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 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.

Another Obamacare co-op shuts down
Finding out what’s in it: With Maryland’s Obamacare co-op closing on December 8, 20 of the original 24 Obamacare co-ops have gone out of business.
With the near-collapse of Maryland’s co-op — called Evergreen Health — at least 989,000 individuals nationwide have lost their health insurance coverage when the nonprofit co-ops stopped selling insurance to customers, according to TheDCNF’s tally. The losses cost taxpayers at least $2.2 billion in upfront federal loans awarded by the Obama administration to 24 nonprofit co-ops under Obamacare. The co-ops were intended to help keep health care costs down by providing non-profit competition with commercial for-profit insurers. The losses do not include statewide costs where the state or local governments were forced to cover doctor and hospital bills that the failed co-ops could not pay from remaining revenues.
In many cases, those losses were substantial. In New York alone, state taxpayers face at least $200 million in costs owed to medical providers that the bankrupt Health Republic co-op could not cover, according to the Albany Business Review.
The remaining four are all barely surviving, and will likely fail themselves in the next few years, even if the Republican leadership goes chicken and delays the repeal of Obamacare while they haggle over what to do to replace it. What they should do is repeal it outright, and let that very weird and forgotten concept of freedom operate freely. I’ve heard it has worked very well in the past, though unfortunately most elected officials today are ignorant of that history.

Miyako Arishima – Nocturne in G major Op. 37 No. 2
An evening pause: In watching her play this Chopin piece the word that came to my mind was “graceful.”
Hat tip Edward Thelen.
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 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 pushes back first manned Dragon flight
The first flight of a manned Dragon capsule has been delayed about six months to May 2018.
SpaceX is now targeting a test flight taking two astronauts to the ISS in May of 2018 — about six months later than previously planned, but three months before Boeing aims to fly a similar test in its CST-100 Starliner capsule. The test flight with a crew will be preceded by an orbital flight without one that SpaceX now hopes to fly next November, again a six-month slip. Boeing plans its uncrewed test flight in June 2018
This delay had been expected. The key is to get both of these capsules operational before 2019, when our contract with the Russians to use their Soyuz capsule will expire completely.

OSIRIS-REx to search for Earth’s Trojan asteroids
As it heads outward for a rendezvous with the asteroid Bennu, OSIRIS-REx will turn on its instruments for 12 days in February 2017 to hunt for the Trojan asteroids that likely orbit the Sun in the Earth’s orbit 60 degrees ahead and behind it.
Six planets in our solar system are known to harbor Trojan asteroids — Jupiter, Neptune, Mars, Venus, Uranus and Earth. Although more than 6,000 Trojan asteroids are known to be orbiting along with Jupiter, scientists have discovered only one Earth Trojan to date: 2010 TK7, found by NASA’s NEOWISE project in 2010. Scientists predict that there should be more Trojans orbiting Earth, but these asteroids are difficult to detect because they appear close to the sun from Earth’s point of view. In mid-February 2017, however, the OSIRIS-REx spacecraft will be ideally positioned to undertake a survey of the stable point in front of Earth.
Over 12 days, the OSIRIS-REx Earth-Trojan asteroid search will employ the spacecraft’s MapCam imager to methodically scan the space where Earth Trojans are expected to exist. MapCam is part of the OSIRIS-REx Camera Suite, or OCAMS, which was designed and built by researchers at the UA’s Lunar and Planetary Laboratory.

Pennsylvania college students replace Shakespeare portrait with black author
The coming dark age: Students at the University of Pennsylvania have removed a portrait of Shakespeare, replacing him with a black author, because “he did not represent a diverse range of writers.”
It is very clear that these students have never read one word of Shakespeare, and thus are quite ignorant. It is also very clear that they are outright bigots, rejecting someone merely because of his skin color (white) to favor someone else merely because of their skin color (black).
The real tragedy here is that the university is apparently in agreement with the students. If I was sending my kids to college, this event would definitely place the University of Pennsylvania in the reject pile.
Correction: In my initial post I mistakenly described the private University of Pennsylvania as state funded. It is not, at least not directly. I have corrected the post accordingly.

