Russian company S7 ends project to build private rocket

8:50 am

The Russian company S7 has ended its project to build a private rocket, citing lack of funds and a dearth of Russian investors.

Due to a lack of opportunity to raise funding, the project to create a light-class carrier rocket has been suspended,” the press service said.

The company said that was the reason why it let go some of its staff – 30 people out of more than 100 – in June. “Still, S7 Space continues to operate in some areas, such as additive and welding technologies where work is underway,” it said.

S7 first announced this rocket project in 2019. Development was suspended in 2020, however, when the Putin government imposed new much higher fees on the company for storing the ocean launch platform Sea Launch, fees so high that the company was soon negotiating to sell the platform to a Russian state-run corporation.

At the moment it appears that while Russia has possession of the Sea Launch ocean floating launch platform, it has nothing to launch from it. Nor does there appear to be any Russia project that might eventually do so. The Putin government has quite successfully choked off S7 — fearing the competition it would bring to Roscosmos — and with it any other new rocket company.

France signs Artemis Accords

8:35 am

The U.S. State Department yesterday announced that France has become the twentieth nation to sign the Artemis Accords.

The full list of signatories so far: Australia, Bahrain, Brazil, Canada, Columbia, France, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Poland, Romania, Singapore, South Korea, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

France’s signing is a major breakthrough, as both it and Germany, major players in the European Space Agency, have appeared to resist signing on because to do so would have limited their ability to partner with Russia on space projects (Russia opposes the accords). The Ukraine War has apparently ended France’s resistance. It no longer has any partnerships with Russia, and is not likely to form any new ones in the near future.

We should expect Germany to sign on in the near future as well.

As I wrote in May, the future factions in space are now becoming clearer. On one side we have the American Alliance, signers of the accords who support private property. On the other we have Russia and China, who oppose the accords because they also oppose private property.

In May I also included a third faction, made up of non-aligned space powers. That faction now appears to be fading away, though it still includes Germany and India.

Today’s blacklisted American: Georgetown University succeeds in blacklisting conservative for having opinions

12:04 pm

Georgetown University: No free speech allowed

They’re coming for you next: Though Georgetown University announced last week that it had finally decided to reinstate Ilya Shapiro as a senior lecturer and executive director for the university’s Georgetown Center for the Constitution, Shapiro responded almost immediately by announcing his resignation from the job.

Shapiro had been suspended and under investigation for the past four months because of a single tweet he had issued criticizing President Biden’s decision to make race and gender more important than a judge’s legal qualifications in picking Ketanji Brown Jackson for the Supreme Court. For the background to this story see my May 13, 2002 post.

Shapiro’s resignation letter to William M. Treanor, Dean & Executive Vice President of the law center (available at the second link above), makes clear his reasons for quitting:

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

The Ukraine War: After a third month of fighting the battlelines clarify

The Ukraine War as of May 5, 2022
The Ukraine War as of June 6, 2022. Click for full map.

With more than three months of fighting since Russian began its unprovoked invasion of the Ukraine in late February and a full month since my last update on May 6th, it is time to do another follow-up to get a clear assessment of the war.

The two maps to the right are simplified versions of those produced daily by the Institute for the Study of War (ISW). For their full interactive version go here. The top map comes from its May 5th assessment, while the bottom map comes from its assessment on June 6th. The red hatched areas are regions Russia captured in 2014. The red areas are regions the Russians have captured in this invasion and now fully control. The pink areas are regions they have occupied but do not fully control. Blue regions are areas the Ukraine has recaptured. The blue hatched area is where local Ukrainians have had some success resisting Russian occupation.

Though the changes since early May are small, they make clear that the war’s battlelines have now become very clear. While Russia is very slowly but successfully taking ground in the center regions of its invasion, the Ukraine has been just as slowly but successfully retaking territory at the invasion’s outer edges.

France re-approves Starlink service

8:56 am

Capitalism in space: After finally completing what France’s telecom bureaucracy ARCEP calls “a public consultation,” the French government once again approved Starlink service on June 2nd.

ARCEP had authorized Starlink in February 2021, however, France’s highest administrative court revoked the license April 5 after ruling that the regulator should have first launched a public consultation.

That ruling came after two French environmental activist organizations submitted an appeal to challenge Starlink’s frequency rights, citing concerns including the impact of megaconstellations on views of the night sky and space debris.

This approval, combined with recent approvals of Starlink in the Philippines and Nigeria, continues the steady expansion of Starlink service globally.

