Jupiter’s Great Red Spot appears to jiggle like Jello on a 90-day cycle

9:07 am

Jupiter as seen by Hubble over time
Click for original image.

Using the Hubble Space Telescope to photograph Jupiter’s Great Red Spot repeatedly over a four month period from December 2023 to March 2024 scientists have detected a 90-day cycle in which the spot oscillated in shape, shaking like Jello.

“While we knew its motion varies slightly in its longitude, we didn’t expect to see the size oscillate. As far as we know, it’s not been identified before,” said Amy Simon of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, lead author of the science paper published in The Planetary Science Journal. “This is really the first time we’ve had the proper imaging cadence of the GRS. With Hubble’s high resolution we can say that the GRS is definitively squeezing in and out at the same time as it moves faster and slower. That was very unexpected, and at present there are no hydrodynamic explanations.”

The four images to the right are some of those observations. For a full movie showing the changes over ninety days, go here.

The scientists also predict that though the spot has been shrinking for decades, they expect that shrinkage to stop once the spot size no longer extends beyond the jet stream band within which it sits. At that point the different jet streams in the upper and lower bands will hold the spot in place and its size will stabilize.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

The bad consequences to the bad COVID policies in 2020 continue to pile up

2:27 pm

Lysenko with Stalin
Trofim Lysenko (on the left), preaching to Stalin as he destroyed
Soviet plant research by persecuting anyone who disagreed with him,
thus causing famines that killed millions. He is now the role model for
today’s entire government health community.

Three stories this week illustrate once again that not only did none of the governmental actions imposed by our “betters” during the COVID panic in 2020 work, they are now resulting in long term harm across large populations.

First there was a study of 1.7 million children that found a marked increase in serious heart problems in children who got the jab.

Their research confirmed a large body of evidence showing links between the COVID-19 shots and myocarditis and pericarditis, particularly in adolescents. The research also confirmed that even in 2021, when the vaccine was first authorized for children and teens, that age group did not face a high risk for COVID-19-related serious outcomes, including death or the need for emergency care, hospitalization or critical care.

You can read the paper here [pdf]. Fortunately, the study also found no deaths in either group from these heart conditions, and that new heart ailments among the jabbed children were rare. Nonetheless, the study found solid evidence that the jab caused some harm while doing little to prevent COVID. As noted in the first link:

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.

Monitoring a changing spot on Mars

Monitoring a changing landscape on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on July 18, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Based on its label, “Dark Filamentary Streak Year-Round Monitor Site in Promethei Terra,” it was apparently taken as part of a long-term project to monitor the changes that occur at this particular spot on Mars.

This monitoring began in 2008, not long after MRO began science operations. In that first image, taken in the Martian autumn, almost the entire terrain was covered with dust devil tracks, all running more-or-less parallel to each other in a northwest-to-southeast direction.

That unusual tiger-striped landscape prompted later monitoring. However, a follow-up photo in 2010, also in autumn, showed practically no dust tracks here at all. Another image, taken in 2011 during the Martian summer, showed new dust devil tracks, but instead of being aligned as in 2008, the tracks went in all directions, with only a hint of alignment to the southeast.

Astronomers find another galaxy that shouldn’t be there in the early universe

9:44 am

REBELS-25
Click for original image.

The uncertainty of science: Using ground-based telescopes, astronomers have identified a galaxy only 700 million years after the Big Bang that is far more organized and coherent in shape and structure than thought possibly that soon after the theorized creation of the universe.

The galaxy in question is dubbed REBELS-25. It is at a red shift of z=7.31, which means that it is from a time when the universe was only 700 million years old. The earliest galaxies ever seen are only a few hundred million years older.

REBELS by name rebel by nature. This odd galaxy has stumped astronomers because it shows evidence of an ordered structure and rotation. It may even have a central elongated bar and spiral arms, though further observation is needed to confirm these structures.

This is in contrast to the small, messy, lumpy and chaotic norm for galaxies of a similar age. “According to our understanding of galaxy formation, we expect most early galaxies to be small and messy looking,” says co-author Jacqueline Hodge, an astronomer at Leiden University in the Netherlands.

You can read the published paper here [pdf]. The picture to the right shows this galaxy as seen by the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.

