Cool image time! The photo to the right, cropped and reduced to post here, was released today as the picture of the day for the high resolution camera on Mars Reconnaissance Orbiter (MRO). Located in the 2,000 long northern mid-latitude strip that I dub Mars’ glacier country, it shows many of the numerous glacial features that are routinely found in images taken in this region. According to Dan Berman, senior scientist at the Planetary Science Institute in Arizona, who wrote the caption,

This observation shows a lobe-shaped debris apron emanating from a massif (shown in the upper left of the image) in the Protonilus Mensae region in the Northern Hemisphere of Mars. These aprons are composed of nearly pure water ice with a layer of debris on the surface protecting the ice from sublimation (going directly from a solid to gaseous state). This image shows different terrain types on the apron that indicate the presence and flow of ice, from smoother polygonal terrain closer to the massif, to rougher, patterned ground commonly called “brain terrain.” Also visible on the apron are a series of linear pits.

Protonilus Mensae is the central mensae region in that mid-latitude strip of glaciers.The overview map below shows the location of this photo in that region. Also below is a close-up of the linear pits and cracked terrain surrounding that oblong mound, as indicated by the white rectangle.

Pushback against blacklists: Harvard students relaunch conservative newspaper

10:59 am

Among some of Harvard's students, freedom of thought might still exist.
Among some of Harvard’s students, freedom of
thought might still exist.

In an effort to push back against the effort by leftist students at Harvard to silence and blackball conservatives, a group of students have revived the publication of a conservative college newspaper, The Salient, that had folded sometime around 2010.

Harvard student Jacob Cremers, spokesperson for the Salient, said in an email to The College Fix on Nov. 30 that the revival of the paper is meant “to fill the vacuum and to encourage diversity of opinion on Harvard’s campus.”

“The Salient has traditionally served as a source and platform of independent and contrarian thought at Harvard; it seemed to us a shame that it had vanished without leaving another newspaper to take its place,” Cremers said.

About 5,000 copies of the new edition were distributed, he said, including under the doors of every student dorm and over 800 faculty offices on campus. The November 2021 edition was titled: “Revising America: The Deconstruction of the American Commonwealth and the Patriot’s Reply.” It featured eight articles written by students using pseudonyms.

“Pseudonyms are used in order to encourage freedom of expression and attract contributors who would otherwise be too shy of public exposure. The pseudonyms also allow readers to focus on the ideas communicated, rather than the writer behind them,” Cremers told The College Fix. [emphasis mine]

The highlighted quote should be translated: “We allow authors to publish anonymously because we know the intolerant left that dominates Harvard will immediately move to destroy anyone who writes for us, once they find out who they are.”

Significantly, it appears this effort is being funded by alumni and “others” who apparently want to encourage freedom of speech at Harvard while working to break up its monolithic and oppressive leftist culture. After years of sleepy disinterest, it looks like those dedicated to free thought have finally decided to fight.

Right now the plan is to publish The Salient two to three times per year. When the next issue is distributed throughout the college, do not be surprised if the leftist thugs who run Harvard to have organized a plan to steal and destroy all copies. It is the left’s playbook to silence all debate and opposition.

The publishers of The Salient had better be prepared for such thuggery, and arrange the distribution in order to defeat it.

Scientists discover underground reservoir of hydrogen, likely ice, near Martian equator

8:58 am

Detection of underground hydrogen in Valles Marineris
Click for full image.

In what could be a very significant discovery, scientists using Europe’s Trace Gas Orbiter (TGO) have discovered a surprisingly large underground reservoir of hydrogen, likely ice, near Martian equator and inside the solar system’s largest known canyon, Valles Marineris.

The map to the right, reduced to post here, provides all the important data. From its caption:

The coloured scale at the bottom of the frame shows the amount of ‘water-equivalent hydrogen’ (WEH) by weight (wt%). As reflected on these scales, the purple contours in the centre of this figure show the most water-rich region. In the area marked with a ‘C’, up to 40% of the near-surface material appears to be composed of water (by weight). The area marked ‘C’ is about the size of the Netherlands and overlaps with the deep valleys of Candor Chaos, part of the canyon system considered promising in our hunt for water on Mars.

