Russia launches radar satellite

3:36 pm

Russia today successfully launched a new radar Earth-observation satellite, its Soyuz-2 rocket lifting off from its Vostochny spaceport in the far east.

The leaders in the 2024 launch race:

122 SpaceX
55 China
15 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 141 to 83, while SpaceX by itself leads the entire world, including American companies, 122 to 102.

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 or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

Strange mesas in the glacier country of Mars

Overview map

Strange mesas in the glacier country of Mars

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 2, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The white dot in the overview map above marks the location, inside the chaos terrain of Deuternilus Mensae and part of the 2,000-mile-long mid-latitude Martian strip I label “glacier country,” because practically every image of every part of its landscape has glacial features. For example, the splash apron around the picture’s largest crater as well as the material within it all suggest some form of glacial activity and near-surface ice.

The scientists label what they see here as “Mesas in Small Craters.” These features are located in a low flat plain that geologists think was created when the ground eroded away, leaving behind scattered high plateaus that indicate the previous surface elevation. The geological map [pdf] of this plain describes it as follows:

Smooth, relatively featureless materials with regions of variable albedo north of continuous cratered highlands; exhibits scattered clusters of small circular to irregular knobs.

Based on the many accumulated photos from MRO, the general conclusion is that we are looking at a sheet of ice/dirt and covered by a thin dust layer that acts to protect that ice from sublimating away. When wind blows that dust off and the summer sun hits that near-surface ice, however, it does sublimate in bursts, which thus provides an explanation for the erosion that caused these low featureless plains.

As for these strange terraced mesas inside these distorted hollows, my guess is that the mesas predate the icesheet and are made of material with less ice impregnated within it. As that ice sublimates away it creates the craters within which the mesas remain. The terraces suggest a earlier series of geological sedimentary history.

Update on Astroscale’s mission to de-orbit a OneWeb satellite

9:34 am

Link here. Lots of details. The project is now targeting a ’26 launch, and if successful would be the first to capture a spacecraft in orbit and de-orbit it commercially — assuming some other orbital tug company doesn’t do it first.

One tidbit from the article that I had not known:

While the UK Space Agency and European Space Agency have provided around $35 million in funds, … Astroscale is financing “well over 50%” of the mission.

In other words, both the UK and ESA are following the capitalism model. They have left ownership and control of the de-orbit tug to Astroscale, which means they require it to obtain outside private investment capital on its own.

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.

“Toxic smell” at Progress hatch was hypergolic fuel

9:24 am

Figure 3 from September Inspector General report
Figure 3 from September Inspector General report, annotated to show Zvezda and Poisk locations.

According to information obtained by Anatoly Zak at RussianSpaceWeb.com, the “toxic smell” detected by Russian astronauts immediately after opening the hatch to unload the newly docked Progress at ISS was actually a small but very dangerous amount of hypergolic fuel left over from the previous Progress freighter.

[T]he working hypothesis was that the ground control failed to perform a routine purging of propellant lines between the station and Progress MS-27 before its undocking. As a result, highly toxic residue of hypergolic propellant remaining in the lines could easily spill into the main cavity of the docking mechanism on Poisk, once Progress MS-27 undocked from the module, an industry source told RussianSpaceWeb.com. After the arrival of Progress MS-29, the interior of the docking mechanism between the space station and the cargo ship was re-pressurized trapping the propellant residue and letting it into the station after opening of the hatches. [emphasis mine]

If true, this incident indicates a shocking level of incompetence, sloppiness, or even malice at Russian mission control. How can mission controllers forget to do a “routine purging” of hypergolic fuel, especially when it is known that this very dangerous fuel — which can dissolve skin if you allow yourself to get in contact with it — can “easily spill” into the docking port where people will travel?

