Commercial Orbital Reef space station passes NASA’s design review

9:30 am

Proposed Orbital Reef space station

Capitalism in space: A proposed commercial space station dubbed Orbital Reef and being built by a partnership led by Sierra Space and Blue Origin has passed its NASA’s design review, allowing for construction to now begin.

The review, conducted as part of a $130 million development contract from NASA, found no issues with the station’s design.

This commercial partnership also includes Boeing, Redwire, Mitsubishi, Genesis Engineering, and Arizona State University, and plans its launch before 2030 when ISS will be retired. This quote from the article I think is important:

“We’re going as fast as we can,” Steve Lindsey, chief strategy officer at Sierra Space, said during a panel at the Goddard Memorial Symposium March 25. “We don’t want to have a gap like we did with crew back in the last decade.”

Three other private space stations are also under construction or being planned, all hoping to be operational prior to ’30. If even two of these launch, the 2030s will be very exciting indeed.

Astronomers discover a solar twin whose sunspot cycle changed into a grand minimum

9:19 am

Astronomers studying the sunspot cycle of several dozen stars that are twins of our Sun have identified for the first time a star whose 17-year cycle suddenly ceased, going into an extended grand minimum.

Comparing these stars to the Sun enables astronomers to better determine how typical – or not – the Sun is as a star. The Sun’s magnetic activity is defined by its 11-year sunspot cycle. Of the 59 stars that Baum’s team surveyed, 29 appeared to also have starspot cycles, and the period of those cycles could be measured for 14 of them.

“Of these 14 stars, the average length of their cycle is just under 10 years, which is similar to the Sun’s 11-year cycle,” Baum tells Physics World. However, not all the stars adhered to this time frame. One star that was surveyed has a cycle lasting less than four years, while another star, HD 166620, had a cycle 17 years long.

Note the past tense. Sometime between 1995 and 2004, HD 166620’s starspot cycle simply stopped.

When or if the star’s sunspot activity resume is unknown. The Sun’s last grand minimum, dubbed the Maunder Minimum, lasted 70 years during the 1600s.

No one yet understands why stars do this. This discovery however now shows that the Sun is not unique in this behavior.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Rocket Lab to attempt 1st stage recovery by helicopter on next launch

9:11 am

Capitalism in space: Rocket Lab will attempt during its next launch later this month to become the second commercial rocket company, after SpaceX, to successfully recover a first stage for reuse.

The company will use a customized Sikorsky S-92 helicopter to rendezvous with the stage as it descends slowly using parachutes and capture it. The helicopter will then fly it back to land and safely deposit it on the ground.

This launch is now scheduled for April 19th, at the earliest.

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.

Ingenuity completes its 24th flight on Mars

9:14 pm

Overview map
Click for interactive map.

Ingenuity today completed its 24th flight on Mars, traveling a short 33 feet for 69.5 seconds in order to place it in a good position for an upcoming record-setting 25th flight.

With Flight 24 in our log book, it is now time to look forward to our upcoming effort that charts a course out of Séítah. Flight 25 – which was uplinked yesterday – will send Ingenuity 704 meters to the northwest (almost 80 meters longer than the current record – Flight 9). The helicopter’s ground speed will be about 5.5 meters per second (another record) and we expect to be in the rarefied Martian air for about 161.5 seconds.

The red dot on the map to the right indicates Perseverance’s present position. The green dot shows where Ingenuity landed today. The tan dashed lines indicate the planned routes for both. Ingenuity’s next flight will take it out of the rough terrain of Seitah and much closer to Three Forks.

Sonny & Cher – I Got You Babe

6:01 pm

An evening pause: This performance, from 1987, has some important historical background. As noted on the youtube page,

In November of 1987, Sonny Bono was running for mayor of Palm Springs and Cher was promoting her upcoming movie Moonstruck. The divorced couple went on Letterman together and were coaxed into playing ‘I Got You, Babe’ with Paul Shaffer and his band; they weren’t exactly the best of friends at this point, but both of them knew it would make for unforgettable television. Had YouTube existed back then, this would have gone insanely viral the next morning. It wound up being the final time they ever sang together, as Bono passed away in January 1998.

Today’s blacklisted American: Whites aggressively blocked from attending health dept meeting

1:14 pm

Jim Crow celebrated in Seattle!
The return of Jim Crow, this time celebrated in the north, in Seattle!