The consensus view of the early universe said there would not have been enough time for such a structured galaxy to form. And yet as astronomers use the improved astronomical instrumentation of our time to look deeper and deeper at that early universe, they keep finding things — like this galaxy — that defy that consensus view.

The answer to this mystery remains unknown, and is likely not yet answerable with the data we presently have. The data we do have however is beginning to suggest that scientists might have to begin looking at fundamentally different theories as to the inital formation of the universe. The Big Bang might still work, but if so it might require a major rewrite.

Donations to Columbia University continue to plunge in response to the pro-Hamas anti-Semitic protests on campus

2:13 pm

Columbia University's seal
The motto means “In Your Light [God],
We Shall See the Light.” Too bad no one
running Columbia now believes in this.

During an annual fundraiser event this week at Columbia University, donations plunged nearly 29 percent from its last event in 2022.

Columbia’s “Giving Day” event in 2024 raised $21.4 million, a significant decrease from the $30 million it garnered in 2022, according to the Columbia Spectator, the campus newspaper. The event was not held in 2023 due to the October 7 Hamas attack on Israel and the subsequent protests on campus.

The university also saw a nearly 28 percent decline in the number of gifts, which dropped from 19,229 in 2022 to 13,870 in 2024, the lowest level since 2015 and the first time the total monetary amount of the donations declined from the previous year since the event began in 2012. In response to the decline, the Columbia Spectator stated that the university is currently facing a “donor crisis — born out of concerns regarding campus protests.”

Curiosity’s upcoming travel route

12:36 pm

Curiosity's upcoming route
Click for original image.

Overview map
Click for interactive map.

Cool image time! The panorama above, cropped and annotated to post here, was taken on October 6, 2024 by the right navigation camera on the Mars rover Curiosity. It looks south, down the slopes of Mount Sharp and across Gale Crater, the distant crater rim barely visible through the dusty air twenty to thirty miles away.

The overview map to the right provide the context. The blue dot marks Curiosity’s present position. The yellow lines the approximate area covered by the panorama. The red dotted line indicates the rover’s planned route, with the white dotted line the path it has recently traveled.

As you can see, the rover has moved up onto a higher terrace surrounding the Texoli butte, and will now travel downhill a bit to skirt around its northern nose. From there, the science team plans to send the rover westward, traversing along the contour lines on the side of Mount Sharp. Along the way it will lose more elevation, but eventually, after passing several parallel north-south trending canyons, it will finally turn south into one canyon to resume its climb up the mountain.

To review the rover’s journey, Curiosity during its dozen years on Mars has traveled just over 20 miles and climbed about 2,500 feet. The peak of Mount Sharp however is still about 26 miles away and about 16,000 feet higher. Getting there will probably take at least three more decades, which is possible since the rover uses a nuclear power source similar to that used by the two Voyager interplanetary probes, now functioning in space for almost a half century.

In fact, it would not surprise me if the first human Mars colonies are established while Curiosity is still working, and that in its later years it sends its data to that colony directly (via an orbiting relay satellite), rather than beaming it back to Earth.

Scientists: both liquid water and ice shaped Gale Crater

9:38 am

The uncertainty of science: Using isotope data from instruments on the Mars rover Curiosity, scientists have found evidence that suggests that both liquid water as well as glacial ice helped shape the present geology in Gale Crater.

The paper proposes two formation mechanisms for carbonates found at Gale. In the first scenario, carbonates are formed through a series of wet-dry cycles within Gale crater [involving intermittent liquid water]. In the second, carbonates are formed in very salty water under cold, ice-forming (cryogenic) conditions in Gale crater [involving glacial ice].

“These formation mechanisms represent two different climate regimes that may present different habitability scenarios,” said Jennifer Stern of NASA Goddard, a co-author of the paper. “Wet-dry cycling would indicate alternation between more-habitable and less-habitable environments, while cryogenic temperatures in the mid-latitudes of Mars would indicate a less-habitable environment where most water is locked up in ice and not available for chemistry or biology, and what is there is extremely salty and unpleasant for life.”

…The heavy isotope values in the Martian carbonates are significantly higher than what’s seen on Earth for carbonate minerals and are the heaviest carbon and oxygen isotope values recorded for any Mars materials. In fact, according to the team, both the wet-dry and the cold-salty climates are required to form carbonates that are so enriched in heavy carbon and oxygen.