The Russian government pays its top-level engineers very little, even as those engineers watch often bungling managers rake in big bucks through legal deal-making as well as bribery and embezzlement (only rarely caught and punished). These circumstances have been suggested as behind the various suspicious leaks in Soyuz and Progress capsules as well as the new Nauka module. In the case of the Soyuz, it was clearly caused by someone drilling a hole on the ground before launch and then fixing it with a makeshift patch that was certain to fail during the mission in space. Both the Progress and Nauka leaks also suggested a similar cause. The Russians told NASA its investigation discovered who drilled that Soyuz hole, but never revealed what it had found. As for the Progress and Nauka leaks, no investigation results were ever even discussed.

There is something distinctly rotten within Roscosmos, a rottenness that it appears Russia is doing little to fix. More likely it can’t really fix it, because the Putin administration in the late 2000s made Russia’s aerospace industry a remake of the Soviet Union, a single government-run corporation that owns everything and blocks all competition. Since then it has shown a steady decline in its ability to accomplish much and the steady growth of problems such as this.

The sooner Americans no longer have to partner with Russia the better. We must hope that NASA can at least get to 2030 and its planned retirement of ISS without a major failure. This leak occurred within the Poisk docking module that is attached to the larger Zvezda module where air is leaking from the station due to serious stress fractures in its hull. Each docking puts more stress on Zvezda, risking a catastrophic failure, so much so that it is now NASA policy to close the hatch between the American and Russian halves of the station whenever such dockings take place.

Aaron Copland – “The Promise of Living” from The Tender Land

6:01 pm

An evening pause: I posted this for Thanksgiving in 2012 and 2015. Time to post again. As I wrote in 2015:

The hope of America will always live on, even when America is gone. Ordinary people want freedom, love, family, and the right to live their lives as they wish, without harming others, so they can bring in “the blessings of harvest,” whatever that harvest might be. It must be our goal to allow that to happen, and to stop those that wish to prevent it.

UPDATE: Launch did not occur

3:15 pm

UPDATE: Thanks to my readers (see below), we can now confirm that the launch listed below did not occur as indicated at the link I provided, and is rescheduled for a few days hence. I have therefore removed this launch from Russia’s totals for 2024.

The corrected leaders in the 2024 launch race:

122 SpaceX
55 China
14 Russia
13 Rocket Lab

American private enterprise leads the rest of the world combined in successful launches 141 to 82, while SpaceX by itself leads the entire world, including American companies, 122 to 101.

The original post, minus the launch totals:
————————
Russia yesterday apparently launched a classified military payload, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in northwest Russia.

This launch however remains unconfirmed by any other sources. No information about its launch or payload appears available on line, except for the link I provide above. Though I am adding it to Russia’s launch totals, I will remove if if further information proves it did not happen.

Lincoln proclaims a day of Thanksgiving — in the middle of the Civil War

9:01 am

Abraham Lincoln
Abraham Lincoln

As I wrote in 2023 for Thanksgiving last year, just six weeks after the horrible murderous massacre of innocent people by Hamas on October 7, 2023:

The date was October 3, 1863. The Civil War was at its height, with no end in sight and no clear sign yet of victory for the Union. For all anyone knew, the great American experiment in self-government, freedom, and constitutional law was about to end in failure, with one half of the nation committed to the idea that it was okay to enslave other human beings, based on their race.

In such a moment, President Abraham Lincoln did what all past leaders in America had done, call for a day of prayer to God for the future while giving thanks for the blessings still abounding. For this purpose he set aside the last Thursday of November of that year.

Since then, Americans have never stopped celebrating Thanksgiving on that day. Today comes another Thanksgiving during a time of chaos, hate, violence, and oppression. There is much to invoke horror and outrage.

There is much more to be thankful for. As much as some have tried to squelch freedom here in America and abroad, all signs say that freedom-lovers everywhere are refusing to go down without a fight. Let us join together to renew that effort, so that “government of the people, by the people, for the people, shall not perish from the earth.”

