UAE to train astronauts at NASA

9:29 am

The United Arab Emirates has signed an agreement with NASA to train its two future astronauts to ISS.

UAE astronauts Hazzaa AlMansoori and Sultan AlNeyadi have already begun their training at Nasa’s Johnson Space Center in Houston starting Monday, Salem AlMarri, head of the UAE Astronaut Programme, at the Mohammed Bin Rashid Space Centre (MBRSC), said during a media briefing. AlMansoori and AlNeyadi had earlier trained at the Yuri Gagarin Cosmonaut Training Center in Star City, Moscow, in September 2018 as part of their preparation for their launch to the ISS.

The two men will be launched to ISS by Russia using its Soyuz rocket and capsule. However, the UAE is smart to get them training in the U.S., as they need to work with U.S. mission control and U.S. systems on ISS. Moreover, I expect the UAE might wish to buy tickets eventually on either Dragon or Starliner, and this training lays the groundwork for that possibility.

Ryugu, like Bennu, appears to have rocks from other asteroids

9:21 am

Japanese scientists today announced that 21 rocks identified by Hayabusa-2 on the asteroid Ryugu have a composition that suggests they were formed on another asteroid.

Although Ryugu’s surface is uniformly dark [because it is a C-type asteroid], the scientists behind the new research found numerous boulders scattered across the asteroid that were 1.5 or more times brighter than their surroundings — that is, they reflected at least 50% more light than most of the rest of Ryugu. This contrast made the researchers suspect these boulders may have come from outside the asteroid.

By analyzing the spectrum of light reflected off 21 of these boulders, the scientists deduced they were made of minerals known as anhydrous silicates. Prior studies have suggested that such water-poor, silicon-rich rocks make up silicaceous or S-type asteroids, the most common kind of asteroid found in the inner main asteroid belt. The brightness of these boulders also matches the brightness of S-type asteroids.

This result compliments the result yesterday from scientists studying Bennu with OSIRIS-REx, and was in fact released at the same time. Both asteroids apparently contain material from other asteroids, suggesting that asteroids in their initial formation (as rubble piles) are routinely a mixture of material from many asteroids, thrown out during impacts and then recaptured.

Despite fading epidemic governments vow to maintain lockdowns

2:52 pm

Graph of U.S. deaths day to day through September 21, 2020

The lockdowns will never end: Despite the continuing and steady decline in COVID-19 deaths and cases, most state governments are vowing to maintain their lockdowns and mask mandates, some forever or until a vaccine is found.

Numerous high-ranking public authorities throughout the United States have pledged to continue enforcing COVID-19 restrictions — including social distancing rules and mask mandates — even as cases of and deaths attributed to the virus continue a steady two-month decline throughout the country.

Those officials have signaled that the restrictions will not be lifted unless and until an effective vaccine is developed, approved, distributed throughout the country and utilized by enough of the population to create functional herd immunity.

The graph to the right, compiled from this source, shows clearly that the epidemic is fading, and even at its peak never came even close to the terrifying predictions, all now proven to be wrong, of a lot of health officials and junk modeling scientists.

In fact, the numbers continue to show that coronavirus is really nothing more than a bad flu. Like the flu, it is relatively harmless to the young and healthy, who either will show no symptoms from it at all, or might get sick for a week or so and then recover completely. And like the flu, it is only really dangerous to the old and sick, who already have serious health problems which make them vulnerable to any new illness.

Note too that the average age at death from COVID-19 is about 78 years old, which is also identical to the average age expectancy of Americans. In other words, the disease did little to change the number of deaths at all. Even if there were excess deaths this year, they were not much more than we’ve had in previous bad flu seasons, and those additional deaths had no effect on the general population.

For such a disease, you do what we have done for centuries, you protect the weak, and let everyone else live their lives normally. We did not do this this time, and are now suffering from it.

Worse, too many people seem unwilling to accept the reality that the epidemic is ending. Instead, they get outraged by anyone who even suggests such a thing. They have fallen in love with their fear, and want to embrace it, forcing masks and restrictions on everyone forever, just so that they have a false sense of safety.

Unfortunately too many of our fascist governors and health bureaucrats have decided to take full advantage of that panicky fear and use it to gain more power over everyone. As it is said, power corrupts, and absolute power corrupts absolutely. For the past six months we have seen a perfect demonstration of this.

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.

Martian channels within Martian channels

Channels within channels on Mars
Click for full image.

Whatever caused the meandering canyons on Mars, whether glaciers or liquid water, it was a process that was long-lived and multi-staged, as indicated by today’s cool image to the right, rotated, cropped, and reduced to post here. This photo, taken on June 28, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), shows a large canyon cutting downward from a high ridgeline to the north. As that canyon begins to flow out out of the mountains and into the plains to the south, a secondary inner channel appears, meandering down the center of the larger canyon.

