SpaceX launches more Starlinks

10:05 pm

Earlier today SpaceX successfully placed another 23 Starlink satellites into orbit (including 13 with cell-to-satellite capability), its Falcon 9 lifting off from Cape Canaveral in Florida.

The first stage completed its 24th flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

62 SpaceX
30 China
6 Rocket Lab
6 Russia

SpaceX now leads the rest of the world in successful launches, 62 to 49. The company also has another Starlink launch planned for tomorrow morning.

Orbital tug startup Impulse Space wins contract with satellite company SES

3:15 pm

The orbital tug startup Impulse Space has won a contract to use its Helios tug to transport the satellites of the long established Luxembourg company SES to their correct orbit after launch.

The companies announced May 22 that they signed a multi-launch agreement that starts with a mission in 2027 where Impulse’s Helios kick stage, placed into low Earth orbit by a medium-class rocket, will send a four-ton SES satellite from LEO to GEO within eight hours. The announcement did not disclose the vehicle that will launch Helios and the satellite, or the specific SES satellite.

The agreement, the companies said, includes an “opportunity” for additional missions to transport SES satellites to GEO or medium Earth orbits.

This the first satellite tug contract for Impulse’s Helios tug, which is the larger of the company’s two tugs, the smaller version dubbed Mira. While Mira has completed an orbital demo mission, Helios has not yet flown, though it has three planned launches beginning in 2026.

Senate schedules vote for confirming Jared Isaacman as NASA administrator

2:48 pm

The Senate is now targeting early June for its vote on Jared Isaacman’s nomination as NASA administrator.

Senate Majority Leader John Thune (R-S.D.) filed cloture on Isaacman’s nomination May 22, a procedural move that would set up a vote on the nomination in early June. The Senate is not in session the week of May 26 because of the Memorial Day holiday.

Since his nomination was approved by the Senate Commerce committee in April, Isaacman has been meeting with many other senators. The article at the link does the typical mainstream press thing of pushing back 100% against the proposed NASA cuts put forth by Trump’s 2026 budget proposal, telling us that these senators were generally opposed to those cuts and questioning Isaacman about them, a claim not yet confirmed. It did note something about those senators and those proposed cuts that if true was very startling and possibly very encouraging.

While many of the proposals in the budget, like winding down SLS and Orion, were expected, the scale of the cuts, including a nearly 25% overall reduction in NASA spending, still took many by surprise. [emphasis mine]

In other words, Congress was not surprised by the proposed end of SLS and Orion. It even appears they are ready to give it their stamp of approval.

None of this is confirmed, so take my speculation with a grain of salt. Still, the winds do appear to be blowing against SLS and Orion.

Axiom signs deals with Egypt and the Czech Republic

2:39 pm

Axiom sent out two press releases yesterday touting separate agreements it has reached with two different countries that will either involve research or a future tourist flight to ISS or to its own station.

First the company announced that it has signed a partnership agreement with the Egyptian Space Agency to partner on a range of space-related research. The language describing this work was typically vague, and is so likely because it depends on the time table for the development and launch of Axiom’s station.

Second Axiom announced that the Czech Republic has signed a letter of intent to fly one of its own astronauts on a future Axiom manned flight. Like the Egyptian press release, view specifics were given, likely for the same reasons.

What both deals signal is that there is an international market for the commercial space stations under development and Axiom is aggressively working to garner that business. Its fourth commercial manned mission, set to launch in early June, carries paid government astronauts from Poland, Hungary, and India. The two new announcements add Egypt and the Czech Republic to the company’s international customers.

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.

Johannes – The Most Beautiful Wingsuit Flight I’ve Done

6:01 pm

An evening pause: From the peak of the Wetterhorn, 12,106 feet. As always, these videos don’t show the work required to get to that peak, but he does describe it on the youtube page:

We climbed over the Willsgrätli, taking around 4 hours to reach the summit of the Wetterhorn. Holy moly… this climb was serious. We didn’t use ropes, and the heavy backpack caused me some problems in certain climbing sections.

