SpaceX sues to get Justice’s discrimination suit thrown out on constitutional grounds

9:20 am

SpaceX on September 15, 2023 filed suit in Texas to get the Justice Department’s August 24th discrimination suit — which claims that the company discriminates against illegal aliens because it obeys State Department security regulations forbidding such hiring — thrown out on constitutional grounds.

From the complaint [pdf]:

But aside from being factually and legally insupportable, the government’s proceedings are unconstitutional for at least four reasons: (1) the administrative law judge (ALJ) adjudicating the government’s complaint was unconstitutionally appointed; (2) the ALJ is unconstitutionally insulated from Presidential authority because she is protected by two layers of for-cause removal protections; (3) the ALJ is unconstitutionally purporting to adjudicate SpaceX’s rights in an administrative proceeding rather than in federal court; and (4) the ALJ is unconstitutionally denying SpaceX its Seventh Amendment right to a jury trial.

The suit specific names two of these administrative judges, as well as attorney general Merrick Garland, as defendents. It also outlines in detail how SpaceX follows the State Department’s law protecting U.S. technology scrupulously, while hiring the most talented people of all races, including non-citizens after getting State Department permission. Even so, the company’s complaint focuses on the unconstitutionality of the Justice Department’s administrative attack, demanding its dismissal for these reasons alone.

As I noted when the Justice Department’s lawsuit was first announced,

This suit is utter garbage and puts SpaceX between a rock and a hard place. I guarantee if SpaceX had hired any illegal or refugee who was not yet a legal citizen, Biden’s State Department would have immediately sued it for violating other laws relating to ITAR (the export control laws mentioned) which try to prevent the theft of technology by foreign powers.

That SpaceX has chosen to fight this lawsuit first on constitutional grounds suggests the company has fundamentally come to the same conclusion. Musk has decided to fight back hard against Biden’s effort to squash him both politically and legally.

OSIRIS-REx makes last course correction before releasing asteroid sample return capsule

8:54 am

OSIRIS-REx’s engineers on September 17, 2023 successfully completed the last course correction necessary before releasing the sample return capsule carrying about nine ounces of material from the asteroid Bennu, set to land in Utah on September 24th.

The spacecraft briefly fired its thrusters Sunday to change its velocity by 7 inches per minute (3 millimeters per second) relative to Earth. This final correction maneuver moved the sample capsule’s predicted landing location east by nearly 8 miles, or 12.5 kilometers, to the center of its predetermined landing zone inside a 36-mile by 8.5-mile (58-kilometer by 14-kilometer) area on the Defense Department’s Utah Test and Training Range.

Details on that landing can be found here. The capsule will be coming in at speeds comparable to that of an Apollo capsule, returning from the Moon, and will use the same maneuvers and parachutes to slow its speed to only eleven miles per hour at landing. Four helicopters will than rush to recover the capsule as quickly as possible to reduce the chance the sample will be contaminated by the Earth’s environment.

OSIRIS-Rex (renamed OSIRIS-Apophis Explorer or OSIRIS-APEX) will meanwhile fire its engines and head towards the potentially dangerous asteroid Apophis, with a rendezvous scheduled in 2029.

Electron rocket fails during launch

12:07 am

Rocket Lab tonight (September 19, 2023 in New Zealand) experienced a launch failure during a launch of its Electron rocket from its New Zealand spaceport.

The failure occurred right after separation of the first stage from the upper stage. From that point all video from the rocket ceased, and the data indicated it was losing velocity, suggesting some failure of the second stage when its engines should have ignited.

This launch was to have been the second in a four-launch contract with the American company Capella Space, aimed at launching its constellation of commercial radar satellites for Earth observation.

The leaders in the 2023 launch race remain unchanged:

65 SpaceX
43 China
13 Russia
7 Rocket Lab
7 India

American private enterprise still leads China in successful launches 76 to 43, and the entire world combined 76 to 69. SpaceX by itself still trails the rest of the world combined (excluding American companies) 65 to 69.