Did a giant black hole eat a star?
New data now suggests that what astronomers had thought was the brightest supernova ever detect might have instead been the ripping apart of a star as it passed too close to a supermassive black hole.
In this scenario, the extreme gravitational forces of a supermassive black hole, located in the centre of the host galaxy, ripped apart a Sun-like star that wandered too close — a so-called tidal disruption event, something so far only observed about 10 times. In the process, the star was “spaghettified” and shocks in the colliding debris as well as heat generated in accretion led to a burst of light. This gave the event the appearance of a very bright supernova explosion, even though the star would not have become a supernova on its own as it did not have enough mass. The team based their new conclusions on observations from a selection of telescopes, both on the ground and in space. Among them was the NASA/ESA Hubble Space Telescope, the Very Large Telescope at ESO’s Paranal Observatory and the New Technology Telescope at ESO’s La Silla Observatory

Update on Progress/Soyuz launch failure
Link here It appears that the spacecraft separated from the upper stage while it was still firing, causing that stage to next collide with the spacecraft.
What is certain is that computers on Progress MS-04 interpreted the separation as nominal and initiated a sequence, which would be normally performed upon reaching orbit, including the deployment of the ship’s antennas and the preparation of the attitude control thrusters, DPO, for action. However, moments after the separation, the spacecraft appeared to be struck twice by the rocket stage, which clearly continued its powered flight. The first impact came nearly straight into the aft bulkhead of the ship, then the second hit landed moments later into the side of the vehicle.
The collision apparently caused the spacecraft’s propulsion system, SKD, to shift to the side from its normal position, the temperature inside its enclosure to plummet and the whole vehicle to tumble. The telemetry from the Progress also indicated the activation of its thermal control system, probably in response to a breach in the ship’s transfer compartment.
Why separation occurred prematurely, while the engines were firing, still remains a mystery.

Curiosity cleared to move but not drill
Engineers have cleared Curiosity to move once again, but have not yet cleared the rover to use its balky drill.
This morning we received downlink that indicated operation of the drill feed using standard commands. This is great news, and the anomaly response team has cleared the rover for use of the arm and driving (but not yet drilling).
It is not known when they will drill again, but the news suggests that they will do so eventually, once they get a full understanding of what prevented normal operations this last time. For moment, at least, they no longer have a need to keep the rover motionless so they could assess the situation.

India hires private companies to build satellite
The competition heats up: For the first time India’s space agency ISRO has signed a deal with a private consortium of private companies to have them build satellites.
The contract signed on Friday includes assembly, integration and testing (AIT) of two spare navigation satellites consecutively in around 18 months. It was signed between M. Annadurai, Director of ISRO Satellite Centre (ISAC), and the consortium lead, Alpha Design Technologies P Ltd. ISAC assembles the country’s satellites for communication, remote sensing and navigation.
From the third year, Indian industry could expect competitive bids for a new lot of spacecraft of 300-500-kg class, perhaps five a year, for both ISRO and for export, Col. H.S. Shankar (retd), CMD of Alpha Design, told The Hindu. This is the first time that ISRO has outsourced an entire satellite to industry, said Col. Shankar .
The Modi government appears to be trying here to emulate NASA in putting private companies in charge of construction, rather than having things designed and built in-house by ISRO. This is a very good sign. If they do it now, in the early days of their space effort, they can reduce ISRO’s ability to grow into a large bureaucracy with its own vested interests.

First dinosaur tail found, preserved in amber
Paleontologists have discovered the first completely preserved dinosaur tail, feathers and all, preserved in amber.
Inside the lump of resin is a 1.4-inch appendage covered in delicate feathers, described as chestnut brown with a pale or white underside. CT scans and microscopic analysis of the sample revealed eight vertebrae from the middle or end of a long, thin tail that may have been originally made up of more than 25 vertebrae. Based on the structure of the tail, researchers believe it belongs to a juvenile coelurosaur, part of a group of theropod dinosaurs that includes everything from tyrannosaurs to modern birds.