What are you planning to do this Memorial Day weekend?

Boeing and Justice Department reach new deal on criminal prosecution for 737-Max crashes

3:26 pm

In order to avoid a criminal trial scheduled for June where Boeing would be on trial for the deaths of 346 people from two 737-Max crashes in 2018 and 2019, the company and the Justice Department have worked out a new plea bargain deal that includes a much larger pay-out to the suing families of the victims.

Under the agreement, Boeing will have to “pay or invest” more than $1.1 billion, the DOJ said in its filing in federal court in Texas on Friday. That amount includes a $487.2 million criminal fine, though $243.6 million it already paid in an earlier agreement would be credited. It also includes $444.5 million for a new fund for crash victims, and $445 million more on compliance, safety and quality programs.

In the filing the Justice Department states it has met with the families to discuss the deal, but it remains unclear whether they will accept it or continue their suit. If the latter it could be that this deal will fail, just as the previous deals in 2021 and 2024. A major sticking point for the families is that Boeing will be allowed to avoid a trial and being convicted for murder and fraud, facts that the company has already admitted to in the previous deals.

Cargo Dragon undocks from ISS

2:55 pm

That this story is not news anymore is really the story. A cargo Dragon capsule that has been docked to ISS since April 22, 2025 today undocked successfully and is scheduled to splashdown off the coast of California on Sunday, May 25, 2025 in the early morning hours.

SpaceX’s Dragon missions to ISS have become so routine that NASA is not even planning to live stream the splashdown, posting updates instead online. This is not actually a surprise, since NASA has practically nothing to do with the splashdown. Once the capsule undocked from ISS, its operation and recovery is entirely in the hands of SpaceX, a private American company.

For NASA, SpaceX is acting as its UPS delivery truck, bringing back to several tons of experiments. And like all UPS delivery trucks, making a delivery is not considered news.

And yet, this is a private commercial spacecraft returning from space, after completing a profitable flight for its owners! That this is now considered so routine that it doesn’t merit much press coverage tells us that the industry of space is beginning to mature into something truly real and sustainable, irrelevant to government.

Astronomers discover a perfect sphere in radio

1:20 pm

Radio object Teleios

Using the array of radio dishes dubbed the Australian Square Kilometre Array, astronomers have made the serendipitous discovery of what appears to be a perfect sphere of radio emissions tens of light years in diameter and tens of thousands of light years away and near the galactic center.

The scientists have dubbed the object Teleios, Greek for ‘complete’ or ‘perfect’. The image to the right is that radio image. Though the astronomers posit that it must have been formed from a supernova explosion, there are problems with that conclusion. From their paper [pdf]:

Unfortunately, all examined scenarios have their challenges, and no definitive Supernova origin type can be established at this stage. Remarkably, Teleios has retained its symmetrical shape as it aged even to such a diameter, suggesting expansion into a rarefied and isotropic ambient medium. The low radio surface brightness and the lack of pronounced polarisation can be explained by a high level of ambient rotation measure (RM), with the largest RM being observed at Teleios’s centre.

In other words, this object only emits in radio waves, is not visible in optical or other wavelengths as expected, and thus doesn’t really fit with any theories describing the evolution of supernova explosions. Yet its nature fits all other possible known space objects even less, such as planetary nebulae, nova remnants, Wolf-Rayet stars, or even super-bubbles of empty space (such as the Local Bubble the solar system is presently in).

Baffled, the scientists even considered the possibility that they had discovered an artificially built Dyson Sphere, but dismissed that idea because Teleios emits no infrared near its boundaries, as such a sphere is expected to do.

At present the best theory remains a supernova remnant, though this remains a poor solution at best.

