Scientists: Betelgeuse dimmed because of giant dark spot on surface

12:00 pm

The uncertainty of science: A new study by scientists in China now proposes that the dimming of the red giant star Betelgeuse in 2019-2020 was because of a giant dark and cold spot on its surface.

When Betelgeuse was at its dimmest on Jan. 31, 2020, its effective temperature — meaning, the temperature calculated from its emitted radiation — was measured at 3,476 degrees Kelvin (about 5,800 degrees Fahrenheit or 3,200 degrees Celsius.)

But once the star was back to a normal luminosity, measurements indicated an almost 5% temperature rise to 3,646 Kelvin (roughly 6,100 F or 3,370 degrees C.)

…[T]he astronomers … concluded it is unlikely the entire surface cooled temporarily by that amount. Rather, it must have been a sunspot — or rather, a “star spot” — blocking some of Betelgeuse’s radiation from escaping, they said.

This new hypothesis aligns partly with others that say it was a combination of a dark spot and intevening dust that caused the dimming.

None of these hypotheses however “solve” the mystery. Too little concrete information exists at present to do that.

Perseverance’s first sample grab fails

11:49 am

Perseverance's first core sample drill location
Click for full image.

The first attempt by the Mars rover Perseverance to obtain a core sample has apparently failed.

The failure does not appear to be technical. All the hardware appears to have worked. When they inspected the interior of the hollow core drill however no sample was seen inside.

“The sampling process is autonomous from beginning to end,” said Jessica Samuels, the surface mission manager for Perseverance at NASA’s Jet Propulsion Laboratory in Southern California. “One of the steps that occurs after placing a probe into the collection tube is to measure the volume of the sample. The probe did not encounter the expected resistance that would be there if a sample were inside the tube.”

…”The initial thinking is that the empty tube is more likely a result of the rock target not reacting the way we expected during coring, and less likely a hardware issue with the Sampling and Caching System,” said Jennifer Trosper, project manager for Perseverance at JPL. “Over the next few days, the team will be spending more time analyzing the data we have, and also acquiring some additional diagnostic data to support understanding the root cause for the empty tube.” [emphasis mine]

Do the highlighted words remind you of anything? They do for me. The first thing I thought of when I read this was the drilling mole for InSight’s heat sensor. It failed in its effort to drill into the Martian surface because the nature of the Martian soil was different than expected. It was too structurally weak, and would break up into soft dust rather than hold together to hold the mole in place.

In the case of Perseverance, it appears right now (though this is not confirmed) that the drill successfully drilled into the ground, with its core filling with material, but when the core was retracted, that material simply fell out, as if it was too structurally weak to maintain itself inside the core.

The photo above of the drill hole and its thick pile of dust appears to support this hypothesis. Even though they drilled into what looked like bedrock the act of drilling fragmented that bedrock apart.

I am speculating based on limited information, so I am likely wrong. For example, the drill certainly has sensors to detect the density and structural strength of the rock it is drilling into. The engineers will check those numbers during drilling. If the rock doesn’t appear dense enough or structurally strong enough for a core sample, I would expect them to pick a different spot.

If true however it means that obtaining core samples at many locations in Jezero Crater will simply not be possible. This does not mean no samples will be obtained, because there are definitely places on Mars where the ground’s structure is solid enough for this method to work. Curiosity definitely found this to be true, when if found several places on Vera Rubin Ridge where its drill didn’t have the strength to penetrate the rock.

Having an off day

1:50 pm

To my readers: This is one of those days where I just cannot get up the oomph to write. First, I am becoming bored by my daily “Today’s blacklisted American” column. It is not that the number of people being ruined and harmed by the oppressive thugs of the left has dropped, it is that I am finding that people are becoming desensitized to the oppression. I get the impression that my posts are being skimmed or ignored, because they are merely repeating the same story over and over again.

“Oh, yeah, big deal, another person lost their job because they dared to express an opinion. Call me when something new happens.”

Such a situation I find so depressing words can’t express it. Makes it very hard to work.

Second, I have a bunch of new cool images to post, but I am either waiting for answers from scientists before posting, or I don’t have the mental energy today to work up a post. Sorry. I think I simply need a real day off.

Unless I get energerized later today, you all will simply have to wait until I return in full force on Monday (though if something exciting pops up on the weekend it might get my writing juices flowing sooner).

The trials and tribulations of Blue Origin’s BE-4 engine

12:09 pm

Link here. The article tries to provide some explanations for the delays at Blue Origin that have put the BE-4 engine years behind schedule.

