Florida proves that too many professors at public colleges might be better employed as dish washers
As noted by the Spirit of Christmas Present in Dickens’ The Christmas
Carol, “This boy is ignorance, this girl is want. Beware them both,
but most of all beware this boy.” It appears Florida has taken this
warning to heart. Click for movie.
Last year the Republican-controlled state government in Florida passed legislation requiring its public universities to do what are called “post-tenure reviews” on all their tenured professors every five years, as part of an effort to eliminate what Governor Ron DeSantis called “deadweight” and “unproductive tenured faculty.” The bill not only limited the ability of professors to protest termination decisions, it was also aimed at eliminating “diversity, equity, and inclusion” programs across the board.
At the University of Florida the first round of tenure review has now produced some startling numbers, literally proving DeSantis’ claims.
The report said that, out of 262 professors up for review, 31 “either retired, entered retirement agreements or resigned during the review period.” A further 34 didn’t meet expectations and five were dubbed unsatisfactory. Add those categories up, and it’s 27 percent.
In other words, when faced with a real review of their qualifications, more than a quarter of the professors either quit or were removed. Though it is unclear whether those who quit did so because they knew they’d be fired anyway, that conclusion is a reasonable one to make. By resigning, they avoid having a stain on their record and thus increase their chances of getting work elsewhere.

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
Archeology on ISS?
Archeologists have now published a paper outlining what they call the first archeology project in space, documenting the changes that have occurred at six different locations on the International Space Station during a 60 day period.
[The archeologists] had the astronauts use adhesive tape to define one-meter areas of the International Space Station and document them with daily photographs to study how the spaces were used over 60 days in 2022. The squares were placed in a handful of work and leisure locations on the space station, including the U.S. galley table, workstations, experimental EXPRESS racks and on the wall across from the latrine where astronauts kept their toiletries.
The team’s findings provide the first glimpse into how astronauts adapt to life and conduct research without gravity, how international cooperation plays out in the tight quarters, how they use their space for work and leisure while in orbit, and more. By cross-referencing the photos with astronaut activity reports, the researchers found that the area near the exercise equipment and latrine, while not designated for any particular purpose, had been used as storage for toiletries, resealable bags, and a rarely used computer. The equipment maintenance area was actually used for storage, with little maintenance carried out there. [emphasis mine]
This research has some value, but on the whole its substance I think is overrated. When you build a home, the rooms have generally accepted purposes (kitchen, bathroom, bedroom, office, living room) but with some of those rooms it is expected that the homeowners will bring their own needs and desires to the place and use them as they please. The study above demonstrates this perfectly with the highlighted sentence. Though one area was designed to be a repair workbench, the astronauts found it more convenient or necessary to all such work elsewhere, and repurposed the maintenance area more practically.
At the same time, neither a space station nor an interplanetary spaceship are like homes. Both are actually entire worlds packed into a small space, so a lot of thinking has to go into designing them. It is in this area this research has some value. We are still learning what “rooms” will generally be needed in such long term space vessels, and this study can provide some data for this purpose.
Even so, I remain skeptical. It will likely be much cheaper and faster to simply talk to the astronauts who have lived on ISS to get their imput on how the interior space of a future interplanetary spaceship or station should be designed. In fact, the best thing to do would be to hire astronauts to help with the design process. That’s what the Soviets did in designing Soyuz. Asking archeologists for this information is nice, but seems very distant from the real issue. And it creates work on the station that might be better used doing something else.

Scientists propose much more efficient method for warming Mars to habitable temperatures
Global map of known exposed scarps of ice on Mars. North and south of the
white hatched lines, near surface ice and glaciers are common.
Scientists have now proposed much more efficient method for warming the climate of the planet Mars by as much 50 degrees Fahrenheit, enough to melt much of the near-surface ice in the middle latitudes and thus make the planet habitable.
This new method, using engineered dust particles released to the atmosphere, could potentially warm the Red Planet by more than 50 degrees Fahrenheit, to temperatures suitable for microbial life—a crucial first step towards making Mars habitable.
The proposed method is over 5,000 times more efficient than previous schemes to globally warm Mars, representing a significant leap forward in our ability to modify the Martian environment. What sets this approach apart is its use of resources readily available on Mars, making it far more feasible than earlier proposals that relied on importing materials from Earth or mining rare Martian resources.

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.

