    • Having the ability to change is not in itself a bad thing, but indecisiveness can be a curse. At present it is not clear which it is for this particular Chinese rocket project. Jay’s comment: “Dr. Long [the designer] … can’t decide which plans to steal and build.”

Jay asks forgiveness for the lateness today of these quick links, as he was overwhelmed with work at his real job. I say, no apology required. Thank you Jay!

Layers upon layers on Mars

3:47 pm

Layers on Mars
Click for original image.

Today’s cool image once again illustrates that the geology of Mars will almost certainly center on a study of layers, as increasingly the orbital and rover images are telling us that the red planet is covered with innumerable layers, one after another, each created by another cycle, some seasonal, some global, and some related to climate and the planet’s fluctuating rotation tilt as well as its orbit around the Sun. And some might also be random volcanic events, unrelated to the cycles.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 10, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled by the science team “Layering in western Arabia Terra”, this section only shows a small amount of the layering visible in the full image. From east to west the ground rises in a series of terraces, each representing a different layer of distinct geology.

Today’s blacklisted American: University tells student it will block her speech, even off campus and on her private time

1:56 pm

Elisa Carroll: censored by Villanova
Villanova student Elisa Carroll

They’re coming for you next: Villanova University recently told one of its students, Elisa Carroll, that it has the right to stop her from distributing pro-choice literature or contraceptives, even if she is doing it on a public sidewalk off campus and on her own time.

Carroll, recognizing that as a religious college Villanova would not provide contraceptives for its students, wanted to make them available anyway. She also recognized that she should not do it on campus, in order to respect the university’s stance. Instead, she decided to set up an unaffiliated organization that would offer such things close to but off-campus.

The university decided this was still unacceptable, and moved to forbid it.

Villanova Director of Student Involvement JJ Brown told Carroll the university would prevent her from distributing the contraceptives on a public sidewalk near campus. Brown told her that given the sidewalk’s proximity to campus and because Carroll is a Villanova student, the university could prevent her from promoting any contraceptive advocacy organizations there, including by handing out contraceptives.

In response, Carroll asked for help from the Foundation for Individual Rights and Expression (FIRE), which immediately fired off a letter to Villanova, telling it in no uncertain terms the illegality as well as the immorality of its threat.

The panorama above, cropped, enhanced, and annotated to post here, was taken by left navigation camera on the Mars rover Perseverance on February 27, 2023, looking ahead at its future path on the delta that flowed into Jezero Crater sometime into the past. The arrow points at Ingenuity, now sitting ahead of the rover after completing its 46th flight sometime this weekend.

On the overview map to the right, Perservance’s present location is indicated by the blue dot. The green dot marks Ingenuity’s position, and the yellow lines indicate the approximate area viewed by the panorama above. The red dotted line indicates Perseverance planned future route, though it is likely the science team will make many side trips along the way. The bigger dots are points of special interest, where the scientists hope to drill for core samples.

The ridge on the right is the rim of Belva Crater. The higher mountain behind it is likely the rim of Jezero Crater itself, about four miles away. The helicopter sits about 250 feet away.

Unlike the rocky terrain where Curiosity is presently traveling in the foothills of Mount Sharp in Gale Crater, the terrain here in Jezero Crater appears much more benign, almost like a sand desert of dunes. This is not sand, nor are the hills dunes, but wind erosion and dust appear to have smoothed and hidden the geology more than in Gale Crater.

ESA invites private companies to build lunar satellites for communications and navigation

9:47 am

Capitalism in space: The European Space Agency (ESA) has now invited European and Canadian companies to build the lunar communications and navigation satellites that will be needed to serve the many future manned and unmanned missions presently being planned by the U.S. and Europe.

Under its Moonlight programme, ESA is inviting space companies to create these lunar services.

By acting as an anchor customer, ESA is enabling space companies involved in Moonlight to create a telecommunication and navigation service for the agency, while being free to sell lunar services and solutions to other agencies and commercial ventures.

Once Moonlight is in place, companies could create new applications in areas such as education, media and entertainment – as well as inspiring young people to study science, technology, engineering and maths, which creates a highly qualified future workforce.

