Arctic ozone hole closes

10:13 am

The uncertainty of science: The largest ozone hole ever detected over the north pole has now closed.

After looming above the Arctic for nearly a month, the single largest ozone hole ever detected over the North Pole has finally closed, researchers from the European Union’s Copernicus Atmosphere Monitoring Service (CAMS) reported. “The unprecedented 2020 Northern Hemisphere ozone hole has come to an end,” CAMS researchers tweeted on April 23.

The hole in the ozone layer — a portion of Earth’s atmosphere that shields the planet from ultraviolet radiation — first opened over the Arctic in late March when unusual wind conditions trapped frigid air over the North Pole for several weeks in a row. Those winds, known as a polar vortex, created a circular cage of cold air that led to the formation of high-altitude clouds in the region. The clouds mixed with man-made pollutants like chlorine and bromine, eating away at the surrounding ozone gas until a massive hole roughly three times the size of Greenland opened in the atmosphere, according to a statement from the European Space Agency (ESA). [emphasis mine]

Note that the north pole hole occurred because of unusually frigid and cold conditions, something I thought we were never going to see again because of global warming.

The last paragraph of the article at the link reveals a lot of ignorance by its writer, Brandon Specktor, where he discusses the south pole ozone hole. First, he says it “has existed for roughly four decades.” Wrong. The south pole ozone hole was first detected in the 1950s, and has likely existed every winter for eons.

Next, he wonders if it is “starting to close.” Wrong. That ozone hole opens every winter and closes every summer, like clockwork. When winter arrives and the south pole is in darkness, oxygen molecules are no longer being ionized by sunlight and thus there is a drop in the production of ozone, producing the hole. When sunlight begins hitting the upper atmosphere in the spring it starts ionizing oxygen molecules again to produce ozone, and the hole goes away.

Then he notes that scientists hope the hole will “heal” and forever disappear by 2050. Wrong. The data says instead that the south pole ozone hole is a natural phenomenon that occurs every winter. It is not a wound against the earth.

Finally, he claims that the south pole ozone hole exists almost entirely because of us evil humans, first because of global warming and second because until 1987 we put ozone-depleting pollutants into the atmosphere. Wrong. As I said, the ozone hole is almost entirely a natural phenomenon, caused each winter because sunlight is no longer hitting the upper atmosphere above Antarctica and thus oxygen molecules are no longer being ionized into ozone. Those pollutants might have made it slightly larger in the late 20th century, but then, that theory has a problem, as most of those pollutants were released in the northern hemisphere, where they would have little or no interaction with the atmosphere of the southern hemisphere. (The atmospheres of the two hemispheres are largely independent.) Yet it was only in the south that we have generally seen an ozone hole

I predict, very confidently, that come 2050 climate scientists will discover, “unexpectedly”, that the south pole ozone hole has not “closed” or “healed”, but continues to reappear, each winter. And they will have by then discovered that depending on circumstances, a north pole ozone hole also appears during some colder winters, which despite their repeatedly failed predictions of global warming will likely continue to happen.

UAE’s Mars probe arrives in Japan for launch in July

9:31 am

The new colonial movement: The United Arab Emirates’ (UAE) Mars orbiter, dubbed Hope, has arrived at its launch site in Japan in preparation for its July launch on a Mitsubishi H-2A rocket.

Previously I had thought the probe had been built in the UAE with help from engineers from India, but that was not the case. Instead, the probe was mostly built by Americans, in America.

Carrying three science instruments, the Hope mission will measure conditions in the Martian atmosphere from a unique semi-synchronous orbit high above the Red Planet. The mission is the first from the Arab world to travel to another planet.

About the size of Mini Cooper, the spacecraft was assembled at LASP’s facilities in Colorado [Laboratory for Atmospheric and Space Physics], with the help of Emirati engineers and scientists. The probe was delivered to Dubai in February for additional testing, and then was supposed to be transported to Japan in early May.

But the coronavirus pandemic forced officials to shuffle the schedule, and mission managers decided to send the probe to Japan early. [emphasis mine]

In other words, this probe might be financed by the UAE, and it might have UAE engineers and scientists involved, but essentially the UAE paid LASP to build it for them.

