Mini-volcanoes (mud or lava?) near Zhurong’s Mars landing site

2:11 pm

Mosaic of features near Zhurong's planned landing site on Mars
Click here, here, and here for full images.

Cool image time! Though we still do not know exactly where the Chinese Mars rover Zhurong landed on Mars, we have a rough idea based on the latitude and longitude numbers leaked to the Chinese press in October 2020 and were apparently confirmed by photos taken by the Tianwen-1 orbiter soon after reaching Mars. We also know Zhurong’s engineers wanted to land in the northern lowland plains dubbed Utopia Planitia, a region that is relatively flat and thus makes a safe landing spot for their first attempt to reach the surface of Mars.

The mosaic to the right, rotated and reduced to post here, is made from three context camera images taken by Mars Reconnaissance Orbiter (MRO). The white cross on the right edge is essentially Zhurong’s leaked landing spot. The red box indicates the area covered by one of only two photos that China has released that were taken by its Tianwen-1 orbiter.

The white box in the upper left shows the area covered by today’s cool image, shown below.

Today’s blacklisted American: College volley ball player blackballed for her opinions

12:29 pm

The Bill of Rights cancelled at Amazon
Doesn’t exist at the University of Oklahoma.

They’re coming for you next: A college volley ball player at the University of Oklahoma, Kylee McLaughlin, was blackballed from her team because she refused to endorse the agenda of Black Lives Matter and voiced her own conservatives opinions during a team discussion after viewing a left-wing political film about American prisons.

When she also expressed some of her conservative opinions on social media, her coach demanded she delete the post immediately and call all the team’s coaches and players to apologize.

The legal document says: ‘Although (McLaughlin) supports equality, social justice, and finds racism despicable, she disagreed with the WOKE culture and critical race theory advocated and practiced by two of her coaches who are the Defendants in this action.’

She said coaches and administrators later told her she did not fit in with the culture and gave her three options to continue at the university without playing time. She was given the choice of transferring, continuing on scholarship as a non athletic student or taking a redshirt year, keeping her scholarship and practice separately from the rest of the team. During the redshirt year, she was made to carry out more than 10 hours of online diversity and inclusion training, she said.

She didn’t say anything racist, she merely disagreed with the leftist agenda of the movie they saw. But since “one black teammate” was offended and determined without challenge that she was racist, the coaches decided they had to blackball her.

More evidence the COVID-19 panic was just that: an unwarranted panic

12:04 pm

The Scream by Edvard Munch
The Scream by Edvard Munch, the absolute wrong response
to any emergency, and sadly the very response Americans adopted
against COVID-19.

Three more stories in the past few weeks have proven once again what I and many others saw unequivocally more than a year ago: The panicky response to COVID was unwarranted and not based on the actual facts on the ground but on manipulated and unproven assumptions.

Those assumptions were touted for purely political reasons. Worse, too many Americans meekly accepted those assumptions without any of the kind of mature skepticism that is required of adult citizens in a democratic republic. The result: Our rights were violated and false and corrupt politicians gained power, power they eagerly abused.

First, officials in Alameda County in California revealed on June 4th that they have reduced the number of COVID deaths in that county for the past year by about 25%, from 1,634 to 1,223.

“There are definitely people who died from reasons that were clearly not caused by COVID,”said Neetu Balram, a spokesperson for the Alameda County Public Health Department. Balram couldn’t give specifics about the true cause of death for the 411 people removed from the COVID-19 data, but she said the cases were identified after reviewing codes entered by county coroners into CalREDIE, the state’s database for disease reporting and surveillance.

None of this is a surprise to anyone who was open-minded enough to pay attention. The federal government provided hospitals and doctors a bonus for claiming as many deaths as possible as caused by COVID. They thus inflated the numbers grossly. Moreover, encouraging a panic in 2020 over the Wuhan flu served the political ends of the Democratic Party (to which almost all health officials belong) because it then justified the illegal easing of election laws so that Democrats could commit election fraud in November with ease.

Thus, doctors had both financial and political incentives to inflate the COVID numbers, which apparently they did with glee.

Two research papers published in mid-May added further weight to these conclusions:

Astra buys space tug company that builds electric engines

9:10 am

Capitalism in space: The smallsat rocket company Astra announced today that it has brought Apollo Fusion, a space tug company that builds electric engines designed to move satellites from orbit to orbit.