PLD targets October to begin construction of launch facilities in French Guiana
The Spanish rocket startup PLD is now targeting October to begin construction of its launch facilities in French Guiana, using the long abandoned launch site of France’s first rocket.
PLD Space plans to start building launch facilities for its Miura 5 rocket in October from the Diamant site at Guiana Space Centre, cofounder and chief business development officer Raúl Verdú told SpaceNews. Diamant has been dormant for decades after once being used for the French rocket of the same name, and “in the area where we are there is nothing,” Verdú said, “we have to do everything from scratch.”
The company hopes to do its first orbital launch in 2025.
Control of the French Guiana spaceport reverted back from Arianespace to the French space agency CNES (which has always owned it) in 2022, and since then CNES has signed deals with seven European rocket startups. PLD appears to be moving the fastest towards the first private commerical launch there.

Brooklyn startup wins NASA contract to develop wireless communication technology for use on the Moon
The Brooklyn startup Yank Technologies has won a $150K NASA contract to develop wireless communication technology for use on the Moon.
Yank Technologies plans to develop two systems for the lunar surface: Wireless Power Receiver Converters for lunar rovers and Resonant Inductive Connectors for high voltage power transmission on the Moon and Mars.
The Wireless Power Receiver Converters are designed to improve rover efficiency and reduce mass by integrating multiple converters into a single-stage converter that supports various voltages. These converters also enhance charging reliability by accommodating misalignment and varying distances.
Resonant Inductive Connectors are designed to maintain reliable connections with high-voltage lines despite the presence of lunar regolith or Martian dust. Unlike traditional connectors, which are prone to wear and unreliable connections, these connectors are built to withstand harsh environments.
The award was likely made in late June as part of an small business award of similar development contracts to about 250 companies. Though wireless techology is well established, in this case the goal is to lower the weight of this equipment while making it space-hardened. While such work is routinely required, this contract highlights the detail work necessary for making operations on an alien planet practical.

Rocket Factory Augsburg completes 2nd static fire test of first stage
The German startup Rocket Factory Augsburg has apparently completed a second static fire test of the first stage of its RFA-1 rocket.
The test occurred on the launchpad the company will use to launch at the Saxaford spaceport in the Shetland Islands. Video of the test is available here.
The test itself lasted for approximately 15 seconds and included five of the company’s Helix rocket engines. While this is one more than the previous test, it’s still short of the full nine-engine complement that will be utilized aboard every RFA ONE first stage.
A full static fire test of all nine engines is still necessary before launch. The rocket’s upper stage has already completed its full test compaign and is on the way to Saxaford for stacking.
The hope is that the first orbital test launch will occur before the end of the year, but for that to happen Rocket Factory must get its launch license from the UK’s Civil Aviation Authority (CAA). Based on how slow it approved its only previous launch license for Virgin Orbit (bankrupting the company because it took so long), no one should be expect a launch this year.

Chinese Long March 6A upper stage breaks up into debris shortly after deploying satellites
Ground and satellite reconnaissance data now indicates that the upper stage of the Chinese Long March 6A rocket that on August 6 launched the 18 satellites in a proposed Chinese 14,000 satellite internet constellation broke up into numerous pieces shortly after deploying the satellites.
The detection was made by the company Slingshot Aerospace, which tracks orbital spacecraft looking for the appearance of this kind of space junk.
This is actually the second time recently that an upper stage of a Long March 6A has broken up shortly after launch. In December 2022 the same thing was detected following a November launch.
All told, this relatively new Chinese rocket has launched seven times, and has had its upper stage break up twice. Apparently, China not only doesn’t care if the lower stages of its many rockets crash on top of its own citizens, it is quite okay with littering near-earth orbital space with debris. It needs to fix the upper stage of this rocket now, so such break-ups no longer occur.

Gaia space telescope identifies more than 350 asteroids with candidate moons
Using the Gaia space telescope, astronomers have identified 352 asteroids that the data suggests have smaller satellite asteroids in orbit around them.
In its data release 3, Gaia precisely pinpointed the positions and motions of 150 000+ asteroids — so precisely that scientists could dig deeper and hunt for asteroids displaying the characteristic ‘wobble’ caused by the tug of an orbiting companion (the same mechanism as displayed here for a binary star). Gaia also gathered data on asteroid chemistry, compiling the largest ever collection of asteroid ‘reflectance spectra’ (light curves that reveal an object’s colour and composition).
These results need to be confirmed by direct observation, as this method does involve some assumptions and uncertainties. If these numbers are confirmed however it will give planetary scientists a better census on the percentage of asteroids with moons, which in turn can be used to create better models of the formation of the solar system as well as the evolution of asteroids over time. At the moment scientists predict about one out of every six asteroids will have a moon. This data suggests that number might be high.