Thanksgiving continues to be an utterly American holiday. No other nation has anything like it. And it lives on, because deep down, all ordinary Americans — from all walks of life and political persuasions — are still hopeful and determined to build a life for themselves and their loved ones, with joy and justice and freedom at its heart.

Thus, the words of Lincoln’s 1863 Thanksgiving proclamation still rings true to us all. Let us put aside our petty factional differences and, as Lincoln asked, give thanks as “one heart and one voice by the whole American People.”
—————————–
A Proclamation.

The year that is drawing towards its close, has been filled with the blessings of fruitful fields and healthful skies. To these bounties, which are so constantly enjoyed that we are prone to forget the source from which they come, others have been added, which are of so extraordinary a nature, that they cannot fail to penetrate and soften even the heart which is habitually insensible to the ever watchful providence of Almighty God.

    Though the mission was able to do the first seismology on Mars, overall it was a troubled mission. It was delayed years because the first seismometer, built by France, didn’t work and had to be replaced, and then the second science instrument, a German-built drill designed to drill down five meters, failed to work on Mars.

Unusual light-colored Martian dunes

Unusual light-colored Martian dunes
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 27, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The picture was simply labeled a “terrain sample,” which usually means it was taken not as part of any specific research request, but to fill a gap in the schedule so as to maintain the camera’s proper temperature. When such gap-filler pictures are necessary, the MRO camera team tries to snap something of interest. Sometimes the pictures end up somewhat boring. This time however the picture highlights a dune field that is unusually light in color.

Since most Martian sand is volcanic in origin, it tends to look dark in orbital pictures. That this sand looks bright could be because it is inherently different, or it could be that lighting conditions make what normally looks dark to look bright instead.

Trump’s picks to run all the federal health agencies guarantees major change is coming

1:02 pm

Trump defiant after being shot
Trump defiant

Fight! Fight! Fight! The announcement late yesterday that president-elect Donald Trump has picked Jay Bhattacharya, the director of Stanford University’s Center for Demography and Economics of Health and Aging, to head the National Institutes of Health (NIH) underlined quite forcefully the certainty that the outsider nature of all of Trump’s picks to head all the health-related agencies in the federal government will led to major changes in how those agencies operate.

Bhattacharya had been blacklisted for his very vocal opposition to the government’s lockdown and mandate policies during the COVID epidemic. He along with Martin Kulldorff, one of the world’s foremost experts on vaccines and who was also blacklisted during the epidemic, co-authored the Great Barrington Declaration that strongly criticized the policies imposed by these health agencies, calling instead for a return to the standard response to infectious diseases that had been followed successfully for more than a century.

Putting Bhattacharya in charge of NIH is incredibly ironic. When he along with Kulldorff had come out opposed to the lockdown and jab mandates advocated by Francis Collins, then-head of the NIH, Collins in league with Anthony Fauci, then head of National Institute of Allergy and Infectious Diseases (NIAID), put together a back-room campaign to have Bhattacharya, Kulldorff, and many others blacklisted across social media. This campaign also had Kulldorff removed as a member of the CDC’s vaccine safety advisory committee.

Two years later, Collins is now gone, is being sued for his actions, and Bhattacharya has replaced him.

Trump’s defiant choice of Bhattacharya however is only one of many similar decisions, beginning last month with the choice of Robert Kennedy Jr. to run the Department of Health and Human Services.

NASA: forcing it to fly VIPER would cause it to cancel funding to 1 to 4 other commercial lunar landers

10:31 am

VIPER's planned route on the Moon
VIPER’s now canceled planned route at the Moon’s south pole

According to a response by NASA to a House committee and obtained by Space News, if Congress forces the agency to fly its canceled VIPER moon rover NASA would have to cancel funding to one to four other commercial lunar landers being built by private companies as part of NASA’s CLPS program.

