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

12:05 pm

Silenced by Twitter, Facebook, YouTube, and Google
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

9:19 am

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

9:08 am

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.

Today’s blacklisted American: Weatherman fired after 33 years for not getting COVID vaccine

12:03 pm

Weatherman Karl Bohnak, now a non-person
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

Martian mountaintop

Mountains on Mars

The outcrop top
Click for full image.

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.

Firefly selling its rocket engines to Astra

10:32 am

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

10:21 am

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

9:33 am

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

9:20 am

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

9:05 am

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.