What I glean from this report is that the evidence that ice played the dominant role continues to build, but since it counters the liquid water theories that scientists have favored for decades they are reluctant to shift entirely to it. It also suggests the geological processes on Mars were far more complex than proposed (no surprise!), and that some mixture of both processes was likely.

This paper is of course merely a newly proposed hypothesis, and therefore its conclusions should be considered only with great skepticism.

More details revealed of computer hacking of Japan’s space agency last year

9:24 am

According to a news article yesterday, the hacking of the computer systems of Japan’s space agency JAXA last year was far more extensive than first revealed, involving multiple attacks that obtained a great deal of data from many third parties, both governmental and commercial, and included the takeover of the accounts of five of JAXA’s nine-member board.

In the first attack, hackers stole the personal data of about 5,000 employees of JAXA and its related companies—nearly everyone with personal data on the computer network at the time. A JAXA investigation found that hackers took over accounts of about 200 of those individuals, including many senior JAXA officials, and gained unauthorized access to information, the sources said. The 200 hijacked accounts included those of about five directors on the nine-member board at the time, including President Hiroshi Yamakawa, the sources said. Hackers apparently targeted the accounts of directors and other senior officials who are authorized to access information on JAXA’s negotiations with outside parties, the sources said.

…According to the in-house investigation, Microsoft Corp.’s cloud service Microsoft 365 was compromised in the June 2023 cyberattack. More than 10,000 files of information stored on Microsoft 365 could have been leaked, the sources said. Of those, more than 1,000 files were provided by outside parties, including more than 40 companies and organizations with which JAXA had concluded non-disclosure agreements. Thse 40-plus entities include NASA, the European Space Agency, Toyota Motor Corp., Mitsubishi Heavy Industries Ltd. and the Defense Agency.

The source of the attacks was not indicated, but based on past hacks both of JPL and JAXA, China is the prime suspect. That country has routinely worked to steal technology from others. We should therefore not be surprised if Chinese space designs continue to resemble western concepts, down to the smallest nails.

SpaceX says it is targeting October 13, 2024 for 5th Starship/Superheavy launch

9:13 am

Superheavy being captured by the tower chopsticks at landing
Artist rendering of Superheavy being captured by
the tower chopsticks at landing. Click for video.

The hint last week that SpaceX might attempt its fifth test orbital launch of Starship/Superheavy launch by mid-October was confirmed yesterday by the company. It announced on its Starship/Superheavy webpage that it is now targeting October 13, 2024 for 5th Starship/Superheavy launch, “pending regulatory approval.”

SpaceX’s announcement noted that the flight’s primary goals will be an attempted chopstick landing of Superheavy at the launch tower in Boca Chica and a test of Starship’s ability to return and land using its newly redesigned heat shield.

The returning booster will slow down from supersonic speeds, resulting in audible sonic booms in the area around the landing zone. Generally, the only impact to those in the surrounding area of a sonic boom is the brief thunder-like noise with variables like weather and distance from the return site determining the magnitude experienced by observers.

Starship will fly a similar trajectory as the previous flight test with splashdown targeted in the Indian Ocean. » Read more

Dominican Republic signs the Artemis Accords

8:52 am

The Dominican Republic yesterday became the 44th nation to sign the Artemis Accords, original conceived by the Trump administration as bi-laterial agreements between the U.S. and other nations and focused on building a strong coalition for getting the Outer Space Treaty’s limitations on free enterprise and private property cancelled or overturned.

Sadly, under the Biden administration that focus has been pushed aside, replaced with watered-down “principles [that] support the safe and sustainable exploration of space” that are also “grounded in the Outer Space Treaty.”

In other words, nations signing the accords now are simply signing on in the hope of getting American cash by joining the American Artemis program. The full list of nations is as follows: Angola, Argentina, Armenia, Australia, Bahrain, Belgium, Brazil, Bulgaria, Canada, Colombia, Czech Republic, Dominican Republic, Ecuador, 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.