“Segregation today, segregation tomorrow, segregation forever!” Seattle health administrators purposely organized an employee Zoom training session for minorities only, then aggressively banned any white staffers from attending, and then lied repeatedly about their actions and the segregated and illegal nature of the session.

The subject of the session was in itself bigoted, as it made the claim that dieting is a white racist strategy to harm blacks.

The King County Department of Human Resources announced the remote workshop, “Anti-Blackness and Diet Culture,” in an all-staff email newsletter. It was part of the county’s Balanced You program, which focuses on staff wellness. Tacoma-based Liberating Jasper, which conducted the workshop, claims dieting is harmful to black people, and that “Western ideals of attractiveness and health are steeped in whiteness.” It even implies that obesity can be healthy.

Despite claims to the contrary, the workshop intentionally excluded white people. Indeed, the event was promoted both publicly and privately for “BIPOC employees only.”

For those not educated in the left’s alphabet lexicon of races and genders, BIPOC stands for blacks, indigenous people, and people of color. It is designed to create a group of favored minorities while excluding the sexual perverse, which in other contexts the left will gladly celebrate.

What makes the story especially offensive is not this bigoted session and the desire to ban any whites from attending, but the extent in which government officials repeatedly lied about their intentions to discriminate against whites. This story was revealed by Seattle radio host Jason Rantz. Over and over again his office would challenge officials, who would make some absurd claim, and over and over again Rantz would prove this an outright lie, using internal emails obtained by Rantz’s investigation.

For example, one white attendee was specifically removed from the Zoom meeting because of his race.

Cool image time! The photo to the right, cropped and reduced to post here, was created by citizen scientists Kevin Gill and Navaneeth Krishnan from a raw image taken by Juno during its 40th close fly-by of Jupiter in February 2022.

I don’t have a scale, but I would guess that this storm is at least a thousand miles across. The depth is harder to measure, but we looking down into a deep whirlpool for sure.

To bring out the details Gill and Krishnan enhanced the colors significantly. The original is quite bland in comparison, with this storm being the faint dark spot just below the center near the photo’s left edge.

UAE wants to prioritize private enterprise for its space effort

10:17 am

Capitalism in space: According to officials of the United Arab Emirates (UAE) space agency, that nation is working to encourage the growth of a private space industry, funded initially using government money, in its effort to become a major world player in space.

“We’ve spent well over Dh1.5 billion ($408 million) on building capacity within the space industry over the last eight years and we’re more than doubling that over the next decade.”

Laws and regulations, including permits, which would allow interested companies to set up base in the UAE, are already available through a space law passed in 2019.

Companies would also have access to funding from a new initiative launched by the space agency, called Space Analytics and Solutions, which has a budget of Dh20 million. The programme aims to help start-ups build space-based applications that focus on food security, climate change, infrastructure and the oil and gas industry.

The space agency hopes that as these companies progress, they would become less reliant on government funding.

While the UAE’s Al-Amal Mars orbiter was mostly built and launched by foreign companies, it hopes its next major mission, to send an unmanned probe to seven asteroids, will be built almost entirely by companies run by UAE citizens, something they claim they have achieved with an upcoming smallsat Earth observation satellite.

The article also mentioned as an aside that the UAE has ended its 2019 agreement with Virgin Galactic to allow it to launch from the UAE. Instead, it is negotiating with Blue Origin “to set up spaceports.”

More than 4,000 people apply to Japan’s JAXA space agency to become astronauts

10:05 am

In its first new recruitment effort in thirteen years, JASA has received more than 4,000 applications from people eager to become astronauts flying to ISS.

A record number of people applied as the Japan Aerospace Exploration Agency for the first time dropped the requirement that candidates have a university education. The change was made in the hope of recruiting people with a wide range of experience.

However, applicants were required to have at least three years of work experience as of late March, with some academic qualifications being considered as meeting this requirement.

It is unfortunate that the Japanese people do not have more options to get into space. They must either buy a flight from foreign private companies, or depend on a government agency to approve them.

Rogozin proposes Russia launch modules to China’s space station

9:54 am

Dmitry Rogozin, the head of Roscosmos, yesterday proposed in an interview on China’s state-run press that Russia is eager to discuss the possibility of attaching its future space station modules to China’s Tiangong space station.

