Peggy March – I Will Follow Him
An evening pause: This live television performance from sometime in the 1960s, and was almost certainly performed by lip-sync to the recorded album. That audio for this video has been remastered.

Twisted taffy in the basement of Mars
Click for full image.
Cool image time! The photo to the right, taken on March 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and cropped and reduced to post here, shows us an example of one of Mars’ strangest and most puzzling geological features, dubbed banded or “taffy-pull” terrain by scientists.
Taffy-pull terrain has so far only been found within Hellas Basin, Mars’ deepest impact basin and what I like to call the basement of Mars. Because of the lower crater count in this terrain scientists consider it relatively young, no more than 3 billion years old, according to this 2014 paper, which also notes
The apparent sensitivity to local topography and preference for concentrating in localized depressions is compatible with deformation as a viscous fluid.
At the moment what that viscous fluid was remains a matter of debate. Many theories propose that ice and water acting in conjunction with salt caused their formation, similar to salt domes seen on Earth. Other propose that the terrain formed from some kind of volcanic or impact melt process.
Almost all of the taffy terrain on Mars has been found in the deepest parts of Hellas Basin in a curved trough along its western interior, as shown by the light blue areas in the overview map below.

Today’s blacklisted American: Student is persecuted by university for asking a question
No longer exists at the University of Virginia
They’re coming for you next: Because medical student Kieran Bhattacharya dared to question the scientific validity of the term “microaggressions” during a panel discussion, the University of Virginia’s School of Medicine began an investigation that accused Bhattacharya of being a threat to others and banned him from the campus.
Here was what the student said.
“Thank you for your presentation,” said Bhattacharya, according to an audio recording of the event. “I had a few questions, just to clarify your definition of microaggressions. Is it a requirement, to be a victim of microaggression, that you are a member of a marginalized group?”
Adams replied that it wasn’t a requirement.
Bhattacharya suggested that this was contradictory, since a slide in her presentation had defined microaggressions as negative interactions with members of marginalized groups. Adams and Bhattacharya then clashed for a few minutes about how to define the term. It was a polite disagreement. Adams generally maintained that microaggression theory was a broad and important topic and that the slights caused real harm. Bhattacharya expressed a scientific skepticism that a microaggression could be distinguished from an unintentionally rude statement. His doubts were well-founded given that microaggression theory is not a particularly rigorous concept.
You can listen to the audio of this exchange here, beginning at about 28 minutes. Bhattacharya is respectful and calm, and is asking legitimate questions. It appears his main concern was the blanket vagueness of the term that allows anyone to claim a microaggression for almost any statement or act.
Apparently, the organizers of the event then decided that his questions were a microaggression in themselves, for which he must be punished.

Apollo 11 astronaut Michael Collins has passed away at 90
R.I.P. Michael Collins, the astronaut on Apollo 11 who stayed in lunar orbit while Neil Armstrong and Buzz Aldrin walked on the Moon, passed away today at the age of 90.
Collins was one of the most friendly and personable astronauts I ever met. He was always available and willing to answer questions, sometimes even willing to go an extra mile to provide you more than you asked for.
In many ways his later work as head of the Air & Space Museum was more important than his time as an astronaut. He helped make that museum and the history it documents one of the most popular in the world.
As long as humanity exists, on Earth and in space, Michael Collins will never be forgotten.
Perseverance as seen by Ingenuity
Click for full image.
Cool image time! JPL today released the photo to the right, cropped to post here. It was taken by the helicopter Ingenuity during its third flight on April 25th and shows the rover Perseverance at its left edge.
The horizon is tilted because the camera lens is very wide angle to capture as much terrain as possible and thus produces a fisheye curved distortion to the image’s periphery.
This image was taken as Ingenuity flew north about 160 feet away from Perseverance, probably in the first part of its flight as seen by photos taken by Perseverance of Ingenuity during its flight.
The mountains in the distance are the rim of Jezero Crater.