Astronomers discover another object in an orbit so extreme it reaches the outskirts of the theorized Oort Cloud

12:45 pm

Orbits of known Trans-Neptunian Objects

Astronomers analyzing a dark energy survey by a ground-based telescope have discovered what might be another dwarf planet orbiting the Sun, but doing so in an orbit so extreme that it reaches the outskirts of the theorized Oort Cloud more than 151 billion miles out.

This object, dubbed, 2017 OF201, was found in 19 different observations from 2011 to 2018, allowing the scientists to determine its orbit. The map to the right is figure 2 from their paper [pdf], with the calculated orbit of 2017 OF201 indicated in red. As you can see, this new object — presently estimated to be about 450 miles in diameter — is not the first such object found in the outer solar system with such a wide eccentric orbit. However, the object also travels in a very different region than all those other similar discoveries, suggesting strongly that there are a lot more such objects in the distant outer solar system.

Its existence also contradicts a model that proposed the existence of a larger Planet X. That theory posited that this as-yet undetected Planet X was clustering the orbits of those other distant Trans-Neptunian objects shown on the map.

As shown in Figure 2, the longitude of perihelion of 2017 OF201 lies outside the clustering region near π ≈ 60◦ observed among other extreme TNOs [Trans-Nepturnian Objects]. This distinction raises the question of whether 2017 OF201 is dynamically consistent with the Planet X hypothesis, which suggests that a distant massive planet shepherds TNOs into clustered orbital configurations. Siraj et al. (2025) computed the most probable orbit for a hypothetical Planet X by requiring that it both reproduces the observed clustering in the orbits of extreme TNOs.

…These results suggest that the existence of 2017 OF201 may be difficult to reconcile with this particular instantiation of the Planet X hypothesis. While not definitive, 2017 OF201 provides an additional constraint that complements other challenges to the Planet X scenario, such as observational selection effects and the statistical robustness of the observed clustering.

Planet X might exist, but if so it is likely simple one of many such objects in the outer solar system. It is also likely to be comparable in size to these other objects, which range from Pluto-sized and smaller, making it less unique and less distinct.

In other words, our solar system has almost certainly far more planets than nine (including Pluto).

Dawn Aerospace begins offering its suborbital spaceplane to customers

12:15 pm

Though the company has only so far flown a small prototype on low altitude supersonic test flights, the spaceplane startup Dawn Aerospace is now taking orders for those who wish to put payloads on its proposed Aurora suborbital spaceplane, targeting a first flight in late 2026.

Dawn Aerospace is taking orders now for the Aurora spaceplane for deliveries starting in 2027. The company has not disclosed pricing for the vehicle, and [CEA Stefan] Powell suggested the company would tailor pricing to each customer. He said that the company estimates, based on market research, that a per-flight price of $100,000 is “absolutely tenable,” and the price could go higher for missions with more customized flight needs. He projects Aurora could fly 100 times a year and has a design life of 1,000 flights, with a total revenue per vehicle of about $100 million.

Though the company had originally touted itself as developing an orbital spaceplane, it recently shifted its goals, at least for the present, to building a very powerful jet comparable in some ways to the X-15, capable of reaching altitudes exceeding 50 miles for short periods and short periods of weightlessness. This capability has some value, and Dawn Aerospace has decided to market it for profit, rather than wait for the orbital version that might be years away.

NASA continues to push Biden-era interpretation of Artemis Accords

11:05 am

In a press release today describing another international workshop for the signatories of the Artemis Accords in Abu Dhabi this week, NASA continued to put forth the Biden-era interpretation of the Artemis Accords that is diametrically opposed to the original concept of the accords as conceived during the first Trump administration.

The key words are highlighted in quotes below.

The Artemis Accords are a set of non-binding principles signed by nations for a peaceful and prosperous future in space for all of humanity to enjoy. In October 2020, under the first Trump administration, the accords were created, and since then, 54 countries have joined with the United States in committing to transparent and responsible behavior in space.

