    This appears to be the first time Cobalt-60 has ever been used. From Jay: “It is easy to make Co-60, just bombard iron with neutrons. It happens all the time at nuclear reactors when stray neutrons hit steel, but it has a short half life of five years. It puts outs beta decay, that is what they are using for heat, but the gamma rays it puts out worries me with the electronics. They probably licked that problem or else they would not do it.”

Have Americans finally awakened? Early voting suggests yes

2:02 pm

Rick, stating the truth in Casablanca
Have ordinary Americans finally awakened to the
anti-American plans of the Democratic Party?

For the past few weeks early voting data from a variety of states has begun to suggest a major shift in what have been the traditional voting patterns for decades. In the past, Democrats routinely dominating early mail-in voting, while Republicans instead went to the polls on election day.

This election season is seeing an almost Earth-shattering change.

Nor are these three states outliers. A look at a nationwide map of early voting shows that Republicans also lead in Georgia and Arizona. Though the overall numbers nationwide show a Democrat-Republican split of 46% to 36%, the number of early votes from Republicans this election is far higher than in the past.

Though caution must be exercised, and we must recognize that these numbers do not guarantee a win for Donald Trump, what the data suggests however is an amazing newfound voting enthusiasm among Republicans. » Read more

The obvious visual evidence for assuming Mars once had catastrophic floods

12:03 pm

The obvious visual evidence of past catastropic floods on Mars
Click for original image.

Since the first comprehensive orbital data of Mars was sent back in the early 1970s by Mariner 9, scientists have generally concluded that many of the features seen at the eastern end of the giant Valles Marineris canyon were caused by one or several catastrophic floods.

The picture to the right, rotated, cropped, and reduced to post here and taken on July 26, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), provides a good example of why the scientists have come to that conclusion. It shows what the camera team labels a “streamline feature surrounding crater.” I have added the arrows to indicate the presumed direction of flow. The flow went around this 2.5-mile-wide unnamed crater because the impact had compacted it, making it resistent to erosion. The flow however was strong and large enough to wash away the plateau on which the crater sits, as well as cutting into the crater’s southwest rim. In addition, the rim on the southeast was also cut through at some point, this time from what might have been flow eddies as the flood pushed past.

Hence, the theory of catastrophic floods.

SpaceX asks FCC for license revision for launching nearly 30,000 Starlink satellites

8:51 am

SpaceX on October 11, 2024 submitted a request to the FCC to revise its Starlink satellite license to cover a revised plan for its second generation satellites that includes a request to place 29,988 Starlink satellites in orbit.

SpaceX first requests several amendments to the orbital parameters of its Gen2 system between 340 km and 365km altitude to keep pace with rapidly evolving global demand for high-quality broadband. First,SpaceX amends the inclination of its orbital shell at a nominal altitude of 345 km from 46 degrees to 48 degrees. SpaceX also amends its pending Gen2 application to seek authority to operate satellites in its Gen2 system in two additional orbital shells — at 355 km altitude in a 43-degree inclination and at 365 km altitude in a 28- or 32-degree inclination. The total number of operational satellites will remain 29,988 satellites across the amended Gen2 system.

With the exception of its polar shell at 360 km, which will remain unchanged, SpaceX also amends its application to more flexibly distribute satellites in its shells between 340 km and 365 km than requested in its pending application, specifically, in up to 72 planes per shell and up to 144 satellites per plane. While this reconfiguration will result in two additional shells and a higher maximum number of orbital planes and satellites per plane for all but one shell between 340 km and 365 km, the total number of operational satellites in the Gen2 system will remain 29,988 satellites.

In the company’s previous request for this number of satellites, the FCC had approved only 7,500, the full request still pending. We can expect objections from the other big satellite constellations to this request. The FCC’s response remains unclear. There could be legitimate reasons to limit SpaceX request, but it is also possible politics will enter the decision as well, for illegitimate reasons.

Meanwhile, astronomers are already whining about the problems these Starlink satellites will cause to their ground-based telescopes. It seems these so-called brilliant scientists can’t get it through their heads that astronomy from Earth will become increasingly difficult in the coming years — with hundreds of thousands of satellites planned from many satellite constellations, not just SpaceX — while astronomy from space has always been a better choice anyway. Rather than demand regulation or restrictions on these new satellite constellations, they should be pushing hard to developing new orbiting telescopes, now, for launch as quickly as possible.

