Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken by the wide angle context camera on Mars Reconnaissance Orbiter (MRO) in April 2019. It shows an area on Mars where a number of meandering curving channels flow downhill from the west to the east.

Earlier MRO images had already spotted these channels, so when this context image was taken the scientists also took a high resolution image of the same channels, with the white box indicating the area covered by the rotated, cropped, and reduced image below.

Both images are today’s MRO image of the day, where the MRO team notes that “The objective of this observation is to examine a complex network of channels. Some parts of the channels are quite curved.”

Astra launch failure caused by one of five 1st stage engines shutting down at liftoff

8:57 am

Capitalism in space: According to an Astra press release, its launch failure on August 28th was caused when one of the rocket’s five 1st stage engines shut down one second after liftoff.

One of the five main engines shut down less than one second after liftoff, causing the vehicle to slowly lift off the pad before resuming its trajectory. After approximately two minutes and thirty seconds of flight, the range issued an all engine-shutdown command, ending the flight.

The lack of one engine explains the rocket’s strange take-off, where it initially tilted slightly, shifted sideways, and then straightened up and began rising upward. From that point onward the ground controllers knew the mission would not reach orbit, and were only waiting until it reached a safe altitude to cut off the engines and have the rocket fall into the ocean safely.

While the launch failed, Astra’s engineers should be very satisfied by how the software on the rocket functioned. Rather than shut everything down and crashing into the launchpad fully fueled where it could do a lot of damage, the rocket immediately compensated for the loss of one engine and resumed a stable flight, allowing it to get clear.

This success does not negate the failure however. Astra needs to find out why one engine shut down.

SpaceX successfully launches cargo Dragon to ISS

12:35 am

Capitalism in space: SpaceX tonight successfully used its Falcon 9 rocket to launch cargo Dragon to ISS.

The first stage completed its fourth flight, landing successfully on the drone ship in the Atlantic. The cargo Dragon is making its second cargo mission for NASA. It will dock tomorrow.

This was SpaceX’s first launch since June 30th, a gap of almost two months as they initiated operations of a new drone ship in the Atlantic and shifted an older drone ship to the Pacific. In the next few weeks expect their fast launch pace for ’21 to resume, with at least one Starlink launch and the September 15th Inspiration4 commercial manned orbital flight.

The leaders in the 2021 launch race:

29 China
21 SpaceX
13 Russia
4 Northrop Grumman

The U.S. now leads China 32 to 29 in the national rankings.

Astra third launch attempt fails just before 1st stage engine cutoff

3:57 pm

Astra launch, August 28, 2021

Capitalism in space: The third orbital launch attempt of the smallsat rocket company Astra failed about two and a half minutes into flight, just about twenty seconds before the the first stage engine cutoff and stage separation.

It appeared that the first stage engines shut down about twenty seconds early, and then the rocket began tumbling.

I have embedded the live stream below the fold, cued to just before launch. The image to the right is a screen capture about seven seconds after liftoff. Astra’s rocket did a maneuver at launch I’ve never seen before, where it immediately tilted slightly to transition to the side, and then righted itself to begin gaining altitude. In this image the top of the strongback can be seen on the left, with the now upright rocket beginning its flight.

Whether Astra can figure out what went wrong and attempt another flight before the end of this year remains unclear. This was the third launch in their announced three launch test program, with the goal of reaching orbit on the third launch (today’s). They did not meet that goal, though their second test launch in December came extremely close to orbit with no major technical failures.

Successful orbital engineering test of magnetic space junk removal technology

10:34 am

Capitalism in space: The Japanese-based company Astroscale has successful completed its first test in orbit of a magnetic capture device designed to someday remove for space junk.

Launched on March 22, ELSA-d (short for “End-of-Life Services by Astroscale demonstration”) brought with it to orbit a 37-pound (17 kilograms) cubesat fitted with a magnetic docking plate. During the experiment on Wednesday (Aug. 25), ground controllers first remotely released a mechanical locking mechanism attaching the cubesat to the main 386-pound (175 kg) removal craft, Astroscale said in a statement. The two satellites were still held together by the magnetic system, which is responsible for capturing the debris.

