China today finally brought its damaged Shenzhou-20 manned capsule back to Earth, having it touch down in China’s Inner Mongolia Autonomous Region.

All the text sources from China’s state-run press showed images like the one to the right, from a distance. Though one of the descent capsule’s windows is visible, and appears to have attracted a lot of attention from members of the recovery crew, it is impossible to see if this is the window that China says was hit by some space debris and damaged. Nor can we see the cracks China claimed were there that forced it to send up a rescue capsule to bring the crew back and return this capsule unoccupied.

BtB’s stringer Jay found two other tweets that China released on X. One focused entirely on the used spacesuit that was returned within the capsule, ignoring the capsule itself. The other showed just one image, showing a side of the capsule with no windows.

Why China has been so reluctant to release any images of the damaged window forces one to suspect they are hiding something, such as the cracks were not caused by an impact but by some issue with the capsule itself. This speculation could of course be completely wrong, but China’s secrecy is what generates it.

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

SpaceX yesterday completed one launch while China had two launch failures

8:20 am

There were three launches attempts yesterday, though the two by China were both failures.

First, China’s Long March 3B rocket attempted a launch from its Xichang spaceport in southwest China but the rocket failed at some point. All that China’s state-run press said was that “an anomaly occurred during its flight” and “the cause of the failure is under investigation.” We therefore do not know when the failure occurred, or where any of the rocket stages crashed, inside China or elsewhere.

Next, China’s pseudo-company Galactic Energy attempted the first launch of its new Ceres-2 rocket, lifting off from the Jiuquan spaceport in northwest China. Once again, China’s state-run press provided little information, stating merely that “an anomaly occurred during its flight.”

The Ceres-2, like its predecessor the Ceres-1, is a solid-fueled rocket, though its final stage upgrades the rocket with liquid fuel. Both are based on missile technology, which is why this pseudo-company is “pseudo,” as everything it does is closely supervised by the Chinese government.

Finally, SpaceX placed a National Reconnaissance Office classified satellite into orbit, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its 2nd flight, landing back at Vandenberg. The two fairings in turn completed their 13th and 30th flights respectively.

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.

Mars Reconnaissance Orbiter’s high resolution camera is showing its age

10:53 am

More data drop-outs from MRO

In a cool image earlier this week I noted that, in going through the archive of images most recently sent back from Mars Reconnaissance Orbiter’s (MRO) high resolution camera, it appeared the camera was exhibiting more anomalies, and that we must therefore “be prepared for the loss of this camera and orbiter in the somewhat near future.”

In reviewing the archive again yesterday I noticed even more evidence of deterioration, as illustrated by the picture to the left. Not only are there blank vertical strips of no data, but the color drops out of the color strip halfway down, something I had never seen before. Nor was this the only picture with these issues.

I decided to email Alfred McEwen of the Lunar & Planetary Laboratory in Arizona. who until recently had been the camera’s principal investigator, to find out what is really going on. His answer:

Yes, HiRISE is getting old, just like us. There are 2 issues:

  • 1. Sometimes RED4 fails, leaving a gap in the RED products and color.
  • 2. Bit flips create bad pixels (zeros) in RED1_1 and RED3_1. This can still be mitigated by raising electronics temperatures, and we were just approved for an increase, so this problem should soon be reduced for a year or two. One problem with these increased temperatures is that our calibration isn’t correct, leading to the stripe-ing and strange colors that you noted, although dusty air can also create such issues. The calibration will eventually get updated, but funding is extremely tight.

The first issue explains the drop-out in the color strip. This appears to be a relatively new problem.

The second issue explains the two additional black strips to the right of the color strip. (Bit flips are cases where the radiation of space causes a binary bit to flip randomly from 0 to 1, or visa versa.) Bit flips are something engineers expect in spacecraft, but it appears on MRO they are occurring with more and more frequency.

A third issue, the failure of the electronics unit for CCD RED4 that occurred in August 2023, causes a loss of data in the color strip (see the b&w version of the image above for an example), which the camera team has compensated for using other color filters in that area.

According to McEwen, while the team seems confident the increased temperatures, combined with re-calibration, will fix or reduce issue #2, it is less confident about its impact on the camera’s lifespan.

We wish we knew. We’ve raised temperatures many times and it still works, so we keep raising temperatures incrementally just in case.

All in all, however, McEwen says he expects the high resolution camera to be able to produce images for at as long as MRO operates (at least a decade more), though with time we might be finding the images become narrower and narrower strips.

