The son of one of the co-founders of Hamas tells it like it is

2:13 pm

Rather than write another long essay detailing (based on facts) the evil and genocidal nature of Hamas in Gaza, I think it better today to let Mosab Hassan Yousef, the oldest son of Hamas co-founder Sheikh Hassan Yousef, do the speaking. An interview of him by Sky News Australia conducted yesterday is embedded below.

His passionate horror of Hamas — from long very personal experience — is evident and clear. So is his intellectual honesty. He will not lie to himself for the sake of alliance, ethnicity, religion, or anything. All that matters is the truth, which he states very bluntly.

“This is my message: an ex-Hamas member, as a son of one of Hamas’ founders, enough of this. If we don’t stop them now, the next war is going to be deadlier and only God knows what will happen next if Hamas is not finished as soon as possible,” Mr Yousef said.

“They opened the gates of hell on the Palestinian people.

“They are willing to actually sacrifice many Palestinian children, the entire Palestinian people and use them as fuel to … achieve their ideological agendas, their religious agendas.”

To underline the truth of his words, for his own protection Yousef now lives in the United States, his location was kept secret, and he refused to answer any personal questions about his specific plans. He knows better than anyone that Hamas will kill him if it can. It is a organization of violence, hate, and murder. Defy it, no matter who you are, and it will have no mercy upon you.

For such an organization civilized people should exhibit no mercy. It must be treated as the Nazis were treated in World War II. It must be obliterated, no matter the cost.

Giant airship gets clearance for test flights

10:45 am

A giant rigid-frame balloon airship, dubbed Pathfinder-1 and reminiscent of the airships from the early 20th century, has gotten clearance to begin flight tests at Moffett Field in California.

At 407 ft (124 m) long and 66 ft (20 m) in diameter, it’s considerably longer than the “flying buttocks” of the Airlander 10, although less than half of its width. It might not qualify as the world’s largest aircraft, but it’s still absolutely enormous, approaching twice the length of an Airbus A380.

…Currently housed in a monstrous hangar in Mountain View, California, Pathfinder 1 has already flown indoors earlier this year. According to IEEE Spectrum, the company has now been awarded the special airworthiness certificate required to fly this beast outdoors – at less than 1,500 ft (460 m) of altitude, and within the boundaries of Moffett Field and the neighboring Palo Alto Airport’s airspace.

Because of the lightweight materials being used, Pathfinder-1 will use helium, not hydrogen, to lift it. The hope is that this airship can be used to transport cargo. The project is financed by Google co-founder Sergey Brin.

Is a recently discovered near Earth asteroid a piece from the Moon?

10:38 am

The uncertainty of science: Researchers now think they have enough information to claim that a recently discovered near Earth asteroid, dubbed Kamo`oalewa, could actually be a piece of the Moon, flung from it during a asteroid impact in the past few million years.

The 2021 study found that Kamo`oalewa’s spectrum was unlike that of other near-Earth asteroids but matched most closely that of the moon. Based on this, the team hypothesized that the asteroid could have been ejected from the lunar surface as a result of a meteoroidal impact.

In the new study, Malhotra and her team wanted to determine the feasibility for a knocked-off piece of the moon to get into this quasi-satellite orbit – a phenomenon that is quite unlikely, Malhotra said. Moon fragments that have enough kinetic energy to escape the Earth-moon system also have too much energy to land in the Earth-like orbits of quasi-satellites, she said.

With numerical simulations that accurately account for the gravitational forces of all the solar system’s planets, Malhotra’s group found that some lucky lunar fragments could actually find their way to such orbits. Kamo`oalewa could be one of those fragments created during an impact on the moon in the past few million years, according to the study.

The scientists add that the asteroid’s solar orbit, which keeps its flying in relative formation with the Earth for millions of years, strengthens this hypothesis.

It must be noted that this remains an unconfirmed hypothesis. A spacecraft would have to visit Kamo’oalewa and obtain samples to study to confirm it.

UK awards German launch startup Rocket Factory Augsburg $4.3 million for first launch

10:32 am

The United Kingdom has given a $4.3 development grant to the German launch startup Rocket Factory Augsburg (RFA) to pay for launch preparations at the Saxavord spaceport in the Shetland Islands.

