China’s Long March 3B rocket launches “experimental satellite”

9:20 am

China today successfully used its Long March 3B rocket to launch from an interior spaceport what its state-run press labeled an “experimental satellite.”

No word on where the rocket’s strap-on side boosters or first stage crashed within China.

The leaders in the 2022 launch race:

62 China
60 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 84 to 62 in the national rankings, but trails the entire world combined 94 to 84.

This launch cements for China the top spot in launches over SpaceX, since SpaceX only has one more launch planned in 2022, scheduled for just before midnight tonight.

Lex Fridman – Playing Guitar in a Self-Driving Car

6:01 pm

An evening pause: The guitar playing is great, but if this is supposed to be a demonstration of the abilities of self-driving cars, to me it is a utter failure. The drive was on a test track, with no other cars. The car itself was probably never going faster than 25 miles per hour.

In fact, if anything this proves the impracticality of self-driving cars. Such technology might work in a completely controlled environment, but as soon as you add any random human element, it can’t work. Thus our options: we continue to drive ourselves, or we give up our freedom to drive so that all vehicles can be autonomous.

But as I say, the guitar playing is great.

"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

A “What the heck?” glacier image on Mars

5:36 pm

Glacial material on Mars
Click for full image.

Sometimes a cool image goes from bafflement to obvious as you zoom into it. The cool image to the right, cropped to post here, does the opposite. It was taken on October 11, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). I have purposely cropped it at full resolution, so that its eroded glacier nature is most obvious.

The cracks and hollows are likely caused by the sublimation of the near surface underground ice, breaking upward so that the protective surface layer of debris and dust collapses at some points, and cracks at others.

The overview map below further confirms the likelihood that we are looking at glacial features, but when we also zoom out from this close-up we discover things are not so easily explained.

  • NASA’s contract to Collins for space station spacesuit was sole source

    • This story seems to be trying to make a tempest in a teapot. NASA awarded two contracts to two different companies, one to Collins for station suits and a second to Axiom for lunar suits. In the end, both will be competing against each other, as both will clearly work to adapt their suits for other uses.

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.

Today’s blacklisted American: Computer maker Raspberry Pi boycotted because it hired a former policeman

2:02 pm

Toby Roberts: Targeted for blacklisting
Toby Roberts: blacklisted because he once was
a policeman

They’re coming for you next: The mini-computer maker Raspberry Pi has found itself being boycotted because it hired a former policeman.

Toby Roberts, the former policeman, had spent years using Raspberry Pi’s in his policework building covert surveillance devices. As he wrote about his new job, “While I enjoyed my time in the police, it was tough at times, so it’s really pleasant now to be in such a joyful environment.”

The Buzzfeed article at the first link above quotes a small handful of people outraged at this hire. These two comments are typical:

Matt Lewis, a Denver-based site reliability engineer, echoed those sentiments. “I am disgusted that [Raspberry Pi’s] official post on Toby Roberts’ hiring promotes his use of their products to surveil individuals without their consent,” he wrote via Twitter DM. “In my eyes, this behavior is completely unethical and the work Toby has done for 15 years is indefensible. I’m also upset that they have chosen to double down on this position against the community outrage.”

Wikipedia consultant Pete Forsyth, who is from Oregon, also had strong words for Raspberry Pi. “I think this event will mark a turning point in the organization’s reputation,” he wrote via Twitter DM. “It’s hard to see how they can recover the trust they seem to have almost willfully dismantled today.”

Using reflected light from Jupiter to photograph Ganymede’s night side

12:15 pm

Ganymede as seen in the reflected light of Jupiter
Click for full image.

During Juno’s June 7, 2021 close fly-by of Ganymede, scientists used its instruments to obtain the first good image of a part of this Jupiter moon. What made the achievement especially amazing was that the area photographed was only lit by the reflected light from Jupiter, the equivalent of its “earthshine.” From the paper’s abstract:

On 7 June 2021, the Juno spacecraft flew within about 1,000 km of the surface of Jupiter’s largest moon, Ganymede. The Mission used their sensitive navigation camera to photograph the moon’s dark side where it was lit only by scattered sunlight from Jupiter. This new imaging approach revealed multiple surface features, including a patchwork of different surface textures (such as grooved terrain), several craters, and ejecta deposits. These features had not been visible in images collected by previous spacecraft.

The picture to the right is from figure 2 of the paper, cropped and reduced to post here. It shows a region on Ganymede that in the earlier images had shown few details because the lighting was poor and thus features were not easily discerned (as can be seen by the inset in the lower right). In the new picture, the only light was reflected from Jupiter, and its low angle brings out the surface topography.

