No free speech allowed at this college!
They’re coming for you next: Three students at the University of Idaho have sued the college’s administrators for punishing them simply because they publicly defended their religious belief.
Peter Perlot, Mark Miller, and Ryan Alexander are members of the Christian Legal Society [CLS] chapter at the University of Idaho. When Perlot and Miller joined most of the other members of CLS at a “moment of community” gathering to condemn a discriminatory slur written at another campus, a law student approached them to ask why CLS requires its officers to affirm the belief that marriage is between a man and a woman. Miller respectfully explained that the chapter requires this because it is the only view of marriage and sexuality affirmed in the Bible.
Soon after, Perlot left a handwritten note for the student and told her that he would be happy to discuss this further so that they could both be fully heard and better understand one another’s views. A few days later, the student and several others publicly denounced CLS’s actions at a panel with the American Bar Association. Alexander attended that meeting and explained that the characterizations were inaccurate, that the biggest discrimination he had seen on campus was the discrimination against CLS and its religious beliefs, and that he was concerned about the state of religious freedom on campus.
Three days later, the university’s Office of Civil Rights and Investigations issued Perlot, Miller, and Alexander no-contact orders against the student even though the CLS members did not receive notice that anyone had complained about them and were not given an opportunity to review the allegations against them or defend themselves.

In the past week the Mars helicopter Ingenuity successfully completed its 26th and 27th flights, with the first specifically planned to fly over the parachute that had been used by Perseverance when it landed on Mars on February 18, 2021. The first photo to the right, enhanced, cropped, and reduced to post here, is the color photo of that parachute that Ingenuity took during that flight on April 20th. Near the top of the frame you can also see the equipment used to attach the chute to the rover. The photo looks to the southwest.
The map to the right indicates the flight paths for both hops, both slightly more than 1,000 feet total. The green dot marks Ingenuity’s position yesterday, the red dot Perseverance’s position. The small white dot indicates the parachute’s location.
On April 8th Perseverance had snapped a picture of the parachute, from the position indicated by the black dot. Since that photo was taken from a distance, it could not show much. Ingenuity’s more recent photo from overhead however captures the chute quite clearly, and suggests that in the year since landing the weak Martian wind has shifted its edges slightly while depositing some dust on its surface.
You can see the changes at the edges by comparing Ingenuity’s picture with a photo taken on February 19, 2021 by Mars Reconnaissance Orbiter (MRO). In Ingenuity’s picture the near edge of the parachute especially appears to have become bunched up over time, suggesting the prevailing and strongest winds have come from the south.
Capitalism in space: SpaceX early this morning successfully used its Falcon 9 rocket to launch its new capsule, Freedom, carrying four astronauts into orbit and heading to a docking with ISS this evening.
The first stage successfully landed on the drone ship in the Atlantic, completing its fourth flight.
The leaders in the 2022 launch race:
16 SpaceX
11 China
5 Russia
2 ULA
2 Rocket Lab
The U.S. now leads China 23 to 11 in the national rankings. In fact, at this moment the U.S. leads all other nations combined, 23 to 19.
The next launch of a NASA crew to ISS is scheduled to occur tonight at 3:52 am (Eastern) using SpaceX’s new capsule, Freedom, the fourth in the company’s fleet of manned spacecraft. Note too that the first stage of this Falcon 9 rocket will be making its fourth flight into space.
I have embedded the live stream below. As I write this, at 1:19 am (Eastern) the crew has just entered the capsule. Go here for details about the flight, which will be a five month mission.
Commander Kjell Lindgren, veteran of one previous expedition on the space station, leads the four-person crew awaiting liftoff Wednesday. He will be joined by pilot Bob Hines and mission specialist Jessica Watkins, two first-time fliers from NASA’s astronaut corps. European Space Agency astronaut Samantha Cristoforetti, a native of Italy who spent nearly 200 days in orbit in 2014 and 2015, rounds out the crew.
If the launch goes well, Freedom will dock with ISS about sixteen hours later.
If you watch, I must once again note that every person you see aiding the astronauts will be a SpaceX employee. Except for some of the announcers and NASA’s mission control for operating ISS, the launch mission control and everything else is run by this privately owned commercial company.