Two galaxies merging

11:32 am

Merging galaxies
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a survey project to photograph the entire Arp catalog of 338 “peculiar galaxies,” put together by astronomer Halton Arp in 1966. From the caption:

The larger galaxy (in the left of this image) is an extremely energetic galaxy type known as a Seyfert galaxy, which house active galactic nuclei at their cores. Seyfert galaxies are notable because despite the immense brightness of the active core, radiation from the entire galaxy can be observed. This is evident in this image, where the spiraling whorls of the whole galaxy are readily visible. The smaller companion is connected to the larger by a tenuous-seeming ‘bridge’, composed of dust and gas. The colliding galactic duo lie about 465 million light-years from Earth.

Note that if you ignore the blue whorls of the left galaxy, the two bright cores of these merging galaxies are about the same size. As it is unclear how long this merger has been on-going, it is possible that the galaxy on the right, in circling the left galaxy, drew out those whorls and that tenuous bridge. Other scenarios are also possible, however, such as the galaxy on the left stripping and scattering the arms of the galaxy on the right.

Federal government continues to block the return of Varda’s commercial capsule, carrying drugs to treat HIV

9:47 am

Even as the FAA continues to block Varda from returning its capsule back to Earth, the Air Force has now joined in to block its landing at its Utah Test and Training Range, the same location NASA will use on September 24 to drop the return capsule from OSIRIS-REx, carrying material from an asteroid.

Varda originally planned to bring back a capsule containing crystals of ritonavir, a drug used to treat HIV, in mid-July. After announcing that had been delayed [due to the FAA’s refusal to issue a landing license in July], the company was looking at September 5 and 7, a source told TechCrunch. This information was confirmed by USAF.

The company declined to comment, but posted on X that the “spacecraft is healthy across all systems” and that they are continuing to collaborate with regulators to bring the capsule back to Earth. They added that the spacecraft can survive for up to a year on-orbit.

“Sept. 5 and 7 were their primary targets,” a spokesperson for the USAF said in an emailed statement. “The request to use the Utah Test and Training Range for the landing location was not granted at this time due to the overall safety, risk and impact analysis. In a separate process, the FAA has not granted a reentry license. All organizations continue working to explore recovery options.”

The spokesperson further said that Varda “is working on presenting alternate plans,” but would not elaborate further whether that meant seeking an alternate landing site. A spokesperson for the FAA told TechCrunch that Varda’s application was denied on September 6 because the company “did not demonstrate compliance with the regulatory requirements.”

“On September 8, Varda formally requested that the FAA reconsider its decision. The request for reconsideration is pending,” the spokesperson said.

The actions of these agencies is unconscionable and a outright abuse of power. There is no rational reason for the FAA to continue to deny Varda the right to bring its capsule back to Earth. Its claims of environmental impact are bogus, especially since capsules and spacecraft have been returning to Earth like this for more than three-quarters of a century. Nor is there any reason for the Air Force to have blocked the return now. Its claim of issues of “safety, risk, and impact” is utter garbage, especially since it is allowing a NASA capsule to land in this exact same facility in only days, and that capsule is carrying material from an asteroid.

One might question why Varda apparently flew its capsule prior to getting these landing approvals, but it did exactly the right thing, for two reasons. First, if it waited for approvals before flying, it would have no leverage on these power-hungry federal agencies and it likely would still be on the ground, going bankrupt (think of Virgin Orbit in the United Kingdom). This by the way is the same tactic used by SpaceX. You don’t wait on them, you put them under the gun by moving forward as fast as possible.

Second, this situation helps highlight the power grab by these agencies. While the FAA has some concerns relating to conflicts with airplane traffic, that should simply be a matter of coordination and involve no great delay. Similarly, landing on an Air Force base is merely scheduling. Since when did government agencies have the power to block a landing beyond those points? They don’t, not legally, morally, or practically.

Though I am sure most workers at the FAA and Air Force are likely trying to do their best to help
Varda, the structure of such regulatory agencies always encourages the power-hungry to grab power. The result has been endless mission creep, to the point where today no space activity can happen without some government agency sticking its nose in to demand control.

India’s Aditya-L1 solar telescope initiates some science observations

9:18 am

According to India’s space agency ISRO, its Aditya-L1 solar telescope has begun science observations with one instrument, even as it continues its journey to its final position at L1, one million miles from the Earth.