Woman arrested for trespassing at SpaceX’s Boca Chica facility

8:45 am

A Pittsburgh woman, Nivea Rose Parker, 20, was arrested on June 1, 2022 while trespassing at SpaceX’s Boca Chica facility.

SpaceX security personnel informed deputies a woman, later identified as Parker, was roaming around the fifth floor of the High Bay #1 building. Parker claimed to be an employee of SpaceX and wanted to speak to Elon Musk, security said. [emphasis mine]

Very little additional information has been made available. However, that Parker could get so far into one building, where rockets are assembled, is quite worrisome, considering the “hate Musk” campaign that is growing on the left. These people willfully riot and bomb facilities. SpaceX must take this trespass as a warning that worst could happen if it doesn’t tighten security at all its facilities, especially Boca Chica.

Fuel leak scrubs launch of Dragon cargo capsule this week

8:52 pm

A fuel leak detected during fueling of hydrazine in a Dragon cargo capsule as it was being prepared for a June 10th launch has forced SpaceX and NASA to delay the launch.

SpaceX detected “elevated vapor readings” of monomethyl hydrazine, or MMH, fuel in an “isolated region” of the Dragon spacecraft’s propulsion system during propellant loading ahead of this week’s launch, NASA said in a statement.

The fueling of the Dragon spacecraft is one of the final steps to prepare the capsule for flight, and typically occurs just before SpaceX moves the craft to the launch pad for integration with its Falcon 9 rocket.

The Dragon spacecraft has propellant tanks containing hydrazine fuel and nitrogen tetroxide oxidizer. The two propellants ignite upon contact with each other, providing an impulse for the cargo ship’s Draco thrusters used for in-orbit maneuvers.

Each Dragon spacecraft has 16 Draco thrusters, small rocket engines that generate about 90 pounds of thrust. The Draco engines are used for orbit adjustment burns and control the spacecraft’s approach to the space station, then fire at the end of the mission for a deorbit burn to guide the capsule back into the atmosphere for re-entry and splashdown.

According to the article, it is not yet confirmed that the leak came from the capsule. If so, however, it could become a more serious issue, especially with the recent story — denied strongly by NASA — that a hydrazine leak caused damage to the heat shield of Endeavour during the return of its Axiom commercial passenger flight.

Spiders galore on Mars!

2:36 pm

Spiders galore on Mars
Click for full image.

Cool image time! The photo to the right, cropped to post here, was taken on February 27, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and shows a nice collection of what scientists have informally (but permanently) labeled as spiders, strange formations that exists only in the regions of the Martian south pole.

The spiders are believed to have formed because of the coming and going of the dry ice mantle in the polar regions that falls as snow in the winter and then sublimates away come the spring. Because dry ice is mostly clear, the spring sunlight penetrates it and warms the underlying surface, which acts to warm the base of the dry ice mantle. CO2 gas builds up, trapped below the dry ice, until the pressure causes it to break the dry ice at a weak point and spew outward, carrying with it dust that blackens the surface above. You can see three examples in today’s image.

Spiders however only happen at the south pole. In the north much of the terrain is formed by unstable dunes, which change from year to year, thus causing the gas breakage to occur at random and different spots.

In the south however the terrain is more stable, a surface of ice and dirt. The spiders form because the trapped gas always follows the same path from year to year to the same weak points, carving riverlike tributaries until these feeders combine and build up enough gas pressure to crack the overlying dry ice so that the gas can escape.

Though the gas functions much like a river of water, it has one fundamental difference that makes this phenomenon wholly Martian and quite alien. On Earth rivers flow downhill. On Mars, the gas in these spider tributaries is flowing upward, seeking a path into the atmosphere above.

Victory against blacklisting: School district drops attempt to punish children for using wrong prounouns

1:04 pm

Owned by government
Despite its legal defeat, this is still what the Kiel school district
in Wisconsin thinks of the kids it teaches.

Bring a gun to a knife fight: In another victory against the blacklisting culture that wants to destroy all freedom in the U.S., the threat of a lawsuit from parents has forced the Kiel Area School District in Wisconsin to abandon its effort to punish three eighth grade children for daring to use the wrong pronouns.

The original story was posted here on May 16, 2022. At the time, the Wisconsin Institute for Law and Liberty (WILL), which represented the parents, had sent a letter [pdf] to the school district, threatening it with a lawsuit if it did not drop its case.

After some failed attempts by the school district to negotiate a settlement, WILL announced on June 2nd its total victory.

