SpaceX successfully completes static fire tests of both Superheavy and Starship

12:37 pm

SpaceX today successfully completed static fire tests on both Superheavy and Starship prototypes intended to fly on its next orbital test flight.

The video at the link is four hours long. The Starship engine burn occurs at 1 hour 15 minutes and lasts about five seconds. The Superheavy burn takes place at 2 hours 42 minutes, and lasts about ten seconds. Both burns appeared to operate exactly as planned, though obviously an inspection of the launchpad under Superheavy will have to take place to see if its deluge system operated as intended.

Once again, SpaceX is demonstrating that it will be ready to go for the third orbital test launch of this rocket in mere weeks. Based on these tests today as well as past operations, it seems that all the company needs to do now is stack Starship on top of Superheavy, do another dress rehearsal countdown, and then go.

It won’t however. There is no word from the FAA on when it will issue a launch permit. Based on the previous launch, it will likely not issue the permit when SpaceX says it has completed its investigation of the last launch and is ready to fly again. Instead it will take another month or two writing up its own report (which will essentially reword what SpaceX has told it). Then, once the FAA is finished only then will the Fish and Wildlife Service begin to write up its report (as happened in the fall), causing further delays.

I repeat my prediction from November: No launch until March, at the earliest. The federal government continues to stand in the way of progress, and freedom.

Republicans propose another deep state bureaucracy to enforce civil rights laws

12:10 pm

Failure Theater!

Failure theater: In their typically impotent attempt to fight the leftist movement that is imposing a new racial bigotry across America, several Republicans in Congress have proposed a new special government office in Washington that will be specifically assigned the job of preventing racial discrimination at universities.

The College Admissions Accountability Act, introduced by Sen. J.D. Vance (R., Ohio) and Rep. Jim Banks (R., Ind.), would establish a special inspector general within the Education Department—separate from the Office of Civil Rights—to probe potential violations of the colorblind standard set forth in Students for Fair Admissions v. Harvard, which ruled that race-conscious admissions programs violate the 14th Amendment. The bill would also bar schools that flout the decision from receiving any form of federal aid.

…The bill, which appropriates $25 million for the new role and is cosponsored by Sens. Ted Budd (R., N.C.), Mike Braun (R, Ind.), Josh Hawley (R., Mo.), Eric Schmitt (R., Mo.), and Marco Rubio (R., Fla.), does include a sunset clause that would terminate the office after 12 years. Republicans seem to be betting that recalcitrant universities will, after a decade of robust enforcement, throw in the towel and evolve colorblind norms.

These senators and congressmen, along with several conservative think tanks, think naively that this office will the place for anyone of any race to go to get justice should a university receiving federal funds create a program that specifically excludes them solely because of their race. The aim will supposedly be to target specifically the new Diversity-Inclusion-Equity programs at universities and in governments that are imposing this new discrimination against whites, Asians, and Jews.

The foolishness of this plan is hard to measure. » Read more

The ancientness of rocks on Mars

10:31 am

Ancient rocks on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on December 27, 2023 by the high resolution camera on the Mars rover Curiosity. It shows what is a somewhat typical rock found on the ground as Curiosity climbs Mount Sharp in Gale Crater.

Two features stand out. First, the many layers illustrate again the cyclical nature of Martian geology. Many sedimentary events occurred over a long time to create this rock, each cycle putting down a new layer, with some intervening time periods possibly removing layers as well. Such layering has now become evident in both ground photos taken by rovers as well as orbital images.

Second, the delicate nature of some layers indicates the incredibly slow erosion process on Mars, enhanced by the red planet’s one-third gravity. The atmosphere is incredibly thin, less than 0.1% of Earth’s. Yet given time the wind had been able to wear away the edges of this rock. The thin atmosphere and light gravity has also allowed some material to remain in a delicate manner that would be impossible on Earth.

Thus, for these thin flakes to have formed has required a great deal of time. The very nature of this rock speaks of an ancient terrain, shaped slowly by inanimate processes with no active life around to disturb things.

