Ralph Vaughn William – 5th Symphony
An evening pause: Performed live in 2016 by the Frankfort Radio Symphony Orchestra.
This is long for an evening pause, but William’s gentle, mild British tones I think make a great way to start the weekend. Use it to unwind from your daily workweek craziness.
Hat tip Dan Morris.
Glaciers in the Martian south latitudes
Click for full image.
Most of the glacier cool images I have posted in the past few years from the high resolution camera on Mars Reconnaissance Orbiter (MRO) have shown the obvious glacial features found in the northern hemisphere in that 2,000 mile long strip of chaos terrain at about 40 degrees latitude I dub “Glacier Country.”
Today’s glacier image to the right, cropped and reduced to post here, takes us instead to the southern hemisphere, into Hellas Basin, the death valley of Mars. The picture was taken on April 8, 2021, and in the full picture gives us a myriad of examples of glacial features. The section featured to the right focuses in on what appears to be an ice covered south facing slope, which in the southern hemisphere will get the least sunlight.
Think of the last bits of snow that refuse to melt after a big blizzard. They are always found in shadowed areas, which in the southern hemisphere would be this south-facing slope.
The overview map below shows how this location, marked by the small white rectangle, is inside Hellas Basin, at a low altitude comparable to the northern lowland plains. The feature is also a comparable latitude, 43 degrees south, to the glacier country of the north.

Today’s blacklisted American: Garden hoes banned by Facebook!
According to Facebook, a garden hoe apparently represents evil
and the worst of white supremacy.
Today’s blacklisted American, garden hoes, is meant more to illustrate the utter brainlessness of the blacklist culture, and why every intelligent American should refuse to bow to it in any way.
It appears that Facebook has been repeatedly flagging and then blocking posts on a gardening group because those gardeners periodically make reference to the gardening tool called a “hoe.”
A group called WNY Gardeners has been repeatedly flagged by the social network for “violating community standards,” when its more than 7,500 members discussed the long-handled bladed implement, which is spelled with an “e,” unlike the offensive term.
When one member commented “Push pull hoe!” on a post about preferred weeding tools, Facebook sent a notification that read, “We reviewed this comment and found it goes against our standards for harassment and bullying,” a moderator said.
“And so I contacted Facebook, which was useless. How do you do that?,” Elizabeth Licata said. “You know, I said this is a gardening group, a hoe is gardening tool.”
Nor has this been Facebook’s only “hoe” error. It had also been routinely flagging posts that referred to the English seaside community of Plymouth Hoe.
Facebook of course never responded to gardening group when they complained, as is usual for these inhumane big tech companies. However, when this story began appearing in the press, it told the AP that it was sorry about it, had corrected the algorithms that had caused the problems, and had assigned a real human to monitor the gardening group to make sure it is not censored for ordinary gardening discussions.
Hah! That didn’t work. The gardeners soon found themselves censored for writing about the various techniques they use for battling the Japanese beetle, a destructive pest to “flowers, trees and shrubs, fruits and vegetables, field crops and turf.” When on commenter suggested that gardeners should “Kill them all. Drown them in soapy water,” and “Japanese beetles are jerks,” the posts were blocked by Facebook.
It seems Facebook employees really don’t know how to read. Instead, they work eagerly to silence anyone for any statement they think should be silenced, without thought.
Throwing away the Kerwood Derby
All this reminds me of the short clip below from the early 1960s cartoon show, Rocky & Bullwinkle.

