MASCOT ends its mission on Ryugu, as planned

10:52 pm

Hayabusa-2’s mini-lander MASCOT has ended its mission on Ryugu after seventeen hours, slightly longer than the planned sixteen hours.

The lander made one hop, and successfully transmitted all its data back to Hayabusa-2, which still has one more mini-lander on board that will be sent to Ryugu’s surface, probably after Hayabusa-2 makes its own landing.

Meanwhile, the two Minerva-2 bouncers continue to operate on Ryugu.

Commercial crew test flights delayed again

10:43 pm

NASA today released an updated schedule for the Dragon and Starliner test flights, indicating the first Dragon flight has been pushed to January 2019.

  • SpaceX Demo-1 uncrewed flight test: January 2019 (delayed from November 2018)
  • Boeing uncrewed Orbital Flight Test: March 2019 (delayed from late 2018/early 2019)
  • SpaceX Demo-2 crewed flight test: June 2019 (delayed from April 2019)
  • Boeing Crew Flight Test: August 2019 (nominally still in mid-2019 as earlier stated)

It appears from the article that SpaceX was prepared to fly its first flight in December, meaning only a one month delay, but scheduling conflicts at ISS forced them to push it to January.

With the Boeing flights, the scheduling has less to do with delays and more do to do with setting more precise launch dates.

Democratic doxxer threatened to also release the health data of the children of Republicans

1:45 pm

They’re coming for you next: The Democratic congressional aide who has been arrested for releasing private information of at least three Republican elected officials also threatened to release the health information and social security numbers of their children if anyone turned him in.

Jackson Cosko, who recently worked for Rep. Sheila Jackson Lee, D-Texas, was arrested for allegedly posting the personal information (or “doxxing”) of a number of senators including Lindsey Graham, R-S.C., Mike Lee, R-Utah, and Orrin Hatch, R-Utah on Wikipedia — with information such as their home addresses and phone numbers. Graham, Lee and Hatch’s information was published on Thursday.

According to a sworn statement by Capitol Police Captain Jason Bell, a witness Tuesday saw Cosko at a computer in a senator’s office, where he used to work, a day after two other unnamed senators’ information had been put on Wikipedia. Cosko worked for other Democratic senators including Sen. Dianne Feinstein, D-Calif., Sen. Maggie Hassan, D-N.H., and former Sen. Barbara Boxer, D-Calif. While earlier reports identified Cosko as an intern for Jackson Lee, his lawyer said that he was working as a fellow in her office, paid by an outside institution.

Sources familiar with the case tell Fox News Cosko was in Sen. Hassan’s office, where he was caught using a login he was not authorized to use. Cosko earlier was let go by Senator Hassan’s office. A spokesman for Hassan says she “strongly denounces the alleged actions.”

According to Bell’s statement, Cosko is alleged to have been confronted by the staffer and then walked out. Hours later the witness received an email from “livefreeorpwn@gmail.com” saying: “If you tell anyone I will leak it all. Emails signal conversations gmails. Senators children’s health information and socials.”

While his actions have been disavowed by the Democratic lawmakers for whom he worked, his actions reveal once again the fascist and hateful culture that presently permeates the entire left. They are willing to do you real harm, and if that doesn’t make you shut up and stop opposing them, they will go after your children.

Don’t believe me? You still think this is only a rare exception? Then read this letter from the wife of Senator Rand Paul (R-Kentucky):

Paul wrote Wednesday that she and her family had “experienced violence and threats of violence at a horrifying level” over the past 18 months. “I now keep a loaded gun by my bed,” she said. “Our security systems have had to be expanded. I have never felt this way in my life.”

For decades the Democrats have allowed this kind of behavior to go unpunished. It is now getting out of their control. Bad things are coming. If you don’t tow the leftist line, get ready. Be prepared. You will need to defend not only yourself, but all your loved ones.

A vent on Mars?

1:29 pm

A vent on Mars?

Cool image time! In their exploration of the surface of Mars using Mars Reconnaissance Orbiter (MRO), scientists often image geological features that strongly resemble Earth features. Sometimes, if real, the resemblances are significant, as they indicate important geological activity on Mars that can tell us a lot about the conditions and environment there.

