Today’s blacklisted American: Professor quits because of the leftist takeover of his college

2:13 pm

Matthew Wielicki
Matthew Wielicki

Matthew Wielicki, a professor at the University of Alabama, has quit his job because of what he calls the “rise of illiberalism” as well as the takeover of the college by the leftist diversity, equity and inclusion (DEI) crowd.

While Matthew Wielicki said his main reason for leaving Tuscaloosa was to be closer to family in Colorado, the “rise of illiberalism” made his decision easier. “The rise of illiberalism in the name of DEI is the antithesis of the principles that universities were founded on,” Wielicki tweeted Monday. “These are no longer places that embrace the freedom of exchanging ideas and will punish those that go against the narrative.”

Curiosity looking back

9:22 am

Panorama by Curiosity, looking back
Click for full image.

Overview map
Click for interactive map.

Curiosity is now about halfway across the flat marker band terrain it faced last week, and as part of its routine, used its right navigation camera on January 28, 2023 to create a 360 degree panorama mosaic of the Mount Sharp foothills that now surround it. The panorama above, cropped, reduced, and sharpened to post here, focuses on the part of that mosaic looking behind Curiosity.

You can see the rover’s recent tracks as it crossed this part of the marker band. In the far distance can be seen in the haze the rim of Gale Crater, approximately 20 to 40 miles away. The yellow lines in the overview map to the right show the approximate area covered by this section of the panorama. It is possible the peak of Navarro Mountain is peeking up in the center of this panorama, but more likely it is no longer visible, blocked by the smaller but closer hills.

As Curiosity is now inside the foothills of Mount Sharp, the floor of Gale Crater is no longer easily seen. The rover needs to be at a high lookout point, something that will likely not occur in its travels for many months if not years to come.

The Curiosity pictures I am featuring this morning are cool, and they are also the only real news in the space field at this moment. As is usual on Monday, it takes few hours for the news at the beginning of the week to make itself known.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

A cloud on Mars

8:46 am

A cloud on Mars
Click for original image.

Cool image time! The photo to the right, reduced and sharpened to post here, was taken on January 27, 2023 by Curiosity’s high resolution camera (dubbed Mastcam) as part of its periodic survey of the sky, looking for clouds. Most of the time the sky is either hazy or clear. This time the camera picked up this cloud, which resembles a cirrus cloud on Earth.

In March 2021 I posted another example of clouds found above Gale Crater by Curiosity. Two months later the science team released a press release about those clouds, which might help explain the cloud above.

The fine, rippling structures of these clouds are easier to see with images from Curiosity’s black-and-white navigation cameras. But it’s the color images from the rover’s Mast Camera, or Mastcam, that really shine – literally. Viewed just after sunset, their ice crystals catch the fading light, causing them to appear to glow against the darkening sky. These twilight clouds, also known as “noctilucent” (Latin for “night shining”) clouds, grow brighter as they fill with crystals, then darken after the Sun’s position in the sky drops below their altitude. This is just one useful clue scientists use to determine how high they are.

Even more stunning are iridescent, or “mother of pearl” clouds. “If you see a cloud with a shimmery pastel set of colors in it, that’s because the cloud particles are all nearly identical in size,” said Mark Lemmon, an atmospheric scientist with the Space Science Institute in Boulder, Colorado. “That’s usually happening just after the clouds have formed and have all grown at the same rate.”

Though usually formed from water-ice, there is a chance this cloud is formed from crystals of dry ice. More analysis will of course be necessary to make that determination.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Today’s blacklisted American: Jesus painting at U.S. Merchant Marine Academy covered to avoid offending others

11:28 am

USSMA Superintendent Vice Admiral Joanna Nunan
USSMA Superintendent Vice Admiral Joanna Nunan

They’re coming for you next: A painting showing Jesus walking on water in a room at the U.S. Merchant Marine Academy in New York has now been covered with a curtain because eighteen “midshipmen, faculty, staff and graduates” signed a letter of complaint.