I am not criticizing the UAE for this effort, but to call it an Arab mission is somewhat dishonest. This is a joint American-UAE probe. If it results in producing qualified engineers in the UAE capability of building their own future planetary probe, fine. They are not doing it now, however.

Successful static fire Raptor engine test on 4th Starship prototype

9:19 am

Capitalism in space: SpaceX yesterday successfully completed the first static fire Raptor engine test on its fourth Starship prototype, laying the foundation for a planned 150-meter vertical hop later this month.

The test lasted about three seconds.

I want to make a quick comparison between SpaceX’s approach for developing Starship, and NASA’s development of SLS. The differences are stark.

First, SpaceX began cutting metal a little over one year ago, and is already testing a full scale prototype, fully fueled, with its planned flight engine.

SLS began development officially around 2011. It uses the engines from the Space Shuttle, so those are already flight proven. However, even after almost a decade of development NASA as yet to do a single static fire test with those engines actually installed on an SLS rocket, either a prototype or the real thing.

Second, in the past year SpaceX has been aggressively testing the fueling of Starship, using a series of prototypes. With this fourth iteration they have apparently gotten the fueling process and the tanks to work effectively. Further tests of course will increase their confidence in the system’s reliability.

SLS, even after almost a decade of development, has yet to do any similar tank tests. Instead, NASA has done separate individual tests of the rocket’s tanks, but never with everything fully assembled. The agency, and its lead contractor Boeing, hope to finally do their first full scale SLS tank test and static fire test sometime later this year. As they have never filled the tanks in this manner before, they have admitted that problems could arise, including the possibility that the tanks could leak.

Note the big difference. SpaceX has done this testing very early in development. NASA is doing it very late in development. Which to you seems the better approach?

China has problem with test “cargo return capsule”

9:01 am

According to China’s propaganda state-run news, an “inflatable cargo return capsule ” launched on yesterday’s Long March 5B rocket “operated abnormally” during its return to Earth.

That’s all they tell us. The description suggests this is not the test manned capsule launched by the Long March 5B, but the text is vague enough that it could be, since that unmanned capsule was supposedly going to return to Earth in one or two days.

At the moment I have not seen any other updates on the status of that manned capsule. If the problem was with it, this issue could delay their manned space station program, scheduled to go into full operation by 2022.

The closest black hole: 1,000 light years away?

8:48 am

The uncertainty of science: Astronomers now think they have detected evidence of a stellar-mass black hole only a thousand light years away and orbiting a star system that is visible to the naked eye.

Thomas Rivinius, an astronomer with the European Southern Observatory (ESO), and his colleagues studied the unusual star system HR 6819 in this way using a 2.2-meter telescope in Chile, operated by ESO and the Max Planck Society. They thought it was a binary system, but there was an extra wobble in the periodic light shifts of one of the stars that indicated something else was asserting its presence. It turned out to be a triple system, with one star in a fast 40-day orbit with an unseen companion and another star on a more distant, slow-moving trajectory, they write today in Astronomy & Astrophysics. The invisible companion’s mass was large enough—four times the mass of the Sun—that, if it was a star, “we would have seen it,” Rivinius says.

Though there are a lot of uncertainties, this discovery is reasonable, and expected. In the coming years astronomers will surely find more such stellar-mass black holes, with some even closer to Earth.

Blue Origin to deliver first BE-4 engines to ULA this summer

8:42 am

Capitalism in space: Development of Blue Origin’s BE-4 engine, to be used in both its New Glenn rocket as well as ULA’s new Vulcan rocket, appears to be finally reaching its conclusion with the planned delivery this summer of two operational engines to ULA.

The bulk of the article at the link is mostly a summary of stuff that had already been revealed about the development of the New Glenn rocket. The only new piece of information that I could glean was this engine delivery date. It is significant, however, because no rocket company can ever really design its rocket before it has finished building the rocket’s engines. With the BE-4 now complete, I would expect the development of both New Glenn and Vulcan to proceed with great speed.

