Overview map

The canyon walls in one spot in Valles Marineris
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 3, 2026 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The white dot on the overview map shows the location, on the northern interior wall of Valles Marineris, the largest canyon in the solar system. The scientists took this image to get a good look at those canyon walls. I am highlighting the image because it provides a good way to illustrate the monumental scale of this vast canyon.

The inset on the overview map includes an orange dotted line, following the likely route for a trail along the nose of this ridge, going from the rim to the canyon floor. The picture to the right shows only one small section of that ridge trail, near the top. And yet, from the upper left to the lower right of the photograph a hike along that ridgeline would cover 2.2 miles and descend about 4,500 feet, a descent somewhat comparable to hiking into the Grand Canyon though dropping much more steeply. On either side of you the slopes would drop off from 1,600 to 2,000 feet.

To hike from the top of the rim to the canyon floor however would be far more challenging and be even more spectacular. The length of that orange dotted line is about 17.3 miles, with the total elevation drop about 23,000 feet — 3,000 feet greater than climbing the highest mountain in the U.S., Mount McKinley in Alaska.

Think about it. Along this part of Valles Marineris the elevation difference between the canyon floor and the rim is routinely much greater than the height of America’s tallest mountain. Every hike down into that canyon along the north wall would present a similar challenge. And from this point that northern canyon wall extends more than 650 miles westward and about 250 miles eastward. That’s a lot of Mount McKinley’s lined up in a row!

With these scales, it is at present difficult to imagine what the view from that rim would be like. You would see farther and deeper than most places on Earth, on a planet with a far thinner but more dusty atmosphere.

Astronomers detect a sugar molecule when looking towards the galactic center

9:44 am

The erythrulose sugar molecule
From Figure 1 of the paper.

Astronomers have detected for the first time a sugar molecule in interstellar space, based on data obtained when looking at a molecular cloud near the galactic center.

You can read the paper here. From the press release:

An international team led by CAB researcher Izaskun Jiménez-Serra has now identified the first sugar in interstellar space: erythrulose. This molecule is the only possible four-carbon ketose, and on Earth it is commonly found in raspberries and sunless tanning products. Erythrulose was detected toward the molecular cloud G+0.693−0.027, located near the centre of our Galaxy, the Milky Way. The discovery was made possible by ultra-sensitive, broadband spectroscopic surveys carried out with the 40-m Yebes radio telescope and the 30-m telescope of the Institute for Radio Astronomy in the Millimeter Range (IRAM).

The team identified 12 spectral lines matching the laboratory spectrum of erythrulose measured at the University of the Basque Country. The study also shows that this sugar is at least eight times more abundant than similar three-carbon sugars, none of which were detected in the same region.

Extrapolating from this data the astronomers speculate that “between 0.5 and 50 million tonnes of this sugar could have reached Earth’s surface during the Late Heavy Bombardment, which occurred approximately 4.1 to 3.8 billion years ago.” They base this conclusion on the nature of the molecule. If it could form in interstellar space, it is even more likely to have formed in the early solar system.

To put it mildly, that speculation is quite uncertain.

Astronomers think they have identified the 1st black hole inside the Milky Way’s largest globular cluster

11:08 am

Omega Centauri
Click for original image.

Using both archival data from the Hubble Space Telescope and infrared data from the Webb Space Telescope, astronomers think they have identified the first black hole ever found inside the globular cluster Omega Centauri.

The image to the right, reduced to post here, was taken by the Hubble Space Telescope and shows the globular cluster, the largest such object in the Milky Way, with an estimated 10 million stars packed into a space only 150 light years across. It is located about 17,000 light years away. Previous research had suggested it held at least one intermediate-sized black hole within it, with models suggesting another 10,000 stellar-mass black holes. Now scientists think they have found the first of the latter group, indicated by the red circle in the inset.

By sifting through more than 20 years of Hubble archival data and pulling in recent Webb data to further refine their astrometric measurements, the team located a star orbiting an invisible object so hefty that it has to be a black hole. Dubbed oMEGACat BH-2, it is the first stellar-mass black hole detected in Omega Centauri, and it has some surprising qualities. oMEGACat BH-2 has a lower-than-expected mass and, with its visible star companion, the black hole-star duo has the longest orbital period of any black hole binary system known to date.

The star orbits the black hole every 94 years. The long orbit suggests to the scientists that these objects did not form together but were captured because of the crowded nature of Omega Centauri. The scientists also believe that crowded nature will likely cause them to break free of each other, sometime in the future.