In recent weeks, the District proposed various resolutions, but all within the Title IX framework. WILL and the families remained resolute in their position that the Title IX investigation was inappropriate and should be dismissed. WILL issued a follow-up letter to the District on June 2, making this clear. Hours later, the District relented and sent letters to the boys while announcing the investigation was “closed.”

It is worthwhile to read the Kiel school district’s own letter [pdf] announcing its decision to abandon this witchhunt against little kids. The letter’s first few paragraphs illustrate the district’s unwillingness to change any of its policies that push the queer sexual agenda, while also revealing a clear and continuing hostility to both these kids and their parents.

China launches three astronauts to Tiangong station

8:42 pm

The new colonial movement: Using its Long March 2F rocket, China has successfully launched three astronauts into orbit for a six month mission to its Tiangong space station.

The crew will be transported to the station in China’s Shenzhou capsule, docking about six hours after launch. During this mission China will also launch the last two large modules planned for the station, completing its initial construction by the end of the year.

I have embedded the live stream below the fold, cued to just before launch.

The leaders in the 2022 launch race:

22 SpaceX
18 China
8 Russia
3 Rocket Lab
3 ULA

The U.S. still leads China 31 to 18 in the national rankings, as well as the entire globe combined, 31 to 29.

Russia to take control of German telescope on space orbiter

9:12 am

Dmitry Rogozin, the head of Roscosmos, revealed today that he has issued orders for the scientists running the Spektr-RG telescope to figure out how to take over operations of the German instrument on the telescope.

“I gave instructions to start work on restoring the operation of the German telescope in the Spektr-RG system so it works together with the Russian telescope,” he said in an interview with the Rossiya-24 TV channel.

The head of Roscosmos said the decision was necessary for research. “They – the people that made the decision [to shut down the telescope] don’t have a moral right to halt this research for humankind just because their pro-fascist views are close to our enemies,” he said.

The Europeans had shut down operations when it broke off all of its space partnerships with Russia, following the Ukraine invasion and the decision of Russia to confiscate 36 OneWeb satellites rather than launch them as it was paid to do.

The oppressive and ignorant blacklisting culture that now dominates politics

12:50 pm

Most of all beware this boy.’
As noted by the Spirit of Christmas Present in Dickens’
The Christmas Carol, ‘This boy is ignorance, this girl is want.
Beware them both, but most of all beware this boy.’

While today’s blacklisting essay is mostly about one specific story, what it really does is illustrate starkly the overall ugliness and ignorance that fuels the blackballing, and how that ugliness and ignorance has seeped into every aspect of our political and cultural lives.

In a story that is hardly unique or surprising, the Los Angeles City Council last week passed a new regulation that bans the use of any gas appliances in new construction, both residential and commercial.

The council’s reasons for imposing this ban — as is usual for such bans — was based not on any actual documented problem that presently exists but on a fear that one might someday occur. From the opening paragraph of the actual motion:

As the gravity and urgency of the climate emergency become more apparent with each passing year of rising temperatures, dangerous wildfires, and more severe droughts—all of which disproportionately impact communities of color and the most vulnerable Angelenos—the City of Los Angeles must do all in its power to reduce its carbon emissions and move toward a sustainable, zero-carbon economy.

A look at World View, one of two balloon companies about to offer high altitude tourist flights

11:09 am

An artist's impression of a Worldview tourist balloon in flight
An artist’s impression of a World View tourist balloon in flight

The future of space tourism is not going to be limited to rockets, no matter how romantic those rockets might be. For a lot of people, getting into space might not be a good option simply because of cost. Moreover, even if one could afford the cheaper suborbital flights presently offered by Blue Origin and are promised someday from Virgin Galactic, the short length of the journey, no more than ten minutes in space, could for many people make these flights not worth doing.

There is an alternative however, one that won’t get you into space, but will fly you high enough that you will be above 90% of the atmosphere, see the curve of the Earth, and get to do it for hours for far less money. This alternative comes from the high altitude balloon companies that are now working hard to begin flying tourists sometime in the next two years.

There are presently two American companies on the verge of flying tourists to up about 20 miles altitude. One is Space Perspective in Florida. If all goes as planned, it will begin flying passengers on its Neptune balloon by ’24, at a ticket price of $125K per head. It is presently accepting reservations with a $1,000 deposit.

The second company is Tucson-based World View. Up until 2019 the company had been planning to fly tourists, but a change in leadership brought on by its failure to meet the terms of a local development deal caused it to put those plans aside. Then in 2021 it restarted those plans.

Tickets will cost $50,000 per person, with World View providing what it calls “flexible financing options.” The company expects the first flight no earlier than early 2024.