Trump administration drafting new space agreement to supersede Outer Space Treaty

2:49 pm

The new colonial movement: According to this Reuters article, the Trump administration is presently drafting a new space agreement, which they have dubbed the “Artemis Accords,” that would allow private property ownership in space and thus supersede Outer Space Treaty’s restrictions on sovereignty.

The Artemis Accords, named after the National Aeronautics and Space Administration’s new Artemis moon program, propose “safety zones” that would surround future moon bases to prevent damage or interference from rival countries or companies operating in close proximity.

The pact also aims to provide a framework under international law for companies to own the resources they mine, the sources said.

In the coming weeks, U.S. officials plan to formally negotiate the accords with space partners such as Canada, Japan, and European countries, as well as the United Arab Emirates, opening talks with countries the Trump administration sees as having “like-minded” interests in lunar mining.

They at the moment are not including Russia or China in the discussions, since those countries have little interest in promoting private enterprise and ownership in space.

Back in 2017 I proposed in an op-ed for The Federalist that Trump do almost exactly this:

Trump should propose a new Outer Space Treaty, superseding the old, that would let nations plant their flags in space. This new treaty should establish the rules by which individual nations can claim territory and establish their law and sovereignty on other worlds or asteroids.

The American homesteading acts of the 1800s could work as a good guide. Under those laws, if an American citizen staked a claim and maintained and developed it for five years, that claim and an accompanying amount of acreage would then become theirs.

In space, Trump could propose that in order for a nation to make a territorial claim, a nation or its citizens must establish a facility. If they occupy and use it for a minimum of five years, that nation can claim it, plus a reasonable amount of territory around it, and place it under that nation’s sovereignty.

Now consider this quote from the Reuters article:

The safety zones – whose size would vary depending on the operation – would allow for coordination between space actors without technically claiming territory as sovereign, he said. “The idea is if you are going to be coming near someone’s operations, and they’ve declared safety zones around it, then you need to reach out to them in advance, consult and figure out how you can do that safely for everyone.”

In other words, the safety zones would essentially be the claimed property of the colonizers, a completely reasonable position.

It is hard to say at this moment whether the Trump administration will succeed in this tactic, of side-stepping a renegotiation of the Outer Space Treaty by working out a new agreement with other interested players. Canada for example has expressed reservations about the Trump administration’s recent public announcement encouraging private ownership of resources in space.

Regardless, that the administration now appears to be addressing the limitations of the Outer Space Treaty is very heartening news. Let us hope they can make it happen.

The eroding edge of Mars’ largest volcanic ash field

1:45 pm

Eroding yardangs at the edge of Mars' largest volcanic ash field
Click for full image.

Cool image time! In the regions between the biggest volcanoes on Mars is the Medusae Fossae Formation, a immense deposit of volcanic ash that extends across as much surface area as the nation of India. As planetary scientist Kevin Lewis of Johns Hopkins University explained to me previously,

In general, much of the [formation] seems to be in net erosion now, retaining very few craters on the surface. …One hypothesis is that this long term erosion, since it’s so enormous, is the primary source of the dust we see covering the much of the planet’s surface.

The image above, cropped and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on January 25, 2020. It shows one very small area at the very edge of the Medusae ash deposit, in a region where that deposit is clearly being eroding away by the prevailing southeast-to-northwest winds. The mesas of this ash that remain are called yardangs, their ash more tightly pressed together so that it resists erosion a bit longer than the surrounding material.

In the context map below the location of these yardangs is indicated by the white cross, right on the edge of the Medusae ash field.

California building “army” to track those infected with COVID-19

10:40 am

They’re coming for you next: The California government is now building an “army of tracers” to track those infected with COVID-19 and restrict their future movements.

Gov. Gavin Newsom addressed the concern about inadequate contact tracing on [April 22], announcing plans to train 10,000 people to help local health departments. “The good news is we believe we have the capacity to build an army of tracers,” Newsom said, although he did not say when they’d be ready to deploy.

More on that “army” and its goals here.

“As people move more, we increase the risk for people to get sick,” Sonia Angell, California Department of Public Health director and State Health Officer, said in a live stream. “If people get sick, we want to identify those individuals very early, and then make sure that all of their contacts are also identified.”