King’s dream of equal treatment for all
called racist at UCLA
Don’t comply: The lawsuit of Gordon Klein, a professor at UCLA for 39 years who was suspended for three weeks in June of 2021 because he refused to favor black students in grading or exempt them from final exams, will proceed following a favorable ruling by a Los Angeles county judge.
On March 30, 2022, Los Angeles County Superior Court Judge H. Jay Ford III ruled against UCLA when it attempted to have Klein’s lawsuit dismissed. Ford ruled that Klein provided sufficient evidence to “support judgment in his favor” for several of his claims. The lawsuit is scheduled for a jury trial in April 2023.
I covered Klein’s story in a blacklist column in September ’21, describing how Klein was not only suspended but was also subjected to physical threats requiring a police presence at his home.
I also noted that Klein’s lawsuit, available to read here [pdf], specifically targets not just UCLA but “…the individual administrators at the Anderson School personally liable for their wrongful and slanderous actions.” With the lawsuit now proceeding those individuals, specifically Antonio Bernardo, the Dean of the Anderson School, and the entire 26-member Board of Regents of the University of California, are facing punishment for their slanders and bigoted policies.
As always, I strongly recommend my readers spend the time to read Klein’s complaint. Rather than depend on my shortened description, read the whole thing, in all its gory details. You will no longer look at modern academia in the same way. Once an oasis for open discussion, equal treatment, and intellectual thought, established academia has now become a haven for bigotry and hate, focused specifically in destroying anyone who does not support giving minorities favored treatment.
The moving glaciers are mostly thought to be in the dark troughs on
the edge of the dry ice topping the perennial cap, flowing down to
pond on the water ice below.
The uncertainty of science: According to a newly published paper, scientists have concluded that some of the dry ice glaciers at the Martian south pole ice cap are still active and moving, flowing into basins which allow them to survive longer during warm periods.
Carbon dioxide (CO2) ice is found in a stack of deposits at Mars’ south pole. These deposits are situated in basins, where they reach more than 1 km thick. Previous work suggested that the CO2 ice should be deposited when the axial tilt of the planet was lower, making the poles colder than they are now; however, the thickness and distribution of this ice should be much thinner than observed if only atmospheric effects are working on the ice. Therefore, the CO2 ice deposit distribution cannot be explained by atmospheric deposition alone. In this paper, we use glacial modeling and feature analysis to demonstrate that glacial flow better explains the distribution of ice in its present state. In addition, we show that the slopes on the south polar cap act to focus glacial flow into the basins, where it can survive warm periods by sublimating only the uppermost sections when the tilt of the planet is larger than present day.
The scientists estimate that the motion of these glaciers began approximately 600,000 years ago. According to Isaac Smith of the Planetary Science Institute in Arizona, the paper’s lead author:

Capitalism in space: Hawaiian Airlines has now become the second commercial airline company to agree to use SpaceX’s Starlink Wi-Fi on its airplanes.
Hawaiian Airlines said Monday that it will offer free wireless internet service from SpaceX’s Starlink satellite network on flights between Hawaii and the U.S. mainland, Asia and Oceania. The airline said it is in the early stages of putting the service in place on some aircraft next year.
Honolulu-based Hawaiian said it’s the first deal between Elon Musk’s space company and a major airline, although charter operator JSX announced a deal with SpaceX last week.
Expect all the American airlines to soon switch to Starlink. The low orbit of the satellites and its high speed make it superior to the other satellite options presently available.
The InSight science team has now published a paper [pdf] describing in detail what they gleaned from the two large earthquakes the lander detected on Mars last year, measuring 4.1 and 4.2 magnitudes.
The map above, figure 5 of their paper, marks their best estimate of the quakes’ locations, dubbed S0976a and S1000a. From the caption:
Mars surface relief map showing InSight’s location (orange triangle), the location of other located mars-quakes (magenta dots) that cluster around 30° distance, close to Cerberus Fossae, and S0976a, located within Valles Marineris just north of Sollis Planum. Because no back azimuth can be determined for S1000a, its location is predicted to be somewhere within the shaded region between 107° and 147° from InSight. The event’s preferred distance (116°) is marked with the white dashed line. The black dotted lines mark radii around InSight up to 80°.
A review of Mars Reconnaissance Orbiter (MRO) high resolution images of that part of Valles Marineris where S096a occurred will likely uncover a whole bunch taken since last August, all attempting to detect any actual surface changes produced by quake. I think I’ll do that review, and see if I can spot something.
The paper also notes the uniqueness of S1000a, which lasted 94 minutes, the longest so far detected on Mars. The complexity of its signal also makes locating it difficult, though the most likely possible locations — indicated by the white dashed line in the map above — crosses through the Tharsis Bulge where Mars’ biggest volcanoes are found.
Sadly, InSight will likely shut down before the end of this year due to loss of power, so until another seismometer is sent there no further Martian quakes will be detected.
NASA’s SLS rocket has now been rolled back to the vehicle assembly building (VAB) so that engineers can assess the various problems that prevented the agency from completing a full dress rehearsal countdown last week.
Over the next several days, the team will extend the work platforms to allow access to SLS and Orion. In the coming weeks, teams will work on replacing a faulty upper stage check valve and a small leak within the tail service mast umbilical ground plate housing, and perform additional checkouts before returning to the launch pad for the next wet dress rehearsal attempt.
More details about these problems can be found here.
The bottom line is that these engineering fixes are certain to take at least two months to fix. Then NASA must decide what next to do. If it decides to redo the dress rehearsal countdown, then an actual launch cannot happen sooner than July, and only if they proceed directly to launch after completing the rehearsal. If the rocket is rolled back to the VAB after the next rehearsal the launch will be delayed further, into August or September.
And all that assumes the next rehearsal goes perfect, something that seems unlikely based on what has happened so far.
The delays are a problem because the first stage’s two strap-on solid rocket boosters are already well past their “use-by” date of January ’22. The possibility that NASA will have to unstack this rocket and replace these boosters is growing. If that happens the launch cannot occur sooner than early ’23, if then.
Worse, these delays cause all other subsequent SLS launches to be delayed as well. Right now the manned mission to the Moon, presently scheduled for ’25, is likely going to be pushed back to ’26.