The activation of STEPS occurred on September 10, 2023, at a distance exceeding 50,000 km from Earth. This distance equates to more than eight times the Earth’s radius, placing it significantly beyond the Earth’s radiation belt region. Following the successful completion of essential health checks for the instrument, the data collection process continued until the spacecraft had travelled beyond the 50,000 km mark from Earth.

All units of STEPS are currently operating within normal parameters. A graphical representation illustrates the measurements, showcasing fluctuations in the energetic particle environment within Earth’s magnetosphere, which were collected by one of the instrument’s units.

It is expected Aditya-L1 will reach L1 in January, where it will begin round-the-clock observations of the Sun, in parallel with NASA’s Soho telescope, which has been at L1 since the 1990s.

Russian investigators pin down cause of Luna-25 failure

10:03 am

Though the investigation is not yet complete, reports out of Russia indicate that the cause of the failure of Luna-25 during an engine burn while in orbit around the Moon has been identified.

The article at the link provides the details, which involve problems with two “BIUS-L accelerometers” during the flight, which for reasons not yet understood were switching from the primary to the secondary randomly during the journey to the Moon, apparently because of some failure.

However, ahead of the fateful lunar orbit correction on August 19, both accelerometers worked correctly, but once the maneuver started, one set failed again, while the flight control system never switched to data from the second set. As a result, onboard computers were not receiving data about critical parameters required for properly completing the orbit correction, such as orientation of the spacecraft in space, velocity and altitude.

If confirmed, this crash scenario would likely implicate deficiencies in the development or testing of the flight control system and its software rather than any mechanical problem of the propulsion system, which was implied in the initial statement about the incident. [emphasis mine]

The highlighted sentence says it all. The serious quality control problems that have hampered Russia’s space efforts remain, and in fact appear systemic throughout its entire aerospace industry. In fact, this failure of a planetary probe helps explain the many difficulties Russia has been having in its war in the Ukraine, attributable to these same issues.

Virgin Galactic sets Oct 5th launch date for its fifth commercial suborbital flight in ’23

4:47 pm

Virgin Galactic today announced that the launch window for its fifth commercial suborbital flight this year and ninth overall will open on Oct 5th.

The flight will include three private passengers, two Americans and one Pakistani, and a crew of five Virgin Galactic employees.

At this point I don’t consider these suborbital flights to be very newsworthy. However, I decided to highlight this news release because of its stark contrast with Blue Origin. Even before last year’s mishap that grounded Blue Origin’s own suborbital spacecraft, New Shepard, it never flew this frequently. Virgin Galactic took far too long to begin flying (two decades), but it does appear that is now wasting no time trying to catch up.

Blue Origin meanwhile continues to drift along, accomplishing little and appearing to do even less with time.

FAA confirms: No Starship/Superheavy launch license until Interior approves

4:00 pm

The Kafkaesque Interior Department strikcs again!
The Kafkaesque Interior Department
strikcs again!

They’re coming for you next: In an email today, the FAA confirmed what I had reported yesterday, that though it hopes to issue a launch license for the next orbital test flight of SpaceX’s Starship/Superheavy rocket by the end of October, no license will be issued until Fish & Wildlife in the Interior Department agrees.

Before it is authorized to conduct a second Starship/Super Heavy launch, SpaceX must obtain a modified license from the FAA that addresses all safety, environmental, and other regulatory requirements. As part of that license application determination process, the FAA will review new environmental information, including changes related to the launch pad, as well as other proposed vehicle and flight modifications.

The FAA will complete a Written Reevaluation (WR) to the 2022 Programmatic Environmental Assessment (PEA) evaluating the new environmental information, including Endangered Species Act consultation with the U.S. Fish and Wildlife Service. If the FAA determines through the WR process that the contents of the PEA do not remain valid in light of the changes proposed for Flight 2, additional environmental review will be required. Accordingly, the FAA has not authorized SpaceX’s proposed Flight 2. [emphasis mine]

Tragically, my April prediction is coming true. This launch is almost certainly not going to occur before November, and will almost certainly be delayed until next year.

Note again that until the Biden administration, SpaceX was not required to get a detailed environmental reassessement after every Boca Chica test launch. Fish & Wildlife was not involved, as it shouldn’t be. SpaceX made its engineering investigation, the FAA reviewed it quickly, and the company launched again, at a pace of almost one test launch a month, with almost every launch resulting in a crash landing or an explosion.