…The new contact-tracing platform the state announced today will sync up with California’s existing digital disease surveillance platform, and contact tracers can use it to check in on people’s symptoms through texts, chat, emails, and phone automation, according to Angell. Angell emphasized that the database will focus on health information and will be kept confidential. [emphasis mine]

If you believe the last two words of that quote, I have a bridge in Brooklyn I’d like to sell you.

The second link admits that for this whole plan to work, under present privacy laws “people must be willing to cooperate.” I can tell you this: If I am tested for the Wuhan flu, the very last people I will tell my results to will be these fascist thugs. They aren’t really interested in stopping the virus, which is impossible for them to do. No, what they want is to build up a database of people whom they will then have the right to oppress, by law.

And if you don’t believe me, I still have that bridge in Brooklyn for sale. Make you a good deal, too!

A failed star with cloud bands like Jupiter’s

9:32 am

The uncertainty of science: Astronomers think they have detected cloud bands similar to Jupiter’s on a brown dwarf about 6.5 light years away.

A team of astronomers has discovered that the closest known brown dwarf, Luhman 16A, shows signs of cloud bands similar to those seen on Jupiter and Saturn. This is the first time scientists have used the technique of polarimetry to determine the properties of atmospheric clouds outside of the solar system, or exoclouds.

Brown dwarfs are objects heavier than planets but lighter than stars, and typically have 13 to 80 times the mass of Jupiter. Luhman 16A is part of a binary system containing a second brown dwarf, Luhman 16B. At a distance of 6.5 light-years, it’s the third closest system to our Sun after Alpha Centauri and Barnard’s Star. Both brown dwarfs weigh about 30 times as much as Jupiter.

Despite the fact that Luhman 16A and 16B have similar masses and temperatures (about 1,900° F or 1,000° C), and presumably formed at the same time, they show markedly different weather. Luhman 16B shows no sign of stationary cloud bands, instead exhibiting evidence of more irregular, patchy clouds. Luhman 16B therefore has noticeable brightness variations as a result of its cloudy features, unlike Luhman 16A.

This conclusion is based on studying the polarized light coming from both brown dwarfs. For Luhman 16A, the result suggested bands. For Luhman 16B, the result suggested patchy, irregular clouds like on Earth.

The emphasis should be on the words “suggested” and “uncertainty.” This is good science, but the data is very sparse. We will need to actually see at these objects to really determine their weather.

New capacity limits will destroy most remaining restaurants

9:03 am

The beatings will continue until morale improves: The new capacity limits being imposed by state governments due to their panic over the Wuhan flu will likely destroy the bulk of the remaining restaurants that have managed somehow to get through the lock downs.

As some states across the country allow businesses to reopen with limited occupancies, there are still serious obstacles in the paths of restaurant owners. In those Tennessee counties that have already reopened, restaurants can’t exceed 50 percent of their maximum occupancy. Restaurants in most of Iowa will also have the option to reopen at half capacity. Those in Alaska will be limited to 25 percent capacity, and will only seat diners who make reservations in advance.

Ryan Pernice, who owns three restaurants north of Atlanta, didn’t jump with excitement when Georgia Gov. Brian Kemp released a list of 39 guidelines in advance of a push to open certain businesses — including restaurants — on April 27. Most notably for restaurant owners, the guidelines do not allow more than 10 patrons per 500 square feet in dining rooms. After Pernice closed his restaurants on March 17, leaving just one of his restaurant kitchens open for delivery, he sat down to crunch some numbers.

Even with the lights and the walk-in refrigerators turned off, running a restaurant remains an expensive endeavor. Pernice decided to continue paying for services, like pest control, that couldn’t just be ignored, as well as major costs like rent and outstanding vendor invoices. To break even and cover expenses at Table and Main, Osteria Mattone, and Coalition — his three restaurants — would cost $4,128 a day. Though he’ll take the measurements and rearrange the tables to see if reopening is feasible, Pernice can’t imagine hitting that number with only half of the seats in his restaurants occupied. “Not having run the numbers, I seriously doubt that in Table and Main, a tiny restaurant of 1,800 square feet, that I could make more doing sit-down dining than I can right now through our takeout … I think there’s very little to be gained by being the first to this party, in terms of opening the dining room again.”

