Obamacare poll numbers crash
Finding out what’s in it: New polls show that the more the public becomes familiar with Obamacare, the more they hate it.
Hey, what’s not to like? Obamacare gives you higher premiums, less availability of doctors, less insurance coverage, more bureaucracy, more paperwork, and — best of all! — increased government interference in your life.

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, 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
British medical journal bans Israelis
Modern debate: The British medical journal, The Lancet, has banned Israeli academics from responding to any anti-Israeli papers that it publishes.
You’d think these Israelis were skeptics of climate change or something.

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.

Eta Carinae’s next big show
Astronomers are gearing up to observe the next binary fly-by of Eta Carinae’s companion star over the next few weeks.
A binary system, η Carinae has two stars that swing past one another every 5.5 years. The bigger star — some 90 times the mass of the Sun — is incredibly unstable, always seemingly on the verge of blowing up. When the smaller companion star makes its closest approach to the primary star, as is happening now, the interaction between the two triggers violent changes in the high-energy radiation pouring out of the system.
Astronomers are watching the show in the hope of learning what drives this enigmatic system. In the 1840s, η Carinae had a mysterious eruption; in recent decades, it has again brightened unexpectedly. “The star is in an awfully deranged state, and no one knows why,” says Kris Davidson, an astronomer at the University of Minnesota in Minneapolis.
Eta Carinae is also famous because it was one of the first objects imaged by Hubble after its repair in 1993, and was thus the first stellar explosion ever caught on camera in a visually sharp and clear manner. (See my book The Universe in a Mirror for that fascinating story.)

Video of the Falcon 9 first stage doing a soft splashdown
Video taken from a chase plane during the July 14 Falcon 9 launch shows the first stage appearing from out of the low clouds, engines firing, vertical and ready for landing. The video, below the fold, also shows the stage slowing just before it hits the water, much like the test vehicles Grasshopper and Falcon 9R do.
Though SpaceX has already claimed their first stage had done this during the July 14 launch, this video proves it. All they need to do now to recover their first stage is to direct it to a land-based landing site.

Comet 67P/C-G at 126 miles
The image above was taken by Rosetta on August 4 from only 126 miles (234 kilometers). Unlike earlier images, this image is raw, uncropped and unprocessed. All I have done is rescale it to fit on my webpage. As they explain at the link,
As you can see, the comet is not centred in the full-frame image. This is a result of the rendezvous burn conducted the previous day, which adjusted Rosetta’s trajectory towards the comet. This effect is corrected for in the commands sent to the spacecraft after the new orbit has been determined.
The science team also notes that beginning tomorrow, the comet will be close enough that they will no longer have to provide a cropped close-up using the navigation camera and that this uncropped raw version will be sufficient.

An exoplanet that was once like a star
Astronomers, using WISE data, have discovered a strange exoplanet that is now as cool as a rocky planet, but was once as hot as a red dwarf star.
The current temperature of the object is 100-150 degrees Celsius, intermediate between that of the Earth and Venus. But the object shows evidence of a possible ancient origin, implying that a large change in temperature has taken place. In the past this object would have been as hot as a star for many millions of years.
Called WISE J0304-2705, the object is a member of the recently established “Y dwarf” class – the coolest stellar temperature class yet defined, added to the end of the sequence OBAFGKMLT (for historical reasons this is not in alphabetical order but follows a decline in temperature from O to T). Although its temperature is not far off that of our own world, the object is not like the rocky Earth-like planets and instead is a giant ball of gas like Jupiter.
As cool as this discovery is (no pun intended), I am most enlightened by the information in the second paragraph above. I had not realized that astronomers had added L, T, and Y classes to the low temperature end of their stellar classification system. For those new to astronomy, you remember the sequence of the first seven classes with the phrase “O Be A Fine Girl Kiss Me”. I wonder what how we can amend this phrase to include the L, T, Y, classes?

Another successful SpaceX commercial launch
The competition heats up: After a launch abort at T-12 seconds, the countdown was recycled and SpaceX’s Falcon 9 rocket lifted off at the very end of its launch window early Tuesday morning, putting an Asiasat communications satellite into orbit.
They still have to fire the thrusters to get the satellite to geosynchronous orbit.

U.S./Russian owned launch company ILS cuts workforce by 25%
The competition heats up: Business loses because of its recent Proton launch failures, combined with strong market competition from SpaceX, today forced International Launch Services (ILS) to cut its work force by 25%.
The company is anticipating a launch rate drop from an average of 7 to 8 missions a year down to 3 to 4. The article also noted one more additional detail that will affect the future market value of Proton:
So far in 2014, the commercial satellites ordered have been mainly at the lighter end of the market for geostationary-orbiting telecommunications spacecraft. This follows a couple of years in which heavier satellites dominated.
Commercial Proton rockets are typically used to launch heavier satellites one at a time. The market’s move to lighter spacecraft has benefited Space Exploration Technologies Corp. of Hawthorne, California, whose Falcon 9 rocket has accumulated commercial orders; and also benefited Arianespace, whose Ariane 5 heavy-lift vehicle’s lower position is reserved for smaller satellites.
The weight of commercial satellites is almost certainly going to continue to drop in the coming years as technology improves and satellite companies work to reduce the cost to launch. In that climate, the Proton’s ability to put big commercial payloads into orbit will become a liability, not an asset. Ariane 5 has the same problem, in that it still needs a big payload for its upper position in order to make a launch cost effective.
Both Falcon 9, with its very low launch costs, and Russia’s new Angara rocket, with its modular design to handle all kinds of payload sizes, are better suited to this new competitive market.