Astra is purchasing Apollo Fusion for $30 million in stock and $20 million in cash in a deal announced June 7. The deal includes an additional $95 million in earn-out incentives if Apollo Fusion reaches certain technical and revenue milestones. Astra will incorporate Apollo Fusion’s Apollo Constellation Engine electric propulsion systems in satellite buses the company is developing to provide an integrated solution to customers.

Astra however has still not completed its first orbital flight. Its last test launch, in December 2020, almost reached orbit but did not. Company officials are now saying the next launch will be this summer, followed by monthly launches in the fall.

Bezos to fly on first manned New Shepard suborbital flight in July

8:52 am

Capitalism in space: Jeff Bezos announced today that he and his brother Mark will be passengers on the first manned commercial New Shepard suborbital flight, now scheduled to launch on July 20th.

“I want to go on this flight because it’s a thing I wanted to do all my life. It’s an adventure. It’s a big deal for me,” Bezos says in the brief video.

In that video, Bezos asks his younger brother Mark, to accompany him on the flight. “I think it would be meaning to have my brother there,” he said.

Mark Bezos accepted. “I wasn’t even expecting him to say that he was going to be on the first flight,” he said in the video. “And when he asked me to go along, I was just awe-struck.”

Right now the high bid in the auction for the other passenger seat remains stuck at $2.4 million. The bidding ends on June 12 with a live auction instead of an online one, but it appears that whoever bid that amount has no competitors and will be the passenger.

As for Bezos’ flight, his announcement means he will beat out Richard Branson for this honor. Bezos’ victory is especially embarrassing to Branson, who had been promising everyone that he would be the first suborbital passenger on his Virgin Galactic SpaceShipTwo suborbital spacecraft for almost twenty years. Those promises were bunkum. Bezos meanwhile made no such promises, and will deliver.

If you had to choose between these two car salesmen, who would you pick?

I however would choose neither. These suborbital car salesmen are fighting over the honors to launch what is equivalent to a rowboat. Elon Musk’s SpaceX is meanwhile building the equivalent of an ocean liner (Starshp) even as it is about to launch the equivalent of the first passenger steam ship (Falcon 9 with paying civilian passengers). I pick Musk.

SpaceX launches commercial radio satellite with reused Falcon 9

9:58 pm

Capitalism in space: SpaceX tonight successfully launched a Sirius-XM commercial radio satellite using its Falcon 9 rocket.

The first stage, making its third flight, successfully landed on the drone ship in the Atlantic. Note too that this launch took place only three days after SpaceX’s previous launch. Watching it take place, I was struck by how completely routine everything seemed. While rocketry will never be easy, SpaceX now makes it look so, and they do so because, unlike all other rocket companies, they did not stop upgrading and improving their rocket once it became somewhat reliable. Instead, they focused on making it more reliable than any rocket ever by making it reusable. That effort has now paid off, giving them a rocket that works like clockwork, practically every time.

The leaders in the 2021 launch race:

18 SpaceX
15 China
8 Russia
2 Rocket Lab
2 ULA

The U.S. now leads China 24 to 15 in the national rankings.

Today’s blacklisted American: Doctors fired and blackballed for calling for race-neutral policies in medicine

1:32 pm

Lysenko with Stalin
Trofim Lysenko preaching to Stalin. His policies destroyed
Soviet plant research, persecuted anyone who disagreed
with him, and caused famines that killed millions. And they are
all policies now being adopted by the American medical field.

Persecution is now cool! Last year, the University of Pittsburgh fired cardiologist Norman Wang because he wrote and published a peer-reviewed paper calling for race-neutral policies in medicine.

In addition, he was publicly denounced by the American Heart Association (AHA) and the journal retracted his paper, even though no one could cite any errors in his work.

As the criticism mounted, Wang was removed from his position as the director of a fellowship program in clinical cardiac electrophysiology at University of Pittsburgh Medical Center and was prohibited from making any contact with students. His boss reportedly told him that his classroom was “inherently unsafe” due to the views he expressed.

Unsafe, eh? Can’t have those students hear any opinions or facts that might contradict the modern “woke” narrative!

