It’s drill time for Perseverance!

The Perservance science team is preparing the rover for its first drill hole and the first collection of a sample to cache so that a future spacecraft can return it to Earth.

They are presently at the general location where they wish to drill, and are looking for the exact right spot.

The sampling sequence begins with the rover placing everything necessary for sampling within reach of its 7-foot (2-meter) long robotic arm. It will then perform an imagery survey, so NASA’s science team can determine the exact location for taking the first sample, and a separate target site in the same area for “proximity science.”

“The idea is to get valuable data on the rock we are about to sample by finding its geologic twin and performing detailed in-situ analysis,” said science campaign co-lead Vivian Sun, from NASA’s Jet Propulsion Laboratory in Southern California. “On the geologic double, first we use an abrading bit to scrape off the top layers of rock and dust to expose fresh, unweathered surfaces, blow it clean with our Gas Dust Removal Tool, and then get up close and personal with our turret-mounted proximity science instruments SHERLOC, PIXL, and WATSON.”

“After our pre-coring science is complete, we will limit rover tasks for a sol, or a Martian day,” said Sun. “This will allow the rover to fully charge its battery for the events of the following day.”

Sampling day kicks off with the sample-handling arm within the Adaptive Caching Assembly retrieving a sample tube, heating it, and then inserting it into a coring bit. A device called the bit carousel transports the tube and bit to a rotary-percussive drill on Perseverance’s robotic arm, which will then drill the untouched geologic “twin” of the rock studied the previous sol, filling the tube with a core sample roughly the size of a piece of chalk.

Perseverance’s arm will then move the bit-and-tube combination back into bit carousel, which will transfer it back into the Adaptive Caching Assembly, where the sample will be measured for volume, photographed, hermetically sealed, and stored. The next time the sample tube contents are seen, they will be in a clean room facility on Earth, for analysis using scientific instruments much too large to send to Mars.

Not all drill samples will be cached in this manner.

With this press release and press conference NASA continued to push the fiction to the press that Perservance’s prime mission is to search for life. That is a lie designed to catch the interest of ignorant journalists who don’t know anything. The rover’s real mission is to study the overall Martian geology in Jezero Crater in order to better under the planet’s present geology as well as the geological history that made it look like it does today.

If the scientists using Perseverance find evidence of life, wonderful, but that is not their prime goal.

July 21, 2021 Zimmerman podcast interview on Pratt on Texas

Today Robert Pratt made available an hourlong podcast interview I did with him earlier this week, devoted entirely to discussing my new book, Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space.

The podcast is available here.

This was my first long interview discussing this book. It is also the first where you can hear the detailed impressions of it from someone else. Robert Pratt is a very educated radio host, with deep knowledge of western history and culture. That he repeatedly noted how Conscous Choice surprised him by teaching him things he hadn’t known and hadn’t even thought of I found very gratifying. I’ll let his closing words in the interview sum up his opinion of my book:

I really do believe that everybody needs to get a copy of Conscious Choice. It is that important a book. It is one of the most important books given today’s social upheaval.

There are lot of good histories out there, but they are mostly just retreads of the primary documents that we’ve read before. I get bored with them.

This book is new. This book is primary source history that will enlighten you and give you knowledge.

If you listen you will find out that I am not spinning his words. Nor is he merely providing a plug for a guest. This is his honest appraisal of Conscious Choice, after reading it.

New studies show that the biggest risk to kids from COVID are the policies of governments

New studies about COVID-19 and its effect on children continue to show that the strigent health policies being demanded by government agencies like the CDC and WHO and many Democrats are actually the biggest health threat for children than the virus itself.

First, a major survey of 48,000 children who had become infected with COVID-19 has found that absolutely no healthy children died from the disease.

Dr. Marty Makary is a medical expert and professor at the Johns Hopkins School of Medicine, Bloomberg School of Public Health, and Carey Business School. His research team “worked with the nonprofit FAIR Health to analyze approximately 48,000 children under 18 diagnosed with Covid in health-insurance data from April to August 2020.”

After studying comprehensive data on thousands of children, the team “found a mortality rate of zero among children without a pre-existing medical condition such as leukemia.”

Let me repeat that. They looked at tens of thousands of kids under the age of 18 and could not find one case where a healthy child died. All recovered. None needed a vaccine, as their young and very strong immune systems did what those immune systems have always done, fought off a sickness to give them an immunity for the rest of their lives.