SpaceX sets August 26, 2024 as new launch date for Polaris Dawn private manned mission
Jared Isaacman
According to a post on X yesterday, SpaceX has rescheduled the launch of the private Polaris Dawn manned orbital flight to August 26, 2024. The flight is financed entirely by billionaire Jared Isaacman, who will also command the mission (his second in space).
The mission will launch on a Falcon 9, with the Dragon Resilience spacecraft carrying four private astronauts. During the orbital flight the capsule will attempt to fly as high as 870 miles, the highest any human will have flown since the Apollo missions. It will then attempt the first spacewalks by a private citizen ever. They will open a hatch, and Isaacman will push himself outside.
The schedule change from July 31st is almost certainly due to the uncertainties surrounding the return of Starliner from ISS, which have also caused uncertainties in the launch date of SpaceX’s next manned mission to ISS. With only two launchpads in Florida for both missions (plus other required launches), a lot of juggling has been required.

- Outpost Space touts its proposed re-entry system for orbital spacecraft
The animation shows a variation of the system ULA eventually wants to use to recover the first stage engines on its Vulcan rocket.
- ULA’s CEO touts the number of Atlas-5 stages stacked in their warehouse, waiting launch
These are simply the last Atlas-5s before the rocket is retired.
- Another relatively boring press release of an image from Europe’s Mars Expresss orbiter
I post so few images from Mars Express because Europe releases so few, and when they do, they don’t usually provide enough good information to understand what one is looking at. For example, this release never really tells us the global location of the picture, info that is crucial to understanding it. I could look it up, but the image itself is just not that interesting.
- Blue Origin touts a short 5-second video showing a test firing of the attitude thrusters on New Glenn’s first stage
It is unclear if the video shows an actual first stage, or simply a mock-up for mounting the thrusters. Blue Origin was targeting September 29th for the first New Glenn launch, but based on the present status, that’s increasinly appearing unlikely.
- Roscosmos lost 17 billion ruble in 2022 (better than predicted) and 14 billion in 2023
It blames the losses on the actions of “unfriendly” countries, which is a hoot because it was Russia’s uncalled for invasion of the Ukraine that made it a pariah. If anyone demonstrated unfriendliness, it was Russia.

Students win settlement against college for censoring their speech illegally
One of the posters that Clovis Community College officials agreed to
“gladly” remove because it made some students “very uncomfortable.”
Bring a gun to a knife fight: Back in November 2021 three students at Clovis Community College who were also members of the college club for Young Americans for Freedom (YAF) got permission to put up posters on campus showing in detail the historic and documented horrors of communist rule worldwide. The picture to the right shows one such poster.
Soon thereafter some people supposedly complained that the posters made them “uncomfortable.” Despite the fact that everything in the posters is factually true, the then college president Lori Bennett ordered the posters torn down, claiming she did it because they weren’t specifically a “club announcement.
In August 2022 the students sued [pdf] with the help of the Foundation for Individual Rights and Expression (FIRE), noting that Bennett’s policy was not only inconsistent and arbitrarily, it was mostly used to block conservative political statements college administrators did not like.
The students have now won a settlement in court.

Another “what the heck?” image from Mars
Click for original image.
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on April 14, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what the scientists simply label as “exposed crater floor materials.”
I label it as another one of my “what the heck?” images, showing features that in some ways defy understanding or explanation. The picture shows a small area of the floor of an unnamed 14-mile-wide crater, with its rim indicated. Though clearly visible in orbital photos, the crater is nonetheless heavily eroded and even appears partly buried, possibly by flood lava.
The complex floor features however are not anything usually seen in flood lava terrains. The terrain colored blue in the color strip likely indicates coarse material like sand or rocks or rough bedrock, while the reddish terrain suggests the surface is heavily coated with dust.

Firefly wins a 20-launch contract from L3Harris
The rocket startup Firefly has been awarded a new 20-launch contract from the aerospace company L3Harris, and is an add-on to an earlier three-launch contract signed in 2023.
The deal calls for two to four launches per year beginning in 2027. The launches will take place at Firefly’s launchpad at Vandenberg in California, and will likely be for mostly military or surveillance payloads.
It appears that Firefly is beginning to grab business from both SpaceX and Rocket Lab, a very healthy development. Its rocket’s capabilities falls somewhere in between both, so it has developed its own customer niche.
All will change of course when Rocket Lab’s larger Neutron rocket becomes operational.