Whether this alliance can eventually be used as a tool to overturn the Outer Space Treaty’s restrictions on private property in space remains unknown. A new Trump administration would almost certainly shift things back in the right direction, especially if that administration reshaped the entire Artemis program away from its failed reliance on SLS, Orion, and Lunar Gateway and instead allowed private companies to redesign the program entirely, based on what makes the most economic and engineering sense rather than funding big government projects that accomplish litte except create make-work jobs.

FAA and the Biden administration proves it is out to destroy SpaceX

9:47 am

The FAA to SpaceX
The FAA to SpaceX “Nice company you got here.
Sure would be a shame if something happened to it.”

In the past week the FAA proved unequivocally that it is abusing its regulatory powers for political reasons, imposing much harsher regulatory restrictions on SpaceX while allowing other companies much more free rein.

That reality became most evident first with the FAA response to the serious failure of one of the strap-on solid-fueled boosters during the second test launch of ULA’s Vulcan rocket on October 4, 2024. During that launch something went seriously wrong with that booster 38 seconds after launch, involving an explosion and what appeared to be ejection of that booster’s nozzle. Though the launch succeeded in placing its payload into the correct orbit, it required the rocket’s main engines to compensate aggressively.

Despite this, the FAA decided no investigation by it was necessary.

The Federal Aviation Administration, which licenses commercial space launches in the United States, said in a statement that it assessed the booster anomaly and “determined no investigation is warranted at this time.” The FAA is not responsible for regulating launch vehicle anomalies unless they impact public safety.

This decision is correct, but the contrast with the FAA’s treatment of SpaceX is quite striking. If the FAA applied the absurd standard it has been using against SpaceX, it would claim that this Vulcan launch threatened public safety because the incident occurred 38 seconds after launch and was thus relatively close to Florida, where an out of control rocket could potentially threaten public safety.

Such a threat of course really doesn’t exist, as the FAA correctly concluded, because the rocket has a self-destruct system to prevent it from crashing in habitable areas.

Yet the agency failed to use this logic with SpaceX. Instead the FAA decided anything SpaceX launches that doesn’t work perfectly poses a serious public safety threat, no matter where or how it happens, and thus has repeatedly grounded SpaceX launches. A first stage, flown already 23 times, falls over after soft-landing successfully on its drone ship in the middle of the Atlantic, and somehow this justified the FAA grounding SpaceX due to the threat to public safety. A second stage, after successfully placing two astronauts into orbit, misfires during its de-orbit burn but still lands in the middle of the ocean, far from any habitable regions, and somehow this justified the FAA grounding SpaceX due to the threat to public safety.

And the fact that a Superheavy returning to its launchpad at Boca Chica will cause a sonic boom — as do every Falcon 9 landings at Cape Canaveral or Vandenberg — is now justification for grounding Starship/Superheavy test launches, even though sonic booms pose zero threat to anyone other than startling them with the sudden noise.

The FAA further illustrated its bias against SpaceX when it decided to allow the company to do its launch this morning of Europe’s Hera asteroid mission, but specifically stated that the company’s other launches remain grounded.

Spanish rocket startup PLD unveils a proposed family of rockets plus crew capsule

8:48 am

The Spanish rocket startup PLD this week unveiled a proposed family of rockets to follow its Miura-5 rocket, set to launch for the first time in 2025.

The three rockets introduced were the Miura Next, Miura Next Heavy, and Miura Next Super Heavy, all based on a system or modular building blocks. Miura Next will be the base of the modular system will be a single-stick two-stage rocket. Miura Next Heavy will feature two boosters and Miura Next Super Heavy will feature four boosters. The boosters will have a shared architecture with the rocket’s core stage. The first stages and boosters will all feature a propulsive recovery capability.

The smallest of the three rockets will be capable of delivering up to 13,580 kilograms to low Earth orbit, while the most powerful will have the capacity to deliver 53,000 kilograms.

This design concept essentially follows the approach that SpaceX used to develop the Falcon Heavy from the Falcon 9, and saves a great deal of money by using what the company has already developed as part of the larger rocket.

The crew capsule, dubbed Lince, is conceived at this company’s version of Dragon, capable of launching either cargo or 4 to 5 astronauts to any one of the proposed commercial space stations under construction. Capsule drop tests will begin in 2025, with the first launch abort tests in 2028 aiming for the first orbital flight by 2030.

