China’s possible plans for expanding Tiangong-3

9:20 am

Though the plans have apparently not been approved, the designers of China’s Tiangong-3 space station are now considering expanding the station with additional large modules.

“Following our current design, we can continue to launch an extension module to dock with the forward section of the space station, and the extension module can carry a new hub for docking with the subsequent space vehicles,” [Wang Xiang, commander of the space station system at the China Academy of Space Technology (CAST)] told CCTV following the return to Earth of the Shenzhou-14 crew Dec. 4.

With a new docking hub, the Chinese would actually have the potential of doubling the station’s size by duplicating its present configuration with one central module (with the hub) and two side modules.

The station’s design, an upgrade of the Soviet Union’s Mir station, also allows for relatively easy replacement of modules as they age. Though the station only has a planned ten-year life, do not be surprised if it remains operational for many decades beyond that.

New gamma ray burst violates the explanations of scientists

9:04 am

The uncertainty of science: A newly discovered long gamma ray burst (GRB) that appears to have been formed by the merger of two neutron stars has contradicted the long held views of scientists as to the origin of this particular type of GRB.

Prior to the discovery of this burst, astronomers mostly thought that there were just two ways to produce a GRB. The collapse of a massive star just before it explodes in a supernova could make a long gamma-ray burst, lasting more than two seconds. Or a pair of dense stellar corpses called neutron stars could collide, merge and form a new black hole, releasing a short gamma-ray burst of two seconds or less.

But there had been some outliers. A surprisingly short GRB in 2020 seemed to come from a massive star’s implosion (SN: 8/2/21). And some long-duration GRBs dating back to 2006 lacked a supernova after the fact, raising questions about their origins. “We always knew there was an overlap,” says astrophysicist Chryssa Kouveliotou of George Washington University in Washington, D.C., who wrote the 1993 paper that introduced the two GRB categories, but was not involved in the new work. “There were some outliers which we did not know how to interpret.”

There’s no such mystery about GRB 211211A: The burst lasted more than 50 seconds and was clearly accompanied by a kilonova, the characteristic glow of new elements being forged after a neutron star smashup.

Kouveliotou’s claim is not how I remember things back in 1990s. Then, the astronomers seemed certain that the two GRB classes were entirely separate, with no overlap, despite the large number of uncertainties.

Sweden upgrading suborbital launchsite for orbital business

8:52 am

A Swedish launchsite that the European Space Agency (ESA) has used on and off for decades for suborbital test launches is now being upgraded to make it attractive to smallsat rocket companies.

Founded by the European Space Agency (ESA) in 1966 to study the atmosphere and Northern Lights phenomenon, the Esrange space center has invested heavily in its facilities in recent years to be able to send satellites into space.

At a huge new hangar big enough to house two 30-meter rockets currently under assembly elsewhere, Philip Pahlsson, head of the “New Esrange” project, pulls up a heavy blue door. Under the rosy twilight of this early afternoon, construction machines nearby can be seen busily completing work on three new launch pads. “Satellite launches will start to take place from here next year,” Pahlsson says.

In Europe, Esrange is competing with a new Norway spaceport for the first orbital rocket launch. It is also competing with two spaceports in Scotland. And the one that makes launches easy for the new smallsat rocket companies is going to garner the most business.

UK regulators block Virgin Orbit launch

8:42 am

We’re here to help you: Bureaucrats at the United Kingdom’s Civil Aviation Authority (CAA) have refused to issue Virgin Orbit a launch permit in time for its proposed December 14, 2022 launch date, and have thus forced the company to stand down.

Dan Hart, Virgin Orbit chief executive, said the Civil Aviation Authority’s refusal to give the company an operating licence meant the launch would be delayed again. Britain’s first ever space mission was scheduled to take place on the night of December 14, Virgin Orbit announced yesterday.

But Virgin Orbit was forced to row back on its plans within hours. The company will now “retarget launch for the coming weeks”.

The refusal does not mean that the launch will never happen, only that the CAA is not going to hurry its approval for Richard Branson. This delay is thus crushing this company, as it has been unable to launch other customers while this launch is pending, and therefore has been unable to earn any additional revenue.

That the CAA has been working on this permit for more than half a year and still cannot issue, however, does not bode well for future UK rocket launches. Virgin Orbit launches from a runway, using a 747, and has done so successfully four times already. If the CAA cannot figure out how to okay it to launch after doing six months of paperwork, how is it going to okay launches for regular rockets from the two Scotland launchpads now under construction? Based on this situation, it will take forever to get launches off, and thus the CAA is likely going to force satellite customers top migrate to other spaceports outside the UK.

