Curiosity's view across Gale Crater
Click for full image.

Most of the images from Curiosity that I have posted recently have been of the spectacular mountain scenery looking south at Mount Sharp itself. Today’s cool image, taken on July 6, 2021 by the rover’s right navigation camera and cropped to post here, instead looks north, out across the floor of Gale Crater to its distant rim about twenty miles away.

The rover is likely not to move for a week or so, as it has just completed drilling its first drillhole since it moved up into the next geological layer, dubbed the sulfate unit. Because of this they have been using the rover’s cameras to take a lot of pictures of the surrounding terrain, including several high resolution mosaics.

The two overview maps below show what the cool image above is looking at.

Engineers successful complete simulation of Hubble repair

12:30 pm

Though the details released are sparse, engineers working to get the Hubble Space Telescope back in operation since it shut down due to a computer problem in mid-June report today that they have successfully completed a simulation of the procedures they need to do to fix the problem.

This is their entire report:

[The engineers] successfully completed a test of procedures that would be used to switch to backup hardware on Hubble in response to the payload computer problem. This switch could occur next week after further preparations and reviews.

Apparently, because the switch to backup hardware requires switching more than one unit, the sequence is important and following it correctly is critical. It appears they have now determined the correct sequence and will attempt it on Hubble next week.

Today’s blacklisted American: Facebook to punish users who link to peer-reviewed science it dislikes

12:21 pm

Modern science!
How Facebook applies science.

Blacklists are back and Facebook’s got ’em! Facebook is now warning its users that it will punish them if they repeatedly link to peer-reviewed science papers that document the long known harmful effects from improper mask use.

Facebook is warning users against sharing a study that found dangerously high carbon-dioxide intake in masked schoolchildren, published in the Journal of the American Medical Association (JAMA) Pediatrics. “Pages and websites that repeatedly publish or share false news will see their overall distribution reduced and be restricted in other ways,” the warning says when users paste the link on Facebook, before confirming they want to share it.

It’s giving the same warning and threat of account restrictions to users who paste a link to Townhall.com article on a University of Florida lab that found dangerous pathogens on children’s face masks, submitted for testing by their parents. [emphasis mine]

Apparently, Facebook’s “‘fact-check’ simply highlight[ed] disagreements between the scientist who conducted the test and other scientists who did not conduct the test. … Instead of acknowledging that more study would resolve the dispute, [Facebook] call[ed] the report false. That’s not science — that’s propaganda.”

The second study about the number of very bad pathogens that gather on masks used during a single day was already discussed by me in an earlier post. That study found that after a single day of use,

Problems with Blue Origin’s engine force more delays of ULA’s new Vulcan rocket

10:28 am

In a detailed and very informative review of the partnership between ULA and Blue Origin yesterday, Eric Berger at Ars Technica noted these unfolding facts:

For years, United Launch Alliance chief executive Tory Bruno had been saying the new Vulcan rocket, powered by two [Blue Origin] BE-4 engines, would launch in 2021. However, he recently told Aviation Week the first launch would slip into 2022. Bruno said this was due primarily to the mission’s customer, Astrobotic, whose Moon lander was not ready. Technically, Bruno said, Vulcan still had a chance to be ready for a 2021 launch.

This seems highly unlikely because it is already July, and United Launch Alliance (ULA) still does not have a pair of flight engines. After receiving the flight engines from Blue Origin, ULA needs to attach them to the Vulcan rocket, roll it to the launch pad, and conduct a lengthy series of tests before a hot-fire ignition. After this hot-fire test, the rocket will be rolled back to the hangar and prepared for an actual launch attempt. As of January, Bruno was saying this hot fire test with the flight engines would take place this summer. That will no longer happen.

In December both companies promised delivery of those flight engines by this summer, but so far nothing has arrived. Moreover, both companies have remained very tight-lipped about the cause of the most recent delays. In October 2020 Bruno said that an issue with the engine’s turbopumps had been identified and fixed, but if so why has the engine not arrived as promised?

A GAO report released last month had described issues with the engine’s “igniter and booster capabilities,” but Bruno himself has denied the igniter was a problem.