News flash! Union lobbyists wants to influence Biden against non-union SpaceX
In the past two days probably a dozen of my readers have sent me a link to this story at the Washington Examiner,
The Anti-SpaceX lobbying campaign casts new light on Elon Musk’s Biden beef.
The story reveals some private emails between a union lobbyist and a vice president at ULA, outlining their mutual effort to discredit Elon Musk and SpaceX because of its long term success in preventing its workforce from unionizing.
Everyone who has sent me this story somehow thinks it reveals a major breaking story.
I think this story is a tempest in a teapot. It reveals nothing newsworthy. All it shows is that a union lobbyist is trying to influence the Biden administration against SpaceX, a decidedly non-union company. Why should these actions surprise anyone? Unions always go after non-union companies, and they often do it by exerting their political clout.
Nor should be we surprised that one of SpaceX’s biggest competitors is partnering with the union in this effort. There is nothing newsworthy about this. Competitors compete, and that competition can sometimes be quite cut throat.
Furthermore, nothing in these emails appears illegal. The lobbyist’s claims against SpaceX are spurious and shallow, but so what? Unions have the right to lobby politicians, and they have the freedom to make whatever arguments they want, even if those arguments are silly or false.
Finally, to think it is a news story that Biden might be receptive to union lobbyists is kind of silly. Biden is a modern Democrat. In almost all matters he is going to genuflect to the unions. I don’t need to read the private emails of a union lobbyist to find this out.
However, the evidence in the past ten months shows that this lobbying effort has so far been incredibly ineffective. While I certainly do not trust the Democrats running the Biden administration, and fully expect them to take actions eventually to squelch private enterprise, this White House’s actions regarding space has so far generally continued the capitalist policies begun during the Trump administration. Note too that these are the same policies first begun at the end of the Bush Jr. administration, and encouraged strongly throughout the Obama administration. It certainly appears that — in space at least — the Democrats are as much for capitalism as the Republicans.
And these emails have apparently done nothing to change that. Thus, there is no news here.

Northrop Grumman says six customers have bought missions using its upgraded orbital repair robot
Capitalism in space:A Northrop Grumman official has revealed that it already has six customers willing to buy missions using its upgraded orbital repair robot to fix orbiting satellites that are presently defunct due to lack of fuel.
Unlike the company’s first robotic repair satellites, dubbed Mission Extension Vehicles (MEV), the Mission Robotic Vehicle (MRV) for these new contracts will not dock directly to the satellite, but use a robot arm to attach an extension pod to each.
The primary commercial mission of the MRV is to install small propulsion devices known as mission extension pods. One of these units is inserted in the back of a client satellite propulsion system, adding six years of life to most geostationary satellites, he said.
The six customers have signed term sheets for seven mission extension pods, Anderson said. Once contracts are firmed up the company will be able to disclose their names.
The first MRV launch in 2024 will carry three pods. “With these six customers, the MRV manifest is currently filled through mid-2026,” he said. The MRV is expected to have a 10-year service life.
This MRV system is far more cost effective than the MEV, since the latter can only repair one satellite, while the former can fix several with a single launch.
Both Northrop Grumman and Astroscale (see my previous post) are demonstrating the emergence of a new cottage satellite industry, the repair of old satellites and the removal of space junk, all for profit.

Rocket Lab wins contract to launch space junk removal satellite
Capitalism in space: Rocket Lab announced this week that it has won a launch contract from the Japanese-based company Astroscale to launch its first attempt to rendezvous with a piece of space junk — an abandoned upper stage from a Japanese launch — in order to grab and de-orbit it.
Rocket Lab announced Sept. 21 that it won a contract from Astroscale for the launch of its Active Debris Removal by Astroscale-Japan (ADRAS-J) spacecraft. A Rocket Lab Electron will launch ADRAS-J from its Launch Complex 1 in New Zealand in 2023.
ADRAS-J will rendezvous with and inspect an upper stage left in orbit by a Japanese launch. The Japanese space agency JAXA awarded Tokyo-based Astroscale a contract in 2020 for the mission as part of its two-phase Commercial Removal of Debris Demonstration project.
The first phase of this demonstration project involved Astroscale’s current test satellite, which is presently testing capture techniques of space junk using magnets.
It appears Rocket Lab got the contract because it can place this smallsat in the precise orbit it needs, and can do it for far less than any other launch company in operation at present.

InSight detects the three more large quakes on Mars, the most powerful measured so far
In the past month InSight’s seismometer has detected the three most powerful earthquakes so far measured on Mars, with one located in a region where no quakes had as yet been seen.
InSight spotted 4.2- and 4.1-magnitude temblors on Aug. 25, then picked up another roughly 4.2-magnitude quake on Sept. 18 that lasted for nearly 90 minutes, NASA officials announced on Wednesday (Sept. 22).
The previous record holder, which InSight measured in 2019, clocked in at magnitude 3.7 — about five times less powerful than a 4.2-magnitude quake.
At this time scientists have only been able to roughly pinpoint the location of the two August quakes, with the 4.1 quake occurring about 575 miles away, putting it in the volcanic plains where InSight sits and closer than the location of most of the previous large quakes near the long surface fissures dubbed Cerberus Fossae 1,000 miles away.
The August 4.2 quake’s is even more interesting, as its location is the farthest away of any so far detected, at an estimated distance of 5,280 miles away. The scientists presently suspect but have not yet confirmed that it may be located in the western end of Valles Marineris, Mars’ largest canyon.
The lander itself continues to fight a loss of power due to the amount of dust on its solar panels, forcing the science team to shut down practically all its other instruments so that the seismometer could continue operating.