The real news from this article however is the continuing delays for anyone to launch from Great Britain. Previously the two Scottish spaceports, one in Shetland and the other in Sutherland, had anticipated the first launches in 2023, from the three companies RFA, Orbex, and ABL. Now it appears that those launches could be delayed into the middle of 2024.

RFA currently expects to launch its three-stage, 30-meter-tall RFA One rocket at some point during the three months to the end of June, recently delayed from the end of this year.

…ABL had planned to conduct its SaxaVord Spaceport launch in 2023, but has yet to announce a date for its next launch attempt anywhere after its inaugural mission from Alaska failed to reach orbit Jan. 10.

ABL is gearing up for its second launch attempt, hopefully before the end of this year, but it will do it from the Kodiak spaceport in Alaska.

One can’t help wondering if these delays are connected the red tape from UK’s Civil Aviation Authority (CAA), which delayed issuing a launch licence to Virgin Orbit so long it literally helped bankrupt the company. For example, Orbex applied for its launch license from Sutherland in January 2022, and 22 months later it apparently has still not gotten an approval from the CAA.

This grant from the UK government might be that government’s effort to keep RFA — faced with CAA delays — from switching its launch site out of Great Britain.

Russia’s Soyuz-2 rocket launches military satellite

9:40 am

Russia today used its Soyuz-2 rocket to launch a classified military surveillance satellite, lifting off from its Plesetsk spacesport in northern Russia.

A graphic at the link shows the rocket’s flight path crossed over almost all of Russia as it flew east, with its lower stages and fairings crashing on land. Though the drop zones were inside Russia, there are very isolated regions in the high Arctic latitudes, with few inhabited areas.

The leaders in the 2023 launch race:

76 SpaceX
48 China
14 Russia
7 Rocket Lab
7 India

American private enterprise still leads China 88 to 48 in successful launches, and the entire world combined 88 to 77. SpaceX by itself now trails with the rest of the world (excluding American companies) 76 to 77.

Pushback: Fired director of college’s Diversity, Equity, and Inclusion department accuses movement of promoting bigotry

2:31 pm

Tabia Lee
Tabia Lee, fighter for freedom and a
color-blind society

They’re coming for you next: Tabia Lee, a black woman who was fired as faculty director for the Office of Equity, Social Justice, and Education [OESE] at De Anza College in California has, as promised, refused to go quietly.

As I reported in March, Lee was fired because she took the word “inclusion” literally, trying to establish a color-blind policy that would provide some aid and comfort to the Jewish students on campus who were experiencing almost daily incidents of harassment and bigotry, simply because they were Jewish.

Her reward? She was herself harassed, with some calling her a “dirty Zionist,” then denied tenure, then fired.

Since then she has not gone quietly into that good night. In July Lee suited De Anza College, as well as ten specific school officials, charging the school violated her First Amendment rights, California’s Constitution, and its Common Law in censoring and firing her.

Her name came up again this week because she wrote a blistering op-ed for the New York Post, blasting not only De Anza for its racist DEI policies, but blasting the entire “Diversity, Equity, and Inclusion” movement as nothing more that a Nazi-like movement promoting bigotry and hate.

The icy terrain near one of Starship’s prime candidate landing spots on Mars

The icy terrain near Starship's prime landing spot on Mars
Click for original image.

Cool image time! The picture to the right, cropped to post here, was taken on August 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The camera team labeled the picture a “terrain sample,” which generally means it was not taken as part of any scientist’s specific research request, but to fill a gap in the schedule so as to maintain the camera’s proper temperature. When the team needs to do this, they try to pick a location in the gap that might have some interesting features. Sometimes such pictures show relatively boring features. Sometimes the results are fascinating.

In this case the location chosen was in the northern lowland plains of Mars, in a region called Amazonis Planitia. At 38 degrees north latitude it is not surprising that the photo shows ice features. All the depressions here appear to have an eroding glacier, while the surrounding plateau resembles an untouched snow field in the very early spring, the snow beginning to sublimate away to leave the top rough and stuccoed. Note too that these depressions are likely not impact craters (they have no upraised rims and many are distorted in shape), but were likely formed by that same sublimation process.