NASA has decided to consider bringing Starliner down unmanned
Starliner docked to ISS.
It appears that upper management at NASA has decided to force the agency to consider bringing Starliner down unmanned and extending the ISS mission of the two Starliner astronauts to a nine month mission.
The situation is definitely complicated, and no change as yet as been made. The schedule of dockings to ISS has been reconfigured to make this option possible. It appears this is the present plan:
First, they need to upgrade the software on Starliner for an unmanned mission. Apparently the present software on board is not satisfactory for an unmanned docking, even though a different Starliner has already done an unmanned docking last year. For this mission, the software relied on the astronauts to take over manually should there be an issue during undocking. In the previous unmanned demo, the software would react and prevent a problem. For reasons that make no sense, the software on the manned mission did not have this capability. Reinstalling this software will give them the option to send the two astronauts down on Dragon and returning Starliner unmanned.
Second, the next Dragon manned mission has been delayed until late September to allow time for these software upgrades, as well as give NASA and Boeing more time to analyze the situation and decide if a manned return on Starliner is possible. If they decide to not use Starliner, the Dragon capsule would come up to ISS with only two astronauts, and the two Starliner astronauts would then join them on their six month mission, coming home in the spring. For the Starliner astronauts Butch Wilmore and Suni Williams this would mean their mission will now be 8-9 months long, far longer than the original one-two week mission.
As to why these options are now being considered, it appears to me that both Boeing and NASA engineers were willing to return the astronauts on Starliner, but have been ordered to consider these options by higher ups. It appears that the last hot-fire thruster tests on ISS left everyone with some uncertainties about the situation. Engineers are fairly certain that the reasons some thrusters did not fire as planned during docking was because teflon seals expanded because of heat to block fuel flow. The problem is that these seals showed no problem at all in the most recent test on ISS. That difference creates some uncertainty as to whether they have really identified the cause of the problem. Imagine having an intermittent problem your car mechanic cannot constently make happen.
Because the thrusters did work as intended, Boeing and NASA seemed ready to return Starliner manned. In the agency review last week it appears others at the top were less sanguine (including Bill Nelson, NASA’s administrator), and demanded these new options be considered. Based on this speculation, it is almost certain Starliner will come home empty.
Whether this will have significant consequences remains uncertain. During the press briefing today, NASA officials said the agency might still certify Starliner for operational manned missions even if the capsule comes home unmanned.
Starliner docked to ISS.
It appears that upper management at NASA has decided to force the agency to consider bringing Starliner down unmanned and extending the ISS mission of the two Starliner astronauts to a nine month mission.
The situation is definitely complicated, and no change as yet as been made. The schedule of dockings to ISS has been reconfigured to make this option possible. It appears this is the present plan:
First, they need to upgrade the software on Starliner for an unmanned mission. Apparently the present software on board is not satisfactory for an unmanned docking, even though a different Starliner has already done an unmanned docking last year. For this mission, the software relied on the astronauts to take over manually should there be an issue during undocking. In the previous unmanned demo, the software would react and prevent a problem. For reasons that make no sense, the software on the manned mission did not have this capability. Reinstalling this software will give them the option to send the two astronauts down on Dragon and returning Starliner unmanned.

A supernova overpowers a spiral galaxy
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken in early 2023 by the Hubble Space Telescope because a ground-based automated sky survey had detected a new supernovae in late 2022 in this galaxy. The spiral galaxy is dubbed LEDA 857074, and is interesting because of its bright central bar and dim and broken spiral arms.
That supernova is the bright spot inside the galaxy’s central bar. It is so bright that it almost looks like someone accidently pasted a white dot there using a graphics program. From the caption:
Astronomers have catalogued millions of galaxies, so while today tens of thousands of supernovae are detected annually, the chance that one is spotted in any particular galaxy is slim. We also do not know how actively LEDA 857074 is forming stars, and therefore how often it might host a supernova. This galaxy is therefore an unlikely and lucky target of Hubble, thanks to this supernova shining a spotlight on it! It now joins the ranks of many more famous celestial objects, with its own Hubble image.
The galaxy itself had been studied by almost no one until this supernova was discovered in it.

