Today’s blacklisted American: Professor fired by a North Carolina school for having opinions
Dr. David Phillips
They’re coming for you next: Officials at the North Carolina Governor’s School (“a residential summer program for the state’s most talented rising high-school seniors.”) fired David Phillips, a professor there for eight summers, because they did not like the content of the optional three session seminar he held critiquing critical race theory.
In other words, they decided to blackball him simply because they did not agree with his opinions.
Phillips has now sued, with the Alliance Defending Freedom acting as his legal firm. The preamble of his lawsuit [pdf] describes what happened.
At the conclusion of each lecture, members of the audience — including staff members — reacted with open hostility to the ideas and viewpoints discussed. And they attacked whiteness, maleness, heterosexuality, and Christianity — none of which should have been relevant — in their comments and questions. Despite the hostility, Dr. Phillips stayed long after the published end time for each lecture to respond calmly to each question, and he even offered to meet with students and staff members later for further discussion.

Attack that injured Rogozin in the Ukraine also killed two
Dmitry Rogozin playing make-believe soldier
recently in the Ukraine
More details have now emerged about the explosion that injured former Roscosmos chief Dmitry Rogozin, including the fact that the attack, in Ukrainian occupied territory in Donetsk, also killed two.
The former head of Russia’s space agency was wounded when an artillery shell exploded as he celebrated his birthday in a hotel near the front line in Ukraine. Dmitry Rogozin, a flamboyant Russian politician who was once a deputy prime minister, was reportedly hit in the buttocks, head and back by shrapnel.
Two people were killed in the attack and several others were wounded, authorities in Donetsk said on Thursday, and Mr Rogozin said he was due to be operated on. Russian state news channel Rossiya 24 TV said the former space chief was celebrating his 59th birthday at the Shesh-Besh hotel and restaurant with several other separatist officials.
But Mr Rogozin insisted the incident took place during a “work meeting”.
Russian investigators think the shell came from a French-made Caesar self-propelled howitzer.
The criticism of Rogozin concerning this story has been quite ugly.
“A party 10 kilometres away from the front line with the Ceasar’s range of 40 kilometres? I would reprimand him for being childish,” [wrote Yuri Podolyaka, a prominent pro-Kremlin blogger.] “Two people have died in that restaurant, which, I think, is on his conscience.”
Rogozin’s path has been steadily downward since he was deputy prime minister of Russia’s defense department from 2011 to 2018. First he was demoted to head of Roscosmos, where he ended up losing Russia more than a half billion in income by his cancellation of the launch contract with OneWeb. Worse, that cancellation, and Rogozin’s confiscation of 36 OneWeb satellites, ended any chance of Russia getting any international business for years to come.
These actions caused him to be fired from Roscosmos in July, and shipped to the Ukraine (the modern equivalent of Siberia) to act as an envoy in the Russian-occupied territories. Once there, he did nothing to enhance his reputation. By holding this very public birthday party, at a public place so close to the front lines, was almost guaranteeing he and his party would be attacked.
I wish he quickly recovers from his injuries, but I also think Putin would be foolish to give this guy any further positions of authority.
Crater at the edge of the Martian south pole ice cap
Click for full image.
Cool image time! The oblique panorama above, reduced and sharpened to post here, was created from an image taken on May 19, 2022 by the European orbiter Mars Express. Its location on edge of the layered deposits of ice and dust that form most of the Martian southern ice cap is indicated by the white rectangle on the overview map to the right. From the press release:
While it may look like a winter wonderland, it was southern hemisphere spring at the time and ice was starting to retreat. Dark dunes are peeking through the frost and elevated terrain appears ice-free.
Two large impact craters draw the eye, their interiors striped with alternating layers of water-ice and fine sediments. These ‘polar layered deposits’ are also exposed in exquisite detail in the rusty red ridge that connects the two craters.
The scattered white patches are either water frost, or the winter mantle of dry ice, both now sublimating away with the coming of spring.
The black line on the overview map indicates the extent of the layered deposits, and suggest that the ridgeline is not considered part of that ice cap layer, in contradiction to the press release language above.
Which is it? I would guess the answer is simply the uncertainty of science. Some scientists took a look here and decided the ridge was actually a base layer sticking up through the layered deposits. The European scientists who took this picture have instead concluded, based on the image, that the ridge is part of the layer deposits.
Newly passed Senate bill requires consultation between industry and government on space junk
Though the bill still needs to be passed by the House, a just passed Senate bill requires consultation between industry and government on space junk, short circuiting recent attempts at the FCC as well as in the House to impose arbitrary government regulations.
You can read the Senate bill here [pdf].
The final result will still be government regulation on the lifespan and final deposition of any object placed in orbit, from nanosats to large manned space stations, but unlike the earlier FCC proposal and House bill, NASA and other government agencies will have to obtain feedback from the commercial space industry before such regulations are imposed.
Sounds great, eh? In truth, this bill in the end still gives full power to the federal government to control the launching of future spacecraft of all sizes. It also leaves the details entirely up to the bureaucracy. If passed Congress would cede its regulatory power to unelected bureaucrats in the executive branch.