A Martian ship’s prow

A Martian ship's prow
Click for full image.

Cool image time! The photo to the right, cropped, reduced, and sharpened to post here, was taken on August 31, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists call “layering” surrounding this pointed mesa, which I roughly estimate to be somewhere between 200 to 400 feet high.

As you approach the mesa you first walk on the dust-covered flat plains. Then you start up a slope of what looks like alluvial fill, material that over time has fallen from the mesa to pile up as an apron at its base. You then reach a series of terraces, each likely marking a different layering major event from sometime in the distance past. Over time, for unknown reasons, the material surrounding this material has eroded away, while the mesa and its layers somehow survived.

The overview map below helps tell us what those past layering events were, as well as the source of the large amount of dust and sand at this location.

Pushback: Judge rules flight attendant must be rehired by Southwest, but reduces her award significantly

1:52 pm

Southwest Airlines: Enemy to free speech

Blacklists are back and the business community loves ’em: Though Charlene Carter, the Southwest flight attendant who was fired because she expressed opinions the company and her union did not like, had won her lawsuit against the company, federal district Judge Brantley Starr has reduced the jury award to her from $5.1 million to $810,000 in order “to comply with federal limits on punitive damages.”

The judge this week reduced that award to $300,000 in compensatory and punitive damages from Southwest and $300,000 from the union, $150,000 in back pay and about $60,000 in interest.

In ordering Southwest to reinstate Carter this week, the judge made a reference to a line in Southwest advertising campaigns. “Bags fly free with Southwest. But free speech didn’t fly at all with Southwest in this case,” Starr wrote.

This story is an update on two previous blacklist columns, the second of which described the ugly email correspondence between company and union officials prior to Carter’s firing. Brian Talburt, an official with the Transit Workers Union (TWU), had written to both his boss, union head Audrey Stone, as well as one Southwest manager as follows about Carter:

Blue Origin-led team bids for NASA manned lunar lander contract

11:09 am

Capitalism in space: Though few details have been released, Blue Origin has teamed up with Boeing and Lockheed Martin to bid for a NASA contract to build a second manned lunar lander, after SpaceX’s Starship.

Blue Origin revealed its team’s submission to that second NASA program in a brief statement posted on its website on Tuesday, saying “in partnership with NASA, this team will achieve sustained presence on the Moon.”

The deadline for proposals was Tuesday. NASA is expected to make an award decision in June 2023.

Blue Origin’s team also includes spacecraft software firm Draper, Pittsburgh, Pennsylvania-based Astrobotic and Honeybee Robotics, a manufacturer of military and civil robotic systems that was acquired by Blue Origin in January.

It will be interesting to see if this proposed lander is significantly different than the previous proposal, which NASA considered overpriced and not as capable as Starship.

Virgin Orbit schedules launch from the UK, despite no permit

11:01 am

Virgin Orbit has now scheduled its first launch from a Cornwall airport for December 14, 2022, even though the company has not been issued its launch permit from the Civil Aviation Authority (CAA) of the United Kingdom, even after almost six months of delays.

Spaceport Cornwall was awarded an operators licence by the Civil Aviation Authority (CAA) last month, meaning the site is licensed for launch operations.

However, Virgin Orbit as the operator needs both launch and range licences from the CAA before the historic launch can happen. Spaceport Cornwall told MailOnline that December 14 is when the window opens for the first launch attempt – although this is ‘by no means a guaranteed flight date’.

According to a BBC report, that license has still not been issued. I suspect Virgin Orbit has set this date to pressure the CAA to finally get its act together and issue the permit.

China’s Kuaizhou-11 rocket launches test satellite

10:53 am

China today successfully launched what it labeled as a communications test satellite using its smallsat mobile Kuaizhou-11 rocket.

China’s state run press gave little details, other than saying, “The satellite will be mainly used for communications test and key technologies verification of the VDES and the automatic identification system (AIS),” whatever that means.

The leaders in the 2022 launch race:

55 China
54 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 78 to 55 in the national rankings, though it trails the entire world combined 86 to 78.

Computer modelers predict millions will die if China relaxes its zero COVID lockdowns policy

10:45 am

Chicken Little rules again! Scientists, using the same kind of faulty computer models that falsely predicted millions would die in 2020 if we didn’t social distance, wear masks, and shut down all of society (while canceling the Bill of Rights), now predict millions will die in China if that country’s totalitarian communist government relaxes its zero COVID lockdowns policy.