Curiosity science team releases movies of Mars from dawn to dusk

9:32 am

Using its front and rear hazard avoidence cameras, the Curiosity science team had the rover take two full sets of images looking in one direction for twelve hours straight in order to create two movies of Mars that show an entire day, from dawn to dusk.

I have embedded both movies below. From the press release:

When NASA’s Curiosity Mars rover isn’t on the move, it works pretty well as a sundial, as seen in two black-and-white videos recorded on Nov. 8, the 4,002nd Martian day, or sol, of the mission. The rover captured its own shadow shifting across the surface of Mars using its black-and-white Hazard-Avoidance Cameras, or Hazcams.

Instructions to record the videos were part of the last set of commands beamed up to Curiosity just before the start of Mars solar conjunction, a period when the Sun is between Earth and Mars. Because plasma from the Sun can interfere with radio communications, missions hold off on sending commands to Mars spacecraft for several weeks during this time.

The first looks forward, into Gediz Vallis, where Curiosity will eventually travel. The second looks back down Mt Sharp and out across the rim of Gale Crater.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Kazakhstan approves Russia use of Baikonur through 2024

9:22 am

Though Russia supposedly has a long term lease for launching rockets from its Baikonur spaceport in Kazakhstan, Kazakhstan this week revealed that it has just now approved the Russian plan of launches there for 2024.

The Government of Kazakhstan approves the plan of spacecraft launches for 2024 presented by the Russian side within the framework of the state program of the Russian Federation “Space Activities of Russia”, programs of international cooperation and commercial projects from Baikonur Cosmodrome.

Kazakhstan has increasingly become a bit hard-nosed about Russia’s long term lease. For example, in March seized control of the launchpad Russia hoped to use on its new Soyuz-5 rocket, leaving that rocket with no place to launch. And for the last decade there have been hints from both countries that the deal is souring, with Russia suggesting it will shift launch operations entirely to its new spaceport in Vostochny and Kazakhstan politicians eager to see Russia go.

China completes work on first dedicated “commercial” launchpad

9:08 am

China announced today that it has completed work on first launchpad at its Wenchang spaceport on the island of Hainan off the southern coast of China that it intends to dedicate to launches by its many pseudo-private companies.

Construction of the No. 1 launch pad started in July 2022, and the equipment-installation phase is almost complete. The No. 2 launch pad is still at the construction phase, with the capping of the diversion trough’s main body now finished. On-site equipment installation is due to be completed by the end of May 2024.

The article also notes that this pad is a dedicated site for launching China’s new Long March 8 rocket, which means it isn’t really dedicated to commercial launches at all. These pseudo-companies might use it, but they will do so under orders from the communist Chinese government, which supervises everything they do.

Russia and NASA agree to extend ISS astronaut exchanges on each other’s spacecraft through 2025

9:01 am

Russia and NASA have agreed to extend their barter deal through 2025, whereby each nation sends astronauts to ISS periodically on the other nation’s rockets and capsules.

This is a barter deal, with no exchange of money. The fundamental idea is to make sure astronauts on board ISS understand how the capsules from each nation operate in case of emergency. Russia had initially resisted signing such a deal after SpaceX began providing NASA its Dragon capsules and Falcon 9 rocket to get astronauts to ISS. It said this was because it did not trust SpaceX’s technology, but I suspect Roscosmos was also hoping to squeeze some cash from NASA as it was no longer being paid to fly U.S. astronauts on its Soyuz rocket and capsule. That attempt was futile. For numerous political reasons there was no way NASA was going to pay Russia anything in this barter deal.

Russia then signed on, and will keep extending this agreement until the day ISS is retired, or it finally launches its own station (something that is becoming increasingly unlikely).

Navaho Indians attempt to claim ownership of the Moon, delay Vulcan launch

8:47 am

The president of the Navaho Nation has asked NASA to delay the first launch of ULA’s Vulcan rocket because it carries ashes from a number of people (none who were members of its tribe) that Astrobotic’s Peregrine lander will place on the Moon.

