- NASA touts its help to Vast in building the company’s Haven-1 space module
NASA provided the facilities and advice that allowed the company to test the module’s atmospheric filtering systems.
- China touts the 2-meter diameter of its Xuntian space telescope, designed to closely match Hubble and fly in formation with its Tiangong-3 space station for repair and maintenance
The link says the launch is now targeting 2026, but a report last year it was probably delayed to 2027. Originally China wanted to launch the telescope in 2024.
- Northrop Grumman touts is new medium launch vehicle, Eclipse, built in partnership with Firefly
I could be wrong, but at first glance this appears to be the Antares rocket using Firefly’s first stage (replacing its Ukrainian-built first stage), and renamed.

Elon Musk’s presentation “The Road to Making Life Multiplanetary”
The Musk game plan for Mars exploration over the next few years.
It appears Elon Musk finally gave his public presentation to SpaceX employees today, entitled “The Road to Making Life Multiplanetary”, and had it posted on X.
I have embedded that presentation below.
After reviewing the present development program for Starship/Superheavy (without mentioning anything about this week’s flight), Musk then outlined the game plan for the the next few years, as shown in the graphic above. If all goes as planned (not to be expected), the first Starships will head to Mars in about eighteen months, at the next launch window near the end of 2026. These flights will be unmanned, and will require that by then SpaceX will have also developed orbital refueling capability.
Musk hopes the first manned missions will take place at the next launch window in 2028-29, with the number of ships increased from 5 to 20. Later windows will see 300 and then 500 ships launched. For those flights a lot of work will need to be done to make Starships function as interplanetary spaceships, something it appears SpaceX and Musk have not yet devoted much energy to.
As always, Musk’s target goals are ambitious and not likely to be met. But as always, his targets are not unreasonable, which means SpaceX will likely eventually get all this done but late by only one or several launch windows.
Musk also noted that this entire program is presently being funded by Starlink revenues. The government for SpaceX and Musk’s space exploration plans is largely now irrelevant. This fact is possibly the most historically significant revelation in his presentation.
I strongly recommend you watch his whole speech, if only to enjoy the “Wow!” factor.
The future is going to be exciting for sure.

Just as I refuse to say “native American”, I refuse to say “Gulf of America”
A British map from 1700, with the Gulf of Mexico
labeled at “The Great Bay of Mexico”
The recent effort by Donald Trump to get the name of the Gulf of Mexico changed to the “Gulf of America” appears at first glance to have many laudable aspects, the most important of which his desire to energize the American people to have pride in their country. For too long young Americans have been indoctrinated with the anti-American Marxist poison pushed by our modern bankrupt academic community, and have thus been trained to think timidly and with hate about their own country.
Advocating this name change is Trump’s way of quickly countering that negativity. The United States is founded on noble principles — “life, liberty, and the pursuit of happiness” — and it has lived up to those ideals with remarkable success during its entire 250 year history. Thus, Americans have plenty to be proud of, and to Trump’s mind something needed to be done to underline that fact.
Hence, his push to change the “Gulf of Mexico” to the “Gulf of America.”
And yet, as much as I support his general effort to invigorate Americans to their glorious past, to my mind this particular effort by Trump is as false and as shallow as the left’s never-ending demands that we use new language for everything. American Indians should be “native Americans”, even though everyone born in the U.S. is native. “Chairman” must become “Chair” or “Chairperson,” even though such usage is ugly and unnecessary. Spaceflight can never be “manned,” football teams can’t be “Redskins,” and “communists” must now be called “progressives.”
And worst of all we must all use the pronouns demanded by perverts, even if when by doing so we are denying reality.
Such abuse of language offends me, as a writer. » Read more
Chinese pseudo-company completes successful hop test of rocket
YXZ-1 completing soft splashdown vertically.
Click for movie.
The Chinese pseudo-company Space Epoch (also called SEpoch) announced today a successfully hop test yesterday where its prototype YXZ-1 grasshopper-type test prototype completed a vertical launch to an altitude of about 1.5 miles, shut down its engines, then relit them to achieve a soft splashdown over water.
The test article used thin-walled stainless steel and had a diameter of 4.2 meters, a total height of 26.8 meters and a takeoff mass of about 57 tons, according to Space Epoch. The test lasted 125 seconds and reached around 2.5 kilometers in altitude. The test article used Longyun methane-liquid oxygen engines provided by [pseudo]-commercial firm Jiuzhou Yunjian (JZYJ).
Sepoch says the test has laid a solid foundation for the first full flight of the YXZ-1, also known as Hiker-1 in English, later this year.
Without question China’s pseudo-companies as well as its official state space divisions are aggressively pursuing reusable rockets, far more aggressively than any companies (other than SpaceX) in the west. There are at least nine Chinese pseudo-companies or government agencies testing rockets that can land vertically (Space Epoch, Landspace, Deep Blue, Shanghai Academy of Spaceflight Technology, Chinese Academy of Sciences, Space Pioneer, Ispace, Galactic Energy, Linkspace), with eight having attempted hop tests with mixed results.
In the west, only SpaceX is flying reusable rockets. Blue Origin’s New Glenn is supposed to be reusable, but it has only launched once and on that flight its first stage failed to land successfully. The company has only done hop flights with its small suborbital New Shepard spacecraft. Rocket Lab is building its reusable Neutron rocket, but it also has never done any hop tests with that rocket. Stoke Space plans a completely reusable rocket, with the second stage returning as well, and has done one short hop test of a prototype of that stage. Other rocket companies are designing or developing such rockets, but none have done any hop tests.
In general China’s rocket industry appears far ahead in this race.

