A Martian slope streak caused by a dust devil?

A Martian slope streak caused by a dust devil?
Click for original image.

Cool image time! The photo to the right, cropped, sharpened, and enhanced to post here, was taken on January 5, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the interior slope of an unnamed 9-mile-wide crater, located just south of the Martian equator.

On that slope are several slope streaks, their dark color suggesting they are relatively recent. Also on that slope is the track of a dust devil that traversed that across slope. The track and the top of one of those streaks match, suggesting the dust devil might have caused the streak.

Did it? Maybe. This image was certainly taken to try to find out. Right now scientists do not know what causes slope streaks, a phenomenon unique to Mars. Though they look like avalanches, they do not change the topography at all, and sometimes flow over rises. If anything, they appear to be a stain on the surface, caused by some unknown process.

Today’s blacklisted American: CVS fires nurse for refusing to violate her religious beliefs

Robyn Strader
Robyn Strader

They’re coming for you next: Despite accommodating nurse practitioner Robyn Strader’s religious beliefs for more than six years, CVS fired her on October 31, 2021 after suddenly deciding that the Christian religion was no longer valid and no employees could cite it when it came time to prescribe drugs.

Robyn worked at a CVS MinuteClinic in Keller, Texas since 2015. Robyn sought a religious accommodation because prescribing any medications that could intentionally end the development or life of an unborn child would force her to violate her beliefs. For six-and-a-half years, the company accommodated her without a problem. When someone requested such a medication, usually only a few times per year, Robyn referred them to another practitioner at her location or to another MinuteClinic located just a couple miles away.

But CVS reversed course, joining the ranks of the “woke” corporations rendering religious employees second class citizens. In 2021, the company stated it would no longer honor religious accommodations related to such medications. Soon after this policy was put in place, CVS terminated Robyn.

Strader is now suing, with the non-profit legal firm First Liberty representing here. You can read her lawsuit here [pdf].

Space station builder Voyager raises $80 million in private investment capital

Capitalism in space: Voyager Space, one of three companies that NASA has provided funds to build a private space station, has now raised $80 million in private investment capital.

The funding includes participation from NewSpace Capital, Midway Venture Partners and Industrious Ventures, according to U.S. Securities and Exchange Commission filings and other documents viewed by TechCrunch. Seraphim Space also participated, TechCrunch has confirmed. The funding was filed with the SEC on January 27.

The company is building Starlab in partnership with Nanoracks (which is the majority owner of Voyager) and Lockheed Martin, which has already received $160 million from NASA.

Yanni – Aria: Ode to Humanity

An evening pause: I posted an earlier performance of this in 2016, but that is no longer available on youtube. This is newer performance is without doubt as magnificent.

Hat tip Alton Blevins.

Razor butte on Mars

Razor butte on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on November 18, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team labeled this image “Inverted Channel and Possible Lake Deposits.” The sharp razor-like butte, which I estimate is about 200 to 400 feet high, is an example of the several inverted channels in the full image. The serrated-edged flat plateau at the top of this picture, one of several in the full image, is an example of those possible lake deposits.

Why do the scientists think a lake might have once been here? Located at 8 degrees north latitude in the dry equatorial regions of Mars, there is almost certainly no near surface ice here now.

As always, the overview map provides the context, and a possible explanation.

Sunspot update: Sunspots in January went through the roof!

NOAA this week updated its monthly graph that tracks the number of sunspots on the Sun’s Earth-facing hemisphere. Below is that updated graph, with January’s numbers added to the timeline. As I have done monthly for the past dozen years here on Behind the Black, I have added some additional details to that graph to provide context.

Just as in December, the number of sunspots in January 2023 shot up to the highest amount since September 2014, which was during the previous solar maximum. Unlike December, however, January’s numbers came only a hairs-breath from topping that 2014 number. In fact, except for that one 2014 month, January 2023 saw the most sunspots on the Sun since November 2002, twenty years ago. In 2002 the Sun was ramping down from what had been a relatively strong double-peaked solar maximum, and was about to begin an extremely long period of little or no activity, followed by a very weak double-peaked solar maximum in 2013.

That period of little activity also corresponded with a long twenty-year period in which the Earth’s climate appeared to stop warming.

Today’s blacklisted American: Comic book writer slandered and then canceled because of the slanders

Mike Baron's Private American, banned

They’re coming for you next: Long established comic book writer Mike Baron and his projects have now been blacklisted from a variety of sites, including having his most recent Kickstarter starter campaign shutdown, because of slanderous social media comments as well as a defamatory article on Daily Kos.

After a scathing article from a Daily Kos mouthpiece, Baron’s colleagues and fans realized they could not find his campaign on Kickstarter. The post smeared “Thin Blue Line” – a story about two police officers riding out a long night of rioting – along with “Private American.” The author, a person named Starr Mignon, called the comic a “diatribe of racist propaganda” and “stochastic terrorism disguised as a funny book.”

Prior to Kickstarter shutting his campaign down, it had also been banned from Twitter, as well as shadow-banned on Indiegogo.

A detailed blow-by-blow description of the slanderous attacks, based on no knowledge of these works, as well as the cowardly blackballing by others in response to those attacks, can be found here. This writer, who was helping Baron’s campaign, notes the following:

NASA switches lunar landing site for Astrobotic’s Peregrine lander

Peregrine landing site

NASA today announced that it has changed the planned landing site on the Moon for Astrobotic’s Peregrine lunar lander, presently scheduled for launch at the end of March on the first flight of ULA’s new Vulcan rocket.

The original landing site for Astrobotic’s flight within Lacus Mortis, which is in the northeast quadrant of the lunar nearside of the Moon, was chosen by Astrobotic to suit its lander performance and safety, as well as Astrobotic’s preferences. However, as NASA’s Artemis activities mature, it became evident the agency could increase the scientific value of the NASA payloads if they were delivered to a different location. The science and technology payloads planned for this delivery to the Moon presented NASA scientists with a valuable opportunity, prompting the relocation of the landing site to a mare – an ancient hardened lava flow – outside of the Gruithuisen Domes, a geologic enigma along the mare/highlands boundary on the northeast border of Oceanus Procellarum, or Ocean of Storms, the largest dark spot on the Moon.

The white dot on the map to the right shows this location. The original location was to the west of Atlas Crater in the northeast quadrant of the Moon’s near side, where Ispace’s Hakuto-R lunar lander plans to touch down in April.

This decision by NASA was apparently prompted by the decision to send Intuitive Machines Nova-C lander to Vallis Schröteri in Oceanus Procellarum, which is the rill that flows west out of the crater Aristarchus. Gruithuisen Domes had been a potential landing site for Nova-C, and NASA probably did not want to lose an opportunity to go there.

Curiosity spots foot-wide meteorite on Mars

Meteorite on Mars?
Click for original image.

Curiosity appears to have identified a foot-wide rock on the surface of Mars that is likely a meteorite.

While the JPL press release at this link is certain this is a meteorite, the Curiosity science team is properly more circumspect:

The rock we are parked in front of is one of several very dark-colored blocks in this area which seem to have come from elsewhere, and we are calling “foreign stones.” Our investigations will help determine if this is a block from elsewhere on Mars that just has been weathered in an interesting way or if it is a meteorite.

The image to the right surely does look like a meteorite. If so, this would be one of the largest found so far on Mars by any rover.
