Hubble data detects persistent water vapor on one of Europa’s hemispheres
Using data from the Hubble Space Telescope spanning sixteen Earth years, scientists have detected the presence of water vapor on Europa, but strangely spread only across one of the moon’s hemispheres.
Previous observations of water vapor on Europa have been associated with plumes erupting through the ice, as photographed by Hubble in 2013. They are analogous to geysers on Earth, but extend more than 60 miles high. They produce transient blobs of water vapor in the moon’s atmosphere, which is only one-billionth the surface pressure of Earth’s atmosphere.
The new results, however, show similar amounts of water vapor spread over a larger area of Europa in Hubble observations spanning from 1999 to 2015. This suggests a long-term presence of a water vapor atmosphere only in Europa’s trailing hemisphere – that portion of the moon that is always opposite its direction of motion along its orbit. The cause of this asymmetry between the leading and trailing hemisphere is not fully understood.
First, it must be emphasized that the amounts of atmospheric water being discussed are tiny, so tiny that on Earth we might consider this a vacuum.
Second, that the water vapor is only seen on the trailing hemisphere suggests there is some sort of orbital influence involved, though what that influence is remains unknown.
Hopefully when Europa Clipper finally arrives in orbit around Jupiter in 2030, with a path that will fly past Europa fifty times, we will some clarity on these questions.
A gecko on Mars

Today’s cool image is also today’s picture of the day from the science team of the high resolution camera on Mars Reconnaissance Orbiter (MRO. That picture, rotated, cropped, and reduced to post here, can be seen to the right. As the caption authors Sharon Wilson and Sarah Sutton write:
The smooth volcanic surfaces in the Gordii Fossae region are sometimes interrupted by long, narrow troughs, or fissures. These fissures form when underground faults, possibly involving magma movement, reach the near-surface, allowing material to collapse into pits or an elongated trough. This fissure appears to have erupted material that flowed onto the surface.
If you use your imagination, this trough resembles a gecko with its long tail and web-shaped feet!
This impression is even more evident in the wider image taken by MRO’s context camera below.

Today’s blacklisted American: Thomas Jefferson blacklisted by NY mayor de Blasio
Thomas Jefferson, banned by New York’s Democrats
The modern dark age: A commission appointed by New York’s Democratic Party mayor, Bill de Blasio, which is also headed by his wife, has quietly moved to remove a statue of Thomas Jefferson from the city’s council chambers, where it has stood since 1834.
The city is apparently going to indefinitely loan the statue — which is a plaster copy of the original that presently stands in the Rotunda of the Capitol in Washington — to the New-York Historical Society. The present plans call for it to be removed by October 21st, well before de Blasio leaves office at the end of this year.
The explanation for this action by Councilman I. Daneek Miller (D-Queens) illustrates well the level of hate and ignorance about the United States and its noble history by our modern so-called elite:
“There’s so much about Thomas Jefferson and his own personal writings, memoirs about how he treated his slaves, his family members and things of that nature and how he perceived African Americans and slaves — that they lacked intelligence, that they were not to assimilate into society,” Miller told The Post.
As someone who has read all of Jefferson’s writings, I can tell you that Miller is an ignorant fool, who is expressly cherry-picking phrases from Jefferson to create a false slanderous picture of the man. Miller might be better to go to the Jefferson Memorial in Washington and read the words inscribed there:

Shatner vs today’s America
Shatner, on the left, turns away from Bezos and the spray of champagne.
Capitalism in space: The profound, emotional, and thoughtful reaction of William Shatner to his short suborbital flight yesterday on Blue Origin’s New Shepard space capsule contrasted starkly with the crass, rude, and shallow response of his co-passengers and Jeff Bezos.
You can watch Shatner’s comments right after landing at the video at the link. Watch how he tries to express his thoughts to Bezos immediately, and is almost ignored as Bezos and the others instead want to spritz champagne at each other. Shatner turns away, almost in disgust. The screen capture to the right shows him turning away, not because he doesn’t want to be hit by champagne but because he doesn’t want that shallowness to steal from him the emotions he now feels.
Eventually Bezos realizes Shatner is going to say his peace, and that he better pay attention. Shatner, almost in tears, struggles to note how shocked he was at the relative thinness of the atmosphere. To him, the rocket so quickly zipped out of a blue sky into blackness. As he said,
“This air, which is keeping us alive, is thinner than your skin. It’s a sliver. It’s immeasurably small when you think in terms of the universe.
…”What you have given me is the most profound experience I can imagine. I’m so filled with emotion about what just happened … it’s extraordinary. I hope I never recover, that I can maintain what I feel now. I don’t want to lose it. It’s so much larger than me and life.”
Shatner is an actor. For him, the emotion is the most important thing, as that is what he has specialized in expressing on screen to others for his entire life. At this moment, however, he was not expressing the emotions of a imaginary character he was creating on screen, but his own personal emotions. He managed to do it, in the best way possible. God speed William Shatner. We shall miss you when you are gone.
That Bezos was so unprepared for this moment from Shatner was very unfortunate. It made him look very shallow and foolish, which is a shame because, as Shatner so correctly noted, Bezos was the one who made that moment possible.
Shatner, at ninety years of age, is of a different more civilized generation that believed strongly in applying thought to one’s emotions, rather than letting those emotions rule. The contrast between him and all the younger people in this clip gives us a clear snapshot of an America now gone, replaced by the thoughtless emotional America of today.
Russia launches another 36 OneWeb satellites
A Russian Soyuz-2 rocket today successfully launched 36 more OneWeb satellites, raising the total of the satellite constellation in orbit to 358.
The launch was from Russia’s new spaceport Vostochny. As with all launches from Russia, the expendable first stage core and strap-ons landed inside Russia within designated drop zones. And as usual, no word from Russia on whether they landed on anyone’s head.
The leaders in the 2021 launch race:
34 China
23 SpaceX
17 Russia
4 Northrop Grumman
The U.S. still leads China in the national rankings, 35 to 34. With launches scheduled by both countries (two by the U.S. and one by China) over the next three days, these numbers will continue upward.