In other words, under these new rules, a large percentage of the remaining restaurants will be unable to make a profit and die.

The lock downs are expected to bankrupt 20% of all restaurants, putting more than 8 million people out of work. These new rules will probably destroy, at a minimum, another 40%, mostly the smaller, independently owned businesses.

And the rules are absurd, on their face. They will not stop the spread of COVID-19, in the slightest. All they will do is destroy the lives of the people who own the restaurants.

Successfully first launch of China’s Long March 5B

8:42 am

The new colonial movement: China today successfully completed the first launch of its Long March 5B rocket, the rocket it plans to use to launch its future manned and planetary missions as well as the modules of its first space station.

The payload was the first unmanned test flight of their new upgraded manned capsule, still unnamed. It is expected that this capsule will return to Earth in the next day or so.

China’s next-generation crew carrier is also reusable for up to 10 flights, with a detachable heat shield built to handle higher-temperature returns through Earth’s atmosphere, such as those a capsule would encounter on a re-entry from a lunar mission.

The Xinhua news agency reported the primary purpose of the crew capsule test flight is to verify the ship’s re-entry technologies, such as its heat shield and recovery system. The capsule will return under parachutes and inflate airbags to cushion its landing on solid ground.

The leaders in the 2020 launch race:

7 China
6 SpaceX
6 Russia

The U.S. still leads China 10 to 7 in the national rankings.

Virginia now double-counting Wuhan flu cases

5:34 pm

Sure, let’s believe those stats! The Virginia state government this week announced that will count as a new case of the Wuhan flu for every positive test done on a patient, even if that patient had been counted previously from an earlier test.

They claim the goal is merely to get a better count of the number of tests they’ve done, but what this new policy will do is significantly increase, falsely, the total number of coronavirus cases in Virginia, which in turn will serve the corrupt and fascist goals of the governor.

That policy may serve to sharply drive up case numbers, which may in turn significantly delay the re-opening of the state. Virginia Gov. Ralph Northam has stated that the state will begin its first phase of re-opening only when state officials have logged 14 straight days of declining case numbers and hospitalizations.

The governor last week did allow elective surgeries in the state to resume, though the state’s stay-at-home order, which is set to last until June 10, is still in place.

Virginia has been hit relatively lightly by the coronavirus pandemic compared to many other states. According to Worldometers, it ranks 21st in the country for deaths per one million residents, and 20th for cases. [emphasis mine]

Northam needs some justification for extending his power-grab for as long as possible. Fudging the numbers is certainly one way to get him that justification, even if there really is no justification for the power-grab, under almost any circumstances.

First Fast Radio Burst discovered inside the Milky Way

2:22 pm

The uncertainty of science: Astronomers now think they have discovered the first Fast Radio Burst (FRB) to have occurred inside the Milky Way, only 30,000 light years away, and from this now hypothesize that the bursts come from a particular kind of neutron star called a magnetar because of its super-powerful magnetic field.

The key is that, using multiple different telescopes, they also detected X-ray emissions from the same object.

The X-ray counterpart to the SGR 1935+2154 burst was not particularly strong or unusual, said astrophysicist Sandro Mereghetti of the National Institute for Astrophysics in Italy, and research scientist with the ESA’s INTEGRAL satellite. But it could imply that there’s a lot more to FRBs than we can currently detect.

“This is a very intriguing result and supports the association between FRBs and magnetars,” Mereghetti told ScienceAlert. “The FRB identified up to now are extragalactic. They have never been detected at X/gamma rays. An X-ray burst with luminosity like that of SGR1935 would be undetectable for an extragalactic source.”

Of course, more data is needed, as well as more detections, but it appears that astronomers are beginning to hone in on the solution to the source of FBRs.

The edge of Mars’ north polar ice cap

1:55 pm

The scarp face of the Martian north polar ice cap
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on December 29, 2019 by the high resolution camera of Mars Reconnaissance Orbiter (MRO) and shows the many-layered scarp face of the Martian north polar ice cap. I have also rotated the image so that north is at the top. The overall height of this scarp is quite high, more than 3,500 feet.