The first and most important fact gleaned from the article is that flightworthy versions of this engine will not be ready this summer as promised, and will likely not get delivered to ULA for its Vulcan rocket before the end of the year, causing its inaugural launch to be delayed to the second half of ’22. This also means that Blue Origin’s own orbital rocket, New Glenn, will likely not launch until late next year, at the earliest.

Moreover, the engines that Blue Origin will deliver to ULA will not be fully tested, and might require replacement if tests on other engines reveal more problems.

The article’s most important revelation about the delays however is this:

One of the most persistent problems, sources said, is that the BE-4 engine testing and development program has been relatively “hardware poor” in recent years. Effectively, this means that the factory in Washington has not had enough components to build development engines, and this has led to extended periods during which no testing has occurred on the stands in Texas.

It was surprising to hear this because back in the spring of 2017 Blue Origin stated publicly that its development program was hardware rich. After arriving as CEO in late 2017, however, [Bob] Smith appears to have focused more on a substantial reorganization of Blue Origin’s leadership rather than hardware development. Other programs were prioritized, too, so the BE-4 team did not get all the resources and freedom it needed to proceed at full throttle. [emphasis mine]

To put it more bluntly, Smith decided it was more important to rearrange the deck chairs rather than launch lifeboats into the water. As a result, Blue Origin has essentially wasted the last four-plus years.

There are signs that the company has changed course away from Smith’s focus, but we shall have to wait and see. The childish press release issued by Blue Origin yesterday, claiming its manned lunar lander was far better than SpaceX’s Starship and should have been chosen by NASA, suggests that the course change has not been as thorough as one would hope. The amount of intellectual dishonesty contained in that release is somewhat disturbing, especially coming from a rocket company:

Blue Origin appears to be, at minimum, cherry picking its comparisons. The graphic notes that the Starship-Super Heavy system hasn’t launched yet. Starship has launched six miles into the air on several occasions, but not with its Super Heavy booster. It also points out that SpaceX’s Starship facilities in Boca Chica, Texas have never accommodated an orbital launch. Blue Origin, though has never launched any rocket to orbit from anywhere.

The graphic doesn’t, however, note the cost of the Starship lunar lander. SpaceX’s proposal estimates that it will cost NASA $2.9 billion, while Blue Origin’s gave a price of $5.9 billion. [emphasis mine]

For the management of a rocket company to not recognize the fundamental facts indicated by the highlighted words above, or to make believe they are unimportant, does not bode well for that rocket company. Rather than focusing on getting its rocket finally off the ground, the management appears instead unwilling to face some hard facts, and fix them.

Meanwhile, SpaceX keeps barrelling along, focused not on petty managment issues or whiny complaints, but on actually building rockets that fly.

Zhurong travels another 700 feet on Mars

11:46 am

Zhurong's location

According to a new update from China’s state-run press today, since the last update of its Zhurong Mars rover on July 31st, the rover has traveled just over 700 feet, for a total travel distance of about 2,624 feet, just under a half mile.

As of August 6, 2021, the rover has worked on the surface of Mars for 82 Martian days and the orbiter has been in orbit for 379 days. The two are in good condition and functioning properly.

The report provides no other real information.. I have indicated on the map to the right the range in which this travel distance could have taken Zhurong. Hopefully they will release more information soon.

The nominal mission was originally planned for 90 days. Right now it looks like the rover will easily exceed that.

SpaceX stacks Starship on top of Superheavy

11:19 am

Superheavy with Starship on top
Click for original image.

Capitalism in space: Only three days after the company had rolled Superheavy prototype #4 to the launchpad, SpaceX today stacked Starship prototype #20 on top, uniting for the first time the entire rocket.

All told, the rocket is 395 feet high, about 32 feet taller than the Saturn-5.

The photo to the right, reduced slightly to post here, was posted by Elon Musk earlier today. It also makes obvious several things that will be different for this Starship flight compared to the previous suborbital hops. Starship’s dark exterior is because it is covered with thermal tiles designed to protect it as it returns to Earth flying through the atmosphere at orbital speeds.

Note also the grid fins on Superheavy. Apparently they will be open during the entire flight, instead of unfurling shortly after stage separation as is done with Falcon 9.

I am not sure what the vertical attachments near the bottom of Superheavy are for. The plan is for the stage to land in the Gulf of Mexico, so it does not need landing legs. Could these be attachment points for holding the rocket to the launchpad?