Scientists believe they have detected the actual process in which Mars loses its atmosphere
The uncertainty of science: Scientists using three different instruments on the Mars orbiter MAVEN now believe they have detected evidence of the actual process in which Mars loses its atmosphere, dubbed “sputtering”.
To observe sputtering, the team needed simultaneous measurements in the right place at the right time from three instruments aboard the MAVEN spacecraft: the Solar Wind Ion Analyzer, the Magnetometer, and the Neutral Gas and Ion Mass Spectrometer. Additionally, the team needed measurements across the dayside and the nightside of the planet at low altitudes, which takes years to observe.
The combination of data from these instruments allowed scientists to make a new kind of map of sputtered argon in relation to the solar wind. This map revealed the presence of argon at high altitudes in the exact locations that the energetic particles crashed into the atmosphere and splashed out argon, showing sputtering in real time. The researchers also found that this process is happening at a rate four times higher than previously predicted and that this rate increases during solar storms.
This sputtering is believed to be the process in which Mars lost the thick atmosphere that scientists believe must have existed in the past so that liquid water could exist on the planet’s surface. When MAVEN arrived in Mars orbit ten years ago the scientists actually thought the spacecraft would detect it relatively quickly. That it took ten years to finally find some evidence it is occurring suggests something is not quite right with their theories.

China launches classified satellite
China today successfully launched a classified Earth observation satellite to do “national land surveys, environmental management and other fields,” its Long March 4B rocket lifting off from its Jiuquan spaceport in northwest China.
No word on where the rocket’s lower stages, which use very toxic hypergolic fuels, crashed inside China.
The leaders in the 2025 launch race:
65 SpaceX
32 China
6 Rocket Lab
6 Russia
SpaceX still leads the rest of the world in successful launches, 65 to 51.

South Korea rocket startup launches small prototype rocket
Unastella rocket at launch
A South Korea rocket startup dubbed Unastella on May 28, 2025 successfully launched a small prototype suborbital rocket from its own launch site near the country’s southern coast.
UNA EXPRESS-I is 9.45 meters long and has a total weight of 2 tons. It is a small launch vehicle that uses kerosene (jet fuel) and liquid oxygen as fuel, with a thrust of 5 tons. The vehicle successfully completed its flight to the target distance of 10 kilometers and fell into the maritime safety zone set by Goheung County, the company stated. Park Jae-hong, the CEO of Unastella, noted, “For the first launch, we lowered the altitude for safety and extended the reach.”
This is South Korea’s second rocket startup that has launched a small test prototype, the first being Innospace which launched its test rocket from Brazil in 2023 and hopes to do an orbital launch before the end of the year.
It appears that South Korea is shifting successfully to the capitalism model. Back in 2023 it was trying to develop its government-built Nuri rocket, but that development seems to have stalled. Since then its newly formed space agency has established policies encouraging private space commercialization, which has apparently resulted in these two new rocket companies.