Russian investigators conclude leak on Soyuz caused by external impact

9:20 am

ISS as of November 28, 2022
ISS after November 28, 2022 docking of unmanned Dragon freighter.
MS-22 is the Soyuz capsule that is leaking.

The Russian investigators yesterday concluded that the coolant leak on the Soyuz capsule docked to ISS was caused by an external impact, either by a meteroid or a small piece of space junk.

A decision on whether this capsule is still usable for manned flight will be made sometime in January. If not, Russia will move up the launch of the next Soyuz to ISS one month from March to February, but launch it empty. If so, managers will leave the schedule as is.

If the engineers determine the capsule is not flightworthy, it will mean however that until February, ISS is short one lifeboat. At present there are two Dragon capsules docked to ISS, one manned and one cargo. Both return to Earth with a habitable interior, but the cargo capsule is not intended for manned flight. In an emergency however it might be possible to use it.

This situation suggests that NASA should pay to get SpaceX to upgrade the cargo Dragons so that they could always be used as an emergency lifeboat.

SpaceX launches 54 more Starlink satellites

9:04 am

SpaceX early today completed its 60th successful launch in 2022, putting 54 Starlink satellites into orbit using its Falcon 9 rocket.

This achievement matches a prediction Elon Musk made early in 2022. More significant, except for two years (1965 and 1966), SpaceX completed more launches in 2022 than the United States achieved each year since Sputnik. And it did it not as a nation, but as a private company, for profit.

SpaceX’s achievement this year also allowed the U.S. to smash its own record for annual launches.

The first stage successfully completed its 11th flight, landing on a drone ship in the Atlantic.

The leaders in the 2022 space race:

61 China
60 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 84 to 61 in the national rankings, but trails the entire world combined 93 to 84.

Only one more launch, by SpaceX, is publicly scheduled for 2022.

Today’s blacklisted American: Black scientist blacklisted for doing good research

1:57 pm

Oluseyi Hakeem, blacklisted
Hakeem Oluseyi, Space Science Education Lead
for NASA’s Science Mission Directorate

They’re coming for you next: Today’s blacklist column describes an effort to not only cancel from history the man who led NASA for almost the entire 1960s space race, but to also blackball a scientist for doing good research that proved the campaign was not based on any facts.

Shortly before the launch of the James Webb Space Telescope last year, a petition was instigated to get it renamed because of accusations that Webb had persecuted homosexuals during his term as NASA administrator in the 1960s. As is now typical of our modern bankrupt intellectual class, as soon as this petition was issued more than 1,700 people signed it, all accepting at face value its accusations against Webb without any further research.

One scientist, who happened to be black, took a more detailed look at those accusations however and found them to be spurious. As Hakeem Oluseyi wrote:

Finding Martian glaciers from orbit

11:45 am

Glacier flow on Mars
Click for full image.

Today’s cool image is a great example of the surprises one can find by exploring the archive of the high resolution pictures that Mars Reconnaissance Orbiter (MRO) has produced since it arrived in Mars orbit back in 2006. The picture to the right, rotated, cropped, and reduced to post here, was taken by MRO’s high resolution camera back on May 4, 2017. I only found it because I had picked out a October 24, 2022 high resolution image that covered a different area of this same flow feature just to the north east. In trying to understand that 2022 picture I dug to see other images had been taken around it, and found the earlier 2017 photo that was even more interesting.

Neither however really covered the entire feature, making it difficult to understand its full nature. I therefore searched the archive of MRO’s context camera, which has imaged the entire planet with less resolution but covering a much wider area per picture. The context camera picture below captures the full nature of this feature.

SpaceX has about 100 Starlink terminals working in Iran

8:47 am

Though the Iranian government opposes their use, according to a tweet by Elon Musk SpaceX now has almost 100 Starlink terminals working in Iran.

Elon Musk announced that SpaceX has almost 100 Starlink terminals active in Iran. SpaceX activated Starlink services in Iran in September, supporting the United States’ stance on providing internet freedom and free flow of information to Iranians.

Unlike Ukraine, SpaceX does not have the cooperation of the Iranian government to expand Starlink services in the country. In Ukraine, President Volodymyr Zlenskyy and the Minister of digital transformation Mykhailo Feorov have actively supports Starlink connection during the war with Russia.

In contrast, the Iranian government is actively trying to limit its citizens’ internet access. The United States government has taken a stance against the Iranian government’s decision regarding internet access for its people.

SpaceX has routinely cooperated with foreign governments before selling terminals, likely because to do otherwise would get it in trouble with the U.S. State Department. In this case however the State Department appears to have approved this action, and SpaceX then made it happen.