Calling the artwork a display of “sectarian Jesus supremacy,” [Mikey Weinstein, founder of the Military Religious Freedom Foundation who represented the complainants,] noted the room in which the painting is hung is used for various administrative meetings, disciplinary hearings and other events. “The outrageousness of that Jesus painting’s display is only further exacerbated by the fact that this room is also used regularly for USMMA Honor Code violation boards where midshipmen are literally fighting for their careers, and, often even more, as they face the shameful ignominy of potential expulsion with prejudice if found guilty of USMMA Honor Code violations,” wrote Weinstein.

Weinstein told The Christian Post his clients “quite correctly believe that the display of the ‘Jesus painting’ is totally violative of the clear time, place and manner requirements of the No Establishment Clause of the U.S. Constitution.”

The problem is that the painting was not created by the federal government. Its history is much more profound.

Glaciers or taffy on Mars?

Glaciers of taffy on Mars?
Click for full image.

Cool image time! The photo to the right, rotated, cropped, reduced, and sharpened to post here, was taken on November 28, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It was released on January 4, 2023 as a captioned image, with this caption by Alfred McEwen of the Lunar & Planetary Laboratory in Arizona:

The floor of the Hellas impact basin, the lowest elevation on Mars, remains poorly explored because haze often blocks it from view. However, we recently got a clear image, revealing the strange banded terrain. These bands may be layers or flow bands or both.

At first glance, these bands reminded me of the many glaciers found on Mars. McEwen however is being properly vague about the nature of these features, for a number of reasons illustrated by the overview map below.

The twin asteroid Janus probes, stranded by Psyche delay, might go to Apophis

9:20 am

Apophis' path past the Earth in 2029
A cartoon showing Apophis’s path in 2029

The science team that built the twin Janus spacecraft, designed to fly past an asteroid but stranded when its launch got canceled, are now considering the potentially dangerous asteroid Apophis as a new target.

If the Janus spacecraft can find a ride by early 2028, scientists could use one or both of the spacecraft to scout out the large asteroid Apophis before its super-close approach to Earth in April 2029. (If only one spacecraft visits Apophis, scientists would see only about half of the asteroid but could send the second spacecraft elsewhere; if both spacecraft fly past the same object they can be arranged to reveal the whole surface.)

Initially the entire Janus mission had been designed on the assumption it would launch as a secondary payload when the Psyche mission to the asteroid Psyche launched last fall. When that launch had to be canceled because Psyche was not ready, Janus lost its mission. The science team has since been struggling to find a replacement, handicapped by the fact that it must go as a secondary payload.

There is a serious issue however with arriving ahead of Apophis’s close approach in 2029. The science community has discouraged such missions, because they fear a spacecraft arriving then could shift Apophis’s trajectory and actually increase the chance it will hit the Earth during a later close approach. Instead, all planetary probes presently going to Apophis in 2029 are planning to arrive after the flyby.

The risk is extremely small, but it must be considered before sending Janus to Apophis.

Pushback: Two reporters sue ESPN for terminating them for not getting jabbed

12:35 pm

ESPN-opposed to religious freedom

Bring a gun to a knife fight: Two former ESPN employees, sports reporter Allison Williams and producer Beth Faber, have now sued the network and its owner Disney for religious discrimination when it refused to recognize their religious reasons for refusing the COVID shots and thus terminated them.

You can read their complaint here [pdf]. The thuggish, unreasonable, and irrational attitude of the company to both employees — typical of all pro-jab organizations during the Wuhan panic — is well illustrated by this quote:

Despite offering to test regularly and wear a mask, work remotely or in-studio, and claiming she had already had COVID-19 and “had natural immunity,” ESPN denied her exemption request and terminated her contract a week later, according to the suit.

Nor is this lawsuit the only one against ESPN by a sports reporter. » Read more

A Martian bear!

A Martian bear!
Click for original image. Full image here.

Silly image time! Today the science team for the high resolution camera on Mars Reconnaissance Orbiter posted the photo to the right, which I have cropped, reduced, and annotated to post here. It was taken on December 12, 2022, and was rotated so that north is to the right in order to make its resemblance to a bear’s face obvious. As noted in the caption by Alfred McEwen of the Lunar & Planetary Laboratory in Arizona:

There’s a hill with a V-shaped collapse structure (the nose), two craters (the eyes), and a circular fracture pattern (the head). The circular fracture pattern might be due to the settling of a deposit over a buried impact crater. Maybe the nose is a volcanic or mud vent and the deposit could be lava or mud flows?

