Dictatorship overthrown in Michigan

11:27 am

A victory for law and freedom: The state senate in Michigan yesterday approved a repeal of the emergency powers law that Democratic Party governor Gretchen Witmer used last year to assume the equivalent of total dictatorial powers.

A Michigan House of Representatives GOP spokesman told news outlets that the chamber will vote on the petition soon. If it does not within approximately one month, or if the vote fails, then voters will decide on whether to repeal the emergency powers law in the next election. Republicans control both chambers of the legislature in Michigan.

If the House follows the Senate, then an emergency declaration will be good for 28 days before requiring the legislature’s approval to be extended.

Of course, the Democrats all voted against this repeal, as they like the idea of giving a Democratic Party governor absolute power that cannot be opposed. That the petition was brought to the legislature by the citizens of the state, as per Michigan law, also means nothing to them. They like absolute power, and want to wield it against those citizens.

That the state’s own Supreme Court has also ruled unconstitutional the emergency power law now being repealed, stating it was “an undue ceding of legislative authority to the executive,” makes no difference to the Democrats as well. And Witmer demonstrated this quite starkly when she defied that court ruling and invoked the law again to keep her lockdown of the state on-going, apparently forever.

The Democratic Party today has become the party of dictatorship, corruption, bigotry, and blacklists. Remember that the next time you vote.

Juno team creates dramatic animation of Ganymede/Jupiter fly-by

10:49 am

Using images from Juno’s fly-by of both Ganymede and Jupiter on June 7th and 8th, the science team has produced a dramatic animation, with background music, showing that fly-by from the point of view of the spacecraft.

I have embedded it below the fold.

The 3:30-minute-long animation begins with Juno approaching Ganymede, passing within 645 miles (1,038 kilometers) of the surface at a relative velocity of 41,600 mph (67,000 kph). The imagery shows several of the moon’s dark and light regions (darker regions are believed to result from ice sublimating into the surrounding vacuum, leaving behind darkened residue) as well as the crater Tros, which is among the largest and brightest crater scars on Ganymede.

It takes just 14 hours, 50 minutes for Juno to travel the 735,000 miles (1.18 million kilometers) between Ganymede and Jupiter, and the viewer is transported to within just 2,100 miles (3,400 kilometers) above Jupiter’s spectacular cloud tops. By that point, Jupiter’s powerful gravity has accelerated the spacecraft to almost 130,000 mph (210,000 kph) relative to the planet.

Among the Jovian atmospheric features that can be seen are the circumpolar cyclones at the north pole and five of the gas giant’s “string of pearls” – eight massive storms rotating counterclockwise in the southern hemisphere that appear as white ovals. Using information that Juno has learned from studying Jupiter’s atmosphere, the animation team simulated lightning one might see as we pass over Jupiter’s giant thunderstorms.

The lightning shown on Jupiter, while entertaining, is a complete fantasy. The flashes are much too bright and large. At the scale created, some would cover the Earth. In reality, that lightning wouldn’t be visible until you are very very close, and even then probably difficult to spot in the vastness of Jupiter.

Maezawa reveals status of competition to join him on a private Starship mission to Moon

10:02 am

Capitalism in space: In a video released yesterday Japanese billionaire Yusaku Maezawa provided an update on his Dear Moon competition for choosing the eight individuals who will join him on his private Starship mission around the Moon.

The mission has changed a lot since it was first announced in 2018. Maezawa had planned to invite artists onboard the Starship and venture with them on a circuit around Earth’s only natural satellite. But earlier this year, he changed the process and opened up spots to practically everyone, calling on budding lunar explorers to register for a ticket aboard the Starship and then produce videos on why they want to go to space.

I have embedded the video below. In it Maezawa reveals that he received more than a million applications from every single country on Earth, with many sending short videos describing why they should be chosen. The video provides a sampling of clips from those videos.

What struck me most while watching the video is how completely confident all the applicants were that this private mission on Starship will fly. Even though this is a manned mission around the Moon, something that has only been done nine times, and not for a half century, all seemed entirely sure Maezawa’s mission would happen, and wanted to be on it. I was also struck by the variety of applicants from many places.