Regardless, Blue Origin’s inability to deliver this engine is causing problems at both companies. Both have been forced to delay the launch of their new orbital rockets. Both rockets were initially scheduled to launch in 2020, were delayed to 2021 about two years ago, and now are likely not to launch until 2022.

While ULA can still switch to its Atlas 5 rocket for some planned Vulcan launches (and has already done so), that rocket is more expensive and thus eats into the company’s profit margin. Using the more expensive Atlas 5 in bidding also makes it more difficult for ULA to compete with SpaceX in any head-to-head competition.

Blue Origin does not even have this option. Its proposed New Glenn rocket is grounded until it gets its engine operational.

All told, the failure of Blue Origin to deliver here is essentially grounding all of SpaceX’s potential American competition, a situation that is not healthy for the American rocket industry.

Update on Ingenuity’s 9th flight

9:55 am

Ingenuity's 9th flight
Click for interactive map

Ingenuity’s engineering team late yesterday posted an update on the helicopter’s successful 9th flight on July 5th, describing in detail the changes they made to their software that made the challenging flight possible.

The changes were required because the helicopter flew for the first time over much rougher terrain then initially planned, as shown by the map to the right.

Flight 9 was not like the flights that came before it. It broke our records for flight duration and cruise speed, and it nearly quadrupled the distance flown between two airfields. But what really set the flight apart was the terrain that Ingenuity had to negotiate during its 2 minutes and 46 seconds in the air – an area called “Séítah” that would be difficult to traverse with a ground vehicle like the Perseverance rover. This flight was also explicitly designed to have science value by providing the first close view of major science targets that the rover will not reach for quite some time.

In other words, Ingenuity flew for the first time over terrain that Perseverance cannot drive to, recording images from above of surface features beyond the rover’s range.

We began by dipping into what looks like a heavily eroded crater, then continued to descend over sloped and undulating terrain before climbing again to emerge on a flat plain to the southwest.

The images of that rough terrain have not yet been downloaded to Earth, but will be in the next week.

Loudon Wainwright – One-man Guy

6:01 pm

An evening pause: I first posted this as a pause back in 2012. Time to post it again, as I empathize with Wainwright even more now than then.

We all travel a path in life. Once Americans celebrated those who chose an independent and unique path. That no longer appears true, not that it would make any difference to Wainwright, or to me. For some, to chose a unique path and be true to yourself is the only option.

Enrollment in public schools plunges

2:42 pm

Good news! Federal government data for the 2020-2021 school year shows a steep drop in enrollment in public schools, with the biggest declines in the youngest grades.

While overall the drop was only 3%, the drop was stunning from parents enrolling their children for the first time.

Even more stark is the drop in enrollment among younger students. Preschool enrollment fell by 22%, and preschool and kindergarten enrollment combined dropped 13%.

The drop is even more significant in that it is really the first such decline in decades.

It appears that almost one in four parents have decided that public schools are not a good place for their little ones. Foolish mask mandates, absurd social distancing rules, and leftist propaganda promoting bigotry and sexual perversity are not what they want for their kids.

In a sane world, we would quickly see a reduction in the budgets for these public schools. Sadly this is not likely. Too many local politicians are under the thumb of the teacher unions, and serve them, not their constituents.

In the end however these budgets must be cut, if not entirely zeroed out. As long as the money keeps flowing to these corrupt institutions, they will have power and will use it for bad ends.

Let me add one more point: Considering the horrible state of the public schools, their mistreatment of children in connection with COVID, their failure to teach anything well in the past few decades, their new endorsement of racial bigotry and hatred, and their increasing partnership with radical sexual perversity, I must ask: Why on Earth are 78% of parents still sending their kids there?

Springtime on Martian dunes near the north pole

1:42 pm

Dunes near the Martian north pole, in the spring

Cool image time! The photo to the right, rotated and cropped to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on April 27, 2021. It shows a strange scattering of dunes on a flat plain. The red at the top of each dune probably indicates exposed dust and sand. The white fringe is likely either water frost or the leftover mantle of dry ice that is deposited in the polar regions each winter down to 60 degrees latitude, and disappears with the coming of spring, sublimating back into carbon dioxide gas.