New data better maps the supernova remnant SN1006

10:50 am

SN1006, as seen in X-rays
Click for original image.

Using data from both the Chandra X-ray Observatory and the Imaging X-ray Polarimetry Explorer (IXPE), scientists have now better mapped the magnetic field and the remnant from the supernova that occurred in 1006 AD.

The false color image to the right shows this data. From the caption:

The red, green, and blue elements reflect low, medium, and high energy X-rays, respectively, as detected by Chandra. The IXPE data, which measure the polarization of the X-ray light, is show in purple in the upper left corner, with the addition of lines representing the outward movement of the remnant’s magnetic field.

From the press release:

Researchers say the results demonstrate a connection between the magnetic fields and the remnant’s high-energy particle outflow. The magnetic fields in SN 1006’s shell are somewhat disorganized, per IXPE’s findings, yet still have a preferred orientation. As the shock wave from the original explosion passes through the surrounding gas, the magnetic fields become aligned with the shock wave’s motion. Charged particles are trapped by the magnetic fields around the original point of the blast, where they quickly receive bursts of acceleration. Those speeding high-energy particles, in turn, transfer energy to keep the magnetic fields strong and turbulent.

At present scientists really do not understand the behavior of stellar-sized magnetic fields. It is very complex, involving three dimensional movements that are hard to measure, as well as electromagnetic processes that are not well understood. While this new data doesn’t provide an explanation, it does tell us better what is actually happening. The theories will follow.

Australia and the U.S. agree to facilitate rocket launches in Australia

10:37 am

A technology agreement announced on October 25, 2023 between Australia and the U.S. included language that will allow for American rocket companies to launch from Australia, as well as Australian rocket companies to launch American satellites.

According to the White House statement, the agreement…

…provides the legal and technical framework for U.S. commercial space launch vehicles to launch from Australia in a manner that: protects sensitive U.S. launch technology and data in Australia consistent with our shared nonproliferation goals; and creates the potential for new space-related commercial opportunities.

A private Australian spaceport, Equatorial Launch Australia (ELA), has been working to bring U.S. launches there. In addition, an Australian rocket startup, Gilmour Space, wants to launch American payloads. This new government agreement is supposed to facilitate both.

Rocket Lab expects to resume Electron launches before end of year

10:26 am

Following September 2023 launch failure of its Electron rocket, Rocket Lab now says it has obtained a launch approval from the FAA, and expects to resume Electron launches before end of year.

In the company’s October 25, 2023 press release, it stated the following:

The FAA, the federal licensing body for U.S. launch vehicles, has now confirmed that Rocket Lab’s launch license remains active, which is the first step to enable launches to resume. Rocket Lab is now finalizing a meticulous review into the anomaly’s root cause, a process that involves working through an extensive fault tree to exhaust all potential causes for the anomaly, as well as completing a comprehensive test campaign to recreate the issue on the ground. The FAA is providing oversight of Rocket Lab’s mishap investigation to ensure Rocket Lab complies with its FAA-approved mishap investigation plan and other regulatory requirements. In addition, the National Transportation Safety Board (NTSB) was granted official observer status to the investigation. The full review is expected to be completed in the coming weeks, with Rocket Lab currently anticipating a return to flight later this quarter with corrective measures in place.

Though the FAA is apparently not trying to slow things down, this release gives us a hint at how the new so-called streamlined regulations established this year are actually making things harder. These regulations force the FAA to get more involved in making sure the company has done all due diligence, something the FAA really isn’t qualified to do. To meet these demands, companies now apparently have to jump through many new hoops to satisfy the new regulations.

ABL preparing for second launch attempt of its RS1 rocket

10:09 am

ABL's redesigned rocket launch mount
ABL’s redesigned rocket launch mount

Since its first test launch of its RS1 rocket failed in January 2023, ABL has spent the last ten months doing major revisions of the rocket’s launch mount as well as preparing an upgraded new rocket for a second test launch attempt, expected in the coming months.

