The soft icy Martian northern lowland plains

The soft icy Martian northern lowland plains
Click for full image.

In a cool image post last week, I noted that the near surface “ice sheets in the northern lowland plains are never … smooth, even if well protected.” The picture to the right, cropped, reduced, and sharpened to post here, provides an excellent example. It was taken on November 2, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

It is winter, and the sunlight is coming from the southwest, only 27 degrees above the horizon. The mound on the left is soft, while the depression on the upper right appears to have sand dune ripples sitting on top of a flat glacial mound. This depression may be an eroded crater (no upraised rim) or it could be a sink caused by the sublimation of the near surface ice.

Everywhere else the flat plains are stippled with small knobs.

The overview map below provides more context.

Largest volcanic eruption in years detected on Io

9:49 am

Using instruments on a ground-based telescope, one scientist based at the Planetary Science Institute (PSI) in Arizona has detected the largest volcanic eruption in years on the Jupiter moon Io.

PSI Senior Scientist [Jeff] Morgenthaler has been using IoIO, located near Benson, Arizona to monitor volcanic activity on Io, since 2017. The observations show some sort of outburst nearly every year, but the largest yet was seen in the fall of 2022. Io is the innermost of Jupiter’s four large moons and is the most volcanic body in the Solar System thanks to the tidal stresses it feels from Jupiter and two of its other large satellites, Europa and Ganymede.

IoIO uses a coronagraphic technique which dims the light coming from Jupiter to enable imaging of faint gases near the very bright planet. A brightening of two of these gases, sodium and ionized sulfur, began between July and September 2022 and lasted until December 2022. The ionized sulfur, which forms a donut-like structure that encircles Jupiter and is called the Io plasma torus, was curiously not nearly as bright in this outburst as previously seen. “This could be telling us something about the composition of the volcanic activity that produced the outburst or it could be telling us that the torus is more efficient at ridding itself of material when more material is thrown into it,” Morgenthaler said.

The material released by this eruption could impact Juno during future close approaches of Jupiter.

SpaceX raises another $750 million in private investment capital

9:36 am

SpaceX has just completed another round of fund-raising, gaining another $750 million in private investment capital.

This additional money now means that SpaceX has raised about $10 billion in private money, most of which is being used for the development of Starship and Superheavy. When we add the $4 billion SpaceX will get from NASA for Starship, the company now has $14 billion to build this new rocket.

John Williams – The Cowboys Overture

6:01 pm

An evening pause: It is more than a decade since I last posted this magnificent piece of music from the 1972 John Wayne film, The Cowboys. Time to post it again, because I think it makes a great start to a new year. Rather than John Williams conducting, this time we have a 2018 performance by the Stanisław Moniuszko School of Music Orchestra in Bielsko Biała, Poland, Andrzej Kucybała, conductor.

On the radio plus under the weather

1:12 pm

Two things:

1. I will be on the Space Show with David Livingston tomorrow night for about two hours, beginning at 7 pm (Pacific). You can listen to it here. Please consider calling in. Conversations and questions are always fun.

2. I am a bit under the weather today, so it is likely I will not have the energy to do a blacklist column today or a cool image. This could change, as I get restless if not active. Regardless, I want to take some pressure off by making it voluntary, not a requirement for the day.

Rocketry went BOOM! in 2022, but in a good way

12:44 pm

In my 2021 annual report on the global launch industry, I noted that while 2021 was a banner year for the global launch industry:

Not all is sweetness and light of course. Competition and freedom always includes risk. Some of these new companies will certainly fail. The demand for launch services might not be enough to sustain them all. And factors outside the control of anyone, such as war and further panics like the Wuhan panic, could shut them all down.

In 2022 the launch industry not only topped 2021, setting a new record for successful launches in a single year, the industry was reshaped and changed by the very factors I warned about one year ago. The Russian invasion of the Ukraine resulted in Russia losing its one remaining satellite customer from the west, OneWeb, while the challenges of rocketry caused one already successful launch company, Astra, to suspend its launch services in order to develop a more competitive rocket.

Nonetheless, 2022 remained the most successful year ever in rocketry, smashing the record for successful launches in a single year, set the previous year, by more than 33%. The graph below illustrates well the unprecedented success of 2022.

Hakuto-R successfully completes second mid-course correction

9:36 am

Lunar map showing Hakuto-R's landing spot
Hakuto-R’s planned landing site is in Atlas Crater.

According to Ispace, the private lunar lander company based in Japan, its Hakuto-R lander has now successfully completed second mid-course correction, and is functioning as expected on its way to the Moon.

The maneuver was carried out shortly after midnight on Jan. 2, 2023 (Japan Standard Time) and operations were managed from ispace’s mission control center located in Nihonbashi, Tokyo. This orbital control maneuver is the second maneuver to occur while the lander has been traveling to the moon. The first orbital control maneuver was completed on December 15, 2022. The second maneuver was carried out at a greater distance from Earth and lasted for a longer period than the first maneuver, verifying the company’s capability to carry out orbital maneuvers under various conditions.

As of Jan. 2, 2023, the lander has traveled approximately 1.24 million kilometers from the Earth and is scheduled to be at its farthest point of approximately 1.4 million km from the Earth by Jan. 20, 2023. Once the lander reaches its farthest point from Earth, a third orbital control maneuver may be performed, depending on its navigational status.

While Hakuto-R carries a number of commercial payloads — including Rashid, the first lunar rover built by the United Arab Emirates (UAE) — its primary goal is engineering. Ispace is using this mission to demonstrate its ability as a company to do this, in anticipation of later commercial planetary missions.

Sunspot update: The most sunspots since 2014

9:26 am

Time for my monthly sunspot update, based on NOAA’s monthly graph that tracks the number of sunspots on the Sun’s Earth-facing hemisphere. The newest graph, with December’s numbers added to the timeline, is below. As always, I have added some additional details to provide context.

In December the half-year pause in the ramp up to solar maximum ceased, with the Sun seeing the most sunspots since September 2014. This high activity far exceeded the predicted sunspot count for December 2023, almost doubling it. In fact, December’s sunspot count almost equaled the predicted peak for the upcoming solar maximum, which is not supposed to happen until sometime in 2025.

An afterthought at Southern Utah University
An afterthought at Southern Utah University

Bring a gun to a knife fight: After receiving a threat of legal action [pdf] for violating the first amendment rights of its students, South Utah University (SUU) eliminated a “bias reporting” option on its website that allowed any student to anonymously squelch dissent, simply because he or she did not like what the other person said.

Southern Utah University (SUU) removed a tab from its campus safety website where students and officials could report alleged “bias” or “hate” incidents after the Southeastern Legal Foundation (SLF), a non-profit legal group, challenged that it violates students’ rights to free speech, SLF confirmed to the Daily Caller News Foundation.

A spray of Martian hollows

A spray of Martian sinks
Click for full image.

Cool image time! The photo to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 12. 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Dubbed simply as a a “terrain sample” by the science team, the picture was not taken as part of any specific research project, but instead to fill a gap in the orbiter’s shooting schedule so as to maintain the camera’s proper temperature. When MRO’s science team does this, they try to pick something in the area below that might be interesting. Sometimes they succeed, but often the features in the picture are nondescript.

The white line delineates the rim of a faint and very eroded small crater. Are the depressions that are mostly concentrated just to its south and east sinks or past impact craters? I haven’t the faintest idea. The overview map below helps to answer this question, but only partly.

Philippines issues warning about Chinese rocket debris from launch

9:17 am

Flight path of Long March 3B
Click for full resolution image.

UPDATE: A tweet from China shows that the strap-on boosters of this rocket crashed near homes in China, though no one was hurt.

Original post:
—————–
The Philippine government issued a statement yesterday warning the public about possible debris from the December 29th launch by China of its Long March 3B rocket.

The Philippine Space Agency (PhilSA) is recommending precautionary measures related to expected unburned debris from the Long March 3B rocket scheduled for launch today between 12:33 PM and 01:10 PM Philippine time from the Xichang Satellite Launch Center in Xichang, Sichuan Province, China. Upon confirmation of planned launch dates, PhilSA immediately issued an advisory to all relevant government agencies on the estimated drop zone area and proposed the issuance of appropriate warnings on air and marine access.

Based on the Notice to Airmen (NOTAM) issued by the Civil Aviation Administration of China (CAAC) to the Civil Aviation Authority of the Philippines (CAAP), expected unburned debris, such as the rocket boosters and payload fairing, is projected to fall within a drop zone area located within the vicinity of Recto bank, approximately 137 kilometers from Ayungin Shoal and 200 kilometers from Quezon, Palawan. The unburned debris is designed to be discarded as the rocket enters outer space. While not projected to fall on land features or inhabited areas within the Philippine territory, falling debris poses danger and potential risk to ships, aircraft, fishing boats, and other vessels that will pass through the drop zone.

Though the drop zone avoided inhabited areas, it included regions where fisherman worked, and the flight path still flew over inhabited areas. The risk was extremely low, but it appears China also made no effort prior to launch to coordinate this situation with other governments, such as the Philippines. Its warning apparently arrived just before launch. Thus, there was risk that Filipino fisherman were in the drop zone at launch.

South Korea test flies a solid-fueled missile

9:00 am

South Korea has successfully completed the second test flight of a solid-fueled missile.

The test came after North Korea claimed earlier this month to have staged a test of a “high-thrust, solid-fuel” rocket motor to develop a “new-type” strategic weapon system.

…In March, the state-run Agency for Defense Development carried out the first test of an indigenous solid-fuel space rocket at a testing site in Taean, 150 kilometers southwest of Seoul, to confirm its capabilities.

The rocket is designed to put a small satellite into a low Earth orbit for surveillance operations. Compared with liquid-fuel space vehicles, solid-fuel ones are known to be usually simpler and more cost-effective to launch.

South Korea might claim this rocket is intended for launching smallsats, but its main purpose almost certainly is as a military missile to counter the missile program of North Korea that has accelerated since Joe Biden became president.

SpaceX successfully launches Israeli imaging satellite

12:53 am

SpaceX today successfully launched an Israeli Earth-observation satellite, using its Falcon 9 rocket.

The first stage successfully completed its eleventh flight, touching down softly at SpaceX’s facility at Vandenberg Space Force Base.

This launch completes SpaceX’s 2022 launch year, with a record 61 launches, one more than predicted by the company earlier in the year, and the most ever by a privately owned company.

The leaders in the 2022 launch race:

62 China
61 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 85 to 62, while trailing the rest of the entire world combined 94 to 85. The 85 launches for the U.S. is a new record for a single year, smashing the record of 70 launches set in 1966.

On Monday I will publish my annual full roundup of the state of global launch industry, based on the 2022 numbers.

Pushback: Catholics sue Michigan for imposing queers and the queer agenda in religious schools

12:16 pm

Repealed in Michigan
Doesn’t exist any longer in Michigan

Bring a gun to a knife fight: A century-old Catholic parish based in Grand Rapids, the Sacred Heart of Jesus Parish, is suing Michigan preemptively, anticipating that the state will soon require it to hire queers as well as teach the queer agenda in its school, based on the state’s very broad Civil Rights Act that forbids any discrimination based on sex.

The Michigan Supreme Court recently reinterpreted the prohibition on sex discrimination in Michigan’s Civil Rights Act and penal code to include sexual orientation and gender identity. That change requires Sacred Heart of Jesus Parish and its school, Sacred Heart Academy, to hire faculty and staff who lead lives in direct opposition to the Catholic faith, speak messages that violate Church doctrine, and refrain from articulating Catholic beliefs in teaching its students and when advertising the school to prospective students or job applicants.

Additionally, by preventing Sacred Heart from operating its school consistent with its beliefs, state officials are violating the rights of parents—including the three families who have joined the lawsuit—who specifically chose to send their children to Sacred Heart Academy because the school aligns with their values and religious beliefs.

You can read the lawsuit here [pdf]. It notes in detail the hostility to the Catholic Church by the Attorney General of Michigan, Democrat Dana Nessel, who appears eager to use the law to deny all Catholics their first amendment rights.

A hint at Mars’ past climate cycles

11:16 am

Terraced glaciers in Martian crater
Click for full image.

Cool image time! The photo to the right, cropped to post here, was taken on October 28, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as a “layered feature” inside a small 4,500-foot-wide crater.

Located at 36 degrees north latitude, we are likely looking at glacial ice layers inside this crater, with each layer probably marking a different Martian climate cycle. The terraces suggest that during each growth cycle the glaciers grew less, meaning that less snow fell with each subsequent cycle. This in turn suggests a total loss of global water over time on Mars.

The overview map below gives us the wider context.

China to build giant ground-based optical telescope

9:45 am

China has announced its plan to build ground-based multi-segmented optical telescope, similar in design to the 10-meter Keck Telescope in Hawaii.

Peking University wants to build the largest optical telescope in Asia and close the gap in astronomy capabilities with the rest of the world.

The project aims to create an initial telescope with an aperture of 19.7 feet (6 meters) by 2024; the mirror will be expanded to 26.2 feet (8 m) by 2030. The project, which in English is called the Expanding Aperture Segmented Telescope (EAST), is being led by Peking University.

Like Keck, the primary mirror would be made of smaller segments, fitted together to create the larger mirror. While not as large as Keck, EAST would be among the largest in the world.

Royal Astronomical Society ends blacklisting of James Webb

9:30 am

That’s nice of them: The Royal Astronomical Society in Britain last week announced that it has ended its blacklisting of James Webb, the man who headed NASA during the 1960s space race, by once again permitting writers of science papers for its Monthly Notices journal to use the full name of the James Webb Space Telescope.

The Royal Astronomical Society (RAS) previously criticized NASA for not immediately addressing concerns that Webb persecuted queer employees; the NASA-led James Webb Space Telescope (JWST or Webb) that launched in December 2021 is named after him. But with new information to hand suggesting Webb played no direct role in these issues, Webb’s name can now reappear in scientific papers, the RAS stated Dec. 22.

“The RAS will now allow authors submitting scientific papers to its journals to use either ‘James Webb Space Telescope’ or the acronym ‘JWST’ to refer to the observatory,” RAS officials wrote. The major journals of the RAS include the Monthly Notices of the Royal Astronomical Society (MNRAS), one of the top astronomical journals worldwide.

The society backed off from its position after NASA published a long detailed report documenting the utter falsehood of the claim. Too bad this so-called science organization didn’t consider the evidence itself before issuing its blacklist order. One would think scientists above all would consider evidence, not undocumented slanders, as essential before condemning a person.

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.

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.

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.
