Unidentified astronaut from recent ISS mission released from hospital

9:54 am

Though NASA’s press release provided little informationto protect the astronaut’s privacy, including his or her name, the unidentified astronaut who was held overnight for observation after returning from a seventh-month stay on ISS mission has now been released from the hospital.

After an overnight stay at Ascension Sacred Heart Pensacola in Florida, the NASA astronaut was released and returned to NASA’s Johnson Space Center in Houston Saturday. The crew member is in good health and will resume normal post-flight reconditioning with other crew members.

This has happened before. Readapting to a 1G environment after months in weightlessness can be difficult, even if one does all the exercises required while in orbit.

SpaceX yesterday launched another 23 Starlink satellites

5:34 pm

SpaceX yesterday successfully launched 23 more Starlink satellites, its Falcon 9 lifting off from Cape Canaveral in Florida.

While the video link above says 23, a UPI report said the launch placed 22 satellites in orbit. I have no idea which is right, as the number of Starlinks on these launches range from 20 to 23.

The first stage completed its 19th flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

105 SpaceX
48 China
11 Russia
11 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 122 to 71, while SpaceX by itself now leads the entire world, including American companies, 105 to 88.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Space News buries the lede

9:42 am

In reporting the information revealed in an audio report of two SpaceX engineers to Elon Musk, Space News completely misses the main reason Musk posted this video.

The focus of Jeff Foust’s report is the technical problems the engineers revealed that occurred during the descent of Superheavy during the last flight. According to them, one particular parameter related to the Raptor engines was one second away from demanding an abort, whereby the rocket would not attempt to be captured by the tower chopsticks but instead crash along side it. In addition, these engineers reported the worrisome consequences when a chine on the booster ripped off shortly before landing.

All interesting, but the real reason Elon Musk posted this clip from a much longer audio report is what one engineer says about two thirds of the way through:

Given that that is the first launch [#6] in a long time — well, really, ever — that we’ve not been FAA driven, we’re trying to go do a reasonable balance of speed and risk mitigation on the booster, specifically.

Musk wished everyone to know without question the perspective of his employees when it comes to the red tape of the FAA. It hasn’t been our imagination. For the past three years the FAA has determined the test schedule, slowing it down significantly while costing SpaceX a lot of money.

Space News, which generally has been in the tank for the regulators and the FAA, puts this quote to the very end of its article, almost as an aside. I suspect the outlet would have liked to leave it out.

I have posted the video below, so my readers can listen at their leisure.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

One unidentified astronaut hospitalized after return to Earth today

9:04 pm

Though NASA has released very little information, including the indentity of the astronaut, one of the four crew who were brought back to Earth early today has ended up in the hospital.

NASA said Friday one its astronauts is in a hospital in Florida for medical observation after a “normal” predawn splashdown in the Gulf of Mexico inside a SpaceX capsule.

The mission’s other three crew members were cleared to return to their home base at Johnson Space Center in Houston after their own medical evaluations, NASA said.

The hospitalized astronaut “is in stable condition and under observation as a precautionary measure,” a NASA spokesperson said in a statement. The agency did not identify the astronaut or provide any more details about their condition, citing medical privacy protections.

That the other three astronauts returned to their home base at Johnson in Houston strongly suggests the hospitalized astronaut is the one Russian, Alexander Grebenkin, Normally Russians head back to Russia relatively quick after landing.

This remains speculation. We will have to wait for more information.

Gina Lollobrigida – Pagan dance

6:01 pm

An evening pause: I think this makes a great start to the weekend. Clips from the 1959 movie Solomon and Sheba, centered on Gina’s pagan dance as Sheba, and edited to a piece of music by Dead Can Dance, called Cantara, which the youtube website labels “genuinely pagan music.” If you want to see the original film, go here and go to about 90 minutes. In the original, God steps in to stop all this hanky-panky.

Taking the day off…

12:19 pm

Yesterday I came down with a head cold, which is draining me of energy. I am going to take a few hours off to take a nap. I should post some more later in the day but don’t expect much.

A sidenote: When I mentioned I had a head cold to someone, the first question that person asked was “Covid?” I laughed and responded, “Who cares? Covid has been nothing more than a cold since around 2021.”

This obsession with Covid has got to stop. From a infectious disease perspective the only valuable thing it taught us is that every new and harsh flu strain that comes through eventually mutates downward utnil it is nothing more than the common cold. Covid did exactly that, no matter how much the Chicken Littles of the world tried to claim otherwise.

Boeing considering selling its space division

11:55 am

According a Wall Street Journal exclusive today (behind a paywall), the company is now exploring the possibility of selling off its space division.

The NASA business that Boeing is exploring a sale of includes the troubled Starliner space vehicle and operations that support the International Space Station, but excludes the unit building NASA’s Space Launch System, the newspaper reported.

The U.S. planemaker’s shares rose 0.6% in afternoon trading.

Boeing’s space division includes its Starliner capsule and its work on NASA’s SLS rocket, as well as building many of the modules on ISS and operating it for NASA.