There are a number of very cool features in this image. For example, note what at first look like puffs of clouds just below the contact between the bright and dark layers. I count almost two dozen, with the largest near the center. They are not cloud puffs, however, but areas scoured by past avalanches. According to Patricio Becerra at the University of Bern in Switzerland,

An image from a few years ago shows evidence for the same patches, so they likely happened a while back. When the avalanches or “block falls” occur, they scour the Basal Unit [the dark layer] and break up the exposed surface, causing a brighter/cloudier appearance of the ground than the undisturbed parts.

Avalanches on the scarps of the North Pole icecap occur in great numbers at the beginning of every Martian summer. As sunlight hits the scarp, it causes the carbon dioxide frost layer that settled on the cap during the winter to sublimate away as vapor, and like the freeze-melt cycle on Earth, this sublimation disturbs any unstable ice boulders on the scarp face.

During the early Martian summer, images from MRO routinely capture many such avalanches. Scientists think there could be hundreds to thousands every summer. In many ways, this is similar to the large pieces of ice that routinely calf off the foot of glaciers here on Earth, and that tourists take cruise ships to see in the inside passage of Alaska.

For context, the overview map below indicates with a gold cross where on the icecap’s edge this image is located. The red and pink areas indicate the vast dune fields that surround the icecap.

Experts now admit COVID-19 mortality rate much lower then predicted

11:41 am

According to Dr. Deborah Birx, the U.S. coronavirus response coordinator, the experts who initially claimed that the Wuhan flu was far more deadly than the flu were wrong, and that the death rate appears far less, closer to that of a typical flu.

“I think we underestimated very early on the number of asymptomatic cases,” Dr. Birx said. “And I think we’re really beginning to understand there are people that get infected that those symptoms are so low-grade that they don’t even know that they’re infected.”

Dr. Birx added that many of those dying from coronavirus have other diseases, such as heart disease or problems with their immune systems. “[W]e’re seeing the majority of the people that we’re losing to this disease have those other diseases that you just described,” she said. “And so, I do believe that a lot of the diseases we’re seeing in the hospital right now, yes, they may have preexisting conditions but those preexisting conditions are resulting in them having a much more serious course when they’re infected with this virus.”

In other words, the best way to defeat this virus is to get a lot of young and healthy people infected so they can develop antibodies. Those antibodies then do the job a vaccine might do, squelch the disease, and do it far faster and with almost no cost.

This article provides the evidence for Birx’s statement, outlining the five studies so far that have all confirmed the Wuhan flu death rate to be less than 1%, with four finding the rate exactly comparable to that of the ordinary flu.

I must note, with some anger, that from the very beginning, as soon as we began to collect reliable data outside of China, it was clear that this was where the data was taking us. Did any of our elected politicians or mainstream press do anything to note this fact and thus ease the panic? No. Instead, they went out of their way to pour gasoline on the fire, for their own evil and power-hungry ends.

Americans have got to stop obeying these people, or follow any of their advice. They are taking us down the road to hell.

A “gallery of snitches, busybodies, and employees who rat out their own neighbors and employers.”

11:21 am

Good: The names and addresses of 900 snitches, who reported “social-distancing violations” in Missouri on neighbors, friends, fellow employees, and their employers, have been revealed publicly, as required by the state’s Sunshine Law.

The quote in the headline was said by the man who requested the information and then posted it online for all to see.

It appears these tipsters thought they make these accusations anonymously, without any consequences. Hah! Think again. Our culture and law requires that the accused can see their accuser, or as the sixth amendment in the Bill of Rights states, “be confronted with the witnesses against him.”

Now they “fear backlash” from those they snitched against. Too bad. In fact, I applaud the guy who requested this information and posted it online.

During this entire Wuhan flu panic, there has been a lot of social pressure imposed on those that dare disagree with accepted wisdom that COVID-19 is going to kill us all and that we must take extreme measures against it, no matter what the cost. It has also been expected that one must be polite in expressing any disagreement, tiptoeing on egg shells in case you might offend them, or be accused of wanting to kill people.

Enough. It is time to stare this petty dictators in the face and tell them that they were wrong, and have caused untold harm to many. And if possible, make them feel a some pain as well for their bad behavior.