“As for the Chinese space station, we can discuss construction of some joint modules as well. In order to be friends in space, friendship must first be established back on Earth, and Russia and China are friends on Earth,” Rogozin said. He opined that Russia and China “can be together” in human spaceflights as well.

Whether China will agree is in some ways besides the point. The real question is whether Russia has the capability to do this. Though China and Russia already have a joint agreement to develop a permanent base on the Moon, China is carrying most of the load. Moreover, Russia’s new modules for ISS are decades behind schedule. Whether they will now even be launched to ISS is questionable. Adding these Russian modules to China’s space station will require some major engineering discussions, as neither Tiangong nor the modules were designed for such a thing.

I suspect the two countries will work out an agreement that they will announce with great fanfare. I also expect China will insist that at no time will it be dependent on Russian technology, so that if Russia is delayed or can’t get it done, China will not be hampered in any way. This is essentially their deal for building the lunar base.

Amazon announces launch agreements with Blue Origin, Arianespace, and ULA

9:42 am

Capitalism in space: Amazon today announced major multi-launch agreements with Blue Origin, Arianespace, and ULA to launch its 3,000+ Kuiper satellite constellation.

According to the press release, ULA won 38 launches using its new Vulcan-Centaur rocket (not yet flown), Arianespace won 18 launches using its new Ariane-6 rocket (not yet flown), and Blue Origin won 12 launches using its new New Glenn rocket (not yet flown), with an option for 15 more. The ULA deal is in addition to a previous launch contract of nine launches using the Atlas-5 rocket.

In addition, Amazon hopes to launch two prototype satellites later this year using ABL’s smallsat RS1 rocket (not yet flown).

Overall, this Amazon launch announcement might be the largest launch contract deal ever. However, the company’s reliance on unproven rockets means it will also likely face some delays and failures in its early stages. That the press release makes no mention of any schedule for launches illustrates this fact starkly. All four rockets have already seen major delays. with the three biggest (Vulcan-Centaur, New Glenn, Ariane 6) now more than two years behind schedule, and the likelihood of their first launch occurring in 2022 increasingly unlikely.

SLS dress rehearsal countdown scrubbed an hour before T-0

9:22 am

Yesterday’s first dress rehearsal countdown for NASA’s SLS rocket managed to get within an hour of T-0 with its oxygen tanks half full when mission control scrubbed the countdown.

During chilldown of the lines in preparation for loading the liquid hydrogen, the teams encountered an issue with a panel on the mobile launcher that controls the core stage vent valve. The purpose of the vent valve is to relieve pressure from the core stage during tanking. Given the time to resolve the issue as teams were nearing the end of their shifts, the launch director made the call to stop the test for the day. A crew will investigate the issue at the pad, and the team will review range availability and the time needed to turn systems around before making a determination on the path forward.

No word as yet when they will attempt the next full dress rehearsal. The delays with SLS have so far caused several further delays for Axiom’s private mission to ISS, since NASA has given SLS priority over the range. It has now been pushed back to April 8th.

Note that none of these problems should be a surprise. This is the first time the rocket and mobile launcher have been placed under flight conditions, so minor issues should be expected. At the same time, dealing with these issues now, just before actual launch, rather than earlier in development, illustrates the backwards way NASA’s management has run this program. You can never design anything new perfectly. You need to test and fail and fix along the way. NASA avoids testing because it can’t build anything at a reasonable cost. The result is that when it comes time to launch, lots of previously unidentified minor issues pop up that need fixing.

Astronomers directly image the orbital motion of Jupiter protoplanet 531 light years away

1:41 pm

AB Aurigae B's motion over thirteen years
Click for original image.

Astronomers, using a number of ground- and space-based telescopes, have now directly photographed the orbital motion of a Jupiter protoplanet orbiting a star 531 light years away over a thirteen year time span.

The image to the right, cropped to post here, shows images produced by two Hubble instruments. The caption:

Researchers were able to directly image newly forming exoplanet AB Aurigae b over a 13-year span using Hubble’s Space Telescope Imaging Spectrograph (STIS) and its Near Infrared Camera and Multi-Object Spectrograph (NICMOS). In the top right, Hubble’s NICMOS image captured in 2007 shows AB Aurigae b in a due south position compared to its host star, which is covered by the instrument’s coronagraph. The image captured in 2021 by STIS shows the protoplanet has moved in a counterclockwise motion over time.