The image on the right, cropped and reduced in resolution to post here, is a good example of this. It was taken by MRO on June 14, 2018, just before the global dust storm obscured the planet’s middle latitudes for most of the summer, and was part of the monthly release of new images from the spacecraft. (If you click on the image you can see the full resolution picture.) The release website, which includes no caption, describes this feature as an “apparent vent,” a determination that certainly seems reasonable. The shadowed dark features suggest an abrupt oblong pit near the edge of a cliff, formed in the center of a collapsed sink. The tear-drop shape of the collapse sink and surrounding darkened areas also suggests that something is venting from it and then blowing away to the east and south, forming the darker stained ground. Some of the dark features to the southeast might also be smaller vents, releasing their own materials into the atmosphere.

The location also reinforces this suggestion, located on the southeast lava slopes of one of Mars’ larger volcanoes, Elysium Mons. This is also a region, dubbed Athabasca Valles, that some planetary scientists believe is one of the youngest lava flows on Mars.

Finally, it appears that the pit here has darkened considerably recently. MRO has taken images of this pit twice previously, in 2008 and 2010, and in both images the pit is much lighter in color, with its sandy dune-covered floor much easier to see. In the new image the floor is now very dark. This might be caused by shadows and the angle of the Sun, but I don’t believe so. It is also clear when comparing all three images that the surrounding area, including the flow to the southeast, has also darkened with time.

All this data suggests that the pit is venting something into the air, and it is settling on the ground to the southeast, blown there by the prevailing winds. Nor is this pit the only such feature in this region. Other images by MRO show a lot of similar dark splotches.

The problem is that this feature is not on Earth but on Mars. Determining what is being vented, and why, is therefore made more difficult. Based on Earth data you would assume this is some form of volcanic vent, releasing gases from below the surface. On Mars that assumption might not hold. We might instead be seeing the venting of any number of possible materials, such as underground water-ice, carrying with it other underground materials and thus darkening the surface.

We also can’t assume that the venting is occurring because of volcanic processes. On Mars the evidence so far gathered suggests that active volcanic activity ceased a very long time ago, even for this very young lava region. The venting is likely caused by something else, a fact that in itself is probably the most significant take-away from these images.

Something appears to be causing an active vent on the surface of Mars. Finding out the root cause of that venting is probably one of the more interesting questions facing researchers who study the Martian surface.

SpaceX turned down government money to build Falcon Heavy

10:17 am

Capitalism in space: In a presentation yesterday in Europe, one of SpaceX’s executives, Hans Koenigsmann, made it clear that SpaceX paid entirely for the development of Falcon Heavy, and in fact turned down an offer of government funding.

According to the SpaceX executive, the company was actually approached by “the government”, with the unknown agency or agencies stating – in Hans’ words – that they wanted to be a part of the rocket’s development. According to Hans, SpaceX responded in an extremely unorthodox fashion: “we said, ‘Nope! We just wanna build it, you can buy it when it’s ready and we’ll charge you for the service.’” He noted in the next sentence that funding was the primary lever on the table: “It’s a great position to do this, you gotta find the money, you gotta know people that have money and are willing to invest in your company, and [SpaceX has] been lucky enough to know some of those people.”

In other words, when given an opportunity to either rely on government funding or some other source of capital for a given R&D project, SpaceX – or at least Hans Koenigsmann, VP of Reliability – would apparently recommend the latter option in almost all cases. Again, without being prompted, he elaborated on his feelings about funding sources, culminating in a statement that is simply profound coming from an executive in the aerospace industry. The following quote is unabridged and straight from Hans himself:

“You need to [try to not] get money from the government, otherwise the government will tell you what to build and how to build it… they will tell you how to build this and that’s just not always – I mean for some things it’s the best to do, but in others it’s actually not.”

In other words, don’t let the government run your business. Use the government as an eventual customer, but build your product in a way that will not make them your only customer.

You can watch his entire presentation in the embedded video below the fold. Koenigsmann also noted that this Sunday’s first attempt to land a first stage at Vandenberg will likely produce a spectacular show for anyone who watches.