At the moment about 1000 people have put down a deposit of $500 for a flight.

Both companies will be offering flights lasting most of one day, with additional pre- and post-flight activities.

On May 18, 2022, I attended an event held by World View at its Tucson headquarters. The event showcased the company’s talent, its facilities, and the value of hi-tech high stratospheric balloons. To begin the event, CEO Ryan Hartman gave a short presentation describing his goals for the company and the strategy he is following to reach them. The two graphics below come from that presentation, and provide I think the clearest outline of those goals and strategy.

Sunspot update: In May we had sunspots, sunspots, and more sunspots!

10:31 am

It is time for another sunspot update! On June 1 NOAA released its monthly update of its graph tracking the number of sunspots on the Sun’s Earth-facing hemisphere. As I do every month, I have posted it below, having added some addition details to provide a larger context.

In May the sunspot activity on the Sun almost literally exploded, producing some of the strongest solar flares in years as well as the most sunspots since the previous solar maximum in 2014. On several days there were as many as eight sunspot groups on the Sun, with one so large that it was visible to the naked eye on Earth (if viewed properly with a protective filter).

Today’s blacklisted American: Teacher fired in retaliation for speaking out at school board meeting

Parent blacklisted for opposing school giving porno to kids
Blacklisted for opposing her school from giving porno to kids

They’re coming for you next: Brenda Danielle Reprieto, a substitute teacher in Georgia, was fired the day after she spoke out at the Cherokee County School District’s (CCSD) school board meeting, publicly criticizing the board for its policies.

Reprieto attended the meeting both as a teacher and as a parent of one of the district’s students. The topic of controversy was the porno that the school board was allowing in its elementary school libraries — for little kids to read — that was so vile the school board’s chairwoman, Kyla Cromer, would not allow it to be read aloud to adults. It was also considered too obscene for the parent, Chelle Brown, to email the text to the board members. As Brown noted at the beginning of her presentation, all her emails bounced because, as she noted “the content was so vulgar.” Watch her get cut off by the board:

India’s first private satellite manufacturing facility opens

10:31 am

Capitalism in space: At a ceremony today that included officials from the government, the private commercial company ANANTH opened India’s first private satellite manufacturing facility.

Located at Karnataka Industrial Area Development Board Aerospace Park, Bengaluru, the new establishment is equipped with clean rooms for spacecraft sub-systems manufacturing and is large enough to cater to four spacecraft simultaneously.

This unveiling is part of India’s effort to transition from a government-built space effort to one run by the private sector. In the past all satellite construction in India was designed, managed, and owned by India’s space agency ISRO. This facility will now take over that function, and do so not only for ISRO but for any private company that wishes to have a satellite built.

A rock stows away on Perseverance

10:24 am

Perseverance's stowaway
Click for full image.

Since early February the Mars Rover Perseverance has been toting with it a small rock in its front left wheel, as shown in the image to the right, cropped and reduced to post here and taken by the rover’s left hazard avoidance camera on February 6, 2022.

From an update today by the Perseverance science team:

Back on sol 341— that’s over 100 sols ago, in early February— a rock found its way into the rover’s front left wheel, and since hitching a ride, it’s been transported more than 5.3 miles (8.5 km). This rock isn’t doing any damage to the wheel, but throughout its (no doubt bumpy!) journey, it has clung on and made periodic appearances in our left Hazcam images.

You can see the most recent photo of the rock, taken on May 26, 2022, here. It is very clear that the rock’s repeated tumbling inside the wheel well has worn away its sharp edges as well as reduced its overall size. Given enough time its surface could even become somewhat smooth.

As the update notes, when this rock finally drops off it will create a potential mystery for future geologists, who if they are not aware that Perseverance moved it, will wonder how it got where it was, being geologically out-of-place in its new location.

NASA awards Axiom & Collins Aerospace contracts to build spacesuits

10:07 am

Capitalism in space: NASA yesterday awarded separate contracts to two different companies, Axiom and Collins Aerospace, to build spacesuits for its astronauts, either when they do spacewalks in space or when they are exploring the lunar surface.

The contract enables selected vendors to compete for task orders for missions that will provide a full suite of capabilities for NASA’s spacewalking needs during the period of performance through 2034. The indefinite delivery and indefinite quantity, milestone-based xEVAS contract has a combined maximum potential value of $3.5 billion for all task order awards. The first task orders to be competed under the contract will include the development and services for the first demonstration outside the space station in low-Earth orbit and for the Artemis III lunar landing.