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 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.

China launches three radar satellites

8:33 am

China today successfully launched three radar satellites, its Long March 6 rocket lifting off from Taiyuan spaceport in northeast China.

The news report from China’s English state-run press made believe this launch was only one satellite, in contrast to its Chinese language press. It also did not provide information on where the rocket’s first stage crashed within China, nor whether any upgrades have been done to the Long March 6’s upper stage to prevent it from breaking apart and scattering low Earth orbit with space junk, as has now happened four times previously.

The leaders in the 2024 launch race:

102 SpaceX
48 China
11 Russia
11 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 119 to 71, while SpaceX by itself now leads the entire world, including American companies, 102 to 88.

Chile to sign Artemis Accords

8:24 am

NASA yesterday invited the media to attend to signing of the Artemis Accords by Chile at the end of this week.

Chile will be the 46th nation to sign. The full list is as follows: Angola, Argentina, Armenia, Australia, Bahrain, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Czech Republic, Dominican Republic, Ecuador, Estonia, France, Germany, Greece, Iceland, India, Israel, Italy, Japan, Lithuania, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Peru, Poland, Romania, Rwanda, Saudi Arabia, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

Though the Biden administration continues to describe the accords as a means for “reinforcing” the Outer Space Treaty — the opposite of its original intent — a new Trump administration will be well positioned with this very large alliance to force changes in the treaty’s limits to private property and capitalism. All that has to happen is a will to demand it. Some of these nations might balk, but I think most will go along, some quite enthusiastically.

Donations and applications to Harvard drop significantly

4:44 pm

Harvard: where you get can get a shoddy education centered on hate and bigotry
Harvard: where you can spend a lot of money
and still get a shoddy education

According to Harvard, donations to the university in 2024 dropped more than $151 million from donations the previous year, with other indications that overall donors and students are fleeing the university due to its anti-Semitic, pro-Hamas, racist DEI, pro-plagiarism, and anti-free speech policies.

Total donations were down by $151 million, or 14%, in fiscal 2024 from the prior year. Within that total, donations to Harvard’s endowment fell by nearly $193 million from a year ago, while donations for current use gifts increased by $42 million in that time frame.

The drop in donations won’t leave Harvard bankrupt, as it still has more than $53 billion in its endowment, giving it a strong foundation for survival, in the near term, if donations dry up entirely.

And they might.

Bill Ackman, a billionaire Harvard alum, said in December that Gay’s “failures have led to billions of dollars of canceled, paused and withdrawn donations to the university. … I am personally aware of more than a billion dollars of terminated donations from a small group of Harvard’s most generous Jewish and non-Jewish alumni,” Ackman said.

More significant however was the 17% decline in student applications as of December 2023. Though the numbers still exceeded application numbers from before the COVID epidemic, the drop now suggests students have reviewed the reality of this college versus its fantasy, and are now beginning to reject it.

Eventually Harvard will have to fix its bankrupt DEI policies as well as diversify its faculity so that not every teacher and staff member is a pro-Hamas anti-Semite who considers America the devil incarnate and all western civilization nothing more than an expression of “white supremacy.” (I know I am exaggerating but I also know sadly not by much.) If it doesn’t it will certainly fade from view, as students find more viable colleges, knowing that a degree from this bankrupt university will no longer get them the high level jobs they want.

Intelsat satellite breaks up in geosynchronous orbit

12:09 pm

An Intelsat communications satellite launched in 2016 has broken up in its high geosynchronous orbit, scattering into as many as 57 pieces of debris.

“U.S. Space Forces-Space (S4S) has confirmed the breakup of Intelsat 33E (#41748, 2016-053B) in GEO on October 19, 2024, at approximately 0430 UTC,” states an alert posted on SpaceTrack, the U.S. Department of Defense’s space-tracking platform. “Currently tracking around 20 associated pieces – analysis ongoing. S4S has observed no immediate threats and is continuing to conduct routine conjunction assessments to support the safety and sustainability of the space domain.”

Douglas Hendrix, CEO of ExoAnalytic Solutions, said the U.S.-based space-tracking company identified 57 pieces of debris Oct. 21 associated with the breakup. “We are warning operators of any spacecraft that we think are at risk of collision,” Hendrix said via email.