In one scenario, NASA assumed VIPER would launch on Astrobotic’s Griffin lander as previously planned in September 2025. The agency estimated it would need to spend $104 million to prepare VIPER itself, $20 million of which had already been allocated for activities in fiscal year 2024, along with $20 million in “additional risk mitigation activities” for Griffin. “NASA estimated that these additional funding requirements would lead to cancellation of one CLPS delivery and delay of another delivery by a year,” it stated.

A second scenario anticipated a one-year slip in VIPER’s launch to September 2026. NASA projected an additional $50 million in costs for VIPER and $40 million for Griffin. That would have resulted in two canceled CLPS task orders and a one-year delay to two others.

NASA also revealed it considered “alternative delivery means” for VIPER other than Griffin. NASA did not disclose details about those alternatives, calling them “highly proprietary” but which would have delayed the launch of VIPER beyond 2026 “and would still include significant uncertainty about the reliability of delivery success.” NASA projected total costs of $350 million to $550 million with this scenario, resulting in the cancellation of four CLPS task orders and delaying three to four more by two years.

NASA preferred option is for a private company to take over VIPER. At the moment the agency is reviewing eleven proposals put forth by such companies that has “enough spaceflight experience and technical abilities to conduct the VIPER mission.”

Congress has gotten involved because the science community has lobbied hard to save it. The project itself has been a problem for NASA since its first iteration as Resource Prospector, when NASA would have built both the rover and lander. It has consistently gone over budget and behind schedule, even after NASA gave the lander portion to a private company, Astrobotic. At present the rover is 3X over budget with more overages expected, which is why NASA cancelled it.

American spaceplane startup signs deal with Australian spaceport startup

10:17 am

Australian commercial spaceports
Australia’s commercial spaceports. Click for original map.

The American spaceplane startup Titans Space, which hopes to develop a reusuable space plane based on designs developed in the 1970s by Rockwell, has now signed a deal with the Australian spaceport startup Space Port Australia to work together to find an Australian location for both building the spaceplane and launching it.

Titans Space, a company that is taking an innovative approach to the space industry, has ambitious plans to become the largest low-earth orbit and lunar space tourism company in the world, as well as the largest “real estate owner in space and the Moon”.

Space Port Australia, which is headquartered in the NSW regional town of Moree, is committed to creating an integrated space facility which fosters innovation, industry, education and helps grow Australia’s place in the space sector.

Though Titans has raised some investment capital, this project is right now in its aspirational phase. It is very possible none of this will happen. This announcement is mostly an attempt to generate interest in both projects.

As for Space Port Australia, if it finds a location for this project it would be the fourth spaceport in Australia, joining the three spaceports that already have completed or have planned launches, as shown on the map to the right.

FCC approves use of Starlink for direct cell-to-satellite T-Mobile service

10:02 am

Despite objections from all of SpaceX’s competitors, the FCC has now approved the use of its Starlink constellation for direct cell-to-satellite service as part of T-Mobile’s cellular network.

The decision noted that many technical issues still must be cleared.

There are a few limitations on how this type of service (which the FCC calls “supplemental coverage from space,” or SCS) can work. Right now it officially has to operate as an extension of an existing terrestrial provider, in this case T-Mobile. That’s because the regulations on how you broadcast stuff in space are different from those for how you broadcast stuff to and from a phone (as opposed to a base station antenna). AT&T, for its part, is partnering with AST SpaceMobile.

SpaceX must also be sure that its service does not interfere with other services on the ground, while the ground services do not have to worry about whether they might interfere with the satellite signals.

Nonetheless, this approval likely means that soon users of T-Mobile (as well as AT&T) will no longer have any dead zones. When there are no cell towers available, their phones will simply access the orbiting constellations of either Starlink or AST SpaceMobile.

ESA flies suborbital rocket from Swedish spaceport

9:55 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

The European Space Agency (ESA) yesterday successfully flew a small suborbital rocket from the Esrange spaceport in Sweden, completing the sixteenth such flight since 1987.

The rocket reached an altitude of 256 km before falling back to Earth and providing approximately six minutes of microgravity to six scientific experiments onboard.