So kids are safe from COVID, even if they are not vaccined and actually catch the virus and get sick.

At the same time, other studies have found that both masks and the vaccines are actually a greater health threat to children than the virus itself.

Another “What the heck?” photo from Mars

Isolated clump of mounds on Mars
Click for full image.

The cool image to the right, cropped and reduced to post here, was taken a decade ago, on August 25, 2011, by the context camera on Mars Reconnaissance Orbiter (MRO), It shows a flat plain with a sudden clump of mounds or hills at the center.

This is one of those pictures from Mars which I like to call a “What the heck?” image. What caused the mounds, and why are they found only in this concentrated clump, with the rest of the terrain around them generally flat?

Though the context image was taken a decade ago, no follow-up high resolution images were taken of this area until very recently.

Below is the one recent high resolution image taken by MRO on May 12, 2021, cropped and reduced to show the bottom half of the mound clump as shown by the white box. It makes the mystery even more puzzling.

Today’s blacklisted American: Army chaplin, threatened with punishment for criticizing Biden administration, sues and wins Pyrrhic victory

The Bill of Rights cancelled for conservatives
No first amendment allowed for conservatives.

Today’s blacklist story illustrates a growing trend I am finding in these stories of the modern leftist effort to silence and blackball anyone who criticizes or opposes it. Increasingly, the victims of this intolerance are fighting back, both in public and in the courts. How successful that resistance has been however remains unclear.

In today’s story, a decorated Army chaplin had posted in January on Facebook strong criticism of the incoming Biden administration’s decision to allow men who claim they are women (and vice versa) to serve in the military, and was immediately sanctioned by his superiors for doing so.

[U.S. Army Chaplain (Major) Andrew Calvert] objected to the anticipated government policy change. “How is rejecting reality (biology) not evidence that a person is mentally unfit (ill), and thus making that person unqualified to serve. There is little difference in this than over those who believe and argue for a ‘flat earth,’ despite the overwhelming evidence to the contrary,” Calvert wrote in his comment, according to Army Times.

“The motivation is different, but the argument is the same. This person is a MedBoard for Mental Wellness waiting to happen. What a waste of military resources and funding!” he concluded.

Following an investigation, Calvert was issued a General Officer Memorandum of Reprimand (GOMOR) on April 22 by Lieutenant General Robert P. White.

In May Calvert obtained legal support and sued. Less than a month later, the Army backed down, ending its persecution of Calvert, clearing his record.

That Calvert fought the effort by the military to reprimand him for his opinions is commendable. Nonetheless, in this case the victory appears somewhat hollow.

NASA funds hopper to jump into shadowed lunar craters and find ice

Capitalism in space: NASA has awarded a $41.6 million contract to Arizona State University and the private company Intuitive Machines to build a tiny hopper that will be used to explore the permanently shadowed craters near the Moon’s south pole, looking for water ice.

Micro-Nova can carry a 1-kilogram payload more than 2.5 kilometers to access lunar craters and enable high-resolution surveying of the lunar surface under the flight path. Intuitive Machines’ Micro-Nova, a lunar hopper that will explore permanently shaded regions of the moon.

…“Intuitive Machines’ Micro-Nova is our first-ever chance to explore from within a lunar permanently shaded region (PSR),” said the mission science lead Mark Robinson, of ASU’s School of Earth and Space Exploration. “We will be able to take very high resolution color images near the hopper and black and white images of about half the PSR. What will we see, that is the question!”

This tiny hopper, only 30 inches square, will be built by ASU and launched on Intuitive Machines’ first Moon lander, Nova-C, presently scheduled for launch in December 2022.

Democrat proposes new tax on private manned spaceflight

That didn’t take long! Mere hours after New Shepard completed its first suborbital manned commercial flight, a Democrat in the House of Representatives introduced a bill in Congress to impose a tax on private manned spaceflight.

Oregon Democrat Rep. Earl Blumenauer, who is a member of the House Ways and Means Committee, on Tuesday introduced what he is calling the Securing Protections Against Carbon Emissions (SPACE) Tax Act, which would create excise taxes on commercial space flights carrying human passengers for purposes other than scientific research.