Capitalism and freedom is opening the heavens for all humans. And it is about time.

NASA pushing for an SLS launch before the end of the year

9:40 am

According to a statement by NASA administrator Bill Nelson earlier this week, the agency is working hard in its stacking of the SLS rocket in Florida, with the goal of launching before the end of the year.

That statement was revealed in the last sentence of this article describing the work on getting SLS ready, work that appears to be moving along briskly with few surprises.

The present official targeted launch date is set for November. The agency had said it would take between six to ten months to get the rocket ready after the core stage arrived at Kennedy in May. This pointed to a launch sometime between November and March. Right now it appears that NASA is trying very hard to meet that earlier date.

This aggressive effort to launch on schedule is behavior quite out of character for the NASA of the past three decades. In the past, the agency would have moved leisurely along, so that those four months of margin would have almost certainly been used and the launch would have been delayed until March.

I suspect this push now to launch on time is partly generated by a fear that SpaceX’s Starship will reach orbit before SLS. If that happens it will be a major embarrassment to NASA, considering that the agency has spent about three times longer and ten times more money on its rocket than SpaceX.

Isn’t competition wonderful? It even makes government work more efficiently.

Stay tuned. There is still a lot of time between now and November. This race between comparable rockets being built by the government and a private company appears to be neck and neck as we head down the stretch.

Thales Alenia to build first two modules of Axiom’s commercial space station

9:24 am

Capitalism in space: The Italian company Thales Alenia today announced it has finalized the contract to build the first two modules of Axiom’s private commercial space station, set to be docked to ISS initially but eventually to fly independent once ISS is decommissioned.

Total price for the contract is 110 million euros. According to the press release, they are targeting 2024 and 2025 for launching these modules, which will be able to house as many as eight residents.

Based on its past successful experience in building modules for the International Space Station, Thales Alenia Space is responsible for the design, development, assembly and test of the primary structure and the Micrometeoroid & Debris Protection System for the two Axiom modules.

The welding activities of the primary structure of the first module will start in September 2021, with the assembly process concluding in 2022. The first module will arrive at Axiom facilities in Houston in July 2023, where Axiom will integrate and outfit the core systems and certify it for flight prior to shipping to the launch facility.

With the launch of this station, human spaceflight in the United States will become completely independent of the federal government. Private companies will own the rockets, spacecraft, and stations, and the government will no longer have a major say on what goes on in space. The NASA bureaucracy that makes getting an experiment onto ISS cumbersome, difficult, and discouraging will be out of a job. (An example: In the 2000s American scientists studying plant growth in weightlessness ended up launching their experiments with the Russians because getting NASA approval turned out to be too difficult.)

This doesn’t mean that it will be easy to get a payload or experiment onto Axiom’s station. The demand will be quite high. It just means that the decision will no longer reside with the government, but with the private companies and citizens of the United States.

As it always should have been.

Furthermore, that the demand is going to exceed the supply will mean that additional stations will be built, and quickly, because the lure of profit will be there. For example, many of the commercial medical experiments that were on the verge of paying off but were shut down after the Challenger accident in 1986 could very well be brought back to life.

Engineers report Hubble fix appears successfully

8:50 am

Engineers this morning announced that their attempt to switch to backup computer hardware on the Hubble Space Telescope was successful.

The switch included bringing online the backup Power Control Unit (PCU) and the backup Command Unit/Science Data Formatter (CU/SDF) on the other side of the Science Instrument and Command & Data Handling (SI C&DH) unit. The PCU distributes power to the SI C&DH components, and the CU/SDF sends and formats commands and data. In addition, other pieces of hardware onboard Hubble were switched to their alternate interfaces to connect to this backup side of the SI C&DH. Once these steps were completed, the backup payload computer on this same unit was turned on and loaded with flight software and brought up to normal operations mode.

They are now doing tests to make sure everything is working as expected, and preparing the telescope to bring it out of safe mode and resume science operations.