Under the Biden administration the rules suddenly changed. Now, all launches are environmental concerns, even though we have empirical data for more than seventy years at Cape Canaveral that rocket launches not only do no harm to wildlife, they allow it to thrive because the spaceport creates large zones where nothing can be developed.

In other words, the Biden administration is playing a raw and cruel political game, designed to kill Starship/Superheavy. And it is succeeding, because it will be impossible to develop this rocket on time for its investors and NASA at a pace of only one test launch per year.

A triangular Martian hill

A triangular Martian hill
Click for full image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 29, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team labels an “unusual shaped hill” that is estimated to be about 20 to 40 feet high.

What makes it unusual? First, it sticks up out of the endless northern lowland plains for no obvious reason, though its shape suggests the existence of bedrock topography that is now buried by the dust and debris that coats the surface of those plains.

Second, the hill itself suggests that it formed after it was covered with debris. Note the crater near its northeast cliff. It appears that the cliff chopped off part of the crater, suggesting that the hill was once level with the surrounding terrain. Some later underground pressure pushed it upward, with its angled sides determined by existing faults.

Why those forces tilted the hill upward as it did, with only its eastern fringes raised, is a question a wide view might answer.

New analysis of Chandrayaan-1’s lunar orbital data might explain its detection of widespread surface hydrogen on the Moon

9:52 am

The Earth's magnetic field, shaped by the solar wind
The Earth’s magnetic field, shaped by the solar wind

One of the significant finds coming from India’s first lunar orbiter, Chandrayaan-1, was the detection of hydrogen in many places across the entire lunar surface, in places where it seemed impossible for hydrogen to be there, even if it was locked in a molecule like water.

Researchers in Hawaii now think they have found an explanation by linking that data to the Earth’s long magnetotail, formed by the solar wind pushing against the Earth’s magnetic field. The graphic to the right illustrates that process. The scientists focused on the kind of weathering processes that occurred both when the Moon was inside that tail, and when it was not.

Li and co-authors analyzed the remote sensing data that were collected by the Moon Mineralogy Mapper instrument onboard India’s Chandrayaan 1 mission between 2008 and 2009. Specifically, they assessed the changes in water formation as the Moon traversed through Earth’s magnetotail, which includes the plasma sheet.

“To my surprise, the remote sensing observations showed that the water formation in Earth’s magnetotail is almost identical to the time when the Moon was outside of the Earth’s magnetotail,” said Li. “This indicates that, in the magnetotail, there may be additional formation processes or new sources of water not directly associated with the implantation of solar wind protons. In particular, radiation by high energy electrons exhibits similar effects as the solar wind protons.”

In other words, the evidence suggests that the hydrogen signal seen by Chandrayaan-1 might have been a very temporary implacement of that hydrogen by the solar wind, which ceases during the Moon’s periodic passages through the magnetotail. The Moon’s harsh environment then causes that hydrogen to vanish, only to reappear when it is once again exposed to the solar wind.

None of this is confirmed, so some skepticism is required. If true, however, it would provide further evidence that the hydrogen signal seen at the lunar poles that scientists hope is evidence of ice in the permanently shadowed craters might be nothing of the sort, and we shall find little ice there.

Germany signs Artemis Accords

9:26 am

Germany today finally signed the Artemis Accords, becoming the 29th nation to do so. More important, its signing puts most of Europe within the accords, as well as all of the major players in space except for China and Russia.

The full list of signatories to the Artemis Accords is now as follows: Argentina, Australia, Bahrain, Brazil, Canada, Columbia, Czech Republic, Ecuador, France, Germany, India, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

We now can essentially see the alliance that will compete with China, Russia, and the handful of third world leftist nations such as Venezuela and South Africa. Though there are some nations on this list that have not flown in space and have a very weak infrastructure for space (Nigeria, Romania, and Ecuador for example), most of the signatories have major aerospace industries with a strong space component. More important, while the Biden administration has been deemphasizing the original conception of the accords, aimed at strengthening property rights in space, the members of the alliance are still mostly capitalist countries, with legal systems that support individual rights.

On the other side are nations that have traditionally or are now pushing for communism and strong authoritarian rule.

Thus, we can now see the rough outline of the political competition that will exist as the solar system is explored and colonized in the coming centuries.