There are innumerable uncertainties and questions remaining. First, the detection needs confirmation. Second, where are the thousands of other expected stellar-mass black holes? And where is that predicted intermediate-sized one? Moreover, though astronomers believe the halo of the Milky Way’s 158 known globular clusters mark the very early history of the galaxy, much of that history remains unsettled.

BepiColumbo’s team prepares for arrival at Mercury in the fall

12:36 pm

The arrival plan for BepiColombo
Click for original graphic.

After eight years of travel through the inner solar system to get to Mercury, the European/Japanese dual orbiter mission BepiColombo is finally getting close to arrival at Mercury in the fall, and the science team has been doing rehearsals to prepare for that orbital insertion.

Teams must align timelines, verify readiness criteria and maintain a common understanding of what constitutes a ‘go’ or ‘no-go’ decision. During one recent simulation, controllers were confronted with an anomaly that forced them to abort and re-schedule a planned separation scenario. “It generates continuous discussions and iterations between the different teams,” Nacho adds.

The exercise highlighted an essential aspect of Mercury arrival: success depends not only on operating the spacecraft, but on ESA and JAXA working together as one team.

That arrival is made more complicated in that BepiColombo is not a single orbiter. It is made up of the following parts:

  • The Mercury Transfer Module (MTM), which provided the service module and ion engines for the journey, including six fly-bys of Earth, two ofVenus, and six of Mercury
  • The Mercury Planetary Orbiter (MPO) from the European Space Agency (ESA)
  • The Mercury Magnetospheric Orbiter (Mio) from Japan’s space agency JAXA
  • The Mio Sunshield and Interface Structure (MOSIF), which protected everything during its journey in the inner solar system close to the Sun

The graphic to the right outlines the arrival plan. First the MTM must separate. Then the two orbiters enter Mercury orbit. Next Japan’s Mio separates and is deployed in its own orbit. Then the sunshield is ejected from Europe’s orbiter and it moves into its planned orbit.

As the spacecraft uses ion engines, with low but continuous thrust, these maneuvers can take weeks.

Both orbiters have complementary orbits to study different aspects of the planet. Europe’s orbiter will orbit closer to get a better look at the planet, while Japan’s Mio’s orbit is highly elliptical, to study the planet’s magnetic field.

During the journey to Mercury BepiColombo overcome several problems. First, the Covid panic threatened operations by limiting staffing and preventing normal behavior. Next the solar panels failed to produce the expected power, a problem that appears to still exist but which has not prevented operations. Finally, its thrusters produced less thrust than expected during a mid-course correction in 2024, causing an eleven month delay in arrival.

It is now however about to arrive. Let us hope that arrival proceeds as planned.

More “Fluvial Processes” on Mars

More fluvial processes on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 4, 2026 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this “Fluvial processes inside crater,” an apt description based not only on the small section of the full image to the right, but on the full image itself. The entire surface of the crater floor’s western end appears filled with glacial material, in many places twisted and warped by past slow motion movements.

I picked out the area in the picture because of its particularly warped nature. It appears as if the material in the higher elevations to the upper right have been flowing downward, and in the process have pushed the glacial debris on the crater floor to the southwest.

It also appears that in the higher locations the near surface ice has been sublimating away, giving the surface a corroded look.

Bright spokes in Saturn’s rings

Bright spokes in Saturn's rings
Click for original image.

Cool image time! The picture to the right, cropped slightly to post here, was taken on December 26, 2008 from a distance of 350,000 miles by the Cassini spacecraft as it orbited Saturn. The resolution is about 37 miles per pixel.

I think sunlight is coming from the upper left, its light bouncing off the rings and thus making the those spokes bright and visible.

In the viewing geometry in which Cassini is looking approximately in the direction of the sun (called high phase), the spokes appear white against the rings because the very small particles comprising the spokes preferentially scatter light forward (in this case, toward Cassini).

At least that’s one theory for explaining the spokes that appear randomly and for only short periods within Saturn’s rings, sometimes bright, sometimes dark, depending on the angle of the Sun. According to a Hubble press release from 2023, the spokes are formed due to an interaction between Saturn’s magnetic field, the solar wind, and the tiny particles in the rings.

“The leading theory is that spokes are tied to Saturn’s powerful magnetic field, with some sort of solar interaction with the magnetic field that gives you the spokes,” said Simon. When it’s near the equinox on Saturn, the planet and its rings are less tilted away from the Sun. In this configuration, the solar wind may more strongly batter Saturn’s immense magnetic field, enhancing spoke formation.