This satellite, which served Europe, Africa, and parts of Asia, has had thruster issues since launch, suggesting the breakup might have been caused by similar issues.

At the moment is is unclear whether the debris will threaten other satellites in geosynchronous orbit.

The break-up once again highlights the profit potential for companies capable of removing such space junk. Communications companies like Intelsat as well as others in close orbits would certainly be willing to pay someone to clean things up, for many reasons.

Perseverance’s future increasingly rocky road

11:51 am

Perseverance's uphill route
Click for original image.

Though nothing in any image so far from the Mars rover Perseverance matches the rocky terrain that the rover Curiosity has been traversing for the past two years as it climbs Mount Sharp in Gale Crater, as Perseverance has been climbing up the rim of Jezero Crater in the past few weeks it is beginning to get a hint of a future rougher road.

The photo to the right, cropped, reduced, and sharpened to post here and taken on October 20, 2024 by one of the rover’s high resolution cameras, is a good example. It looks uphill in the direction that the rover will travel. Note how as you go higher the ground appears to be more strewn with rocks and boulders. Another image, taken the same day by the rover’s high resolution camera, shows a close-up of an even more boulder-covered landscape.

A galaxy squashed as it plows its way through the intergalactic medium

9:21 am

A galaxy squashed by a vacuum
Click for original image.

Time for another cool image on this relatively slow day in the space news business. The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope and released today by the European Space Agency’s press department. From the caption:

Appearances can be deceiving with objects so far from Earth — IC 3225 itself [the galaxy to the right] is about 100 million light-years away — but the galaxy’s location suggests some causes for this active scene, because IC 3225 is one of over 1300 members of the Virgo galaxy cluster. The density of galaxies in the Virgo cluster creates a rich field of hot gas between them, the so-called ‘intracluster medium’, while the cluster’s extreme mass has its galaxies careening around its centre in some very fast orbits. Ramming through the thick intracluster medium, especially close to the cluster’s centre, places an enormous ‘ram pressure’ on the moving galaxies that strips gas out of them as they go.

IC 3225 is not so close to the cluster core right now, but astronomers have deduced that it has undergone this ram pressure stripping in the past. The galaxy looks as though it’s been impacted by this: it is compressed on one side and there has been noticeably more star formation on this leading edge, while the opposite end is stretched out of shape. Being in such a crowded field, a close call with another galaxy could also have tugged on IC 3225 and created this shape. The sight of this distorted galaxy is a reminder of the incredible forces at work on astronomical scales, which can move and reshape even entire galaxies!

What makes the impact on this galaxy of that intercluster medium so astonishing is that medium is so relatively empty of material. The space between galaxies in the Virgo cluster is in all intents and purposes a vacuum far more empty than any that we can create in a chamber on Earth. And yet it was enough to distort this galaxy and cause star formation on the galaxy’s leading edge.

Young lava on the Moon?

Young lava on the Moon?
Click for original image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on November 27, 2023 by Lunar Reconnaissance Orbiter (LRO) and was today featured by the science team. From their caption:

One of the early findings from the LRO mission was the discovery of volcanic features known as Irregular Mare Patches (IMPs) scattered across the nearside. These landforms are generally considered volcanic. However, their ages are hotly debated. They may be as young as 50 million years or as old as 3.5 billion years. The Aristarchus IMP (25.045°N, 313.233°E) is one of the smallest and most enigmatic IMP. The fact that this IMP is found within the Aristarchus crater ejecta suggests it formed after the crater, which is dated at 200 million years.

Alternatively, this IMP may have formed as part of ejecta emplacement from the Aristarchus crater forming impact. However, no other crater ejecta on the Moon exhibits a similar landform.

Astronomers for decades before and since Sputnick have reported what appears to be some activity in the Aristachus region, though none of those reports have ever been confirmed. In LRO’s long mission orbiting the Moon it has not yet detected any obvious changes there, suggesting that there is little or no present activity. These patches however appear to indicate activity in the relatively recent past.

The patches however also indicate activity that seems alien. Why would the lava form in this manner, as rough patch of knobs, sometimes aligned, sometimes not?