Japan tests new engine for new rocket

8:43 am

Capitalism in space: Mitsubishi has successfully tested the new engine it will use in the new rocket, the H3, that it is building for Japan’s space agency, JAXA.

JAXA reports that the engine fired for the planned duration of 240 seconds (4 minutes) at the space agency’s Tanegashima Space Center. It was the seventh hot fire of the new engine, which is powered by liquid oxygen and liquid hydrogen.

JAXA plans H-3’s first test launch by the end of the nation’s 2020 fiscal year, which began on April 1 and will end on March 31, 2021. It is not known whether work slow downs resulting from the coronavirus (COVID-19) pandemic will affect the schedule.

The two-stage H3 is intended to be a more affordable and flexible replacement for the H-IIA and H-IIB boosters now in use. The new rocket is designed to place payloads weighing 4,000 kg (8,818 lb) or more into sun-synchronous orbit at 500 km (310.7 miles) or 6,500 kg (14,330 lb) into geosynchronous transfer orbit.

I do wish JAXA or Mitsubishi would give this rocket a more interesting name. It would help their woeful marketing attempts to sell it to other customers.

Comparing the Wuhan flu with the 1968 Hong Kong flu

9:20 am

Link here.

The Hong Kong flu killed about twice as many people in the U.S. as COVID-19 has so far, and it did this for a population about a third smaller (200 million vs 328 million), meaning that its deadliness was even worse. Yet:

Nothing closed. Schools stayed open. All businesses did too. You could go to the movies. You could go to bars and restaurants. John Fund has a friend who reports having attended a Grateful Dead concert. In fact, people have no memory or awareness that the famous Woodstock concert of August 1969 – planned in January during the worse period of death – actually occurred during a deadly American flu pandemic that only peaked globally six months later. There was no thought given to the virus which, like ours today, was dangerous mainly for a non-concert-going demographic.

Stock markets didn’t crash. Congress passed no legislation. The Federal Reserve did nothing. Not a single governor acted to enforce social distancing, curve flattening (even though hundreds of thousands of people were hospitalized), or banning of crowds. No mothers were arrested for taking their kids to other homes. No surfers were arrested. No daycares were shut even though there were more infant deaths with this virus than the one we are experiencing now. There were no suicides, no unemployment, no drug overdoses.

Essentially, life went on. Except for a few people who took some precautions, mostly in connection with older and already sick individuals, everyone took little notice, recognizing that — just like COVID-19 — the Hong Kong flu was not threat to them, and that the best way to beat it was to allow the young and healthy to get it, recover, and thus develop an immunity that would limit its spread to the old and vulnerable.

The result was that the Hong Kong was a blip to society, hardly remembered today, and never a problem. Sadly the situation today is different. Because we decided to panic, we have essentially destroyed our economy and our future freedom. Behaviors that are simply absurd (wearing masks all the time and never getting closer than six feet to anyone else) are becoming socially required.

And the idea that a government can bankrupt business and harass women and children, at will, has now become acceptable.

It will be a long time before a people will ever be as free as Americans once were.

NASA buys 18 new space shuttle engines for SLS for $1.79 billion

8:09 am

NASA has awarded Aerojet Rocketdyne a $1.79 billion contract to build 18 new space shuttle R-25 engines for its still unlaunched SLS rocket.

In plain math, that equals $100 million per engine. Since SLS uses four of these engines per launch, and since that rocket is entirely expendable and will thus throw these engines away after each launch, that guarantees each SLS launch must cost no less than $400 million, about four times the price of a Falcon Heavy launch.

But wait, there’s more! Eric Berger at Ars Technica notes

NASA has previously given more than $1 billion to Aerojet to “restart” production of the space shuttle era engines and a contract for six new ones. So, according to the space agency, NASA has spent $3.5 billion for a total of 24 rocket engines. That comes to $146 million per engine. (Or 780,000 bars of Gold-Pressed Latinum, as this is a deal only the Ferengi could love.)

That means each SLS launch must cost a minimum of just under $600 million, and that’s just the price for the four engines. It doesn’t include the rocket itself, the ground systems, its upper stages, or any other component.