The requirement that industry consultation occur simply means that the initial regulations will likely make some sense. Beyond that however the power it bequeaths to the federal bureaucracy in NASA, FAA, FCC, and other agencies will in the long run be still abused.
The need for the establishment of an independent space-faring society, free from odious Earthbound regulation, continues to grow.
Soyuz hole not caused by a Geminid meteor
According to an analysis by both NASA and Russian engineers, the 0.8 mm hole in the coolant system on the Soyuz docked to ISS was not caused by an object from the Geminid meteor shower that had occurred about the time the leak appeared.
The Soyuz vehicle, known as MS-22, sprayed its coolant into space on Dec. 14, the same day that the annual Geminid meteor shower peaked. But there’s no causal connection, NASA and Russian space officials said. “We did look at the meteor showers that were occurring,” Joel Montalbano, NASA’s International Space Station program manager, said during a press briefing on Thursday (Dec. 22). “Both the trajectory team in Houston and the trajectory team in Moscow confirmed it was not from the meteor showers; it was in the wrong direction.”
The engineers claim the hole could still have been caused by an impact, just not from these meteors.
NASA requesting proposals for raising Hubble’s orbit
NASA has published a request for proposals from the private commercial space industry for a possible future mission to raise Hubble’s orbit.
NASA published a request for information (RFI) Dec. 22 asking industry how they would demonstrate commercial satellite servicing capabilities by raising the orbit of Hubble. The agency said it is looking for technical information about how a company would carry out the mission, the risks involved and the likelihood of success.
NASA emphasized in the RFI that it had no plans to procure a mission to reboost Hubble. “Partner(s) would be expected to participate and undertake this mission on a no-exchange-of-funds basis,” the document stated, with companies responsible for the cost for the mission.
Apparently, this RFI was issued as a direct result of the agreement between NASA and SpaceX to study a Dragon mission to do exactly this, which in turn was prompted by Jared Isaacman, as part of his private Polaris program of manned Dragon/Starship space flights. I suspect that NASA officials realized that not only were their engineering advantages to getting more proposals, there were probably legal and political reasons for opening the discussion up to the entire commercial space community.
Ideally, a Hubble reboost mission should occur by 2025, though the telescope’s orbit will remain stable into the mid-2030s.
Juno experienced data download issue during most recent Jupiter close flyby
Right after Juno made its 47th close fly-by of Jupiter on December 14, 2022, the download of the obtained data was suddenly disrupted, forcing engineers to put Juno into safe mode.
The issue – an inability to directly access the spacecraft memory storing the science data collected during the flyby – was most likely caused by a radiation spike as Juno flew through a radiation-intensive portion of Jupiter’s magnetosphere. Mission controllers at NASA’s Jet Propulsion Laboratory and its mission partners successfully rebooted the computer and, on Dec. 17, put the spacecraft into safe mode, a precautionary status in which only essential systems operate.
As of Dec. 22, steps to recover the flyby data yielded positive results, and the team is now downlinking the science data. There is no indication that the science data through the time of closest approach to Jupiter, or from the spacecraft’s flyby of Jupiter’s moon Io, was adversely affected. The remainder of the science data collected during the flyby is expected to be sent down to Earth over the next week, and the health of the data will be verified at that time. The spacecraft is expected to exit safe mode in about a week’s time. Juno’s next flyby of Jupiter will be on Jan. 22, 2023.
That such disruptions have actually not occurred very often on Juno is somewhat remarkable, considering the hostile nature of the environment around Jupiter.
Perseverance experiment generates new record of breathable oxygen on Mars
MOXIE, an experiment on the rover Perseverance to see if breathable oxygen could be generated from the carbon dioxide in the Martian atmosphere, has set a new production record.
The atmosphere around Jezero Crater, the present location of Perseverance, reached peak density for the year mid (Earth) summer. This presented the perfect opportunity for the MOXIE science team to step on the accelerator and test how fast we could safely produce oxygen. This test occurred on Sol 534 (Aug. 22, 2022) and produced a peak of 10.44 grams per hour of oxygen. This represented a new record for Martian oxygen production! The team was thrilled to surpass our design goal of 6 grams per hour by over 4.4 grams. The peak rate was held for 1 minute of the 70 minutes oxygen was produced during the run.
MOXIE’s next opportunity to operate came recently. Despite the decreasing density of the Mars atmosphere, on Sol 630 (Nov. 28, 2022) MOXIE managed to break the record again and produce nearly 10.56 grams per hour at peak. Oxygen production was sustained for a 9.79 grams per hour for nearly 40 minutes.
These numbers may seem small, but MOXIE production runs are limited by available rover power. In addition, MOXIE technology was miniaturized to accommodate the limited space available on the rover. A MOXIE for a human Mars mission would produce oxygen nearly 200 times faster and work continuously for well over a year.
Ten grams per hour is about half what one person needs to breathe, and is a little less than a large tree produces. Moreover, MOXIE had earlier conducted seven other runs, producing about six grams of oxygen per hour during each.
Based on these tests, MOXIE has unequivocally proven that future human explorers will not need to bring much oxygen with them, and will in fact have essentially an unlimited supply, on hand from the red planet itself. More important, MOXIE has also proven that the technology to obtain this oxygen already exists.
All we need to do is plant enough MOXIE trees on Mars.