Oman: 1st launch from Duqm spaceport by the end of the year

2:31 pm

Middle East, showing Oman's proposed spaceport

According to an announcement yesterday Oman plans to complete its first launch before the end of 2024 from its proposed new spaceport near the city of Duqm on the Indian coast.

The map to the right indicates its location. Oman has dubbed the spaceport Etlaq, and it is being run by what Oman claims is a private company, the National Aerospace Services Company (NASCOM), but based on what little I can find out, it appears either to be Oman’s space agency, or a variation of the pseudo-companies in China, privately run but very tightly controlled and owned by government officials.

The announcement provided no information about the rocket or launch, which I suspect will be nothing more than a relatively simple suborbital mission, designed to demonstrate they are serious about this spaceport. The news story at the link shows a picture of a very sophisticated rocket resembling India’s GSLV rocket. I think it is a AI image having nothing to do with reality.

This project was first announced in 2023, with more information released in January 2024. It hopes to attract American rocket companies by claiming it is being built to FAA standards.

SpaceX successfully launches twenty OneWeb satellites

11:33 pm

SpaceX tonight successfully launched twenty OneWeb satellites, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its seventh flight, landing back at Vandenberg. The fairing halves completed their eleventh and thirteenth flights respectively.

SpaceX has done several launches for OneWeb, the chief competitor to its own Starlink constellation. It won the contract when Russian invaded the Ukraine and — in response to new sanctions imposed by Europe — refused to launch a planned OneWeb launch while confiscating the satellites. OneWeb responded by cancelling its last six Soyuz launches, worth as much as a billion dollars, and signed SpaceX and India’s space agency ISRO instead.

Good news: The European Union’s space law is delayed

10:38 am

According to comments by one official of the European Union (EU) at a conference in Italy this week, its proposed space law has been delayed and will not be ready for publication in 2024, as previously promised.

It appears the delay is mostly because of what appear to be complex objections to this law from many of the EU’s many member nations.

Ten of the European Union’s 27 member states “have a full-fledged national space law addressing private-sector operation,” Von der Dunk said. The national laws cover authorization and supervision of commercial activities under Article VI of the 1967 Outer Space Treaty.

The EU’s authority to promote scientific progress and the industrial competitiveness of member states comes from the 2007 Lisbon Treaty. That authority is limited, though. “The commission has to make an argument why [space law] should be treated at the EU level, as opposed to the national level,” Von der Dunk said. [emphasis mine]

As I noted in April 2024 when the release of the EU’s space law was pushed back until the summer of 2024 (which by the way did not happen), those member nations do not wish to give the EU that authority, as the EU’s track record in these kinds of matters is heavy regulation and a lot or red tape, all designed to give it power and squelch private enterprise.

It appears those member nations are acting to block this law, and appear to be succeeding. My guess is that Germany, France, Spain, and Italy are the main opponents, all of which have their own space laws in place and are now developing viable private commercial rocket and spacecraft companies. They don’t want the EU’s busy hands anywhere close to these businesses, because they expect it to squash them if it gets the chance.

Space Force awards SpaceX big launch contract

10:24 am

Space Force yesterday awarded SpaceX a $733 million contract for what appears to be a total of eight future launches of military and national security payloads.

Few details were released about the payloads, including the launch timeline. The deal was issued as part of the military launch contracting system, which in June named SpaceX, ULA, and Blue Origin as its launch providers for the next five years.

However, one official’s comment appeared to suggest this contract award was the military’s expression of disgust at the delays at ULA and Blue Origin in getting their rockets launchworthy.

“In this era of Great Power Competition, it is imperative to not leave capability on the ground,” Brig. Gen. Kristin Panzenhagen, program executive officer for Assured Access to Space, said in an emailed statement on Friday. “The Phase 3 Lane 1 construct allows us to execute launch services more quickly for the more risk-tolerant payloads, putting more capabilities on orbit faster in order to support national security,” Panzenhagen added. [emphasis mine]

In other words, the Space Force wanted to split this contract between the three companies, but it decided to give it all to SpaceX because it expected any launches given to ULA and Blue Origin would not launch on time, and it didn’t want “to leave [that] capability on the ground.”