This information comes from a long update posted by the company’s CEO, Harry O’Hanley on October 25, 2023.

It appears failure occurred because of a fire at the base of the rocket after liftoff, which in turn was caused by the small size of the rocket’s launch mount.

By analyzing video and data, we formulated a leading theory behind the source of the fire. Our hypothesis centered around the Launch Mount, which is the GS0 assembly that raises and lowers the vehicle. It was designed to fit fully assembled inside a shipping container. While this made transport simple, it resulted in the rocket being held close to the ground.

We believe the compact Launch Mount and proximity of RS1 to the ground restricted the flow of engine exhaust gas. This caused plume recirculation and drove pressures and temperatures beneath the rocket to exceed the RS1 base heat shield design capability. The hot combustion gases breached the aft heat shield and initiated the engine compartment fire. We corroborated this theory with a variety of tests and analyses, including multi-species CFD performed both in-house and by an independent partner.

The graphic to the right, rearranged and annotated to post here, shows the new larger mount. Because of the time it has taken to make that launch mount upgrade, the company also decided to fly its next version of RS1 on this second test launch, rather than the backup rocket from the first launch. This upgraded RS1 has 20% more thrust with a detachable engine section that makes access to it much easier.

O’Hanley made no mention of a specific target launch date from the Kodiak spaceport in Alaska, but his post implies the launch is coming very soon.

Russian astronauts locate coolant leak on spacewalk

9:29 am

Coolant leak on Nauka radiator

In an almost eight hour spacewalk yesterday, two Russian astronauts were able to locate the source of the coolant leak on a radiator unit connected to the new Nauka module on the Russian half of ISS.

The image to the right, a screen capture from the live stream, shows the leak location, where a small white droplet sits on one of the coolant lines that connect two radiator panels. You can also see darkening on the tubes to either side, likely also caused by the leaking ammonia. To locate it ground controllers opened valves to let coolant into the line while the astronauts watched for changes, and were able to see the coolant come out of this spot.

One astronaut also noted the following during the inspection:

[B]efore noticing the growing deposit of liquid coolant, Kononenko reported seeing a myriad of small holes on the surface of the radiator’s panels. “The holes have very even edges, like they’ve been drilled through,” Kononenko radioed to the flight controllers working in Moscow Mission Control. “There are lots of them. They are spread in a chaotic manner.”

In the past year similar coolant leaks have occurred on both a Progress freighter and a Soyuz manned capsule, with the leak location in almost the exact same spot, suggesting an intentional cause, not a random micrometeorite hit. This coolant leak in Nauka is on equipment that was launched to ISS in 2010. If it was also drilled, whoever did it did so a long time ago, which implies Russia has a long standing saboteur within its operations.

This conclusion however remains wild speculation. In the dozen-plus years since launch, this radiator has been stored on the outside of ISS, where it could easily have been hit by micrometeorites that would cause those holes and this leak.

The plan is to consider some repair operation on future spacewalks. In the 1980s the Russians did something similar, with astronauts doing six spacewalks to replace a section of fuel line that was leaking on its Salyut-7 station. They cut open its hull and installed a second section of line so that the valves could remove leaking section from operations.

China launches new three-man crew to its Tiangong-3 space station

9:02 am

The new colonial movement: China today successfully used its Long March 2F rocket to place a Shenzhou manned capsule into orbit, carrying a new three-man crew to its Tiangong-3 space station and lifting off from its Jiuquan spaceport in northwest China.

Though relatively little specific information about the crew’s mission has been revealed, it is expected they will do a six month mission, as have previous crews, and conduct spacewalks and maintenance on the station. Meanwhile, the present crew on board will spend about a week transferring duties to the new crew, and then return to Earth after completing its own six-month mission.

No word on where the Long March 2F first stage and its four side boosters crashed in the interior of China, all of which use toxic hypergolic fuels.

The leaders in the 2023 launch race:

76 SpaceX
48 China
13 Russia
7 Rocket Lab
7 India

American private enterprise still leads China 88 to 48 in successful launches, and the entire world combined 88 to 76. SpaceX by itself is now tied at 76 with the rest of the world (excluding American companies).