This is great news, but to bring everyone down to Earth, we must remember that Hubble no longer has any redundancy in this area. Should there be another similar computer failure, the telescope will then be dead in the water, with the only way to bring it back a manned or robotic mission — something we presently do not have the capacity to do — to replace these units.

Arizona election audit uncovers more evidence of malfeasance in November 2020 election

4:01 pm

In hearings today before the Arizona Senate, election audit officials described strong evidence of misconduct and election fraud in Maricopa County, the state’s largest.

Several issues were quite startling. First,

Audit expert Doug Logan revealed during Thursday’s Arizona state election hearing that auditors had reported there 74,000 mail-in ballots received and included in the 2020 election that were never recorded as being mailed out.

Ballots are not something that appear out of thin air. They are only supposed to be provided by the election board, under very strict rules. For there to be 74,000 voted ballots that the board never issued is suspect, to say the least.

Second,

the hearing revealed that 11,326 voters in Maricopa County were not on voter rolls on Nov. 7 but were on voter rolls on Dec. 4 and were marked as having voted in the Nov. 3 election.

That’s more than eleven thousand votes from people who were not registered to vote on election day.

Finally, they discovered that the record-keeping made it difficult if not impossible to match up duplicate ballots with the originals. According to the system used in Arizona, duplicate ballots are sometimes generated manually when the original is damaged and cannot be read by the tabulator. When this happens, the duplicate is supposed to include a serial number linking it to the original. This way no one can generate many duplicate (and fake) ballots to help their preferred candidate.

The audit found numerous duplicates with no serial numbers, meaning they could have been generated by someone to help their preferred candidate.

Would these these facts have changed the outcome? This is not known yet. We will have to wait until the final report, expected in August. Either way, these problems prove that the election was, at the least, poorly run, with the strong likelihood that actual criminal conduct occurred. And that last allegation is reinforced by the stone-walling of Maricopa County’s election board, which apparently does not want anyone to take a close independent look at what they have been doing.

Today’s blacklisted Americans: Opponents of critical race theory in Virginia subjected to harassment campaign

11:40 am

Rick, stating the truth in Casablanca
Are Americans finally waking up?

They’re coming for you next: The parents in Virginia who are putting together a campaign to keep the teaching of the Marxist and racist program called “critical race theory” out of their local schools have been subjected to a harassment campaign that included hate mail, threats, and even slanderous letters sent directly to their employers.

One example cited in the article:

An anti-critical race theory (CRT) activist, Jessica Mendez, says that in June her employer was sent a flyer that called her an “active racist.” “You should be ashamed to employ a known and active racist!” the flyer, obtained by Daily Caller, read. The flyer added, “Yes, what is wrong with her? She’s a racist!!”

It further showed photos of Mendez at various anti-CRT rallies protesting the curriculum of Loudoun County Public Schools. Loudoun County has been at the center of a revolt against the implementation of CRT in school curricula that has spread across the country.

Winner of Blue Origin auction for suborbital flight will not fly on July 20th

11:13 am

Capitalism in space: Blue Origin today announced that the $28 million winner of the auction to buy a seat on the first commercial flight of its suborbital spacecraft New Shepard on July 20th will not be on board, and will instead be replaced by an 18-year-old.

Blue Origin announced Thursday that instead of a $28 million auction winner launching with founder Jeff Bezos on Tuesday, Dutch runner-up Oliver Daemen will be on board. The company said he’ll be the first paying customer, but did not disclose the price of his ticket. …According to Blue Origin, Daemen took a year off after graduating from high school last year to obtain his private pilot’s license. He’ll attend the University of Utrecht in the Netherlands in September. His father is Joes Daemen, founder and CEO of Somerset Capital Partners, a private equity firm in Oisterwijk, Netherlands. Both father and son are already in the U.S. preparing for the launch, according to a company representative.

…Blue Origin said the yet-to-be-identified winner of the charity auction is stepping aside because of a scheduling conflict and will catch a future flight. Daemen was going to be on the second launch for paying customers.

The company has yet to open ticket sales or disclose its prices to the public. That’s expected following Bezos’ flight.

