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

The most valuable real estate on the Moon
Click for full image.

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.

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 or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also 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

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.

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.

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.

Rocket Lab launches two BlackSky Earth observation satellites

9:41 am

Capitalism in space: Rocket Lab today successfully launched two commercial BlackSky Earth observation satellites using its Electron rocket.

This was Rocket Lab’s the fourth mission for BlackSky, with each launch putting two satellites in orbit. The satellites provide high resolution imagery to commercial and government customers, imagery presently in high demand because of the Ukraine War.

The leaders in the 2022 launch race:

12 SpaceX
8 China
4 Russia
2 ULA
2 Rocket Lab

The U.S. now leads China 19 to 8 in the national rankings.

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.

Ronnie O’Sullivan’s record break in Snooker

6:01 pm

An evening pause: Hat tip Phill Oltmann, who has tried several times to explain Snooker to me and failed. The game however appears to be a variation of the U.S. pool game hi-low, though maybe more complicated.

The point is that in the video below, O’Sullivan starts the game and proceeds to clear the table, and he does it in less than six minutes, the fastest time ever. It is amazing to watch.

Another week has passed in the Ukraine war, and with it we begin to see increasing evidence that not only has the Russian invasion stalled, but that the Ukraine is beginning to push back with more and more effectiveness.

The two maps to the right are from the Institute for the Study of War (ISW) and have been simplified, annotated, and reduced to post here. The top was from ISW’s March 24, 2022 report, the bottom from its report today. The dark red areas are regions either controlled by Russia or areas of confirmed Russian advance. The light red indicates areas the Russians claim to control without confirmation. The blue areas mark areas retaken by the Ukraine in battle. The circles indicate areas of recent heavy fighting.

The green arrows I have added to both maps indicate areas where there have been changes since the week prior. Like last week, the arrows point almost entirely to areas where Russian control has ebbed, either because the Russians have chosen to retreat, or because Ukrainian forces have pushed them out. The summary from ISW is succinct:

Pushback: University’s blacklisting of a student quickly ends when confronted by lawyers

1:08 pm


Boris Badenov: The school administrators at
Southern Illinois University

Today’s blacklist story came and went so quickly that no one in the press really ever had a chance to cover it. I however want to highlight it today because it tells us a great deal about today’s bankrupt academic culture, and its paper tiger nature if challenged.

On February 10, 2022, Jamie Ball, the director for Equal Opportunity, Access and Title IX Coordination at Southern Illinois University in Edwardsville, sent notices to Maggie DeJong, a student in the school’s Art Therapy Counseling Program, telling DeJong that she was forthwith forbidden to interact in any way with three other students.

Because DeJong attended classes and also worked at the same facility as these three students, the orders essentially blacklisted her from school through the end of the ’22 semester.

Ball provided no facts or reasons for the “no-contact” orders, other than saying that any contact between DeJong and these three students “would not be welcome or appropriate at this time.” Ball’s order also admitted that no harassment or violation of school policy had occurred. Her order was simply “to prevent interactions that could be perceived by either party as unwelcome, retaliatory, intimidating, or harassing.”

In other words, Ball was punishing DeJong for something that might happen, likely based on secret accusations made by those three students.

On February 23rd, less than two weeks later, lawyers from the Alliance Defending Freedom (ADF) sent the school’s Chancellor, Randy Penbrook, a letter [pdf] outlining the illegality of this action, and demanding the no-contact orders be immediately rescinded.

A large Martian river basin with delta

11:44 am

Map of Hypanis Valles river basin on Mars
Click for full image.

Cool map time! The map to the right, reduced to post here, is figure 1 in a new paper outlining the known geology of what appears to be a large ancient and now dry river basin with delta on Mars, found north of Valles Marineris and draining into the northern lowland plain dubbed Chryse Planitia where both Viking-1 and Mars Pathfinder landed, in 1976 and 1997 respectively.

The river basin itself is called Hypanis Valles. The white splotch at the river basin’s outlet is dubbed the Hypanis Deposit, and is thought by some scientists to be a delta of material that was placed there when the river was active 3.6 billion years ago and poured into what some scientists believe was an intermittent ocean in Chryse Planitia. From the paper’s conclusion:

As proposed in prior works, Hypanis may have formed subaqueously as a delta, and may record a water level drop of about 500 m[eters, or about 1,600 feet] as a shoreline retreated to the northeast. We identified kilometer-sized cones and mounds which appear to have erupted onto the surface. Characteristics of these features more closely resemble those of outgassing, sedimentary diapirism, and mud volcanism rather than of igneous volcanism.

The intermittent ocean theory has problems however. For this delta to have formed underwater that ocean would have to have been much much larger than estimated based on the present known data, extending out to cover almost all of Chryse Planitia, in some places to a very great depth.

Some scientists have hypothesized that the ocean need not have been that large because a land dam would have confined it to a smaller region at the river’s outlet. This research however found no evidence of such a dam. However, the paper also noted that “Further work could examine the role of ice or glaciers in the formation of Hypanis and determine if an ice dam would be plausible.”