Apophis’ path past the Earth in 2029.
NASA today announced that it is extending the missions of eight different planetary probes.
The missions – Mars Odyssey, Mars Reconnaissance Orbiter, MAVEN, Mars Science Laboratory (Curiosity rover), InSight lander, Lunar Reconnaissance Orbiter, OSIRIS-REx, and New Horizons – have been selected for continuation, assuming their spacecraft remain healthy. Most of the missions will be extended for three years; however, OSIRIS-REx will be continued for nine years in order to reach a new destination, and InSight will be continued until the end of 2022, unless the spacecraft’s electrical power allows for longer operations.
The biggest news is the decision to extend OSIRS-REx so that it can rendezvous with the asteroid Apophis in 2029. The science team…
…will redirect the spacecraft to encounter Apophis, an asteroid roughly 1,200 feet (roughly 370 meters) in diameter that will come within 20,000 miles (32,000 kilometers) of Earth in 2029. OSIRIS-APEX will enter orbit around Apophis soon after the asteroid’s Earth flyby, providing an unprecedented close-up look at this S-type asteroid. It plans to study changes in the asteroid caused by its close flyby of Earth and use the spacecraft’s gas thrusters to attempt to dislodge and study the dust and small rocks on and below Apophis’ surface.
Apophis is a potentially dangerous asteroid, with a 1 in 150,000 chance it will hit the Earth in 2068. Getting as much information about it as soon as possible is crucial so that future generations will be prepared should its path eventually become a collision course.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on February 20, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the eroded floor of a 10-mile-wide very obscured unnamed crater that sits above the northern wall of a canyon dubbed Reull Valles.
For reference the interior slope of the crater’s southern rim is labelled. The crater sits at 40 degrees south latitude. Thus, this crater is inside the 30 to 60 degree mid-latitude bands where scientists have found many glaciers on Mars. The eroded floor of this crater appears to confirm this conclusion. In the full photo the erosion is even more pronounced, as well as more chaotic, farther from that rim to the north.
Because Reull Valles sits inside that southern glacial band, it is home to much evidence of ice. The overview map below provides the context.

Musk now a target of the leftist press.
They’re coming for you next: Elon Musk’s effort to buy purchase of Twitter to end the ability of its leftist management and employees to censor opinions they don’t like has apparently activated this same blacklisting effort against Musk and his companies across many media fronts, based on two stories yesterday.
First we have this story in a local Florida newspaper, describing a handful of letters of complaint to the Florida Department of Environmental Protection (FDEP) about SpaceX’s proposal to build an industrial wastewater treatment facility on its leased facility on Cape Canaveral.
The draft proposal was first filed back on February 2, 2022. It requests permission from the Florida Department of Environmental Protection (FDEP) to create a facility that would “discharge up to 3,000 gallons per day of non-process potable water to a stormwater management system that, under specific conditions, discharges to a ditch leading to the Indian River Lagoon.”
After notice of the draft proposal was published in Hometown News Brevard, it drew the attention of Titusville residents.
The article then proceeds to give us a detailed description of each complaint letter sent to FDEP, all five. Based on the similar language in all the letters, they appear to be part of a quickly organized campaign by local environmentalists to block any expansion of SpaceX’s Florida operations. Because of these letters, FDEP has been forced to hold a public meeting today to discuss SpaceX’s proposal.
Next, we have this story from Business Insider: » Read more