In the case of ULA, its Vulcan rocket finally made its first two launches this year, four years late, but on the second launch had a failure on one of its solid-fueled strap-on boosters (the nozzle fell off). Though the rocket successfully placed its dummy payload into the correct orbit, the military has either decided that it can’t yet certify Vulcan for military launches, or sees further delays while the investigation and fixes are installed.

As for Blue Origin, its New Glenn rocket is also four years behind schedule, and likely won’t launch until next year. To get it certified will also probably require two launches, and since that company never seems to be in a hurry to do anything (NASA removed its payload from New Glenn’s first launch because the company had failed to meet the required interplanetary launch window), the Pentagon probably decided it can’t give it any contracts at this time.

And so, more launches and profits for SpaceX. While it is great for that company, with revenue that will likely aid in developing Starship/Superheavy, this is not a healthy situation for the American space industry. As a nation we need more than one launch provider. We need these other companies to stop dithering around and get the job done. That’s the true American way. Have they forgotten how to do it?

A different kind of chaos on Mars

A different kind of chaos on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on June 23, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). I had originally chosen to feature a different picture of this spot, taken on August 1, 2024 in order to create a stereo pair, but this week the camera team featured this first photo, providing a caption.

This disrupted surface is characterized by a collection of rounded to flat-topped mounds of various sizes connected by narrow flat floors, typical of the aptly named “chaotic terrain” on Mars.

What could have caused this flat surface to break into pieces? You might imagine that a flat surface could be broken up if it was inflated or collapsed. One hypothesis is that large amounts of water were released from deep below the ground to cause the surface break up.

Normally on Mars, especially in the mid-latitudes, chaotic terrain is associated with glacial activity, suggesting that glaciers over time erode valleys along random criss-crossing fault lines to create the mesas and canyons. This patch of chaotic terrain however suggests a different formation process.

GAO: Next SLS Artemis launches will almost certainly be delayed

10:52 am

SLS's two mobile launchers, costing $1 billion
NASA’s bloated SLS mobile launchers

According to a new Government Accountability Office (GAO) report released yesterday, NASA’S continuing delays and technical problems building the various ground systems required for the next few Artemis launches will almost certainly cause those launches to be delayed.

The schedule at present is as follows:

  • September 2025: Artemis-2 will be the program’s first manned mission, taking four astranauts around the Moon.
  • September 2026: Artemis-3 will complete the first manned lunar landing.
  • September 2028: Artemis-4 will send four astronauts to the Lunar Gateway station in orbit around the Moon, and then complete the second manned lunar landing.

The GAO report notes at length that modifications to the mobile launch platform SLS will use on the first two missions is taking longer than planned. It also notes that the problems completing the second mobile launcher continue, with the budget growing from $383 million to $1.1 billion, and the work years behind schedule with no certainty it will be completed in time for the 2028 mission. These issues are the same ones noted by NASA’s inspector general in August 2024.

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry,
including “cavities resulting from the loss of large chunks”

This report focused exclusively on the scheduling delays for the ground systems that will be used by SLS for each launch. It did not address the serious questions that remain concerning the serious heat shield damage experienced by the Orion capsule when it returned to Earth on its first unmanned mission in late 2022. NASA has been studying that problem now for two years, and as yet has not revealed a solution.

I continue to predict that the first manned landing, now scheduled for 2026, will not occur before 2030, six years behind the schedule first proposed by President Trump but actually fifteen years behind the schedule initially proposed by President George Bush Jr in 2004. All in all, it will take NASA almost a third of a century to put American astronauts back on the Moon, assuming the landing occurs in 2030 as I now predict. Compare that with the development time of SpaceX’s Starship/Superheavy. Proposed in 2017, it is already flying, and will almost certainly complete its first private manned lunar mission and its first test missions to Mars by 2027. The contrast is striking.

More and more the entire part of Artemis run by NASA is proving to be the failed disaster I predicted it would be in 2011. No wonder former New York mayor Michael Bloomberg wrote an op-ed yesterday calling for its cancellation. Like most politicians, reality is finally percolating into his thick skull, though several decades late.

Commerce loosens regulations, allowing American space companies easier use of international facilities

9:42 am

The Commerce department today announced that it has issued three new rulings that will ease the regulations and licensing procedures that American rocket and satellite companies have to go through in order to launch from international facilities.