Democratic Senators force short government shutdown
Those racists! A handful of Democratic Senators have forced a government shutdown this coming weekend by refusing to allow the end of debate on a continuing resolution that would have funded the government through April.
Though I generally don’t agree with the reasons for this shutdown (they want to spend more money), I wish them luck, and would celebrate if this shutdown ended up lasting weeks. Unfortunately, according to some analysis, it can only last the weekend.
The biggest irony of this story is that the Democrats are forcing the shutdown to supposedly protect the pensions of coal miners, an industry they and Barack Obama successfully worked to destroy during the past eight years.
Update: Senator Joe Manchin (D-West Virginia) and the Democrats have backed down so that the shutdown was averted.
I am disappointed. I was really hoping they would do it. Every time there has been a shutdown it has clearly shown how little we need the federal government. The more the merrier, I say. Shut it down!

Juno’s upcoming December 11 Jupiter flyby
The Juno science team prepares for the next close flyby of Jupiter on December 11.
At the time of closest approach (called perijove), Juno will be about 2,580 miles (4,150 kilometers) above the gas giant’s roiling cloud tops and traveling at a speed of about 129,000 mph (57.8 kilometers per second) relative to the planet. Seven of Juno’s eight science instruments will be energized and collecting data during the flyby. “This will be the first time we are planning to operate the full Juno capability to investigate Jupiter’s interior structure via its gravity field,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. “We are looking forward to what Jupiter’s gravity may reveal about the gas giant’s past and its future.”
Mission managers have decided not to collect data with the Jovian Infrared Auroral Mapper (JIRAM) instrument during the December flyby, to allow the team to complete an update to the spacecraft software that processes JIRAM’s science data. A software patch allowing JIRAM’s operation is expected to be available prior to the next perijove pass (PJ4) on Feb. 2, 2017.
It increasingly appears they do not want to risk firing the spacecraft’s main engine to shorten the 53 day orbit to 14 days because of a fear that the burn could fail catastrophically. This means that Juno’s mission will be extended significantly because it will take longer to gather data with such a long orbit.

More members of Trump’s NASA transition team named
The NASA transition team for the upcoming Trump administration gained six new members today.
They range from people supporting the building of Aeroject Rocketdyne’s very expensive AR-1 engine to replace the Russian engines on the Atlas 5 to academics who have advocated, like me, dumping SLS and encouraging private space.

China preparing for anti-satellite test?
According to Pentagon officials China is preparing for a flight test of a new anti-satellite rocket.
Test preparations for the Dong Neng-3 anti-satellite missile were detected at a military facility in central China, according to Pentagon officials familiar with reports of the impending test. Intelligence agencies were alerted to the impending test by China’s announcement of air closure zones covering the expected flight path of the DN-3.
The flight test could come as early as Thursday, the officials said. No other details of the missile test were available. A Pentagon spokesman and a State Department official both said, “We do not comment on intelligence matters.”
One additional detail: The DN-3 rocket appears to be based on the Chinese commercial rocket Kuiazhou, which a Chinese launch company is pitching to the international market as a vehicle for putting smallsats into orbit.

Jupiter’s chaotic storms
Cool image time! The image on the right shows what anyone can do if they want to play with images that have been taken by the Juno spacecraft. On top is the raw Juno image of a storm on Jupiter. On the bottom is that same storm after significant processing by an ordinary citizen. A larger version can be seen here.
While the Juno science team’s policy of making all their raw images available to the public is routine for a NASA mission, they are doing something a bit different by allowing the public to play with the images and then upload them on a Juno website for everyone to see. While some of the subsequent images have been a little silly, the image on the right illustrates how this policy can help scientists (and the public) better study the atmosphere on Jupiter. The processing has brought out all the storm’s swirls and twirls, and shown clearly how chaotic the storms are in Jupiter’s high latitudes.
The scientists don’t have the resources or the time to do this kind of processing on every image, or even every piece of every image. Allowing the public to do it will increase the variety of results and make it more likely for everyone to gain some understanding of what is going on in the gas giant’s atmosphere. Or not, but then that’s okay, as a realization that we don’t understand something is the first step towards wisdom and real knowledge.