…All systems performed well during the flight and the valuable payloads were recovered by helicopter soon after landing. Flight samples of the experiments will now be returned for further analysis to science teams from Sweden, Germany and Finland, after more than two years of preparations.

This suborbital launch is only a preliminary of much bigger things to come. The rocket startup Firefly is building a launchpad at Esrange for orbital launches. Furthermore, the European startup MaiaSpace, a subsidary of ArianeGroup, plans to do tests of its partly reusable Maia rocket there in 2025.

Judge dismisses lawsuit against SpaceX by activists

9:41 am

A federal judge has now thrown out a lawsuit that had been filed by anti-Musk activists in an attempt to halt all launches by SpaceX of its Starship/Superheavy rocket at Boca Chica.

U.S. District Judge Rolando Olvera issued his ruling last Thursday in response to the request filed by Save RGV on Oct. 9. The group has alleged that SpaceX’s water deluge system is releasing untreated industrial wastewater during launches and sought to halt the launches.

The water deluge system is designed to dampen the effects of Starship’s rocket engine blasts during liftoff and static fire engine testing.

“At the beginning of the Starship-Super Heavy Launch System’s development, it became evident that a deluge water system was necessary to protect the launch site and surrounding areas during launches,” Olvera wrote in the order. “A deluge water system sprays large quantities of potable water at the base of the spacecrafts during launch to prevent fires and reduce dispersal of dust and debris.

“Because of these dangers, Defendant cannot launch its spacecrafts without the deluge water system.”

SpaceX had argued that environmental reviews by both federal and state agencies had determined that the deluge system caused no harm. Olvera concurred, and also noted that to block launches would do significant harm to SpaceX and NASA’s entire lunar program.

This activist group, which represents almost no one in southern Texas, has no real interest in the environment. It filed this and other lawsuits simply as lawfare to try to stymie SpaceX for political reasons, knowing that we have more than seven decades of data at spaceports in Florida and California that prove rocket launches and deluge systems cause no environmental harm. In fact, they help wildlife by creating a large refuge where that wildlife can thrive.

Expect further similar lawsuits, all of which will be summarily dismissed afterward.

What I wonder is who is paying for this lawfare? SaveRGV likely doesn’t have the resources.

Engineers restore Voyager-1 after communications issue

9:20 am

The Voyager missions
The routes the Voyager spacecraft have
taken since launch.

Engineers have now manged to resume normal communications with the Voyager-1 interplanetary probe after it had shut down its main communications channel last month due to low power levels.

Earlier this month, the team reactivated the X-band transmitter and then resumed collecting data the week of Nov. 18 from the four operating science instruments. Now engineers are completing a few remaining tasks to return Voyager 1 to the state it was in before the issue arose, such as resetting the system that synchronizes its three onboard computers.

The X-band transmitter had been shut off by the spacecraft’s fault protection system when engineers activated a heater on the spacecraft. Historically, if the fault protection system sensed that the probe had too little power available, it would automatically turn off systems not essential for keeping the spacecraft flying in order to keep power flowing to the critical systems. But the probes have already turned off all nonessential systems except for the science instruments. So the fault protection system turned off the X-band transmitter and turned on the S-band transmitter, which uses less power.

The S-band transmitter had not been used since 1981, so it took awhile for ground engineers to find the very weak signal. Once found however it was possible to recover operations, though those operations will likely continue for only another year or two. The spacecraft’s power supply is expected to finally run out sometime in ’26 or ’27.

Two launches early today

9:11 am

China and SpaceX successfully completed launches early today.

First, the Chinese pseudo-company Landspace launched a new version of its Zhuque-2 methane-fueled rocket, lifting off from the Jiuquan spaceport in the northwest of China. The mission placed two test satellites into orbit, but more important, the launch tested the rocket’s new fuel-loading systems that copies SpaceX’s, loading the fuel quickly and cooling it to a lower temperature to increase its density and thus allow more to be packed into its tanks.