There are some puzzles here. Did Daemen bid during the auction? Was his bid second? If not, why has he been pushed to the head of the line, even before Blue Origin has opened ticket sales or announced its prices?

Moreover, much of this does seem to be hype and pr, rather than real achievement. More important would be an announcement saying that the BE-4 engine is finally ready, making possible orbital flights on New Glenn and ULA’s Vulcan rocket.

Nonetheless, it is nice that Bezos is taking this teenager into space, as is his decision to also give a seat to 82-year-old Wally Funk, one of the women who applied to fly during the Mercury program in the 1960s but was rejected.

New research: COVID is harmless to children

11:03 am

Surprise, Surprise! A new study of all hospital admissions in England from March 2020 through February 2021 found that, for people younger than 18 deaths from COVID-19 were “incredibly rare.”

Of 3,105 deaths from all causes among the 12 million or so people under 18 in England between March 2020 and February 2021, 25 were attributable to COVID-19 — a rate of about 2 for every million people in this age range. None had asthma or type-1 diabetes, the authors note, and about half had conditions that put them at a higher risk than healthy children of dying from any cause.

Taken together, the unusually comprehensive studies could provide some comfort to parents who have been shielding children who they thought might be vulnerable to severe complications from COVID-19. “There’s a general feeling among paediatricians that probably too many children were shielded during the first wave of the pandemic,” Russell Viner, who studies adolescent health at the University College London, told reporters.

In some cases, those efforts might have done more harm than good, added Elizabeth Whittaker, an infectious-disease specialist at Imperial College London. “Shields are very leaky,” she said. “The shields have not been perfect, and have probably caused more stress and anxiety for families than benefit.”

This study merely proves what common sense has known for eons, and was backed up by decades of research, both before and after the arrival of COVID-19. To kill an epidemic of a flu-like disease like COVID, the best thing you can do is to expose as many healthy children as possible to it, while keeping those children away from the more vulnerable elderly population. The children will quickly gain immunity, without risk, and then help limit the spread of the disease. More important, once immune they and their grandparents can once again see each other, with no risk to either.

Instead, today’s modern panicky and emotional expert class shut everything down, and ended up causing more harm than necessary, in all ways. Businesses were destroyed, old people died in solitary confinement, and children were subjected to child abuse with masks and social distancing.

Worse, that expert class still refuses to admit it was wrong, and in many ways is doubling down on its stupid. Witness the government’s top expert, Anthony Fauci, and his claim only yesterday that COVID-19 is dangerous to children and that toddlers older than two need to wear masks. He, like most of the government health officials who have been given vast power in the past year, speaks not from data but from his own personal opinion, shaped solely by politics.

Thailand’s government approves new space law

10:00 am

The new colonial movement: The cabinet of Thailand has approved a new space law that will establish a space agency and establish a regulatory framework for both its private and public space industry.

The core principles included the planning of a policy to support both state and public sector participation in a “new space economy”, the creation of a national space policy committee to draw up space policy. The bill also sets up a national space administration agency to perform secretarial tasks for the national space policy committee, with a director that will have the power to appoint officials.

As the language of the bill is not available, it is unclear exactly what the bill does, other than establish a government framework for Thailand’s space industry. Its passage however illustrates the growing international passion for joining the new commercial effort in space. Thailand apparently does not wish to be left behind.

India successfully completes static fire testing of rocket engine for human flights

9:55 am

The new colonial movement: India has successfully completed the third long duration static fire tests of its Vikas rocket engine, to be used on its planned manned space mission dubbed Gaganyaan.

[T]he Vikas engine is the workhorse liquid rocket engine powering the second stage of India’s Polar Satellite Launch Vehicle (PSLV), second stage and the four strap-on stages of the Geosynchronous Launch Vehicle (GSLV) and the twin-engine core liquid stage (L110) of GSLV Mk-III.

Experts point out that the successful testing is necessary as the testing is part of the human rating of a rocket that was not originally designed to launch humans into space. Every space agency follows its own standards of human rating of a launch vehicle and there are no global standards. “This test is one of the critical items which need to be checked in human rating GSLV Mk-III. Semi-Cryogenic engine SE-200 which will replace Vikas is still under development and its developmental times will not match the ambitious Gaganyaan timelines. Vikas is one of the most reliable engines in the world and has proved its mettle.