The first rule will ease licensing for launches from Australia, Canada, and the United Kingdom. This will make it easier for American rocket companies to launch from the new spaceports being built in these nations, as well as allow satellite and orbital tug companies to launch their spacecraft from these nations using non-American rockets.

The second rule, still in its interim stage of approval, would ease the export licensing for satellites and spacecraft “to over 40 allies and partners worldwide, reducing licensing requirements for the least sensitive components for most destinations, and broadening license exceptions to support additional National Aeronautics and Space Administration (NASA) cooperative programs.” It appears this ruling focuses specifically on the countries who have signed the Artemis Accords, joining NASA’s Artemis program.

The third rule, which is at present only proposed, will remove from the State Department’s strict ITAR regulations many space-related defense technology, transfering their licensing to the much more relaxed Commerce department. This ruling appears aimed at helping the new burgeoning orbital tug, refueling, and satellite servicing industry, which uses rendezvous and proximity technology that was previously considered military in nature.

While it appears this easing of regulation goes against the Biden administration general policy of tightening regulations, the changes make sense if we recognize that these regulations also loosen access to American technology for many international partners, something this administration favors.

All in all, however, the changes are thoughtfully worked out, and will likely help energize the American space industry without releasing important technology to the wrong nations.

ESA awards OHB Italia a preliminary contract to build Ramses probe to Apophis

The European Space Agency (ESA) yesterday awarded the company OHB Italia a €63 million preliminary contract to begin work on mission dubbed Ramses that will launch in 2028 and rendezvous with the potentially dangerous asteroid Apophis when it flies past the Earth on April 13, 2029 at a distance of less than 20,000 miles.

The contract award is preliminary because the entire project still has to be approved by the ESA ministral council of nations, meeting in 2025. Because of the short development time, however, ESA’s management found funds from its existing budget to begin work.

To speed work, the project is also using as its design basis the Hera asteroid spacecraft, which was recently launched to study the binary asteroids Didymos-Dimorphos. That mission was also built remarkably fast for a European space project, going from contract to launch in just four years.

NASA has already re-tasked its OSIRIS-REx asteroid mission to head for Apophis, renaming it OSIRIS-APEX for reasons that baffle me. The mission had successfully delivered samples from the asteroid Bennu, but after completing that mission had sufficient fuel and was well placed to do this additional rendezvous as well.

ULA recovers nozzle debris that fell off during second Vulcan launch

9:05 am

ULA has recovered some of the debris that fell to earth after the nozzle on one of Vulcan’s two solid-fueled strap-on boosters fell off during the early stages of the rocket’s second launch on October 4, 2024.

Julie Arnold, a ULA spokesperson, confirmed to Ars that the company has retrieved some of the debris. “We recovered some small pieces of the GEM 63XL SRB nozzle that were liberated in the vicinity of the launch pad,” Arnold said. “The team is inspecting the hardware to aid in the investigation.”

The booster was built by Northrop Grumman. Vulcan can use from from two to six on each flight (in pairs), depending on the mass of its payload and the mission requirements. At the moment ULA has 35 of these boosters in storage awaiting future flights. It is expected that once the company has an idea of the root cause of the failure, it will have to inspect each booster to avoid a repeat of the problem.

Though ULA has not announced any changes in its plans to launch twice more before the end of the year, both for the Pentagon, that schedule is now uncertain due to this problem. For example, there as yet is no word on whether the military is willing to certify the launches. It had required ULA to complete two test flights of Vulcan before doing so, and the nozzle issue has cast a cloud on that plan.

  • NASA officials hint it might no longer maintain a continuous human presence in space after ISS
    They say this is because they are unsure the commercial stations will be ready for continuous occupation when ISS is retired. While that is likely a factor, a more important factor is NASA itself. When those commercial stations are flying private customers, NASA’s presence — which for decades has accomplished far less than it should have — will become increasingly irrelevant. A permanent human presence in orbit might not be continuous initially in the 2030s, but that gap won’t last long, as long as freedon and competition is allowed to flourish.
  • The countries who have signed the Artemis Accords are compaigning for new countries to join
    These comments were made by representatives from Estonia, Canada, Italy, Australia, and NASA. While expanding the alliance has advantages, the comments all indicate no interest in the accords’ initial purpose, to get around the limitations to private ownership imposed by the Outer Space Treaty. Instead, they seem focused on “building on the treaty,” a very bad sign for the future of capitalism and private enterprise in space.