Maybe just grin and bear it.

If you have red-green glasses you can see a 3D anaglyph of this image here. The feature itself is located in the southern cratered highlands of Mars at 41 degrees south latitude, so the presence of near surface ice that would cause a mud volcano is definitely possible.

NASA and Russian engineers meeting to discuss status of leaks on ISS’s Zvezda module

9:40 am

According to Russia’s state-run press, NASA and Russian engineers have been reviewing the status of the repairs on the cracks in the Zvezda module on ISS.

Repairs to the various cracks in Zvezda’s hull, done by Russian astronauts in ’20 and ’21, have reduced the leakage from 1,140 grams per day to 300 grams per day. Normally ISS is expected to lose 325 grams per day, across the entire station, so the Zvezda leak doubled this loss, even after the repair. Thus, the hatch to Zvezda is kept closed in order to maintain the atmosphere of ISS at its normal levels, and opened only when there is need to enter it. In addition, its port is no longer used for dockings.

The engineering review is also looking into the cause of the cracks, which are believed to be stress fractures caused by the age of Zvezda (ISS’s second oldest module) combined with the many dockings that had occurred at its port. The review is also discussing ways to reduce the problem, until ISS’s retirement in 2030.

German rocket startup Isar Aerospace gets first American customer

9:28 am

The German rocket startup Isar Aerospace, which hopes to complete the first launch of its Spectrum rocket this year, has signed its first launch contract with an American company, the satellite broker and space tug company Spaceflight.

U.S.-based launch services provider Spaceflight said Jan. 25 it has booked a dedicated launch in 2026 from Isar Aerospace, the German rocket developer aiming to perform the first test flight of its Spectrum vehicle this year. The mission is slated to lift off from Isar’s launchpad in Andøya, Norway, to sun-synchronous orbit (SSO).

Their agreement also includes an option for an additional dedicated launch in 2025, which Isar chief commercial officer Stella Guillen told SpaceNews could also use a launchpad it is developing at the Guiana Space Center near Kourou, French Guiana.

Spaceflight has been scrambling to find rockets for its tugs, since SpaceX announced in March 2022 it would no longer carry them. It signed a deal with Arianespace to fly on its Vega rocket, but launch failures have delayed its launch.

Isar is one of three German rocket startups vying for business. The race to be the first to launch remains very tight.

Lucy's route through the solar system
Lucy’s route through the solar system

The Lucy science team has now added a tenth asteroid to the spacecraft’s tour of the solar system, planning its route so that it will pass within 280 miles on November 1, 2023.

The Lucy mission is already breaking records by planning to visit nine asteroids during its 12-year tour of the Jupiter Trojan asteroids, which orbit the Sun at the same distance as Jupiter. Originally, Lucy was not scheduled to get a close-up view of any asteroids until 2025, when it will fly by the main belt asteroid (52246) Donaldjohanson. However, the Lucy team identified a small, as-yet unnamed asteroid in the inner main belt, designated (152830) 1999 VD57, as a potential new and useful target for the Lucy spacecraft.

The asteroid is about 2,300 feet wide. The primary goal of this visit however will be engineering, testing Lucy’s new method of tracking an object as the spacecraft flies past. On the map to the right the dots along Lucy’s path indicate the asteroids to be visited.

Today’s blacklisted American: Thin blue line banned on flags in Los Angeles and suburban Philadelphia

2:13 pm

They’re coming for you next: Today’s blacklist story illustrates most starkly the intolerant and insane culture that is now taking over many Democratic Party-controlled regions of the United States. Government officials in both Los Angeles and the town of Springfield, a suburb of Philadelphia, have banned use of the American flag with a thin blue line that for years has been used to symbolized support of the police and those who have fallen in duty.

In both cases, the banning occurred because some leftists made unsubstantiated accusations that the line really represented “white supremacy” and thus is racist. No evidence of course was ever presented to prove those allegations, but who cares about evidence in this day and age? All that matters is that the accusation is made, and all must immediately kow-tow to it, even if it destroys the first amendment and the lives of many innocent people.