Wang is suing both the AHA and the University of Pittsburgh for defamation and violating his first amendment rights. Whether he wins or not remains quite unknown, especially considering the increasingly intolerant nature of today’s society.

The article at the link however goes far beyond simply telling Wang’s story. First, it describes the cases of two other doctors who were forced to resign for similar reasons: they questioned the modern obsession with race and suggested that things would be far better if “race was taken out of the conversation.” The mob immediately rose up against both, and their medical organization, the American Medical Association (AMA), then moved to get them fired or removed.

The article then however goes even farther, outlining how this evil oppressive blacklisting culture is beginning to have a much wider and very negative impact on the practice of medicine and the treatment of patients.

Curiosity's future travels
Click for full image.

Cool image time! In the coming weeks and months the view from Curiosity is going to give us the most spectacular views of another world since the Apollo astronauts walked on the Moon.

In today’s download of new images from the Mars rover Curiosity was the photo above, reduced to post here. Taken by rover’s right navigation camera, it looks west directly in line with Curiosity’s future travels, and shows that it is now finally entering mountain country.

The overview map below provides the context.

New investment capital pours into commercial space

10:29 am

Launcher's E2 engine
Launcher’s 3D printed E2 engine, claimed by the company
to be the highest performance engine for small rockets.

Capitalism in space: Three stories today underlined superbly the robust and steadily growing state of the commercial space industry. Moreover, these stories suggest that this growth will be permanent with almost no limit to its possibilities.

To begin, we have the public appearance of another startup smallsat rocket company, dubbed Launcher.

Small launch vehicle developer Launcher has raised $11.7 million in a Series A funding round, which the company says puts it on a path to reaching orbit with a fraction of the total investment of other launch startups. Launcher said June 2 that the Series A round was co-led by Boost.VC and the company’s founder, Max Haot, both of whom earlier provided seed funding to the startup. Haot invested $5 million using proceeds of a camera company, Mevo.com, that he sold earlier this year to Logitech. Other existing and new investors also participated in the round, which Haot told SpaceNews was oversubscribed.

…Launcher is working on a small launch vehicle called Launcher Light, intended to be similar in performance to Rocket Lab’s Electron, which can place up to 300 kilograms into low Earth orbit. Launcher Light is a smaller version of Rocket-1, the company’s original vehicle, which Haot said in March should speed up development since it will require fewer engines.

The company hopes to launch by ’24, and is also planning another fund-raising round next year to raise an additional $40 million.

Considering the large number of new rocket companies raising capital, who knows if this company will make it. Certainly some will grab market share and survive, but more likely in the coming decade there will be a shake-out where many will either consolidate or disappear, similar to what happened in the early days of the automobile industry.

That so many similar new rocket companies are attracting so many investors however shows that people with money are now convinced that space is the place, and the future there is very bright for profit. And what lends weight to this sentiment are the other two stories today, both of which involve new space startups that are not rocket companies but the kind of ground facilities required by the satellites those rockets launch.

Third set of new results from Parker released

9:32 am

The scientists using the Parker Solar Probe on June 2nd released their third set of new results as part of a special issue of the journal Astronomy & Astrophysics.

The latest articles include data analysis, theory, and modeling. Among the major topics covered are magnetic switchbacks first discovered by Parker Solar Probe, the role of waves in heating solar plasma, solar angular momentum, the near-Sun dust environment, and the diversity of small energetic-particle events.

The most interesting paper I think is the one describing data that lends strong weight to the theory, proposed in 1929 by astronomer Henry Norris Russell, that a dust-free zone exists close to the Sun and all stars. From the abstract:

The observed brightness decrease in the axis of symmetry is interpreted as the signature of the existence of a dust density depletion zone between about 19 [solar radii] and 3 [solar radii] which at the inner limit of WISPR’s field of view of 7.65 [solar radii] has a dust density that is ~5% lower than the density at 19 [solar radii], instead of the expected density which is three times if no depletion zone exists.

In plain English, the data shows that from about 1.3 million to 8.2 million miles from the Sun Parker found far less dust than predicted by other models. As the probe continues to lower its orbit and get closer to the Sun with each fly-by these numbers will be better refined, and are likely to in the end prove Russell’s hypothesis.