New data suggests Europa’s surface is constantly changing
Click for original graphic.
The uncertainty of science: Using data collected by the Webb Space Telescope combined with modeling and lab experiments, scientists now think they have found evidence that Europa’s surface is constantly changing, with materials from its interior being brought to the surface.
This new study found crystalline ice on the surface as well as at depth in some areas on Europa, especially an area known as Tara Regio. “We think that the surface is fairly porous and warm enough in some areas to allow the ice to recrystallize rapidly,” said Dr. Richard Cartwright, lead author of the paper and a spectroscopist at Johns Hopkins University’s Applied Physics Laboratory. “Also, in this same region, generally referred to as a chaos region, we see a lot of other unusual things, including the best evidence for sodium chloride, like table salt, probably originating from its interior ocean. We also see some of the strongest evidence for CO2 and hydrogen peroxide on Europa.”
…“Our data showed strong indications that what we are seeing must be sourced from the interior, perhaps from a subsurface ocean nearly 20 miles (30 kilometers) beneath Europa’s thick icy shell,” said [Dr. Ujjwal Raut of the Southwest Research Institute and co-author of the paper]. “This region of fractured surface materials could point to geologic processes pushing subsurface materials up from below. When we see evidence of CO2 at the surface, we think it must have come from an ocean below the surface.”
The graphic to the right shows the detected variations across the surface of Europa, based on the Webb spectroscopic data. It also illustrates nicely the coarseness of this data, its lack of resolution, and the uncertainties involved. The scientists have found evidence that suggests the surface is changing, but the key word here is “suggests”. They have not yet directly seen any actual changes, such as changes between two images taken at different times.
Nonetheless, the data does point in the right direction. Moreover, it would be far more unlikely if nothing on Europa changed. The fundamental question that remains unanswered is how fast things change there. And we won’t have any chance to answer this question until Europa Clipper enters Jupiter orbit in 2030 and begins multiply fly-bys of Europa.

An evening pause: Performed live 2016. It ain’t some long-haired guy twiddling on a bass guitar, but her fingers as a nimble and as creative.
Hat tip Judd Clark.
To all: I am in need of more evening pause suggestions. If you have suggested before, you know the rules and the way to do it. Please send me stuff. If you haven’t suggested anything previously and have something you think would work, say so in a comment here — but don’t tell us what your suggestion is. I will email you to get it. The guidelines:
1. The subject line should say “evening pause.”
2. Please send only one suggestion per email.
3. Variety! Don’t send me five from the same artist. I can only use one. Pick your favorite and send that.
4. Live performance preferred.
5. Quirky technology, humor, and short entertaining films also work.
6. Suggestions should generally be short, less than 10 minutes, preferable under 5 minutes
7. Search BtB first to make sure your suggestion hasn’t already been posted.
8. I might not respond immediately, as I schedule these in a bunch.
9. Avoid the politics of the day. The pause is a break from such discussion.

A positive endgame in Gaza begins to loom
Israel food products, provided directly to Gazans.
Click for video.
Several news stories in the past few weeks suggest to me that we are beginning to see the first signs of the end game that will bring about the defeat of Hamas and the establishment of a sane society within the Gaza strip.
First, it appears that Hamas is short of cash, according to a news report from a Saudi newspaper and then re-reported by an Israeli news outlet.
Sources within the terror group revealed that Hamas is struggling to pay salaries — not only to government employees, but also to members of its military wing and staff in other affiliated bodies at all levels.
The sources added that the Izz ad-Din al-Qassam Brigades, Hamas’ military wing, have not paid salaries to terrorists for approximately three months and are facing serious financial difficulties in acquiring essential equipment for their military operations.
One of the things that has propped Hamas up for decades has been its control of foreign aid. The money comes in and Hamas doles it out while keeping large portions for its own use. The distribution of money gives Hamas leverage, while the money it keeps reinforces its power. Under Trump that foreign aid spigot has been largely shut down, and this story suggests we are now seeing the first results of this policy.
Second, Israel is now taking over the direct distribution of humanitarian aid. In the past Hamas maintained its power over its citizens by acting as the go-between of food and medicine. Nothing would go to anyone unless Hamas got its dirty hands on it first. Often no aid at all would reach Gazans. Hamas would keep it all, shipping it underground to its tunnels for use later during siege. Or it would sell that aid on the black market, raising money to fund its terrorist operations.
Israel, in partnership with the United States, is now ending that vile practice.