According to the press release, almost 100 companies have already expressed interest.

It is however unclear how much freedom the companies will have in designing and creating these satellites, based on ESA’s own descriptions of the project. It appears that ESA wants to design them, and is simply looking for private companies to build them. Under this arrangement, ownership will not belong to the companies, even if they are given the freedom to make money selling the capability to others. In fact, past history suggests that in the end, ESA will eventually retract this part of the deal, because of its desire to fully control the satellites it designed.

NASA names solar scientist as its new science head

9:32 am

NASA today announced the appointment of solar scientist Nicola Fox as the chief of the agency’s science division, taking over from solar scientist Thomas Zurbuchen.

Fox’s actual qualifications for the job are stellar.

Born in Hitchin, Herefordshire, England, Fox received a B.S. in physics from The Imperial College of Science, Technology and Medicine in London, an M.S. in Telematics and Satellite Communications from the University of Surrey, and returned to Imperial College London for her Ph.D. in Space and Atmospheric Physics. She worked at NASA’s Goddard Space Flight Center before joining APL in 1998.

At NASA Fox has led its the solar science division, as well as been the project scientist for the Parker Solar Probe, presently orbiting the Sun.

For the Biden administration and our modern culture that unfortunately always seems more focused on race and gender, the only thing that really matters about Fox however is her sex, a fact that the linked article seems obligated to mention in this manner:

Only one other woman, Mary Cleave, an environmental research engineer and former astronaut, has headed [the science division] in the agency’s almost 65-year history.

How evil! Our racist society oppressed women all those years, holding them back!

In fact, it is actually becoming increasing difficult for any white and heterosexual male to get major management jobs anywhere. The race- and gender-baiters always talk about getting rid of the “glass ceiling,” but in their obsession with giving jobs to woman and minorities, they have simply placed it over others.

Ispace provides update on its Hakuto-R1 lunar lander on the way to the Moon

9:09 am

Lunar map showing Hakuto-R1's landing spot
Hakuto-R1’s planned landing site is in Atlas Crater.

The CEO of the Japanese company Ispace yesterday gave a media briefing on the status of its Hakuto-R1 lunar lander, essentially stating that the spacecraft is doing fine and is on target to land on the Moon at the end of April as planned.

Ispace CEO Takeshi Hakamada said during a media briefing Monday that the flight has provided operational data that will inform subsequent missions. “We have acquired tons of data and know-how” on the lander and its subsystems, he said. “They are very viable assets for ispace.”

That includes information on the lander’s structural performance during launch and deployment, as well as the performance of thermal, communication and power subsystems. “It’s almost impossible to assume everything perfectly before the mission,” Hakamada said. “It is inevitable to face off-nominal events.” Some off-nominal events in the mission so far include thermal temperatures hotter than the company anticipated and a brief, unexpected issues with communications after the lander deployed from the Falcon 9. The thermal issues have not affected operations.

This mission, while carrying commercial payloads such as the UAE’s Rashid lunar rover, is mainly aimed at finding out these engineering details in order to make the next two missions in ’24 and ’25 more likely to succeed. The ’24 mission is also planned as a test mission, but it will carry commercial payloads for both Japanese and Taiwanese customers. On the ’25 mission, the main customer is NASA.

SpaceX’s Falcon 9 launches 21 second generation Starlink satellites

4:33 pm

SpaceX today successfully launched 21 second generation Starlink satellites, dubbed V2-minis because they are smaller than the full version that will be launched on Starship.

The Falcon 9 rocket used a first stage flying on its third flight. It successfully landed on a drone ship in the Atlantic. The fairings were completing their second flight.

The 2023 launch race:

13 SpaceX
7 China
3 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise now leads China 14 to 7 in the national rankings, and the entire world combined 14 to 12. SpaceX alone leads the entire world combined 13 to 12.

The shift away from government schools, at all levels, accelerates

3:51 pm

Parents are rejecting this in droves
Parents are rejecting this mantra in droves

It has been clear for decades that the public schools in most major urban areas — all of which have been run by Democrats — have been failing badly at their primary task of educating children. Two recent stories underlined this failure.