“Space travel isn’t a tax free holiday for the wealthy,” Blumenauer wrote on Twitter. “We pay taxes on plane tickets. Billionaires flying into space—producing no scientific value—should do the same, and then some.”

The measure would include a per-passenger tax on the price of a commercial flight to space and a two-tiered excise tax for each launch into space. The first tier would apply to flights between 50 miles and 80 miles above Earth’s surface, while the second “significantly higher” rate would apply to flights more than 80 miles above Earth’s surface.

This typical Democratic Party response to the acheivement of others reminds me of a pertinent quote from Ronald Reagan:

Government’s view of the economy could be summed up in a few short phrases: If it moves, tax it. If it keeps moving, regulate it. And if it stops moving, subsidize it.

While Reagan was describing many of the actions of politicans from both parties, the Democratic Party is today particularly abusive. Private enterprise has in the past decade done things in space the government and NASA spent years trying to accomplish, with zero success, while wasting billions of taxpayer dollars. The Democrats resent that success, and are very eager to squelch it. Rather than have any American achievement in space, created by the citizens of the nation and independent of their interference, they would rather destroy it. Even as they extort as much money as they can from it.

Russia launches Nauka, its first new ISS module in 11 years

Russia today used its Proton rocket to successfully place in orbit its new ISS module, Nauka, the first new Russian module in eleven years, and fourteen years after it was originally supposed to launch.

After launch and orbit insertion, the module, MLM-U Nauka, is now performing an eight day phase to the Station for an automated docking on July 29 to the nadir docking port of the Zvezda service module, a port currently occupied by the Pirs module.

Upon arrival, Nauka will become the third largest module of the Russian segment of the ISS and will add 70 cubic meters of space to the Station’s internal volume, a third Russian-side sleeping location, an additional toilet, as well as new water regeneration and oxygen production systems — augmenting some of the original systems in Zvezda that are showing their 22 year age.

The main task for the Nauka module will be to conduct scientific experiments. The pressurized compartment of the module contains 21 universal working places (URM), including four locations with sliding shelves, a glove box, a frame with an automatic rotating vibration-proof platform, and a porthole with a diameter of 426 mm for visual and instrumental observations.

The article above provides a very interesting review of Nauka’s complex and difficult history.

The leaders in the 2021 launch race:

23 China
20 SpaceX
12 Russia
3 Northrop Grumman

The U.S. still leads China 29 to 23 in the national rankings.

Israel: Airborne High Power Laser Weapon test

An evening pause: I’m not sure if this fits as an evening pause, but the engineering is startling, and has ramifications both good and bad, for the future. The first half of the video shows the test, the second half explains it.

Israelis are surrounded by neighbors dominated by a culture that wishes to kill them all. They need this kind of defense, especially because the world will no longer defend them against this threat of genocide. In fact, many of our ruling “intellectual” class celebrate that possibility.

That they are forced to develop this technology sadly means that some bad actors will get it soon as well. The dark age is so fast approaching that it takes the breath away. That this is where we are, on the anniversary of the Apollo 11 landing on the Moon, is tragic beyond words.

Ice-filled craters in Mars’ glacier country?

Craters in Protonilus Mensae
Click for full image.

Today’s cool image returns us to the chaos region dubbed Protonilus Mensae, the middle of three adjacent mensae regions in the northern hemisphere that I like to dub Mars’ glacier country because there is so much evidence of buried ice there.

The photo to the right, cropped to post here, was taken on May 31, 2021 by the high resolution camera of Mars Reconnaissance Orbiter (MRO). Titled “Layered Feature in Crater in Protonilus Mensae,” the section I have posted focuses on several craters, with the one with the central mesa likely the picture’s target. Based on many similar features found in craters in this region, it is somewhat safe to assume that this mesa is made of buried ice.

The overview map below as always provides the context.

Today’s blacklisted American: Catholic hospitals threatened with cancellation by University of California

Religious beliefs banned by University of California
Religious beliefs: Banned by University of California.

The modern dark age: The Board of Regents of the University of California (UC) on June 23, 2021 voted to end its affiliation with all Catholic hospitals if they do not agree to perform “abortions, euthanasia, assisted suicide and the direct sterilization of patients,” in direct violation of their Christian religious beliefs.