Planetary scientists think that electrostatic forces generated from this interaction levitate dust or ice above the ring to form the spokes, though after several decades no theory perfectly predicts the spokes. [emphasis mine]

Just another strange alien phenomenon in space that remains unsolved. All we really know is that the spokes appear, remain visible for at most a rotation or two of the rings, and then disappear.

The empty desolation west of Jezero crater

The empty desolation west of Jezero crater

Overview map
Click for interactive map.

Cool image time! The panorama above was created from two pictures taken on July 1, 2026 (here and here) by the left navigation camera on the Mars rover Perseverance.

The overview map to the right provides the context. The white dotted marks the rover’s travels, with the blue dot marking Perseverance’s last posted location as of July 6, 2026. The yellow lines indicate roughly the area viewed by the panorama, taken five days earlier at a previous location.

The panorama looks west, at a low ridge line about 1,000 feet from the rover (the white dot), with a distant hill beyond (the black dot), about 4,500 feet away. The ridge is only about 50-60 feet high, while the hill rises about 600 feet. The rover’s tracks can be seen on the left.

Once again, the view from Perseverance indicates starkly the lifeless nature of Mars. Maybe it once had microbiology (though this is certainly not indicated so far by any solid evidence), but if it did, it is long long gone, and in fact likely never prospered at this location at all. NASA might claim repeatedly that Perseverance’s mission is to search for life, but every geologist on the mission knows this is a very low priority. What they are doing is studying the alien geology of another world. This image gives one a hint of its alienness.

Most specifically, Perseverance is studying a region in the dry tropics of Mars, where no near surface water remains, but also carries ample evidence of potentially valuable mineralogy. Orbital data strongly suggests the region west of Jezero crater will become a major mining region for future settlers. It might not contain any life, but it carries resources that will sustain the life that is soon to come from Earth.

The Perseverance team has been scouting this region now for the last four months, without doing any additional drilling. In fact, the last drill samples were taken at Witch Hazel Hill, in the spring of 2025. It appears they are taking their time to look for the best place to get core samples.

NASA wants its future space telescopes designed to be serviceable, like Hubble

11:04 am

In a briefing at a recent science conference, a NASA official made it clear that it wants its proposed Habitable Worlds Observatory (HWO) — presently undergoing its initial design studies for launch in the 2040s — be designed in a way that it can be maintained, repaired, and upgraded, much like the Hubble Space Telescope.

NASA is planning for HWO to be serviceable, which means that they will need to figure out a way to work on, repair, and maintain the observatory while it operates roughly a million miles (1.5 million kilometers) away. “HWO will have to be serviceable to some extent,” NASA’s astrophysics division director Shawn Domagal-Goldman told Space.com during a session at the American Astronomical Society’s (AAS) 248th meeting in Pasadena, California.

This design decision not only makes sense, NASA should have made it common practice a decade ago. The ability for robots to do this work is becoming increasingly robust, and in the next decade will become commonplace. For NASA to have launched anything in the past decade without this in mind was shameful.

NASA ends its participation in the lunar orbiter CAPSTONE

8:30 am

After four years of operation, NASA has terminated its participation in the privately built and operated lunar orbiter CAPSTONE.

The orbiter was built jointly by Terran Orbital and Rocket Lab, and launched by Rocket Lab. In space it was operated not by NASA but by the private company Advanced Space. On its way to the Moon Advanced Space’s engineers lost contact with the spacecraft twice, but were able to re-establish communications in time to save the mission, get it into orbit, where it spent four years testing a host of technologies NASA then planned to use in its Artemis program.

The orbiter is not dead however. Advanced Space “will continue to use the spacecraft as a technology development testbed.”

Webb’s mid-infrared view of the very active galaxy Centaurus A

10:57 am

Centaurus A, as seen by Webb and Hubble
Click for original Webb image. For the original Hubble image, go here.

Cool image time! The false color mid-infrared image above, reduced and annotated to post here, was taken reeently by the mid-infrared instrument on the Webb Space Telescope of the galaxy Centaurus A, 11 million light years away and known for more than a century as an elliptical galaxy crossed by a dark streak of dust, as shown by the inset, an optical Hubble Space Telescope photograph taken in July 2014. More recent research has shown the galaxy is very active, caused by the existence of a supermassive black hole in the center pulling in matter around it.