The remains are a payload purchased by the company Celestis, which offers this burial option to anyone who wishes it. On this flight that payload includes a wide range of ashes, including many actors and creators from the original Star Trek series.

Navaho President Buu Nygren claims that the “Moon is sacred to numerous Indigenous cultures and that depositing human remains on it is ‘tantamount to desecration.'”

Nygren highlighted this commitment in his letter, as well as a 2021 memo signed by the Biden administration that pledged to consult the tribe on matters that impact them. “This memorandum reinforced the commitment to Executive Order 13175 of November 6, 2000,” President Nygren wrote. “Additionally, the Memorandum of Understanding Regarding Interagency Coordination and Collaboration for the Protection of Indigenous Sacred Sites, which you and several other members of the Administration signed in November 2021, further underscores the requirement for such consultation.”

In other words, though the Navaho have no plans to ever go there, have done nothing to try to explore it, and have no remains of any tribal members on the flight, he wants to claim the Moon as controlled entirely and forever by the Indian tribes of North America because of a law designed solely to protect specific archeological sites on Earth, where Indian remains are discovered.

SpaceX’s Falcon Heavy rocket launches the Space Force’s X-37B

6:15 pm

SpaceX’s Falcon Heavy rocket tonight successfully launched one of the two X-37B reuseable mini-shuttles in the Space Force’s fleet, lifting off from Cape Canaveral.

This was the seventh X-37B flight. It is not clear which of the two vehicles was flying, and how many flights it has completed previously. The previous X-37B flight stayed in orbit for a record 908 days, landing safely in November 2022.

The two side boosters completed their fifth flight, landing safely back at Cape Canaveral. The center core was treated as expendable, and was not recovered.

The leaders in the 2023 launch race:

95 SpaceX (with another launch scheduled later tonight)
65 China
19 Russia
8 Rocket Lab
7 India

American private enterprise now leads China in successful launches 109 to 65, and the entire world combined 109 to 102. SpaceX in turn trails the rest of the world (excluding other American companies) 95 to 102.

Today’s blacklisted American wins $185K settlement from college that fired him

1:45 pm

St. Philip's College, home to blacklisting and censorship
St. Philip’s College, the poster child of academic
blacklisting and censorship

They’re coming for you next: Today’s blacklist story is a follow-up on a July 2023 essay about the oppressive atmosphere at St. Philip’s College in Texas, where two different professors were fired in 2023 for political reasons.

First, Dr. Johnson Varkey, was fired because in teaching human anatomy he had the audacity to mention that sex is determined by the X and Y chromosomes, a very basic fact of biology that any medical student has to know to become a competent doctor. Four students walked out on him for saying so, and when they complained to the administration it fired him without due process. He is presently suing the college.

Then, college officials fired professor Will Moravits because he insisted on allowing free and open debate in his classroom and one anonymous student complained, and while doing so made false accusations against Moravits. The school felt so threatened by the idea of freedom of speech that it had Moravits escorted off campus by police, never to return.

Moravits has now won a $185K settlement with St. Philip’s College.

Mapping the major lava flood events in Mars’ volcano country

12:10 pm

The volcanic events in Mars' volcano country
Click for original map.

In a paper just released, scientists have used the orbital data from Mars Reconnaissance Orbiter (MRO) to map on Mars forty different past volcanic eruptions of extensive flood lava covering large regions, all within the region I dub “volcano country” because its entire surface seems mostly shaped by flows of lava.

The map above, figure 1 from the paper, shows the study area (within the white rectangle), with its global context and additional information added by me on the right. Most of the largest earthquakes detected by InSight ran from north-to-south down the center of the white box. The named features are all large flood lava events, with the youngest being Athabasca. Within the Cerburus Plains feature the researchers mapped many smaller events which brought the total up to forty. From the abstract:

An area almost as large as Europe was investigated. The study revealed the products of more than 40 volcanic events, with one of the largest flows infilling Athabasca Valles with a volume of 4,000 km3. The surface appearance and material properties suggest that Elysium Planitia is composed of basalt, the most common type of lava on Earth. The area also experienced several large floods of water, and there is evidence that lava and water interacted in the past. However, while there could be ice in the ground today, it likely occurs in small patches.