The policy states that UC physicians practicing at a sectarian hospital must be permitted to provide any treatment at that location to a patient who can’t be safely transferred to another facility — even if the treatment would violate religious restrictions. Affiliated hospitals will have until Dec. 31, 2023, to comply with the policy, or the affiliation agreement must be canceled.

“We know that transfers are not always in the patient’s interest”, board Chair John A. Pérez, who crafted the key language approved by the board, said after the board’s meeting, conducted remotely Wednesday afternoon. [emphasis mine]

Do you see the lie in the highlighted words? All of these treatments are optional, and can be scheduled. I can see almost no medical issue preventing the safe transfer of a patient from of a Catholic hospital in order to get one of these procedures. In fact, I can’t even see a reason for any patient who wants an “abortion, euthanasia, assisted suicide, or direct sterilization” to even be in a Catholic hospital.

The only reason the university’s Board of Regents has for imposing such a rule is to either force Catholics to violate their religious beliefs, or to get such religious hospitals blackballed from serving any patients,. and thus in the long run destroy them as institutions.

As noted by the Alliance of Catholic Healthcare,

Rocket Lab identifies cause of May launch failure; ready to launch again

Capitalism in space: Rocket Lab announced yesterday that it has identified and corrected the cause of a May 15 launch failure and is now ready to resume launches, as early as before the end of July.

Rocket Lab said an investigation by the company traced the root cause to the rocket’s second stage engine igniter system. A problem with the igniter corrupted signals in the computer on the stage, which in turn caused the thrust vector control system to “deviate outside nominal parameters.” The engine computer then shut down the Rutherford engine.

The igniter problem, the company said, resulted from “a previously undetectable failure mode within the ignition system that occurs under a unique set of environmental pressures and conditions” not noticed in previous testing of the engine or on previous Electron launches. Engineers have replicated the problem in the lab and created what Rocket Lab called “redundancies” in the ignition system, including changes to the design of the igniter and how it is manufactured, to prevent the problem from happening again.

Rocket Lab has had two launch failures in the past year, so getting back flying as quickly as possible is critical for them, especially because a lot of new smallsat launch companies are coming up from behind. Virgin Orbit initiated commercial launches this year, having already completed two, and Astra and Firefly both seem ready, based on recent announcements, to make their first orbital launches before the end of this year.

SpaceX completes first static fire test of Superheavy prototype #3

Superheavy booster #3 fires
Superheavy booster #3 fires.

Capitalism in space: SpaceX yesterday successfully completed the first static fire test of the third Superheavy prototype, firing up three Raptor engines for about two seconds.

I have embedded the live stream from NASASpaceflight.com below the fold, cued to just before the engines fire. Because there was a delay of a few minutes from when the static fire was expected and when it actually happened, the announcers had began talking and were caught off guard by the burn.

Next up:

Booster 3 provides a first-time operation for fueling the huge booster with Liquid Oxygen (LOX) and Liquid Methane (CH4) during the test. How much propellant will be loaded, and the schedule for the sequence was unknown. However, NSF’s Adrian Beil wrote a feature on the expectations based on previous experiences with Starship being applied to Super Heavy.

Based on those evaluations, it was expected that Super Heavy would also undergo a Starship-like countdown of 45-60 minutes, with fueling beginning in the 30-40 minute range. Engine chill would then follow at T-12 minutes, ahead of the firing. As with previous Static Fires, the T-10 minute siren sounded, as per the alert notice to local residents. However, as with Starship, mini-holds can be expected, pushing the ignition time to the right. This proved to be the case on Monday.

The booster fired up all three engines for the expected duration, confirmed by Musk before he noted that “depending on progress with Booster 4, we might try a 9 engine firing on Booster 3.”

Booster #4 will be put on the orbital launchpad rather than the test pad, and is likely the booster to be used for the first orbital test flight of Starship, likely to be launched before the end of summer.

Blue Origin completes first commercial suborbital flight

New Shepard just prior to landing
New Shepard just prior to landing.

Capitalism in space: Blue Origin this morning successfully flew its first commercial suborbital flight using its New Shepard spacecraft, taking Jeff Bezos and four other passengers, one paying, to an altitude of 66.5 miles.

The flight lasted just over ten minutes.