  • Tiangong-3 solar panel hit by “small space debris”

    • According to this tweet, the damage was “predicted and controllable”, which really tells us nothing. All space stations in orbit experience micrometeorite hits, often very tiny. Anything larger is significant. If this impact was the latter they should release more information.

The hull of Axiom’s first space station module nears completion

1:44 pm

The hull of Axiom’s first space station module is nearing completion, according to officials of the Italian company Thales Alenia Space that is building it.

“The first module shell is effectively completed,” Jason Aspiotis, Axiom’s director of in-space infrastructure and logistics, said at AIAA’s Ascend conference here on Oct. 23. “A lot of the subsystems that will populate the underlying structure–think about life support systems, avionics, propulsion, [guidance, navigation and control systems], power, communications, all that good stuff–we’re developing in a lab in Houston.” Hab One hatches have also been fabricated, tested and prepared for delivery to Thales Alenia Space to support Hab One pressure testing, the company says.

The first module is to be shipped to Houston by 2024 for final assembly and integration at Axiom Space’s factory at Ellington Airport. The company plans to launch the Hab One module in 2026.

Based on this news report, Axiom’s schedule has not experienced any further delays since it pushed back the launch from 2024 in June.

The article also says, almost as an aside, that ISS is planned for decommission “in 2031”, which is one year later than any previous report I’ve seen. I suspect this is correct, but is information that NASA really didn’t want revealed to the public as yet, as it had enough trouble convincing its international European and Japanese partners to stay on until 2030. Moreover, there remains serious concerns the older Russian modules themselves might fail before then, based on the number of stress fractures found in their hulls, so admitting NASA hopes to keep the station flying till ’31 will appear questionable at best.

Swirling galactic-sized streams surrounding a pair of supermassive black holes

Swirling galactic arms surrounding two supermassive black holes

Time for another galactic cool image! The picture to the right, reduced and sharpened to post here, was released today by the Gemini South ground-based telescope in Chile. It shows the streams of gas and stars that swirl around a pair of supermassive black holes at the center of this galaxy, located only 90 million light years away.

The image reveals vast swirling bands of interstellar dust and gas resembling freshly-spun cotton candy as they wrap around the merging cores of the progenitor galaxies. From the aftermath has emerged a scattered mix of active starburst regions and sedentary dust lanes encircling the system.

What is most noteworthy about NGC 7727 is undoubtedly its twin galactic nuclei, each of which houses a supermassive black hole, as confirmed by astronomers using the European Southern Observatory’s Very Large Telescope (VLT). Astronomers now surmise the galaxy originated as a pair of spiral galaxies that became embroiled in a celestial dance about one billion years ago. Stars and nebulae spilled out and were pulled back together at the mercy of the black holes’ gravitational tug-of-war until the irregular tangled knots we see here were created.

The black holes themselves are 154 and 6.3 million solar masses respectively, and are presently about 1,600 light years apart. Scientists calculate that they will merge in about 250 million years. Each once formed the center of its own galaxy. Now both galaxies have merged, creating this three-dimensional whirlpool of arms.

Boeing losses total almost a billion dollars this quarter

1:15 pm

The hits to Boeing keep coming: In addition to the $1.5 billion it has had to write-off because of problems with its Starliner capsule, Boeing is now reporting losses in the third quarter totaling almost a billion dollars, with half those losses coming from overruns on its fixed price contract to provide Air Force One to the U.S. government.

The $482 million loss on the high-profile presidential plane was due to “higher estimated manufacturing costs related to engineering changes, labor instability and the resolution of supplier negotiations,” Boeing Chief Financial Officer Brian West said during the company’s third-quarter earnings call Wednesday.

Boeing has faced numerous problems with the VC-25B program, including shortages of workers and parts, that have delayed delivery of the first of two Air Force One jets until 2027. To date, the company has lost over $2.4 billion on the program, according to a company spokesperson. CEO Dave Calhoun said last year that Boeing should have never agreed to the fixed $3.9 billion price tag.