The cubesat was then released completely and recaptured before floating too far away from the main spacecraft. Astroscale said on Twitter that this maneuver was repeated several times. This short demonstration enabled Astroscale to test and calibrate rendezvous sensors, which enable safe approach and capture of floating objects.

Engineers in the coming weeks plan to do even more challenging tests of ELSA, including a capture attempt where the target is made to tumble like an out-of-control satellite.

Eventually the company hopes to sell its target technology to satellite makers so that its satellites will be able to capture them. It already has a deal with OneWeb to develop this technology for its satellites, whereby one of its clean-up satellites could capture a bunch of defunct OneWeb satellites on one flight and deorbit them safely.

Whether this magnetic capture technique could be used on satellites with metal but no specifically designed target is unclear. If so it would place Astroscale a strong position to gain a large portion of the space junk removal business.

George C. Scott’s Patton speech

6:01 pm

An evening pause: The opening speech from the 1970 movie Patton that captured the character of one of America’s most unique and successful generals.

Patton was a difficult man with little diplomacy, but then, soldiers are not hired to be diplomats. (At least we didn’t when America was the sane country of courageous fighters, as described in this speech.) Yet, as difficult as he was, his philosophy of war was a direct descendant of the war strategy and tactics of Ulysses S. Grant. As Patton is believed to have actually said,

“Our basic plan of operation is to advance and to keep on advancing regardless of whether we have to go over, under, or through the enemy. We are going to go through him like crap through a goose!”

This was how Grant won the Civil War. It was how Americans fought every war that followed through World War II. Sadly, that philosophy was lost by the bureaucratic military that developed during the Cold War.

If only we had generals and political leaders today who understand this utterly essential approach for winning wars.

One note: The speech’s language at times violates my rules about obscenities. In the context of war and death however I think the use of such language wholly appropriate.

Hat tip Daniel Morris.

Sweden — land of no lockdowns or mandates — is doing best of all European nations against COVID

4:44 pm

Present European statistics on COVID
Click for full image.

Sweden has been slammed repeatedly by our panic-stricken mob of elitist leaders in politics, academia, and journalism for refusing to impose lockdowns or mask mandates. Instead, they essentially followed the recommendations of the Great Barrington Declaration and focused on protecting the vulnerable (the old and sick) while allowing everyone else (the young and healthy) to live normal lives. (This approach is what western civilization had done for the last two centuries when faced with a new flu epidemic, and only abandoned it in 2020 when our new leftist masters decided they knew better.)

The result was that the COVID virus quickly spread through Sweden’s strong and healthy population, did little harm, but left behind a nation of people who all have a natural immunity to the Wuhan flu and its later strains. Thus, while the rest of Europe — home of totalitarian and mindless governmental restrictions, lockdowns, mask and vaccine mandates — is now dealing with new outbreaks of the Wuhan flu and new deaths, Sweden is not.

The chart above, from the European Centre for Disease Prevention and Control and annotated by Doug Ross, illustrates this starkly. He also notes this disgusting fact about the bankrupt journalists of today:

It took me well more than 12 seconds to find the website of the European Centre for Disease Prevention and Control, where weekly Covid updates from each country are tabulated. That level of effort finding the numbers apparently is too difficult for Pro Journalists at the HDNY Times*, CCNN, NBS, Politishmo, Yapoo and the rest.

Natural immunity is the best way to protect against the arrival of new flu strains. The drugs that have been developed might do okay, but against respiratory diseases like the coronavirus they have never been a real solution, only a bandaid that is best reserved for that old and sick population who really needs it. This is why we have always advised older people to get flu shots, but not the young.

Today’s blacklisted American: Conservative student disqualified from student government because he’s conservative

1:22 pm

No free speech at Auburn University
No freedom of speech allowed at Auburn University!

The new dark age of silencing: A conservative student at Auburn University was voted down for government office essentially because it was revealed that he was conservative and Christian, and had expressed entirely reasonable views on Twitter criticizing the Black Lives Matter movement and its racist and Marxist agenda.

A junior nominated for a position on Auburn University’s student government was successfully shot down because he expressed Christian and conservative beliefs on social media.

Stephen Morris was nominated for the position of chief justice of Auburn University’s Student Government Association. To his surprise, at the session where his nomination was to be taken up, held remotely over video, several members of the student senate strongly opposed his nomination.