SpaceX launches Europe’s Hera asteroid mission

8:41 am

SpaceX today successfully launched the European Space Agency’s (ESA) Hera asteroid mission to the binary asteroid Didymos and Dimorphos, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its 23rd rocket, but was not recovered in order to maximum the fuel used to send Hera on its proper route. The fairings completed their 13th and 19th flights respectively.

Hera will do a follow-up rendezvous with the binary asteroids to get a close-up look at the consequences of the Dart impact back in 2022 of Dimorphos.

The leaders in the 2024 launch race:

96 SpaceX
44 China
11 Russia
11 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 113 to 67, while SpaceX by itself now leads the entire world, including American companies, 96 to 84.

For SpaceX, this launch ties the record the company set last year for the number of launches of a private company in a single year, and it did so in just more than three-quarters of the year. The company’s goal of 144 launches in 2024 remains possible, assuming the federal government stopped blocking its operations. For example, the FAA granted the company permission for this one launch, but maintained its grounding of further launches because an upper stage did not land safely in the ocean in the exact right spot.

Frozen eddies at the confluence of two glacial rivers
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on July 3, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels the photo as capturing a “contact near Reull Vallis,” a 1,000-mile-long Martian canyon that flows down the eastern slopes of Hellas Basin, the death valley of Mars.

What I see isn’t a geological contact but a complex jumble of odd-shaped depressions and mesas, surrounded by an eroded surface that seems squashed and deformed by some process. If this is all we had to go on, I would simply label this as another “What the heck?” image on Mars and move on. However, the larger context of the overview map helps explain it all, at least as best as we can explain using orbital data.

NASA pushes discrimination to favor minorities in its education workshops

11:31 am

NASA: dedicated to segregation!
NASA: dedicated to the new segregation!

“Segregation today, segregation tomorrow, segregation forever!” A NASA press release today proudly touted what it called a “Culturally Inclusive Planetary Engagement in Colorado,” one of a series of recent science/education workships designed specifically to help “black and Latinx youth and their families.”

Though the events are apparently not segregated, it also appears that white and Asian kids and their parents were not really welcome.

Planetary scientists and engineers from Boulder, as well as scientists from Florida, Maryland, and Alaska participated. ReaCH partnered with the Boys & Girls Clubs of Metro Denver, whose staff participated in the workshop to share their perspectives. Other educators local to the Denver area also participated, along with an educational specialist from NASA@ My Library (another Science Activation program). The workshop culminated in an event at the Shopneck Boys & Girls Club in Brighton, CO; workshop participants facilitated a variety of hands-on planetary activities for approximately 120 children. Workshop participants also shared information about college pathways into science professions with teenagers at the Club.

The location and the local organizations were specifically chosen to aid these specific minorites above anyone else.

Sierra Space wins Air Force contract to develop orbital cargo delivery system

9:49 am

The Air Force has now awarded Sierra Space a contract to develop its proposed “Space Ghost” satellite spacecraft, designed to be launched into a stand-by orbit carrying needed cargo, where it can upon command deliver that cargo within 90 minutes anywhere on Earth.

Sierra Space won a contract of undisclosed value as part of the AFRL’s Rocket Experimentation for Global Agile Logistics (REGAL) program. The Air Force is exploring the potential of space vehicles to rapidly transport critical supplies from orbital warehouses back to Earth. This could include reusable reentry vehicles capable of delivering payloads from prepositioned stocks in orbit.

Sierra Space, based in Louisville, Colorado, said its defense technology team designed the Ghost system to be capable of remaining in orbit for up to five years, storing and delivering essential supplies on-demand. Once fully developed, the spacecraft could be used for missions such as delivering rescue kits for downed pilots, medical supplies for disaster relief or logistical support for military operations.

The company began doing drop tests of a Space Ghost prototype heat shield in March, and apparently the data satisfied the Air Force enough to issue this development contract. Whether such a system however makes sense remains unknown. To be able to deliver cargo anywhere on Earth will require putting up a large constellation of Space Ghost satellites, in many different orbits. Moreover, it is unclear how much cargo each satellite would carry.