There are a lot of puzzles here. The overview map below provides some context, but only some.

Today’s blacklisted American: Students demand blacklisting of university trustee because he donated to Trump’s campaign

1:00 pm

The Bill of Rights cancelled by students at Northwestern University
No first amendment permitted at Northwestern
University, if the students have their say.

Blacklists are back and the students at Northwestern U have got ’em! The student government at Northwestern University in Illinois recently passed a resolution demanding that the school’s board of trustees remove trustee J. Landis Martin from the presidential search committee because he had the gall to donate to Trump’s presidential campaign.

On June 2, student government members approved a resolution to remove J. Landis Martin, Chairman for the Northwestern University’s Board of Trustees, from the Presidential Search Committee, which is reported to be choosing the next Northwestern University President within the next year, according to the Daily Northwestern.

Outlined in the “Resolution for the Recusal of J. Landis Martin from the Presidential Search Committee” are the reasons the student government voted 17-1 to dismiss Martin on June 2nd.

The resolution lists that that “Northwestern University students are a diverse population that identify with many of the groups that Donald Trump harmed during his campaign and presidency,” and also “the conservative political ideology of Donald Trump, including those that support him, do not align with the views of the average Northwestern undergraduate.” [emphasis mine]

In other words, these students will not tolerate on their campus anyone who expresses an opinion they disagree with. There will be no free speech, no open discourse, and no debate. Agree with them, or you will be silenced, blackballed, and removed.

NOAA struggles with concept of letting private commercial space build its satellites

9:49 am

Capitalism in space? An article today in Space News, “NOAA to take first step toward a small satellite constellation”, describes at great length NOAA’s recent effort to rethink how it builds its weather satellites, shifting from large and expensive single satellites launched years apart to constellations of smallsats that provide more redundancy and are cheaper and easier to replace.

What the article misses, as does NOAA apparently, is that this shift should not be designed by NOAA at all. During the Trump administration there was pressure on this agency to do what NASA had, stop designing and building its satellites but instead become a customer that hires private satellite companies to do it instead.

Not much came of that pressure. NOAA hired one private company to study the idea of building a private satellite to observe the Sun. It also awarded three companies experimental contracts to provide NOAA weather data from already orbiting smallsats.

That was it. NOAA made no other attempts to encourage private companies to design and build weather satellites for it, even as it struggled to get its own satellites off the ground. The second new GOES satellite in a constellation of four for providing global weather coverage failed almost immediately after launch in 2018. Overall, that constellation is expected to cost $11 billion, $4 billion more than initially budgeted. And it is years behind schedule.

What the article above suggests is that, with the Trump administration gone, NOAA has now abandoned the effort to transition to privately-built weather satellites. Instead the article describes at great length the effort by NOAA to redesign its satellites from big, rare, and costly to small, frequent, and cheap.

This effort will fail. Government agencies like NOAA are incapable of accomplishing such a task. They do not think in terms of profit, and keeping costs down to maximize those profits. Instead, such government institutions see high costs as beneficial, as they pump more money into their operations.

Until elected officials force NOAA to change, it will not, and its weather satellites will continue to be late, expensive, and untrustworthy. Sadly, the elected officials we have today, especially in the Biden administration, are not going to do that. They are as satisfied with the present situation as NOAA is.

SpaceX drone ship arrives in California

9:14 am

Capitalism in space: One of SpaceX’s two drone ships used by its Falcon 9 first stages for ocean landings has arrived in California in preparation for frequent Starlink launches from Vandenberg Space Force Base.

The journey began on the East Coast two weeks ago and included passage through the Panama Canal. Once the drone ship gets offloaded, it will be based at Pier T, where it be part of recovery operations for the Starlink landings that potentially could occur in late July or early August.

These California launches will allow SpaceX to increase the global coverage of its Starlink constellation. It will also allow the company to begin frequent launches from both coasts.