But wait, there’s more! Berger also reminds us that SpaceX estimates the cost to build each its Starship Raptor engines to be about $1 million, and each will be used multiple times. He also points out that the Raptor is actually more powerful than the R-25 engine.

That’s okay though. This is the federal government, run by Washington, whose goal for the few decades has been to let no project succeed, and to waste as much money as possible in the process. And if they can squelch the dreams and aspirations of everyone else as they do it, so much the better!

Sierra Nevada names its first Dream Chaser spacecraft “Tenacity”

7:52 am

Capitalism in space: Sierra Nevada yesterday announced that it is giving the name “Tenacity” to its first Dream Chaser spacecraft.

Though the press release does not say so, this decision essentially confirms the company intention to build more Dream Chaser spacecraft, once this one proves itself in flight. And I would expect those later craft will be aimed at manned flight.

SpaceShipTwo Unity makes first New Mexico glide flight

7:42 am

Capitalism in space: Virgin Galactic’s Unity suborbital spaceship successfully completed its first glide test flight from its New Mexico launch site yesterday.

They still have not set a date for their first commercial flights, so the company still claims those first flights will occur this year. I will believe it when I see it.

There does appear to be one apparent positive development for Virgin Galactic. It increasingly appears as if Blue Origin is slowly abandoning its effort to compete for suborbital tourism with its New Shepard spacecraft. Blue Origin has not said so, but the extreme slow down in test flights the last two strongly implies it. Moreover, that company’s success in garnering big government contracts, a billion from the military for its orbital New Glenn rocket and about a half billion from NASA for its proposed Blue Moon manned lunar lander, reinforces the sense that the company is shifting its focus away from suborbital space.

If so, that will clear the market for Virgin Galactic, assuming a viable market still exists with the coming of private commercial orbital spaceships like Dragon and Starliner.

NASA delays 1st SLS launch again

9:55 pm

NASA has now made official what had been expected for months, announcing a new delay of the first unmanned test flight of its SLS rocket from March 2021 to November 2021.

The article tries to put a lot of the blame for this new delay on the shut down over the Wuhan panic, but that shut down will only stop work for at most two months. The new delay however adds eight months to the schedule, showing that they probably were never going to meet that March 2021 deadline, and are using COVID-19 as a cover for the program’s continuing problems, delays, and cost overruns.

Should this unmanned flight take place in November 2021, it will have taken NASA about seventeen years and about $60 billion to get to that first flight. They say the first manned mission is scheduled in late 2022 or early 2023. If true would mean it took NASA about two decades to achieve a single manned flight since Bush Jr. proposed it.

Of course, that is making the very unlikely assumption that there will be no further delays before that first manned flight. I personally am very confident there will be.

Funding breakdown for three lunar landing contracts

3:47 pm

Capitalism in space: The contracts awarded by NASA yesterday to build manned lunar landers totaled almost a billion dollars, distributed as follows:

  • Blue Origin: $579 million
  • Dynetics: $253 million
  • SpaceX: $135 million

That Blue Origin got the biggest amount might have to do with the bid’s subcontractors, Lockheed Martin and Northrop Grumman. This gives these traditional big space partners, who normally rely on these kinds of government contracts and have little ability to make money outside them, some financing. This will also please their political backers in Congress.

For SpaceX, this is the first time they have taken any government money in connection with Starship. It also appears that NASA is going to stay back and generally let SpaceX develop it without undue interference.

Scientists better constrain time frame of Mars’ active dynamo

12:33 pm

Using data from the MAVEN orbiter, scientists have now constrained the time frame when Mars’ dynamo was active and producing a global magnetic field, between 3.7 and 4.5 billion years ago.

Magnetism in certain rocks on Mars’ surface indicate that the Martian dynamo was active between 4.3 and 4.2 billion years ago, but the absence of magnetism over three large basins – Hellas, Argyre, and Isidis – that formed 3.9 billion years ago has led most scientists to believe the dynamo was inactive by that time.

Mittelholz’s team analyzed new data from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) orbiter and found clear evidence of a magnetic field coming from the Lucus Planum lava flow that formed about 3.7 billion years ago – much later than at other areas studied.

There is of course a lot of uncertainty here.