Polygons and scallops in the high mid-latitudes of the Martian lowland plains

Polygons and scallops in the high mid-latitudes of Mars
Click for original image.

Cool image time! Only yesterday I posted an image of polygons in the dry equatorial regions of Mars, where little evidence of near-surface ice is found and are thought to be the remnants from a long-dried lakebed.

Today we take a look at some polygons in the mid-latitudes of the icy northern lowland plains, where near-surface ice appears ubiquitous and as it sublimates away with the changing seasons causes all kinds of strange formations, including polygons.

The picture to the right, cropped, reduced, and sharpened to post here, is a good example, centered on a 0.6-mile-wide bright crater that appears to be filled with glacial ice. The image was taken on June 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and is located at 44 degrees north latitude on the western edge of Utopia Basin. As noted by the MRO science team in 2006 for a different MRO picture with similar features:

Webb captures new infrared image of bi-polar jets shooting from baby star

10:54 am

HH 211 as seen by Webb
Click for original image.

Using the Webb Space Telescope, astronomers have taken a new infrared image of the baby star Herbig-Haro 211 (HH 211), known best for the bi-polar jets that shoot out in opposite directions at very great speeds.

That picture is to the right, reduced and sharpened to post here, and has about 5 to 10 times the resolution of previous infrared images.

The image showcases a series of bow shocks to the southeast (lower-left) and northwest (upper-right) as well as the narrow bipolar jet that powers them. …. The inner jet is seen to “wiggle” with mirror symmetry on either side of the central protostar. This is in agreement with observations on smaller scales and suggests that the protostar may in fact be an unresolved binary star.

Earlier observations of HH 211 with ground-based telescopes revealed giant bow shocks moving away from us (northwest) and moving towards us (southeast) and cavity-like structures in shocked hydrogen and carbon monoxide respectively, as well as a knotty and wiggling bipolar jet in silicon monoxide. Researchers have used Webb’s new observations to determine that the object’s outflow is relatively slow in comparison to more evolved protostars with similar types of outflows.

The team measured the velocities of the innermost outflow structures to be roughly 48-60 miles per second (80 to 100 kilometers per second). However, the difference in velocity between these sections of the outflow and the leading material they’re colliding with — the shock wave — is much smaller. The researchers concluded that outflows from the youngest stars, like that in the center of HH 211, are mostly made up of molecules, because the comparatively low shock wave velocities are not energetic enough to break the molecules apart into simpler atoms and ions.

The baby star at the center of these jets, about a 1,000 light years away, is estimated to be only a few ten thousand years old, and presently has a mass less than a tenth of the Sun. With time it will accrete more matter and become a full-sized star.

23 Indian companies bid for ownership of ISRO’s SSLV rocket

10:39 am

In the Modi government’s push to transition its aerospace industry from one controlled by its space agency ISRO to one that is controlled by no one and is instead a competitive commercial market owned by private companies, it had recently proposed transferring ownership of ISRO’s SSLV rocket to a private company, and requested applications from private companies interested in doing so.

It now appears that twenty-three Indian companies have entered their names in the hat.

Chairman of Indian National Space Promotion and Authorisation Centre (IN-SPACe) Pawan K Goenka said that they are keen to see how the private sector uses the Small Satellite Launch Vehicle (SSLV) technology. “There has been a tremendous response, 23 companies have (so far) shown interest in applying for this technology. Of course only one of them will get it,” he said.

IN-SPACe, an autonomous nodal agency under the Department of Space (DOS), formed in 2020 to promote, enable, authorise and supervise non-government entities (NGEs) to undertake space activities, had in July floated an Expression of Interest (EoI) for transfer of technology (ToT) of SSLV with the last date to respond to it being September 25.

“Technology transfer is something we are working on very aggressively, because we really want to see how ISRO’s technology is leveraged by private sector. A lot is happening in that area and the biggest one is of course SSLV technology transfer, where we are transferring the launch vehicle lock, stock, and barrel completely to the private sector,” Goenka said.

As there is still several weeks left before the deadline, it is possible other companies will submit offers. Whichever company gets the rocket will immediately become a significant player in the global launch market, able to offer a very cost effective rocket for commercial launches. It will certainly be able to match Rocket Lab right off the bat.

