Another example of the inability of Democrats to condemn bigotry

2:49 pm

House vote condemning anti-Semitism
Final totals of House vote condemning anti-Semitism.

This column today might sound familiar, as I have reported similar examples numerous times before (See previous essays here, here, here, here, and here). Yet, it is important to document the inability of the modern Democratic Party to unequivocally condemn bigotry, because so much of its base and membership are actually are in favor of such things.

Yesterday the House passed a resolution condemning the horrible rise of anti-Semitism seen nationwide and globally, mostly expressed during pro-Hamas demonstrations that have often descended into violence and calls for the murder of all Jews in Israel.

The resolution [pdf] is quite clear. After listing numerous examples of harrassment and violence against Jews in the U.S., Australia, Israel, and globally, it condemned such behavior, and made it clear that the term “anti-Zionism” is simply a euphemism for anti-Semitism.

The final vote totals are shown in the screen capture to the right, taken from C-SPAN. As you can see, except for one nay vote and four not voting at all, the entire Republican caucus voted in favor of this resolution.

The Democrats however were not so unanimous. While a little less than half of the Democrats in the House voted in support of this amazingly simple resolution, half voted “present”, following the instructions of Congressemen Jerry Nadler (D-New York), Dan Goldman (D-New York), and Jamie Raskin (D-Maryland) (all members of the Democratic Party House leadership). These Congressmen opposed the resolution because it is…

Big Martian gullies partly filled with glacial material

Overview map

Big Martian gullies partly filled with glacial material

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 18, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists dub as “large gullies with infilled alcoves.”

Gullies on Mars were one of the first discoveries by orbiters of small-scalle potential water-caused features on the Red Planet. The favorite explanation for their formation today involves the seasonal freeze-thaw cycle, combined with the deposition of ice and dry ice frost in the winter. When that ice and dry ice sublimates away in the spring it causes collapse and erosion, widening the gullies.

These gullies also exhibit evidence that underground and glacial ice might contribute as well. The material in the largest gullies looks like a mixture of glacial material and dust and debris. It could also be that there is ice impregnated in the ground, which can cause large collapses when it sublimates away.

The white rectangle on the overview map and inset above marks the location of this picture, on the western rim of a 13-mile-wide unnamed crater inside the western portion of the 2,000-mile-long mid-latitude strip on Mars I dub glacier country, since every image from orbit shows evidence of glaciers.

This picture is no different, as the horizontal cracks at the base of the crater rim suggests the glacier that fills the crater floor is being pulled apart by gravity at its edges. The elevation drop from the top of the rim to the floor is about 3,200 feet, so any ice on that slope will definitely be stressed by gravity. Such cracks are therefore not surprising.

Psyche takes its first pictures

9:49 am

The spacecraft Psyche — going to the metal asteroid Psyche — has successfully taken its first pictures, proving its camera and pointing system work as planned.

The pictures, taken on December 4, 2023 from about 16 million miles from Earth, are actually quite boring, merely showing a field of stars. However,

The imager instrument, which consists of a pair of identical cameras, captured a total of 68 images, all within a star field in the constellation Pisces. The imager team is using the data to verify proper commanding, telemetry analysis, and calibration of the images. …The imager takes pictures through multiple color filters, all of which were tested in these initial observations.

At this moment all looks good for Psyche’s eventual arrival at Psyche in 2029.

NASA completes investigation into the failure of the OSIRIS-REx drogue parachute

9:43 am

When the sample return capsule brought OSIRIS-REx’s Bennu samples back to Earth on September 24, 2023, it appeared that the drogue parachute never released prior to the release of the capsule’s main parachutes. Fortunately, those main parachutes were able to do the job, putting the capsule down unharmed but a minute early.

NASA has now completed its investigation into the drogue chute failure. According to its press release:

After a thorough review of the descent video and the capsule’s extensive documentation, NASA found that inconsistent wiring label definitions in the design plans likely caused engineers to wire the parachutes’ release triggers such that signals meant to deploy the drogue chute fired out of order.

The drogue was expected to deploy at an altitude of about 100,000 feet. It was designed to slow and stabilize the capsule during a roughly five-minute descent prior to main parachute deployment at an altitude of about 10,000 feet. Instead, at 100,000 feet, the signal triggered the system to cut the drogue free while it was still packed in the capsule. When the capsule reached 9,000 feet, the drogue deployed. With its retention cord already cut, the drogue was immediately released from the capsule.

In other words, engineers wired the thing incorrectly so it cut its cords before it was released. To further confirm this conclusion engineers will inspect the system thoroughly once scientists have completed removing the Bennu samples from the capsule.

Iran and China complete orbital launches

9:35 am

Iran's launch December 6, 2023
Iran’s Salman rocket lifting off today.
The launch site itself was not disclosed.

According to the official state-run press of each country, both Iran and China yesterday completed successfully launches, both of which appeared to test new capabilities of some note.