I have been predicting a late September/early October date for this rocket’s first orbital launch test. SpaceX is sure working hard to beat that timeline. They still need to do tank tests and static fire tests of the whole assembly, but based on past schedules, they might get this done in only a few weeks. If so, it means they might be able to launch before the end of August.

My god, if only other American rocket companies worked in this manner. Imagine what wonders they all could accomplish.

Astra to attempt orbital launch later in August

10:08 am

Capitalism in space: The smallsat rocket company Astra has announced that it will attempt to complete its first successful orbital launch before the end of this month, launching a Space Force satellite.

The U.S. Space Force has booked two missions with Astra, the Bay Area company announced today (Aug. 5). The first flight will launch a test payload for the Department of Defense’s Space Test Program from the Pacific Spaceport Complex in Kodiak, Alaska, during a window that runs from Aug. 27 through Sept. 11.

Astra has two previous test launches that attempted to reach orbit and failed. The second barely missed, because of a fuel mixture issue that had it run out of fuel prematurely.

If successful, this will make Astra the third operational American smallsat rocket company, following Rocket Lab and Virgin Orbit. Four others have promised launches in 2021. By next year the competition in this smallsat launch industry should be quite fierce.

Virgin Galactic reopens suborbital ticket sale, raises price, delays next flight

10:01 am

Capitalism in space: Virgin Galactic announced yesterday that it is resuming ticket sales for flights on its reusable SpaceShipTwo spacecraft, raising the price from the old price of $250,000 to a new price of $450,000.

Virgin Galactic is offering customers three options: purchase a single seat, buy several together or book an entire flight on the eight-passenger Unity (or other space planes that come into operation, such as the recently built VSS Imagine). The company also sells seats for microgravity research and professional astronaut training. Those are in a different tier, going for $600,000 apiece, Colglazier said during a call with investors on Thursday afternoon.

The announcement also revealed that they are delaying their next flight until September. That flight has been scheduled for the summer for months. The company is also delaying the start of regular commercial flights until late in ’22, in order to make some upgrades to their spacecraft.

By that time, regular orbital tourist flights will have become almost routine. Moreover, one has the option to experience weightlessness for far less buying a ticket on one of the various companies that fly “vomit comet” airplanes.

One wonders if the demand for these flights will be sustainable. We shall see.

China launches military communications satellite

9:48 am

China’s Long March 3B rocket yesterday successfully launched a military communications satellite.

This was China’s eighth government launch since the beginning of July, in a span of only five weeks.

The launch was from an interior spaceport, so the rocket’s strap-on boosters and first stage core landed within China. No word if any landed near or on habitable areas, or if the Chinese were using parachutes or grid fins to control their landing.

The leaders in the 2021 launch race:

26 China
20 SpaceX
12 Russia
3 Northrop Grumman
3 Rocket Lab

The U.S. still leads China 30 to 26 in the national rankings.

Ingenuity successfully completes 11th flight

1:14 pm

Ingenuity about to land
Click for full image.

Ingenuity has successfully completed its 11th flight, safely touching down at approximately its planned landing spot. From the science team’s tweet:

[Ingenuity] has safely flown to a new location! Ingenuity flew for 130.9 seconds and traveled about 380 meters before landing.

The image to the right, reduced to post here, was taken mere seconds before landing, and shows the helicopter’s shadow directly below it on the ground.

This particular flight was the first that did not push Ingenuity’s abilities, merely flying in a straight line to put it in a good position for later flights and to keep it ahead of Perseverance.

So far they have only released five images from the flight. Expect the rest to be downloaded from Perseverance in the next few days.

As thousands of teachers endorse critical race theory, home schooling surges

What apparently Critical Race Theory sees as education for
elementary school kids.

In the past few months state legislatures across the country have passed resolutions that ban schools from teaching the Marxist and bigoted program dubbed Critical Race Theory (CRT).

Not surprisingly, the leftists who dominate our school systems have fought back. The very leftist Zinn Education Project immediately created a petition calling for teachers to defy such laws and to continue to teach CRT, which teaches children to hate whites and to give minorities privileged status.

In the two months this petition has been on line almost 6,000 teachers have signed it, with many adding comments of defiance. This one is typical:

Curiosity: Nine years since landing on Mars and the way forward

The way forward for Curiosity
Click for full image.