Morris’s critics accused him of racism over tweets they found offensive, and declared him unfit for service in student government.

The story at the link provides three examples of Morris’s tweets. None show the slightest indication of racism, merely a strong opposition to the agenda of Black Lives Matter, which despite its name seems entirely disinterested in the terrible crime rate in black communities, where innocent blacks are daily killed and robbed by the black criminals in their midst. Instead, all BLM cares about is eliminating any police protection for those innocent blacks, and for gaining as power and money for itself.

Another mountain view from Curiosity

12:33 pm

Low resolution panorama
Click for full resolution panorama. The original images can be found here, here, here, here, here, and here.

I hope my readers won’t get tired of seeing these mountain views from Curiosity, but I can’t get enough of them.

The image above is a panorama I’ve created from six photos taken by Curiosity’s right navigation camera yesterday. The box marks the location of that spectacular outcrop I highlighted in the previous mountain view five days ago. The red dotted line shows the rover’s upcoming planned route. The white cross indicates the pavement bedrock where the science team hopes to next drill.

For scale, Navarro Mountain is rises about 400 feet from where the rover presently sits. The peak of Mount Sharp is actually not visible, blocked by its near white flank on the panorama’s left edge. That peak is still 13,000 feet higher up from where the rover presently sits.

The rise of rocks next to the words “entering Gediz Vallis” is actually only probably five to ten feet high, as it is very close to the rover.

Curiosity’s travels continue to get more and more exciting to follow.

FAA’s space bureaucracy chief touts desire to limit his agency’s regulatory fist

10:18 am

Wayne Monteith, the man in charge of the FAA’s office of commercial space — which is tasked with regulating commercial space — revealed in a speech on August 25, 2021 that his goal is to speed that industry’s growth, not hinder it with odious regulations.

Wayne R. Monteith, a retired Air Force general who served for years in space billets in Colorado Springs is now the FAA’s associate administrator for commercial space transportation. He told a Space Symposium crowd at The Broadmoor Wednesday that to a large extent, he’s trying to keep his agency out of the way of the rush to space. “A regulatory agency can either be an accelerator or an inhibitor of industry,” he said. “We choose to be an accelerator.”

Sounds good, doesn’t it? Don’t be so sure. While right now Monteith noted that the agency is taking a laissez-faire approach to anyone who wants to fly in space, acting only to make sure space accidents will not harm “the uninvolved public,” he also said this in his speech:

Monteith warned, though, that mishaps for manned space flight that escalate to what he called “catastrophe,” have consequences. “The worst case is a catastrophic failure,” he said. “Then, we will regulate.”

In other words, he recognizes that if he tried now to impose his bureaucratic will on commercial space, it would not fly politically. What he really needs to expand his power is some space accident, a crisis you might say, that he can then use to convince others that he should be controlling things more.

Based on the response of the press, public, and American culture in the past half century, his thinking is quite sound. Routinely since World War II, as soon as something goes wrong in any field of endeavor the American public and political class has repeatedly wanted the government to move in and take greater control, under the false premise that somehow the government can prevent further failures.

Instead, we have accomplished less, and fueled the rise of an all-powerful bureaucracy capable and quite willing to squelch achievement. This is the pattern that Monteith is relying on, and based on recent history, he is entirely justified in believing so.

China studying the construction of large-scale structures in space

9:57 am

The new colonial movement: China has now indicated that it has established a project to study methods for building very large structures in orbit, with uses ranging from generating beamed solar power to providing mega-sized manned spaceships and space stations.

Though vague, the project would have practical applications for potential megaprojects including colossal space-based solar power stations. Such facilities would be based in geostationary orbit and span kilometers. These stations would collect solar energy and transmitting power to Earth through microwaves.

Kilometer-scale, ultra-large spacecraft are described as “major strategic aerospace equipment for the future use of space resources, exploration of the mysteries of the universe, and long-term habitation in orbit,” according to the project outline within the mathematical and physical sciences attachment to the released document.

The project would focus on minimizing the weight of the spacecraft to reduce the number of launches and construction, according to an initial report by the South China Morning Post.