First Iran announced that it had used its Salman rocket to put a 500-kilogram capsule that it said was carrying biological samples, and was also “has the ability to carry a human,” though the mass of this capsule makes that highly unlikely. Little other information was provided. Nor has this orbital launch as yet been confirmed by the orbital monitoring services of the U.S. military. The image to the right is a screen capture from the launch video at the link, and appears to show that this rocket has only one stage, thus making an orbital launch impossible.

Assuming this orbital launch is confirmed, it was Iran’s second orbital launch in 2023 and will therefore not show up on the launch race leader board below. If further information is obtained I will update this post appropriately.

China in turn announced the successful launch today of a test satellite, using its new Smart Dragon-3 solid-fueled rocket lifting off from a barge in the South China Sea 1,300 nautical miles off the coast of Guangdong province, where Hong Kong is located. To arrive at this ocean launch location took five days. The launch thus tested the use of this mobile floating platform from remote ocean locations.

The leaders in the 2023 launch race:

89 SpaceX
56 China
16 Russia
7 Rocket Lab
7 India

American private enterprise still leads China in successful launches, 101 to 56, and the entire world combined 101 to 90. SpaceX by itself now trails the rest of the world (excluding other American companies) 89 to 90, though it has another launch planned for tonight, with the live stream here.

December 5, 2023 Zimmerman/Batchelor/Livingston podcast about Apollo 8

9:14 pm

This podcast was specifically to talk about the Apollo 8 mission to the Moon in 1968, and my book, Genesis: the Story of Apollo 8. John Batchelor and David Livingston allowed me to tell a lot of stories, some from the book and some from my private conversations with the astronauts and their families.

Embedded below the fold in two parts.

Note that I will be doing a much longer interview with John Batchelor on the December 23-24, 2023 weekend about Apollo 8 and my book. John scheduled this preliminary short interview so that his weekday audience (different from his weekend audience) could hear about the book.

Pushback: Macy’s sued for its illegal discriminatory hiring policies

3:35 pm

Banned at Macy's
Banned at Macy’s

Bring a gun to a knife fight: The pro-bono non-profit legal firm America’s First Legal (AFL) has filed a federal civil rights complaint against Macy’s for its blatantly illegal diversity and inclusion policies that required hiring quotas bases solely on race.

You can read the complaint here [pdf]. AFL’s letter to Macy’s announcing the complaint is here [pdf]. As noted in AFL’s press release:

In a 2019 press release entitled “Bold Vision To Advance Diversity and Inclusion and Ensure The Company Reflects The Diversity Of The Customers and Communities Served,” Macy’s details its five-point plan with specific directives focused on achieving greater diversity for all aspects of the company’s business model.

The plan explicitly instructs Macy’s management to “[a]chieve more ethnic diversity by 2025 at senior director level and above, with a goal of 30 percent,” as well as to initiate a “12-month program designed to strengthen leadership skills for a selected group of top-talent managers and directors of Black/African-American, Hispanic-Latinx, Native American and Asian descent.” Quotas such as these are patently illegal under the law.

The language of that release is quite appalling. » Read more

Mars Reconnaissance Orbiter takes another look at the non-face on Mars

12:51 pm

The non-face on Mars
Click for original image

In 2007, shortly after it began science operations in Mars orbit, the science team for Mars Reconnaissance Orbiter (MRO) pointed its high resolution camera at the so-called “Face on Mars”, taking a picture that confirmed (as had Mars Global Surveyor several years earlier) that this “face” was a non-face, simply a mesa whose features made it appear roughly facelike in low resolution imagery.

Now, more than sixteen years later, scientists have used MRO to take a new picture of the non-face mesa. That picture is to the right, cropped, reduced, and sharpened to post here. Compared to the 2007 photo the new photo has far better lighting conditions, revealing many details on the mesa’s eastern half that were mostly obscured by shadows previously.

In fact, these new details strongly suggest that the depression on the mesa’s eastern slopes harbors a decaying glacier. At least, that is what the features there resemble.

Ingenuity completes its 67th flight on Mars

9:58 am

Overview map
Click for interactive map.

Almost immediately after communications were re-established with Mars after the monthlong solar conjunction — where the Sun stood between the Earth and Mars — the Ingenuity engineering team uploaded instructions for Ingenuity’s 67th flight, and on December 2, 2023, the helicopter successfully completed that flight, traveling 1,289 feet to the west at a height of 39 feet for 136 seconds, almost exactly what the flight planned dictated.

The overview map above shows with the green dot the helicopter’s new position after that flight. It has moved ahead of Perseverance into Neretva Vallis, the gap out of Jezero Crater through which the rover will eventually travel. At the moment however Perseverance sits much farther east, as indicated by the blue dot, where it has been studying the surface geology of the delta that once flowed through that gap into the crater.