In today’s Curiosity update written by planetary geologist Abigail Fraeman, she noted this significant fact:

Project scientist Ashwin Vasavada pointed out a great fact at the beginning of planning today: At around 4 o’clock in the afternoon on Sol 3199 (the first sol in the plan we are creating today), Curiosity will begin its 10th Earth year on Mars. In the last nine years, the rover has traveled 26.3 km [16.3 miles], climbed over 460 m [1,509 feet] in elevation, and collected 32 drilled samples of rock.

Her update includes the first image taken by Curiosity upon landing, a view of Mount Sharp using the rover’s front hazard camera. In that picture, the mountain is far away, as the rover was sitting on the flat floor of Gale Crater.

The photo above, cropped and enhanced to post here, was taken yesterday by one of Curiosity’s navigation cameras, and looks out across the rocky mountainous terrain the rover is soon to travel. As Fraeman also notes,

Details on the Russian movie to be shot on ISS in October

9:13 pm

Link here. The article provides a lot of details about who will fly, who will do what, and who is slated as back-ups if the primary crew of actress and director fail their training. However, I found the description of the movie to be the most interesting thing:

Shipenko revealed the script is still being fine-tuned, but the plot involves a cosmonaut who suffers a cardiac arrest during a spacewalk and, although he survives, he will require surgery to ensure he can handle the Soyuz return to Earth. A female cardiac surgeon, named Zhenya, has to be sent to the ISS to perform the procedure with only a few weeks to prepare for the trip.

Unlike the American space films like Gravity, this story is incredibly well grounded in reality. The Russians have actually experienced examples of station astronauts getting so sick in space that their missions had to be aborted early. In one case it was a prostate infection. In another it was the mental illness of the entire crew.

This story is also comparable to situations that have occurred in Antarctica, a very similar environment to the station. In the early 2000s the doctor in Antarctica had to perform surgery on herself because she had developed cancer. Then in 2016 Buzz Aldrin had to be evacuated due health issues.

If done right, this could not only make a damn good movie, it will also do so by revealing the true dangers of going to space.

Seven Brides for Seven Brothers – Lonesome Polecat

6:01 pm

An evening pause: This song, from the 1954 MGM classic musical, was one of the first evening pauses I posted back in 2010. As Diane and I recently rewatched the musical, I think it time to repost it. As I said then,

This haunting song from the movie Seven Brides for Seven Brothers is notable not only because of the beauty of the music and dancing, but because the entire number is shot as one take, no cuts. Everyone, from the actors with their axes to the crew moving the camera on its dolly and crane, had to be right on cue for everything to work.

Having spent almost twenty years in the movie business, I can promise you that this is not easy.

The 2010 evening pause uses the original voice of red-haired Matt Mattox, which was dubbed for the movie.

White blobs on Mars

White blobs on Mars
Click for full image.

Time for another “What the heck?” image. The photo to the right, cropped to post here, was taken on May 18, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what appears to be a series of white circular features aligned with a ridge line.

Are these eroded craters? Maybe, but their alignment with those ridges suggests otherwise. If you look at the full image, you will see further parallel ridges to the north and south, also with similar circular blobs lined along them. Furthermore, the flat surrounding terrain, part of the northern lowland plains north of the resurgences from Valles Marineris, has a scattering of very normal looking craters, with distinct rims and even some glacial material within. As this is at 44 degrees north latitude, the presence of glacial material inside craters is not surprising.

Thus, the white blobs are likely not craters, but some form of eruptive material from below, coming up along those ridges which are probably faultlines. The whiteness suggests that material is water ice, but this of course is unconfirmed.

The question is of course, why? What would cause water ice to erupt along these faultlines? And why are such features not seen elsewhere? Faults and underground ice are common on Mars. Yet, I don’t remember seeing features such as this in any other Martian images.

Today’s blacklisted American: Cybersecurity experts want people fired for expressing unpopular opinions on line

1:09 pm

1966 in communist China
Mao’s cultural revolution in 1966, what the leftists
at Respect in Security want for America and the world.

Persecution is now cool! A new project being developed by leftist cybersecurity experts calls for corporations to use their software to identify and fire individuals that their software identifies as having expressed what they define as “offensive” speech online.

Cancel Culture and Big Tech are a match made in hell, as cybersecurity experts call to target the livelihood of internet users who get too edgy online. “The initiative, called Respect in Security, was launched on Tuesday by two cybersecurity experts. According to the founders, several companies have already signed up,” Reclaim The Net reported. “For a lot of people, it’s a no man’s land,” founder Lisa Forte and Red Goat Cyber Security employee told the BBC. “It can feel like the platforms do nothing, the police don’t do a lot, lawyers are expensive and the publicity legal action generates can be negative.”