And of course there remains the more fundamental mystery of liquid water on the Martian surface, which makes the river basin itself a puzzle. No generally accepted model allowing for surface liquid water on Mars presently exists. The possibility that ice and glaciers could have done the job comes to mind again. Though the geology in this region reveals what looks like to our Earth eyes to be a very large river system, now dry, this is not Earth but an alien planet. Tributary systems like this might form from different and as yet not understood processes on Mars, some of which might involve glaciers.

Scientists: On Mars surface elevation doesn’t matter that much in terms of radiation protection

9:41 am

In a paper published in February, scientists determined from models and data that the thickness of Martian cave ceilings required to protect you from radiation is not that much different whether you are on top of Olympus Mons (the Mount Everest of Mars), or at the bottom of Hellas Basin (Mars’ Death Valley).

From the paper’s conclusion:

Overall, the atmospheric thickness is not a dominant parameter for the required shielding. However, at a low-altitude crater where the surface pressure is above 1,000 Pa, the required subsurface shielding is about 10–20 cm [4 to 8 inches] less than at the top of high mountains where the pressure is below 100 Pa. Moreover, solar activities which determine the GCR flux arriving at Mars play an role. To reduce the annual effective dose to be below 100 mSv, the required shielding is 1.5–1.6 m [about 5 feet] during solar minimum and 0.9–1.1 m [a little more than 3 feet] during solar maximum. For a threshold of 50 mSv, the required shielding is 2.1–2.2 m [about 7 feet] during solar minimum and 1.7–1.9 m [about 6 feet] during solar maximum.

Essentially, what this research suggests is that to properly shield any underground facility, you need to cover it with at least seven feet of material, or be in a cave where the ceiling is that thick. It really doesn’t matter how much atmosphere is above you. Even at its thickest at the lowest elevation, Mars’ atmosphere doesn’t provide much protection.

Astronomers think they have detected the most distant star ever

9:24 am

The most distant star ever detected?
Click for full image.

The uncertainty of science: Using the Hubble Space Telescope astronomers now think they have detected the most distant single star ever located, the light of which is estimated to have come from a time only less than a billion years after the Big Bang itself.

The star, nicknamed Earendel by astronomers, emitted its light within the universe’s first billion years. It’s a significant leap beyond Hubble’s previous distance record, in 2018, when it detected a star at around 4 billion years after the big bang. Hubble got a boost by looking through space warped by the mass of the huge galaxy cluster WHL0137-08, an effect called gravitational lensing. Earendel was aligned on or very near a ripple in the fabric of space created by the cluster’s mass, which magnified its light enough to be detected by Hubble.

The arrow in the image, cropped and reduced to post here, points to the theorized star. Note the arc that tiny dot lies along. This arc is the result of the gravitational lensing, and illustrates quite bluntly the large uncertainties of this discovery. We are not seeing the star itself, but the distorted light after it passed through the strong gravitational field of the cluster of galaxies. The scientists conclusion that this dot is thus a single star, must be view with great skepticism.

Nonetheless, the data is intriguing, and will certainly be one of the early targets of the James Webb Space Telescope, which could confirm or disprove this hypothesis.

New Shepard completes another commercial suborbital flight

9:09 am

Capitalism in space: Blue Origin’s New Shepard suborbital spacecraft today successfully completed its fourth manned commercial flight, carrying six passengers to a height of about 70 miles for total flight time of a little less than eight minutes.

I have embedded the live stream below the fold, cued to just before launch. Everything went almost routinely, which is a very good thing for a rocket company.

The most interesting aspect of this flight was that one of the passengers was George Nield, who had:

…previously served as associate administrator for the US Federal Aviation Administration (FAA) Office of Commercial Space Transportation from 2008 to 2018, being responsible for launch licensing and regulation for all commercial launch activities during that time.

During Nield’s term, the government worked very hard to help get launches off the ground, which laid the groundwork for the success of both SpaceX’s orbital Falcon 9 and Falcon Heavy rockets, as well as the suborbital spacecraft of Blue Origin and Virgin Galactic. His effort also helped jumpstart the new smallsat rocket industry.

Since his retirement, the FAA’s attitude toward regulation has become more oppressive, especially since the beginning of the Biden administration in 2021.

Another update on the lie that was COVID

12:16 pm

How governments determined policy against COVID
How our governments continue to determine policy against COVID

One week ago I published a short essay listing a number of news stories that, as I wrote then, “illustrate starkly the foolishness and the over-reaction to COVID.”

It appears I might have to make this a weekly feature. In the last seven days I’ve collected a whole bunch of new articles, all of which provide further evidence of the lie that was COVID. Not only did our political and health leadership in government routinely lie to us, they often exhibited a remarkable ignorance about some basic science. Until there is reckoning that cleans house in these government agencies, Americans should never believe anything they say.