A study based on vaccination rates in March, published in Nature Medicine in May, found that lifting zero-COVID restrictions at that point could “generate a tsunami of COVID-19 cases” over a 6-month period, with 112 million symptomatic cases, 2.7 million intensive care unit (ICU) admissions, and 1.6 million deaths. Peak demand for ICU beds would hit 1 million, more than 15 times the current capacity.

The unvaccinated would account for 77% of the fatalities, according to the authors, primarily at Fudan University. Boosting vaccination rates could slash the toll, but China’s elderly population has remained wary of vaccination. Even today, only 66% of those ages 80 and older have received two doses—versus 90% of the population as a whole—and just 40% have taken boosters.

We of course should trust these scientists without question. How could they possibly be wrong? Bless their hearts. They would never produce junk models simply to promote government overreach and abuse of power.

Ingenuity sets altitude record on 35th flight

10:33 am

Overview map
Click for interactive map.

On December 3, 2022 Ingenuity completed its 35th flight, traveling about 49 feet sideways but reaching a new altitude record for the Mars helicopter of 46 feet.

The map to the right shows the helicopter’s new position by the green dot, with Perseverance’s present position shown with the blue dot. The helicopter only moved slightly to the northwest of its previous position.

The plan had been to test the helicopter’s upgraded software at this new altitude while flying fly 50 feet sideways for 52 seconds at a speed of 6.7 feet per second. The flight met these goals almost exactly, going a distance only slightly shorter, well within its margin of error. The new altitude record however is significant, as going even slight distances higher in Mars’ very thin atmosphere (1/1000th of Earth’s) is challenging, to say the least. This higher flight means Ingenuity can fly up above higher terrain, such as the delta that is Perseverance’s next goal.

InSight’s low power levels holding steady

10:11 am

InSight's power levels as of November 29, 2022

The science team for the Mars’ lander InSight today (December 6th) released a new update (dated November 29th) of the power levels being produced by its dust-covered solar panels.

As of Nov. 29, 2022, InSight is generating an average between 290 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).

I have added this new data unto the graph to the right, though I am puzzled by the date given to the update. Why post this today, when this update covers data only two days after the previous update (November 27th), and is more than a week out of date? This is especially puzzling because the numbers did not change at all.

Nonetheless, the lander is still alive, but barely. One wonders however what happened in the past week, since today’s update does not bring us up to date.

Today’s blacklisted American: Richmond restaurant to the Family Foundation: “No Christians served here!”

2:14 pm

Metzger's: in favor of discrimination

They’re coming for you next: The restaurant, Metzger’s Bar and Butchery in Richmond, Virginia, has now decided that it will no longer serve Christian-affiliated organizations.

Last week The Family Foundation, which is affiliated with the Christian ministry Focus on the Family, had scheduled a gathering at Metzger’s. However, ninety minutes before the event was to take place, Metzger’s told the foundation that it would not serve them, and the event was cancelled. In the restaurant’s own words:

“We refused service to a group that had booked an event with us after the owners of Metzger found out it was a group of donors to a political organization that seeks to deprive women and LGBTQ+ person of their basic human rights in Virginia,” they wrote. “We have always refused service to anyone for making our staff uncomfortable or unsafe and this was the driving force behind our decision.

“Many of our staff are women and/or members of the LGBTQ+ community,” the community wrote. ‘All of our staff are people with rights who deserve dignity and a safe work environment.” [emphasis mine]

So in other words, Metzger’s has now posted a sign on its door, stating bluntly “No religious individuals served here!”

NOAA gives Maxar permission to photograph things in space

1:39 pm

We’re here to help you! According to a Maxar press release today, it has obtained permission from the federal agency NOAA (initially created to study the weather) to use the company’s satellites to not only photograph things on Earth but things in space as well.

Maxar Technologies (NYSE:MAXR) (TSX:MAXR), provider of comprehensive space solutions and secure, precise, geospatial intelligence, today announced that the National Oceanic and Atmospheric Administration (NOAA) has modified Maxar’s remote sensing license to enable the non-Earth imaging (NEI) capability for its current constellation on orbit as well as its next-generation WorldView Legion satellites.

Through this new license authority, Maxar can collect and distribute images of space objects across the Low Earth Orbit (LEO)—the area ranging from 200 kilometers up to 1,000 kilometers in altitude—to both government and commercial customers. Maxar’s constellation is capable of imaging objects at less than 6 inch resolution at these altitudes, and it can also support tracking of objects across a much wider volume of space.

This new permit apparently will allow Maxar’s satellites to not only look down at the Earth, but look around and image other orbiting objects, for both the military and commercial customers.