None of these flood lava events involved the gigantic volcanoes that surround this region. Instead, the lava erupted from vents within this region, and then flowed downgrade to flood large areas, sometimes covering over parts of earlier lava floods. All also flowed much faster than lava on Earth, flooding vast regions — comparable to entire countries — often in mere weeks.

Juno’s closest image of Europa suggests recent surface activity

11:18 am

Juno's best image of Europa
Click for original image.

Analysis by scientists of the closest image of Europa taken during Juno’s close-fly on September 29, 2022 suggests that a particular strange feature, dubbed the “platypus” due to its shape, might be very young and indicate recent surface activity that could be related to underground liquid water.

That picture, reduced and sharpened to post here, is to the right. It is figure 2 of the paper. The description of this photo from the abstract:

Intricate networks of cross-cutting ridges and lineated bands surround an intriguing 37 km (east-west) by 67 km (north-south) chaos feature with a concentric fracture system, depressed matrix margins, and low-albedo materials potentially associated with brine infiltration. The morphology and local relief of the chaos feature are consistent with formation in the collapse of ice overlying a salt-rich lens of subsurface water. Low-albedo deposits, similar to features previously associated with hypothesized cryovolcanic plume activity, flank nearby ridges. The SRU’s high-resolution view of many types of features in a single image allows us to explore their regional context and greatly improve the geologic mapping of this part of Europa’s surface. The image reveals several relatively youthful features in a potentially dynamic region, providing baselines for candidate locations that future missions can investigate for present day surface activity.

SRU is Juno’s Stellar Reference Unit camera, designed to take pictures using only the low light of Jupiter reflected onto nighttime surfaces of Jupiter’s moons. It took this photo when Juno was only 256 miles above the surface.

This feature will obviously become a prime target for Europa Clipper when it arrives into orbit around Jupiter in April 2030. From this vantage point — safer than continuous exposure to Jupiter’s magnetosphere while in orbit around Europa — the spacecraft will do 44 close-flys of the moon.

Japan’s SLIM lunar lander releases its first pictures of Moon

Oblique view of Moon by SLIM

Japan’s space agency JAXA today released the first pictures taken of the Moon by its SLIM lunar lander after entering lunar orbit on December 25, 2023.

Three images were included in the tweet. The one to the right, reduced to post here, gives an oblique view of the Moon, including its horizon. None of the images are of great scientific value, but all are very significant in terms of SLIM’s engineering. They prove the spacecraft is operating as designed, able to orient itself precisely as well as point its camera correctly. These facts bode well for the precision landing attempt, which is SLIM’s main purpose, now targeting January 24, 2024. The primary goal is to demonstrate the ability for an unmanned spacecraft to land autonomously within a tiny landing zone only 300 feet across.

If SLIM succeeds, it will then hopefully operate for one lunar day, about two weeks. It is not expected to survive the lunar night that follows.

The uncertainty of science as proven by the Webb Space Telescope

9:38 am

A long detailed article was released today at Space.com, describing the many contradictions in the data coming back from the Webb Space Telescope that seriously challenge all the theories of cosmologists about the nature of the universe as well as its beginning in a single Big Bang.

The article is definitely worth reading, but be warned that it treats science as a certainty that should never have such contradictions, as illustrated first by its very headline: “After 2 years in space, the James Webb Space Telescope has broken cosmology. Can it be fixed?”

“Science” isn’t broken in the slightest. All Webb has done is provide new data that does not fit the theories. As physicist Richard Feynman once stated bluntly in teaching students the scientific method,

“It doesn’t make a difference how beautiful your guess is, it doesn’t make a difference how smart you are, who made the guess, or what his name is. If it disagrees with experiment, it’s wrong.”