If you look at PSLV, GSLV Mk-II and GSLV Mk-III missions where Vikas has been used, the burn profile or duration is approximately around 150-160s only on a typical flight. Testing its performance above its designed operational limit is essential to ensure engine reliability against any event of a mishap.

In other words, for the manned mission Vikas will have to burn for a much longer time than its normal profile. They have now successfully shown that it can handle that long burn time.

Bezos donates $200 million to Air & Space Museum

9:48 am

Jeff Bezos, founder of Amazon and Blue Origin and about to fly on the first commercial suborbital flight of his New Shepard spacecraft, today announced the donation of $200 million to the Air and Space Museum in Washington, DC.

The Smithsonian said $70 million of the money would support museum renovations. The other $130 million would go toward building a new education center at the museum called the Bezos Learning Center to inspire students to promote innovation and explore careers in science, math and engineering.

While this is a very gracious and generous act, in the long run it might actually have been better for Bezos to have used this money to get his rocket company off the ground. Success in that manner would be far more effective in inspiring students. Once Blue Origin is actually launching humans into orbit to explore the heavens such a donation might have made better sense. Those student would not only be inspired by the achievement, Bezos would then be providing them a way to join in.

Still, the gift will do much to help maintain the nation’s capabilities in space. Good for Bezos.

FAA threatens shutdown of SpaceX’s Starship program at Boca Chica

9:33 am

Banned by the FAA?
Starship banned by the FAA?

They’re coming for you next: An FAA official revealed yesterday that the agency has not approved the launch tower that SpaceX is building for its Starship/Superheavy rocket in Boca Chica, Texas, and threatened that if disapproved the government would force the company to tear it down.

The Federal Aviation Administration warned Elon Musk’s SpaceX in a letter two months ago that the company’s work on a launch tower for future Starship rocket launches is yet unapproved, and will be included in the agency’s ongoing environmental review of the facility in Boca Chica, Texas. “The company is building the tower at its own risk,” an FAA spokesperson told CNBC on Wednesday, noting that the environmental review could recommend taking down the launch tower.

The FAA last year began an environmental review of SpaceX’s Starship development facility, as Musk’s company said it planned to apply for licenses to launch the next-generation rocket prototypes from Boca Chica. While the FAA completed an environmental assessment of the area in 2014, that review was specific to SpaceX’s much-smaller Falcon series of rockets.

This revelation from FAA officials is most interestingly timed, coming on the same day as this garbage article about the terrible environmental damages some activists imagine SpaceX’s launch facility might someday cause. As is usual for a mainstream news source, the article makes no reference to the wildlife preserve that surrounds the Kennedy Space Center in Florida, where we have empirical proof for more than a half century that a spaceport does no harm to the environment and actually acts to protect it from development.

Nor was this the only such attack article in the past two days. Here is just a sampling:

Evidence found proving Georgia ballots were counted multiple times in 2020 election

3:31 pm

The audit of 147,000 ballots in Fulton County, Georgia, has now found definitive proof that the same ballots were counted multiple times, thereby manufacturing fake votes.

The link takes you to a Twitter video showing examples of several absolutely identical ballots that were run through the tabulators multiple times to produced fake votes. The multiple scans were also done on the same tabulator, meaning it was likely done by the same person.

This proves that there was vote tampering in Fulton County. The investigation now has to determine who did it, which will be possible because the ballots show the tabulator used and when. Linking this to footage on security cameras will determine the perpetrator.

The audit also has to determine the extent of the fraud. One or two ballots tabulated twice is not significant. There is other evidence that suggests thousands of ballots were tabulated improperly and intentionally in this manner. If the audit demonstrates this, and calculates the number of votes involved, it could prove the election in Georgia was invalid.

At a minimum it proves that Georgia needs a complete overall of its election system, including a complete house-cleaning of all involved, especially in Fulton County.