How one region’s space industry represents the world

9:20 am

bumper sticker

On October 2 I attended for the first time a monthly meeting of the Arizona Space Business Roundtable, an informal gathering put together by Stephen Fleming of the University of Arizona’s Strategic Business Initiatives and designed to allow the various space businesses of southern Arizona to network together as well as highlight what they are accomplishing to themselves and to others.

This particular meeting involved the presentation to the business community of a study that looked into the potential growth possibilities for space within the Tucson region. The study had been financed by the University of Arizona, several local venture capital companies, and the local county government, and had found that southern Arizona’s most likely source of space business in the near future would revolve around the need to track and monitor the large number of satellites expected to be launched in the coming decades. This would also involve substantial military work, as well as related space junk clean-up duties. The study also found that the southern Arizona space industry is well suited to provide much of the growing support services that future space missions, both governmental and private, will need. You can read more about the study’s results and the meeting at this Arizona Star article.

What struck me most about this gathering and the space industry of southern Arizona, however, is how much it resembles the regional space industries in numerous other places throughout the United States and the world. In fact, during a panel discussion after the presentation Fleming specifically asked the panelists — made up of several local companies (Vector, Worldview, Paragon) and two venture capital companies — what other regions in the U.S. posed the most competitive threat to southern Arizona. The panelists quickly listed Denver-Boulder, Silicon Valley in California, Huntsville in Alabama, the Space Coast in Florida, and New Mexico. They also made it clear that this list was not complete.

All of these regions are presently prospering and, more important, growing. All see a bright future in space, and all are aggressively competing to grab as large a market share in this future as they can. Even more significant, there appears to be more than enough business to go around. With numerous new countries pushing their own space efforts (China, India, UAE, Great Britain, Luxembourg, to name only a few), and both the American government as well as private companies attempting their own missions to the Moon and beyond, the possibilities appear endless. A lot of government money and investment capital is presently being poured into space, and numerous regions throughout the world are reaching for that money and the future profits it will bring.

And all of these regions are stock full of numerous independent and private companies and individuals, all pushing their own ideas about how space should be explored and conquered.

There are many aspects of the present charge to explore and settle the solar system that I do not like and believe will actually hamper and slow that exploration and settlement. Nonetheless, this charge is happening worldwide, and with amazing and increasing vigor. Even the worst proposals, such as NASA’s Gateway project, are going to eventually lead to new space technologies and capabilities that will sooner or later make it possible for the human race to routinely travel throughout the solar system.

It appears that the next two decades will lay the groundwork for the next few centuries of space exploration. And much of that groundwork will take place out of sight of the general public, with small companies located in regions like these. As with all great endeavors, the structure is that of a pyramid. At the top is the leader (such as SpaceX) that everyone watches and admires. Below it however is a vast subculture that provides the foundation for that leadership, even as it pushes upward to compete against it.

These are exciting times. I suggest if you love space you climb on the rocket now, before it picks up so much speed it will be beyond your reach.

NASA study says deep space will cause cancer and destroy stomachs

8:35 am

We’re all gonna die! A NASA study on rats using simulated space radiation suggests that long duration space missions beyond Earth orbit will cause cancer as well as significant harm to human intestines.

The study, published by cancer researchers at Georgetown University Medical Center, used mice to test exposure to heavy ion radiation, which mimics the galactic cosmic radiation found in deep space. If that sounds complicated, essentially researchers compared “space” radiation to X-ray radiation and found its effects to be much more dangerous.

After long exposures to a low dose of galactic radiation, mice had permanent damage to their gastrointestinal tracts and could no longer absorb nutrients in food. The mice also developed cancerous growths in their intestines — raising concerns that astronauts who venture far into space would face the same deadly health issues. “While short trips, like the times astronauts traveled to the moon, may not expose them to this level of damage, the real concern is lasting injury from a long trip,” said Kamal Datta, head of Georgetown’s NASA Specialized Center of Research, in a press release.

More here.

Must I point out the uncertainties and weaknesses of this study? They did the test on rats. They simulated the radiation. And it appears they simulated the radiation dosages assuming the spacecraft would have little or no shielding, an absurd approach.

Space is dangerous, but there is no reason to exaggerate the dangers wildly, unless you wish to generate fake reasons for additional funding, as NASA is prone to do.