Cosmologists for decades have been guessing in proposing their theories about the Big Bang, the expansion of the universe, and dark matter, based on only a tiny amount of data that had been obtained with enormous assumptions and uncertainties. It is therefore not surprising (nor was it ever surprising) that Webb has blown holes in their theories.

For example, the article spends a lot of time discussing the Hubble constant, describing how observations using different instruments (including Webb) have come up with two conflicting numbers for it — either 67 or 74 kilometers per second per megaparsec. No one can resolve this contradiction. No theory explains it.

To me the irony is that back in the 1990s, when Hubble made its first good measurements of the Hubble constant, these same scientists were certain then that the number Hubble came up with, around 90 kilometers per second per megaparsec, was now correct.

They didn’t really understand reality then, and they don’t yet understand it now.

What cosmologists must do is back away from their theories and recognize the vast areas of ignorance that exist. Once that is done, they might have a chance to resolve the conflict between the data obtained and the theories proposed, and come up with new theories that might work (with great emphasis on the word “might”). Complaining about the paradoxes will accomplish nothing.

Japan’s space agency JAXA schedules next H3 rocket launch

9:11 am

JAXA, Japan’s space agency, announced today that it has now scheduled the next test launch of its new H3 rocket for February 15, 2024.

This rocket, built by Mitsubishi for JAXA, is supposed to replace the H2A rocket, which completed its last launch in September 2023. The H3 was supposed to be flying years ago, but has experienced numerous engineering problems throughout its development. It was initially supposed to launch in 2020, but was first delayed to 2021 because of “engine issues,” which were later described as cracks and holes in the engine’s combustion chamber.

That launch date was never met. When JAXA was gearing up to launch in 2022 news sources revealed another yearlong delay until 2023 because of new engine problems, which appeared to require a complete engine redesign.

Then in February 2023 the rocket’s first launch attempt was aborted at T-0 when the two strap-on solid rocket boosters failed to ignite. A second launch attempt a month later failed when the second stage failed during launch.

Even if the rocket successfully launches in February, it still leaves Japan far behind the rest of the space-faring industry. The H3 is entirely expendable, and is far more expensive to launch than the new reuseable rockets in use or being developed by numerous private American companies or other nations. JAXA says it hopes to launch it six times a year, but I can’t imagine it getting even a third that number of customers.

What Japan’s government really needs to do is to get the launch business away from JAXA completely. Let other companies besides Mitsubishi build their own rockets and have JAXA buy their services, rather than try to design its own rockets. This system is working marvelously in the U.S., so much so that India is now aggressively trying to copy it, while communist China has made its own pseudo attempt, somewhat successfully, to do the same for the past five years.

All I feel is fury at the bankruptcy of academia decades ago

1:55 pm


A modern Ivy League education: “But Brawndo’s got what plants crave.
It’s got electrolytes!”

Recently Bari Weiss, former New York Times journalist who it blacklisted because she refused to follow the leftist narrative when the facts said otherwise, wrote a heart-wrenching column about the fall of American academia. She began as follows:

Twenty years ago, when I was a college student, I started writing about a then-nameless, niche ideology that seemed to contradict everything I had been taught since I was a child.

…What I saw was a worldview that replaced basic ideas of good and evil with a new rubric: the powerless (good) and the powerful (bad). It replaced lots of things. Color blindness with race obsession. Ideas with identity. Debate with denunciation. Persuasion with public shaming. The rule of law with the fury of the mob.

People were to be given authority in this new order not in recognition of their gifts, hard work, accomplishments, or contributions to society, but in inverse proportion to the disadvantages their group had suffered, as defined by radical ideologues. According to them, as James Kirchick concisely put it: “Muslim > gay, black > female, and everybody > the Jews.”

I was an undergraduate back then, but you didn’t need a PhD to see where this could go. And so I watched, in horror, sounding alarms as loudly as I could.