Dynetics has joined Blue Origin in protesting Starship contract by NASA
Capitalism in space? Dynetics today joined Blue Origin in protesting NASA’s decision to award SpaceX the sole contract for building a manned lunar lander, using its Starship spacecraft.
Though the company’s protest did not going into specifics, it appears that Dynetics main complaint is the decision to not award two companies a contract, as originally planned. Even so, these factors make Dynetics bid quite problematic:
Of the three bidders, Dynetics was the lowest ranked. It had a technical rating of “Marginal,” one step below the “Acceptable” that Blue Origin and SpaceX received. Its Management rating of “Very Good” was the same as Blue Origin but one step below SpaceX’s “Outstanding.”
In the source selection statement, Kathy Lueders, NASA associate administrator for human exploration and operations, said the Dynetics lander “suffered from a number of serious drawbacks” that increased risk. The lander was overweight, which at this early stage of development “calls into question the feasibility of Dynetics’ mission architecture and its ability to successfully close its mission as proposed,” she wrote. The evaluation also questioned the maturity of the technology for performing in-space cryogenic fluid transfer required to refuel the lander, as the company planned.
Lueders concluded that “while Dynetics’ proposal does have some meritorious technical and management attributes, it is overall of limited merit and is only somewhat in alignment with the objectives as set forth in this solicitation.” The document only stated that Dynetics’ proposal had a price “significantly higher” than Blue Origin’s proposal, which in turn was significantly higher than SpaceX’s winning bid of $2.89 billion. Blue Origin disclosed in its protest that it bid $5.99 billion. [emphasis mine]
So, Dynetics proposed to build an overweight lander and do it at the highest price. If anything this protest enhances Blue Origin’s protest. It certainly doesn’t do much for Dynetics.
In fact, a good metaphor for the bidding here would be to imagine three vacuum cleaner salesman arriving at your door, all at the same time. One salesman, Mr. Newbie Dynetics, offers you a vacuum cleaner (as yet unbuilt in any form) that as presently designed will only be able to suck in about two-thirds of the dirt on your floor, and demands you pay $800 for it. The second salesman, Jeff “Blue” Origin, says his design (also unbuilt) is far better because they’ve done some successful tests of a tiny handheld prototype, and in addition he’ll only charge you $599 for it.
Neither Newbie or Jeff have any financing, so you will have to foot the entire bill.
The third salesman, Elon Starship, shows up with a full size prototype that while it has some problems, actually functions, and has been tested a number of times already. He also has more than two thirds of his development already financed by others, and only wants to charge you $289.
Who would you pick?
Since I know my readers are neither elected officials nor government officials in Washington and therefore know how to use their brains intelligently, I suspect I know.
We shall soon find out just how smart or dumb those elected officials or government officials in Washington really are.
Martian pit on top of Martian dome
Click for full image.
Cool image time! The photo to the right, cropped and reduced to post here, was taken on March 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and was simply labeled “Pit on Top of Dome in Promethei Terra.”
The cropped section to the right shows one of two such pits visible on the entire image. Promethei Terra is a large 2,000 mile long cratered region due east from Hellas Basin, the deepest large region on Mars.
What caused these pits? The known facts provide clues, but do not really solve the mystery.
First, this image is located in the southern cratered highlands at 45 degrees south latitude. Thus, it is not surprising that it resembles similar terrain in the northern lowlands that suggests an ice layer very close to the surface.

Today’s blacklisted American: Any business in a Massachusetts town that does not genuflect to BLM and its Marxist agenda
Witch burning returns to Massachusetts!
The worst horror of the new leftist blacklisting that is sweeping America is how pervasive it is. This intolerance for dissent is not limited to a small number of people leading the way, but seems to instead be springing upward from that movement’s grass roots.
Today’s blacklist story illustrates this quite starkly.
In the small town of Sturbridge, Mass., a group of 200 left-leaning citizens organized on Facebook to compile a list of businesses to avoid due to insufficient wokeness. The group even planned to present every local business with a pro-Black Lives Matter statement to sign — or face a local boycott.
When the website Turtleboy Sports published that list in full, the woman who created it, Sarah Prager, as well as the administrators of that private Facebook group, Amanda Ivey and Chelsea Ann, then apparently claimed (along with others from that group) that it was merely an internal document not meant for public viewing. They also justified its existence by saying it was not a blacklist but a list of all businesses in town, and had been designed merely to record the political leanings of each so that people would know which businesses had bad political leanings and could be properly avoided. Here are some examples, as noted by Turtleboy:

Starship prototype #15 completes static fire test
Capitalism in space: SpaceX’s fifteenth Starship prototype successfully completed a static fire test yesterday, and the company is now hoping to do its first test flight this week, possibly as early as tomorrow.
Meanwhile, preparations continue for the first test launch of a Superheavy prototype, as well construction at Boca Chica of the orbital launchpad.
The Orbital Launch Site is a hive of activity, with work ranging from the installation of large GSE (Ground Support Equipment) tanks to continued work on the launch mount and launch and integration tower.
The latter has now started to rise into the air next to the mount, which is yet to receive its launch table.
When finished, the tower will be the tallest structure in the region, at nearly 152 meters — towering over the 120 meter tall, fully integrated Starship/Super Heavy stack. The Tower will eventually host a crane and, as crazy as it initially sounded when Elon revealed it, arms designed to catch the returning booster.
It is not yet clear what the test schedule for Superheavy will be leading to that first orbital launch. They will likely fly a prototype on a hop first, then fly it with Starship stacked above. SpaceX however has not said exactly what its plans are, and even if it had, the company has been quite willing to revise those plans should it decide a change is advisable.
The commercial history of Russia’s Proton rocket
Doug Messier at Parabolic Arc today published a detailed launch history of Russia’s Proton rocket, outlining its commercial rise beginning in the 1990s and its fall in the 2010s with the arrival of SpaceX.
The fading of Proton reflected strong competition from SpaceX’s reusable Falcon 9 rocket, which captured an increasing percentage of commercial launches with significantly lower prices.
There was also a global shift away from Proton’s bread and butter, the geosynchronous communications satellite, toward large constellations deployed into low and medium Earth orbits.
Proton’s reputation was also damaged by serious quality control problems that affected the entire Russian launch industry. Proton suffered 9 launch failures and one partial failure in the 10 years between 2006 and 2015. The booster was left grounded for as long as a year at a time. Insurance rates for Proton flights soared.
Proton appears to still have six launches on its manifest, but the shift in Russia to its Angara rocket likely means the end of Proton’s long history, begun at the very beginnings of the space age in the 1960s, is in sight.
SpaceX leases bigger space at LA port for processing Falcon 9 boosters after launch
Capitalism in space: According to the mayor of Los Angeles, SpaceX has signed a new lease for more space at the city’s port, taking over the facilities no longer used by Sea Launch’s floating launch platform that is now in Russia.
News of the port lease broke on April 26th with a tweet from the mayor of Long Beach, California after the Port of Long Beach (POLB) Commission voted to approve SpaceX’s 24-month sublease with an effective start date of May 1st, 2021. From 2014 to 2020, a massive floating rocket launch complex and associated service ships once used by SeaLaunch called POLB’s Pier 16 home while mothballed and the company left behind a decent amount of infrastructure when it vacated the facility last year.
That includes a ~5600 square meter (~65,000 sq ft) warehouse and office space formerly used to process SeaLaunch payloads and Ukrainian Zenit rockets, as well as a pier and dock space generally optimized for loading and unloading large rockets from rocket transport ships. In other words, Pier 16 is a perfect fit for SpaceX’s needs.
SpaceX has twice before signed similar leases and then canceled them. Now it appears the deal is more firm, as the company appears to be gearing up for regular Starlink satellite launches from Vandenberg, requiring a bigger need in LA for processing Falcon 9 first stage boosters after launch.
I wonder too if this deal might be in connection with Starship and the two used floating oil rigs that SpaceX now owns and is refitting as Superheavy/Starship launch and landing pads. This LA facility would be ideal for these ocean platforms before and after launch.