“Following President Trump’s visit to the Middle East, the United States built upon the successful trip through engagement with a global coalition of nations to further implement the accords – practical guidelines for ensuring transparency, peaceful cooperation, and shared prosperity in space exploration,” said acting NASA Administrator Janet Petro. “These accords represent a vital step toward uniting the world in the pursuit of exploration and scientific discovery beyond Earth. NASA is proud to lead in the overall accords effort, advancing the principles as we push the boundaries of human presence in space – for the benefit of all.”

…participants reaffirmed their commitment to upholding the principles outlined in the accords and to continue identifying best practices and guidelines for safe and sustainable exploration.

…The Artemis Accords are grounded in the Outer Space Treaty and other agreements, including the Registration Convention and the Rescue and Return Agreement, as well as best practices for responsible behavior that NASA and its partners have supported, including the public release of scientific data.

Many of the highlighted phrases are of course quite laudable, such as the desire for peace and the use of space for the benefit of all. The tone and spin however is very globalist and communist, and leaves out entirely the primary reason Trump created the accords in the first place, to encourage private ownership, capitalism, competition, and freedom in space by bypassing or canceling the Outer Space Treaty’s rules that forbid such things.

According to the release there will be more talks among accord signatories in the upcoming September meeting of the International Astronautical Congress. I highlight this press release and its Biden-era language in an effort to make the Trump administration aware that — at least in space — Biden’s policies apparently remain in charge. While I also know this is not the most important priority for Trump, it is also something he does care about, and these issues are critical for the future lives of those who will soon explore and settle the solar system.

Someone in the Trump administration has got shift NASA back to pushing for private enterprise internationally, rather than the feel-good, empty, and communist agenda of the globalist crowd, as illustrated by the language above. And they need to do it before, or even very publicly at that September International Astronautical Congress.

Pentagon official blasts ULA’s slow Vulcan launch pace to Congress

10:00 am

In written testimony to Congress submitted on May 14, 2025, the acting assistant secretary of the Air Force for Space Acquisition and Integration, Major General Stephen Purdy, blasted ULA’s very slow effort to get its new Vulcan rocket operational, causing launch delays for four different military payloads.

“The ULA Vulcan program has performed unsatisfactorily this past year,” Purdy said in written testimony during a May 14 hearing before the House Armed Services Committee’s Subcommittee on Strategic Forces. This portion of his testimony did not come up during the hearing, and it has not been reported publicly to date. “Major issues with the Vulcan have overshadowed its successful certification resulting in delays to the launch of four national security missions,” Purdy wrote. “Despite the retirement of highly successful Atlas and Delta launch vehicles, the transition to Vulcan has been slow and continues to impact the completion of Space Force mission objectives.”

The full written testimony [pdf] is worth reading, because Purdy outlines in great detail the Pentagon’s now full acceptance of the capitalism model. It appears to be trying in all cases to streamline and simplify its contracting system so as to more quickly issue contracts to startups, which were not interested previously in working with the military because they could not afford the long delays between proposal acceptance and the first payments.

In the last decade it appears this process is having some success, resulting for example in the space field the launch of multiple hypersonic tests by a variety of rocket startups. Purdy’s written testimony outlines numerous other examples.

Russia launches classified satellite

9:42 am

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

The Russians provided extensive information about the places where the rocket’s lower stages and strap-on boosters would crash, issuing “warnings for the planned rocket boosters impacts between Yar Sale and Ports Yakha settlements, as well as in Panaevsk and Khadyta-Yakha sites.” These crash zones have been used previously. Though unlike China Russia routinely warns its people about such things, like China it has never had a problem dumping these stages on their head.

The leaders in the 2025 launch race:

60 SpaceX
30 China
6 Rocket Lab
6 Russia

SpaceX still leads the rest of the world in successful launches, 60 to 49.

It is entertaining to see that the private American rocket company Rocket Lab is matching Russia launch for launch this year. Once Russia launched dozens of times per year. Now it will do well to achieve one launch per month. Rocket Lab meanwhile is trying to top twenty launches in 2025. It might not meet that number, but it is quite likely to top Russia when the year ends.