I was told by most Jewish leaders that, yes, it wasn’t great, but not to be so hysterical. Campuses were always hotbeds of radicalism, they said. This ideology, they promised, would surely dissipate as young people made their way in the world.

It is essential to repeat her second paragraph again to understand the utter bankruptcy of this new “philosophy.” It was…

… a worldview that replaced basic ideas of good and evil with a new rubric: the powerless (good) and the powerful (bad). It replaced lots of things. Color blindness with race obsession. Ideas with identity. Debate with denunciation. Persuasion with public shaming. The rule of law with the fury of the mob.

China launches four more weather satellites

11:43 am

Continuing its annual rush of launches at year’s end, China today used its solid-fueled Kuaizhou-1A rocket to place four weather satellites into orbit, lifting off from its Jiuquan spaceport in the northwest of China. This was the second launch of this rocket with four weather satellites in less than three days.

No word on where the rocket’s lower stages crashed in China, or whether they landed on anyone’s home, as did the core stage of yesterday’s Long March 3B rocket.

The leaders in the 2023 launch race:

94 SpaceX
65 China
19 Russia
8 Rocket Lab
7 India

American private enterprise still leads China in successful launches 108 to 65, and the entire world combined 108 to 102. SpaceX in turn trails the rest of the world (excluding other American companies) 94 to 102.

Hat tip to Jay, as I had missed this because I had mistakenly first thought it was the Kuaizhou-1A launch from two days ago, not a second launch.

Isolated mesa on Mars

11:33 am

An Isolated mesa on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 13, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The central butte is about 100 feet high. Not only are its flanks terraced, suggesting sedimentary layers, note the many black dots on its northern slopes. Those dots appear to be many boulders that appear to have rolled down the slopes to settle mostly near the mesa’s base.

The boxwork ridges to the west and south suggest the ground was fractured in some event to produce cracks, which were later filled with material that was erosion resistent. As the terrain was worn away by wind it left these ridges behind.

The prevailing winds in this region are believed to blow mostly to the south, which might explain the parallel ridges south of the mesa. Or not. On this I am guessing entirely.

Update on Ingenuity

9:56 am

Overview mapClick for interactive map.

The overview map above shows the travels of both the rover Perseverance and the helicopter Ingenuity on Mars through today, with the blue dot marking Perseverance’s present location and the green dot Ingenuity’s. Because of image downloads today from Perseverance — including a few more pictures taken by the helicopter during several of its recent flights — the helicopter’s engineering team has finally been able to add the flight paths for flights #68, #69, and #70 to this map, as well as provide more accurate information about what each accomplished..

Flight #68, which took place on December 15, 2023, a few days later than originally planned, as I reported on December 20, 2023 when the first preliminary data arrived. At the time it appeared the flight had ended prematurely by almost 1,500 feet. We now know the flight did end early, but by not that much. Instead of flying, as per its flightplan, to the northeast 2,716 feet for 147 seconds and then returning to its take-off point, it flew out and back 2,304 feet for 131 seconds. The engineering team has not explained why it turned around prematurely by about 200 feet.

Flight #69 on December 20, 2023 was supposed fly 2,304 feet total over 131 seconds, also going out and back, traveling to the east-northeast. It ended up flying 2,315 feet over 135 seconds on a flight path that was almost identical to flight #68. Like most previous flights, it appears it hovered over its landing spot for a few extra seconds before descending in order to make sure it would land safely.

The final numbers for flight #70 have not yet been added to the flight log, but the engineering team has apparently been able to figure out the path the helicopter took and where it landed from the images that have been downloaded in the past few days. The flight plan had called for a relatively short flight, 849 feet long, but taking almost as long as the previous two, 129 seconds, thus allowing Ingenuity to get better and more detailed scouting pictures of the terrain below it for scientists to review.

One more detail: It appears that the Perseverance science team has decided to use Ingenuity data to guide its route. Rather than follow the planned course, as indicated by the red dotted line, the rover has been following the ground scouted by Ingenuity on its 63rd flight on October 19, 2023. This has taken Perseverance deeper into the rough fractured terrain to the south, where it likely can obtain better geological data.

