TESS completes primary mission

9:33 am

Having now imaged 75% of the entire night sky and completing its primary mission, scientists have now begun the extended mission for the Transiting Exoplanet Survey Satellite (TESS), designed to look for transiting exoplanets.

TESS monitors 24-by-96-degree strips of the sky called sectors for about a month using its four cameras. The mission spent its first year observing 13 sectors comprising the southern sky and then spent another year imaging the northern sky.

Now in its extended mission, TESS has turned around to resume surveying the south. In addition, the TESS team has introduced improvements to the way the satellite collects and processes data. Its cameras now capture a full image every 10 minutes, three times faster than during the primary mission. A new fast mode allows the brightness of thousands of stars to be measured every 20 seconds, along with the previous method of collecting these observations from tens of thousands of stars every two minutes. The faster measurements will allow TESS to better resolve brightness changes caused by stellar oscillations and to capture explosive flares from active stars in greater detail.

These changes will remain in place for the duration of the extended mission, which will be completed in September 2022. After spending a year imaging the southern sky, TESS will take another 15 months to collect additional observations in the north and to survey areas along the ecliptic – the plane of Earth’s orbit around the Sun – that the satellite has not yet imaged.

So far the telescope has spotted more than 2,100 exoplanet candidates, with 66 confirmed.

All told, TESS has divided the sky into 26 sectors, 13 in the north and 13 in the south. It can only look at one at a time for a month, and scientists use that one month data, collected more than once, to see if there are any changes. Because of the gaps in TESS’s view of each sector, however, it is guaranteed to miss some exoplanets (the majority) whose transits occur when it is not looking.

Imagine if we had 25 more of these space telescopes in orbit, so that each sector could be watched continually. This is totally doable now, and would make it possible to soon create a census of transiting exoplanets across the entire sky.

“The disease may recede, but the stigma lingers.”

9:11 am

Link here. The author notes how his 21-year-old daughter tested positive for the Wuhan virus, exhibited no symptoms at any time, and yet finds now herself too often treated like a leper to be avoided in terror. He then provides a magnificent analysis of this disease’s true threat, which is practically nothing at all when put in proper perspective. Consider just this one example provided by him:

The CDC discloses in only six percent of all coronavirus deaths, “COVID was the only cause” mentioned. For the other ninety-four percent, “there were 2.6 additional conditions or causes per death.” There were 115,495 fatalities where patients got admitted to the hospital with “influenza and/or pneumonia.” Another 93,393 checked in with respiratory failure, while 35,167 arrived amid cardiac arrest. Yet hospital administrators sign COVID on death certificates one hundred percent of the time. Early on, Dr. Deborah Birx publicized the probability that medical facilities overstate numbers of actual coronavirus fatalities

Of U.S.165,000 casualties attributed to COVID, six percent translates that less than ten thousand fatalities were otherwise healthy.

He also notes this:

Over the past couple of weeks, the media, with lackey doctors Fauci and Gottlieb providing imprimatur, double down on hysteria as for several days, COVID cases spiked above 70,000. Even Republican governors cowed under pressure as many states slow or halt reopening economies. For perspective, for the six-month Oct-April 2020, CDC reports up to 56,000,000 seasonal flu cases. This calculates to over 300,000 per day. Currently, the official COVID count stands just over 5 million. Does anyone, ever, refer our annual flu “tradition” as a pandemic? During the recent case spike, deaths never got above 55 percent of the April peaks.

There’s lots more, if only people were willing to read it and put aside their false terror of this disease. Sadly, they are not. His accurate analysis will fall on deaf ears.

SpaceX to build resort near Boca Chica

8:51 am

Capitalism in space: SpaceX is seeking to hire a manager to lead the design and construction of a resort near Boca Chica for future spaceport customers.

The job posting seeks a manger to “oversee the development of SpaceX’s first resort from inception to completion,” with the ultimate aim of turning Boca Chica into a “21st century Spaceport.” That would include overseeing the entire design and construction process, as well as getting all necessary work permits and regulatory approvals, and completing the ultimate build of the facility.