SpaceX strikes deal with Texas to build spaceport
The competition heats up: Texas today announced an agreement with SpaceX, finalizing the company’s plans to build the world’s first commercial spaceport near Brownsville, Texas.
More here. The deal remains contingent on SpaceX getting all required permits from the federal government, but I doubt that will be a problem.

An Amtrak train abandons all of its passengers
Government-run transportation: An Amtrak high-speed train left New York City this weekend without its passengers, who were instead waiting to board on a different platform where railroad employees had sent them.
“They literally sent us to the wrong platform, and the conductor took off without any passengers,” Damien Miano, a stranded passenger told The Daily News. “The right hand didn’t know what the left hand was doing. It’s just so bizarre.”
Amtrak might make believe that it is a private company, but it has been a government entity for decades. Like the post office, it has no real incentive to make a profit and operate efficiently since all losses get covered by the federal government.

Hamas propaganda becomes Israeli comedy
At the start of the Gaza war four weeks ago Hamas released a propaganda music video calling for the destruction of Israel and for Palestinians to “exterminate the roaches.”
The problem was that the video was in Hebrew, not Arabic, and Israelis have found it hilarious and have made it a summer music sensation!
Surprisingly, though, Israelis found the tune of “Attack! Carry Out Terror Strikes” extremely catchy. Making it even more fun was the flowery Hebrew, dotted with nonexistent words sung in a heavy Arab accent, all of which led to the song’s becoming a summer hit. It has since spawned numerous covers and tributes.

Market Street, San Francisco, April 14, 1906
An evening pause: This film footage has been circulating about on the web for several years. I even think I posted it previously but can’t find that post now. Either way, it was shot mere days before the San Francisco earthquake, and provides us a window into the reality of life then. The sound effects add to the reality, though they are not original to the time. They were added later and were dubbed in with what I think was great care. See the notes here for more details.

The library that tried to ban conservative news researchers backs down.
Victory for free speech: The University of Arkansas has backed down from its attempt to ban a news research team because it was using that research to publish articles critical of Hillary Clinton.
The University of Arkansas library has backed down from its decision to block the Washington Free Beacon from accessing its special collections archives following a month-long public uproar. The library suspended the Free Beacon’s research privileges in June after the outlet published a story based on audiotapes from university archives that included Hillary Clinton discussing her 1975 defense of a child rapist.
The article clearly documents that the university was working on behalf of Hillary Clinton and the Democratic Party, trying to impose the ban for political reasons.

Scientists struggle with earthquake data in the Pacific northwest
The uncertainty of science: A second look at cores drilled in the Pacific northwest has raised doubts about the previous conclusions that the region faces the threat of megaquakes every few centuries.
The bottom line is that though geologists are very confident the northwest faces the threat of future quakes, they can’t yet predict with any confidence their rate or intensity.

The next U.S. Mars rover will try to make and store oxygen
Of the seven science instruments proposed for the next U.S. Mars rover, scheduled for a 2020 launch date, MOXIE test the engineering to produce and store oxygen, pulled from the Martian atmosphere.
Developed in partnership with NASA’s Jet Propulsion Laboratory, it’s based on the fact that the Martian atmosphere, though extremely thin, is composed of 96 percent carbon dioxide, which means its a vast potential source of oxygen for future explorers and settlers. Essentially, MOXIE is a fuel cell in reverse. Instead of generating electricity by using oxygen to burn a fuel, it uses a process called solid oxide electrolysis , where electricity is employed to split carbon dioxide into oxygen and carbon monoxide.
This process would see Martian air pumped into the unit through a dust filter and pressurized before being passed into a fuel cell. At high temperatures, some ceramic oxides act as oxygen ion conductors. In the fuel cell, a thin, non-porous disc of this ceramic separates two porous electrodes. One electrode acts as the cathode and the other as the anode. Carbon dioxide passes through the cathode and when it comes into contact with the ceramic, the interaction of electricity and the ceramic causes the carbon dioxide to split into oxygen and carbon monoxide. The oxygen and the carbon monoxide are then separated and the oxygen stored.
What makes this unusual is that NASA has actually dedicated one science instrument to engineering research, not pure science. The agency does not do this much anymore, but such research is essential if the U.S. is going to someday send humans to other planets.

Ukraine tensions disrupt more U.S.-Russian science
It appears that several U.S. scientists have been forced to cancel their appearances at science conferences in Russia because of the increased tension between the U.S. and Russia over Ukraine.
The disruptions seem to be almost random and are not being applied across the board, as the story also notes that many other programs are not being affected at all.