German govenment blocks Chinese takeover of startup satellite company

10:29 am

The German govenment today blocked the completion of a stock deal that would have transferred almost complete ownership of the startup satellite company KLEO Connect to a Chinese firm.

The cabinet agreed a decision by the economy ministry not to let Shanghai Spacecom Satellite Technology, which already has 53% of the company, acquire the 45% minority stake of German company EightyLeo, according to the sources.

KLEO Connect wants to establish a network of more than 300 small, low earth orbit satellites to be fully operational by 2028 along with the ground infrastructure to provide global communications services – similar to SpaceX with its project Starlink. [emphasis mine]

It appears this decision might be a bit late, considering that this Chinese pseudo-company, undoubtably working under the supervision of the Chinese communists, already owns a majority stake. That lateness however appears to be part of the German government’s decision in the last year to toughen its stance on China.

Starship/Superheavy 2nd test launch likely delayed until next year by federal bureaucracy and White House

9:52 am

Starship stacked on Superheavy, September 5, 2023
Starship stacked on Superheavy, September 5, 2023,
when Elon Musk said it was ready for launch

They’re coming for you next: While answering questions from reporters at a conference yesterday on when SpaceX might get its next Starship/Superheavy launch license, FAA acting chief Polly Trottenberg said she hoped that license will be awarded by October, but then slipped in one minor additional detail that had not previously mentioned or required:

SpaceX would still need a separate environmental approval from the U.S. Fish and Wildlife Service before a launch. Trottenberg did not say how long that might take.

Not surprisingly, the story from Reuters buries this detail, spinning the story to make it seem that the FAA is eager to help SpaceX launch. Similarly, this NasaSpaceFlight.com story (a space news outlet which has also tried to spin things to make the delays appear the fault of SpaceX) fails to even mention this detail.

SpaceX is now destacking Starship from Superheavy (live stream here).

I predicted in the spring that intransigence from the federal bureaucracy, controlled by the Biden administration, would likely delay this launch well past August, and likely into next year. I also said I would be thrilled if my cynical prediction turned out to be wrong.

Sadly, it looks like that prediction will be correct, and in fact might have actually been conservative. » Read more

Moon’s south pole permanently shadowed regions are younger than expected

1:26 pm

Map of Moon's south pole, with permanently shadowed regions indicated
Click for original image.

A new long range model of the Moon’s orbit and rotational tilt now suggests that the permanently shadowed regions (PSRs) in its south polar regions are much younger than previous predicted, which reduces the likely amount of ice that has been preserved there.

The map of the south pole region to the right, reduced, sharpened, and annotated to post here, shows the locations of those shadowed regions, with their predicted ages indicated by the colors (Gyr = billion years). Note that the Nova-C lander, planned for launch in mid-November, will land somewhat near some relatively young PSRs, as indicated by the red cross. From the press release:

“We calculated the lunar spin axis orientation and the extent of PSRs based on recent advances for the time evolution of the Earth-Moon distance,” he said. Early in its history, the Moon (which is 4.5 billion years old) was bombarded by comets and volcanism released water vapor from its interior, but continuously shadowed areas started to appear only 3.4 billion years ago. By that time these processes had started to die down, so most of the water that was delivered to the Moon or outgassed from its interior could not have been trapped in the polar regions. Any ice in the polar regions today must have a more recent origin.

“We have been able to quantify how young the lunar PSRs really are,” Schorghofer said. “The average age of PSRs is 1.8 billion years, at most. There are no ancient reservoirs of water ice on the Moon.”

Since other data suggests the presence of ice, it is possible that these reserves are regularly renewed by the arrival of impacts. It also suggests however that there might be less ice available than hoped. Above all, the red colored regions appear to be the most valuable real estate to explore first.

Note: The landing sites for both India’s Vikram lander and Russia’s Luna-25 lander were well beyond the map’s upper right edge, far outside the region where any permanently shadowed craters are located. The news outlets that talked about finding water or ice on either mission were simply illustrating their ignorance and sloppy reporting.

The drying out of Mars’ tropics

The drying out of Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 26, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team calls the features surrounding these small 20 to 60 foot high hills “polygon features,” an apt description and a geological feature that is seen in many places on Mars.