China launches its first asteroid sample return mission
China today successfully launched Tianwen-2, its first mission attempting to return a sample from a near Earth asteroid, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.
Video of the launch can be found here. The probe will take about a year to reach asteroid Kamo’oalewa, where it will fly in formation studying it for another year, during which time it will attempt to grab samples by two methods. One method 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.
Some data suggests Kamo’oalewa is possibly a fragment from the Moon, but that is not confirmed.
After a year studying Kamo-oalewa, Tienwen-2 will then return past the Earth where it will release its sample capsule. The spacecraft will then travel to Comet 311P/PANSTARRS, reaching it in 2034. This comet is puzzling because it has an asteroid-like orbit but exhibits activity similar to a comet.
As for the launch, there is no word where the Long March 3B’s lower stages and four strap-on boosters, all using very toxic hypergolic fuels, crashed inside China. It should be noted that the video I link to above was taken by an ordinary citizen watching from a hill nearby, bringing with him a group of children as well. Considering the nature of the rocket’s fuel (which can dissolve your skin if it touches you), China’s attitude is remarkably sanguine to not only drop these stages on its people, but to allow tourists to get so close to launches.
The leaders in the 2025 launch race:
65 SpaceX
31 China (with one more launch scheduled later today)
6 Rocket Lab (with one launch scheduled for today SCRUBBED)
6 Russia
SpaceX now leads the rest of the world in successful launches, 65 to 50.

The canyon that Curiosity will eventually climb
Click for full resolution. For original images go here and here.
Click for interactive map.
Cool image time! The panorama above, created from two photographs taken on May 23, 2025 by the left navigation camera (here and here) on the Mars rover Curiosity, looks south uphill into the canyon that Curiosity is eventually going to climb.
The overview map to the right provides the context. The blue dot marks Curiosity’s present position, the white dotted line its past travels, the red dotted line its initial planned route, and the green dotted line its future route. The yellow lines indicate the approximate area seen in the panorama above.
If you look on the horizon to the left, you can see very bright terrain higher up the mountain. This is the pure sulfate-bearing unit that is Curiosity’s next major geological goal. It won’t reach that terrain for quite some time however because first the scientists want to spend some time studying the boxwork geology that Curiosity is now approaching. That boxwork suggests two past geological processes, as yet unconfirmed. First it suggests the ground dried like mud, forming a polygon pattern of cracks that then hardened into rock. Second, lava seeped up from below and filled those cracks. The lava, being more resistant to erosion, ended up becoming the boxwork of ridges as the material around eroded away.
This proposed history however is not proven. They hope to find out when Curiosity gets there.
Meanwhile, despite having traveled almost 22 miles, the rover is more than 25 miles from the peak of Mount Sharp, which remains out of sight. That peak is also about 15,000 feet higher.

This proposed history however is not proven. They hope to find out when Curiosity gets there.
Meanwhile, despite having traveled almost 22 miles, the rover is more than 25 miles from the peak of Mount Sharp, which remains out of sight. That peak is also about 15,000 feet higher.
Scientists: Jezero Crater’s theorized lake overflowed intermittently four times in the past
Click for original image.
Scientists analyzing the Martian geology of the meandering outflow canyon from Jezero Crater, now think it was formed by four different very short-lived events when the theorized lake inside the crater overflowed the crater rim.
The map to the right, figure 1 of the paper (cropped and annotated to post here), provides the context. Two canyons, Sava Vallis and Neretva Vallis feed into Jezero Crater, and one canyon, Pliva Vallis, flows out. From the abstract:
By examining the shape of the valley, we noticed that Pliva Vallis was not like valleys carved by continuous rivers on Earth and propose instead that the valley was carved by at least four episodes of lake overflow. To give a minimum estimate of the duration of these events, we use a numerical model to simulate the overflow of a lake and the incision of a valley. Modeling suggests that the four (or more) episodes identified each incised part of the valley and that each episode lasted a few weeks at maximum.
The researchers also considered whether Pliva Vallis could have been carved by glacial flows, but rejected that possibility partly because “the general morphology of the valley shows a decrease in depth and width downstream, while subglacial channels [on Earth] tend to remain of similar width or become larger, as the flow regime does not decrease downstream.”
These conclusions of course carry a great deal of uncertainty. For one, they are based solely on orbital data. No ground truth exists as yet. Secondly, they assume the geology on Mars behaves in the same manner as on Earth. It could very well be for example that the reason the valley shrinks in size is because its Martian glacier sublimated away as flowed downhill, something that doesn’t happen on Earth.
Regardless, the data strongly suggests that water shaped Jezero in some manner.