The BBC reported that co-founder and Trend Micro Vice President Rik Ferguson said “many companies had anti-bullying policies but they tended to focus on internal behaviour.” In what may be a reference to his Respect in Security program, he wrote a few weeks ago: “Inside my ‘Projects’ email folder resides a subfolder called ‘Kill Trolls’ and it is now only a couple of weeks away from becoming a real thing (sadly not with that name).”

Free speech advocates concerned about Ferguson and Forte’s work may have good reason to be. Forte explained her clear fix for people saying offensive statements via the internet: “The best solution we have, if the culprit is identifiable, is to approach their employer.” [emphasis mine]

It is bad enough that the big social media companies — Google, Facebook, Twitter — are routinely banning conservatives for expressing opinions or even facts they don’t like. Now the storm troopers above want to extend the blacklisting to get those same people fired for daring to speak their mind publicly. From another story:

Ingenuity’s 11th flight scheduled for tonight

10:24 am

Ingenuity's 11th flight plan
Click for interactive map.

The next flight of Ingenuity on Mars is now scheduled for this evening, and will be a much simpler flight than the helicopter’s previous trip.

The map to the right shows the route in blue. The flight is mainly a transfer flight, intended to keep the copter ahead of the rover as they leapfrog from point to point in Jezero Crater. It will actually be the first flight by Ingenuity that does not push its engineering in any major way.

This map, the most up-to-date available, is at this moment about five sols out of date. Perseverance is likely slightly south and to the west of the location shown.

The present plan is for Perseverance to travel to the northwest along the dark ridgeline that Ingenuity will land next to. The rover will then retreat, returning more or less to its landing area and then north to circle around the largest crater on the map and then to head west to the base of the delta to the area labeled “Three Forks”, which is their entrance to the delta’s geology.

Gil Levin passes away

9:48 am

Gil Levin, a instrument project scientist for one of the science experiments on the Mars Viking landers in the 1970s, has passed away at 97.

Levin deserves special mention because he believed for years that his experiment, called “labeled release,” had possibly found evidence of life.

Dr. Levin’s experiment employed a nine-foot arm to scoop Martian soil into a container, where it was treated with a solution containing radioactive carbon nutrients. Monitors detected the release of radioactive gas, which Dr. Levin interpreted as evidence of metabolism.

“Gil, that’s life,” Straat said when they saw the results.

The findings held true for both Viking 1 and Viking 2, which took samples from different regions of the planet. Other experiments aboard the Viking, however, used different methods to conclude that Martian soil did not contain carbon, an element found in all living things.

Dr. Levin stood by his findings, but top NASA scientists disagreed, saying that the response he observed was the result of inorganic chemical responses, not biological processes. “Soon thereafter,” Dr. Levin told the Johns Hopkins University School of Engineering Magazine last year, “I gave a talk at the National Academy of Sciences saying we detected life, and there was an uproar. Attendees shouted invectives at me. They were ready to throw shrimp at me from the shrimp bowl. One former adviser said, ‘You’ve disgraced yourself, and you’ve disgraced science.’”

I met Levin once and interviewed him several times. With amazing grace and cheerfulness he always emphasized that his results needed to be confirmed, and there was certainly room for skepticism, but to reject them outright was not how the scientific method worked.

Levin however was never awarded another NASA project, essentially blackballed because of his 1970s claims, even though later research hinted at the possibility that he may have been right.

R.I.P. Gil Levin. Though the overall data we have gotten from Mars in the half century since still favors a non-life explanation for his experiment, the uncertainty remains quite large. He could have been right.

More important than his uncertain result, however, was his dedication to the proper scientific method, where you let the data speak for itself and never dismiss any possibility if that is what the data shows you.

Lemon Pipers – Green Tambourine

Superheavy prototype #4 rolls to orbital launchpad

2:51 pm

Superheavy #20 on the way to launchpad

Superheavy on launchpad
Click for live stream.

Capitalism in space: SpaceX today rolled its 4th Superheavy prototype from its assembly building in Boca Chica, Texas, moving it to the orbital launchpad in preparation for having the 20th Starship prototype stacked on top and assembled for the rocket’s first orbital test flight.

The first image to the right is a screen capture taken from a short movie posted in an Elon Musk tweet. It shows the base of this Superheavy, with its 29 Raptor engines. The engines appear surrounded by the support structure that holds the stage to the truck mover.