No word on where the rocket’s first stage crashed inside China.

SpaceX then placed 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida. The first stage completed its fifteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

122 SpaceX
55 China
14 Russia
13 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 141 to 82, while SpaceX by itself leads the entire world, including American companies, 122 to 101.

Etched terrain on Mars

Etched terrain on Mars
Click for original image.

Today’s cool image is another example of what I call a “What the heck!” image. The picture to the right, simply cropped to post here, was taken on September 22, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

It shows what the scientists label as “etched terrain,” an incredibly twisted and eroded landscape that to me actually defies description. In trying to research what scientists have learned and theorized about this terrain, it appears they think it is material that flowed over older terrain (thus its lack of many craters) that was subsequently eroded by later processes.

Why it eroded so strangely however is not really understood. It could have been caused by near-surface ice sublimated to the surface and thus causing many breaks, but since this terrain is located right on the equator in the dry tropics, it is a very long time since water was present here.

Hubble vs Webb, or why the universe’s secrets can only be uncovered by looking at things in many wavelengths

11:15 am

Hubble view of Sombrero galaxy
Click for original image.

Time for two cool images of the same galaxy! The picture above shows the Sombrero Galaxy as taken by the Hubble Space Telescope in 2003. The picture below is that same galaxy as seen by the Webb Space Telescope in the mid-infrared using false colors. From the press release:

In Webb’s mid-infrared view of the Sombrero galaxy, also known as Messier 104 (M104), the signature, glowing core seen in visible-light images does not shine, and instead a smooth inner disk is revealed. The sharp resolution of Webb’s MIRI (Mid-Infrared Instrument) also brings into focus details of the galaxy’s outer ring, providing insights into how the dust, an essential building block for astronomical objects in the universe, is distributed. The galaxy’s outer ring, which appeared smooth like a blanket in imaging from NASA’s retired Spitzer Space Telescope, shows intricate clumps in the infrared for the first time.

Researchers say the clumpy nature of the dust, where MIRI detects carbon-containing molecules called polycyclic aromatic hydrocarbons, can indicate the presence of young star-forming regions. However, unlike some galaxies studied with Webb … the Sombrero galaxy is not a particular hotbed of star formation. The rings of the Sombrero galaxy produce less than one solar mass of stars per year, in comparison to the Milky Way’s roughly two solar masses a year. Even the supermassive black hole, also known as an active galactic nucleus, at the center of the Sombrero galaxy is rather docile, even at a hefty 9-billion-solar masses. It’s classified as a low luminosity active galactic nucleus, slowly snacking on infalling material from the galaxy, while sending off a bright, relatively small, jet.

In infrared the galaxy’s middle bulge of stars practically vanishes, exposing the weak star-forming regions along galaxy’s disk.

Both images illustrate the challenge the universe presents us in understanding it. Basic facts are often and in fact almost always not evident to the naked eye. We always need to look deeper, in ways that at first do not seem obvious. This is why it is always dangerous to theorize with certainty any explanation too soon, as later data will always change that explanation. You can come up with an hypothesis, but you should always add the caveat that you really don’t know.

By the way, this concept applies not just to science. Having absolute certainty in anything will almost always cause you to look like a fool later. Better to always question yourself, because that will make it easier for you to find a better answer, sooner.

We need only look at the idiotic “mainstream press” during the months leading up to the November election to have an example of someone with certainty who is now exposed as an obvious fool.

Firefly’s Blue Ghost lunar lander now targeting mid-January launch window

10:08 am

Landing sites on Moon

According to a media update from NASA yesterday, Firefly’s Blue Ghost lunar lander now targeting mid-January launch window for its unmanned mission to the Moon.

A six-day launch window opens no earlier than mid-January 2025 for the first Firefly Aerospace launch to the lunar surface.