What the caption does not note is the latitude of this hydrogen, about 3 to 10 degrees south latitude. Assuming the hydrogen represents underground ice, this would be the first detection on Mars below 30 degrees latitude, and the very first in the equatorial regions. Data from orbit has suggested that Mars has a lot of water ice, found near the surface more and more as you move into higher latitudes above 30 degrees and making Mars much like Antarctica. Almost no ice however had until now been detected below 30 degrees latitude. As the European Space Agency’s press release noted,

China’s Kuaizhou-1A rocket fails during launch

8:33 am

China’s Kuaizhou-1A rocket experienced its second launch failure on December 14th, though few details about what went wrong have been released.

The Kuaizhou-1A rocket is built by one of China’s pseudo-private companies, Expace.

Expace had been encouraged by three successful Kuaizhou-1A launches across September, October and November, which followed the Kuaizhou-1A being grounded for one year as a result of a failure in September 2020.

Since the rocket’s first three stages use solid rocket motors, it must have been derived from military missile technology. Thus, the company is not private, even if it has obtained Chinese private investment capital, but closely supervised by the Chinese government and its military.

Today’s blacklisted Americans: Google to fire anyone who refuses COVID jab

12:30 pm

Google: a company of oppressive clowns
Google: a company of oppressive clowns.

They’re coming for you next: In a memo to all its employees, Google has announced that it intends to fire any employee who refuses to get any of the COVID shots.

“We expect that almost all roles at Google in the US will fall within the scope of the executive order,” the memo said, according to CNBC. “Anyone entering a Google building must be fully vaccinated or have an approved accommodation that allows them to work or come onsite,” the memo said, adding that “frequent testing is not a valid alternative to vaccination.”

The company will give those lacking the jab six months of unpaid leave to get it, after which they will be terminated. It also appears that it will not matter whether the employee is working remotely or is coming into the office. Google wants everyone to get COVID shots, and will use force if necessary to make them do it.

The insanity of this rule is breath-taking. The evidence now shows that the various COVID shots are generally ineffective over the long run in protecting the population from getting the Wuhan flu. Thus, making employees get these shots is silly, and irrational.

It also violates numerous civil rights and privacy laws. First, Google has no right to demand this medical information from its employees. Second, to blackball certain employees because of their personal medical decisions is certainly discriminatory and violates their civil rights.

So, why are you still using gmail? Why are you still using Google as your default search engine? Both are easily replaced, especially the latter, and until you get rid of both you need to be logged into this unethical and oppressive company, which means it is collecting data from you continuously, for its own use.

For the same reason, I beg my readers who like to suggest evening pauses to look at other video sites, like Rumble and Vimeo, before relying on Google-owned YouTube. We need alternatives from a company that not only censors and blacklists conservatives, but now clearly wants to discriminate against some of its employees.

Visible clean water ice on Mars

Crater with ice scarp
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, is today’s picture of the day for the high resolution camera on Mars Reconnaissance Orbiter (MRO). Taken on September 13, 2021, it shows an exposed scarp on the southern inner wall of a small 800-foot-wide crater.

What makes that scarp intriguing is its blue color. As noted by Shane Byrne of the Lunar and Planetary Lab University of Arizona, who wrote the caption:

This north-facing cliff appears to expose icy material that’s similar to other pole-facing scarps showing buried ice elsewhere on the planet. These cliffs give us a cut-away view of the buried ice in that location and can help answer questions about what the Martian climate was like when this ice formed.

The crater itself sits inside a much larger crater, as shown in the wider picture below.

Scientists confirm Parker entered Sun’s corona in April 2021

9:40 am

Scientists yesterday announced that the Parker Solar Probe successfully entered the Sun’s corona for the first time during its April 2021 close fly-by.