Makes perfect financial sense, assuming Starship does eventually fly. Customers will need and expect a nice place to stay before and after their flights, and SpaceX has the land and is best positioned for providing it. And even if Starship doesn’t fly, during the rocket’s development there is money to be made providing tourists the best viewpoint for watching test flights, while also creating a source of profit independent of actual flight.

It ain’t the national elections in November that matter

2:20 pm

The Declaration of Independence

Much analysis and punditry is on-going in both the conservative and liberal press on whether Trump or Biden will win the presidential election come November. Similarly, those same pundits spend much ink considering the fate of the House and Senate. Will the Republicans retake the House? Will the Democrats retake the Senate?

All important. The fate of our country hangs in the balance, and based on the irrational behavior of the Congressional Democrats these past four years, giving them control of both houses of Congress will not bode well for the nation, especially if the increasingly mentally-incapacitated Joe Biden wins the presidency. Since the 2016 election the Democrats and Washington administrative state have foisted on us a fake Russian collusion investigation and a fake impeachment trial against Trump. They clearly wish to do more. If they win both houses and Trump wins the presidency I predict that within six months they will move to remove him from office, using another set of fake charges but really instigated by their blind hatred of Trump and their refusal to accept defeat in an election.

Even, so these national elections are not the most important elections coming in November. What really will tell the tale for the future is how the elections at the local and state levels play out. For you see, it is those governments by their very actions that give us a peek into the future. What they do will percolate upward with time.

Let us do a quick survey of some of the worst local governments to get an idea who really should be thrown out of office.

Cryovolcanism on Ceres still ongoing?

10:02 am

3D simulation of Occator Crater on Ceres

According to a new detailed analysis of data from the Dawn mission, scientists are now postulating that cryovolcanism in Occator Crater on Ceres began immediately after impact about 22 million years ago and has continued in fits and starts since.

Occator Crater was formed about 22 million years ago by a large impact. As in many other impact craters on Earth and on other planets, a central peak was formed, which collapsed again after some time. About 7.5 million years ago, brine rose to the surface within the remnants of the central peak. The water evaporated and certain salts, so-called carbonates, remained. They are responsible for the prominent bright deposits we see today, called Cerealia Facula, in the center of Occator Crater. Due to the loss of material in the interior, the inner part of the crater subsided. A round depression with a diameter of about 15 kilometers formed.

In the following millions of years, activity concentrated mainly on the eastern part of the crater floor. Through cracks and furrows, brine also rose to the surface there and produced further bright deposits, the Vinalia Faculae. About 2 million years ago the center of the crater woke up again: brine rose to the surface and within the central depression a dome of bright material was formed. “This process continued up to a million years ago and maybe even until today,” Dr. Nico Schmedemann from the University of Münster summarizes.

This hypothesis is further supported by second paper that proposes there remains a reservoir of salty underground liquid water in the tiny planet’s interior. Both add weight to the idea that any object in space that is large enough for gravity to force it into a spherical shape is going to behave like a planet, with a complex and active geology.

The first paper has a lot of uncertainty, however, centering entirely on its dependence on crater counts to determine age. While providing a rough age estimate, the method depends on many assumptions, is indirect, and could easily be entirely wrong.

Air Force terminates development contracts to ULA, Blue Origin, Northrop Grumman

9:44 am

In awarding ULA and SpaceX exclusive launch rights for all launches through 2026, the Air Force also decided to end prematurely the development contracts to ULA, Blue Origin, and Northrop Grumman aimed at helping these companies develop new rockets.

An issue at hand is the termination of the Launch Service Agreement contracts that the Air Force awarded in October 2018 to Blue Origin and Northrop Grumman, as well as to ULA. The purpose of the agreements was to help Phase 2 competitors pay for launch vehicle development and infrastructure. Blue Origin received $500 million; Northrop Grumman $792 million and ULA $967 million. The funds were to be spread out through 2024, and the Air Force from the beginning said the LSAs would be terminated with those companies that did not win a Phase 2 procurement contract.