    And to prove my analysis, NASA’s official even said that China could sign the accords if it wished. So much for defending freedom, capitalism, and private ownership.

Sinwar’s elimination is merely one small win in Israel’s new quest for total victory

Hamas vs Israel
The obvious reasons why killing the leaders
of Hamas and Hezbollah is a good thing.
Courtesy of Doug Ross.

The confirmation today that Israel had finally killed Hamas leader Yahha Sinwar, considered the main architect behind the October 7, 2023 murder, rape, and torture of more than a thousand Israeli men, women, children, and babies near Gaza is good news, but it only is one small victory in what is now clearly Israel’s decision to go for nothing less than total victory against the terrorists who have been hounding and killiing its citizens wantonly for decades.

You see, since the 1973 Yom Kippur war, all of Israel’s responses against terrorist groups like Hamas and Hezbollah have been limited and targeted, and ended quickly with fake ceasefires that allowed those terrorist groups to not only regroup, but actually expand their capabilities.

The most blatent and best example of this what happened in connection with Israel’s 2006 month-long invasion of Lebanon, launched in an attempt to defeat Hezbollah. The invasion bogged down, and as a result Israel and Hezbollah ended up agreeing to UN resolution 1701, which had Israel evaculate southern Lebanon and the UN take on the task of keeping the peace. The agreement also created a demilitarized zone in southern Lebanon, where Hezbollah was forbidden.

That agreement was an utter failure. Neither the UN nor Lebanon had the ability or even the desire to limit Hezbollah, and so before long it had made that demilitarized zone a launchpad for rocket attacks into Israel. In Israel’s most recent campaign to clear out that zone, it has also discovered tunnels and large weapons caches clearly designed for Hezbollah’s own planned October 7th-type invasion.

After October 7th, what I labeled Israel’s Pearl Harbor, Israel was clearly no longer going to accept this failed piecemeal and limited negotiating approach, administered by dishonest third parties like the UN and even the United States. Instead, it decided to go by an old American concept of “unconditional surrender,” first made plain by Grant during the Civil War and then underlined by Eisenhower and Roosevelt in their insistence on “total victory” in World War II.

In other words, Israel would only accept a ceasefire or peace treaty if it involved the surrender and capture of the leadership of Hamas and Hezbollah. If they refused to do this, then Israel resolved to kill them.

It has now demonstrated its ability to do so, with gratifying success.

Israel’s military actions since October 7th however also illustrate a major change in strategy and tactics. » Read more

A water sprinkler in space

A sprinkler in space

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a long term program to monitor changes in the R Aquarii binary star system, located about 700 light years away.

R Aquarii belongs to a class of double stars called symbiotic stars. The primary star is an aging red giant and its companion is a compact burned-out star known as a white dwarf. The red giant primary star is classified as a Mira variable that is over 400 times larger than our Sun. The bloated monster star pulsates, changes temperature, and varies in brightness by a factor of 750 times over a roughly 390-day period. At its peak the star is blinding at nearly 5,000 times our Sun’s brightness.

When the white dwarf star swings closest to the red giant along its 44-year orbital period, it gravitationally siphons off hydrogen gas. This material accumulates on the dwarf star’s surface until it undergoes spontaneous nuclear fusion, making that surface explode like a gigantic hydrogen bomb. After the outburst, the fueling cycle begins again.

This outburst ejects geyser-like filaments shooting out from the core, forming weird loops and trails as the plasma emerges in streamers. The plasma is twisted by the force of the explosion and channeled upwards and outwards by strong magnetic fields. The outflow appears to bend back on itself into a spiral pattern. The plasma is shooting into space over 1 million miles per hour – fast enough to travel from Earth to the Moon in 15 minutes! The filaments are glowing in visible light because they are energized by blistering radiation from the stellar duo.

The press release likens these filaments to the spray thrown out by a water sprinkler, and I must say that’s an apt description.

Since 2014 scientists have taken regular pictures of R Aquarii, and found that the central structures have been changing in a perceptible manner, despite their gigantic size. Below is a movie created from five photos taken from 2014 to 2023.