A clue to the Martian history of volcanic eruptions
Click for full image.
Anyone who has taken even a single glance at a map of Mars cannot help but recognize that the red planet was once engulfed with repeated gigantic volcanic eruptions able to build numerous volcanoes larger than anything seen anywhere else in the solar system.
The cool image to the right, rotated, cropped, and enlarged to post here, provides a clue into those past eruptions, now thought to have been active for more than several billion years, with the most recent large activity ending several tens of millions of years ago. The photo was taken on May 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows just one tiny portion of the vast Medusae Fossae Formation, the largest thick volcanic ash deposit on Mars, about the size of India and what scientists think is the source of most of the planet’s dust.
What makes this picture interesting are the dark layers in the lower hollows. They indicate that this deposit was placed down in multiple eruptions, some of which produced material that appears dark blue in MRO images, and suggest that eruption was different than previous and subsequent eruptions.
The white cross on the overview map below notes the location of this picture in the Medusae Fossae Formation.

Today’s blacklisted Americans: Republicans blacklisted 53 to 1 over Democrats on social media
Republicans: Routinely silenced by Twitter, Facebook, and YouTube.
Blacklists are back and the Democrats have got ’em: According to a review of the actions of the big social media companies against politicians, the Media Research Center has found that Republicans are censored at a rate 53 times more than Democrats on social media.
The attacks on Facebook, Twitter, YouTube, Google, Instagram, and others have been against both standing Republican members of Congress as well as Republican candidates running for office, with further evidence showing that Facebook very specifically has been favoring Democratic incumbents.
Nor have the top managers and owners of these social media companies been able to counter this data.

Fired flight director accuses Virgin Galactic of lying about problems on July suborbital flight
A former Virgin Galactic flight director, who was relieved of his duties just before the company’s July suborbital flight that carried Richard Branson and then fired shortly thereafter, has accused Virgin Galactic of misleading the public in its statements about the problems that occurred during that flight.
Virgin Galactic has claimed that the high winds forced the spacecraft away from its planned flight path.
Mark Stucky, who Virgin Galactic fired eight days after Branson’s flight, said his former employer put out an inaccurate statement about why VSS Unity flew unauthorized into Class A airspace for 1 minute 41 seconds during its descent. Class A airspace is primarily used by airlines, cargo operators and higher performance aircraft.
“The most misleading statement today was @virgingalactic’s,” Stucky tweeted. “The facts are the pilots failed to trim to achieve the proper pitch rate, the winds were well within limits, they did nothing of substance to address the trajectory error, & entered Class A airspace without authorization.”
There is no way to know if Stucky’s accusation is correct. We might be seeing a bit of personal anger on his part considering his firing. At the same time, the FAA’s statement about this issue made no mention of winds, which suggests the Virgin Galactic statement might not be true.
Regardless, Virgin Galactic’s track record in matters of safety has not been stellar. The company needs to quickly resolve these issues or they will become a lingering sore that will damage sales for future suborbital flights.