My question however is this: By what legal authority does NOAA claim the right to regulate such activity? I can see none at all, yet like other regulatory agencies (such as the FCC) during this Biden administration, NOAA is grasping this illegal power, and companies like Maxar have decided it is better to go along to get along.

During the Trump administration NOAA tried to claim, without any legal authority, that it had the right to regulate all photography in space, and thus actually forced SpaceX during one Falcon 9 launch to cease public release of the imagery from its rocket.

Within three weeks Trump’s Commerce secretary, Wilbur Ross, stepped in bluntly to block NOAA’s power grab. As he said publicly, “This is silly and it will stop,”

Trump is gone however and the Biden administration is all in with letting government agencies expand their power. Though NOAA might have a some regulatory responsibility related to remote sensing in space, under no conditions can I see that responsibility giving it the right to tell any private American citizen or company what they can or cannot photograph.

I am of course assuming the first amendment to the Constitution is still in force. In today’s America it might not be.

Martian dunes, as far as the eye can see

Martian dunes

Cool image time! The photo to the right, cropped, reduced, and sharpened to post here, was taken on July 14, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the dune filled floor of an unnamed 25-mile-wide ancient and very eroded Martian crater.

These endless dunes — which extend far beyond this photo to cover the entire floor of this crater as well as an overlapping crater to the north that is only slightly smaller — reveal something fundamental about this location: The winds prevail from one direction consistently, from either the north or the south. Closer inspection would likely resolve which way, but I don’t have the knowledge or access to the data to do so.

Ukrainian rocket startup targets ’23 for first launch

8:57 am

The new colonial movement: A Ukrainian rocket startup, Promin Aerospace, now expects to complete the first suborbital launch of a test rocket in 2023, despite the Russian invasion and its regular bombing the city of Dnipro, where the company is based.

On Feb. 22, two days before the Russian invasion, Rudominski sent the first batch of emails seeking seed investment. When the war started, Promin executives realized their investment plans would need to be put on hold while their focus shifted to the safety of employees, families and friends, plus support for Ukrainian defense and humanitarian relief efforts.

By early April, most employees were back working full time.

The company does not reveal its location out of fear of further Russian bombing.

As for its planned rocket launch, though it wishes to do the test from the Ukraine, it also has a deal with one of the new spaceports in Scotland and could launch from there if necessary.

Orion completes burn to send spacecraft back to Earth

8:50 am

NASA’s Orion capsule yesterday successfully fired its engines as it zipped past the Moon to send it on a trajectory back to Earth, with splashdown in the Pacific off the coast of California scheduled for December 11, 2022.

Not all was hunky-dory, however. Prior to the burn a power unit shut down unexpectedly.

A power unit on board the Orion spacecraft turned off four devices “responsible for downstream power” that connect to the Artemis 1 vehicle’s propulsion and heating subsystems, NASA officials wrote in a statement. But mission personnel swiftly put a fix in place and the mission is carrying on, the statement emphasized. “Teams confirmed the system was healthy and successfully repowered the downstream components,” agency officials wrote in the statement, released late on Sunday. “There was no interruption of power to any critical systems, and there were no adverse effects to Orion’s navigation or communication.”

Engineers think the shut down was related to a test performed in connection with an earlier incident.

Regardless, all now appears well for that December 11nd splashdown.

Today’s blacklisted American: Pernicious anti-white bigotry controls the government in Seattle

1:15 pm

Seattle: dedicated to segregation!
Seattle, controlled by Democrats and dedicated to the new segregation!

“Segregation today, segregation tomorrow, segregation forever!” Because of the continuous and never-ending racial bigotry that is now normal in Seattle and which eventually forced him from his city job, Joshua Diemert has sued for $300,000 in compensatory and punitive damages.

You can read the lawsuit here [pdf].

The list of abuses against Diemert is beyond horrible. Simply because he is white he was forced to resign a supervisor position so that two unqualified minorities could replace him, was then denied later promotions, then investigated for no reason, and was later accused of being a genocidal Nazi while being forced to attend critical race theory classes that routinely labeled all whites as bigots. As only one small example, consider these details from his complaint:

The steep interior rim of Aristarchus Crater

Aristarchus Crater
Click for larger image.