Curiosity to switch computers in effort to restore operations

10:44 pm

The Curiosity engineering team have decided to switch on-board computers in effort to figure out why the rover has been unable to store and send any data since September 15.

After reviewing several options, JPL engineers recommended that the rover switch from Side B to Side A, the computer the rover used initially after landing.

The rover continues to send limited engineering data stored in short-term memory when it connects to a relay orbiter. It is otherwise healthy and receiving commands. But whatever is preventing Curiosity from storing science data in long-term memory is also preventing the storage of the rover’s event records, a journal of all its actions that engineers need in order to make a diagnosis. The computer swap will allow data and event records to be stored on the Side-A computer.

Side A experienced hardware and software issues over five years ago on sol 200 of the mission, leaving the rover uncommandable and running down its battery. At that time, the team successfully switched to Side B. Engineers have since diagnosed and quarantined the part of Side A’s memory that was affected so that computer is again available to support the mission. [emphasis mine]

As indicated by the highlighted paragraph, the switch does carry some risk. Though they say they have isolated the problems with the A computer, they might be surprised when they turn it on.

Meanwhile, silence continues from Opportunity. After fourteen years of almost continuous rover operations on Mars, the United States have been roverless now for more than two weeks.

The first exomoon found?

11:29 am

Worlds without end: Scientists using data from the Hubble Space Telescope and Kepler have detected evidence that suggests the discovery of the first moon outside our solar system.

The data indicate an exomoon the size of Neptune, in a stellar system 8000 light-years from Earth. The new results are presented in the journal Science Advances.

…In 2017 NASA’s Kepler Space Telescope detected hints of an exomoon orbiting the planet Kepler-1625b. Now, two scientists from Columbia University in New York (USA) have used the incomparable capabilities of the NASA/ESA Hubble Space Telescope to study the star Kepler-1625, 8000 light-years away, and its planet in more detail. The new observations made with Hubble show compelling evidence for a large exomoon orbiting the only known planet of Kepler-1625. If confirmed, this would be the first discovery of a moon outside our Solar System.

The candidate moon, with the designation Kepler-1625b-i, is unusual because of its large size; it is comparable in diameter to the planet Neptune. Such gargantuan moons are unknown in our own Solar System. “This may yield new insights into the development of planetary systems and may cause astronomers to revisit theories of how moons form,” Alex Teachey, a graduate student who led the study, explained excitedly.

Like its moon, Kepler-1625b is also bigger than its counterparts in the Solar System. The exoplanet is a gas giant, several times more massive than Jupiter. It orbits its parent star at a distance similar to the distance between the Sun and Earth, which puts it — and its candidate moon — at the inner edge of the habitable zone of the star system.

The alien nature of this solar system should not surprise us. If anything, it is only a hint at the wild and exotic solar systems we have yet to discover.

NASA signs agreement to work with SpaceIL’s privately built lunar rover

11:21 am

Capitalism in space: NASA, the Israeli space agency, and the private Israeli space company SpaceIL have signed a cooperative agreement to work together when SpaceIL’s privately built lunar rover is launched to the Moon in December.

NASA will contribute a laser retroreflector array to aid with ground tracking and Deep Space Network support to aid in mission communication. ISA and SpaceIL will share data with NASA from the SpaceIL lunar magnetometer installed aboard the spacecraft. The instrument, which was developed in collaboration with the Weizmann Institute of Science, will measure the magnetic field on and above the landing site. The data will be made publicly available through NASA’s Planetary Data System. In addition, NASA’s Lunar Reconnaissance Orbiter will attempt to take scientific measurements of the SpaceIL lander as it lands on the Moon.

This agreement is the first step in the transition from having the government build planetary probes to it becoming a customer, buying these probes from private companies that build them for profit.

More fake papers accepted by sociology/gender/racism journals

10:59 am

In what has become almost a regular event, several honest academics (who call by the way identify themselves as “leftwing”) have once again successfully gotten published seven bogus papers in journals centered on gender, feminist, race, and ethnic studies.