From the paper’s abstract:

Using the Subaru Telescope and the Hubble Space Telescope, we find evidence for a Jovian protoplanet around AB Aurigae orbiting at a wide projected separation (~93 au), probably responsible for multiple planet-induced features in the disk. Its emission is reproducible as reprocessed radiation from an embedded protoplanet.

The accretion disk around AB Aurigae happens to lie face on to our line of sight, which facilitates these observations. The data also shows two additional potential proto-planets farther from the star.

Pushback: Musk — offended by Twitter censorship — becomes its biggest shareholder

1:19 pm

Twitter's censorship a target of Elon Musk
Twitter’s censorship a target of Elon Musk

Defeating the censors: On March 25th Elon Musk — opposed to the censorship of conservatives on the social media outlet Twitter — had conducted a poll on Twitter that asked:

Free speech is essential to a functioning democracy. Do you believe Twitter rigorously adheres to this principle?

The poll results were unequivocal: by 70.4% to 29.6% the respondents declared that the present management at Twitter is hostile to free speech.

In the next two days Musk then tweeted “Is a new platform needed?” followed by “Seize the memes of production!” The rumors all suggested that Musk would start his own competing social media platform.

Musk fooled everyone. Instead, as revealed today he proceeded to buy 9.2% of Twitter’s shares, making him the company’s largest individual shareholder.

What Musk will do with this new power is of course not yet known. » Read more

Cool image time! The photo to the right, reduced and annotated to post here, is an oblique view of the terrain near Shackelton Crater and the Moon’s south pole, taken by Lunar Reconnaissance Orbiter (LRO) and released today.

Shackleton-de Gerlache ridge, about 9 miles long, is considered one of the prime landing sites for both a manned Artemis mission as well as the unmanned Nova-C lander from the commercial company Intuitive Machines. To facilitate planning, scientists have created a very detailed geomorphic map [pdf] of this region. As explained at the first link above,

Going back to time-proven traditions of the Apollo missions, geomorphic maps at a very large scale are needed to effectively guide and inform landing site selection, traverse planning, and in-situ landscape interpretation by rovers and astronauts. We assembled a geomorphic map covering a candidate landing site on the Shackleton-de Gerlache-ridge and the adjacent rim of Shackleton crater. The map was derived from one meter per pixel NAC image mosaics and five meters per pixel digital elevation models (DEM) from Lunar Orbiter Laser Altimeter (LOLA) ranging measurements.

Such geology maps guide planning and exploration, but actual images tell us what the first explorers will see. Below is a close-up overhead view of small area at the intersection of the ridge and the rim of Shackleton.

Upcoming Event: The impact of the Ukraine War on the global space industry

9:23 am

LAST CALL: If you wish to watch this event via Zoom or in person you need to comment below. I will then email you the log in information or the location details in Tucson of the event.

Original post:
——————————
On the evening of Tuesday, April 5, 2022, I will be one of three panelists discussing the overall global impact of the Ukraine War on the world’s space industry at another Arizona Space Business Roundtable event in Tucson.

The panelists will be, in speaking order:

Robert Zimmerman: The impact on Russia and the Ukraine space industries
Alex Rodriguez: The impact on the world’s space-related defense and military industries
Stephen Fleming [moderator]: The impact on the rest of the world’s commercial space industries

My readers know who I am.

Alex Rodriguez has worked for Vector and now with Freefall 5G. In the late 1990s, as an Action Officer inside the Pentagon’s J-5 Directorate for Strategic Plans and Policy of the Joint Chiefs of Staff, Alex worked directly on the first round of NATO enlargement in both the Executive Branch and as subsequent detailee on the U.S. Senate Foreign Relations Committee that authorized the ratification of NATO enlargement.

Stephen Fleming, who founded the Arizona Space Business Roundtable, made seed or early-stage investments in over a dozen aerospace companies, including XCOR Aerospace, ICON Aircraft, Nanoracks, RBC Signals, Vector, Freefall, and Phantom Launch. He was also one of the founding investors in the Space Angels Network.