The second-largest contributor to losses for Boeing’s Defense, Space & Security (BDS) business was a satellite program that cost the company $315 million in the third quarter. The company wouldn’t identify the program, but West said the loss is “tied to customer considerations and higher estimated cost to deliver a highly innovative satellite constellation contract that we signed several years ago.” [emphasis mine]

Let me translate what CEO Calhoun was really saying in the highlighted sentence: “We want a blank check! Boeing is incapable of producing anything based upon a standard fixed price, and wants the federal government to go back to open-ended cost-plus contracts that put no limit to overruns and schedule delays.”

Whether Boeing gets that blank check or not really depends on Boeing. It is very possible our corrupt legislators in Congress — who think money grows on trees — will bring these cost-plus contract back, but I doubt Boeing will win many such contracts in the near future, based on its horrible performance on all levels technically. It needs to completely clean house, with major shake-ups in management and staff, as whoever is working there now is simply doing a terrible job.

Cool image time! The panorama above, enhanced and annotated to post here, was taken on October 21, 2023 by one of the navigation cameras on the Mars rover Perseverance. As shown on the overview map to the right, it looks to the west, at the gap in the rim of Jezero crater, dubbed Neretva Vallis, through which the delta in the crater had once poured.

The blue dot marks the location of Perseverance. The green dot marks the location of Ingenuity, which suggests it is visible within the panorama. I have indicated two features on the panorama that could be the helicopter, but the resolution of this navigation camera image is not good enough to determine with certainty if either is the helicopter or simply a rock.

Beyond the gap can be seen several small mountains, a hint at the generally rough terrain that sits to the west of Jezero that Perseverance will eventually enter and explore. This region is also an area where orbital images suggest a wide variety of minerals, making it a potentially valuable mining location for future Martian settlers.

A dance of three galaxies

10:40 am

Three galaxies merging
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. Though it appears to show two galaxies interacting with each other, other spectroscopic data proves there are actually three large galaxies in the picture. From the caption:

The two clearly defined galaxies are NGC 7733 (smaller, lower right) and NGC 7734 (larger, upper left). The third galaxy is currently referred to as NGC 7733N, and can actually be spotted in this picture if you look carefully at the upper arm of NGC 7733, where there is a visually notable knot-like structure, glowing with a different colour to the arm and obscured by dark dust. This could easily pass as part of NGC 7733, but analysis of the velocities (speed, but also considering direction) involved in the galaxy shows that this knot has a considerable additional redshift, meaning that it is very likely its own entity and not part of NGC 7733.

All three galaxies are quite close to each other, which means they are in the long process of merging together into one larger galaxy.

SpaceX gets ESA contract to launch up to four of its Galileo GPS-type satellites

9:41 am

The European Space Agency (ESA) this week announced that it has awarded SpaceX a launch contract to put up to four of its Galileo GPS-type satellites into orbit. Though the deal is signed, approval must still be obtained by ESA’s members and executive commission.

This will be the first time SpaceX will launch any ESA satellites, and the first time in fifteen years that a Galileo satellite will launch outside of Arianespace operations. Previously the Russians had done a number of Galileo launches, using its Soyuz-2 rocket launching out of Arianespace’s French Guiana spaceport, but that partnership ended with Russia’s invasion of the Ukraine.

For the ESA the situation is even worse. It needs SpaceX to launch its satellites because at present it doesn’t have any of its own rockets to do it. The Ariane-5 is retired, and the new Ariane-6 (meant to replace it) is long delayed, and will not have its first test launch until next year, at the earliest. The Vega-C (too small for Galileo anyway) is also grounded due to design defects in the nozzle of its upper stage, while the Vega rocket it replaces has only one more launch before its own retirement.

Much like the Axiom-UK deal posted below, the American commercial space industry is once again making money from others, solely due to the capabilities developed in the past decade due to competition and freedom.

Axiom signs deal with the United Kingdom to fly all British mission

9:30 am

The space agency of the United Kingdom today announced that it has signed a deal with Axiom to fly an manned mission in space, with four astronauts spending up to two weeks in space (likely in a SpaceX Dragon capsule).