Once they had a grasp on what was already being published, they quickly wrote 20 bogus papers. Seven of those were accepted for publication by various journals and several others were pending rewrites and probably would have been accepted if the authors hadn’t been forced to call off the experiment early. For comparison purposes, seven papers is the average number you would need to publish over seven years in order to secure tenure at most universities. The authors estimate at least 10 of the 20 would have been accepted given more time. And they could have kept churning these out and had one or two new papers accepted for publication every month, for as long as they wanted to continue.

They key point here is that the papers themselves were written not as an attempt to expand knowledge but as pure sophistry. Each one started with an absurd premise and then used the contours of social justice thought, what the authors call “grievance studies,” to make the premise seem plausible.

It is worth reading their full report. To show how corrupt these fields have become, one of those accepted papers simply took a chapter of Hitler’s Mein Kampf and reshaped it slightly using feminist jargon. As the project’s authors found. the point of these publications has nothing to do with knowledge,

This is the primary point of the project: What we just described is not knowledge production; it’s sophistry. That is, it’s a forgery of knowledge that should not be mistaken for the real thing. The biggest difference between us and the scholarship we are studying by emulation is that we know we made things up. [emphasis in original]

Below the fold is a short video the three scholars produced to explain their work, what it accomplished, and their own conclusions, which strongly condemn the entire field of ethnic, race, and gender studies.

The real problem however is not what these scholars learned and demonstrated. That these fields are corrupt and infused with leftist political ideology that makes all worthwhile research impossible has been proven for decades. In 1996 physicist Alan Sokol did exactly the same thing, getting a top sociology journal to publish a fake paper purposely filled with the obtuse leftist jargon that these journals prize.

The real problem is that nothing changes. These journals continue to publish this crap and the departments and fake professors who produce it continue to be funded. In fact, since Sokal’s hoax in 1996 their funding and power has grown, not shrunk, despite repeated similar stories in the past two decades demonstrating their willingness to publish fake papers, as long as those papers advocate political leftist garbage that works to destroy the search for truth that is the hallmark of western civilization.

The journals that accepted the seven papers above should all be shut down, today. The schools that fund the departments that publish in those journals should be closed, today. The professors who teach in those departments should be fired, today. None of them contribute anything worthwhile to our society or to academic scholarship, and in fact they are fueling the racial hatred and intolerance that is now pervading American intellectual society.

Unfortunately, I have no faith that any of that will happen. Instead, I expect their corrupt bigoted leftist effort to continue to grow, permeating more aspects of modern intellectual life, with the resulting hate they engender causing a growth in violence and oppression.

A new Moon Race contest established

9:51 am

Led by Airbus, a number of private space companies and government agencies have established a new space contest dubbed “The Moon Race.”

The Moon Race competition is a global initiative founded by Airbus and international partners, aiming to boost the movement around Moon exploration and enable the demonstration of key technologies required for its sustainable exploration.

The Moon Race targets startups and SME’s worldwide and has the ambition to bring the winning teams to the lunar surface and provide solutions for the uprising lunar economy.

The competition is managed by “The Moon Race NPO gGmbH”, a not-for-profit organization based in Germany, whose goals are to manage The Moon Race competition and bring together the international space – and non-space – communities into one coordinated international initiative.

The partners listed so far are Airbus, Blue Origin, Vinci (an Italian space company), the European Space Agency, and Mexico’s space agency. Though their webpage is somewhat vague, it appears they are looking for new companies to join a program to compete for monetary prizes handed out year by year though 2023.

ISS’s international partners express interest in extending station’s life

9:42 am

While NASA has been considering the end of ISS, this week its international partners all expressed interest this week in extending its life beyond 2024.

During an Oct. 1 press conference at the 69th International Astronautical Congress (IAC) here, representatives of three ISS partner agencies said they were open to extending the station’s operations to 2028 or 2030 in order to maximize the investment they’ve made in the facility as a platform for research and preparation for exploration activities beyond Earth orbit.

Jan Woerner, director general of the European Space Agency, said the issue could come up at the next triennial meeting of the ministers of ESA’s member nations, scheduled for late 2019. “At the ministerial meeting next year, the ministerial council, I will propose to go on with ISS as well as the lunar Gateway,” he said. “I believe that we will go on.”