SpaceX confirms 9th test flight of Starship/Superheavy now scheduled for May 27, 2025

9:19 am

Starship/Superheavy on March 6, 2025 at T-41 seconds
Starship/Superheavy on March 6, 2025 at T-41 seconds

SpaceX has now confirmed May 27, 2025 as the launch date for the ninth test flight of Starship/Superheavy out of its Starbase spaceport at Boca Chica.

The launch window opens at 6:30 pm (Central), with the live stream beginning 30 minutes earlier. The flight will attempt to refly the Superheavy booster used on flight seven. To push the booster’s limits, it will test “off-nominal scenarios” upon return, requiring for safety that it land in the Gulf of Mexico and not be recaptured by the chopsticks. (Just as I don’t change names or my language willy-nilly because leftists demand it, I won’t play Trump’s name-changing game here. The Gulf of Mexico was given that name more than two centuries ago, most likely by the early Spanish explorers, and that name has been good enough since.)

Starship meanwhile attempt the same test profile planned for the previous two flights but stymied by the failure of the spacecraft before reaching orbit. It will test a Starlink satellite deployment system, do a relight of one of its Raptor engines, and test its thermal ability to survive re-entry.

The company also released a report describing the results of its investigation into the previous launch failure on March 6, 2025.

Perseverance moves across the barren outer rim of Jezero Crater

Looking back at the rim of Jezero Crater

Overview map
Click for interactive map.

Cool image time! While most of the mainstream press will be focusing today on the 360 degree selfie that the Perseverance science team released yesterday, I found the more natural view created above by two pictures taken by the rover’s right navigation camera today (here and here) to be more immediately informative, as well as more evocative.

After spending several months collecting data at a location dubbed Witch Hazel Hill on the outer slopes of the rim of Jezero Crater, the science team has finally had the rover move south along its planned route. The overview map to the right provides the contest. The blue dot marks Perseverance’s present location, the red dotted line its planned route, and the white dotted line its actual travels. The yellow lines mark what I think is the approximate area viewed in the panorama above.

That panorama once again illustrates the stark alienness of Mars. It also shows the startling contrast between the rocky terrain that the rover Curiosity is seeing as it climbs Mount Sharp versus this somewhat featureless terrain traveled so far by Perseverance. Though Perseverance is exploring the ejecta blanket thrown out when the impact occurred that formed Jezero Crater, that event occurred so long ago that subsequent geological processes along with the red planet’s thin atmosphere have been able to smooth this terrain into the barren landscape we now see.

And barren it truly is. There is practically no place on Earth where you could find the surface so completely devoid of life.

Some would view this as a reason not to go to Mars. I see it as the very reason to go, to make this terrain bloom with life, using our fundamental human ability to manufacture tools to adapt the environment to our needs.

Meanwhile, the science team operating Perseverance plans to do more drilling, as this ejecta blanket probably contains material thrown out from the impact that is likely quite old and thus capable of telling us a great deal about far past of Mars’ geological history.

Space Force to cut civilian workforce by 14%

9:49 am

As part of the Trump effort to reduce the size of the federal government, the Space Force will by the end of this year reduce its civilian workforce by 14%.

Civilians comprise about 5,600, or more than one-third, of the service’s 17,000 people. “Total reductions have been almost 14 percent of our civilian workforce inside the Space Force,” Saltzman said. That number is higher than the 10 percent Space Force officials previously expected to take.

And both numbers suggest that the Space Force is losing proportionally more civilians than the rest of the Defense Department, which Secretary Pete Hegseth is working to cut by five to eight percent—a process that has caused widespread uncertainty and fear among federal employees.

As is usually the case with today’s press, the article provides many quotes from people decrying these cuts. I say, it probably isn’t enough. The main job of the Space Force at this time is to issue contracts to the private sector to build satellites and spacecraft for the military. That work does not require a gigantic workforce, and it is very likely, based on the actions of this department during the Biden administration, that its leaders have been focused more on empire building that doing their job. Trimming that work force is likely practical and smart.