When these features are found in the icy higher latitudes, it is believed they are formed in connection to the freeze-thaw cycle that causes cracks in the near surface ice. When found in the dry equatorial regions, where these polygons are located, they are usually thought to be ancient evidence of past standing water that left behind these cracks, much like the cracks seen in mud after the water has evaporated away on Earth.

The formation of these tiny hills is a bit more complex.

Chandra: New X-ray composite images of galaxies and supernovae remnants

Click for original image.

The science team for the Chandra X-Ray observatory today released five new composite images of two galaxies, two supernovae remnants, and the center of the Milky Way, combining data from multiple telescopes looking in radio, infrared, optical, and X-ray wavelengths.

The image to the right, reduced and sharpened to post here, is one of those pictures. From the press release:

As the galaxy moves through space at 1.5 million miles per hour, it leaves not one — but two — tails behind it. These tails trailing after ESO 137-001 are made of superheated gas that Chandra detects in X-rays (blue). ESO’s Very Large Telescope shows light from hydrogen atoms (red), which have been added to the image along with optical and infrared data from Hubble (orange and cyan).

The inset shows just the Hubble optical image, reduced by about 50%, to get a clearer sense of the galaxy itself. It appears to be a jelly-fish galaxy, flying through space at right angles to its plane and with tendrils of stars trailing off below.

The other four images are as interesting. The full set, including separate images in the individual wavelengths prior to combination, can be found here.

Update on the status of Vulcan, Ariane-6, and New Glenn

9:48 am

Link here. This excellent article is focused on whether these three new rockets, none of which has yet completed its first test flight, will be able to meet their launch contract obligations with Amazon, which needs to launch at least 1,600 satellites of its Kuiper broadband constellation by July 2026 to meet its FCC license requirements. Those requirements also obligate Amazon to have the full constellation of about 3,200 satellites in orbit by July 2029.

The launch contracts to these three untried rockets was the largest such contract ever issued, involving 83 launches and billions of dollars.

To sum up where things stand in terms of the first test launch of each rocket:

New Shepard remains grounded, a year after launch failure

9:24 am

More than five months after completing its mishap investigation of the New Shepard launch failure one year ago, Blue Origin’s suborbital spacecraft remains grounded, with no clear indication when it will fly again.

In March, Blue Origin announced the results of its anomaly investigation: The nozzle on the first stage’s single BE-3PM engine suffered a “thermo-structural failure,” which caused a thrust misalignment and brought the mission to a premature end.

In its March 24 announcement, Blue Origin said that it had begun implementing some corrective actions, “including design changes to the combustion chamber and operating parameters, which have reduced engine nozzle bulk and hot-streak temperatures.” The company also stressed that it expected to return to flight “soon,” with a re-launch of those same 36 research payloads.

Almost six months later, that “soon” has translated into “someday.” It seems the slow pace of everything Blue Origin does has now taken over its one successful operational product. It has released no information about a new flight schedule, or even the present status of the spacecraft.

The result? Even though Blue Origin was flying commercial suborbital flights regularly about two years earlier that Virgin Galactic, the latter company has now completed more flights. This slow pace is not how a commercial company driven to earn profits and compete successfully operates. In the end it drives away customers, while ceding market share to competitors.

Astronomers discover two new polar-ring galaxies

9:13 am

Polar ring galaxy
Click for original image.

Using a combination of optical and radio telescopes as well as computer modeling, astronomers think they have identifed polar rings of gas orbiting two different galaxies, adding these to the relatively small population of known polar-ring galaxies.

Polar ring galaxies are unique in that they have an outer ring of gas and stars circling the galaxy at right angles to its plane. A composite image of one of these new galaxies is to the right, cropped, reduced and sharpened to post here. From the press release:

Jayanne English, a member of the WALLABY research team and also an expert in astronomy image-making at the University of Manitoba, developed the first images of these gaseous polar ring galaxies using a combination of optical and radio data from the different telescopes. First, optical and infrared data from the Subaru telescope in Hawaii provided the image for the spiral disk of the galaxy. Then, the gaseous ring was added based on data obtained from the WALLABY survey, an international project using CSIRO’s ASKAP radio telescope to detect atomic hydrogen emission from about half a million galaxies.