At a separate briefing Oct. 2, Woerner emphasized the use of the station as a research platform and encouraged greater commercial activities there. “I believe we should use the ISS as long as feasible,” he said. “I always thought 2024 was the end, but now I learned it is 2028, and yesterday I learned it’s 2030. So, I will try to convince the ESA member states that ESA should be a partner in the future.” However, he noted that ESA could defer the decision on a post-2024 ISS extension until its following ministerial meeting in 2022.

Hiroshi Yamakawa, president of the Japanese space agency JAXA, also emphasized the importance of making the most of the station. “I’d like to make the most of the present ISS,” he said. “We have to maximize the output of the ISS. Whenever the deadline comes to the ISS, we would like to participate in the ISS and maximize output.” He added, though, that there was not a pressing need for Japan to decide on an ISS extension. “JAXA is requesting budgets annually, so I think in that sense JAXA is quite flexible.”

Dmitry Loskutov, head of international relations at the Russian state space corporation Roscosmos, said Russia already expected an extension. “We anticipate the continued functioning until 2028 or 2030,” he said.

While I can see many benefits for extending ISS, leaving it as a wholly government-run operation will reduce its effectiveness while increasing its cost. I also suspect all these agencies are lobbying for funding. If they can get money for both ISS and Gateway, it will increase their footprint in space significantly.

Astronomers discover very distant object orbiting the Sun

9:32 am

Astronomers have discovered a very distant object in a solar orbit ranging from 6 billion to 213 billion miles from the Sun.

Designated 2015 TG387 and nicknamed “The Goblin” by its discoverers, this object resides in the inner Oort Cloud, a region beyond the Kuiper Belt that until now harbored only two other known bodies: the dwarf planet Sedna and the less well-known 2012 VP113.

The scientists estimate its size to be about 200 miles in diameter. Based on the existence of the three known objects in this region of space, the scientists estimate there could be as many as 2 million objects there bigger than 25 miles in diameter. There is a lot of uncertainty in that number.

Roscosmos cuts price for Soyuz rocket launch

9:24 am

Russia has announced it is now charging only $48.5 million for a Soyuz-2/Freget launch, a significant reduction in its previous launch prices.

The basic price to launch Russia’s Soyuz-2.1 carrier rocket with the Fregat booster will stand at about $48.5 million, the Russian launch service provider, Glavkosmos Launch Services, has said. “On the first day of the International Astronautical Congress in Bremen, our team announced the basic price to launch a Soyuz-2.1 carrier rocket with the Fregat booster. It comes to $48.5 million,” the company said in a statement, posted on Facebook.

The launch of the Soyuz-2.1 without the Fregat booster would cost about $35 million. “Therefore, the delivery of 1 kg of cargo by a Soyuz-2 rocket will cost $20,000-30,000… which is below the average market price,” the statement reads.

This makes the rocket competitive with SpaceX’s Falcon 9, though (I think) it cannot place as much payload into orbit. This price drop also proves that SpaceX’s low prices are not merely “dumping,” as claimed by Roscosmos head Dmitry Rogozin. The Russians have now shown that they can launch at this price, just as SpaceX has. It merely took the competition from SpaceX to force them to cut costs for their customers.

Hayabusa-2’s third mini-lander successfully lands on Ryugu

8:55 am

MASCOT image of Ryugu surface

Update: The image at right, reduced to post here, was taken by MASCOT during its descent. You can see the spacecraft’s shadow in the upper right. If you click on the image you can see the full resolution version.

Original post: The German/French-build mini-lander MASCOT has been successfully deployed by Hayabusa-2 and has successfully landed on the asteroid Ryugu.

MASCOT came to rest on the surface approximately 20 minutes after the separation. Now, the team is analysing the data that MASCOT is sending to Earth to understand the events occurring on the asteroid Ryugu. The lander should now be on the asteroid’s surface, in the correct position thanks to its swing arm, and have started to conduct measurements independently. There are four instruments on board: a DLR camera and radiometer, an infrared spectrometer from the Institut d’Astrophysique Spatiale and a magnetometer from the TU Braunschweig. Once MASCOT has performed all planned measurements, it is expected to hop to another measuring location. This is the first time that scientists will receive data from different locations on an asteroid.