LA police chief Michael Moore
LA police chief Michael Moore

Now for the specifics. In Los Angeles the chief of the LA police department on January 13, 2023 banned the use of the flag after receiving one complaint.

The “Thin Blue Line” flag has been banned from Los Angeles Police Department lobbies along with all other public areas on police property following a complaint from one person who thought it signified support for “extremist” ideologies such as “those espoused by the Proud Boys,” according to the chief.

LAPD Chief Michel Moore sent an email to department personnel on Friday making the announcement to remove the flags, blaming “extremist groups” who have “hijacked the use” of the Thin Blue Line.

Moore was desperate to protect the sensitive feelings of that one person, even though no evidence at all was presented to prove the allegations, and the police union and its nearly 10,000 members were utterly opposed to his decision.

A dry lakebed on Mars?

12:37 pm

Evidence of a past lake in a crater on Mars
Click for original image.

Today’s cool image illustrates in some ways the uncertainty of science. The photo to the right, rotated, cropped, reduced, and sharpened to post here, was taken on December 1, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team intriguingly labeled it “Small Candidate Lake Deposit Downstream of Alluvial Fan.” I am not sure what they consider that lake deposit in the full image, so I have focused on the area of stucco-like ground, which resembles bedrock that has been corroded by some water process.

This area is just to the east of the central peaks of an unnamed 25-mile-wide crater in the southern cratered highlands. Many of the craters in this region are believed by scientists to have once harbored lakes formed by run-off from the glaciers that once existed on the craters’ inner rim. In this case it appears this stucco area is the head of an alluvial fan, coming down from the crater’s central peaks. You can see its beginning in this MRO high resolution image of the central peaks, taken in November 2016. As defined geologically,

An aluvial fan is an accumulation of sediments that fans outwards from a concentrated source of sediments, such as a narrow canyon emerging from an escarpment. They are characteristic of mountainous terrain in arid to semiarid climates, but are also found in more humid environments subject to intense rainfall and in areas of modern glaciation.

In this case the terrain is now arid, but shows evidence it once was icy wet.

ISRO about to test land a prototype of India’s own version of the X-37B

9:46 am

ISRO's own X-37B copy

According to S. Somanth, the head of India’s space agency ISRO, it will attempt the first flight on January 28, 2023 of a prototype reusable launch vehicle, similar to the Space Force’s X-37B.

According to ISRO’s website, Saturday’s landing demonstration will involve a “landing experiment (LEX)” in which the RLV will be carried using a helicopter to an altitude of 3-5 km and released at approximately 4-5 km from the runway with a horizontal velocity.

After the release, the RLV glides and navigates toward the runway, and carries out a conventional autonomous landing. This is planned in a defence airfield near Chitradurga in Karnataka.

The graphic to the right shows the flight profile of earlier tests that landed in the ocean. If this runway test is successful, it appears ISRO will next attempt an orbital flight and return.

Arianespace’s chief condemns the idea of independent private European rocket companies

9:31 am

Stéphane Israël, the head of Arianespace, the European Space Agency’s (ESA) commercial rocket division, yesterday strongly condemned the idea of allowing independent private European rocket companies to develop and compete with his government operation.

“It is not possible to copy-paste the US model,” he said. “It is not possible. The level of space spending in the United States is five times higher than in Europe, and the private capital is not the same. So if the answer is to say let’s do what the US has done, I think we will not manage to do it.”

Moreover, Israël said the European Space Agency must resist supporting microlaunchers to the point where these companies might compete with the existing capabilities.

“A huge mistake would be that this focus on microlaunchers destabilizes Ariane 6 and Vega C—it would be a historic mistake,” he said. “Microlaunchers can be of support to boost innovation. But we should not make any confusion. This launcher will never give autonomous access to space to Europe. They’re on a niche market representing maybe 10 percent of the market, and less than that when it comes to European needs.”

He said this in Brussels at the 15th European Space Conference, where it appears he was trying to convince the ESA to block any competition with Arianespace.