I have embedded the video of the flight, cued to just before launch, below the fold. Try to ignore the blather of Blue Origin’s announcer, which fortunately mostly stops once the spacecraft passes 62 miles and enters space. At that point microphones from inside the capsule take over, and you get to hear the reaction of the passengers themselves.

A grand success for Blue Origin and Jeff Bezos. And another grand success for freedom and private enterprise.

Next up, the beginning of regular commercial orbital manned tourist flights, starting in September. Here is the present flight manifest:

  • September 2021: SpaceX’s Dragon capsule flies four private citizens on a three day orbital flight
  • October 2021: The Russians will fly two passengers to ISS to shoot a movie
  • December 2021: The Russians will fly billionaire Yusaku Maezawa and his assistant to ISS for 12 days
  • cDecember 2021: Space Adventures, using a Dragon capsule, will fly four in orbit for five days
  • January 2022: Axiom, using a Dragon capsule, will fly four tourists to ISS
  • 2022-2024: Three more Axiom tourist flights on Dragon to ISS
  • 2024: Axiom begins launching its own modules to ISS, starting construction of its own private space station
  • c2024: SpaceX’s Starship takes Yusaku Maezawa and several others on a journey around the Moon.

Watching New Shepard’s first manned commercial flight tomorrow

Blue Origin will be live streaming the suborbital flight tomorrow of its New Shepard spacecraft, carrying Jeff and Mark Bezos, Wally Funk, and passenger 18-year-old Oliver Daemen, his ticket paid for by his father at an undisclosed price.

The broadcast begins at 7 am (Eastern), with launch scheduled for 9 am (Eastern).

The flight itself will be about about ten to twelve minutes total, expecting to reach an altitude exceeding 67 miles, Though it will fly higher than Virgin Galactic’s suborbital flight last week, which reached about 53.5 miles, it will be far shorter. Because Virgin Galactic’s spacecraft takes off attached to the bottom of an airplane, the flight includes more than an hour of flight time getting up to the right altitude to release the spacecraft.

New Shepard launches from the ground, goes straight up, and reaches its maximum height within minutes.

Which is a better deal? That’s up to you. Since orbital tourist flights are now available and will be launching monthly beginning in September, both of these very short suborbital hops seem much less interesting then they would have only two years ago.

Musk donates more big money to revitalizing downtown Brownsville

It appears that a charitable foundation established by Elon Musk has recently decided to up its donations to the Brownsville Community Improvements Corporation by an extra $1 million, the money aimed at helping to revitalized the downtown of Brownsville, the nearest large city to SpaceX’s Boca Chica spaceport.

The donation was revealed during remarks by Josh Mejia, executive director of the Brownsville Community Improvements Corporation, during a Brownsville developers luncheon .

In his remarks, Mejia, pictured above, gave an update on the e-Bridge Center and other quality of life improvements coming to Brownsville. But, he received the biggest applause when he mentioned inward investment by Elon Musk. “I was texting back and forth with my board members and about 45 minutes ago I receive an email from the Musk Foundation. It is like perfect timing. It is like they know we are here. Well, they just mentioned they donated another million (dollars) towards this program. So, now we have $2 million,” Mejia said. The audience cheered.

This donation is all part of the modern game that requires big business enterprises to make payoffs to local and national politicians and “community activists.” Both Elon Musk and Jeff Bezos know this, and are playing the game to hilt. Both know that the politicians and “community activists” have been telling them, “Nice business you got here, shame if something happened to it.” Bezos responded by donating big to DC’s Air & Space museum, while spreading the wealth to many space advocacy groups.

Musk is instead focusing his payoffs to the local community, where it might do the most good for both him and the locals that his business affects. This donation is not the first he has made to Boca Chica, Brownsville, and south Texas. His foundation has also donated $20 million to the county schools, and another $8 million for other downtown Brownsville projects. The results, obviously helped by the business SpaceX is also bringing to the town, have been noticeable.

In the months since Musk pledged his $10 million, at least 10 downtown properties have gone under contract with interested buyers, said real estate broker Bob Torres Jr. Buildings that used to lease for 25 cents a square foot are now leasing for $1 to $1.50 per square foot.

Home prices have increased nationwide due to the pandemic and low inventory. In Brownsville, this trend has been exacerbated by SpaceX. “People are buying houses sight unseen from Washington state, Portland, Oregon,” Torres said. “They’re going above the asking price, which hardly ever happens.” Real estate broker Bruno Zavaleta III had a client drive from Atlanta and buy three houses.