    The report also worried about decreasing interest in ESA’s government Iris2 constellation, proposed to compete with Starlink but far more expensive and not expected to launch for years.

    The second point is actually more important. It signals the shift among European governments away from the failed government model, something that the French parliament is apparently not yet able to comprehend.

Terraced Martian butte

12:44 pm

Terraced Martian butte
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on April 1, 2025, by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this as a “Layered Butte.” Seems like a good description. From top to bottom there appear to at a minimum about a dozen terraces, each of which represents a specific geological era on Mars.

I post this mostly because I think it shows us another example of the alien beauty of the Martian landscape. The scientific question of course is what do these layers represent. In a general sense, they indicate that over a long time period one by one these layers were laid down, and then over a likely equally long time period the top layers were worn away, one by one. The mesa is just a random spot where that erosion process was not complete, leaving behind this terraced 400-foot-high tower.

Fish & Wildlife has expanded its regulatory rule to every tree in much of the U.S.

11:35 am

Areas now subject to regulation if you intend to cut down any trees
The blue and green areas are now subject to
Fish & Wildlife regulation if you intend to cut
down any trees

Apparently in a bid to give itself more power over every proposed building project in the United States, the Fish & Wildlife Service in October 2024 (just before the election) wildly expanded its regulatory rules for protecting endangered bats.

According to the new rules, Fish & Wildlife now considers the removal of any trees at such projects to be a risk to the endangered species, because those trees “may” have been used as roosts and would therefore threaten the species ability to survive if removed.

No matter that there may be thousands of other trees nearby, including many acres of forest. If you are building anything that involves cutting down any trees, you will be subjected to Fish & Wildlife supervision that could block construction. And the area this new rule covers includes almost the entire eastern and northern parts of the United States, as shown on the maps to the right, taken from the new regulation guidelines [pdf].

Long time reader Jack O’Leary informed me of this new power grab. He also sent me information about one particular project in Massachusetts involving the installation of a well and pump station in a forested area southeast of Boston, far from any bat hibernacula. The only impact this project might have on any bats is the removal of some trees, though the project is located in a forested area with hundreds of acres of trees all around (as shown clearly on the satellite view on Google maps).

Yet Fish & Wildlife makes it clear in its letter [pdf] to the project that its “Endangered Species Act requirements are not complete.” Fish & Wildlife admits that the project will pose no direct threat to the endangered bats, but the very act of cutting down a few trees “may affect” the bats, so therefore government regulatory supervision is required.

South Africa courts Starlink; Musk says no

9:33 am

The South African government appears to be offering Starlink some concessions in order to get it approved in that country, but it also appears that Elon Musk is not interested in the deal, because it would still require the company to impose racial quotas on hiring and ownership that he not only considers immoral, but are illegal by U.S. law.

In an interview at the Qatar Economic Forum in Doha, Musk did not confirm whether a deal had been made with South Africa, as suggested in the reports. However, he maintains that Starlink’s failure to secure a license is attributed to his not being black.

“First of all, you should be questioning why there are racist laws in South Africa; that’s the problem. That’s the issue you should be attacking. The whole idea with Nelson Mandela, he was a great man, was that all races should be on equal footing in South Africa, that’s the right thing to do, not to replace one set of racist laws with another set of racist laws.”

“I was born in South Africa but can’t get a licence to operate in Starlink because I’m not black,” Musk said.

The first link notes that South Africa requires a 30% ownership by “historically disadvantaged groups, primarily Black South Africans,” a racist quota that Musk is likely to reject whole-heartedly.

China launches six satellites

9:25 am

China yesterday placed six satellites into orbit, its solid-fueled Kinetica-1 rocket lifting off from the Jiuquan spaceport in northwest China.