China launches Earth observation satellite

8:41 am

China today successfully launched a classified Earth observation satellite using its Long March 4B rocket.

As the launch was from an interior spaceport, the rocket’s lower stages landed somewhere in the interior of China.

The leaders in the 2022 launch race:

61 China
59 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 83 to 61 in the national rankings, but trails the entire world combined 93 to 83.

At the moment, the only known remaining launches in 2022 are two SpaceX Falcon 9 launches. However, China routinely launches a lot in the November/December timeframe, so we should not be surprised if they complete one or two launches as well in the next few days.

  • Russian relations with Kazakhstan souring

    • Kazakhstan has “renounced concessions for Russian logistics companies that transport goods for import to Russia,” even as a Russian official threatened Kazakhstan with invasion. For the Russian space program these tensions could be disastrous, as the Baikonur spaceport in Kazakhstan is presently the only place it can launch humans.

Cones, mounds, and layers of Martian ice?

Cones, mounds, and layers of Martian ice?
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on September 10, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The location is at 38 degrees north latitude, in the Martian northern lowland plains. At this latitude in these plains the geological features seen in high resolution pictures almost always invoke near surface ice, including processes that disturb that underground ice layer.

This picture is no different. Not only does it appear that a glacier is flowing down from the top of east-west ridge, the middle mound includes a crater with its southeast rim gone and appears filled with material that suggests ice.

The greater geographic context of this location can be seen in the overview map below.

The increase in violence against churches since 2018

The modern dark age: According to a recently published 84-page report [pdf] by the Family Research Council, vandalism, violence, and arson against churches and religious institutions has nearly tripled since 2018.

From the report:

Family Research Council identified a total of 420 documented acts of hostility that targeted 397
individual churches. These incidents occurred between January 2018 and September 2022 across 45 U.S. states and Washington, D.C. To conduct this research, we analyzed open-source documents, reports, and media outlets to assess the number of acts of hostility against churches over a five-year span.

A long-armed galaxy

8:51 am

Galaxy with long and faint tidal streams
Click for full image.

Cool image time! The photo to the right, cropped, enhanced, and reduced to post here, was taken by the Hubble Space Telescope as part of a survey of peculiar looking galaxies.

The peculiar spiral galaxy ESO 415-19, which lies around 450 million light-years away, stretches lazily across this image from the NASA/ESA Hubble Space Telescope. While the centre of this object resembles a regular spiral galaxy, long streams of stars stretch out from the galactic core like bizarrely elongated spiral arms. These are tidal streams caused by some chance interaction in the galaxy’s past, and give ESO 415-19 a distinctly peculiar appearance.

ESO 415-19’s peculiarity made it a great target for Hubble. This observation comes from an ongoing campaign to explore the Arp Atlas of Peculiar Galaxies, a menagerie of some of the weirdest and most wonderful galaxies that the Universe has to offer. These galaxies range from bizarre lonesome galaxies to spectacularly interacting galaxy pairs, triplets, and even quintets. These space oddities are spread throughout the night sky, which means that Hubble can spare a moment to observe them as it moves between other observational targets.

I have intentionally brightened the galaxy to make the two faint two tidal streams more obvious. That they are so faint compared to the galaxy itself is in itself a mystery.

Today’s blacklisted American: Professor fired by a North Carolina school for having opinions

2:46 pm

David Phillips
Dr. David Phillips

They’re coming for you next: Officials at the North Carolina Governor’s School (“a residential summer program for the state’s most talented rising high-school seniors.”) fired David Phillips, a professor there for eight summers, because they did not like the content of the optional three session seminar he held critiquing critical race theory.

In other words, they decided to blackball him simply because they did not agree with his opinions.

Phillips has now sued, with the Alliance Defending Freedom acting as his legal firm. The preamble of his lawsuit [pdf] describes what happened.

At the conclusion of each lecture, members of the audience — including staff members — reacted with open hostility to the ideas and viewpoints discussed. And they attacked whiteness, maleness, heterosexuality, and Christianity — none of which should have been relevant — in their comments and questions. Despite the hostility, Dr. Phillips stayed long after the published end time for each lecture to respond calmly to each question, and he even offered to meet with students and staff members later for further discussion.

Attack that injured Rogozin in the Ukraine also killed two

12:59 pm

Dmitry Rogozin playing soldier in the Ukraine
Dmitry Rogozin playing make-believe soldier
recently in the Ukraine

More details have now emerged about the explosion that injured former Roscosmos chief Dmitry Rogozin, including the fact that the attack, in Ukrainian occupied territory in Donetsk, also killed two.

The former head of Russia’s space agency was wounded when an artillery shell exploded as he celebrated his birthday in a hotel near the front line in Ukraine. Dmitry Rogozin, a flamboyant Russian politician who was once a deputy prime minister, was reportedly hit in the buttocks, head and back by shrapnel.

Two people were killed in the attack and several others were wounded, authorities in Donetsk said on Thursday, and Mr Rogozin said he was due to be operated on. Russian state news channel Rossiya 24 TV said the former space chief was celebrating his 59th birthday at the Shesh-Besh hotel and restaurant with several other separatist officials.

But Mr Rogozin insisted the incident took place during a “work meeting”.

Russian investigators think the shell came from a French-made Caesar self-propelled howitzer.

The criticism of Rogozin concerning this story has been quite ugly.

“A party 10 kilometres away from the front line with the Ceasar’s range of 40 kilometres? I would reprimand him for being childish,” [wrote Yuri Podolyaka, a prominent pro-Kremlin blogger.] “Two people have died in that restaurant, which, I think, is on his conscience.”

Rogozin’s path has been steadily downward since he was deputy prime minister of Russia’s defense department from 2011 to 2018. First he was demoted to head of Roscosmos, where he ended up losing Russia more than a half billion in income by his cancellation of the launch contract with OneWeb. Worse, that cancellation, and Rogozin’s confiscation of 36 OneWeb satellites, ended any chance of Russia getting any international business for years to come.

These actions caused him to be fired from Roscosmos in July, and shipped to the Ukraine (the modern equivalent of Siberia) to act as an envoy in the Russian-occupied territories. Once there, he did nothing to enhance his reputation. By holding this very public birthday party, at a public place so close to the front lines, was almost guaranteeing he and his party would be attacked.

I wish he quickly recovers from his injuries, but I also think Putin would be foolish to give this guy any further positions of authority.

Crater at the edge of the Martian south pole ice cap

11:20 am

Oblique view of south pole crater
Click for full image.

Overview map

Cool image time! The oblique panorama above, reduced and sharpened to post here, was created from an image taken on May 19, 2022 by the European orbiter Mars Express. Its location on edge of the layered deposits of ice and dust that form most of the Martian southern ice cap is indicated by the white rectangle on the overview map to the right. From the press release:

While it may look like a winter wonderland, it was southern hemisphere spring at the time and ice was starting to retreat. Dark dunes are peeking through the frost and elevated terrain appears ice-free.

Two large impact craters draw the eye, their interiors striped with alternating layers of water-ice and fine sediments. These ‘polar layered deposits’ are also exposed in exquisite detail in the rusty red ridge that connects the two craters.

The scattered white patches are either water frost, or the winter mantle of dry ice, both now sublimating away with the coming of spring.

The black line on the overview map indicates the extent of the layered deposits, and suggest that the ridgeline is not considered part of that ice cap layer, in contradiction to the press release language above.

Which is it? I would guess the answer is simply the uncertainty of science. Some scientists took a look here and decided the ridge was actually a base layer sticking up through the layered deposits. The European scientists who took this picture have instead concluded, based on the image, that the ridge is part of the layer deposits.

Newly passed Senate bill requires consultation between industry and government on space junk

9:50 am

Though the bill still needs to be passed by the House, a just passed Senate bill requires consultation between industry and government on space junk, short circuiting recent attempts at the FCC as well as in the House to impose arbitrary government regulations.

You can read the Senate bill here [pdf].

The final result will still be government regulation on the lifespan and final deposition of any object placed in orbit, from nanosats to large manned space stations, but unlike the earlier FCC proposal and House bill, NASA and other government agencies will have to obtain feedback from the commercial space industry before such regulations are imposed.

Sounds great, eh? In truth, this bill in the end still gives full power to the federal government to control the launching of future spacecraft of all sizes. It also leaves the details entirely up to the bureaucracy. If passed Congress would cede its regulatory power to unelected bureaucrats in the executive branch.

The requirement that industry consultation occur simply means that the initial regulations will likely make some sense. Beyond that however the power it bequeaths to the federal bureaucracy in NASA, FAA, FCC, and other agencies will in the long run be still abused.

The need for the establishment of an independent space-faring society, free from odious Earthbound regulation, continues to grow.

Soyuz hole not caused by a Geminid meteor

9:29 am

According to an analysis by both NASA and Russian engineers, the 0.8 mm hole in the coolant system on the Soyuz docked to ISS was not caused by an object from the Geminid meteor shower that had occurred about the time the leak appeared.