First, in Baltimore a study found that not one student in twenty-three of the city’s schools was proficient in math.

Through an analysis of 150 Baltimore City Schools, 23 of them, including 10 high schools, eight elementary schools, three high schools and two middle schools, no students met math grade-level expectations, according to a report by Project Baltimore. Approximately 2,000 students took the state administered math exams that tested proficiency levels.

…An additional 20 schools in the district had no more than two students proficient in math, Project Baltimore reported. Another three schools in the district, which are for incarcerated students and students with disabilities, had no students that met grade-level expectations.

Essentially, just under one third of all of Baltimore’s public schools failed to teach any of their students math. Period. For any school system to accept this level of failure is beyond disgusting. Everyone who works for Baltimore’s schools should be canned, now.

Then, just days later, another story revealed that fifty-five of Chicago’s public schools were also totally incompetent at teaching math or reading, and should find other work.

Drilling success for Curiosity in the marker layer?

The fifth drill hole in the marker band
Click for original image.

It appears from the most recent image sent back from Curiosity today of its February 25, 2023 attempt to drill into the marker layer on Mount Sharp — the fifth such attempt — the rover finally succeeded in getting deep enough to collect sufficient sample material for analysis.

That image is to the right, cropped, reduced, and sharpened to post here. Note that it is not yet confirmed from the science team that this drill attempt was deep enough. What makes this particular drilling attempt intriguing is how the many thin layers of the marker layer responded to the stress of the drill. The top layer cracked like a plate and separated from the adjacent lower layer during drilling. It apparently was hard enough to retain most of its structure, and rather than crumble the drill stresses caused a large section to break away and lift off.

The panorama above, cropped and reduced to post here, was taken the same day from this location, produced from 37 photos taken by the rover’s right navigation camera. The cropped section above looks forward at what I previously labeled “a Martian hill of pillows.” The overview map below shows the context of this panorama.

Galaxies afloat in space

10:00 am

Galaxies afloat in space
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken by the Hubble Space Telescope and released today. It is part of a survey project studying what the press release calls “jellyfish galaxies,” spiral galaxies that have long extended arms.

As jellyfish galaxies move through intergalactic space they are slowly stripped of gas, which trails behind the galaxy in tendrils illuminated by clumps of star formation. These blue tendrils are visible drifting below the core of this galaxy, and give it its jellyfish-like appearance. This particular jellyfish galaxy — known as JO201 — lies in the constellation Cetus, which is named after a sea monster from ancient Greek mythology. This sea-monster-themed constellation adds to the nautical theme of this image.

On the lower left is what the press release calls an elliptical galaxy, probably because it has no obvious arms. It is however shaped more like a spiral galaxy, since ellipticals tend to be spherical. If you look close you will also notice at least five-plus other galaxies in this picture, all smaller either because they are much farther away or are simply much smaller.

New company aims at providing floating ocean-going spaceports for rocket companies

9:29 am

A new startup, The Spaceport Company, is building a floating ocean-going spaceport for smallsat rocket companies, with the company’s long term goal to provide a range of floating spaceports for rockets of all sizes.

The Spaceport Company is planning to demonstrate a sea-based launch platform in May, conducting four sounding rocket launches from a modified ship in the Gulf of Mexico. “That will help us prove out our logistical, operational and regulatory procedures,” said Tom Marotta, founder and chief executive of the company, during a panel at the SpaceCom conference Feb. 23.

Those tests will be a precursor to developing a full-scale sea-based platform, based on a ship design called a liftboat. That ship can sail to a location and lower legs to anchor itself on the seafloor. The boat can then lift itself out of the water and serve [as] a launch platform.

That first orbital platform would provide launch services for smallsat rockets capable of launching up to one ton, and if the company’s suborbital test launches go well and further investment capital arrives, could be operational by 2025.

Astroscale raises $76 million in private investment capital from Mitsubishi, space tourist Maezawa, and others

9:20 am

The Japanese startup Astroscale, which is focused on removing orbital space junk and robotic satellite repair, has raised $76 million in private investment capital, bringing the total it has raised from private sources to $376 million.