Each partner has invested a significant amount of its own money into development. Partners will own the spacesuits and are encouraged to explore other non-NASA commercial applications for data and technologies they co-develop with NASA.

More information can be found in each companies’ press release, located here (Axiom) and here (Collins).

These commercial contracts replace NASA’s own failed effort to make its own Artemis spacesuits, which spent fourteen years and more than a billion dollars before being abandoned by the agency because wouldn’t be able to deliver anything on time.

The contracts also continue NASA’S transition — as recommended in my 2017 policy paper Capitalism in Space [pdf] — from a failed space contractor to merely being the customer buying products from the commercial sector. The result is we now have a vibrant and ever growing private space sector with products available quickly and cheaply not only for NASA, but for others. The Axiom press release illustrates these facts with this quote:

The Axiom spacesuit is key to the company’s commercial space services. This new NASA contract enables Axiom to build spacesuits that serve the company’s commercial customers and future space station goals while meeting NASA’s ISS and exploration needs.

SpaceX wins more NASA manned flights to ISS

9:52 am

Capitalism in space: NASA has now announced that it is buying five additional manned missions to ISS from SpaceX, beginning in ’26.

This new contract is in addition to a February ’22 NASA award that purchased three more Dragon flights.

After a thorough review of the long-term capabilities and responses from American industry, NASA’s assessment is that the SpaceX crew transportation system is the only one currently certified to maintain crewed flight to the space station while helping to ensure redundant and backup capabilities through 2030.

The current sole source modification does not preclude NASA from seeking additional contract modifications in the future for additional transportation services as needed.

The press release repeatedly makes it clear that NASA very much wishes to buy tickets on Boeing’s Starliner, but until it is declared operational it must give its business to SpaceX. Once Starliner begins flying, NASA will then buy seats on it and alternate between the two companies. Until then however this new SpaceX contract guarantees NASA enough flight capacity to keep ISS occupied, even if Starliner gets further delayed.

Regardless, Boeing has once again lost business to SpaceX because its Starliner capsule is not yet ready. In the long run this contract means fewer total flights for Boeing to ISS, which means less profits.

MAVEN returns to full operation

9:42 am

NASA announced yesterday that engineers have finally completely restored its Mars orbiter MAVEN, after a three month period when the spacecraft was in safe mode due to an attitude control problem.

To fix the problem engineers uploaded new software that allowed the spacecraft to determine its orientation in space not from its onboard inertial units, but from locking onto stars in the sky.

All instruments were healthy and successfully resumed observations; however, the spacecraft was constrained to pointing at the Earth until testing of all-stellar mode was completed, so the instruments were not oriented as they normally would be during science operations. Nevertheless, some limited science was still possible, and MAVEN even observed a coronal mass ejection impact Mars less than two days after the instruments were powered on.

Moreover, for some parts of the year it will still need its inertial units, so a fix for those time periods is still required.

Regardless, MAVEN can now resume acting as a communications relay between the Earth and the rovers on Mars, which for the past year has become its prime mission. While both rovers can communication without that relay, it is often necessary depending on a number of factors, and it also provides redundancy and a greater communications capacity.

Ursa Major announces new rocket engine to replace what Russia previously provided

9:32 am

Capitalism in space: The new rocket engine company Ursa Major yesterday announced a new more powerful rocket engine, dubbed Arroway, designed to replace rocket engines that Russia had been selling.

Arroway is a 200,000-pound thrust liquid oxygen and methane staged combustion engine that will serve markets including current U.S. national security missions, commercial satellite launches, orbital space stations, and future missions not yet conceived. The reusable Arroway engine is available for order now, slated for initial hot-fire testing in 2023, and delivery in 2025.

Notably, Arroway engines will be one of very few commercially available engines that, when clustered together, can displace the Russian-made RD-180 and RD-181, which are no longer available to U.S. launch companies.

Arroway could replace the RD-181 engines that Northrop Grumman uses on the first stage of its Antares rocket. Both engines are comparable in size. However, with Arroway available no sooner than ’25 it still will leave a gap, since right now the company only has enough stock on hand to launch two more rockets, both of which should launch before ’24.

Arroway is also about half as powerful as Blue Origin’s BE-4 engine, so if ULA wishes to use it in its Vulcan rocket a major redesign would be required.

Either way, Ursa Major is demonstrating here again the value of freedom and competition, as well as the foolishness and negative consequences of Russia’s invasion of the Ukraine. In response to the international sanctions against it, Russia blocked future rocket engine sales to the U.S. Not only did that not get the sanctions lifted, Russia is now losing that U.S. business, as other American companies are stepping up to replace it.