The flight, estimated to cost around £200 million, is being organized in cooperation with the European Space Agency (ESA), though all the astronauts will be British. The announced commander, Tim Peake, spent six months on ISS in 2015, and has come out of retirement to do the flight.

It is also unclear at this moment whether it will fly to ISS, or simply remain in orbit. In fact, few specific details have yet been released.

The bottom line however is that the new American space industry is going to make money from Britain’s desire to be a space power. Seems like a good deal to me.

No Starship/Superheavy launch likely until January?

9:13 am

No Starship test launch until 2024
SpaceX is ready but the federal government says “No!”

We’re from the government and we’re here to help! In describing the effort of Senator Ted Cruz (R-Texas) to help SpaceX prod the federal bureaucracy into approving a new launch license for the company’s Starship/Superheavy rocket, space writer Mark Whittington included this significant but not previously mentioned tidbit that might help us predict when Fish & Wildlife (FWS) might finally give its okay for a launch:

The FWS has as long as 135 days to complete its review.

Let’s review the situation to understand what this tidbit means. At present it appears the FAA is ready to issue a launch licence, having closed its own investigation into the April Starship/Superheavy test flight on September 8, 2023.

At the time the FAA however was very clear: No launch license until Fish & Wildlife gave its environmental approval as well. Never before had this environmental agency had veto power over launches, but under the Biden administration it now has it.

Though Fish & Wildlife could have begun its own investigation in April, and met the 135-day deadline to give its approval for a launch the same time as the FAA, in September, it now appears that it did not start its clock ticking until after the FAA closed its work. If so, it appears Fish & Wildlife has until early January to complete its investigation.

Since FWS admitted in April, right after the failed test launch of Starship/Superheavy, that it caused no harm to wildlife, there appears no reason for this long delay.

The delay therefore can only be for two reasons, neither good. Either the people at Fish & Wildlife are utterly incompetent, and need eight months to write up the paperwork (even though in April they already knew that there was no reason to delay), or they are vindictive, power-hungry, and wish to exercise an animus against SpaceX in order to hurt the company.

Mostly likely we are seeing a combination of both: The bureaucrats at Fish & Wildlife are incompetent and hate SpaceX, and are using their newly gained power over issuing launch licenses to hurt it.

Either way, if Fish & Wildlife uses its entire 135-day window to issue its launch approval to SpaceX, no launch can occur this year. SpaceX will be stymied, and the development of this new heavy-lift reuseable rocket, possibly the most important new technology in rocketry ever, will be badly crushed. Not only will NASA’s Artemis program be damaged (it wants Starship as its manned lunar lander), SpaceX might face huge financial loses, as it needs Starship to launch and maintain its Starlink communications constellation.

ULA sets Christmas Eve as launch date for first Vulcan rocket launch

8:35 am

In an interview for CNBC, ULA’s CEO revealed that the company has now scheduled the first orbital launch of its new Vulcan rocket for December 24, 2023, Christmas Eve, with a backup launch window in January.

The rocket will carry Astrobotic’s Peregrine lunar lander, targeting the western edge of the lunar mare dubbed Mare Imbrium. It will also carry human ashes to be buried in space, from the private company Celestis.

Vulcan was also originally supposed to carry Amazon’s first two test Kuiper satellites, but the delays in developing Vulcan forced ULA to use an Atlas-5 rocket instead, that launched on October 6th.

If the launch is successful, the company will try to quickly ramp up its launch pace to 24 times per year, in order to meet the contract for 47 launches it has with Amazon to launch Kuiper satellites, as well as its contract obligations to the Pentagon to launch military satellites.

Since Juno completed its 55th close swing past Jupiter on October 15, 2023, including the closest fly by of its volcano-covered moon Io since the 1990s, citizen scientists have been grabbing the spacecraft’s raw images of the moon and enhancing them to bring out the details.

Immediately after the fly-by I posted on October 17, 2023 the top image to the right, processed by Ted Stryk. This version attempted to capture the view of Juno is natural color. As I noted then, “The dark patches are lava flows, with the dimensions of mountains along the terminator line between night and day clearly distinguishable.”