Wuhan panic continues to shut down India’s space agency
While most private companies and many nations, such as China and Russia, have been launching continuously since the advent of the coronavirus panic last year, India’s space agency ISRO continues to be shut down, completing few launches with a story today suggesting that the three remaining planned launches for 2021 will likely be delayed until next year.
There have only been two launches this year – the purely commercial PSLV C-51 launch in February carrying Brazil’s earth observation satellite Amazonia-1 and the GSLV-F10 mission in August carrying an Indian earth observation satellite EOS-03 that failed.
To be sure, the space agency has plans for three more missions before the end of the year, including the first development flight of the SSLV [Small Satellite Launch Vehicle]. The other two will use India’s workhorse PSLV to launch two earth observation satellites EOS-04 and EOS-06.
“The three planned missions appear unlikely this year,” a senior scientist at the agency said on condition of anonymity.
Worse, before the year began ISRO had reduced its targeted number of missions for ’21 from 16 to 5.
The article makes believe the epidemic has shut down other programs, such as Artemis, in the same way, but that is false. NASA’s Artemis program might have lost a few months in ’20 due to the agency’s panic over COVID, but since then it has been moving as fast as it can, considering the cumbersome nature of its engineering. Even Rocket Lab, which has been badly hampered by New Zealand draconian Wuhan rules, has managed to launch eleven times since January 2020, compared to the four launches attempted by India during that same time.
Whatever has caused the shut down at ISRO, it really hasn’t been the epidemic. Something about the agency’s management and its bureaucratic culture has prevented them from resuming flights. And as they remained stalled, the private commercial companies in the U.S. and China are grabbing their customers.

The Romantics – One in a million
Today’s blacklisted American: Weatherman fired after 33 years for not getting COVID vaccine
Weatherman Karl Bohnak, now a non-person.
Persecution is now cool! Karl Bohnak, who had been a weatherman for the Michigan television station WLUC for 33 years, was fired last week because he refused to get the COVID vaccine shot as now mandated by the station.
Bohnak announced his firing in an essay on his Facebook page [requires Facebook login]. I have posted the full text at the end of this essay, also posted here, to illustrate the rational, thoughtful nature of his decision. You might disagree with him, and think he should get vaccinated, but he outlines in clear detail his valid reasons for not doing so.
His essay also raises the very valid constitutional and ethically reasons for resisting the mandate of this company.
The abrogation of our liberty and freedom under the guise of a pandemic is very disturbing to me. Hopefully, whether you lean right or left, you are concerned about what has occurred the last year-and-a-half. I just wanted to go about my business, “live and let live”, and keep my mouth shut. But this act by the federal government through corporate America has brought me to a crossroads. Our way of life, our freedom and liberty, is collapsing before our eyes.
Sadly, Bohnak is not alone in this. Thousands of people across America are willingly losing their jobs because they will not submit to this dictatorial and entirely unconstitutional vaccine mandate. As the left has loudly proclaimed for decades, these Americans are declaring, “Our bodies, our choice!”
From the beginning, the data said that the lethality of COVID would merely be a variation of the flu. » Read more

Cool image time! The photo to the right, cropped, reduced, and enhanced to post here, was taken on September 21, 2021 by Curiosity’s high resolution mast camera, and shows the top of that spectacular rock outcrop about 200 feet to the west of where the rover presently sits. The top image, from my September 16, 2021 post, “Curiosity: Into the Mountains!”, indicates the location of the photo with the black rectangle. The red dotted line indicates the rover’s future planned route.
I estimate the whole outcrop is about 100 feet high, which means the cliff section seen in the photo to the right is probably about 30 feet high. It would make a great challenge for any number of rock climbers I know.
What makes this image especially striking are the overhanging rocks at the peak’s top. In the Martian gravity, about one third that of Earth’s, it is possible for much more delicate rock shapes to remain structurally stable, and the sharp jagged boulders hanging out at the top of this cliff demonstrate that in a quite breath-taking way. On Earth such delicate rocks would likely have quickly fallen.
The Curiosity science team is obviously most interested in the massive layers revealed by this cliff. I am also sure they are also as enthralled by the scenery as I am.

Cool image time! The photo to the right, cropped, reduced, and enhanced to post here, was taken on September 21, 2021 by Curiosity’s high resolution mast camera, and shows the top of that spectacular rock outcrop about 200 feet to the west of where the rover presently sits. The top image, from my September 16, 2021 post, “Curiosity: Into the Mountains!”, indicates the location of the photo with the black rectangle. The red dotted line indicates the rover’s future planned route.