UPDATE: Read this detail report on the new allegations and discoveries that point to outright fraud in the Georgia November 2020 vote tallies. It captures the whole story very nicely.

Blue Origin distributes $19 million of the $28 million earned for its July 20th suborbital flight

1:23 pm

Blue Origin today announced the nineteen non-profits that will receive $1 million each, taken from the $28 million that a single as-yet unnamed person is paying to fly with Jeff Bezos on the first commercial suborbital manned flight of New Shepard on July 20, 2021.

All of the organizations are advocates for space exploration. A majority foster education for the young. Two are pro-women, pushing gender politics in space.

The remaining $9 million will be used by Blue Origin’s non-profit to encourage space-focused curriculum and its project to encourage people to send postcards into suborbital space on its New Shepard spacecraft.

All in all the list of recipients surprised me. I had expected this money to go to many of the very leftist environmental groups that Jeff Bezos loves. Instead, the list is entirely space-focused, though it does tend to favor organizations that mostly aim to maintain the status quo of a big government space program or push for gender or racial politics. That there is a large variety of organizations that push many different approaches to encouraging space exploration however is refreshing.

Nonetheless, except for a few that actually educate children, most are advocacy groups. Compare that to the charity being produced by SpaceX’s first manned commercial flight in September, dubbed Inspiration4. That flight is pumping big bucks directly into St. Jude’s Research Hospital to help it cure children from cancer.

Which do you think is doing more for the world?

Today’s blacklisted American: School district fires teachers for expressing their opinions publicly

1:00 pm

Modern science!
Modern education in Oregon: Facts don’t matter!

Persecution is now cool! An Oregon school district is moving to fire two teachers because they began a campaign to keep the bathrooms in their schools male and female only.

The teachers are suing the school district to keep their jobs.

Assistant principal Rachel Damiano and science teacher Katie Medart of North Middle School face a pre-termination hearing before the school board Thursday. They are seeking a temporary restraining order (TRO) and preliminary injunction as they continue suing the Grants Pass School District for violating their speech rights under the U.S. and Oregon constitutions.

…The district argues the federal court can’t reinstate Damiano and Medart to their positions, from which they’ve been on paid leave for three months for “inappropriate behavior,” unless the school board accepts the superintendent’s recommendation to fire them.

Hubble update: Engineers pinpoint issue, prepare to fix it

12:38 pm

In an update today on the status for bringing the Hubble Space Telescope back into science operations, the engineers say they think they have pinpointed the failed unit, and are ready to do the switch to a backup.

A series of multi-day tests, which included attempts to restart and reconfigure the computer and the backup computer, were not successful, but the information gathered from those activities has led the Hubble team to determine that the possible cause of the problem is in the Power Control Unit (PCU).

The PCU also resides on the SI C&DH unit. It ensures a steady voltage supply to the payload computer’s hardware. The PCU contains a power regulator that provides a constant five volts of electricity to the payload computer and its memory. A secondary protection circuit senses the voltage levels leaving the power regulator. If the voltage falls below or exceeds allowable levels, this secondary circuit tells the payload computer that it should cease operations. The team’s analysis suggests that either the voltage level from the regulator is outside of acceptable levels (thereby tripping the secondary protection circuit), or the secondary protection circuit has degraded over time and is stuck in this inhibit state.

Because no ground commands were able to reset the PCU, the Hubble team will be switching over to the backup side of the SI C&DH unit that contains the backup PCU. All testing of procedures for the switch and associated reviews have been completed, and NASA management has given approval to proceed. The switch will begin Thursday, July 15, and, if successful, it will take several days to completely return the observatory to normal science operations.

Engineers did a similar switch in 2008, so they are very confident it will work this time also. However, once done, the telescope will no longer have backups for any of these computer modules. The next failure in any of them will shut the telescope down, for good.

Craters on Ganymede’s striped surface

Craters on Ganymede
Click for full image.

Cool image time! The photo to the right, cropped to post here, is a color enhanced section taken from of one of the images taken by Juno when it did a close fly-by of the Jupiter moon Ganymede back on June 7, 2021.