Webb’s infrared data reveals an entirely different shape. From the press release today:

Webb’s mid-infrared vision highlights the galaxy’s rich dust structures, which glow in intricate shapes that surprise and even perplex astronomers. A warped, parallelogram-like band cuts across the galaxy’s center, while wisps of material stretch outward like cosmic clouds.

An “S” shaped feature, most notable in the image from Webb’s MIRI (Mid-Infrared Instrument), is also unusual and invites questions that need further study to answer. What created this shape? How does the black hole influence it? Is it influenced by merger-induced star formation?

Many of the glowing red points in the MIRI image are dust-rich stars or stellar nurseries, where aging stars are shedding material back into space or new stars are forming. This dust is the raw ingredient for future generations of stars and planets, making it central to the ongoing life cycle of the galaxy.

Once again, this data illustrates the need for astronomers to have telescopes observing in all wavelengths and from space, since a large fraction of the electromagnetic spectrum is blocked by the atmosphere.

Europe’s Euclid optical space telescope discovers 31 new quasars in the very early universe

9:10 am

The uncertainty of science: The Europe Space Agency’s (ESA) Euclid optical space telescope — with a mirror half the size of Hubble’s — has now identified 31 new quasars in the very early universe, all of which really shouldn’t be there based on present theories as to how long it should take for them to form.

The European Space Agency’s Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed in cosmic history. They shone with the light of a trillion Suns back when the Universe was 670 million years old – just 5% of its current age.

UPDATE: Astronomers using the Keck telescopes in Hawaii have now confirmed 21 of the 31 one quasars identified by Euclid.

The scientific problem is that, according to most theories on the evolution and formation of galaxies and black holes and quasars, it takes billions of years for such large supermassive black holes to accrete their mass. Yet, these exist less than a billion years after the Big Bang. The numbers do not compute.

Euclid doesn’t get the publicity of Hubble, partly because ESA does not do as good a job of selling its work as NASA, partly because it is a European project and the American propaganda press is thus generally uninterested, and partly because it is simply smaller and a later telescope, thus not ground-breaking. Nonetheless, with a mirror 1.2 meters across, it is capable of truly spectacular optical astronomy, being above the atmosphere as well as above the many satellite constellations now in orbit. It is placed in the Lagrange point 2, a million miles from Earth.

In fact, Euclid is exactly the kind of space telescope the astronomy community should be building, in huge numbers, rather than whining about those satellite constellations blocking its big ground-based telescopes. The future of astronomy is in space, and it is high time astronomers recognized this.

Japan’s Hayabusa-2 successfully flies past asteroid Torifune

8:33 am

Torifune as seen by Hayabusa-2

Japan’s Hayabusa-2 asteroid probe successfully flew past the asteroid Torifune yesterday, getting less than 2,000 feet from its surface as it zipped past at a relative speed of more than 10,000 miles per hour.

The picture to the right is the first image released by Japan’s space agency, JAXA. It shows that Torifune appears to be a contact binary, made up of two rubble-pile asteroids that gentle fused together in their dance in space. Contact binaries are presently thought to comprise about 15% of all asteroids, but that estimate might prove to be an understatement as we gather more information. This is the first seen close-up that appears made up of two rubble piles.

While Japan’s press and its space agency touted this fly-by success loudly, both failed to mention the technical problems facing Hayabusa-2, which made the fly-by even more impressive. The spacecraft, which was launched in 2014, rendezvoused and grabbed samples from the asteroid Ryugu from 2018 to 2019, and then returned those samples to Earth in 2020, has been flying somewhat crippled. It has four ion engines for maneuvering, three of which no longer work and a fourth that is showing signs of failure. Thus, it could not do much during this fly-by to control its path or orientation. That it could grab this image as it zipped by is a testament to its engineers.

Hayabusa-2 is on its way to asteroid 1998 KY26 in 2031. Whether it will be capable of doing much when it gets there remains at this moment an unknown.

China’s Tianwen-2 successfully arrives at its target asteroid, Kamo-oalewa

China has finally confirmed that its first asteroid probe, Tianwen-2, has reached and successfully begun proximity operations next to the asteroid Kamoʻoalewa (2016HO3).

The picture to the right is the first released by China’s state-run press, apparently taken during approach to help guide it.