The creation of this and other astronomical images are all composite because they include information that our eyes can’t capture. In this particular case, the cold hydrogen gas component, invisible to the human eye, is seen in radio “light” using CSIRO’s ASKAP. The subtle colour gradient of this ring represents the orbital motions of the gas, with purple-ish tints at the bottom tracing gas that moves towards the viewer while the top portion moves away. The emission from the ring was separated from the radio emission emanating from the disk of the galaxy using virtual reality tools, in collaboration with Professor Tom Jarrett (University of Cape Town, South Africa).

As the abstract of the research paper notes, the computer models used “show that the data are consistent with PRGs [polar-ring galaxies] but do not definitively prove that the galaxies are PRGs.” There is much uncertainty, as it is difficult to determine the orientation of some rings relative to their galaxy’s plane.

Nonetheless, these result suggest polar ring galaxies might be more common, and thus might help refine the theories of galaxy formation and merger.

Starlink and SES team up to provide broadband service to cruise lines

8:53 am

SpaceX’s Starlink constellation and SES’s satellites in higher orbits are forming a partnership to provide cruise ships better global coverage for broadband.

The SES Cruise mPowered + Starlink service would mostly use SpaceX’s low Earth orbit network (LEO) and satellites in medium Earth orbit (MEO) from SES. In northern and southern regions, apart from the poles where there is no service, SES vice president of product management for maritime products Gregory Martin said their joint offering would leverage its geostationary satellites.

SES would sell and manage the multi-orbit service when it becomes operational later this year and SpaceX would get a cut of the sales, Martin told SpaceNews in an interview.

It appears by partnering their services, the two companies make the deal better for cruise companies.

Weird rocks on Mars

1:02 pm

Weird rocks seen by Curiosity and Perseverance
For original images, go here and here.

Time for two cool images, this time from both of the American rovers on Mars.

The left picture above was taken on September 9, 2023 by the high resolution mast camera on Curiosity. It shows what appears to be a many-layered but rounded rock which appears typical of the many boulders that cover the terrain through which Curiosity is presently traveling. In the past the layered rocks that Curiosity has observed lower on the flanks of Mount Sharp have not been rounded. Instead, the delicate layers have often extended outward at the rock’s edges, almost like paper or threads. For some reason, the layers in the rocks here have been eroded smooth, suggesting they were once covered by flowing water or ice, able to round the rough edges in a way that Mars’ thin atmosphere can’t.

What is puzzling is the location, higher on Mount Sharp. One would expect the reverse, with such erosion more typical lower on the mountain and uneroded delicate layers more common higher on the mountain.

The right picture above was taken on September 8, 2023 by one of the high resolution mast cameras on the rover Perseverance in Jezero Crater, about 5,000 miles to west of Curiosity. It shows a rock whose shape is so strange it is hard to fathom a geological process that would result in this form. Possibly the rock was a surface layer on a larger round boulder, and the normal freeze-thaw cycle of Mars caused it crack off as one piece. The lump in the middle however makes this explanation questionable.

Also puzzling is the curved shape. On Mars almost no geological layers have been found that are curved. They are generally flat and horizontal, reflecting the lack of tectonic processes that on Earth often twist and squash layers.

Ingenuity completes 58th flight on Mars

11:16 am

Overview map
Click for interactive map.

Ingenuity yesterday successfully completed its 58th flight on Mars, flying 571 feet to the northwest for 107 seconds at a height of 33 feet.

The overview map above shows with the green line the approximate route of the helicopter. Though the Ingenuity engineering team has updated the flight log (at the link above), the route has not yet been added to the Perseverance interactive map. I am guessing at that route based upon the flight plan posted on September 7, 2023, which stated the rover would head northwest as well as image science targets. That suggests it was flown above Perseverance’s planned route, as indicated by the red dotted line.

This particular flight was different than recent flights, which have generally lasted slightly longer and covered a slightly longer distance, probably so the helicopter could find a safe landing spot. This time Ingenuity landed about 23 seconds early, though the distance traveled was still slightly longer. The difference once again was almost certainly caused by the helicopter’s software picking a good landing spot. It just got above its planned landing spot sooner than expected, found a good pad, and then landed.

The blue dot marks Perseverance’s present location. It is presently moving west to reach what the scientists consider an important geological contact between two layers.