Firefly selling its rocket engines to Astra
Capitalism in space: It now appears that Firefly’s effort to diversify its rocket business by selling its Reaver rocket engine to other companies has resulted in it selling that engines to its competitor Astra, for possible use either in that company’s smallsat rocket or in an new redesigned rocket not yet revealed.
Under the [$30 million] deal, which closed earlier this year, Firefly will send up to 50 of its Reaver rocket engines to Astra’s rocket factory in Alameda, California, where a development engine was already delivered in late spring for roughly half a million dollars, according to an internal Firefly document viewed by The Verge and a person briefed on the agreement. Astra engineers have been picking apart the engine for detailed inspection, said a person familiar with the terms, who, like others involved in the deal, declined to speak on the record because of a strict non-disclosure agreement.
Apparently, the contract includes clauses that forbid Astra from using the engine in circumstances that directly compete with Firefly’s Alpha rocket.
The article also suggests that the contract will allow Astra to manufacture the engine itself, thus keeping its operations in-house and not dependent on outside contractors.
The deal suggests two things. First, it shows the growing strength of Firefly. It is not only going to make money launching satellites, it will also do so selling engines to other companies. Second, the deal suggests Astra has issues with its own rocket engine, and needs something better quickly to survive.

NASA awards Aerojet Rocketdyne contract to build 20 Orion main engines
NASA announced yesterday that it has awarded Aerojet Rocketdyne the contract to build twenty Orion main engines for capsules on missions running through 2032, with the first to be used on the seventh Artemis launch..
This engine is the one that Orion will use to enter and leave lunar orbit.
Based on the pace that NASA expects to launch SLS, once per year, I expect the last engine in this contract will fly in 2048, not 2032, since it will take about 27 years to put that many Orions into space after SLS’s first launch, expected sometime in the next five months.
In other words, this is a contract to keep the jobs at Aerojet Rocketdyne in existence for the next three decades, even if that company’s engineers build little and accomplish less. Nice welfare work I must say.

Galaxies in the early universe don’t fit the theories
The uncertainty of science: New data from both the ALMA telescope in Chile and the Hubble Space Telescope about six massive galaxies in the early universe suggest that there are problems and gaps in the presently accepted theories about the universe’s formation.
Early massive galaxies—those that formed in the three billion years following the Big Bang should have contained large amounts of cold hydrogen gas, the fuel required to make stars. But scientists observing the early Universe with the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope have spotted something strange: half a dozen early massive galaxies that ran out of fuel. The results of the research are published today in Nature.
Known as “quenched” galaxies—or galaxies that have shut down star formation—the six galaxies selected for observation from the REsolving QUIEscent Magnified galaxies at high redshift. or the REQUIEM survey, are inconsistent with what astronomers expect of the early Universe.
It was expected that the early universe would have lots of that cold hydrogen for making stars. For some galaxies to lack that gas is inexplicable, and raises questions about the assumptions inherent in the theory of the Big Bang. It doesn’t disprove it, it simply makes it harder to fit the facts to the theory, suggesting — as is always the case — that the reality is far more complicated than the theories of scientists.

Starliner unmanned demo flight likely delayed until ’22
Capitalism in space: The second Starliner unmanned demo flight, repeatedly delayed throughout ’21 due to scheduling and technical problems, is now likely to be delayed until next year.
Apparently, Boeing engineers have been unable to figure out why 13 of 64 valves on Starliner failed to function properly just hours before the last planned launch, causing the launch to be scrubbed.
The quality control systems at Boeing during this entire program have not shined. The capsule is now years behind schedule, and has been dogged by design and construction flaws — from software to parachutes to valves — that in the 21st century should not be problems any longer in building a manned spacecraft.
Like SpaceX and its Dragon capsule, Boeing owns Starliner and will be able to offer private citizens and companies flights on it once it is operational. These failures, however, will not be good for that future business. They make this spacecraft a far less appealing product when compared to the high quality of the engineering at SpaceX. Why would anyone risk their life on Starliner when they can buy a ticket on the apparently much more reliable Dragon?
In other words, Boeing has been doing terrible harm to its brand name with these problems. It needs to get them fixed, and fast.