Astroscale Holdings Inc. (“Astroscale”), the market leader in satellite servicing and long-term sustainability across all orbits, has closed a Series G round with more than U.S. $76 million in funding from new investors Mitsubishi Electric, Yusaku Maezawa, Mitsubishi UFJ Bank, Mitsubishi Corporation, Development Bank of Japan, and FEL Corporation.

The investors are of interest. Billionaire Maezawa, who has already flown to ISS as a tourist and has purchased a lunar mission on SpaceX’s Starship, contributed $23 million of the $76 million. Mitsubishi in turn has contributed at least $25 million. Both suggest Astroscale is now on very solid financial ground.

It also appears that the big players in Japan see Astroscale’s business plan as viable and expected to be profitable.

Manned Endeavour launch tonight on Falcon 9 scrubbed at T-2:12

12:05 am

UPDATE: New launch date, still tentative pending investigation into the technical issue that forced tonight’s scrub, is now March 2, 2023, at 12:32 am Eastern.

The fourth manned launch of SpaceX’s Endeavour Dragon capsule, carrying four astronauts, was scrubbed tonight at T-2:12 because of an issue with ground ignition system of the rocket. As of posting no additional details had been released, as the launch team was in the process of standing down, unloading the fuel from the rocket in preparation for getting the astronauts out of the capsule safely.

Assuming the issue can be fixed quickly, there is another launch opportunity tomorrow, February 28, at 1:22 am (Eastern). For SpaceX a launch scrub for technical reasons has become remarkably rare. In fact, the only other scrub since 2020 for technical reasons took place in July 2022. During that time the company successfully launched more than 100 times, thus getting off the ground as scheduled about 99% of the time, excluding weather delays.

While the Endeavour capsule will be making its fourth flight, when this launch finally takes place the rocket’s first stage is a new stage and will be making its first flight. This has also become a relatively rare event for SpaceX. In 2022, of the company’s 61 launches, only three used new first stages. So far this year this launch will be the second new stage to fly, out of the thirteen launches so far.

IBEX in safe mode

11:38 am

On February 18, 2023, NASA’s Interstellar Boundary Explorer (IBEX) went into what the engineers have dubbed “contingency mode”, which seems to be a variation of safe mode, due to a computer issue that is preventing the spacecraft from accepting commands.

While fight [sic] computer resets have happened before, this time the team lost the ability to command the spacecraft during the subsequent reset recovery. The team also was unsuccessful in regaining command capability by resetting ground systems hardware and software.

Flight software still is running, and the spacecraft systems appear to be functional. However, while uplink signals are reaching the spacecraft, commands are not processing. If the mission team’s efforts to find and remedy the loss of command capability remain unsuccessful, IBEX will perform an autonomous reset and power cycle on March 4.

IBEX was designed to study the boundary between the interstellar space and the solar system, and do it somehow from Earth orbit.

Where to get legal help if you have been illegally blacklisted

4:39 pm

Today’s blacklist column is a follow-up of an earlier column from August 2022, when I provided a detailed list of the various legal non-profit firms that now take on cases to defend the blacklisted. The number of such firms has grown, and I decided it was time to provide a new more complete list.

These non-profit law firms are all dedicated to fighting the left’s shameless effort to illegally and immorally blacklist, blackball, censor, and destroy its opposition, and have been increasingly successfully in winning their cases. The list, though obviously not all inclusive, describes what appear to be the most active and successful non-profit law firms presently winning first amendment cases nationwide. (Note too that the ACLU is not on the list, as that organization a long time ago abandoned its foundational goal of protecting free speech and has instead become an agent acting to increase the left’s power over ordinary citizens.)

In choosing among these law firms, make sure you review their entire website and the many cases they are handling. Some firms might be less appropriate for your situation, and it is necessary on your part to do the due diligence to figure this out.

Meandering ridges in Greg Crater

Meandering ridges in Greg Crater
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on November 29, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label “curved ridges.”