Despite political pressure to not end the LSAs, the agreements will be terminated, Assistant Secretary of the Air Force for Acquisition Will Roper said Aug. 7 during a video conference with reporters. “We will work with those two companies to determine the right point to tie off their work under the LSA agreements,” Roper said. The intent of the LSAs “was to create a more competitive environment leading into Phase 2,” he said. “The point is not to carry them indefinitely.”

LSA funds supported the development of Blue Origin’s New Glenn rocket and Northrop Grumman’s OmegA launch vehicle. ULA will continue to receive funds for its Vulcan Centaur vehicle.

Almost immediately after the award of these contracts was announced in 2018, ULA and Blue Origin announced one year delays in the development of Vulcan and New Glenn. Apparently, meeting the additional requirements of military’s bureaucracy in exchange for getting the cash slowed development.

Now they won’t be getting a large part of that cash, making the decision to take it a deal with the devil. The delay in development has definitely hurt both companies in their competition with SpaceX. First, it likely has raised the cost and complexity of their new rockets, making it harder to compete in price. Second, the delay has given SpaceX more time to grab more customers while improving its own rockets.

SpaceX initially protested not getting a share of this development money, but has subsequently chosen to no longer pursue such government money for Starship because it doesn’t want itself hampered by obtuse government officials and their mindless requirements.

Meanwhile, Northrop Grumman’s Omega rocket is almost certainly dead. That company took the old big space company approach, structuring development around government cash. Without it there is no R&D money at Northrop Grumman to continue work. Furthermore, Omega was designed to serve only once customer, the military. Without any launch contracts there are no customers for Omega, especially because it likely has too high a launch price.

Dentists: Serious health issues from overuse of masks

2:30 pm

Dentists are now reporting an upsurge in a range of serious dental issues caused by the overuse and misuse of masks, mandated by government.

The new oral hygiene issue — caused by, you guessed it, wearing a mask all the time to prevent the spread of the coronavirus — is leading to all kinds of dental disasters like decaying teeth, receding gum lines and seriously sour breath. “We’re seeing inflammation in people’s gums that have been healthy forever, and cavities in people who have never had them before,” says Dr. Rob Ramondi, a dentist and co-founder of One Manhattan Dental. “About 50% of our patients are being impacted by this, [so] we decided to name it ‘mask mouth’ — after ‘meth mouth.’ ”

…While mask mouth isn’t quite as obvious, if left untreated, the results could be equally harmful. “Gum disease — or periodontal disease — will eventually lead to strokes and an increased risk of heart attacks,” says Dr. Marc Sclafani, another co-founder of One Manhattan Dental. He says the stinky syndrome is triggered by face coverings since wearing a mask increases the dryness of the mouth — and a buildup of bad bacteria. [emphasis mine]

I have highlighted the big lie, “preventing the spread of the coronavirus.” It can’t be done, no one until June ever thought it was possible, and to claim it now suggests a willful stupidity, a blindness to reality, or a eager desire to trumpet a lie for political purposes.

Meanwhile, the health of Americans will continue to suffer, just as their economic situation and their basic rights under the Constitution have suffered. All based on a big lie.

European health officials: Masks are useless, maybe a health problem

12:14 pm

They must be white supremacists! Leading health officials in Denmark, the Netherlands, and Sweden continue to state that there is no scientific evidence masks can prevent transmission of COVID-19, while there is ample evidence that their improper use can lead to many other heath issues.

Others, echoing statements similar to the US Surgeon General from early March, said masks could make individuals sicker and exacerbate the spread of the virus.

“Face masks in public places are not necessary, based on all the current evidence,” said Coen Berends, spokesman for the National Institute for Public Health and the Environment [Holland]. “There is no benefit and there may even be negative impact.”

The point here is that research into the ability of masks to block transmission of a virus like COVID-19 is presently very unsettled and unclear. However, the evidence that masks, when used improperly (as almost everyone does) can be unsanitary and actual transmission points for disease is well documented.

Under such conditions it is unconscionable for governments to mandate their use.