Dutch rightwing politician convicted by court for expressing anti-immigration opinions
Facists: The leader of the conservative and anti-immigration party in the Netherlands, Geert Wilders, has been convicted by a Dutch court of expressing hate speech during a political rally, simply because he called for a change in policy that would bring fewer Moroccans into the country.
Essentially, this liberal court has ruled that it is illegal for any politician, or anyone for that matter, to express an opinion in opposition to the present policy of the European Union to allow uncontrolled immigration into Europe from the Middle East. As noted at the link, “You read that correctly. An elected representative was convicted in a trial for talking about public policy. If that doesn’t send a chill down your spine then you are considerably more comfortable with socialism than you should be.”
This behavior of the left, however, is quite typical. They are fascists. You aren’t allowed to disagree with them, and if you do, they will work to destroy you. Think I am exaggerating? Consider these two stories from today:
- Mika Brzezinski: Clinton Campaign Tried To Get Me ‘Pulled Off Air’
- Orange Coast College Student Threatened With Expulsion After Recording Professor’s Anti-Trump Tirade

Facists: The leader of the conservative and anti-immigration party in the Netherlands, Geert Wilders, has been convicted by a Dutch court of expressing hate speech during a political rally, simply because he called for a change in policy that would bring fewer Moroccans into the country.
Essentially, this liberal court has ruled that it is illegal for any politician, or anyone for that matter, to express an opinion in opposition to the present policy of the European Union to allow uncontrolled immigration into Europe from the Middle East. As noted at the link, “You read that correctly. An elected representative was convicted in a trial for talking about public policy. If that doesn’t send a chill down your spine then you are considerably more comfortable with socialism than you should be.”
This behavior of the left, however, is quite typical. They are fascists. You aren’t allowed to disagree with them, and if you do, they will work to destroy you. Think I am exaggerating? Consider these two stories from today:
- Mika Brzezinski: Clinton Campaign Tried To Get Me ‘Pulled Off Air’
- Orange Coast College Student Threatened With Expulsion After Recording Professor’s Anti-Trump Tirade

The present strengths and limits to North Korea’s nuclear missile capabilities
Does this make you feel safer? A U.S. military official today outlined the strengths and weaknesses of North Korea’s aggressive effort to develop the capability of launch missiles with nuclear warheads.
North Korea appears able to mount a miniaturized nuclear warhead on a missile but is still struggling with missile re-entry technology necessary for longer range strikes, a senior U.S. military official said on Thursday. “I think they could mate a warhead with a delivery device. They’re just not sure (about) re-entry,” said the official, speaking to reporters on condition of anonymity. “They’re endeavoring to overcome that.”
North Korea has carried out repeated nuclear and missile tests this year in defiance of U.N. Security Council resolutions and sanctions and claims it has the capability to mount a nuclear warhead on a missile. Asked whether North Korea could mate the warhead to the missile, the official said: “I think they can.”

Japan successfully launches its ISS cargo freighter
Japan today successfully launched its sixth HTV unmanned cargo freighter to ISS.
The launch had been delayed from a September launch due to “leaking pipes”, whatever that means. Its successful launch now however relieves some of the supply pressure on ISS, caused by the failed launch of Russia’s Progress on December 1 and the September 1 Falcon 9 launchpad explosion.

Christmas in Hollis Carpool Karaoke
An evening pause: I normally don’t like rap, but this version of the Run-D.M..C. original is quite appealing, and very appropriate for the season.

Mars rover update: December 8, 2016
Curiosity
For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.
Since my last rover update on November 14th, Curiosity moved relatively little. They drove a short distance to the southeast to a point where they wanted to drill, but have not moved from this location for the past two weeks because of drill issues.
While the engineers study the drill problem, which requires them to not move either the rover or the drill arm, the scientists have still used Curiosity to take images of the dust in the sky, to take hourly images of the dust on the ground (to see how it is changed by the wind), and to take images of nearby interesting nearby features (below the fold).