SpaceX’s next commercial launch set for tomorrow
The competition heats up: Just three weeks after its previous commercial launch SpaceX is scheduled to put AsiaSat 8 into orbit at 1:25 am tomorrow.
If Tuesday morning’s launch goes well, SpaceX will follow it with another commercial launch just three weeks later, also for Asiasat.
The article above notes how this will be the first launch for Asiasat from the U.S. in more than a decade. They had switched to Russian launchers because of cost and the difficulties of working under U.S. security requirements. The security problems still remain, but might be solved if SpaceX builds its own private spaceport.
William Wade, AsiaSat president and CEO, is excited for the upcoming launches, but confirmed the company’s experience here has not been as easy as at other launch sites. Access to Cape Canaveral Air Force Station for roughly 60 employees, shareholders and customers now in town — most not U.S. citizens and many who are Chinese nationals – has been difficult. “That is proving to be somewhat cumbersome,” Wade said. “We have to go through all the security clearances, which is expected, but we are finding as a foreign company that it is a bit more difficult conducting our launches there.”

Russian umanned space program pushed back three years
Because of the increased workload imposed on Russia when the U.S. suddenly pulled out of the European ExoMars mission, the Russians have imposed a three year delay on their entire program of unmanned science probes.
Although all previously approved projects still remain on the table, the nation’s series of lunar missions face a domino effect of delays. Russia’s first post-Soviet attempt to land on the surface of the Moon was pushed back from 2016 to 2019. Known as Luna-Glob or Luna-25, the unmanned lunar lander was designed to test landing techniques for future lunar missions. On the political front, the successful landing of the Luna-Glob would be a signal to the international scientific community that Russia is back in the planetary exploration business after the 2011 fiasco of the Phobos-Grunt mission.
This report above is a more nuanced analysis than yesterday’s story about the presentation given by the head of the Russia’s Space Research Institute at Saturday’s science conference in Moscow. Today’s story gives the reasoning for the delays, as explained by the Russians themselves, as well as outlines the entire program more thoroughly.
The story describes a string of planned Russian lunar probes, beginning with Luna-Glob. This program was probably approved by the government when the U.S. decided to return to the Moon in 2004 under George Bush. The Russians don’t seem to be able any longer to be self-starters, but instead need the competition from the U.S. to get them jump-started.
Even so, while the U.S. has already flown most of the unmanned probes to the Moon that were proposed in 2004, the Russian program had not yet gotten off the ground.

67P from less than 200 miles
Today’s Rosetta image of Comet 67P, shown above, gives us a different angle of the comet. The spacecraft was only 186 miles (300 kilometers) away when it snapped the picture, and this side view emphasizes the nucleus’s jagged shape.
I am reminded of what happens to a block of ice when you spray warm water on it. It begins to melt away, but very randomly and unevenly, producing very weird shapes and the surface evaporates off. In the case of Comet 67P, the nucleus is a dirty ball of ice, and the Sun’s rays have been causing its surface to evaporate off every time it approaches the Sun. Thus, we get a very weird shape.

Russia outlines its space exploration plans for the next two decades
At a science conference in Moscow on Saturday the director of Russia’s Space Research Institute described in detail the future exploration plans for the Russian space program.
According to the story, Russia plans to return to the Moon and Mars with unmanned probes. He also described how the first missions will be in partnership with Europe, followed by Russian missions designed to test and prove the technologies. If these flights go well, in 2024 Russia will consider trying again with a repeat of the Phobos-Grunt mission that failed in 2012
This last detail is a change from previous reports that said Russia would launch Phobos-Grunt 2 in 2018. It is also consistent with much of the Russian program for the last two decades (as well as most of NASA’s own ambitious manned exploration program), where the agency makes bold announcements of future plans but somehow with each new announcement the dates for the actual launch have always been pushed back. The actual flight never seems to happen.
At a science conference in Moscow on Saturday the director of Russia’s Space Research Institute described in detail the future exploration plans for the Russian space program.

Today’s Comet 67P image
The image above was taken on August 2 using Rosetta’s navigation camera. It has been processed by the science team to bring out the details. I have also rotated it to match the August 1 image taken at a distance of 620 miles that was taken by Rosetta’s OSIRIS narrow angle camera, designed to do the actual science.
You can see that the navigation camera does a pretty good job on its own of capturing the comet’s nucleus. Both images show that the instruments are working perfectly, and thus tell us that the next few months will be quite spectacular after Rosetta goes into orbit in three days, followed in November by the landing of Philae somewhere on the comet’s surface.
If you download both images and then switch back and forth between them you can get a better feel for the geometry of the surface features.

Ebola patient arrives in U.S.
Doctors in charge of the specialized isolation unit for treating dangerous infectious diseases are confident that they will be able to treat the infected patients safely without the disease escaping.
I have complete confidence that a well run facility like this, with modern technology, could keep the disease isolated. The key words, however, are “well run.” I pray that this description still applies to Emory University Hospital.