The bottom picture to the right was first processed by citizen scientist Gerald Eichstädt, who like Stryk attempted to capture Io’s natural colors. Thomas Thomopoulos then took Eichstädt’s image and enhanced the colors as well as reduced the brightness, in order to bring out the details as much as possible.

I have rotated, cropped, and reduced this bottom image further to post it here.

In comparing this image with earlier pictures of Io, taken by both Juno and Galileo in the 1990s, there is evidence that some of the lava flows visible now have changed significantly in the intevening time. This is not a surprise, as volcanic eruptions take place on Io so frequently that it has not unusual to capture one in the rare times close up images are possible, going back to the discovery of volcanic activity by Voyager-1 in 1979.

It will take a bit of time for scientists, both professional and amateur, to pick out the specific changes. That work will be further aided by Juno’s next fly-by on December 30, 2023, where it will dip to less than 1,000 miles of the surface.

At the moment our modern Nazi movement appears to be winning

12:25 pm

Chamberlain in 1938
In 1938 Chamberlain thought he could negotiate
with Hitler. Today American politicians think
they can negotiate with Hamas.

Now that we have clear evidence that the left is nothing more than a revised but reborn Nazi movement — allied with murderous Islamic groups like Hamas, it is imperative we track whether the good people in the world are willing to fight it, or appease it as was done so stupidly in the 1930s when Hitler first began his march for world domination and the extermination of the Jews.

In the past week, it seems more and more that appeasement is the watchword of the day.

First, Israel has repeatedly delayed its invasion into Gaza, mostly because of demands from western leaders, led by Democrat Joe Biden, to hold off so that negotiations can continue to get the hostages released. A news report today further reiterated that Israel has agreed to hold off, pending these negotiations.

The reasoning from Israel is the hope that Hamas will release a “big number” of hostages quickly, such as all women and children. Getting one or two hostages released on a weekly basis — which is what Hamas is presently doing — is not considered acceptable to Israel. At that pace it will take more than two years to get all released, and based on how the news cycle goes, after a few more months Israel will have lost its military initiative and Hamas will likely stop releasing any hostages.

Scientists: The solar cycle was only 8 years long during the Maunder Minimum in the 1600s

9:58 am

Using archival records gathered in Korea during the 1600s when the Sun was undergoing a long period of almost no sunspots — called the Maunder Minimum — scientists have discovered evidence that the solar cycle during that time was only 8 years long.

You can read their paper here. Since almost no sunspots were visible at that time, the scientists used reports of aurora in Korea to determine periods when the Sun was more active. From their abstract:

By analyzing the variations in solar activity-related equatorial auroras recorded in Korean historical books in the vicinity of a low-intensity paleo-West Pacific geomagnetic anomaly, we find clear evidence of an 8-year solar cycle rather than the normal 11-year cycle during the Maunder Minimum.

This 8-year cycle is shorter than the 9-year cycle that other researchers had estimated based on the few sunspots that did appear during this grand minimum. Both conclusions however challenge what is known of the Sun. Since the 11-year cycle resumed in the 1700s, short cycles have generally been associated with very active periods, the opposite of what has been found during Maunder.

In other words, we know better what happened, but have no understanding of why. Since the Maunder Minimum appears associated with the Little Ice Age of the 1600s, and fits other data that says the climate cools when the Sun produces few sunspots, gaining some understanding of this process is important for understanding past and future changes to the global climate.

India releases on-board camera views during its Gaganyaan launch abort test

9:46 am

India’s space agency ISRO today released the on-board camera views taken during its Gaganyaan launch abort test on October 21, 2023.

The test was a complete success, and the footage shows each step clearly, from launch to stage separation to deployment of parachutes.

ISRO is still targeting 2024 for the first manned Gaganyaan mission, which will carry two to three astronauts into orbit for three to seven days. To meet that target however will require a lot of fast work, as the agency intends to fly three separate unmanned orbital missions of the Gaganyaan capsule prior to putting humans in it. More likely the manned mission will happen in 2025.