These might be inverted channels, the beds on which either water or ice flowed, compacting it down so that it became very resistant to erosion, and thus remains when the surrounding terrain was worn away. However, none of them seem to follow any grade. A more likely explanation is that these are ancient moraines, the debris pile pushed ahead of a glacier and then left behind when the glacier goes away.

The location is the reason I favor this explanation.

Puerto Rico’s Ports Authority is looking for an operator to run the island’s own spaceport

10:09 am

Ceiba spaceport map
The arrow points to the city of Ceiba

Puerto Rico’s Ports Authority has now issued a call for proposals from potential operators of the spaceport the authority wishes built at an airport in the town of Ceiba on the island’s eastern tip.

The developer — which would operate the Spaceport for several years, depending on the negotiation — would design and build the infrastructure needed for horizontal launches at JAT, using private capital, equity and investment.

…“Vertical launches in Puerto Rico are challenging, considering the population density, among others. However, we want to do a feasibility study for vertical launches in Puerto Rico, with an emphasis on the use of barges and launches in high seas,” the agency stated in the RFP.

Note that the first goal would be to make the airport usable for rocket companies that use an airplane for their first stage, such as Virgin Orbit and Northrop Grumman. The next step would be figure out where a vertical launchpad could be safely and practically established.

Many carbon-based molecules identified in Ryugu samples

9:53 am

Researchers in Japan, Europe, and the U.S. have now identified many carbon-based molecules in the Ryugu samples brought back to Earth by Japan’s Hayabusa-2 asteroid probe. From their paper, published in Science yesterday:

We identified numerous organic molecules in the Ryugu samples. Mass spectroscopy detected hundreds of thousands of ion signals, which we assigned to ~20,000 elementary compositions consisting of carbon, hydrogen, nitrogen, oxygen, and/or sulfur. Fifteen amino acids, including glycine, alanine, and α-aminobutyric acid, were identified. These were present as racemic mixtures (equal right- and left-handed abundances), consistent with an abiotic origin. Aliphatic amines (such as methylamine) and carboxylic acids (such as acetic acid) were also detected, likely retained on Ryugu as organic salts.

The presence of aromatic hydrocarbons, including alkylbenzenes, fluoranthene, and pyrene, implies hydrothermal processing on Ryugu’s parent body and/or presolar synthesis in the interstellar medium. Nitrogen-containing heterocyclic compounds were identified as their alkylated homologs, which could have been synthesized from simple aldehydes and ammonia. In situ analysis of a grain surface showed heterogeneous spatial distribution of alkylated homologs of nitrogen- and/or oxygen-containing compounds.

The large number of carbon-based molecules is not unlike data from similar carbonaceous chondrite meteorites, though the differences appear to suggest Ryugu experienced chemical processes in connection with water during its lifetime.

Note for clarity: Organic molecules are not life. This is a term scientists use for any carbon-based molecule.

Scientists pin down Venus’s most likely active volcanic regions

9:40 am

The Aine corona on Venus

Click for original image.

Using archival data from the Magellan radar imaging Venus orbiter from the early 1990s, scientists think they have identified the regions Venus that are most likely to have active volcanoes, places that have a unique Venusian circular feature called coronae.

The researchers focused on 65 previously unstudied coronae that are up to a few hundred miles across. To calculate the thickness of the lithosphere surrounding them, they measured the depth of the trenches and ridges around each corona. What they found is that ridges are spaced more closely together in areas where the lithosphere is more flexible, or elastic. By applying a computer model of how an elastic lithosphere bends, they determined that, on average, the lithosphere around each corona is about 7 miles (11 kilometers) thick – much thinner than previous studies suggest. These regions have an estimated heat flow that is greater than Earth’s average, suggesting that coronae are geologically active.

Thus, more volcanic activity, releasing the planet’s interior heat outward.

This research confirms other work done looking at coronae back in 2020.

ULA now targets May 4th for first Vulcan launch

9:23 am

According to ULA’s CEO, the company has now scheduled the first launch of its Vulcan rocket for May 4, 2023, a delay of about a month from the previous schedule.