Avio completes testing of new redesigned nozzle for its Vega-C second stage

9:31 am

The Italian rocket company Avio yesterday successfully completed the second of two static fire engine tests of the newly redesigned nozzle for the second stage of its Vega-C rocket, paving the way for the company to resume launches after the nozzle design failed both during a launch in 2022 and then again during a static fire test in 2023 after its first redesign.

A launch date has tentatively been scheduled for November, but this date is not yet confirmed. For this and the next several launches in 2025, the rocket will still be managed by the European Space Agency’s (ESA) commercial arm, Arianespace. Beginning late next year however Avio will regain complete control of its rocket and will be able to market it internationally, no longer required to deal with this unneeded government middleman. The launch price will then certainly go down, making Vega-C more competitive.

Engineers set new laser communications record to asteroid probe Psyche

9:16 am

Psyche-Earth laser communications record
Click for original graphic.

As part of a continuing test program, engineers have set a new long distance laser communications record, exceeding 290 million miles, by successfully using a laser to send communicate with the asteroid probe Psyche from Earth.

The graph to the right, not to scale, shows the orbital configuation of the laser record. It appears however that little actual data was sent in this last test. It merely demonstrated that a link could be established. An actual data transfer record by laser occurred in June.

On June 24, when Psyche was about 240 million miles (390 million kilometers) from Earth — more than 2½ times the distance between our planet and the Sun — the project achieved a sustained downlink data rate of 6.25 megabits per second, with a maximum rate of 8.3 megabits per second. While this rate is significantly lower than the experiment’s maximum, it is far higher than what a radio frequency communications system using comparable power can achieve over that distance.

The high data rates promised by laser communications will significantly improve deep space operations. Most especially, the ability to get data back in much larger packets more quickly will reduce the antenna bottleneck on Earth that limits the number of missions as well as the data can be returned daily. More missions will be able to fly, and scientists and engineers will get their results faster.

FAA: No Starship/Superheavy launch before late November

9:01 am

In response to speculation that the fifth Starship/Superheavy test launch could happen in mid-October — based on a recent notice to mariners from the Coast Guard, the FAA on Wednesday made it clear that its stonewalling of SpaceX will continue.

“We are not issuing launch authorization for a launch to occur in the next two weeks — it’s not happening,” an FAA spokesman said Wednesday afternoon. “Late November is still our target date.”

The report comes from the San-Antonio Express-News, and as is typical of the reporting in the propaganda press, the article only gives the FAA’s side of this story, making absolutely no mention of SpaceX’s detailed and very public objections. As far as this news outlet is concerned, the FAA is god, whatever it says must be true. So much for a skeptical free press whose goal is supposed to be to hold government accountable.

ULA this morning successfully completed the second test launch of its new Vulcan rocket, lifting off from Cape Canaveral from Florida.

It placed a dummy test payload into orbit in order to obtain from the Space Force certification that will allow the company to begin operational military launches and actually make money from the rocket. ULA hopes to launch two such Vulcan launches before the end of the year, and then hopes to do ten more Vulcan launches in 2025, along with ten Atlas-5 launches as it closes out that rocket’s inventory before retiring it.

UPDATE: An explosion on of Vulcun’s two solid-fueled strap-on boosters during the launch today might prevent a quick certification from the military. Though the rocket successfully put the payload into its correct orbit, it appears the nozzle failed on that booster, throwing it out sideways, fortunately away from the rocket. The video here shows this clearly. I was startled by this explosion during the launch, but then forgot about it (until my readers reminded me) when the payload reached orbit as planned.

The strap-on boosters are manufactured by Northrop Grumman. Before using them again ULA needs to get clarity on this issue. We also must wonder if the FAA will step in as it has for SpaceX to ground ULA. At the moment it has decided not to do so.

This was ULA’s fifth launch in 2024, so there is no change in the 2024 launch race leader board.

95 SpaceX
44 China
11 Russia
11 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 112 to 67, while SpaceX by itself now leads the entire world, including American companies, 95 to 84.

An evening pause: Its an “official video,” so much of this is lip synched footage cobbled together to make what looks like a single performance. Much of it however is the actual performance, and the song is good.

Hat tip James Street.

    As Jay notes, “Regular news outlets are picking this up with the usual apocalypse chatter.” The big issue is how this might effect emergency communications using ham radio.