China launches communications satellite for space effort

8:15 pm

Using a Long March 3C rocket China today successfully launched a communications satellite for use by its manned space missions and its space station, similar to the TDRS satellites used by NASA for similar purposes.

This satellite is the fifth such satellite launched, and is likely intended to enhance communications between the ground and China’s new space station.

No word on where the first stage crashed, or whether it landed near habitable areas.

The leaders in the 2021 launch race:

21 China
20 SpaceX
11 Russia
3 Northrop Grumman

The U.S. still leads China 29 to 21 in the national rankings.

Today’s blacklisted American: What the last six months has revealed

12:42 pm

Today's modern witch hunt
Reporting daily the modern witch hunt against freedom and
independent thought.

It is just about six months since I decided to do a daily column entitled “Today’s Blacklisted American.” In that time I have documented more than 120 examples where one group of Americans thought it okay and proper to destroy the livelihood and freedom of other Americans, all because the latter said something the former did not like.

The link will take you to the full list of columns since mid-January. After six months I think it is time to assess what these columns have revealed. And that revelation is quite ugly.

Sublimating scallops on Mars

2:05 pm

Giant scallop on Mars
Click for full image.

Today’s cool image, shown in a rotated, cropped, and reduced version to the right, gives us a close-up look at one of the giant scallops found in the high mid-latitudes of the northern lowland plains of Mars, specifically in Utopia Basin north of the landing sites of both Perseverance and Zhurong. In fact, this particular image is only a few miles north of one of my previous cool images, Giant scallops on Mars, posted in December 2019.

The image was taken on February 3, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). While such scallops are not unusual in the mid-latitudes, their formation process is not well understood. As I noted in the 2019 post, ” scientists believe [pdf] the formation process is related to the sublimation of underground ice.”

According to [one hypothesis] scallop formation should be ongoing at the present time. Sublimation of interstitial ice could induce a collapse of material, initially as a small pit, then growing [away from the equator] because of greater solar heating on [that] side. Nearby scallops would coalesce together as can be seen to have occurred.

This hypothesis is not proven, and today’s cool image raises questions about it. Though the bright material at its center suggests exposed ice, supporting the idea that sublimation of ice near the surface created the scallop, the scallop scarps seem more extended and distinct to the south, not the north as this hypothesis proposes. Sunlight should hit the northern scarps more, which suggests they should retreat more instead of the southern scarp.

The overview map below provides the context.

Today’s blacklisted American: Baseball bans man for expressing his opinion at baseball games with banner

11:56 am

The Bill of Rights cancelled by Major League Baseball
Doesn’t exist at the professional baseball games.

This seems especially appropriate during the July 4th weekend: Major League Baseball (MLB) — joining Disney, Sea World, and Sesame Street — has officially banned Dion Cini from all baseball stadiums, simply because he routinely came to games and displayed a “Trump Won Save America” banner.

Cini’s Twitter profile describes him as “Guerilla Marketeer, Political Consultant, Founder of OperationFlagDrop & ‘Professional Provocateur.’”

He has skated with his flag on Wollman Ice Rink, where he was physically assaulted, even though the Trump organization operated Wollman Rink. Cini also unfurled what is rumored to be the world’s largest Trump flag on the front of Trump Tower in Manhattan in March of this year. Cini even dropped a “Trump Pride” flag one day after the end of Pride Month.

Cini has now been banned by MLB stadiums and Disney parks, Sea World, and Sesame Street. As per his Twitter account, he has no plans of stopping the flag drops.

First images from Ingenuity’s 9th flight today

10:20 am

Ingenuity landing, July 5, 2021

Ingenuity has apparently completed its 9th flight on Mars, its most challenging yet attempted. Based on the six images so far released from that flight, all taking during its landing, it appears the flight was successful. Or at least, the helicopter landed without incident or damage.

The photo to the right was the last picture taken just before touch down. From the caption:

NASA’s Ingenuity Mars Helicopter acquired this image using its navigation camera. This camera is mounted in the helicopter’s fuselage and pointed directly downward to track the ground during flight.