The Blue Ghost flight, carrying 10 NASA science and technology instruments, will launch on a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. Media prelaunch and launch activities will take place at NASA Kennedy.

The first quarter of 2025 will be a busy time for unmanned missions to the Moon. In addition to Firefly’s mission, the American startup Intuitive Machines also hopes to launch its Athena lander to the Moon’s south pole in February. Though it will launch after Blue Ghost, it will get to the Moon first, as it is taking a more direct week-long route compared to Blue Ghost’s 45-day journey. In addition, the Japanese company Ispace is targeting its own January launch for its Resilience lander.

If all three lift off as planned, there will be three landers heading for the Moon in early 2025.

Engine for Japan’s new Epsilon-S rocket explodes during static fire test

9:36 am

For the second time in a row an engine for Japan’s new Epsilon-S rocket has exploded during a static fire test.

The test was conducted inside of the restricted area at Japan’s Tanegashima Space Center in southwestern Japan, and the Japan Aerospace Exploration Agency is investigating, Chief Cabinet Secretary Yoshimasa Hayashi told reporters.

An Epsilon project manager, Takayuki Imoto, told an online press conference from Tanegashina that the explosion occurred 49 seconds into the planned two-minute test, causing fire and scattering broken parts of the engine and damaging the facility.

The Epsilon-S is being built by Japan’s space agency JAXA. It is intended to replace the solid-fueled Epsilon rocket that was initially conceived in 2013 to lower launch costs and provide JAXA with a rocket that could complete with the many new smallsat rocket startups worldwide. That rocket however only launched six times and never achieved its goals. JAXA had been targeting March for the first launch of Epsilon-S, but that is now unlikely, especially considering these two engine failures during tests.

France to resume suborbital launches at French Guiana

9:14 am

Now that France’s space agency CNES has taken the management of its French Guiana spaceport back from the European Space Agency’s Arianespace government company, it has been moving to make the spaceport more attractive to multiple future launch customers. Previously it announced that it is offering launchpads to multiple new rocket startups. Now it has announced that has signed a contract with the French startup Optus Aerospace to reopen its closed suborbital launchpad for the first time in decades.

Officially inaugurated in 1968, the Ensemble de Lancement Fusées-Sondes (ELFS) launch complex hosted the Guiana Space Centre’s first launch on 9 April 1968, with a Véronique sounding rocket that reached an altitude of 113 kilometres. Between 1968 and 1992, more than 350 sounding rockets were launched from the facility.

On 25 November, CNES announced that it had signed a contract with Opus Aerospace to use the ELFS facility for the launch of its Mésange rocket.

In other words, under the control of a government entity, Arianespace, which also controlled all European launches for decades, the variety of launches declined. As soon as control was lifted from this government monopoly however the possibilities expanded quickly.

SpaceX wins launch contract for Dragonfly mission to Titan

8:58 am

NASA yesterday announced that it has awarded the launch contract for sending its Dragonfly mission to Titan to SpaceX’s Falcon Heavy rocket.

The firm-fixed-price contract has a value of approximately $256.6 million, which includes launch services and other mission related costs. The Dragonfly mission currently has a targeted launch period from July 5, 2028, to July 25, 2028, on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Dragonfly is a truly cutting edge mission. Though we have relatively limited information about Titan’s atmosphere and the environment on its surface, it will attempt to fly there like a helicopter, landing and taking off multiple times.

And though there are certainly additional costs required for such a mission, that quarter-billion dollar contract price probably triples what it normally costs SpaceX for a Falcon Heavy mission. Even if it requires the expending of all three first stages, the company is almost certainly getting a big windfall from this deal.

  • Landspace touts upgrades it is planning for its Zhuque-3 rocket
    It hopes to do the first three launches in 2025 using the older version, and then upgrade. A comparison of its Zhuque-2 and Zhuque-3 rockets can be viewed here. Zhuque-2 has launched three times successfully, though nothing in the past year. Zhuque-3 will attempt to reuse its first stage.