This canyon is located at 35 degrees south latitude, in the mid-latitude region where scientists have found evidence of a lot of glaciers. In fact, there are some hints of eroded glacial material in the small channels to the west of this main canyon. Also, there appear to be patches of corroding glacial ice on the south-facing slopes of the east and west hills that define the main channel. In the canyon itself however there appear to be few if any glacial-type features.

The overview map below gives the location context.

A UV aurora found on Comet 67P/C-G

9:06 am

Using data from Europe’s now completed Rosetta mission to Comet 67P/C-G, scientists have detected evidence that the comet’s interaction with the Sun’s solar wind creates an aurora above the comet in ultra-violet wavelengths.

The data indicate 67P/C-G’s emissions are actually auroral in nature. Electrons streaming out in the solar wind – the stream of charged particles flowing out from the Sun – interact with the gas in the comet’s coma, breaking apart water and other molecules. The resulting atoms give off a distinctive far-ultraviolet light. Invisible to the naked eye, far-ultraviolet has the shortest wavelengths of radiation in the ultraviolet spectrum.

Labeling this phenomenon as an aurora is a bit of hype, as nothing is visible. However, the discovery does tell scientists how this comet’s coma, produced when the comet heats up in its approach to the Sun, interacts with the solar wind, and this in turn can teach them more about that wind, as well as other comets.

Rocks from Vesta on Bennu?

8:51 am

Scientists reviewing data of Bennu from OSIRIS-REx have found six very bright boulders that have a make-up similar to that found on Vesta, which suggests they initially came from that asteroid.

The unusual boulders on Bennu first caught the team’s eye in images from the OSIRIS-REx Camera Suite. They appeared extremely bright, with some almost ten times brighter than their surroundings. They analyzed the light from the boulders using the OSIRIS-REx Visible and Infrared Spectrometer instrument to get clues to their composition. … The signature from the boulders was characteristic of the mineral pyroxene, similar to what is seen on Vesta and the vestoids, smaller asteroids that are fragments blasted from Vesta when it sustained significant asteroid impacts.

Of course it’s possible that the boulders actually formed on Bennu’s parent asteroid, but the team thinks this is unlikely based on how pyroxene typically forms. The mineral typically forms when rocky material melts at high-temperature. However, most of Bennu is composed of rocks containing water-bearing minerals, so it (and its parent) couldn’t have experienced very high temperatures. Next, the team considered localized heating, perhaps from an impact. An impact needed to melt enough material to create large pyroxene boulders would be so significant that it would have destroyed Bennu’s parent-body. So, the team ruled out these scenarios, and instead considered other pyroxene-rich asteroids that might have implanted this material to Bennu or its parent.

The make-up of Vesta matches. While these rocks might have been flung from Vesta during an impact there, eventually to settle on the surface of Bennu, Vesta is not the only possibility. We do not have a good census of the asteroids in the solar system. Others whose make-up is not yet determined could be a source, as well as an asteroid that no longer exists, destroyed by a collision long ago.

Regardless, these rocks confirm that in the process of formation in the early days of the solar system, asteroids of all types exchanged material.

First manned Artemis Moon mission might not go to south pole

3:59 pm

In order to meet the Trump administration’s 2024 deadline for the first Artemis manned lunar landing, NASA is now considering sending that first mission to an equatorial target, rather than the Moon’s south pole.

The Artemis program landing site issue came up at two separate events with agency leaders this week, beginning with NASA Administrator Jim Bridenstine’s comments to open a digital meeting held by a NASA advisory group called the Lunar Exploration Analysis Group, on Monday (Sept. 14).

“For the first mission, Artemis 3, our objective is to get to the south pole,” Bridenstine said. “But … it would not surprise me if, for example, if we made a determination that the south pole might be out of reach for Artemis 3, which I’m not saying it is or isn’t,” interest in the Apollo sites may win out.

The engineering to get to the polar regions is more challenging, so rather than delay that first mission they are considering simplifying it instead.

The fact remains that Congress has still not funded any Artemis missions beyond the first unmanned and first manned flights, neither of which will land on the Moon. Whether that money will ever be forthcoming really depends entirely on the November election, as well as the success or failure of the upcoming full-up static fire engine test of the SLS first stage.

Mt Wilson Observatory survives wildfire

3:47 pm

Firefighters in the past few days managed to stop the wildfire that had come within 500 feet of the historic Wilson Observatory, saving it from destruction.

There were some tense moments on the afternoon of Tuesday, September 15th, as the Bobcat Fire approached within 500 feet of the observatory complex. The battle was on after a 500–1,000 acre spot fire jumped Highway 2 in the Angeles National Forest. Fire crews rallied, cutting fire lines while aircraft flew fire suppression sorties overhead to defend the observatory. By Tuesday night, the worst had passed, though officials stressed that the effort was far from over.

The article also notes the tragic destruction of an amateur telescope observatory in another California wildfire. It will take $30,000 to local club to rebuild.