The dark shadow of the helicopter is clearly visible. If you want to see the entire sequence of six images, go to the Ingenuity raw image website and pick the “latest images” filter in the right column. At present it shows this sequence, though I am certain as the day passes images from the entire flight will start appearing.

As noted at the first link above, the flight was to be more than twice as long as any previous flight while flying over the roughest terrain. There was the real risk that its software would become confused by that terrain.

Sun unleashes strongest solar flare since last solar maximum

9:54 am

X1 solar flare as seen by Solar Dynamics Observatory

On July 3, 2021 the Sun emitted the first X-class solar flare of the rising present solar maximum, the first such flare since September 2017 during the previous maximum.

This flare is classified as an X1.5-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.

The image to the right was taken by the orbiting Solar Dynamics Observatory (SDO), designed to monitor the Sun continuously and catch such events.

More information here. The flare caused some disturbances to various radio instruments, though nothing that resulted in any serious consequences.

What the flare did demonstrate is that the Sun is definitely ramping up to solar maximum. In fact, the Sun has not been blank, with no sunspots on its facing hemisphere, since May 6th, the longest such stretch since the last solar maximum.

Sunspot update: The hot streak continues

8:01 am

This past weekend NOAA released its monthly update of its graph showing the Sun’s sunspot activity, with the new update covering the period through the end of June 2021. As I have done since I began this website eleven years ago, I post that monthly graph below, annotated to show the previous solar cycle predictions and thus provide context.

In June the hot streak of sunspot activity exceeding the prediction of NOAA’s solar science panel continued, with activity rising again after a tiny dip in May. Except for two months, since 2019 the number of sunspots each month has consistently exceeded the prediction. Furthermore, the ramp up of activity has been faster than expected.

Ingenuity's 9th flight plan
Click for full image.

The engineers running the Mars helicopter Ingenuity revealed today that they will be attempting their most ambitious flight for the helicopter’s ninth flight, presently scheduled for no earlier than July 4th.

I have annotated the map to the right to show Ingenuity’s present position and its approximate landing area.

Without question this flight will be the riskiest taken by Ingenuity so far, more than doubling the flight distance achieved on any previous flight. More important, it will be flying over terrain far rougher than it was initially designed for.

More parachute problems for Europe’s Franklin Mars rover

10:11 am

During a parachute drop test in late June, following a redesign of the parachute with U.S. help, engineers for the ExoMars Rosalind Franklin Mars rover found the chute still experienced problems that tore it during deployment.

They actually performed two drop tests, a day apart, using two different parachutes, with the first test apparently going off without a hitch. However, according to the press release:

“The performance of the second main parachute was not perfect but much improved thanks to the adjustments made to the bag and canopy. After a smooth extraction from the bag, we experienced an unexpected detachment of the pilot chute during final inflation. This likely means that the main parachute canopy suffered extra pressure in certain parts. This created a tear that was contained by a Kevlar reinforcement ring. Despite that, it fulfilled its expected deceleration and the descent module was recovered in good state.”

I have embedded below the fold the only video released by the European Space Agency. It is not clear whether this is from the first or second test. Near the end it appears that the pilot chute above the main chute might be separated, but the video ends before that can be confirmed.

Though ESA has apparently improved the chute’s performance significantly since its earlier failures that contributed to the delay of ExoMars from last year to 2022, they still haven’t gotten the chute completely right. Fortunately they still have time to get it fixed before that ’22 launch.

1776 – Hatching an Egg

6:01 pm

A evening pause: On this day, July 2nd, the day the Founding Fathers actually signed the Declaration of Independence, I think it appropriate to once again watch this wonderful song from the 1976 movie version of the 1972 musical, 1776. As I said in earlier posts of this song on Independence Day, “not only did the musical capture the essence of the men who made independency happen, it is also a rollicking and entertaining work of art.”

And despite the hate being spewed against America and its founding principle that all humans are created free with the right to life, liberty, and the pursuit of happiness, that truth still shines. As John Kennedy said of himself, ourselves, and these founding fathers. “We stand for freedom.”

Progress docks with ISS

12:36 pm

As expected a Russian Progress freighter docked with ISS yesterday, on schedule and with no mishaps.