According to the Brownsville/South Padre Island Board of Realtors, the median price for a home in Brownsville was $212,900 in June, up 47 percent from June 2020. To help with inventory, Esperanza Homes is building 675 houses in northern Brownsville. It will develop this master-planned community over the next six to eight years with a nonprofit community housing development organization called “come dream. come build.”

This pumping of donations by Musk to the local community however will not sell well with the mafia in Washington. The money isn’t going to them, and bullies don’t like that, even if the money is really doing good. Bezos understands this. It doesn’t really matter if the money he donates accomplishes anything real. What matters is that he has paid off the thugs who could make big trouble for him in the future.

Right now it is unclear who’s strategy will work best for protecting each company’s interests. Much will hinge on what each company actually accomplishes in the next few years. SpaceX is clearly ahead in this area, but Blue Origin can certainly catch up.

Today’s blacklisted American: 19th century poet Walt Whitman

Walt Whitman, banned
Great poets like Walt Whitman
now banned at Rutgers

The onset of the modern dark age: Ivy league college Rutgers University in Camden New Jersey is now removing its monument to 19th poet Walt Whitman because of petitions and slanders against him by today’s blacklist culture.

Rutgers University-Camden will remove a statue of the famous poet Walt Whitman from the center of campus as a result of activists’ petitions and a recommendation from a committee of scholars. The statue of Whitman, featured prominently in the front courtyard of Camden’s Campus Center, will be “relocated to a historically relevant site on campus and contextualized,” interim Chancellor Margaret Marsh recently announced in an email to students and employees.

That new location has yet to be announced by campus officials.

A petition circulated last year stated that “the statue of Walt Whitman glorifies a man who we should not hold such a place of honor on our campus. … He instead stood for white supremacy and racism against Black and Indigenous Americans.”

In other words, because Whitman was a man of his time and not perfect, his memory must be wiped from all history, his poems burned, and all effort to teach his poetry ended forthwith.

This effort is quite symptomatic of the entire modern leftist effort to slander all of American history.

Cracks, chaos, and maybe caves in one place on Mars

Mosaic of Avernus Cavi fissures
Click for higher resolution. Original images found here and here.

Today’s cool image to the right is a mosaic I have made from two images taken by the context camera on Mars Reconnaissance Orbiter (MRO), showing a most intriguing region on Mars dubbed Avernus Cavi, located in the large volcanic plain called Elysium Planitia between the giant volcanoes Elysium Mons and Olympus Mons, a region I like to call Mars’ volcano country.

The mosaic shows in one picture much of the typical terrain in Avernus Cavi. We see many linear depressions or cracks, created when the ground stretched and cracked at weak points. We also see many depressions that suggest sinkholes, places where the surface sagged down because of a void below ground.

The area of knobs and mesas in the picture’s southeast quadrant is very typical Martian chaos terrain, the later result of long term erosion of these cracks and depressions.

The white box shows the area covered by the image below.

The future of SLS?

In this long NASASpaceflight.com article describing the building the second core stage for NASA’s SLS rocket (the stage scheduled to take astronauts around the Moon in September 2023) was also additional information about the status of later core stages, still not entirely funded.

The key tidbit of information is this:

Core Stage-3 is the first build under the new “Stages Production and Evolution Contract” that was initiated in 2019; the contract is not yet completely finalized, with the latest estimate for definitization being early in Fiscal Year 2022 (which begins on October 1st, 2021).

Both NASA and Boeing are proceeding under the assumption that this Congress will approve full funding for later SLS rockets after flights one and two. While the signs strongly suggest that funding for at least two more rockets will arrive, that funding still depends largely on the success of the first unmanned SLS test flight, tentatively scheduled for November-December 2021.

It also depends on the political winds, and when Starship starts reaching orbit somewhat regularly (and cheaply). When that happens, all bets are off on the future of SLS. At some point it will become obvious that it can’t compete against that SpaceX rocket, and Congress will shift its funding appropriately.

Sadly, knowing Congress and the corrupt DC culture, this change will likely only happen after a lot of taxpayer money is wasted on a rocket that is simply too expensive and too cumbersome, and thus not practical for making space exploration possible.