Cool image time! The photo to the right, cropped, reduced, and sharpened to post here, is a just released image taken by Lunar Reconnaissance Orbiter, looking across the top of Aristarchus Crater on the Moon from a height of only 60 miles, with the dark surrounding plateau in the foreground contrasting sharply with the bright crater interior. For scale, the distance from the floor of the crater to the top of the rim is about 9,000 feet. The bright central peak is about 1,300 feet tall. The contrast in brightness inside and outside the crater is explained thus:

Adjacent to Aristarchus crater is the Aristarchus plateau, one of the largest volcanic centers on the Moon. Here we find one of the largest rilles [on the Moon, dubbed Vallis Schröteri], a massive pyroclastic deposit, and the source of extensive flood basalts.

These volcanic materials are considered relatively young (for the Moon) – 1.5 to 2.5 billion years. The pyroclastic deposit formed when magma was explosively ejected from the vent and broke into small droplets quenched as glass in the cold vacuum of space as they fell back to the surface. Due to their high glass content, the pyroclastic deposits are distinctly low in albedo (relatively dark), providing a dark background for the bright Aristarchus crater. Within the crater, some of these pyroclastic deposits may be visible as the darkest areas on the far wall, and glassy impact melt is moderately lower in reflectance than the bright, rocky materials exposed on areas of the crater floor and walls.

The overview map below shows both the crater and the vent from which Vallis Schröteri belched.

Overview map
Click for interactive map.

The panorama above, created from 31 images taken by Curiosity’s right navigation camera on December 5, 2022, provides us a wonderful overview of the rover’s recent and future travels amid the lower foothills of Mount Sharp in Gale Crater.

The overview map to the right provides context. The blue dot indicates Curiosity’s present position. The yellow lines indicate the approximate area viewed by the panorama. The red dotted line indicates Curiosity’s planned route, with the white dots the route it has actually traveled. On the panorama, the pink dotted line indicates where it has been, and the red dotted line where it is going.

For scale, Kukenan is estimated to be about 1,500 feet high. Though Chenapua in front seems comparable, it is actually much smaller, only about 200 to 300 feet high, at the most. Orinoco, though lower on the mountain, is probably about 300 to 400 feet high.

To really see the magnificence of this terrain, you must click on the panorama and explore the full image. Curiosity is truly traveling amid mountains, and is the first human robot to do so on another world.

The uncertainties surrounding India’s proposed first manned mission

10:00 am

Link here. The article does a nice job of outlining the program, dubbed Gaganyaan, as well as the many issues that has caused the first launch to be delayed more than three years.

The key quote however is this:

Despite the government claiming that there would be no delays due to Covid, the first uncrewed flight was rescheduled from 2020 to 2021 and then again to 2022. The dates were once again revised to late 2023 or early 2024, announced Union minister of state for science and technology Jitendra Singh in September this year. [emphasis mine]

The highlighted claim is quite amusing, considering how India’s government space agency ISRO shut down entirely because of the Wuhan panic for more than two years, and remains somewhat dormant even now. As a result of that panic, ISRO lost almost its entire commercial market to American companies.

Read the entire article. It summarizes the state of Gaganyaan in good detail, which also implies that a first launch in ’24 remains questionable.

Pushback: Kroger must pay $180K to two Arkansas workers, fired for refusing to support the queer agenda

1:14 pm

Kroger's rainbow heart apron

Bring a gun to a knife fight: To settle a lawsuit Kroeger has agreed to pay $180K to two Arkansas workers whom the company had fired when both asked to be excused from wearing company aprons that included a rainbow heart that they believed endorsed the queer agenda.

Workers at the store got the new uniforms in April 2019 that included a rainbow heart embroidered on the top left portion of the bib, according to court documents. Both of the workers believe the “literal interpretation of the Bible,” held “religious belief that homosexuality is a sin” and “sincerely believed the apron violated (their) religious beliefs,” according to the lawsuit.

One employee asked to wear their nametag over the logo. Another asked for a different apron. Both employees were fired within two months.

The image to the right shows an apron with this rainbow heart. While some suggest this heart has nothing to do with promoting homosexual rights, the company’s strong advocacy of the queer agenda says otherwise. From Kroger’s own website:

Martian glaciers below 30 degrees latitude

A Martian glacier below 30 degrees north latitude
Click for full image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 28, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). While it shows what looks like a somewhat typical Martian glacial flow pushing through a gap between hills, this glacial flow is not typical. It sits at just under 30 degrees north latitude, closer to the equator than almost any glacial feature on Mars. Moreover, the younger impact crater on top suggests this glacier has been here for some time. Though the impact is younger than the crater, it is not that young, as the dark streaks normally seen in the first years after impact are gone.

Thus, this glacier suggests that not only can near surface Martian ice exist closer than 30 degrees latitude from the equator, it can survive there for a considerable amount of time.

Nor is this glacial flow, so close to the equator, unusual for this region of Mars.