Capitalism in space: The Japanese startup Ispace has now obtained the first insurance plan ever for a private lunar lander.
The startup has signed a Memorandum of Understanding with Mitsui Sumitomo Insurance (MSI), a Tokyo-based firm that started working with Ispace in 2019, to insure its first attempt to send a lander to the moon later this year. The agreement outlines intentions to finalize terms for the insurance in the months leading up to Ispace’s Mission 1 (M1), which is currently slated to fly on a Falcon 9 rocket no earlier than the fourth quarter of 2022.
According to Ispace, the insurance would cover any damage the lander takes between separating from the rocket in a trans-lunar orbit (TLO) and touching down on the moon. As well as covering a failed landing, the insurance would guard against issues stemming from radiation exposure as the lander travels through the Van Allen belts to its destination.
The insurance does not cover the payloads Ispace’s lander will carry, including a rover from the United Arab Emirates.
Because of marginal winds at the splashdown points, SpaceX, Axiom, and NASA agreed today to delay the return of Axiom’s first private mission to ISS one more day.
The Axiom Mission 1 (Ax-1) crew is now targeting to undock from the International Space Station 8:55 p.m. EDT Sunday, April 23.
Weather permitting, the Ax-1 crew is targeted to close the hatch at about 6:45 p.m. Sunday, April 24, to begin the journey home in SpaceX Dragon Endeavour with splashdown off the coast of Florida approximately 1:00 p.m. Monday, April 25.
This delay will also delay the launch of NASA’s next crew to ISS on SpaceX’s new Dragon capsule, Freedom, now scheduled for launch no earlier than April 27th.

The string of amazing galaxy images coming from the Hubble Space Telescope continues. The photo to the right, cropped and reduced to post here, was released today and shows an object dubbed VV-689 that is believed to be two galaxies in the process of colliding and merging.
The angelic image comes from a set of Hubble observations that took a closer look at “Zoo Gems,” interesting galaxies from the Galaxy Zoo citizen science project. This crowdsourced program relies on hundreds of thousands of volunteers to classify galaxies and help astronomers wade through a deluge of data from robotic telescopes. In the process, volunteers discovered a gallery of weird and wonderful galaxy types, some not previously studied.
This image will lay the groundwork for more detailed research. Right now it appears no one has even estimated its distance.

Cool image time! The photo to the right, cropped, reduced, and annotated to post here, was taken on October 30, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The picture covers a very tiny section of the southeast flank of Olympus Mons, the largest known volcano in the solar system. The arrow indicates the direction of the downward slope.
Olympus Mons itself is about 400 miles wide with an actual height relative to Mars’ “sea level” of just under 70,000 feet, more than twice as high as Mount Everest on Earth. The mountain’s flanks, almost 200 miles long from caldera edge to base, drop about 54,000 feet. That average drop of about 270 feet every mile is not particular steep, but its continuous nature over such a very very long distance makes its quite daunting.
You can see evidence of that slope in the photo. The downward pointing lobes each indicate the volcano’s last separate lava flows that ceased moving when each froze in place, probably several tens of millions of years ago. These lobes were also placed on top of many earlier flows from the volcano’s past eruptions that probably continued for several billion years, beginning 3.5 billion years ago.
The overview map helps provide a sense of scale by placing this image on that mountain flank.