Astronomers discover a star radiating in X-rays and radio in ways that fit no known explanation
ASKAP J1832 circled. Note the red arc denoting
the supernovae remnant. Click for original image.
Using both the Chandra X-Ray Observatory and the Square Kilometer Array in Australia, astronomers have discovered a star that pulses in both X-rays and and radio frequencies in a manner previously unseen and that fit no known theory.
ASKAP J1832 belongs to a class of objects called “long period radio transients,” discovered in 2022, that vary in radio wave intensity in a regular way over tens of minutes. This is thousands of times longer than the length of the repeated variations seen in pulsars, which are rapidly spinning neutron stars that have repeated variations multiple times a second. ASKAP J1832 cycles in radio wave intensity every 44 minutes, placing it into this category of long period radio transients.
Using Chandra, the team discovered that ASKAP J1832 is also regularly varying in X-rays every 44 minutes. This is the first time that such an X-ray signal has been found in a long period radio transient.
…However, that is not all ASKAP J1832 does. Using Chandra and the SKA Pathfinder, the team found that ASKAP J1832 also dropped off in X-rays and radio waves dramatically over the course of six months. This combination of the 44-minute cycle in X-rays and radio waves in addition to the months-long changes is unlike anything astronomers have seen in the Milky Way galaxy.
The false-color X-ray/radio image to the right shows the star (circled). Based on the data, it is unlikely that the star is a neutron star or a pulsar. Its properties also do not fit with a magnetar (a pulsar with a very strong magnetic field). Though located within a supernova remnant, the astronomers determined this to be a coincidence, the star unrelated to the remnant.
The best explanation so far is that this is a white dwarf with a companion and the strongest magnetic field ever conceived. The astronomers however do not appear enthused by that explanation either.

Engineers pinpoint and bypass fuel line problem on Psyche
Psyche’s flight path to the asteroid Psyche.
Click for original image.
In troubleshooting a significant drop in pressure in the xenon gas fuel lines to the ion engines of the Psyche asteroid probe, engineers have now pinpointed the problem to a failed valve and have switched to a back-up fuel line.
Powered by two large solar arrays, Psyche’s thrusters ionize and expel xenon gas to gently propel the spacecraft, which gradually picks up speed during its journey. The team paused the four electric thrusters in early April to investigate an unexpected drop in pressure. They determined that a mechanical issue in one of the valves, which open and close to manage the flow of propellant, caused the decrease. Through extensive testing and diagnostic work, the team concluded that a part inside one of the valves is no longer functioning as expected and is obstructing the flow of xenon to the thrusters.
Now that the swap to the backup fuel line is completed, engineers will command the spacecraft’s thrusters to resume firing by mid-June.
This issue had to be resolved before that scheduled firing in June or else Psyche would have fallen off its course to reach the metal asteroid Psyche by August 2029.

SpaceX launches Starship/Superheavy on ninth test flight, but experiences issues in orbit
Starship in orbit before losing its attitude control
SpaceX today was able to successfully launch Starship and Superheavy on its ninth test flight, lifting off from SpaceX’s Starbase spaceport at Boca Chica.
The Superheavy booster completed its second flight, with one of its Raptor engines actually flying for the third time. Rather than recapture it with the launchpad chopsticks, engineers instead decided to push its re-entry capabilities to their limit. The booster operated successfully until it was to make its landing burn over the Gulf of Mexico, but when the engines ignited all telemetry was lost. Apparently that hard re-entry path was finally too much for the booster.
Starship reached orbit and functioned successfully for the first twenty minutes or so. When engineers attempted a test deployment of some dummy Starlink satellites, the payload door would not open properly. The engineers then closed the door and canceled the deployment.
Subsequently leaks inside the spacecraft with its attitude thrusters caused the attitude system to shut down and Starship started to spin in orbit. At that point the engineers cancelled the Raptor engine relight burn. The spacecraft then descended over the Indian Ocean as planned, but in an uncontrolled manner. Mission control then vented its fuel to reduce its weight and explosive condition. It essentially broke up over the ocean, with data was gathered on the thermal system until all telemetry was lost.
Though overall this was a much more successful flight than the previous two, both of which failed just before or as Starship reached orbit, the test flight once again was unable to do any of its objectives in orbit. It did no deployment test, no orbital Raptor engine burn test, and no the re-entry tests of Starship’s thermal protection system. Obviously the engineers gathered a great deal of data during the flight, but far less than hoped for.
SpaceX has a lot of Superheavy and Starship prototypes sitting in the wings. I expect it will attempt its next flight test, the tenth, relatively quickly, by July at the very latest. I also do not expect the FAA to stand in the way. It will once again accept SpaceX’s investigative conclusions instantly and issue a launch license, when SpaceX stays it is ready to launch.
As Starship reached orbit as planned, I am counting this as a successfully launch. The leaders in the 2025 launch race:
64 SpaceX
30 China
6 Rocket Lab
6 Russia
SpaceX now leads the rest of the world in successful launches, 64 to 49.