NASA reorganizes bureaucracy of manned programs
Moving those deck chairs! NASA yesterday announced that it is reorganizing the bureaucracy of its manned programs, splitting the Artemis program out from the commercial program.
The space agency announced today (Sept. 21) that it’s splitting the current Human Exploration and Operations Mission Directorate (HEOMD) into two new entities: the Exploration Systems Development Mission Directorate (ESDMD) and Space Operations Mission Directorate (SOMD).
…ESDMD will be responsible for the development of systems and technology critical for NASA’s Artemis program, which aims to land astronauts on the moon in the next few years and establish a sustainable human presence on and around Earth’s nearest neighbor by the end of the 2020s. ESDMD will also map out NASA’s broader “Moon to Mars” exploration strategy, of which Artemis is an integral part, agency officials said. (NASA aims to land humans on Mars in the 2030s, by leveraging the skills and techniques learned during the Artemis moon effort.)
SOMD, meanwhile, will be in charge of crewed launches and ongoing human spaceflight operations, including activities on the International Space Station and the commercialization of low Earth orbit, a NASA priority over the coming years. SOMD will also be responsible for crewed operations on and around the moon once they get up and running.
Kathy Lueders, who had been promoted from just running the commercial crew program to run all of manned space back in 2020, will once again run just the commercial side. The Artemis side will be run by another long time NASA administrator, Jim Free.
As I noted in 2020, these kinds of reorganizations at NASA happen periodically, and generally accomplish little except to allow NASA’s top managers to make believe they are doing something. In this case the split I think is intended to prevent Artemis from being completely taken over by commercial space, thus giving some bureaucratic clout to SLS and the factions at NASA that favor government control, with NASA designing and building everything rather than simply being a customer. If so, the decision is a bad one for Artemis. It means the Biden administration and those factions want to once again take over the design and construction of the entire Artemis program. Since NASA’s track record in this area has been abysmal for decades, it is unlikely this shift will change anything for the better.
This reorganization also suggests that the Biden administration has had second thoughts about the private and commercial approach as recommended in my policy paper, Capitalism in space and adopted by the Trump administration. If so, the consequences for the new emerging private space industry will not be good. They shall increasingly find the government more eager to micromanage their designs and concepts, rather than allowing the private sector the freedom to create things on its own.
The one silver lining to this change is that by creating these two divisions, NASA will be highlighting the competition between them. As commercial space increasingly succeeds, leaving the cumbersome Artemis program far behind, the split will illustrate clearly to the entire world that a government-built program is not the way to go.

How to discover interesting things on Mars
Today’s cool image will do something a little different. We are going to begin in orbit, and by step-by-step zooming in we will hopefully illustrate the great challenge of finding cool geological features on the surface of Mars.
The first image to the right is an overview map of the Valles Marineris region. To its east, centered at the white dot, is a vast region of chaos terrain, endless small buttes and mesas and criss-crossing canyons. Travel in this region will always be difficult, and will likely always require some form of helicopter to get from point to point.
What is hidden in that terrain? Well, to find out you need to take a global survey from orbit with a good enough resolution to reveal some details. Below is a mosaic made from two wide angle context camera pictures taken by Mars Reconnaissance Orbiter (MRO).
For full images go here and here.
This mosaic, rotated, cropped, and reduced to post here, only captures a small section of the long north-south strips taken by MRO. The orbiter has taken tens of thousands of these strips, in its effort to produce a global map of Mars that shows some reasonable detail.
Do you see anything in this mosaic that looks interesting? Scientists need to pore over such images, one by one, searching for geology that is both puzzling and revealing. Sometimes the features are obvious, such as a single blobby crater in the flat relatively featureless northern lowlands.
Sometimes however the search can be slow and time-consuming because the terrain is complex, as is the example to the right. The many mesas and canyons can hide many interesting features. Since MRO can’t possibly take high resolution photos of everything, scientists have to pick and choose.
The planetary scientists who use MRO did find something here worth looking at in high resolution. Can you find it? Normally I’d provide a box to indicate it, but this time I’d thought I’d challenge my readers. Before you click below to see the feature, see if you can find it yourself in this mosaic. What would you want to photograph in high resolution?