Webb telescope finally arrives at launch site in French Guiana
After almost twenty years of construction (a decade behind schedule) and a cost of $10 billion, ($9.5 billion over budget), the James Webb Space Telescope today arrived at the processing facility at Arianespace’s French Guiana spaceport, where it will be prepared for a December 18, 2021 launch on an Ariane 5 rocket.
Once launched the telescope, which is not a replacement for Hubble because it observes in the infrared (not optical) and is optimized for deep space cosmology, will take two weeks to reach its orbital position about a million miles from Earth, as shown in the graphic.
Let us all cross our fingers and toes that it all works as designed, for if it doesn’t this will be the biggest failure ever in the history of NASA.
Astronaut blood samples suggest long-term exposure to weightlessness causes brain damage
New research comparing blood samples taken from five Russian astronauts before and after long term missions to ISS suggests that weightlessness can cause brain damage.
Published in JAMA Neurology, the new research looked at five male Russian cosmonauts. Each spent an average of 169 days in space. Blood samples were taken from each subject before leaving Earth, and then at three points after returning.
Five different blood-based biomarkers were measured, each known to correlate with some kind of brain damage. Three biomarkers in particular were found to be significantly elevated after the cosmonauts returned to Earth – neurofilament light (NfL), glial fibrillary acidic protein (GFAP), and a specific type of amyloid beta protein.
The researchers hypothesize the increases in NfL and GFAP levels may indicate a type of neurodegeneration called axonal disintegration. Elevated NfL levels are currently being investigated as a way of detecting the earliest stages of brain damage associated with Alzheimer’s disease.
It must be emphasized that the research did not find brain damage, only data within the blood samples that is often associated with brain damage. More research is required to determine if these biomarkers indicate the same thing in space as they do on Earth.
Today’s blacklisted American: Brownstone Institute blackballed by LinkedIn for associating with famed Harvard epidemiologist
They’re coming for you next: The non-profit Brownstone Institute, founded in 2021 to provide an outlet for educated dissent on science and economic issues, has found itself repeatedly censored by LinkedIn in the past two weeks because one of its founders is famed Harvard epidemiologist Martin Kulldorff.
If you are a regular reader of this column you might remember Kulldorff’s name. He was blacklisted by the CDC, Twitter, and LinkedIn in late August because he dissents from the oppressive lockdown policies those organizations advocate. He was also one of the leading authors of the Great Barrington Declaration [also available here a pdf], which strongly opposes the policies of lockdowns, mandates, and the other totalitarian actions taken by governments since 2020, and instead calls for the more traditional (and successful) “focused” approach for dealing with epidemics and diseases: Protect the vulnerable (the old and sick) from the disease while letting everyone else (the young and healthy) live normal lives and thus get infected quickly, become immune, and thus squelch off the virus.
Kulldorff is also one of the world’s preeminent experts on vaccine safety and “helped develop the CDC’s current system for monitoring potential vaccine risks.”
Anyway, it appears that on October 1st, LinkedIn suddenly discovered that Kulldorff was one of the senior scholars at the Brownstone Institute, and began deleting the institute’s posts.

Australia to build unmanned lunar rover for NASA
NASA and Australia have signed a deal whereby Australia will provide an unmanned lunar rover on which NASA will put its science instruments, with the package taken to the Moon by a commercial lander.
As part of the agreement, a consortium of Australian businesses and research organizations will develop a small rover that can operate on the lunar surface. The rover would have the ability to pick up and transfer lunar regolith (broken rock and dust) to a NASA-operated in-situ resource utilization (ISRU) system on a commercial lunar lander. Such a rover could fly to the Moon as early as 2026.
While this agreement helps widen the competition in the commercial unmanned planetary aerospace industry, it does so by helping the industry of another country. This policy fits the general philosophy of the Democratic Party and the Biden administration, which generally focuses on aiding other countries before the U.S.

Watching the New Shepard suborbital flight with William Shatner
I have embedded the live stream of the Blue Origin suborbital flight today of its New Shepard spacecraft, carrying four passengers including William Shatner.
The launch is presently scheduled for 7 am (Pacific). The live stream will start about 5:30 am (Pacific).
As I have noted previously, the announcers for Blue Origin tend to blather quite a bit, hyping the situation to a point of nausea. Hopefully during the flight they will shut up and allow the voices of the passengers to take center stage.
I meanwhile will be on the road during the flight. I will try to post updates as well as my normal news stories, but both might have to wait until I return home in the early afternoon. Regardless, the live stream is below for you to enjoy.