I report this non-news story simply because of the Russian claim yesterday that a SpaceX Starlink satellite and Falcon 9 upper stage threatened a collision with that freighter as it maneuvered in orbit prior to docking.

Not surprisingly, there was no collision. The Russians knew this, or they would never have launched as they did. They made a stink about it as a ploy to stain SpaceX, a company that has taken almost all their commercial launch business by offering cheaper and more reliable rockets.

Today’s blacklisted American: YouTube blacklists group exposing Chinese genocide in its Xinjiang region

12:12 pm

The Bill of Rights cancelled on YouTube
No free speech allowed on YouTube.

Today’s blacklisting victim is not really an American, but since it is an American company doing the blacklisting I think the story is applicable. It appears Google-owned YouTube has decided to remove videos on the Atajurt Kazakh Human Rights’ channel that expose the genocide and ethnic cleansing that China is doing to as many as a million people in its Xinjiang region.

Atajurt Kazakh Human Rights’ channel has published nearly 11,000 videos on YouTube totaling over 120 million views since 2017, thousands of which feature people speaking to camera about relatives they say have disappeared without a trace in China’s Xinjiang region, where UN experts and rights groups estimate over a million people have been detained in recent years.

On June 15, the channel was blocked for violating YouTube’s guidelines, according to a screenshot seen by Reuters, after twelve of its videos had been reported for breaching its ‘cyberbullying and harassment’ policy.

The channel’s administrators had appealed the blocking of all twelve videos between April and June, with some reinstated – but YouTube did not provide an explanation as to why others were kept out of public view, the administrators told Reuters.

Following inquiries from Reuters as to why the channel was removed, YouTube restored it, explaining that it had received multiple so-called ‘strikes’ for videos which contained people holding up ID cards to prove they were related to the missing, violating a YouTube policy which prohibits personally identifiable information from appearing in its content. They reinstated the channel on June 18 but asked Atajurt to blur the IDs.

Perseverance’s most recent view of Jezero Crater

10:30 am

Panorama by Perseverance, Sol 130, July 2, 2021
Click for full resolution.

Overview map
Click for interactive map.

Cool image time! The panorama above, reduced to post here, is made from two navigation camera images on the Mars rover Perseverance, found here and here.

The map to the right, taken from the “Where is Perseverance?” website and annotated further by me, shows with the yellow lines what I think (but am not sure) is the area seen in the panorama.

The navigation cameras on Perseverance are more wide angle than the navigation cameras on Curiosity, in order to cover a larger area. They thus produce a slight fisheye distortion, illustrated by the curve of the horizon.

The large mountain in the center right is likely the crater rim. You can also see the knobs to the left as indicated on the overview map. The rover is now about halfway to the southernmost planned spot it is expected to reach within the floor of Jezero Crater, which is about a half to three quarters of a mile further south.

The terrain seems quite desolate and barren, which of course is no surprise, because that is what it is like on all of the surface of Mars. No plant life, just rocks and dirt. While Curiosity is now in the mountains, Perseverance remains on the crater floor, so the points of interest (from the mere tourist’s perspective) are small or far away.

More delays in India’s space program

9:36 am

Blaming COVID-19, the head of India’s space agency ISRO, K. Sivan, announced yesterday that they are delaying the first unmanned test flight of their manned space capsule so that it will not fly in 2021 as planned.

ISRO had planned eight launches in 2021, but has so far only flown one, and that launch took place in February. Since then no launches have occurred. Moreover, in 2020 India only completed two launches, far less than planned. In other words, their fear of COVID has essentially shut down their entire government space program for two years.

Meanwhile, China, Russia, SpaceX, and most other private companies roll on, launching frequently and without any negative consequences. The difference tells us that India is over-reacting, and allowing its fearful bureaucracy to run the show. The result is that they are losing ground not only in their effort to fly their first manned mission, but in commercial market share. I am certain that satellite companies that would have flown on their rockets have been shifting their business to SpaceX, Rocket Lab, and many of the other new rocket startups in the U.S.