China launches four satellites

Using its Long March 2C rocket, China today successfully launched four satellites, three military reconnaissance satellites and one data communications satellite.

While the first stage crashed inside China (no word on whether it landed near habitable areas), China also claimed it attempted a recovery of the fairings for reuse. At this time no information has been released on what was achieved.

The leaders in the 2021 launch race:

23 China

The lacy rocks of Mars

Lacy rocks on Mars
Click for full image.

Cool image time! The image to the right, cropped and reduced to post here, was taken on July 16, 2021 by the Mars rover Curiosity, using its high resolution mast camera.

There isn’t much to say. These are alien rocks, created in a place with a gravity only about a third that of Earth’s in a climate that is very different. Their delicate nature suggests we are looking at something that was once more substantial and has since been undergoing erosion.

Nor has it been that unusual to find rocks so dainty on Mars. In fact, the more Curiosity has climbed, the more such things have been visible. And similar things were seen by the rovers Spirit and Opportunity.

How such rocks formed initially in the far past, under what climate conditions, remains the number one mystery on Mars. What is now causing it to flake away into such a finespun gossamer of complexity is as much a mystery, tied more to the climate and geology of Mars today.

This rock sits on the bottom flank of Mt Sharp in Gale Crater, at the highest elevation Curiosity has yet climbed. At this point the rover has just entered a new geological unit, what scientists have dubbed the sulfate unit. The evidence gathered from a distance (that so far appears confirmed by recent observations) suggest that this unit was formed under a fluctuating environment that laid down many layers of sediment as conditions ebbed and flowed.

China test flies reusable suborbital spacecraft

The new colonial movement: China’s state-run press today announced that it had recently flown and landed a new reusable suborbital spacecraft. Here’s their full release:

A reusable suborbital carrier landed stably at an airport in Alxa League in north China’s Inner Mongolia Autonomous Region during a flight demonstration and verification project on Friday.

Earlier on Friday, the carrier was launched from the Jiuquan Satellite Launch Center in northwest China’s Gobi Desert. Its first flight mission was a complete success.

Developed by the China Aerospace Science and Technology Corporation, the reusable suborbital carrier can be used in the space transport system.

The success of the flight has laid a solid foundation for the development of China’s reusable space transportation. Enditem

The release provided no further information. It also provided no images.

This could very much be a real thing, but it also could be entirely fake. The timing of such a factual-devoid press release, coming as it does between two different American commercial suborbital flights, suggests the Chinese government does not want to appear left out, and is claiming, without producing any evidence, that it too has a reusable suborbital spacecraft.

If this release is fake, it also does not mean that China does not have such a spacecraft in development. In fact, it almost certainly does. Like the Soviet Union, China’s state-controlled press has a tendency to exaggerate their achievements for propaganda reasons. But like the Soviet Union, China is careful to base the exaggerations on actual achievements or plans, no matter how tentative.

Based on this, I suspect that what this release tells us is that China’s government is building such a thing, but might not have actually flown it yet. If they have as the press release claims, then expect some images in the next week or so.

Hubble returned to science operations

Engineers today completed their testing of their computer hardware fix on the Hubble Space Telescope and took it out of safe mode, allowing science observations to resume after more than a month.

The first observation is scheduled for Saturday afternoon after some instrument calibrations are completed. Most observations missed while science operations were suspended will be rescheduled for a later date.

Now let us all pray that there are no more major failures for the next few years until the U.S. capabilities in space grow and a relatively fast mission to repair the telescope is possible.

First attempts to map the layered geology of Mars

layers in Jiji Crater on Mars
Click for full image.

Today’s cool image illustrates well the central task of much of today’s geological research on Mars, using the orbital images to try to map out the visible geological layers seen, and figure out if those layers mark over wide regions specific geological epochs, as they do on Earth.

The photo to the right, cropped and reduced to post here, was taken on May 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and featured on July 12th as a captioned image entitled “Layers Blanket a Crater Floor.” From the caption:

This image shows a layered rock formation within Jiji Crater that has eroded into buttes and stair-like layers.

This formation extends west and east. Similar layered rocks are within several craters in Arabia Terra and Meridiani Planum, including [nearby] Sera and Banes craters. The similarities suggest that the same process was forming deposits over a large geographic area long ago. Our image also indicates that much of the formation has eroded away relative to what has remained.