Most of the stories this past week document the overall failure of the COVID shots to do what these government officials promised: to prevent infection. To understand the significance of this fact, one must go back and review the claims made by government health officials when these shots were first developed. From the beginning these officials repeatedly claimed that the shots would prevent transmission of the virus, and protect people from any Wuhan flu infection if they got the jab. Just watch some of the videos here. Over and over again so-called experts claimed back in the spring of 2021 that the shots would “prevent transmission.”

Active volcanoes on Pluto?

9:16 am

Elevation map of Wright Mons on Pluto
Elevation map of Wright Mons on Pluto

The uncertainty of science: According to new research published yesterday, scientists now posit that there might be recent volcanic activity on Pluto, based on data and images sent back by New Horizons during its fly-by of the planet in 2015.

You can read the paper here. From its abstract:

The New Horizons spacecraft returned images and compositional data showing that terrains on Pluto span a variety of ages, ranging from relatively ancient, heavily cratered areas to very young surfaces with few-to-no impact craters. One of the regions with very few impact craters is dominated by enormous rises with hummocky flanks. Similar features do not exist anywhere else in the imaged solar system. Here we analyze the geomorphology and composition of the features and conclude this region was resurfaced by cryovolcanic processes, of a type and scale so far unique to Pluto. Creation of this terrain requires multiple eruption sites and a large volume of material (>104 km3) to form what we propose are multiple, several-km-high domes, some of which merge to form more complex planforms. The existence of these massive features suggests Pluto’s interior structure and evolution allows for either enhanced retention of heat or more heat overall than was anticipated before New Horizons, which permitted mobilization of water-ice-rich materials late in Pluto’s history. [emphasis mine]

The image to above is Figure 10 in the paper’s supplementary material [pdf]. It shows the volcano-like appearance of Wright Mons on Pluto, a mound approximately 3,000 feet high with a central depression equally deep, with a volume “similar in magnitude to that of the Hawaiian volcano Mauna Loa.”

These conclusions are quite tantalizing, but the amount of data is sparse, and thus it is wise not to take them too seriously. For example, the scientists have no idea how Pluto could presently have any form of liquid or active volcanism. Another mission to Pluto — studying it over a long time from orbit — will be required to determine how active the planet really is, or if it is active at all.

Europe’s deep space communications network to support India’s next two missions beyond Earth orbit

8:52 am

The new colonial movement: Based upon a 2021 agreement, the European Space Agency (ESA) today outlined how its deep space communications network of antennas will support India’s next two missions beyond Earth orbit.

ESA’s global deep-space communication antennas will provide essential support to both missions every step of the way, tracking the spacecraft, pinpointing their locations at crucial stages, transmitting commands and receiving ‘telemetry’ and valuable science data.

In June 2021, ESA and the Indian Space Research Organisation (ISRO) signed an agreement to provide technical support to each other, including tracking and communication services to upcoming Indian space missions via ESA’s ground stations.

The first missions to benefit from this new support agreement will enable India look to the Sun and the Moon with the Aditya-L1 solar observatory and Chandrayaan-3 lunar lander and rover, both due to launch in 2022 from the Satish Dhawan Space Centre in Sriharikota Range (SDSC SHAR), India.

Though scheduled for launch this year, ISRO (India’s space agency) has not yet announced firm launch dates for either.

This arrangement signals an effort by India and Europe to remain independent of the American Artemis program, which is NASA’s central program for manned missions beyond Earth orbit. To partner with NASA for such missions the Trump administration had demanded nations sign the Artemis Accords, though that requirement might have been eased by the Biden administration for deep space communications.

Regardless, this agreement gives both India and ESA flexibility for remaining outside the accords, at least for now. Neither India nor most of the partners in the ESA have signed, with France and Germany the most notable European nations remaining outside the accords.

Soyuz capsule returns three astronauts safely, completing Mark Vande Hei’s 355 day mission

8:28 am

A Russian Soyuz capsule successfully returned three astronauts back to Earth today, thus completing Mark Vande Hei’s 355 day mission, the longest so far achieved by an American astronaut.

Vande Hei’s record is the fifth longest overall, behind four other Russians on Mir. Musa Manarov and Vladimir Titov were the first to complete a year-long flight in 1987-1988. Sergei Avdeyev’s flight of 381 days on Mir in 1998-1999 is the second longest. Valery Polyakov holds the record for the longest flight, 437 days in 1994-1995.

Now that Vande Hei is safely back on Earth, expect Dmitry Rogozin, the head of Roscosmos, to make some announcement in the next day or so further limiting cooperation at ISS. It is my expectation he will end the discussions between Roscosmos and NASA to exchange one-for-one flights on each other’s capsules. While the partnership to maintain and occupy ISS will continue, Rogozin will likely end any cooperation otherwise.

China today successfully launched what appear to be three technology test satellites using its Long March 11 rocket.

The three satellites Tianping-2A, Tianping-2B and Tianping-2C will provide services such as atmospheric space environment survey and orbital prediction model correction.

This is all we know about these satellites.

The leaders in the 2022 launch race:

11 SpaceX
8 China
4 Russia
2 ULA

The U.S. still leads China 17 to 8 in the national rankings.