Landing is still targeting June 5, 2025.
- South Korean rocket startup Innospace delays its first launch from July 2025 to second half of 2025
It appears they discovered issues with a first stage electric pump.

As always there is great uncertainty to these conclusions.

Supreme Court declines case of blacklisted student who declared “There are only two genders”, proving the large leftist blob is not going away no matter what Trump does
Liam Morrison, wearing the evil shirt that he wore the
second time teachers at Nichols Middle School sent
him home.
The Supreme Court today declined by a vote of 7-2 to hear the case of Liam Morrison, who as a 12-year-old was sent home from Nichols Middle School in Massachusetts because he wore a T-shirt that said “There are only two genders.” Later he came to school wearing the shirt in the picture to the right, and was sent home again.
Morrison and his parents sued, noting in their complaint that since the 1960s the courts have consistently ruled that students have free speech rights. However, in almost all those earlier cases the students were expressing views supportive of leftist causes, so of course their first amendment rights were aggressively protected by the courts.
Because Liam Morrison was taking a conservative rightwing position, however, the court now believes students like him are too young to have first amendment rights, and so of course he has been effectively silenced in school, permanently.
This case illustrates something that all freedom-loving Americans had better recognize. Just because Trump is shutting down whole agencies, firing hundreds of thousands of leftist government workers, denying federal funds to indoctrination universities like Harvard, we should not assume that all will be well in just a few years.

The Sun’s surface, in high resolution
Click for movie (though not of this image)
Cool image time! The picture to the right, reduced and sharpened to post here, was one of a number of pictures released today by the science team operating the new adaptive optics at the 60 inch Goode Solar Telescope (GST) at the Big Bear Solar Observatory (BBSO) in California. It shows the fluffy surface of the Sun, made of many needle-like threads called spicules, with larger bits of plasma (in the center) flung upward and back along the Sun’s magnetic field lines.
If you click on the image, you can watch a 42-second movie produced by many images of a different plasma blob as it changes and evolves. Other short movies produced show bits of this material falling back quickly along those field lines as well as that fluffy surface of needles waving almost like tall prairie grass. The width of the image covers approximately 25,000 miles, which means you could fit about three Earth’s in this space.
To create these images from a ground-based telescope required new technology:
The GST system Cona uses a mirror that continuously reshapes itself 2,200 times per second to counteract the image degradation caused by turbulent air. “Adaptive optics is like a pumped-up autofocus and optical image stabilization in your smartphone camera, but correcting for the errors in the atmosphere rather than the user’s shaky hands,” says BBSO Optical Engineer and Chief Observer, Nicolas Gorceix.
Using this refined imagery, solar scientists will be better able to track and observe the Sun’s small scale behavior (actually quite large on human scales).

Live stream of Elon Musk’s speech to SpaceX employees today
FINAL UPDATE: It appears his talk has been called off, for the present. I suspect he wants a better idea what happened on today’s flight before speaking.
UPDATE: It appears Musk has rescheduled his speech for 6 pm (Central) tonight, after the launch of the ninth test flight of Starship/Superheavy. The embedded live stream below is for this rescheduled broadcast.
I have embedded below the Space Affairs live stream of Elon Musk’s speech that he plans to give to his SpaceX employees today at 10 am (Pacific) today. Musk has entitled it “The road to making life interplanetary.” He has already indicated that he will outline in more detail SpaceX’s program for getting Starship/Superheavy operational, including the likelihood of test flights to Mars in the near future.