The delay to the new date was caused by a variety of factors. First, the launch window for the prime payload, Astrobotic’s Peregrine lunar lander, is only open certain days of the month. Second, that lander is just finishing final testing, and the extra time was needed to get it to Cape Canaveral and stacked on the rocket. Third, the extra time was needed to complete all the dress rehearsal countdown tests prior to launch. However, the biggest reason for the delay appears to have been one of Blue Origin’s BE-4 rocket engines.

ULA and Blue Origin are finishing the formal qualification of the BE-4 engine, which Bruno described as the “pacing item” for the launch. “It’s taking a little bit longer than anticipated.”

He revealed that, in a qualification test of one of two engines, the liquid oxygen pump had about 5% higher performance than expected or seen on other engines. “When the performance of your hardware has even a small shift that you didn’t expect, sometimes that is telling us that there could be something else going on in the system that is potentially of greater concern.”

ULA and Blue Origin decided to take the engine off the test stand and disassemble it. Engineers concluded that the higher performance was just “unit-to-unit variation” and not a problem with the engine itself, Bruno said.

If Blue Origin was manufacturing and testing these engines as it needs to do, in large numbers, it would have known a long time ago the range of “unit-to-unit variation” in performance. That this is not known at this late time once again tells us that the company is still struggling to build these engines routinely. Yet it will soon need to produce plenty in short order in order to sustain not only ULA’s Vulcan launch schedule but the launch schedule of its own New Glenn rocket.

China places classified satellite into orbit using Long March 2C rocket

9:12 am

From one of its interior spaceports China today successfully launched a classified “remote sensing” satellite using its Long March 2C rocket.

No information about the payload was released by China, not even a satellite name. Nor was there any word on whether the expendable first stage landed near habitable areas.

The 2023 launch race:

12 SpaceX
7 China
3 Russia
1 Rocket Lab
1 Japan

Ingenuity completes 45th flight; Perservance races to keep up

6:48 pm

Overview map
Click for interactive map.

On February 22, 2023, the Mars helicopter Ingenuity completed its 45th flight on Mars, flying 1,627 feet in 2 minutes and 24 seconds. This was 13 feet farther than planned, and 5 seconds longer, the extra distance likely because the helicopter needed to find a good landing spot.

The green dot on the map to the right indicates Ingenuity’s new position. The blue dot marks Perseverance’s position. The rover has been moving fast, quickly climbing up onto the delta behind Ingenuity only days after it has completed each recent flight. It appears the Perseverance science team wishes to reach the top of the delta as fast as possible, where it can then begin drilling for more core samples.

It is becoming increasing clear the limitations of Perseverance. It was designed to obtain these core samples for return to Earth, but in the process many of the geological tools and sensors that Curiosity carries were eliminated. The result is the Perseverance can’t actually find out as much about the geology in Jezero Crater as Curiosity can. This doesn’t mean it can’t do any geological work, because it certainly can, but all of the analysis of drill samples that Curiosity does is beyond Perservance’s capabilities. It basically can only do contact science and close inspection. The analysis of its drilled samples must wait until the samples are returned to Earth, about a decade from now.

Russians launch unmanned Soyuz to ISS

5:34 pm

The Russians today successfully launched an unmanned Soyuz capsule to ISS to replace the capsule damaged by a coolant leak in December.

The new capsule will dock to ISS in two days, on February 25th. Then on February 27th a Falcon 9 rocket will launch four astronauts on its Endurance reusable Dragon capsule. The damaged Soyuz capsule will be de-orbited shortly thereafter.

Because of the new Soyuz was intended to remain in orbit with its crew until September, Roscosmos and NASA agreed to keep the crew from the damaged Soyuz on ISS until then, making the mission of these two Russians and American Frank Rubio about a year long. There is a chance Rubio could set a new record for the longest American mission, depending on the exact day his mission returns.

The 2023 launch race:

12 SpaceX
6 China

American private enterprise still leads China 13 to 6 in the national rankings, and the entire world combined 13 to 11. SpaceX alone still leads the entire world 12 to 11.