After we each describe the ramifications of the war in these three areas, the room will be opened to Q&A from the audience.

The event will begin at 5:20 pm (Pacific), and likely last until 6:30 pm, though if the discussion is lively we will certainly go on longer.

This is a public event in Tucson, being held jointly by the Arizona Space Business Roundtable and the Arizona Technology Council. It will also be broadcast online.

If you want to attend via Zoom, you will need to express your interest as a comment below, and I will then email you the Zoom url and password. We are not publishing this information publicly to avoid a hacking during the event.

If you wish to come in person please comment below as well and I will then forward you the location. The event is open to the public but I wish to do it this way so that the organizers will have a reasonably accurate estimate of the number of attendees, for planning purposes.

Note that I have written these essays previously about other Arizona Space Business Roundtable events:

NASA aborts fueling in SLS dress rehearsal countdown

9:05 am

UPDATE: Dress rehearsal countdown to resume, now aiming for a 2:40 pm (Eastern) T-0 tomorrow, April 4th.

NASA announced this morning that it has aborted fueling in SLS dress rehearsal countdown because of a problem with the rocket’s mobile launcher.

Teams have decided to scrub tanking operations for the wet dress rehearsal due to loss of ability to pressurize the mobile launcher. The fans are needed to provide positive pressure to the enclosed areas within the mobile launcher and keep out hazardous gases. Technicians are unable to safely proceed with loading the propellants into the rocket’s core stage and interim cryogenic propulsion stage without this capability.

It appears engineers are assessing the issue and hope to resume the countdown so as to proceed with rocket fueling tomorrow.

Rogozin tweets: ISS cooperation to end

5:59 pm

Dmitry Rogozin, the head of Russia’s aerospace corporation, Roscosmos, today confirmed in a series of tweets that Russia intends to end its partnership at ISS due to the sanctions imposed on Russia due to its invasion of the Ukraine.

Rogozin however did not provide any details other than saying:

Specific proposals of Roscosmos on the timing of the completion of cooperation within the framework of the ISS with the space agencies of the United States, Canada, the European Union, and Japan will be reported to the leadership of our country in the near future.

I predict the following:

1. No more barter flights, exchanging Russian and international astronauts on each other’s capsules.
2. No more mutual research on the station.
3. Russia leaves as of ’24, after it adds its remaining modules.

Once those extra modules are launched and installed on the Russian half of ISS, Roscosmos will be more capable of separating its half from ISS and fly it independently. There will be engineering challenges, but this plan will give them two years to address them. It will also give everyone else the time necessary to plan for that separation.

SLS dress rehearsal begins, with press coverage limited by NASA

5:56 pm

NASA today began the two-day-long “wet dress rehearsal” countdown of its first SLS rocket, with T-0 expected to occur at 2:40 pm (Eastern) on April 3rd.

The article at the link provides all the information you could want about this rocket, which is now about seven years behind schedule and having a cost so far about $25 billion. This quote however tells us much about the mentality at NASA:

But much of the test will happen without independent press coverage. NASA plans to provide sanctioned updates on the two-day dress rehearsal via the agency’s website and social media accounts, but news media representatives are not being permitted to listen to the countdown activities.

NASA has cited security and export control restrictions for the move. Numerous media representatives requested access to the SLS countdown audio for the wet dress rehearsal. Launch countdown audio feeds for other U.S. rockets, including those developed by private companies and hauling sensitive U.S. military satellites into orbit, are widely available to the news media and the public.

…NASA plans to release only text updates through the weekend. NASA TV will not be airing any live commentary for the final hours of the practice countdown. The agency’s television channel has previously provided live coverage of similar events, such as space shuttle tanking tests. [emphasis mine]

NASA reasons for not allowing anyone to listen to its audio feed — “security and export control restrictions” — is an utter lie. The real reason is that NASA fears the public’s reaction should anything not go exactly as planned. By blocking access to the audio feed, they can hide any faux pas.

NASA’s fear of course is misplaced. This is a test. No one will be surprised or outraged if it doesn’t go perfectly. Better to be open and up front than try to hide problems, because eventually those problems will be revealed and the cover-up will do far more harm to NASA’s reputation than the problems themselves.