The spacecraft took 20 pictures during its descent, which were beamed to Hayabusa-2 where they are presently stored.

Celebrate Earthrise Day!

1:59 pm

In only a little less than three months we will be celebrating the fiftieth anniversary of the December 1968 flight of Apollo 8 — first manned mission to another world. During that mission three humans spent 20 hours in orbit around the Moon, during which they read the first twelve verses of the Old Testament on Christmas Eve and became the first humans to witness an Earthrise and to photograph it.

To celebrate that achievement, a new website has been created, dubbed Celebrate Earthrise Day.

The website provides some great background material. You can listen to the astronaut’s Christmas telecast as well as see a recreation of the moment when the astronauts saw that Earthrise and Bill Anders took his famous color photo. The site also includes many photos from before, during, and after the mission, with many pictures coming from the personal family pictures of the astronauts. There is also audio of an 1988 Bill Anders’ interview, as well as a video of a fascinating presentation made by Bill and Valerie Anders, describing their life journey leading up to Apollo 8 and afterward.

Finally, and I think of most interest to my readers here, the site includes the audio of my introduction from the new audio edition of my book, Genesis: the Story of Apollo 8.

The site also includes the audio of one of the best radio interviews I have ever done, broadcast in 1998, on the subject of Apollo 8, our American culture, and the importance of each person choosing their path in life wisely. You can find that audio at the bottom of this webpage.

Check it all out. I think you will find it worth your while.

More intergalactic stars discovered

9:22 am

Worlds without end: Using the data from Gaia’s second data release astronomers have identified twenty stars that are moving too fast to be permanent members of the Milky Way galaxy.

More significantly, most appeared to be approaching the galaxy, not flying away from it, suggesting they are visitors from other galaxies.

It is possible that these intergalactic interlopers come from the Large Magellanic Cloud, a relatively small galaxy orbiting the Milky Way, or they may originate from a galaxy even further afield. If that is the case, they carry the imprint of their site of origin, and studying them at much closer distances than their parent galaxy could provide unprecedented information on the nature of stars in another galaxy – similar in a way to studying Martian material brought to our planet by meteorites.

…An alternative explanation is that the newly identified sprinting stars could be native to our Galaxy’s halo, accelerated and pushed inwards through interactions with one of the dwarf galaxies that fell towards the Milky Way during its build-up history. Additional information about the age and composition of the stars could help the astronomers clarify their origin.

At least two more data releases shall come from Gaia, launched by Europe to precisely track the location and motions of a billion stars. So far, they have complete 3D velocity information for about seven million stars. After these additional data releases they expect to have complete 3D velocity information for 150 million stars, and should identify a lot more intergalactic stars at that time.

Deployment operations for Hayabusa-2’s MASCOT lander have begun

9:07 am

Engineers have begun the deployment sequence for Hayabusa-2’s MASCOT lander, with deployment planned for tomorrow.

Right now Hayabusa-2 is slowly moving closer to Ryugu, with live images appearing about once every half hour. More information about MASCOT can be found here. The lander can also hop like the MINERVA bouncers, but it can only do it once. Its battery life is about sixteen hours, so once it is deployed it will only operate on the surface for a short while.

Both the MINERVA and MASCOT mini-landers are mostly engineering tests for using small cubesat-sized spacecraft as probes. So far the MINERVA bouncers have been an unqualified success. Hopefully MASCOT will be as successfully.

Breakthrough Listen adds southern hemisphere telescope to extraterrestrial listening campaign

8:51 am

Breakthrough Listen has added the MeerKAT telescope in South Africa to its extraterrestrial listening campaign, thereby expanding the campaign to cover almost the entire sky.

Breakthrough Listen’s MeerKAT survey will examine a million individual stars – 1,000 times the number of targets in any previous search – in the quietest part of the radio spectrum, monitoring for signs of extraterrestrial technology. With the addition of MeerKAT’s observations to its existing surveys, Listen will operate 24 hours a day, seven days a week, in parallel with other surveys. “Collaborating with MeerKAT will significantly enhance the capabilities of Breakthrough Listen”, said Yuri Milner, founder of the Breakthrough Initiatives. “This is now a truly global project.”