Today’s blacklisted American: Blackballed professor at NC State sues
Freedom of speech cancelled at
North Carolina State University.
Fighting back: Stephen Porter, a tenured professor at North Carolina State University, has just filed a lawsuit against the university and several of its faculty for blackballing him for simply disagreeing with them on issues of politics and policy.
The introduction of the legal filing [pdf] outlines clearly the actions of the university’s faculty, designed to destroy Porter’s academic career:
[I]n retaliation for Professor Stephen Porter’s protected expressions of opinion on important societal issues, Defendants have intentionally and systematically excluded him from departmental programs and activities that are necessary for him to fulfill his job requirements, effectively hollowing his job out from the inside. They have done this in a deliberate effort to set the stage for his eventual termination. … Defendants are gradually forcing Plaintiff into what is effectively a “rubber room” in retaliation for his criticisms of the so-called “social-justice” ideology that now prevails both in his department and in academia more broadly.
Read the whole complaint. It describes in ugly detail the efforts by his supervisors to isolate and ostracize him so it would be impossible for him to teach and maintain his job.
So, what exactly did Porter do to bring the wrath of these petty dictators down upon him? » Read more
Landing site chosen for VIPER lunar rover
NASA has now chosen the landing site for its VIPER rover, in a relatively flat area about 85 miles from the Moon’s south pole and near the western edge of Nobile Crater (pronounced No-BEEL-e).
The white rectangle on the overview map to the right shows the landing zone. The green cross on the rim of Shackleton Crater marks the South Pole. The red outlines inside craters are regions that are believed to be permanently shadowed, and thus locations that might have water ice within them. Additionally, the data suggests there are a handful of small areas inside craters within the landing zone that might also have ice.
From the press release:
The area VIPER will study in the Nobile region covers an approximate surface area of 36 square miles (93 square kilometers), 10 to 15 miles (16 to 24 km) of which VIPER is expected to traverse through during the course of its mission. During this time, the rover will visit carefully chosen areas of scientific interest that will provide further insight into a wide array of different kinds of lunar environments. The VIPER team will look to characterize ice and other resources in these areas using VIPER’s sensors and drill.
The mission’s planned lifespan is presently set at 100 days. While the Moon’s day/night is 28 days long, the rover will likely see little darkness, since at this very high latitude the Sun will simply circle the sky near the horizon.

SpaceX schedules likely first static fire tests for orbital Starship and Superheavy
Capitalism in space: SpaceX has scheduled a weeklong series of road closures at Boca Chica, beginning next week, suggesting they are about to begin the first static fire tests for the orbital prototypes of both Starship (#20) and Superheavy (#4).
The company has been installing or replacing engines on both prototypes, with the installation apparently now complete on Starship #20.
Starship’s current design features three gimballing sea-level Raptors and three vacuum-optimized variants with much larger nozzles – all in close proximity inside a 9m-wide (30 ft) skirt. As such, the first Starship static fire with any combination of Raptor Center and Raptor Vacuum engines will be a significant milestone for SpaceX. Eventually, that will likely culminate in the first static fire(s) of a Starship (likely S20) with all six Raptors installed – a test that will effectively qualify that prototype for its first orbital launch attempt.
As for Superheavy #4, they have been replacing some of its 29 engines while it sits on the launchpad, for reasons that are not clear.
It appears the company is aiming to get all of its ground-testing completed while the FAA’s approval process for the permit for the orbital flight is ongoing. This will make it possible to launch as soon as approval is obtained.
This strategy carries some risk. As long as the testing proceeds smoothly it will provide positive coverage during the FAA’s public comment period, running until mid-October. Should a test fail dramatically, however, the explosion could generate the wrong response during that comment period. Not surprisingly, SpaceX is willing to accept that risk.

NASA reviewing a dozen commercial proposals for future government space stations
Capitalism in space: Rather than replace the aging International Space Station (ISS) with an entirely government-designed-and-built new station, NASA is now reviewing about a dozen commercial proposals from private companies.
NASA earlier this year unveiled the Commercial LEO Destinations project, with plans to award up to $400 million in total contracts to as many as four companies to begin development of private space stations. In response to NASA’s request, its director of commercial spaceflight, Phil McAlister, told CNBC that the agency “received roughly about a dozen proposals” from a variety of companies for contracts under the project.
…The ISS is more than 20 years old and costs NASA about $4 billion a year to operate. The space station is approved to operate through the end of 2024, with a likely lifespan extension to the end of 2028. But, moving forward, McAlister says NASA wants “to be just one of many users instead of the primary sponsor and infrastructure supporter” for stations in low Earth orbit.
Based on these initial proposals, NASA officials estimate that the agency’s cost for running this future privately-built station will be about $1 billion per year less than the cost for operating ISS.
The agency will also only pay a part of the development cost for the new station, expecting that since the private company or companies will be making money from it also they should front a significant portion of that development cost.
Essentially NASA is following precisely the recommendations I put forth in my 2017 policy paper, Capitalism in space. And as I also predicted, the result is more achievement faster for far less cost.