It appears that this project is only in its preliminary design phase, with a budget of $3.2 million. Its existence however reinforces the overall rational and long term approach China’s government is taking to space exploration. At this moment they mean business, and are focused on getting the cutting edge technology designed and built rather then maintaining a bureaucratic infrastructure and the jobs that go with it — as NASA and Russia have been doing for the past forty-plus years.

Rocket Lab becomes third rocket company to go public

9:46 am

Capitalism in space: On August 25, 2021 Rocket Lab became the third rocket company to go public, following Virgin Galactic and Astra to sign a merger deal with a special-purpose acquisition company (SPAC).

Nasdaq celebrated the milestone, inviting Rocket Lab founder and CEO Peter Beck to ring the market’s opening bell Wednesday morning.

The SPAC merger, with a San Francisco-based company called Vector Acquisition Corporation, provides Rocket Lab with about $777 million. The funds will aid the development of multiple projects, including Rocket Lab’s big, next-generation Neutron rocket, company representatives said.

Nor is this all. Virgin Orbit has also signed a similar deal this wee, and will begin trading stock soon.

All these deals indicate that the investment community is very confident in making big profits in space, and is now willing to commit a lot of cash to that prospect.

ULA to no longer sell Atlas-5 launches

9:36 am

Capitalism in space: In an interview ULA’s CEO Tory Bruno has announced that they have contracts on all of the company’s remaining Atlas-5 rockets, and will no longer be offering that rocket for new sales.

“We’re done. They’re all sold,” CEO Tory Bruno said of ULA’s Atlas V rockets in an interview. ULA, a joint venture between Boeing and Lockheed Martin, has 29 Atlas V missions left before it retires sometime in the mid-2020s and transitions to its upcoming Vulcan rocket, Bruno said. The remaining Atlas V missions include a mix of undisclosed commercial customers and some for the Space Force, NASA, and Amazon’s budding broadband satellite constellation, Project Kuiper.

This means that the company is now firmly committed to its Vulcan rocket, which also means it is entirely committed to the repeatedly delayed BE-4 engine that Blue Origin is building for that rocket. This announcement suggests that Bruno is confident that the BE-4’s problems have been overcome, and that Blue Origin is about to begin regular assembly of the many flightworthy engines ULA will need.

If so, this is really good news. It not only means that Vulcan launches will finally begin, but that Blue Origin might also begin flying its New Glenn rocket. Both will give the U.S. some competitive options for getting big payloads into space. Right now the only real choice at a reasonable price is SpaceX, and having one choice is never a good thing.

Amazon protests SpaceX’s Starlink plan to FCC

9:23 am

Amazon on August 25, 2021 filed a protest with the FCC against SpaceX’s proposed expansion of its Starlink constellation that would allow almost 30,000 satellites to be launched.

“Should the Commission depart from its rules and precedent and endorse the approach of applying for multiple, mutually exclusive configurations, the consequences will extend far beyond the SpaceX Amendment,” wrote Mariah Shuman, corporate counsel for Amazon’s broadband megaconstellation venture Project Kuiper, in an Aug. 25 letter to the FCC. “However inefficient this strategy might be for the Commission and parties responding to applications, other prospective licensees will surely see the benefit in maximizing their optionality by describing multiple configurations in their license applications.”

Shuman asked the FCC to “dismiss SpaceX’s Amendment, and invite SpaceX to resubmit its amendment after settling on a single configuration for its Gen2 System.”

It appears Amazon does not want the FCC to approve multiple proposed satellite configurations put forth by SpaceX in a single application. Instead, it wants the FCC to force SpaceX to pick one, and submit that alone. It also appears that doing what Amazon requests would be more in line with past FCC policy.

While Amazon might have a point, the optics once again make another Jeff Bezos’ company look ugly, more interested in using the courts to stymie its competitors than actually launching anything. Amazon’s Kuiper internet constellation was first proposed in early 2019. More than two years have passed and none of its more than 3200 satellites have launched — not even one test satellite — with no clear indication yet on when launches will finally begin.

SpaceX began testing its Starlink system in 2018, and already has about 1,700 operational satellites in orbit. The comparison between the two companies is stark, and not favorable to Amazon.

In fact, Elon Musk was not shy in taking advantage of these optics to note them quite sharply in a tweet yesterday, saying, “Turns out Besos [sic] retired in order to pursue a full-time job filing lawsuits against SpaceX.”