China claims this was a commercial launch, taking place from the launch facility at Jiuquan dedicated to commercial launches, but the rocket was built by CAS Space, a division of the Chinese Academy of Sciences. It is also solid-fueled, which means it is likely derived from missile technology, something that the Chinese government will supervise quite closely.

No word on where the rocket’s lower stages crashed inside China.

Astronomers detect evidence of exoplanet in weird orbit

9:13 am

Perpendicular planet
Click for original image.

Though there is much uncertainty in their data, astronomers now believe they have discovered an exoplanet orbiting a binary system of two brown dwarfs, but doing so tilted 90 degrees to the ecliptic of the orbits of those brown dwarfs.

The graphic to the right illustrates the theorized system, with the orbits of the brown dwarfs indicated in blue and the exoplanet’s orbit in orange. While sixteen exoplanets have been found orbiting outside a binary pair of stars, this is the first doing so at such an inclination.

The detection has great uncertainty however.

The candidate planet cannot be detected the way most exoplanets – planets around other stars – are found today: the “transit” method, a kind of mini-eclipse, a tiny dip in starlight when the planet crosses the face of its star.

Instead they used the next most prolific method, “radial velocity” measurements. Orbiting planets cause their stars to rock back and forth ever so slightly, as the planets’ gravity pulls the stars one way and another; that pull causes subtle, but measurable, shifts in the star’s light spectrum. Add one more twist to the detection in this case: the push-me-pull-you effect of the planet on the two brown dwarfs’ orbit around each other. The path of the brown dwarf pair’s 21-day mutual orbit is being subtly altered in a way that can only be explained, the study’s authors conclude, by a polar-orbiting planet.

The radial velocity method however requires the scientists to make a number of assumptions, and provides limited information that can result in a misinterpretation of the data. It is for this reason this exoplanet is described as a “candidate planet.” Its theorized existence must be confirmed by other measurements before it is considered real.

I think this was posted as a quick link back in early May, when the scientists first announced their work, but can’t find it now.

China reports discovery of new microbe on its Tiangong-3 space station

8:52 am

China’s state-run press yesterday announced the discovery of a new microbe on its Tiangong-3 space station that appears designed to survive in the harsh environment of space.

In May 2023, the Shenzhou-15 crew collected surface microbial samples using sterile wipes, preserving them at low temperatures in orbit. Subsequent ground analysis revealed the novel Niallia tiangongensis species, confirmed through multidisciplinary methods including morphological analysis, genome sequencing, phylogenetic studies and metabolic profiling, the CMSA said.

…Niallia tiangongensis demonstrates exceptional stress resistance, maintaining cellular redox balance and ensuring robust growth in extreme conditions by regulating bacillithiol (BSH) biosynthesis to counteract space-induced oxidative stress, according to the CMSA. It exhibits distinctive capabilities in biofilm formation and radiation damage repair, making it a highly adaptable “all-rounder” for space environments.

More information here. This new microbe has characteristics both different and similar to microbes found on ISS. Its discovery is also not that unique, a it appears such unusual and new biology has been found in other space-related environments, such as the clean rooms on Earth used to build spacecraft. For example, dozens were found in clean room for the Phoenix Mars lander in the early 2000s.

SpaceX launches another 23 Starlink satellites

8:28 pm

SpaceX tonight successfully placed another 23 Starlink satellites into orbit (including 13 with cell-to-satellite capabilities), its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its first flight, landing on a drone ship in the Atlantic. This was the third new booster SpaceX has launched since February. In previous years the company would about this number per year. This new crop so early this year suggests it is finding some of its older boosters might need retirement and its fleet therefore needs replenishment.

More likely the company is anticipating the planned major increases in its launch rate in both Florida and Vandenberg, and is increasing that fleet to meet the demand.

The leaders in the 2025 launch race:

60 SpaceX
29 China
6 Rocket Lab
5 Russia

SpaceX now leads the rest of the world in successful launches, 60 to 47.