Capitalism in space: ULA has begin assembling the Atlas-5 rocket it will use in May to launch Boeing’s Starliner manned capsule on its second unmanned demo mission.
The article provides a detailed description of the status of both the rocket and the capsule, including this update on the valve issues that caused the August ’21 launch of this second demo mission to be scrubbed:
Engineers believe the valve components likely corroded from the interaction of nitrogen tetroxide propellant with moisture that seeped into the thrusters on the spacecraft’s service module, then permeated a Teflon seal inside the valve itself.
Technicians removed the service module from the Starliner’s crew module in January for shipment to a test facility in New Mexico, where teams are performing tests to better understand the valve problem. The OFT-2 [in May] mission will fly with a new service module, one originally assigned to the first Starliner mission with astronauts. Teams inside Boeing’s Starliner hangar mated the crew module with the new service module March 12. Filling of the service module with propellant is expected to occur this month, before the spacecraft rolls over to ULA’s rocket integration building for stacking atop the Atlas 5.
Boeing said the Starliner team designed a new purging system to help prevent moisture from getting into the valves during the upcoming launch campaign while the spacecraft is in the factory and at ULA’s launch site.
Boeing’s engineering failures with Starliner have been expensive to the company. Not only has Boeing had to pay out of its own pocket an extra $410 million for this second demo flight, it has had to write off the cost of that first service module. Furthermore, not being operational has probably meant it has lost business to SpaceX and its Dragon capsules. For example, when Axiom first announced it was going to fly commercial tourist flights in 2018, it was expected the company would use both Dragon and Starliner capsules. That might still happen, but at least for the first few years of operations all of Axiom’s business has gone to SpaceX. NASA has also had to throw all its manned flights to SpaceX for the next few years, some of which was originally aimed at Boeing.
Should this second demo flight succeed, however, the company will finally be in a position to launch passengers on Starliner and thus make money from the capsule.
Capitalism in space: Though the company has said little, according to this local Florida newspaper Blue Origin is rethinking its plans to use the cargo ship Jacklyn as a platform for landing its New Glenn first stages in the ocean.
The 600-foot former cargo ship has been docked at the Port of Pensacola since 2018 and undergoing a retrofit by the Pensacola company Offshore Inland to enable the ship to serve as a landing platform for the first stage of Blue Origin’s New Glenn rocket.
When contacted by the News Journal to ask if the retrofit project had been canceled, a Blue Origin spokesperson responded that no final decision had been made yet.
The company is looking at “different options” for recovery vessels that give the best chance for mission success while also being safe and cost-effective, the spokesperson said.
This could be good news or bad news. Either it means Blue Origin is now getting close to finally launching New Glenn, which is three years behind schedule, or it has suddenly realized that using this cargo ship never made sense, and it is scrambling to find a solution at this late date.
The private charter jet company JSX announced yesterday in a tweet that it will begin offering free Starlink Wi-Fi service to its passengers later this year.
According to this article, SpaceX has apparently received its commercial permit from the FCC to offer Wi-Fi on commercial airlines, but it is unclear whether that permit applies to the private charter jets of JSX.
An evening pause: An example of the complexity of technology required to set fair standards in official competitive games — in this case ping pong — that no one ever thinks about.
I especially like the passion and dedication the tester brings to his work, to make sure all is right.

Artist’s impression of solar panel
After months of discussions, the engineering team of the Lucy asteroid probe have now scheduled the week of May 9th as when they will begin their attempt to complete the deployment of the spacecraft’ partly opened solar panel.
The team is now preparing to complete the solar array deployment in two steps. The first step, tentatively scheduled for the week of May 9, is intended to pull in most of the remaining lanyard and verify that flight results are consistent with ground testing. This step will also strengthen the array by bringing it closer to a fully tensioned state. Because this step is designed to be limited in duration, the array is not likely to latch at that point.
If this step goes as planned, the second step will continue the array deployment with the intent to fully latch. Information gleaned from the first part will help fine-tune the second. The second step is currently planned for a month after the initial one, giving engineers enough time to analyze the data seen in the first attempt.
When launched in October 2021 one of Lucy’s two large solar panels did not completely open and latch, as shown above. Though the spacecraft is presently getting 90% of its expected power, the scientists want to get the panel fully open and latched to insure it will function as planned once the spacecraft gets out to the asteroid belt, where sunlight is dimmer.
1964 Civil Rights Act: Arbitrarily voided by the Washington Nationals
Don’t comply: Bernard “Benny” Gallo, a major league baseball scout for the Washington Nationals has sued the baseball team for firing him when he refused for religious reasons to get COVID shots.
Gallo is being represented by the Thomas More Society, which has taken on a number of these cases and won. From the press release:
Serving his employers faithfully through the first 18 months of the pandemic, Gallo was terminated in late August 2021 after being denied a religious exemption by the baseball club. Gallo is seeking to have his firing reversed, his employment reinstated, backpay awarded, and restitution for the malicious deprivation of his rights. When dismissed by the Nationals, Gallo not only lost his livelihood and his life’s passion of working as a baseball scout, but also his elected position as Vice President of the Southern California Scouts Association, a distinction awarded him by his industry peers.
Thomas More Society Special Counsel Charles LiMandri, partner at LiMandri & Jonna LLP, explained that the Nationals instituted a mandatory COVID-19 vaccination policy on August 12, 2021. The mandate required them to have undergone vaccination by August 26. LiMandri pointed out that the Nationals’ team baseball players were not subject to this policy. MLB union members were encouraged to obtain COVID-19 vaccination, but not subject to the mandate.
“The dismissal of Mr. Gallo and the denial of his request for a religious exemption is discriminatory and unlawful,” detailed LiMandri. “The Nationals continued to employ others – including another scout – who requested and received similar accommodations for medical reasons.”