More information here, including some excellent short movies made from images created by Parker’s instruments.

The top edge of the corona is dubbed the Alfvén surface, and Parker’s passage across that boundary three different times during the April ’21 fly-by revealed it to be a sharp boundary that also has a great deal of topography. From the second link:

The first time Parker passed the Alfvén surface was the longest; it flew through the atmosphere for about five hours. Even as it continued flying toward the Sun, though, it popped back out, only to submerge again more deeply when it was at its closest approach — but briefly, that time exiting after just half an hour. Then, on its way outward, the spacecraft once again skimmed beneath the surface for a few hours.

“[The Alfvén surface] has to be wrinkly,” Kasper says. “It’s not fuzzy — it’s well-defined while we’re under it — but the surface has some structure to it.” So while the probe sees a smooth change in conditions while crossing the boundary, where the boundary is can change. The reason for this wrinkly surface is still an open question, though the researchers suspect the crossing over a pseudostreamer lower in the corona pushed the boundary out to enable the first crossing.

What’s clear is that inside the Sun’s atmosphere, conditions are different than just outside. Parker saw plasma waves moving back and forth instead of flowing outward. That difference was visible not just to the SWEAP and FIELDS instruments, which measure particles and electric and magnetic fields, respectively, but also to the probe’s WISPR imager.

The Parker science team also indicated that the preliminary data from the probe’s next two fly-bys — the most recent in November that was the closest yet — suggest it passed through the corona then as well.

One of the biggest unsolved mysteries about the Sun’s corona is that it appears to have a temperature in the millions of degrees, far hotter than the Sun’s surface below, something that is counter-intuitive. The expectation was that the atmosphere would be cooler than the surface. Finding out why the corona is hotter is one of the main science goals of Parker. It appears the probe is finally gathering data that might help solve that mystery.

Webb launch delayed two days because of ground equipment issue

9:42 pm

After engineers at Arianespace’s French Guiana launch facility found an intermittent issue with ground equipment related to the Ariane 5 rocket launching the James Webb Space Telescope, it was decided to delay the launch two days to make sure the problem was resolved.

n a brief statement, NASA wrote on its website late Tuesday that the Webb team is “working a communications issue between the observatory and the launch vehicle system.”

Thomas Zurbuchen, associate administrator for NASA’s science mission directorate, said Tuesday that engineers found an “interface problem” in a system that communicates with Webb while it’s on top of the Ariane 5 rocket. “The way to think about it is it’s a ground support equipment thing,” Zurbuchen said Tuesday night in an interview with Spaceflight Now. “Basically, the data cables are dropping some frames.”

Technicians inside the Ariane 5 rocket’s final assembly building in Kourou have tried to diagnose the problem, but so far, haven’t been able to resolve it.

The December 24th target day date remains tentative, and could slip to December 25th, or even later, depending on how successful engineers are at fixing the issue.

Enrollment plunges when students are no longer forced to take critical race theory class

11:34 am

Freedom of thought might still exist at St. Joseph's
Among the students, freedom of thought might
still exist at St. Joseph’s University.

A victory for free thought: When students at St. Joseph’s University in Pennsylvania were no longer required to take a class promoting race and the anti-white agenda of critical race theory, enrollment dropped so much that most of the offered classes will likely be canceled.

The university’s campus paper noted:

Multiple sections of the university’s new one-credit diversity course, Inequality in American Society (INT 151), are at risk of getting canceled for the spring 2022 semester due to under enrollment.

As of Dec. 4, only four of the 26 sections offered for the spring 2022 semester are full, according to numbers on the Course Registration website. Twelve of the 26 sections have 50% or more seats still available.

Of course, the teachers who are promoting this racist class want this problem solved by making the class a requirement. More important, these teachers are not really interested in diversity of thought, as illustrated by this comment by professor Brian Yates, the course’s leading advocate:
