Cool image time! The photo to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 18, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It includes a wide variety of geology related to sublimating ice, including expansion cracks as well as several different examples of what scientists call “expanded craters,” impacts that occurred in near surface ice and have been reshaped by the ice’s melting and sublimation at impact and then later. It also shows some obvious glacial fill in the two distorted craters at the center right.

A 2017 dissertation [pdf] by Donna Viola of the University of Arizona outlines nicely what we know of Martian expanded craters. As she notes in her conclusion:

Webb and Keck telescopes track clouds on Titan

Clouds on Titan
Click for original image.

Astronomers have used the Webb Space Telescope and the Keck Observatory in Hawaii to take infrared images days apart of the evolving clouds on the Saturn moon Titan.

The false-color infrared images to the right are those observations. From the press release:

As part of their investigation of Titan’s atmosphere and climate, Nixon’s team used JWST’s Near-Infrared Camera (NIRCam) to observe the moon during the first week of November. After seeing the clouds near Kraken Mare, the largest known liquid sea of methane on the surface of Titan, they immediately contacted the Keck Titan Observing Team to request follow-up observations.

“We were concerned that the clouds would be gone when we looked at Titan a day later with Keck, but to our delight there were clouds at the same positions on subsequent observing nights, looking like they had changed in shape,” said Imke de Pater, emeritus professor of astronomy at the University of California, Berkeley, who leads the Keck Titan Observing Team.

Using Keck Observatory’s second generation Near-Infrared Camera (NIRC2) in combination with the Keck II Telescope’s adaptive optics system, de Pater and her team observed one of Titan’s clouds rotating into and another cloud either dissipating or moving out of Earth’s field of view due to Titan’s rotation.

These images only increase my mourning for a Saturn orbiter. Since the end of Cassini’s mission in 2017, we have essentially been blind to the ringed planet and its many moons. These images, while producing excellent data, also illustrate well what we have lost.

Scientists: Viking-1 might have landed on a field of Martian tsunami debris

10:26 am

The geological history of the Viking-1 Mars landing site

As outlined in their new paper [pdf], a team of scientists now hypothesize that the features that surrounded Viking-1 when it landed on Mars in 1976 were caused by two past Martian tsunamis. Each tsunamis occurred due to an impact in the theorized ocean that is believed to have existed in this part of Mars’ northern lowland plains several billion years ago.

The graphic to the right, figure 8 from the paper, shows the hypothesized sequence of events. From the caption:

(a) Pohl crater forms within a shallow marine environment, (b) triggering tsunami water and debris flow fronts. (c) The wave fronts extensively inundate the highland lowland boundary plains, including a section ~ 900 km southwest of the impact site. (d) The ocean regresses to ~ − 4100 m, accompanied by regional glacier dissection, which erode the rims of Pohl and other craters. (e) The younger tsunami overflows Pohl and parts of the older tsunami. Glaciation continues, and mud volcanoes later source and emerge from the younger tsunami deposit. (f) ~ 3.4 billion years later, the Viking 1 Lander touches down on the edge of the older tsunami deposit.

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.

SpaceX postpones launch of Ispace’s Hakuto-R lunar lander

8:40 pm

SpaceX tonight canceled the Falcon 9 launch of the private Hakuto-R lunar lander, built by the Japanese company Ispace and carrying the UAE’s Rashid rover.

After further inspections of the launch vehicle and data review, SpaceX is standing down from Falcon 9’s launch of ispace’s HAKUTO-R Mission 1 from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. A new target launch date will be shared once confirmed.

The first stage had flown four times previously. Apparently during their standard dress rehearsal countdown and fueling before launch they detected something that cannot be immediately resolved.

InSight continues to just hold on

InSight's power levels as of November 27, 2022

The InSight science team today posted another update on the daily power levels the Mars lander’s dust-covered solar panels are producing. The graph to the right includes these new numbers.

As of Nov. 27, 2022, InSight is generating an average between 285 and 295 watt-hours of energy per Martian day, or sol. The tau, or level of dust cover in the atmosphere, was estimated at .95 (typical tau levels outside of dust season range from 0.6-0.7).

The atmosphere is definitely clearing from the dust storm that occurred in October. It also appears that not much of this dust is settling on InSight’s solar panels, since the daily power level has not dropped significantly.

Nonetheless, at these very low power levels, InSight’s future remains day-to-day. Unless it finally gets lucky and a dust devil blows the solar panels clear so more power can be generated, the mission will end should two scheduled communications sessions in a row fail to make contact.

  • Boeing says it achieved all goals during second Starliner unmanned demo mission

    • In making this statement Boeing also touted Popular Science giving it the 2022 “Best of What’s New” award. As Jay so correctly notes, “Talk about a rigged vote! Good thing I quit subscribing to PopSci five years ago.” Considering how behind schedule Starliner is, and considering the numerous other new rocket companies flying this year, this award is an embarrassment to Popular Science.

Musk’s success vs Trump’s failure

1:34 pm

Elon Musk arrives at Twitter
Musk arrives at Twitter, ready to clean house

While the buzz about Elon Musk’s takeover of Twitter has mostly focused on his effort to end censorship and the banning of conservatives, none of this constitutes his most important accomplishment there.

Yes, mandating freedom of speech at Twitter is a good thing. And yes, ending the banning of tens of thousands of conservative voices demonstrates Musk’s unwavering commitment to freedom and open debate.

However, it is his action to house-clean — to fearlessly remove from power the thugs and goons at Twitter who created these oppressive policies — that matters the most. By firing the Twitter apparatchiks who had installed that system of censorship and blacklisting, Musk has guaranteed that this censorship and blacklisting will not return easily to Twitter should his other business interests force him to pay less attention in the future.

Cool image time! The panorama above was created by two photos taken by the Mars rover Curiosity’s right navigation camera on November 30, 2022. It looks to the south, into Gediz Vallis, the slot canyon that has been the rover’s major goal since it landed in Gale Crater a decade ago.

The blue dot on the overview map to the right marks Curiosity’s present position, now on its way east after making a short detour to the west towards Gediz Vallis Ridge. The yellow lines indicate the approximate area shown by this panorama. The red dotted line in both images marks the rover’s planned future route. The white arrows indicate what scientists have labeled the marker band, a distinct smooth layer seen at about the same elevation in many places on the flanks of Mount Sharp. According to the most recent update from the science team, the rover’s next drive will place it on that marker band, the second time it has been there.

From here the rover will continue south, climbing up into Gediz Vallis.

China completes construction of world’s largest solar radio telescope array

9:36 am

China has now completed the construction of world’s largest solar radio telescope array, dubbed the Daocheng Solar Radio Telescope (DSRT), made up of 313 separate radio dishes laid out in a giant two-mile wide circle.

DSRT is focused on observing solar flares and coronal mass ejections (CMEs) which can interfere with or overload electronics and wreak havoc on and above Earth. CMEs are triggered by realignments in the star’s magnetic field that occur in sunspots, and when directed at Earth, can threaten power grids, telecommunications, orbiting satellites and even put the safety of astronauts aboard the International Space Station and China’s newly-completed Tiangong space station at risk.

Assuming China shares the data from this telescope with the rest of the world, it will function as a back-up to several very old NOAA satellites in orbit that NOAA has failed to replace. If China doesn’t share the data, however, the western world will become very vulnerable should its own satellites finally fail.

ESA’s commitment to launch Franklin rover to Mars by ’28 will require U.S. participation

9:28 am

The Europeans Space Agency’s decision to spend $725 million over the next six years to launch its Rosalind Franklin rover to Mars by 2028 will not only require the United Kingdom to develop a Mars lander, it will require U.S. participation that has not yet been secured, including the donation of a launch vehicle.

The mission’s launch this year was canceled when Russia invaded the Ukraine, thus ending all of its scientific partnerships with Europe.

The mission, now slated for launch in 2028, will primarily replace the Russian components with European ones, with several exceptions. “We have expectations that the U.S. will also contribute to this, with a launcher, a braking engine and the RHUs, the radioisotope heating units,” he said. “But the majority of the future ExoMars mission is European.”

The launch rocket will be the most expensive U.S. contribution, and to get NASA to pay for the launch will require something in return from ESA, most likely guaranteed research use of the Franklin rover by American planetary scientists. Such a deal is similar to what Europe has gotten with both Hubble and Webb, where ESA contributes something and its scientists get a percentage of guaranteed observation time.

With a rover such an arrangement is more complicated, however, which is probably why the deal is not yet settled.

SOFIA finds no phosphine in Venus’ atmosphere

9:16 am

The uncertainty of science: Using NASA’s airborne telescope SOFIA on three of its last flights, astronomers searched and found no evidence of phosphine in the Venus atmosphere, once again throwing cold water on a 2020 study that said it had detected about 20 molecules out of every billion.

Because that 2020 study and the accompanying press releases noted that on Earth phosphine is only seen in life-related processes, the general press stupidly screamed “Life found on Venus!” And as I said at that time:

This discovery is not giving us “a hint of life on Venus.” All these scientists have done is detect a chemical whose formation in Venus’ very alien environment is a mystery. Yes, on Earth this chemical comes from life related activities, but to claim that the presence of biology must explain it on Venus is not science, but witchcraft and the stuff of fantasy. We know practically nothing about the full make-up of Venus’ atmosphere, its chemistry and environment, which makes it impossible to hint at any theories, no less life.

Since then several studies (here and here and here) have suggested the phosphine detection was not what it seemed. This new Sofia data puts the nail in the coffin.

Sophia’s data also shows once again the utter unreliability of the modern mainstream press. Routinely it pushes false or weak stories, consistently showing that its reporters and editors are ignorant or naive about almost every story they cover, from science to politics. To trust its conclusions on any controversial story is to put your faith in fortune tellers.

NASA awards construction company $57 million development contract for lunar construction

9:00 am

Capitalism in space: NASA today awarded a $57 million development contract to ICON, a Texas-based company that specializes in building 3D-printed homes on Earth, to begin work on designing habitats for the Moon.

As noted in this report:

The newly announced NASA contract, granted via the agency’s Small Business Innovation Research program, will help the company mature its tech and procedures. ICON plans to use the money to learn how lunar soil, or regolith, behaves in lunar gravity using simulated samples and real ones brought back by the Apollo missions, company representatives said.

The company will also test its hardware and software on a space mission that simulates lunar gravity. And there will be an even more ambitious trial, if all goes according to plan. “The final deliverable of this contract will be humanity’s first construction on another world, and that is going to be a pretty special achievement,” [CEO Jason] Ballard said in the statement.

ICON has already built a prototype 3D-printed Mars habitat that NASA plans to use to train astronauts for long missions.

China launches military satellites using Long March 2D rocket

8:45 am

China yesterday used its Long March 2D rocket to put, according to Space Force data, three military satellites into orbit, even though China’s state run press says only one satellite was launched.

The Chinese space industry (opens in new tab) and media reports (opens in new tab)suggest that the launch carried a single Yaogan 36 remote sensing satellite. However space tracking by the U.S. Space Force’s 18th Space Defense Squadron, which focuses on space domain awareness, registered three payloads in orbit in roughly 300-mile-altitude (500 km) orbits.

China’s previous two launches involving Yaogan 36 satellites also saw satellite triplets sent into orbit, meaning Sunday’s launch was a third group of three Yaogan 36 satellites.

China typically describes Yaogan satellites as being designed for uses including gathering scientific data, conducting land surveys and monitoring agriculture. However, the secrecy surrounding the satellites leads analysts outside of China to believe that the satellites also have military capabilities and stakeholders.

The leaders in the 2022 launch race:

54 SpaceX
54 China
20 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 78 to 54 in the national rankings, while trailing the entire world combined 84 to 78.

Cool image time! The photo to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 21, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as a “layered mound.” It also shows a plethora of geological mysteries, all of which relate to the as yet not quite understood geological history of Mars.

First, note the different colors north and south of the ridgeline. According to the science team’s understanding of what these colors mean [pdf], the orange-red to the north suggests dust, while the bluish-green to the south suggests coarser materials, such as rocks and sand. Though frost and ice are generally bluer, such things are generally found on the pole-facing slopes where there is less sunlight. Thus the bluish-green material to the south is unlikely to be ice or frost, though this is not impossible, as the picture was taken in the winter and the latitude is 35 degrees north.

Why however is there such a dichotomy of rocks, sand, and dust between the north and south slopes? And if frost and ice, why is it more prominent to the south, when it should instead be more prominent to the north?

Other mysteries: Is the circular depression on the ridgetop an impact crater or a caldera? If the latter, this suggests the mound is some kind of volcano, likely mud, though lava is not excluded. If so, however, why is there no caldera on top of the ridge to the south?

The location, as shown in the overview map below, reveals other puzzles.

Today’s blacklisted American: Massachusetts hospital network to deny healthcare to those who say things it doesn’t like

12:33 pm

Mass General Brigham: hostile to free speech

They’re coming for you next: The Mass General Brigham (MGB) hospital network in Massachusetts has now established a policy that will deny healthcare to anyone who says something it doesn’t like.

The code covers not only “physical or verbal threats and assaults” and “sexual or vulgar words or actions,” but also “offensive comments about others’ race, accent, religion, gender, sexual orientation, or other personal traits” or refusal to see staff based on those traits. It frowns on “unwelcome words or actions” as well.

While patients can give their side when accused of violating the code, MGB warns that it may ask them to “make other plans for their care” in response to some violations. They might also be banned from “future non-emergency care … though we expect this to be rare.”

The code of conduct can be read here. Moreover, a scan of MGB’s website shows it to be totally invested in the agendas of critical race theory as well as diversity, equity, and inclusion. The top of its About page includes a link to a description of its “Commitment to Diversity, Equity and Inclusion,” which describes in careful terms the quota policies the hospital now follows, designed to choose minorities in hiring rather than those with better medical qualifications.

Apparently, if you go for treatment at MGB, you might not get the best or smartest care, but dammit! your doctors and nurses will be the right race or ethnicity!

Virgin Orbit’s cash problems continue

9:25 am

Because of endless delays getting a regulatory approval of a launch in the United Kingdom, Virgin Orbit has been unable to complete the 4 to 6 launches in 2022 that it had planned, and is thus experiencing serious cash shortages that has now caused it to cancel plans to sell “additional securities.”

Virgin Orbit reported third quarter revenues of $30.9 million, which exceeded the zero revenues reported in Q3 2021. The company’s net loss was $43.6 million, which was higher than the $38.6 million loss in Q3 2021.

While costs and losses have mounted, Virgin Orbit has experienced delays in increasing its launch rate. The company had planned to conduct four to six launches this year. Today, the total stands at only two with just over a month left in 2022.

Virgin Orbit’s third launch was originally scheduled to take place in last August from Spaceport Cornwall in England. The company is still awaiting a license from the UK government that would allow the launch to take place. It is the first time the government has licensed both an orbital launch and a spaceport, so the process it taking longer than anticipated.

The company had not only ramped up production of its LauncherOne rocket in anticipation of an increased launch rate, it also purchased two more 747s to act as the rocket’s first stage carrier. Those actions however were based on the ability to increase the launch rate, which has been stymied since the summer by Great Britain’s Civil Aviation Authority, which can’t seem to issue permission for Virgin Orbit to launch from a runway in Cornwall.

The canceled sale of securities appears part of the entire investment deal near the end of 2021. The cash shortages and this deal also appear connected to the decision by Richard Branson’s Virgin Group to invest $25 million in Virgin Orbit earlier this month.

Virgin Orbit officials say they intend to double their launch rate in 2023. I suspect that they have to. It is now sink or swim.

China sets new annual record with launch of manned Shenzhou-15 to space station

9:02 am

China today successfully used its Long March 2F rocket to launch three astronauts on a six month mission to its Tiangong-3 space station, setting a new annual national record for launches in a single year.

China’s previous high of 52 successfully launches was achieved last year. This launch, with about five weeks left in the year, is its 53rd in 2022.

This mission will also be the first on Tiangong-3 where there will be an overlap of two crews, with six people occupying the station for a short while.

The leaders in the 2022 launch race:

54 SpaceX
53 China
20 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 78 to 53 in the national rankings, while trailing the rest of the world combined 83 to 78.

Cool image time! The image to the right, cropped, rotated, reduced, and enhanced to post here, is without doubt one of my favorite objects that the Hubble Space Telescope has photographed over the decades. This new image combines imagery obtained by earlier Hubble cameras and the newer cameras installed in 2009.

The delicate sheets and intricate filaments are debris from the cataclysmic death of a massive star that once lived in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way. DEM L 190 — also known as LMC N49 — is the brightest supernova remnant in the Large Magellanic Cloud and lies approximately 160 000 light-years away from Earth in the constellation Dorado.

What makes this supernova remnant so visually appealing to my eye is its ghostly resemblance to a woman’s face, her hair blowing freely to the right. The original 2003 Hubble picture, shown below, has been the desktop image of my computer for almost two decades.

Today’s blacklisted American: Professor fired by University of Louisville for expressing his opinion

12:34 pm

Allen Josephson, fired for expressing an opinion
Allen Josephson, fired for expressing an opinion

They’re coming for you next: After publicly expressing his professional opinion at a 2017 Heritage Foundation conference, where he opposed the abuse of children by the queer movement that now dominates the medical community, Professor Allen Josephson was fired by University of Louisville, specifically because queer activists at the university demanded it.

From Josephson’s lawsuit [pdf], filed by the Alliance Defending Freedom:

[T]he officials at the University’s LGBT Center who became aware of and troubled at Dr. Josephson’s Heritage Foundation presentation included Ms. Stacie Steinbock (the director of the LGBT Center at the University’s Health Science Center) and Mr. Brian W. Buford (then the Executive Director of the LGBT Center). Ms. Steinbock and Mr. Buford opposed and objected to the viewpoints Dr. Josephson expressed at the Heritage Foundation.

…Ms. Steinbock and Mr. Buford (or other officials at the LGBT Center acting at their direction) contacted Dr. Christine Brady (an assistant professor in the Division) regarding Dr. Josephson’s Heritage Foundation presentation. Like Ms. Steinbock and Mr. Buford, Dr. Brady opposed and objected to the viewpoints Dr. Josephson expressed at the Heritage Foundation.

Upon information and belief, Ms. Steinbock and Mr. Buford (or other officials at the LGBT Center acting at their direction) discussed with Dr. Brady the need to ensure that some disciplinary or punitive actions were taken against Dr. Josephson due to the views he expressed at the Heritage Foundation. Ms. Steinbock and Mr. Buford (or other officials at the LGBT Center acting at their direction) repeatedly asked Dr. Brady what would be done about Dr. Josephson’s Heritage Foundation remarks. [emphasis mine]

The highlighted words illustrate the storm-trooper attitude of these queer activists. » Read more

Dragon freighter docks with ISS

9:22 am

ISS as of November 28, 2022

Capitalism in space: An unmanned Dragon freighter successfully docked with ISS yesterday, bring with it 7,700 pounds of cargo, including two new solar arrays for the station.

Two International Space Station Roll-Out Solar Arrays, or iROSAs, launched aboard SpaceX’s 22nd commercial resupply mission for the agency and were installed in 2021. These solar panels, which roll out using stored kinetic energy, expand the energy-production capabilities of the space station. The second set launching in the Dragon’s trunk once installed, will be a part of the overall plan to provide a 20% to 30% increase in power for space station research and operations.

These arrays, the second of three packages, will complete the upgrade of half the station’s power channels.

The graphic to the right shows the station as of today, with six different spacecraft docked to six different ports. No wonder there is a significant limit to the number of private missions that can fly to ISS. The needs of the station, as dictated by the international partnership of governments that run it, too often fill those ports.

This limitation will begin changing when Axiom launches its first module for ISS in about two years, followed soon thereafter by the launch of a number of other private independent stations by different American companies.

Rocket startup Agnikul Cosmos opens first commercial launchpad in India

9:09 am

Capitalism in space: The Indian rocket startup Agnikul Cosmos has completed construction on the first privately owned launchpad in India, with the first suborbital launch planned before the end of this year.

Agnikul’s infrastructure comprises a launchpad and a Mission Control center 4 kilometres away, both within ISRO’s facilities on the island located off the coast of Chennai. The space pad was designed by Agnikul, constructed over two months, and is a part of the MoU signed between ISRO and Agnikul (among other space startups) under the new regulatory authority IN-SPACe’s first batch of support projects for private companies from ISRO.

Currently, it is capable of launching Agnikul’s rocket, the Agnibaan. [emphasis mine]

The first test launch is apparently not going to be orbital, but a technology test of the launch pad, its fueling facilities, and the 3D-printed engine Agnikul has built for Agnibaan.

The highlighted words once again note the effort by the Indian government to emulate the U.S. policy in the past decade to transition from a government-run space program to a privately-run competing and chaotic space industry. This MoU (memorandum of understanding) probably resembles the first space act agreements NASA issued to SpaceX and Orbital ATK. The agreements gave private companies aid and assistance, but the companies retained full ownership of what they build, and were left free to design things as they saw fit, not as the government dictated.

That two different Indian companies, Agnikul and Skyroot, are on the verge of their first orbital launches signals that this policy is succeeding. Agnikul has tested its engines and built its launchpad. Skyroot has completed its first suborbital launch.