Amazon is not Blue Origin, but both companies were founded by Bezos, and it appears right now that both prefer court battles to rocket engineering.

Webb telescope finally completed, ready for shipment to launchpad

2:15 pm

After more than two decades of construction (ten years behind schedule) and more than $10 billion (20 times the original cost), the infrared James Webb Space Telescope has finally completed its testing and is ready for shipment to its launch site in French Guiana to be mounted on an Ariane 5 rocket.

Now that observatory testing has concluded, shipment operations have begun. This includes all the necessary steps to prepare Webb for a safe journey through the Panama Canal to its launch location in Kourou, French Guiana, on the northeastern coast of South America. Since no more large-scale testing is required, Webb’s clean room technicians have shifted their focus from demonstrating it can survive the harsh conditions of launch and work in orbit, to making sure it will safely arrive at the launch pad. Webb’s contamination control technicians, transport engineers, and logistics task forces are all expertly prepared to handle the unique task of getting Webb to the launch site. Shipping preparations will be completed in September.

If all goes well, NASA and ESA hope to launch the telescope in late October. It will then take about six months for the telescope to unfold and reach its operating position a million miles from Earth in the Earth’s shadow.

Let us all pray that everything works. If it does not, there will be nothing that can be done to fix it for probably at least five years, if then, as it will be out of reach of any maintenance mission, manned or unmanned.

Today’s blacklisted American: World’s top vaccine expert censored by Twitter & LinkedIn and punished by the CDC

12:14 pm

No real scientists allowed!
The opinions of real scientists banned!

They’re coming for you next: Even as Martin Kulldorff, a Harvard medical professor and one of the world’s foremost experts on vaccines, has been repeatedly censored by Twitter and LinkedIn, he has been banned and punished by the CDC for daring to publicly dissent from its government lockdown and mask and vaccine mandate policies.

First, I think it important to know who Martin Kulldorff is. This article provides a succinct resume of his qualifications:

Dr. Martin Kulldorff is a professor of medicine at Harvard Medical School and a biostatistician and epidemiologist at the Brigham and Women’s Hospital. He helped develop the CDC’s current system for monitoring potential vaccine risks.

Then there is this opinion by one of his collegues:

Kulldorff is a “world-class” vaccine safety “superstar,” said Jeffrey Brown, a Harvard Medical School colleague specializing in drug and vaccine safety research. “His qualifications are spectacular,” Brown said of Kulldorff. “He’s an international expert in vaccine safety. No one on earth would question whether he’s qualified. … He’s a pioneer.”

And yet, he has now become a pariah on social media as well as at the CDC, all of whom are apparently no longer interested in a robust and honest discussion about COVID.

ULA rolls Vulcan core first stage to launchpad for tank tests

9:26 am

Capitalism in space: ULA yesterday rolled out a test Vulcan core first stage to its launchpad for a variety of tests in preparation for its first launch, now delayed until next year.

The rocket’s core stage will undergo Pathfinder Tanking Tests (PTT) at Space Launch Complex-41 at Cape Canaveral Space Force Station. It is outfitted with two development BE-4 engines that will be replaced by flight engines before launch. The tanking, or fueling, tests will validate launch pad infrastructure, evaluate countdown procedures, and train the launch team.

That these launchpad tests were delayed until now suggests that ULA had hoped to do them with the flightworthy engines, and then follow-up quickly with Vulcan’s first orbital launch in the fall. With the admission this week by both Blue Origin and ULA that the flightworthy BE-4 engines would not be delivered this summer as promised, ULA probably decided it was better to get this testing done now with the development engines, in order to save prep time for when the flightworthy engines finally arrive.

Thus, the delays at Blue Origin are costing ULA money. Once the flightworthy engines are installed, ULA will still need to do static fire launchpad tests, which means they will have to do much of this test program all over again. The extra countdown rehearsals are of course beneficial, but they are an extra expense, and also require extra time.

ULA’s CEO, Tory Bruno, has tried very hard to streamline ULA’s operations so they are more efficient and thus more competitive. Blue Origin’s failure to deliver on time is making Bruno’s effort very difficult.