China’s Tianwen-2 probe has successfully arrived at a distance of 20 kilometers from the asteroid 2016HO3, enabling it to begin scientific exploration after an approximately 400-day journey of about 1 billion kilometers, the China National Space Administration (CNSA) announced on Monday.

The spacecraft will spend a year at Kamo’oalewa — which is only 130 to 440 feet across — where it will attempt to grab samples using two different methods. The first is a copy of the touch-and-go technique used by OSIRIS-REx on Bennu. The second method, dubbed “anchor and attach,” is untried, and involves using four robot arms, each with their own drill.

After delivering these samples back to Earth the plan is to send Tianwen-2 out to visit Comet 311P.

Corroding glacial debris inside Martian crater

Corroding glacial debris inside Martian crater
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 5, 2026 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this “irregular cellular structures on crater floor.” Located at 46 degrees south latitude in the Martian southern cratered highlands, we are likely looking at glacial debris that has been significantly corroded, the near surface ice sublimating away in patches because the dirt and dust that protects it has for some reason done a poor job.

In this case however the sublimation has produced these very strange features, very different than corroding subsurface ice features seen elsewhere on Mars. Reminds me of peeling paint, but even that analogy falls short.

ESA finalizes contract for privately built cubesat lander as part of its Ramses mission to Apophis

9:36 am

Apophis' path past the Earth in 2029
A cartoon (not to scale) showing Apophis’s
path in 2029.

The European Space Agency (ESA) yesterday announced it has issued the full contract with private startup EMXYS to build its Don Quijote cubesat lander for ESA’s Ramses mission to go to the potentially dangerous asteroid Apophis when it flies by the Earth in April 2029.

EMXYS, a Spanish company, previously built a gravity-measuring instrument for the cubesat Juventas, which is flying on ESA’S Hera mission presently on its way to the binary asteroid Didymos/Dimorphos.

Francesca Ingiosi, overseeing Ramses’ CubeSats, notes: “There won’t be time for sustained human oversight: Don Quijote is going to take itself down on a completely autonomous basis, relying on feature tracking to find a safe place to land. It will be running its gravimeter and magnetometer when it flies, but we have high expectations for its scientific work on the surface.

“It will come down quite slowly, but in the ultra-low gravity of Apophis some bouncing along the surface is possible. The CubeSat is therefore designed to operate from any orientation, although the precise nature of the surface remains a question mark: there is even a small possibility that Don Quijote sinks into the ground, which would not be good!

The launch window for Ramses is in the spring 2028, so the schedule to get this cubesat built is very tight.

Below is a list of the missions going to Apophis in 2029:

Katalyst’s Link rescue spacecraft launched successfully

8:41 am

Katalyst's proposed Swift rescue mission
Katalyst’s proposed Swift rescue mission.
Click for original image.

UPDATE: Katalyst engineers have established communications with Link, so the commissioning process can now begin.

———————–
Northrop Grumman’s Pegasus rocket this morning successfully launched the Link rescue spacecraft built by the startup Katalyst, aimed at rendezvousing and grabbing the Gehrels-Swift telescope and raising its orbit.

A mission to raise the altitude of NASA’s Neil Gehrels Swift Observatory is underway after launching at 8:36 p.m. Marshall Islands Time (4:36 a.m. EDT), Friday, July 3, from Kwajalein Atoll in the South Pacific Ocean.

LINK, a robotic servicing spacecraft built by Katalyst Space, launched into orbit on a Northrop Grumman Pegasus XL rocket, which was deployed by the company’s Stargazer, a modified L-1011 aircraft, at an altitude of about 40,000 feet.

The actual rescue won’t occur for several weeks, as the Katalyst team will spend several weeks checking out the spacecraft’s systems to make sure all is working as intended. Once this is assured, they will begin to slowly move towards Swift:

As it approaches, LINK will collect and send images of Swift to the ground, where teams at Katalyst and NASA will assess the planned grab points. This rendezvous and capture will be a slow and careful process that could take about a month.

Once its robotic arms are attached to Swift, LINK can begin to slowly push Swift upward. Over the course of a few months, LINK will attempt to return Swift close to its original launch altitude. Then, LINK will detach, leaving Swift in its new orbit.

The Gehrels-Swift team will then return the telescope to its operational status, following the same commissioning procedures used when the telescope was first placed in orbit in 2004.

As for the launch, this was Northrop Grumman’s second launch in 2026, and the last Pegasus launch ever. The air-launched rocket is now retired. It was created in the 1980s by the rocket startup Orbital Sciences with the intent to provide a low cost launch option. It launched a total of 46 times (with three failures in the early years), but in the past two decades it could not compete with SpaceX’s Falcon 9.