Israël might say this, but not only has his track record in predicting the success of commercial space in the U.S. been bad, other European governments are not taking his advice. Both Germany and the United Kingdom have several rocket startups gearing up for their first launches this year, with others in Spain and France not far behind. Moreover, Israël doesn’t have much to offer in competition. Arianespace’s Vega rocket, intended to be a low cost option, has failed on three of its last eight launches. The Ariane 6 rocket is years behind schedule, and has not yet launched. And both are overpriced and cannot compete, not only with the American rocket startups but with India’s government rockets.

Moreover, those European governments have in recent years been taking control and power away from Israël and Arianespace. Unlike earlier rockets, the Ariane 6 rocket is not controlled or owned by Arianespace. Instead, it belongs to ArianeGroup, the partnership of Airbus and Safran that is building it. Arianespace’s role in operating it will be greatly limited, once it begins flying.

Roscosmos predicts Russia’s new space station will launch by 2027

9:14 am

Wanna bet? Yuri Borisov, the head of Roscosmos, yesterday predicted that Russia’s new space station, dubbed the Russian Orbital Station, will launched and deployed by 2027.

“We will create sovereign infrastructure for human space flights to low near-Earth orbit. Its key element will be the Russian orbital station whose deployment we have scheduled for 2027,” he said.

The Russian space agency will carry out all the required feasibility studies by Cosmonautics Day celebrated in Russia on April 12, the Roscosmos chief said.

Based on Russia’s track record for the past three decades, this prediction will fail. Since the fall of the Soviet Union Russia’s space industry has consistently made many such predictions, none of which launched on time, with most never launching at all. Yet, that was during a time when Russia’s economy was booming, it was getting lots of revenue from the international markets, and wasn’t saddled with a draining war in the Ukraine. Now, international sanctions limit what it can get from that market, and its oil revenues have declined considerable due to the war. Moreover, the war prevents Russia from obtaining many cutting edge space components it needs for such a project. Replacing these with home-built components will take time.

If this station gets built, its launch will likely not happen before 2030.

Stacked Starship and Superheavy complete first full wet dress rehearsal countdown

9:06 am

SpaceX yesterday successfully completed a full wet dress rehearsal countdown of its stacked Starship prototype #24 and Superheavy prototype #7, fueling both completely and taking the countdown down to T-0.

On this rehearsal however the Superheavy engines were not fired. From two SpaceX tweets:

Starship completed its first full flight-like wet dress rehearsal at Starbase today. This was the first time an integrated Ship and Booster were fully loaded with more than 10 million pounds of propellant

Today’s test will help verify a full launch countdown sequence, as well as the performance of Starship and the orbital pad for flight-like operations

Next step: Another full wet dress rehearsal countdown that includes a short static fire test of all 33 Superheavy Raptor-2 engines. Once that is done successfully, the company will be ready for that first orbital launch.

Meanwhile, SpaceX awaits its launch license from the FAA. I remain pessimistic that it will be issued on a timely manner, as there are clear signs the Biden administration wants to use its power against Musk, whom it now sees as an enemy.

Classified Chinese test satellite releases second object in orbit

8:55 am

A classified Chinese test satellite, launched on January 8th, apparently released a second object into orbit on January 16th, suggesting the satellite might be doing robotic rendezvous and docking tests, similar to tests by an earlier classified satellite.

China’s Shijian 21 satellite, which launched in 2021, also reached GEO and released a satellite, which was then used for tests. Shijian 21 then proceeded to dock with the defunct Chinese navigation and positioning satellite Beidou-2 G2 and towed it away to an orbit out of the way of the active spacecraft in GEO.

China is clearly attempting to develop the same robotic servicing technologies that commercial companies in the west are beginning to fly.

Russians successfully test replacement Soyuz capsule for leaks

8:49 am

The next Soyuz capsule to launch to ISS has now been passed its leak tests on the ground as it is being prepared for a February 20th launch.

“At the Baikonur cosmodrome, leak tests of the Soyuz MS-23 transport crewed spacecraft have been completed,” the [Roscosmos press release] said. In the coming days, checks of the propulsion system’s automation equipment, onboard digital computerized system and radio engineering systems will follow. Also, the thermal control system is to be filled with a coolant.

The launch has been moved up one month in order to speed the replacement of the leaking Soyuz presently on ISS.