The many new private rocket companies, SpaceX, Rocket Lab, Astra, Virgin Orbit, understand this, which is why they all make their primary countdown audio feeds available, though of course they almost certainly have secondary private feeds where engineers can speak more freely. Similarly, NASA did the same in the 1960s, and then during the entire shuttle program.

Now however “export control restrictions” and “security” requires them to be secretive? It is to laugh.

Sunspot update: Sunspot activity continues to outpace predictions

3:23 pm

It is the first of the month, and NOAA has once again updated its monthly graph showing the long term trends in the Sun’s sunspot activity. As I do every month, I post it below, annotated with additional data to provide some context.

In March the Sun continued its unexpected high activity since the end of the solar minimum in 2020. The number of sunspots once again rose steeply, while also exceeding the predicted count for the month. The actual sunspot count for March was 78.5, not 34.1 as predicted. The last time the count was that high for any month was September 2015, when the Sun was just beginning its ramp down from solar maximum.

Strange terrain at the Martian equator

Strange terrain at the Martian equator
Click for full image.

Cool image time! The photo to the right, cropped to post here, was taken on January 29, 2022 by the high resolution camera of Mars Reconnaissance Orbiter (MRO). It shows a small portion of the floor of 41-mile-wide Tuskegee Crater, sitting at the Martian equator on the rim of the outlet to the giant canyon Valles Marineris.

I have purposely focused on a section of the color strip, because of its strange green color. Most MRO images are reddish (indicating dust) or blue (indicating coarse rocks or ice). Green seems to me to be rare, and in fact is not even mentioned in the MRO science’s team explanation [pdf] of the colors the instrument produces. Since green is neither dust nor ice, this suggests some form of hard bedrock, with a mineralogy that produces that color.

The overview map below gives some context.

Today’s blacklisted American: Biden’s Labor Board attempts to silence conservative news outlet for making bad Twitter joke

11:50 am

Ben Domenech and The Federalist, blacklisted
Ben Domenech and The Federalist, censored by the federal government’s
National Labor Relations Board

Blacklists are back and the Democrats have got ’em: The National Labor Relations Board (NLRB) is attempting to silence the conservative news site The Federalist for “unfair labor practice” because its publisher Ben Domenech sent out a bad Twitter joke in 2019 about unions, and two lawyers who had nothing to do with the company complained to the NLRB.

The National Labor Relations Board (NLRB) has ordered Ben Domenech—publisher of the conservative website The Federalist…—to take down a June 2019 tweet in which he joked about sending employees who wanted to unionize to work in “the salt mines.” Domenech has refused, and the case is now making its way through the courts.

Domenech’s tweet came in response to news that employees of Vox Media Inc. walked off the job in support of unionization. No one at The Federalist had publicly expressed any interest in unionizing, and two of the website’s six employees filed affidavits attesting that they viewed the tweet as a joke. As far as I know, Domenech doesn’t own any salt mines.

The complainants, leftist lawyers Matt Bruenig (a former NLRB attorney) and Joel Fleming, have never worked for or been personally harmed by the Federalist and were clearly acting to silence their political opponents by taking advantage of NLRB’s overly broad regulations, which allow total strangers to file complaints against businesses they don’t like. The NLRB then moves to harass those businesses.

Will XCOR’s Lynx’s spaceplane be reborn as smallsat launcher taking off from California airport?

9:26 am

Capitalism in space: Wagner Star Industries, a startup that now owns the unfinished Lynx spaceplane that bankrupt XCOR had intended for suborbital tourists flights, has signed a agreement with Paso Robles Municipal Airport in California to launch from there.

Wagner’s plan is to reconfigure Lynx as an unmanned first stage that would launch smallsats into orbit. It would launch and land on a runway from Paso Robles.

Wagner Star is in the process of converting the first Lynx vehicle into a drone so it can begin tests, according to the company’s website. The work involves removing life-support systems that had been installed to support the pilot and passenger and installing equipment for remote controlled operation.

Quetzalcóatl would take off from a runway, release its payload in suborbital space, and then glide back to where it took off. The company said it would be able to launch satellites from any commercial airport runway for $5 million per flight. A suborbital flight without a satellite launch would cost $3 million.

A clever plan. I have doubts about the satellite launches, but using this plane to place drones into high altitude where they could then continue to fly for great distances will almost certainly appeal to the military.