Details revealed about Trump’s space policy?
Detailed comments by former congressman Robert Walker, who is advising the Trump transition team on space policy, yesterday provided some further hints at what the space policy will be during a Trump administration.
Walker said that there is an intent that the National Space Council be re-instituted so as to guide all space activities. civilian, military, and commercial. Walker went on to say that the Trump team is looking for a space policy that is “disruptive, resilient, and enduring”.
For one thing, Walker said that they are looking for a much longer life for the ISS – and that it will need to be refurbished and upgraded. He speculated that it would need to be handed over to an organization or consortium eventually. They are also looking for opportunities to have the commercial sector backfill for NASA so that NASA can focus on deep space exploration. Walker was very clear on this point noting that there was an awareness of many government programs that “take a decade to do with technology that ends up being out of date”.
…Walker was asked several times about SLS/Orion – in the context of Trump’s recent comments about Boeing and Air Force One. Walker did not answer the questions specifically but went into a broader generalization that Trump is not a politician but rather that he is a deal maker. He also thought that Trump’s funding of an ice rink in New York a few years back was a good example of what kind of president he’d be. Walker went on to say that Vice President-elect Pence would be the de-facto “prime minister” and run the government while Donald Trump went out to cut deals.
The issue of Earth science eventually came up. Walker said that the Trump administration is not looking to cancel NASA climate science but rather that they wanted to transfer all of it to other agencies who might have greater expertise. Earth centric research would be transferred so as to allow NASA to focus on space exploration.
It remains unclear whether SLS/Orion will survive a Trump administration. I suspect that at this point they themselves don’t know. They intend to shift climate research from NASA to NOAA, cutting some of that funding as they do so while also changing the personnel that run the research (thus cleaning house). They also probably want to shift NASA’s publicly-stated deep space goals back to the Moon, but this will simply be the empty rhetoric of politicians. More important is the suggestion that they want to extend the life of ISS. Such an action will also require an extension of the commercial crew/cargo contracts, which will also help continue to fuel the new space industry.

SpaceX’s loses launch contract due to scheduling delays
Because of SpaceX’s decision to delay its next launch into early January, Inmarsat today decided to switch launch companies for a mid-2017 satellite, dropping SpaceX and signing a contract with Arianespace.
Inmarsat is not abandoning SpaceX, only switching to Arianespace for one satellite. Nonetheless, this decision, coming only one day after SpaceX confirmed the delay, explains to me why SpaceX has been saying for months it intended to resume launches before the end of 2017. Inmarsat had probably told the company that if they delayed into January, they would lose this launch. When SpaceX finally admitted they couldn’t meet the 2016 launch deadline, Inmarsat made the switch.

Two new studies say different things about Greenland’s icecap history
The uncertainty of science: Two new studies of Greenland’s icecap suggest completely opposite histories, with one saying that Greenland was ice free at least once in the past 2.6 million years, with the other saying that the icecap covered Greenland continuously for the past 7.5 million years.
Evidence buried in Greenland’s bedrock shows the island’s massive ice sheet melted nearly completely at least once in the last 2.6 million years. This suggests that Greenland’s ice may be less stable than previously believed. “Our study puts Greenland back on the endangered ice-sheet map,” says Joerg Schaefer, a palaeoclimatologist at the Lamont-Doherty Earth Observatory in Palisades, New York, and co-author of a paper published on 7 December in Nature.
A second paper in the same issue paints a slightly different view of the ice sheet’s past stability. A group led by Paul Bierman, a geomorphologist at the University of Vermont in Burlington, found that ice covered eastern Greenland for all of the past 7.5 million years. Experts say the two papers do not necessarily contradict one another: at times, nearly all of Greenland’s ice could have melted (as seen by Schaefer’s team) while a frosty cap remained in the eastern highlands (as seen by Bierman’s group).
If all of Greenland’s ice melted, it would raise sea levels by seven metres. Models suggest that Greenland could become ice-free as soon as 2,500 years from now, depending on the concentration of greenhouse gases in the atmosphere. [emphasis mine]
This story is a perfect example of how the passionate belief in a theory (that global warming is happening, is a threat, and will melt the icecaps) can warp a scientist’s thinking. Both studies used a single drilled ice core, with the first from Greenland’s central region and the second from Greenland’s eastern region. Thus, there is no reason to say that the entire Greenland icecap had melted, as noted in the highlighted text that describes the first study. What the data merely suggests is that these two regions might have had different histories.
Instead, the article, in its effort to confirm the possibility that Greenland’s icecap could melt entirely and thus pose a threat of a big sea level rise, ignores this simple detail and struggles to justify the concept that the entire cap certainly melted in the past, even though one study suggests otherwise. This causes everyone to misunderstand the results, and draw conclusions that are uncalled for, based on the available data.