If this is so, it appears the new CEO, Kelly Ortberg, has decided that in order to get the company back on track it needs to focus on Boeng’s first and central business, building airplanes. Space is a distraction that is not helping the company bottom line right now in any way. Furthermore, NASA in 2020 told Boeing it would not entertain any new project bids from the company because its past bids were so poorly conceived. That decision remains in effect now, four years later. Since then Boeing has only have gotten a renewal contract to build more SLS rockets, plus a contract to develop a new airplane wing, but little else.

Using spectroscopic data, astronomers create 3D map of ancient supernova remnant

10:55 am

Supernova 1181
Click for original image.

Astronomers have now createdsdft a 3D map of the remnant formed by a supernova that occurred in 1181, using detailed spectroscopic data to determing which remnant filaments are moving towards us and which are moving away.

The picture to the right is from figure 1 of their paper, and shows how the filaments radiate out from the center in straight lines, something that is unusual for such remnants. It was taken in 2023 by a ground-based telescope at Kitt Peak in Hawaii. From simple optical data it is impossible however to determine which filaments are in the rear, expanding away from us, and which are in the front, expanding towards us.

To probe the three-dimensional structure of the supernova remnant, the astronomers turned to KCWI, an instrument that can capture multiwavelength, or spectral, information for every pixel in an image. This is like breaking apart the light captured in every pixel into a rainbow of colors. The spectral information enabled the team to measure the motions of the filaments poking out from the center of the explosion and ultimately create a 3D map of the structure. The filament material that is flying toward us shifted toward the blue higher-energy portion end of the visible spectrum (blue-shifted), while light from material moving away from us shifted toward the red end of the spectrum (red-shifted).

…The results showed that the filament material in the supernova is flying outward from the site of the explosion at approximately 1,000 kilometers per second. “We find the material in the filaments is expanding ballistically,” says Cunningham. “This means that the material has not been slowed down nor sped up since the explosion. From the measured velocities, looking back in time, you can pinpoint the explosion to almost exactly the year 1181.”

The 3D information also revealed a large cavity inside the spindly, spherical structure in addition to some evidence that the supernova explosion of 1181 occurred asymmetrically.

Using this data, they were able to create that 3D map, shown below in a coarse animation video.

Sutherland spaceport submits another revised plan to local council

10:41 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea.

We’re from the government and we are here to help you! The long-delayed proposed Sutherland spaceport on the north coast of Scotland has now submitted another revised plan to its local Highlands council for approval.

The amended plans for Sutherland Spaceport include a smaller launch pad and launch services facility, and realigning an access road to avoid an area of deep peat. Highland Council planners said the changes would mean reducing the amount of peat that would have to be excavated by more than half. The soil is seen as important because it absorbs CO2.

Highland councillors meeting next week have been asked to approve the amendments. In a report, officials said the amount of peat to be dug up could be cut from 24,046 cubic metres to 9,895 cubic metres.

This is the second time the spaceport has had to submit revised plans to this council. It did so in December 2023, but apparently the council was not satisfied.

Meanwhile Sutherland’s main launch customer, Orbex, has still not gotten its launch licence from the UK’s Civil Aviation Authority, first applied for in February 2022. Orbex, which has a fifty year lease at Sutherland and has built its rocket factory nearby, had planned to do its first test launch of its Prime rocket two years ago. Didn’t happen.

Adding to these bureaucratic delays, Anders Holch Povlsen, a local billionaire — who is an investor in the Saxaford spaceport on the Shetland Islands — in July 2024 filed what appeared to be an absurd harrasment lawsuit against Sutherland, and this was the second time he had done so.

I think Orbex picked the wrong spaceport horse in this race, and is likely going to be killed by this red tape and opposition.

The uncertainty of science: New research suggests first image in ’22 of Milky Way’s central black hole is likely not accurate

10:25 am

Sagittarius A*
The original interpretation. Click for full image.

The new interpretaion
The new asymmetrical interpretation. Click for original image.

Surprise, surprise! A new analysis of the data behind the 2022 false-color radio image of the supermassive black hole at the center of the Milky Way, posted to the right, suggests that image was not accurately interpreted from the data.

Astronomers led by the National Astronomical Observatory of Japan (NAOJ) say their analysis points at Sagittarius A* having an elongated accretion disk, as opposed to the ring-like “doughnut” image released in 2022 by an international team called the Event Horizon Telescope (EHT) collaboration.

The EHT image shows a central dark region where the hole resides, circled by the light coming from super-heated gas accelerated by immense gravitational forces.

But a new paper published today in Monthly Notices of the Royal Astronomical Society suggests that part of this appearance may actually be an artefact because of the way the image was put together. … Assistant professor Miyoshi Makoto, of the NAOJ, said: “Our image is slightly elongated in the east-west direction, and the eastern half is brighter than the western half. We think this appearance means the accretion disk surrounding the black hole is rotating at about 60 per cent of the speed of light.” He added: “Why, then, did the ring-like image emerge? Well, no telescope can capture an astronomical image perfectly. We hypothesise that the ring image resulted from errors during EHT’s imaging analysis and that part of it was an artefact, rather than the actual astronomical structure.”

It must be noted that this false color radio image was assembled from eight different radio telescopes across the globe, and to bring the data together required a great deal of massaging. While most astronomers appear to favor the top picture, it is just as likely that the bottom picture is a better representation. Either way, both must be considered in any future studies of Sagittarius A*’s environment and structure.