Orbital tug startup Impulse Space increases the kinds of satellites it will offer rides to geosynchronous orbit
The orbital tug startup Impulse Space, founder by former SpaceX engineer Tom Mueller, has announced new plans to make it possible for its tugs to take more kinds of satellites to geosynchronous orbit.
First, the company is revising the design of its larger Helios tug, set to do its first commercial mission in 2027, to carry multiple satellites ranging in weight from 300 to 5000 kilograms. Second, it is upgrading its already-flown smaller Mira tug so that it can be attached to Helios and act as a secondary tug once Helios gets to geosynchronous orbit.
The first Mira demo mission, launched in November 2023, had some communications and software issues but was still considered an overall success. The next mission will fly later this year.

European aerospace company Safran to open production facility in U.S.
The European aerospace company Safran, which presently partners with Airbus to build the Ariane-6 rocket, has announced that it will open a production facility in Colorado for manufacturing its electrical propulsion thrusters used by satellites.
The American facility will focus on U.S. government and commercial customers, with the French line focusing on customers in the rest of the world. “With this double manufacturing line, we are able to provide trust and confidence to both U.S. domestic, national programs as well as commercial programs,” he said.
The thrusters produced by the two lines will be identical other than the sourcing of components for its power processing unit. The units produced in the United States will use U.S. components while those made in France will use foreign components.
The thruster, called the EPS X00, or “X-hundred”, is a new design and is expected to launch on satellites beginning in 2026. This announcement lets American companies know it is available to them as well. Being built in the U.S. it avoids the strict State Department ITAR regulations that would make it difficult for Safran to sell its European-built thrusters to American satellite companies.

Axiom changes its CEO

After founding and leading Axiom for the past eight years, CEO Mike Suffredini, has decided to transfer to the company’s board of directors and pass the company’s leadership to someone else.
“I have dedicated over 40 years to advancing humanity through human spaceflight, including the past eight-plus years alongside Dr. Kam Ghaffarian at Axiom Space,” said Suffredini. “For personal reasons, I have decided to step down as CEO, effective August 9th. I will remain as an advisor to ensure a smooth transition and continue my role as a board member.”
Dr. Ghaffarian, Axiom Space’s Executive Chairman and co-founder, will assume the role of interim CEO until a permanent successor is appointed. His extensive experience and deep industry knowledge make him well-suited to lead the company during this period.
Suffredini’s a long career at NASA before founding Axiom was crucial in establishing the company’s success. He knew how to avoid all the pitfalls of working with the government agency, and was able to negotiate the right deals to make the partnership with NASA proceed smoothly. That inside knowledge probably allowed his company to beat out Bigelow Aerospace, which had been the first to build commercial space station modules but has now faded from sight.
The result is that Axiom was to fly commercial passenger flights to ISS using Dragon capsules, and is going to likely be one of the first commercial stations to begin operations. (The race to be first is presently being led by Axiom and Vast, with Vast looking to be slightly ahead.)

Lufthansa signs deal with Airbus to train its astronauts for the Starlab space station
the proposed Starlab space station
Airbus has now signed an agreement with Lufthansa for it to train the astronauts Europe will fly to the Starlab space station, being built by a consortium of American, European, and Japanese companies.
US-based Voyager Space and Airbus signed an agreement in August 2023 to jointly pursue the development of the Starlab space station. The pair is currently targeting 2028 for the launch of the low Earth orbit destination, with commercial activities commencing in 2029. This timeline will allow for a small window of overlap with International Space Station operations before the orbiting laboratory is decommissioned in 2030.
In a 6 August announcement on Twitter, Airbus Defence and Space revealed the expanding team behind the development of Starlab. The list included Hilton Hotels for crew lodging design, Northrop Grumman for the development of an autonomous docking system for resupply spacecraft, and Lufthansa Aviation Training (LAT) for the training of future Starlab astronauts. Mitsubishi Heavy Industries, MDA Space, Palantir, and Ohio State University round out the partnership.
Though Voyager Space is supposed to be leading the project and obtained the seed money from NASA to get it started, the nature of this announcement suggests that it is Airbus who is really in charge at this time. At a minimum, the partnership has definitely transferred much control from the U.S. to Europe.
This shift should not be a surprise, since it became clear shortly after the August 2023 deal was signed that Europe had decided to focus its investment energies on Starlab and make it the European space station for the future.