It also suggests that Ingenuity’s more recent flight paths are giving us a hint as to Perseverance’s future travels.

Russia launches military satellite

8:49 am

Russia today successfully placed a classified military satellite into orbit, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in the north of Russia.

No other information was released, including where the rocket’s strap-on boosters and core stage crashed inside Russia.

The leaders in the 2023 launch race:

94 SpaceX
64 China
19 Russia
8 Rocket Lab
7 India

American private enterprise still leads China in successful launches 108 to 64, and the entire world combined 108 to 101. SpaceX in turn trails the rest of the world (excluding other American companies) 94 to 101.

Record-setting Falcon 9 1st stage booster lost after landing

3:27 pm

The SpaceX Falcon 9 first stage booster that launched on December 23, 2023 for a record-setting nineteenth time was damaged beyond repair when, after landing on its drone ship successfully, experienced rough seas that caused it to fall over.

The picture at the link shows the crushed booster on its side on the drone ship. SpaceX noted the spectacular history of this booster in a separate tweet:

This one reusable rocket booster alone launched to orbit 2 astronauts and more than 860 satellites — totaling 260+ metric tons — in ~3.5 years.

In a sense, it actually put more mass into orbit that a Saturn 5 rocket, for significant less money though over a much longer period of time.

For SpaceX the loss of this booster is hardly a set back, because it has several other boosters with only a few less total launches in its fleet. Expect one to exceed twenty launches in the near future.

Hat tip to out stringer Jay as well as several readers.

The violent animals on the left who support Hamas

Hamas protesters threaten blind children
Hamas protesters threaten blind children

I am in no mood this day to be polite or diplomatic. The ugliness exhibited in the past week by pro-Hamas demonstrators — using the violent techniques of Antifa and BLM and copying Nazi storm-trooper tactics — deserve no politeness. They are no longer acting like civilized rational human beings, but mere animals eager to kill and only held back from that goal by the last few shreds remaining of civilization’s rule of law.

Thus, at this moment they only attack innocent people in ugly ways, not intending to kill but clearly hoping to intimidate and strike fear into the hearts of everyone else. Some examples from the past three days:

The last story in this list is especially egregious. The screen capture above shows two demonstrators on stage. In the video at the link they are screaming and yelling, with the one on the right charging at the children in a threatening manner. Remember, this is a fund-raiser for blind children. Those kids cannot see, so all they know is that someone unexpected has appeared on the stage and is screaming at them, and their helpers are desperately trying to get them to safety.

This behavior illustrates perfectly the hatred and viciousness of all these pro-Hamas demonstrators. » Read more

Galaxies galore, near and far

Galaxies galore, and near and far

Cool image for the day after Christmas! The picture to the right, reduced and sharpened to post here, was taken by the Hubble Space Telescope, and shows a cluster of galaxies that all seem near each other. However, as the caption notes,

[W]hilst NGC 1356 [the largest spiral] and LEDA 95415 [close by its left] appear to be so close that they must surely be interacting, the former is about 550 million light-years from Earth and the latter is roughly 840 million light-years away, so there is nearly a whopping 300 million light-year separation between them. That also means that LEDA 95415 is likely nowhere near as [small] as it appears to be.

On the other hand, whilst NGC 1356 and IC 1947 [farthest to the left] seem to be separated by a relative gulf in this image, IC 1947 is only about 500 million light-years from Earth. The angular distance apparent between them in this image only works out to less than four hundred thousand light-years, so they are actually much much closer neighbours in three-dimensional space than NGC 1356 and LEDA 95415!

The two galaxies farthest apart in this image are actually close enough together to interact significantly. Though this picture doesn’t have the resolution to see it, there is likely a stream of stars between the two.

Note also the numerous tiny other galaxies scatterered throughout the picture. In fact, except for three stars (the objects with the north-south-east-west spikes), every object is a galaxy holding stars too numerous to count.