The second image to the right is a screen capture from Labpadre’s live stream Saphire camera, captured shortly before this post was published. Superheavy is 230 feet tall. Starship is 165 feet tall. Combined that equals just under 400 feet, which is still about 30 feet taller than the Saturn-5.

Yet, Superheavy is easily dwarfed by the launch tower behind it, and when they stack Starship on top the combined rocket will still be only three quarters as tall as the tower. They are using that tower not only for launches, but for stacking of Starship as well as a capture devise for when later Superheavies return to Earth. Instead of having landing legs, Superheavy will eventually lower itself into position next to the tower and hover there so that the tower can grab it.

All this means the tower needs to be taller than the combined rocket. I would also expect that a second tower will be necessary eventually for that landing grab.

Before they stack Starship #20 on top they will likely do pressure and tank tests of Superheavy, and maybe a few dress rehearsal countdowns leading to short static fire tests.

It still appears to me that we are looking for an orbital test flight sometime in late September, early October.

Chinese pseudo-private rocket fails during launch

2:23 pm

A launch attempt by the pseudo-private Chinese company iSpace failed today, the second failure in a row for this company following a success.

A Hyperbola 1 rocket lifted off from the Jiuquan launch base at 3:39 a.m. EDT (0739 GMT; 3:39 p.m. Beijing time), China’s government-run Xinhua news agency said. Xinhua, which described the launch as a “flight test,” said the rocket exhibited “abnormal performance” after liftoff. Officials did not immediately specify when during the flight the rocket failed.

The news agency said a satellite carried by the rocket “did not enter orbit as scheduled.” Chinese officials did not identify the payload lost on the mission.

This is the second launch failure in a row, following the first successful orbital launch in July 2019.

The rocket is made of four solid-fueled stages, which means it most certainly is using military tecnology and is being closely supervised by the Chinese government. ISpace is one of about four such pseudo-private Chines companies. In each case, China is allowing private Chinese capital to finance the development of these rockets, for use both by the Chinese government as well as sale to customers (but only with the government’s approval and control).

Curiosity’s wheels: a good news update

11:13 am

Curiosity's wheels
Click here and here for the original images.

For the past few weeks Curiosity has been traveling across some of the roughest terrain it has seen on Mars, since landing in Gale Crater in August 2012. The rover is now roving among the high cliffs and foothills at the very base of Mt Sharp, with the ground covered with rocks, boulders, plates of bedrock, and all sorts of protrusions.

On August 1st the rover team used its cameras to do another survey of the rover’s wheels to see how they fared during that journey. The two images to the right compare the same area on the same wheel after the most recent 16 sols of travel. This is the same wheel I have focused on since 2017. Overall, the damage in the most recent picture seems almost identical to the previous picture. In fact, if you compare today’s image with the annotated version of the 2017 photo, found here, you can see how little things have changed since then.

From this one wheel it appears that the wheels are continuing to hold up quite well. The Curiosity team of course needs to review all the images of all the wheels, but based on this one comparison, it looks like their long term strategies for mitigating damage to the wheels is working, even in the rough terrain the rover is presently traversing.

The annual July fund-raising campaign: Thank you!

10:05 am

This post will remain at the top of the page for the next few days. Scroll down for news updates and commentaries.

My July fund-raising campaign for 2021 has now ended. Thank you all for your donations and subscriptions. While this year’s campaign was not as spectacular as last year’s, it was the second best July campaign since I began this website. My gratitude cannot be expressed adequately.

As already mentioned, a handful of people have donated enough for a free ebook, but have not responded to my requests for which book they wish and in what format. I can’t give you this gift if you don’t tell me what you want. Will those individuals please email me the book and the format (epup or pdf) they desire?

I once again must express my gratitude to everyone for their support. No one is obliged to pay anything to read my website. That so many people are willing to give freely warms my heart, and gives me hope that I am not the only person left who believes in fearless exploration and freedom.

The photo to the right, rotated, cropped and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) more than a decade ago, on June 1, 2010. I post it now because it is today’s MRO picture of the day, and is definitely cool. The caption:

One of a few “scaly-looking” inselbergs within regional platy-ridged flows in Elysium Planitia. This inselberg has a broken and blocky appearance with some of the blocks being tilted. Could this be the remnant of a once extensive mantling deposit? An inselberg is an isolated hill or mountain rising abruptly from a plain.

The wider image by MRO’s context camera below, also rotated, cropped and reduced to post here, illustrates even more forcefully how isolated this circular set of blocks is.