“Was this trip necessary?”
An evening pause: On Memorial Day, let’s revisit an evening pause from 2011 of one short scene from the William Wellman film, Battleground (1949), to remind us why sometimes it is necessary to fight a war.
The saddest thing about this clip is how ugly it makes too many modern Americans look, for they have adopted the certain, ignorant, and bigoted aspects of the totalitarians from the 1930s and 1940s that the generation then fought so hard to defeat. Today’s American totalitarians — almost all of whom are on the left — are certain that because Donald Trump is doing things they disagree with, he along with all of his supporters should be killed. No debate is permitted. They are right and anyone who challenges them is evil.
Memorial Day is not simply about remembering the dead so that they will not have died in vain. It is also about remembering why they died.
The real reason we celebrate Memorial Day
To the right is another cool image, but this one has nothing to do with astronomy, though you will likely be hard pressed to figure out exactly what you are looking at without some study. It is clearly some broken metal object inside a forest, but identifying its exact nature is not obvious.
What you are looking at is the remains of a propeller plane (likely flown on a reconnaissance mission) that crashed in the jungles of Vietnam during that long and tragic war of the 1960s and 1970s. Most amazingly, despite its twisted nature, the pilot survived and was fortunately quickly rescued by American troops before the arrival of the Vietcong.
That pilot’s name was Francis James Floyd. His son Jeffrey, a regular reader of Behind the Black, sent me the picture to illustrate that guys who fly wingsuits are not the only ones willing to do crazy things in the air. As he wrote,
Our dad fought in WWII, Korea and Vietnam as an Air Force pilot. While he had to learn how to parachute jump, he hated it. Even if the engine(s) failed, as long as he had his wings attached, he would not exit (jump). He said “There are two kinds of people that jump out of airplanes: idiots, and people in the armed services.”
So, the attached photo is what was left of his plane in Vietnam. He used the tops of the forest trees to try to slow down, like skimming the water. Fortunately, the good guys reached him first, and he came home.
Francs Floyd however was not an exception or rare thing, like the wingsuit fliers are today. He was one of a massive generation of Americans who, after the Japanese attack on Pearl Harbor on December 7, 1941, quickly enlisted to defend the United States and — more importantly — its fundamental principles of freedom and limited government.
Floyd was only twenty when he enlisted in 1942. He had no flight experience, but was quickly trained to become a pilot who flew fighter bomber missions over Italy. Later he returned to fly in the Korean War, and then again in Vietnam. As his son adds,

A galactic pinwheel
Click for original image.
It’s cool image time, partly because we have a cool image and partly because there is little news today due to the holiday. The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope and was released today as the science team’s picture of the week. It shows us a classic pinwheel galaxy located approximately 46 million light years away. From the caption:
A spiral galaxy seen face-on. Its centre is crossed by a broad bar of light. A glowing spiral arm extends from each end of this bar, both making almost a full turn through the galaxy’s disc before fading out.
The bright object with the four spikes of light is a foreground star inside the Milky Way and only 436 light years away. The bright orange specks inside the spiral arms are likely star forming regions, with the blue indicating gas clouds.
As for the holiday, I’ll have more to say about Memorial Day later today.

Cargo Dragon splashes down and is recovered successfully
A SpaceX cargo Dragon capsule was recovered successfully earlier today after it splashed down off the coast of California.
The spacecraft carried back to Earth about 6,700 pounds of supplies and scientific experiments designed to take advantage of the space station’s microgravity environment after undocking at 12:05 p.m., May 23, from the zenith port of the space station’s Harmony module.
Some of the scientific hardware and samples Dragon will return to Earth include MISSE-20 (Multipurpose International Space Station Experiment), which exposed various materials to space, including radiation shielding and detection materials, solar sails and reflective coatings, ceramic composites for reentry spacecraft studies, and resins for potential use in heat shields. Samples were retrieved on the exterior of the station and can improve knowledge of how these materials respond to ultraviolet radiation, atomic oxygen, charged particles, thermal cycling, and other factors.
Other cargo returned included a robot hand that tested its grasping and handling capabilities in weightlessness, as well as other experiments.
The capsule itself spent three months in orbit after launching at the end of April.