Built and operated by the South African Radio Astronomy Observatory (SARAO), and inaugurated in July 2018, MeerKAT is a powerful array of 64 radio antennas in the remote Karoo Desert of South Africa. By partnering with SARAO, Breakthrough Listen gains access to one of the world’s premier observing facilities at radio wavelengths. Signals from the 64 dishes (each 13.5 meters in diameter) are combined electronically to yield an impressive combination of sensitivity, resolution and field of view on the sky. MeerKAT also serves as a precursor for the Square Kilometre Array, which will expand and enhance the current facility in the coming decades, eventually spanning a million square meters across South Africa and Australia to create by far the world’s largest radio telescope.

They have also widened their approach. They are not simply looking for intelligent radio communications, they are looking for any signs of technology.

“Kill Kavanaugh” now tops Twitter feeds

9:21 am

They’re coming for you next: “Kill Kavanaugh” now tops Twitter search feeds, requiring only the typing of a “k” to get it near the top of any search, with “ki” placing at the very top of the search list.

Although many current tweets on the hashtag are critical of both the hashtag and Twitter’s double standards, earlier tweets use the hashtag unironically and uncritically. Several of these tweets have not been removed by Twitter, and the accounts that tweeted them do not appear to have been punished by Twitter in any way, despite the fact that some users say they have reported them.

It can be argued that some — but not all — of these tweets are metaphorical, calling for the nomination to be “killed” rather than the person, in the same way that a piece of legislation might be metaphorically “killed.” But refusing to take action against those tweets would still be an example of Twitter’s double standards: the platform has in the past permanently banned free speech maximalist users when they employed similar metaphors, using the least charitable interpretation of their remarks. This is the website that has silenced James Woods for tweeting a meme about soy boys that Jack Dorsey and his San Francisco menagerie argue could “impact an election.”

Twitter in general is a sewer of vicious hate and childish emotions, but that its management is willing to tolerate this kind of behavior from the left indicates they really support it.

The left, and the Democrats, are out for full and unopposed power, and they are willing to destroy anyone they perceive as getting in their way. Unfortunately, they have quislings like Senator Jeff Flake (R-Arizona) helping them. The man would have built the gas chambers for the NAZIS if they had asked him.

Occator Crater on Ceres

9:14 am

Occator Crater

Cool image time! As Dawn’s long and successful mission to the asteroids Vesta and Ceres winds down, the spacecraft is taking a slew of spectacular close-up images of Ceres. The image on the right, cropped slightly to post here, is an oblique view of Occator Crater, home to the double bright spots that scientists now believe are caused by the upward seepage of a water-based brine from the interior.

The image was taken August 14, 2018 from a distance of 1149 miles. It clearly shows how the bright spots are depressions, not raised features. Additional images released this week of the floor of the crater capture a complex fracture network (seen here and here) with some fractures apparently quite deep.

All this suggests that the surface crust of Ceres is not very structurally strong, allowing a churning process that plows material up and down. The data also suggests that even on a small planetary body like Ceres the geological processes are going to be complex and often on-going, depending on material, energy, and the size of the body.

Russia and China sign agreement for future space cooperation

8:56 am

The new colonial movement: Russia and China last week signed an agreement to establish a greater cooperation in future space projects.

“The session ended with the signing of a protocol in which the two parties agreed to take further steps to seek rapprochement in implementing joint projects for the manufacture of space vehicles and rocket engines, exploring the Moon and deep space, remote sensing of the Earth, satellite navigation, creating a base of electronics components for the space industry, and low orbit mobile communication systems and space debris monitoring,” the report runs.

This is a direct negotiating threat from Russia to the U.S., telling us that they might switch teams from NASA to China if they don’t get what they want in the Gateway partnership. And since NASA really doesn’t have the ability to build much itself (more on this later today), if they make this switch it could very well kill Gateway, all by itself.

Because of this, expect NASA management (part of the DC culture) to backstab the U.S. in any negotiations with Russia on Gateway. Rather than defend U.S. interests, they will instead be focused on guaranteeing Russia participation, even if the deal might cripple the burgeoning private American space industry.