The leaders in the 2026 launch race:

79 SpaceX
42 China
10 Rocket Lab (plus two suborbital HASTE launches)
8 Russia

For the third straight year SpaceX leads the entire world combined in total launches, 79 to 74.

Sunspot update: The ramp down to solar minimum continued to stall in June

8:25 am

As I have tried to do every month since I started Behind the Black sixteen years ago, it is time for another sunspot update tracking the Sun’s sunspot activity as it evolves across its eleven year cycle. As always, I use as my basis the monthly update by NOAA of its graph showing the sunspot activity on the Earth-facing hemisphere but annotated by me with extra information to illustrate the larger scientific context.

As you can see by that graph below, June activity (the green dot) was only slightly less that in May, indicating a continuing stall in the ramp down to solar minimum, a ramp down that NOAA’s panel of solar scientists had predicted had begun in April 2025.

Long term monitoring of the dry-ice cap at the Martian south pole

Long term monitoring of the dry-ice cap at the Martian south pole
For original images go here and here.

Cool image time! The two pictures to the right, cropped and reduced to post here, were taken more than two decades apart by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The show a specific spot on the Martian south pole ice cap, at a location where there is also a perennial cap of dry ice that is also slowly shrinking in size.

The top picture was taken on May 14, 2007, the first close-up of this location. At the time the science team titled it “Fast Evolution of Landforms on the Southern Residual Caps,” which suggests that even then they had a sense from one earlier MRO picture that these strange forms were changing. As a result, scientist have used MRO to monitor this site repeatedly over the years, taking dozens of images of this location on a regular basis to track changes, both seasonally and over years.

The bottom picture is the most recent, taken on May 3, 2026. If you compare the two pictures closely, you can see that all these depressions have grown in some manner over the past two decades. (The blobs you see are all depressions. Optically your mind might make them appear as humps, but they are actually places where the cap’s top layer of dry ice has sublimated away.)

Academic publisher Springer Nature to divest itself of woke Scientific American

10:14 am

Scientific American logo
About to go the way of the dodo.

As the saying goes, “Go woke, go broke.” The academic publisher Springer Nature has now announced it is selling off its two consumer magazines, Scientific American and the German Spektrum der Wissenschaft, stating that it wishes “to focus on its core global publishing activities across research, health and education.”

I don’t know about the German magazine, but I do know that Scientific American has become a junk and very woke publication in recent years, unreliable for good reporting as its editorial policy has been instead to push a variety of leftists tropes, from queer sex theories to Covid falsehoods. As the article at the link notes,

The low-lights from the magazine’s stack of articles include:

  • Scientific American colluding with other media to normalize “climate emergency” terminology, despite vast swaths of scientific evidence showing the Earth’s climate has continuously changed over 4 billion years.
  • The magazine pushing “birth parent” terminology, which is utter nonsense in the face of real biology.
  • The magazine offering a ridiculous take on football injuries…tying them to racism.
  • Endorsing Kamala Harris for President.

Other examples of the magazine pushing junk science can be seen here and here.

The article above also notes the interesting timing of this announcement, just before the National Labor Relations Board (NLRB) was to approve the union its writer staff has recently overwhelming voted for. The unionization was supposedly about “compensation, workload, job security,” but it also included the demand for “editorial independence”, the typical code words used by the leftist journalists to demand the ability to write whatever they want, even if the magazine’s owners protest.

Well, rather than protest, this magazine’s owners decided to fire the magazine entirely.

Hat tip to reader Gary.

Launch of Katalyst’s Swift rescue mission scrubbed

8:46 am

The launch early this morning of Katalyst’s Link rescue mission to raise the orbit of the Gehrels-Swift space telescope was scrubbed due to a “launch vehicle issue” with the Northrop Grumman Pegasus rocket.

After takeoff of the L-1011 aircraft carrying the Pegasus XL, a launch vehicle issue temporarily prevented teams from deploying the rocket. The date of the next launch attempt for this mission to boost NASA’s Neil Gehrels Swift Observatory will be determined after teams have reviewed data from today’s attempt.

NASA provided no further information. This is the last Pegasus rocket existing, as the company ceased its production several years ago, with its last launch in 2021. Overall it had only been launched five times in the past sixteen years, a cadence so slow it means launch crews now are likely inexperienced or very rusty.