The Soyuz vehicle, known as MS-22, sprayed its coolant into space on Dec. 14, the same day that the annual Geminid meteor shower peaked. But there’s no causal connection, NASA and Russian space officials said. “We did look at the meteor showers that were occurring,” Joel Montalbano, NASA’s International Space Station program manager, said during a press briefing on Thursday (Dec. 22). “Both the trajectory team in Houston and the trajectory team in Moscow confirmed it was not from the meteor showers; it was in the wrong direction.”

The engineers claim the hole could still have been caused by an impact, just not from these meteors.

NASA requesting proposals for raising Hubble’s orbit

9:23 am

NASA has published a request for proposals from the private commercial space industry for a possible future mission to raise Hubble’s orbit.

NASA published a request for information (RFI) Dec. 22 asking industry how they would demonstrate commercial satellite servicing capabilities by raising the orbit of Hubble. The agency said it is looking for technical information about how a company would carry out the mission, the risks involved and the likelihood of success.

NASA emphasized in the RFI that it had no plans to procure a mission to reboost Hubble. “Partner(s) would be expected to participate and undertake this mission on a no-exchange-of-funds basis,” the document stated, with companies responsible for the cost for the mission.

Apparently, this RFI was issued as a direct result of the agreement between NASA and SpaceX to study a Dragon mission to do exactly this, which in turn was prompted by Jared Isaacman, as part of his private Polaris program of manned Dragon/Starship space flights. I suspect that NASA officials realized that not only were their engineering advantages to getting more proposals, there were probably legal and political reasons for opening the discussion up to the entire commercial space community.

Ideally, a Hubble reboost mission should occur by 2025, though the telescope’s orbit will remain stable into the mid-2030s.

Juno experienced data download issue during most recent Jupiter close flyby

9:07 am

Right after Juno made its 47th close fly-by of Jupiter on December 14, 2022, the download of the obtained data was suddenly disrupted, forcing engineers to put Juno into safe mode.

The issue – an inability to directly access the spacecraft memory storing the science data collected during the flyby – was most likely caused by a radiation spike as Juno flew through a radiation-intensive portion of Jupiter’s magnetosphere. Mission controllers at NASA’s Jet Propulsion Laboratory and its mission partners successfully rebooted the computer and, on Dec. 17, put the spacecraft into safe mode, a precautionary status in which only essential systems operate.

As of Dec. 22, steps to recover the flyby data yielded positive results, and the team is now downlinking the science data. There is no indication that the science data through the time of closest approach to Jupiter, or from the spacecraft’s flyby of Jupiter’s moon Io, was adversely affected. The remainder of the science data collected during the flyby is expected to be sent down to Earth over the next week, and the health of the data will be verified at that time. The spacecraft is expected to exit safe mode in about a week’s time. Juno’s next flyby of Jupiter will be on Jan. 22, 2023.

That such disruptions have actually not occurred very often on Juno is somewhat remarkable, considering the hostile nature of the environment around Jupiter.

Perseverance experiment generates new record of breathable oxygen on Mars

8:59 am

MOXIE, an experiment on the rover Perseverance to see if breathable oxygen could be generated from the carbon dioxide in the Martian atmosphere, has set a new production record.

The atmosphere around Jezero Crater, the present location of Perseverance, reached peak density for the year mid (Earth) summer. This presented the perfect opportunity for the MOXIE science team to step on the accelerator and test how fast we could safely produce oxygen. This test occurred on Sol 534 (Aug. 22, 2022) and produced a peak of 10.44 grams per hour of oxygen. This represented a new record for Martian oxygen production! The team was thrilled to surpass our design goal of 6 grams per hour by over 4.4 grams. The peak rate was held for 1 minute of the 70 minutes oxygen was produced during the run.

MOXIE’s next opportunity to operate came recently. Despite the decreasing density of the Mars atmosphere, on Sol 630 (Nov. 28, 2022) MOXIE managed to break the record again and produce nearly 10.56 grams per hour at peak. Oxygen production was sustained for a 9.79 grams per hour for nearly 40 minutes.

These numbers may seem small, but MOXIE production runs are limited by available rover power. In addition, MOXIE technology was miniaturized to accommodate the limited space available on the rover. A MOXIE for a human Mars mission would produce oxygen nearly 200 times faster and work continuously for well over a year.

Ten grams per hour is about half what one person needs to breathe, and is a little less than a large tree produces. Moreover, MOXIE had earlier conducted seven other runs, producing about six grams of oxygen per hour during each.

Based on these tests, MOXIE has unequivocally proven that future human explorers will not need to bring much oxygen with them, and will in fact have essentially an unlimited supply, on hand from the red planet itself. More important, MOXIE has also proven that the technology to obtain this oxygen already exists.

All we need to do is plant enough MOXIE trees on Mars.