It also shows that SpaceX’s policy of building as many of its components in-house, instead of depending on outside contractors, makes sense. And that all of the new rocket companies are doing the same proves that others agree. ULA’s dependence on others for its rocket engines will thus in the long run put it at big competitive disadvantage.

Spanish judge invalids agreement to build TMT in Canary Islands

9:05 am

The consortium attempting to build the Thirty Meter Telescope (TMT), blocked by protesters in Hawaii, has now had its back-up location in the Canary Islands blocked by a Spanish judge, who last month invalidated the agreement between the consortium and local authorities.

[A]n administrative court in Santa Cruz de Tenerife, the capital of the Spanish archipelago, ruled last month that the 2017 concession by local authorities of public land for the tentative project was invalid. The ruling was dated on July 29, but only became public this week after local media reported about the decision.

In the ruling obtained by The Associated Press, Judge Roi López Encinas wrote that the telescope land allocation was subject to an agreement between the Canary Astrophysics Institute, or IAC, and the telescope’s promoter, the TMT International Observatory (TIO) consortium. But the judge ruled that the agreement was not valid because TIO had not expressed an intention to build on the La Palma site instead of at the Hawaii site.

In other words, it appears the agreement was ruled invalid because the TMT builders had not made a firm commitment about building at the Canary Islands.

At this moment it truly looks like TMT is dead. It has no alternative site, and its political support in Hawaii is nil. While the Democratic Party politicians that rule that state have mouthed support for it, almost all their actions since the protests began has been to help the protesters and stymie construction.

What I think will soon begin happening is that the partners in TMT will begin to back out, switching their support to the other large ground-based telescopes being planned, the Giant Magellan Telescope and the European-Extremely Large Telescope. Since these are both being built in Chile, the loss of TMT means that there will be no large ground-based telescope coverage of the northern sky.

The real solution? Stop building ground-based telescopes. Put them in space, where such political issues won’t exist, and the view will be unimpeded by either the atmosphere or the tens of thousands of new satellites expected to launch in the coming years.

Blue Origin successfully completes another unmanned suborbital flight with New Shepard

8:47 am

Capitalism in space: Only one month after its first passenger flight, Blue Origin today successfully completed another suborbital flight with its New Shepard booster/capsule, this time flying 18 commercial payloads for NASA and others.

These details about the spacecraft itself I think are significant:

The New Shepard booster, Tail 3, and its associated capsule, RSS H.G. Wells, flew the mission. Tail 3 is dedicated to uncrewed science missions like NS-17, and this was Tail 3’s 8th flight.

…Blue Origin expects to fly one more New Shepard mission this year with sister ship Tail 4 and the crew-capable capsule RSS First Step

In other words, Blue Origin now has two working New Shepard spacecraft. This will allow them to eventually up their launch pace.

Today’s blacklisted American gets an apology from Illinois regulators for threatening his medical license for opinions they didn’t like

2:39 pm

Today’s blacklist story is actually an update from my blacklist story two days ago about Dr. Jeremy Heinrichs, who because he had publicly expressed strong skepticism about the mask mandates being imposed by his state government in Illinois, had been threatened with the loss of his medical license by state regulators.

It appears those regulators have now quickly apologized for getting caught acting like jack-booted thugs.

“The initial response to your inquiry requested information that the Department does not need,” Dina Martin, an attorney with the Illinois Department of Professional and Financial Regulation, said in a letter to Henrichs’ legal counsel. The department had originally asked for “a detailed statement on your opinion about masks, and whether you support and will enforce a mask mandate based on your elected position as a school board member.”

“I sincerely apologize for the tone and content of those communications,” Martin said in her August 19 letter, obtained by Just the News.

It also appears that the regulators plan to drop their complaint investigation.

This is how you treat bullies. You don’t back down. You don’t apologize. And you certainly don’t hide in shame out of fear their unjustified attacks will hurt you. No, you fight back hard, and brightly expose them for all to see. Like all bullies they will immediately back off themselves, especially if their attack has no merit (which is almost always the case).

There is no indication however that the regulators who sent those improper initial communications have been punished in any way. I expect not. The Illinois government got caught this time, but has no intention of preventing this from happening in the future. If anything I expect the government has simply asked these employees to lay low for awhile and try the same thing again later, in the hope that others will be more easily intimidated.

