did there totally sacrosanct is not reasonable. On the later Apollo landings the astronauts used a rover to travel considerable distances. Should every spot the astronauts visited by now considered holy? If anything, scientists will wish to return and gather more data at these locations to better understand the initial Apollo results.

Not that any of this really matters. In the long run the decision on how much these sites should be protected will be made by the people who live on the Moon. I suspect, as pioneers living on the edge of survival, they will have less interest in making memorials to past achievements and be more focused on getting things done, now.

India successfully completes second launch in 2020

December 17, 2020 8:42 am Robert Zimmerman

Using its PSLV rocket India today successfully placed a communications satellite into orbit.

This was only the second launch by India in 2020. At the start of the year ISRO had predicted they would complete as many as twelve launches. Instead, their panic over COVID-19 shut them down.

The leader board for the 2020 launch race presently stands unchanged, though a SpaceX rocket is on the launchpad and might lift-off in the next 90 minutes. [UPDATE: SpaceX has stood down and will try again tomorrow.]

33 China
24 SpaceX
14 Russia
6 ULA
6 Rocket Lab

The U.S. still leads China 39 to 33 in the national rankings.

Chang’e-5 sample return capsule successfully recovered in China

December 16, 2020 6:18 pm Robert Zimmerman

The new colonial movement: The sample return capsule for China’s Chang’e-5 mission, the first to bring lunar samples back to Earth since 1976, has been successfully recovered in the inner Mongolia region of China today.

Chinese officials confirmed the roughly 660-pound (300-kilogram) capsule landed at 12:59 p.m. EST (1759 GMT) Wednesday, or 1:59 a.m. Thursday in Beijing.

Recovery crews dispatched to the remote landing zone converged on the capsule in helicopters and off-road vehicles, traveling across the snow-covered plains of Inner Mongolia in the middle of the night. Ground teams reached the Chang’e 5 return module within minutes to begin operations to secure the capsule, and planted a Chinese flag in the frozen soil next the spacecraft.

Crews plan to transport the module to Beijing, where scientists will open the sample carrier and begin analyzing the moon rocks.

For China this success is a major milestone for its government-run space program. They have demonstrated superb technical capabilities that will serve them on many more future missions. They have also signaled to the world and the U.S. that they mean business in space, and that their published plans to build colonies on the Moon are serious. They have also made it clear that they will enforce control over any territory they occupy, notwithstanding the rules of the Outer Space Treaty. Any American government that makes light of these facts and refuses to aggressively compete with China is going to quickly discover it shut out of the most valuable locations on the Moon.

InSight: Mars’ crust is thin, and its interior is many layered with a molten core

December 16, 2020 5:13 pm Robert Zimmerman

Scientists yesterday released results from the seismometer on the Mars InSight lander that suggest that the crust of the red planet is thin and that its interior is many layered with a molten core.

[T]wo moderate quakes, at magnitude 3.7 and 3.3, have been treasure troves for the mission. Traced to Cerberus Fossae, deep fissures in the crust 1600 kilometers east of the landing site that were suspected of being seismically active, the quakes sent a one-two punch of compressive pressure (P) waves, followed by sidewinding shear (S) waves, barreling toward the lander. Some of the waves were confined to the crust; others reflected off the top of the mantle. Offsets in the travel times of the P and S waves hint at the thickness of the crust and suggest distinct layers within it, Brigitte Knapmeyer-Endrun, a seismologist at the University of Cologne, said in an AGU presentation. The top layer may reflect material ground up in the planet’s first billion years, a period of intense asteroid bombardment, says Steven Hauck, a planetary scientist at Case Western Reserve University.

At 20 or 37 kilometers thick, depending on whether the reflections accurately trace the top of the mantle, the martian crust appears to be thinner than Earth’s continental crust—a surprise. Researchers had thought that Mars, a smaller planet with less internal heat, would have built up a thicker crust, with heat escaping through limited conduction and bouts of volcanism. (Though Mars is volcanically dead today, giant volcanoes dot its surface.) A thin crust, however, might mean Mars was losing heat efficiently, recycling its early crust, rather than just building it up, perhaps through a rudimentary form of plate tectonics, Mojzsis says.

The thin crust provides a solid basis for explaining the large volcanoes and vast lava plains on the planet. Combined with the light gravity, magma would have found an easier path to the surface. Handed this knowledge, planetary geologists can now make a first stab at outlining more precisely the planet’s early volcanic history.