Next manned Dragon mission to ISS delayed until September 24, 2024
NASA tonight announced that the next manned Dragon mission to ISS has been delayed until September 24, 2024, a pushback of more than a month caused by the thruster issues on Boeing’s Starliner capsule presently docked to the station.
This adjustment allows more time for mission managers to finalize return planning for the agency’s Boeing Crew Flight Test currently docked to the orbiting laboratory. Starliner ground teams are taking their time to analyze the results of recent docked hot-fire testing, finalize flight rationale for the spacecraft’s integrated propulsion system, and confirm system reliability ahead of Starliner’s return to Earth. NASA and Boeing continue to evaluate the spacecraft’s readiness, and no decisions have been made regarding Starliner’s return.
Since both manned capsule use the same port, Starliner must undock before a Dragon can arrive.
The schedule change also eliminates scheduling conflicts with a Soyuz capsule bringing Russian astronauts to the station in mid-September, and will also allow the launch to switch launchpads so as to not conflict with the SpaceX launch of Europa Clipper, scheduled for October 10, 2024 (though that launch remains in doubt due to other problems with the spacecraft itself).
NASA will be holding a briefing on the status of Starliner at 12:30 pm (Eastern) on Wednesday, August 7, 2024.

China launches first 18 satellites in a new Starlink-type internet constellation
China today launched the first 18 satellites in a new Starlink-type internet constellation dubbed Spacesail, its Long March 6A rocket lifting off from the Taiyuan spaceport in north China.
No word on where the rocket’s lower stage and four strap-on boosters landed within China. Jay notes that this Chinese constellation is now ahead of Blue Origin’s Kuiper constellation, a pattern that sadly has been repeated over and over again.
The leaders in the 2024 launch race:
77 SpaceX
33 China
9 Rocket Lab
8 Russia
American private enterprise still leads the rest of the world combined in successful launches 91 to 49, while SpaceX by itself still leads the entire world combined, including American companies, 77 to 63.

- K2 Space demo service bus for smallsats plans first launch in October on a SpaceX Falcon 9 transporter mission
The idea is to provide a basic service module that any satellite payload could fly on.
- Northrop Grumman’s live stream of the Cygnus docking to ISS
As we now know, it succeeded in docking on time despite the abort failures of the initial planned engine burns.

Because posting is so difficult at the resort where I am staying, and I have many other things planned for the day, I am posting Jay’s links early.
- FCC Approves AST SpaceMobile launch of first commercial satellites
Each will have the largest-ever communications array ever deployed commercially in low Earth orbit
- Europe’s autonomous orbital laboratory Space Rider undergoes helicopter drop tests
ESA hopes this spacecraft will be its own version of an X-37B
- Cygnus unmanned freighter misses its first burn, and aborts the rescheduled burn
Though NASA says it is still targeting an on scheduled docking to ISS, it is entirely unclear if this will happen.
- Rumors suggest NASA to significantly delay the launch of next crewed Dragion to ISS due to Starliner issues
The reason is that Starliner needs its flight software updated and this will take four weeks. Until Starliner undocks, there is no port for the Dragon to arrive.
I will leave it to my readers to comment on what this new stupidity tells us about Boeing. This flight software worked as planned on the second unmanned demo mission. Why should suddenly need an update while two humans are already in space and relying on it? Furthermore, Boeing had numerous flight software problems on the first unmanned demo mission, and supposedly fixed them for the second.
Posting will continue to be light until tomorrow night.

Sunspot update: In July the Sun produced the most sunspots in almost a quarter century
Every month since this website began fourteen years ago, when NOAA posts its update of its monthly graph tracking the number of sunspots on the Sun’s Earth-facing hemisphere, I post my own analysis, adding some details to provide the larger context.
Of all those updates — numbering about 168 — this month’s is possibly the most significant. Since around 2008, the Sun began a long period where it was unusually quiet, with the solar maximum that occurred in 2014 possibly the weakest in two hundred years. Before that weak maximum begun, half the solar science community predicted it would be a very powerful maximum, while half predicted a weak maximum. Both got it wrong, though the weak prediction was closer though still too high.
When it came time to predict the next solar maximum, expected around 2025, that same solar science community was once again in disagreement. Most approved a NOAA science panel prediction in April 2020 calling for another weak minimum, similar to the one in 2014. A few dissented, however, and instead predicted in June 2020 that the maximum would be one of the strongest ever. In April 2023 however those dissenters chickened out, and revised their prediction downward, still forecasting a peak higher than the NOAA prediction but no longer anywhere as intense.
Based on what happened on the Sun in July, they should have had more faith in their earlier prediction.