To really fix this the voters need to fire everyone in these governments, from the Democratic Party elected officials who control Illinois to the lowest bureaucrat who thinks such behavior can sometimes be justified.

Perseverance’s upcoming targets: sand ripples, rocks, and a lot of dust

2:17 pm

Ingenuity's view during 12th flight

Cool image time! The photo to the right was one of ten color images taken by Ingenuity on its twelfth flight on August 15, 2021. This photo is one of two images looking the same area from slightly different positions in order to create a stereoscopic view, with the other image found here.

The ground the helicopter was scouting, dubbed South Seitah, is an area that the Perseverance team hopes to send the rover. Ingenuity’s images from this flight will not only tell them whether the terrain is safe to traverse, it will allow them to map out a route that will avoid problems while effectively targeting the most interesting rocks.

The photo shows a lot of Martian dust, with a good portion forming small sand dune ripples. The rocks appear to be bedrock pavement stones, which because these are on the floor of the crater and the lowest elevation, likely hold the oldest geology that Perseverance will see on its journey in Jezero Crater. For this reason the science team is spending a lot of time studying that floor, and will make probably several drilling attempts to obtain samples.

The terrain in general looks entirely safe for the rover to travel. I expect the science team will thus continue north, crossing to North Seitah, rather than backtrack and travel over already traversed ground. Initially they had decided to avoid this ground because they feared it might be too rough for the rover. I suspect they were just being overly cautious at the start of the mission, and will now work past that fear.

Musk’s Boring Co offers to dig tunnel for resident transportation during launch closures

1:49 pm

Capitalism in space: Elon Musk’s Boring Company has proposed digging a tunnel so that people can still access Boca Chica’s beaches even during periods when SpaceX is doing launch operations and needs to close the surface roads.

The Boring Company (TBC) met with Cameron County officials to discuss the possibility of a tunnel project running from South Padre Island (SPI) to Boca Chica Beach.

The Boring Company pitched the idea of an SPI-Boca Chica tunnel to Cameron County administrator Pete Sepulveda Jr. and county engineer Benjamin Worsham early this summer. Cameron County officials have been thinking of giving people access to part of Boca Chica Beach even during closures.

The county has said it likely cannot afford to pay for such a thing, but Musk’s company is still proposing to do an in-depth study to find out what will be necessary to make it happen.

It could very well be that Musk might find some cash to help pay for this himself. The public relations would be excellent, and it would I think be the right thing to do. It is also possible that the local communities will have more cash themselves because of the booming economy SpaceX is bringing them.

Blue Origin BE-4 engine delayed again

10:14 am

In an interview ULA’s CEO Tory Bruno revealed that Blue Origin is not going to deliver the first two flightworthy BE-4 engines this summer, as promised, with delivery now probably not until the end of the year.

“I will not get them before the end of the year,” said Tory Bruno, CEO of ULA, in an exclusive Denver Business Journal interview ahead of this week’s Space Symposium industry gathering in Colorado Springs. “It will be shortly into the beginning of the 2022 calendar year, and anywhere in there will support me being able to build up a rocket and have that Vulcan waiting on my customer, Astrobotic.”

…“We’ve actually be been able to accommodate this, but I’ll be straight with you, the dates we’ve set up for them now— we really don’t have the ability to make any big moves after this,” Bruno said. “I need them to diligently work through the plans we have and get done on time.”

ULA needs to launch its new Vulcan rocket twice in order to get approved for its first military launch, now expected in less than 12 months. They thus no longer have any schedule margin.

China completes two launches

2:23 pm

China today successfully completed two launches, using from different spaceports its Long March 2C and Long March 3B rockets.

The 2C launched a two demo internet communications satellites designed to eventually be used in a large constellation similar to the constellations of SpaceX and OneWeb. The launch also included a third unidentified communications satellite.

The 3B placed in orbit what is believed to be a military reconnaissance satellite.

Both rockets dumped their first stages somewhere in the interior of China. No word on whether those stages carried parachutes or grid fins to better control their landing, or crashed near habitable regions.

The leaders in the 2021 launch race:

29 China
20 SpaceX
13 Russia
4 Northrop Grumman

The U.S. still leads China 31 to 29 in the national rankings.