The enhancement was done by citizen scientist Navaneeth Krishnan, using a wider Juno image of Ganymeded enhanced by citizen scientist Kevin Gill. That wider image is below, and marks the area covered by this first image with a white box.

In this one picture we can see many of the geological mysteries that have puzzled scientists since the Galileo orbiter first took close-up images back in the 1990s. We can see patches of grooved terrain with the grooves in the different patches often oriented differently. We can also see bright and dark patches that while they overlay the grooved terrain they bear no correspondence to those grooved patches. And on top of it all are these small craters, impacts that obviously occurred after the formation of the grooves.

NASA awards three contracts to develop nuclear propulsion concepts

10:13 am

Capitalism in space: NASA yesterday awarded three different contracts to three different corporation partnerships to develop new nuclear propulsion concepts for use in space.

The contracts, to be awarded through the DOE’s Idaho National Laboratory (INL), are each valued at approximately $5 million. They fund the development of various design strategies for the specified performance requirements that could aid in deep space exploration.

Nuclear propulsion provides greater propellant efficiency as compared with chemical rockets. It’s a potential technology for crew and cargo missions to Mars and science missions to the outer solar system, enabling faster and more robust missions in many cases.

The contracts went to these partnerships:

  • Lockheed Martin and BWX Technologies
  • Aerojet Rocketdyne, General Atomics Electromagnetic Systems, and X-energy
  • Blue Origin, Ultra Safe Nuclear Technologies, Ultra Safe Nuclear Corporation, General Electric Hitachi Nuclear Energy, General Electric Research, Framatome, and Materion

Once the concepts are put forth at the end of the 12-month contracts, the DOE’s laboratory will review them and make recommendations to NASA for further work.

This contract, along with other NASA contracts to develop nuclear power for use on planetary surfaces, strongly suggests that the fear of using nuclear power in space is receding. If so, the capabilities in space will increase significantly in the coming years.

Facebook gets out of satellite business; “sells” its employees to Amazon

10:02 am

Capitalism in space: Facebook has now apparently abandoned a project to launch its own communications satellites and instead has made a deal with Amazon whereby it sold its satellite division to the Bezos-founded company, where they joined Amazon’s Kuiper communications satellite project.

Over the past year, Amazon has revealed details about Project Kuiper’s antenna design, selected United Launch Alliance’s Atlas V rocket for the initial satellite launches, and acquired still more office space for Kuiper employees in Redmond.

According to The Information, the employees who came to Kuiper from Facebook in April are based in the Los Angeles area. They are said to include physicists as well as optical, prototyping, mechanical and software engineers who have worked on aeronautical systems and wireless networks. One of the employees, Jin Bains, was formerly Facebook’s head of Southern California connectivity and is now described on his LinkedIn page as a director on the Project Kuiper team.

The Information reported that Amazon paid Facebook as part of the deal for the employee switchover, but did not provide further details. “It’s not unheard of for big companies to buy groups of employees from one another, just as they often buy small startups to beef up staff in various parts of their business,” The Information’s Sarah Krouse and Sylvia Varnham O’Regan explained. [emphasis mine]

This deal reveals a number of immediate facts, as well as one long term troubling one. First, it indicates as mentioned Facebook’s abandonment of its space ambitions.

Second, it suggests that Amazon might finally be recognizing that the people running its Kuiper satellite project are taking far too long to get it off the ground. Though proposed approximately the same time as SpaceX’s Starlink constellation, Kuiper remains unlaunched with no launches even scheduled, while SpaceX has more than 1,500 satellites in orbit, has been providing test service to customers in selected areas, and is about to become operational globally. This difference is achievement might be explained by this fact: The person Amazon hired to run its Kuiper project was someone Elon Musk fired in 2018 from his Starlink project because that person was taking too long to get it built and launched.

The new hires suggest that Amazon might have finally recognized this issue.

Finally, the long term troubling fact.

More evidence of shocking fraud in Georgia’s 2020 election tally

2:57 pm

The petitioners in a lawsuit claiming significant fraud and vote tampering in Georgia during the November 2020 election have announced today in a press release [pdf] further evidence that are downright shocking if true.