Astronomers detect a bar of iron in the center of the Ring Nebula

The uncertainty of science: Using a new instrument on the Herschel Telescope in Chile, astronomers have detected a bar of iron cutting across the hole in the center of the Ring Nebula. You can read their paper here.

The cloud of iron atoms, described for the first time in Monthly Notices of the Royal Astronomical Society, is in the shape of a bar or strip: it just fits inside the inner layer of the elliptically shaped nebula, familiar from many images including those obtained by the James Webb Space Telescope at infrared wavelengths. The bar’s length is roughly 500 times that of Pluto’s orbit around the Sun and, according to the team, its mass of iron atoms is comparable to the mass of Mars.

The bar does not cross the nebula’s central star, nor does it exhibit the kind of motion seen by jets flowing outward from such stars. From the paper’s conclusion:

At present, there seem to be no obvious explanations that can account for the presence of the narrow ‘bar’ of [Fe v] and [Fe vi] emission seen in our WEAVE spectra to extend across the central regions of the Ring Nebula. Fresh observations of this newly uncovered feature at much higher spectral resolution seem essential to make progress

The scientists toss out the possibility that the bar is the remains of a rocky planet vaporized at some point in the system’s past, but that is simply a wild guess.

The recent computer hack of the European Space Agency was bigger than it admitted

9:00 am

After the European Space Agency (ESA) claimed in December that a computer hack that stole about 200 gigabytes of data was “limited,” it turns out that the agency had been hacked more than once preveious this past fall, and that the data stolen was far larger and apparently not limited at all.

The European Space Agency on Wednesday confirmed yet another massive security breach, and told The Register that the data thieves responsible will be subject to a criminal investigation. And this could be a biggie.

Earlier in the week, Scattered Lapsus$ Hunters told us that they gained initial access to ESA’s servers back in September by exploiting a public CVE, and stole 500 GB of very sensitive data. This, we’re told, includes operational procedures, spacecraft and mission details, subsystems documentation, and proprietary contractor data from ESA partners including SpaceX, Airbus Group, and Thales Alenia Space, among others.

And, according to the crims, the security hole remains open, giving them continued access to the space agency’s live systems.

“ESA is in the process of informing the judicial authorities having jurisdiction over this cyber incident to initiate a criminal inquiry,” an ESA spokesperson said via email. The agency declined to answer The Register’s specific questions about the intruders’ claims.

The article at the link outlines a slew of other hacks at ESA over the last decade. The agency seems unable to clean up its act.

China launches four satellites for another Chinese constellation

8:41 am

The Chinese pseudo-company Galactic Energy early today successfully launched another four satellites in the Tianqi satellite constellation, its Ceres-1 solid-fueled rocket lifting off from a sea platform off the northeast coast of China.

This was the sixth launch for the Tianqi constellation, which apparently is an internet-of-things constellation. It has launched 41 satellites so far, though only 29 are presently operational, with 12 having had their orbits decay.

French rocket startup MaiaSpace wins ten-launch contract from Eutelsat

8:01 am

The French rocket startup MaiaSpace, which has not yet launched anything, has won a ten-launch contract from Eutelsat to place an unspecified number of its next generation OneWeb satellites into orbit.

Eutelsat has ordered around ten launches from MaiaSpace to launch some of the 440 new OneWeb satellites. These launches are scheduled from late 2027 to 2029. MaiaSpace has thus secured 50% of the launches planned for this period.

MaiaSpace is a wholly owned subsidiary of ArianeGroup, the company that builds Arianespace’s Ariane-6 rocket. ArianeGroup created it when it realized the expendable Ariane-6 rocket was not going to do well competing with the new reusable rockets. MaiaSpace’s Maia rocket will launch from French Guiana, and is being designed to eventually be reusable.

What makes this deal puzzling is that MaiaSpace is far behind at least thee other rocket startups in Europe, Germany’s Isar Aerospace and Rocket Factory Augsburg, and Spain’s PLD, all of which are much closer to an orbital launch. I suspect ArianeGroup used its clout to win the contract.

Chris Rea – The Road To Hell

6:01 pm

An evening pause: Performed live 2006.

Hat tip Alec Gimarc, who adds these details: “Chris Rea passed away last week. About our age. Over 30 studio albums. British. Very much an acquired taste. Been listening to him for nearly 40 years. Smooth, smoky voice. He specialized in slide guitar. Road to Hell is probably his greatest hit.”