The VoterGA team found 7 falsified audit tally sheets containing fabricated vote totals for their respective batches. For example, a batch containing 59 actual ballot images for Joe Biden, 42 for Donald Trump and 0 for Jo Jorgenson was reported as 100 for Biden and 0 for Trump. The seven batches of ballot images with 554 votes for Joe Biden, 140 votes for Donald Trump and 11 votes for Jo Jorgenson had tally sheets in the audit falsified to show 850 votes for Biden, 0 votes for Trump and 0 votes for Jorgenson.

Fulton Co. failed to include over 100,000 tally sheets, including more than 50,000 from mail-in ballots, when the results were originally published for the full hand count audit conducted by the office of the Secretary of State for the November 3 rd 2020 election. Those tally sheets remained missing until late February when the county supplemented their original audit results.

Petitioners contend that Fulton County did not provide drop box transfer forms for at least three pickup days when obligated to do so via an Open Records Request. Those missing forms are still needed to provide chain of custody proof for about 5,000 ballots. [emphasis mine]

The evidence suggests that the tally sheets, used to make the final count, are filled with fraud and fabrications designed to steal the election for Joe Biden, changing the totals in the examples given above to remove 151 Trump/Jorgenson votes while adding 296 non-existent Biden votes to the total.

That Fulton County has failed to provide 100,000 tally sheets, and stalled for as long as it could to turn those sheets over, suggests that election officials there were well aware of these and many more fabrications, and wished to hide them.

In other words, they were partners in the crime, and have been trying to conceal this fact. One wonders what we would find if a full audit was done of all 100,000 tally sheets.

Clashing layers in Mars’ largest canyon

Clashing layers on a mountain slope on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on May 27, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows the clash of different layers on the western slope of a mountain within Mars’ largest canyon, Valles Marineris.

The scientist have labeled this a “possible angular unconformity.” In geology an unconformity generally refers to a gap in a series of layers, a period when instead of the layers being deposited they are being eroded away, leaving no record for that time period. An angular unconformity adds tilting to the older layers, which after erosion are then covered by new layers that are oriented somewhat differently.

Based on these definitions, what the scientists suspect is that the brighter layers to the left and lower down the mountain are older. After a period of erosion new layers were deposited on top at a different angle, forming the stripe of layers going from center left up to center right.

The swirly nature of the material on the top of the ridge suggests to me that these layers might be volcanic in nature, but that’s a pure uneducated guess. What some scientists do believe (but have not yet conclusively proven) is that the lower older layers are sediments laid down by an ancient lake that once filled the canyon here.

The overview map below provides a wider view and some context.

Scientists successfully predict resumption of bursts from magnetar

12:14 pm

The uncertainty of science: Though they have no real idea why it happens, scientists have now successfully predicted the resumption of energetic bursts coming from a magnetar and according to schedule.

The researchers — Grossan and theoretical physicist and cosmologist Eric Linder from SSL and the Berkeley Center for Cosmological Physics and postdoctoral fellow Mikhail Denissenya from Nazarbayev University in Kazakhstan — discovered the pattern last year in bursts from a soft gamma repeater, SGR1935+2154, that is a magnetar, a prolific source of soft or lower energy gamma ray bursts and the only known source of fast radio bursts within our Milky Way galaxy. They found that the object emits bursts randomly, but only within regular four-month windows of time, each active window separated by three months of inactivity.

On March 19, the team uploaded a preprint claiming “periodic windowed behavior” in soft gamma bursts from SGR1935+2154 and predicted that these bursts would start up again after June 1 — following a three month hiatus — and could occur throughout a four-month window ending Oct. 7.

On June 24, three weeks into the window of activity, the first new burst from SGR1935+2154 was observed after the predicted three month gap, and nearly a dozen more bursts have been observed since, including one on July 6.

They made this prediction based on data going back to 2014 that showed the three-month-off/four-month-on pattern.

As to why this pattern exists, they presently have no idea. Theories have been proposed, such as starquakes activated by the magnetar’s fast rotation or blocking clouds of gas, but none are really very convincing, or are backed with enough data.
