Obama quarantines American soldiers in Africa but not Africans

10:09 am

Incompetence: Even as the Obama administration refuses to consider any real travel restrictions for African citizens of ebola-ravaged countries, it has ordered military officials to quarantine American troops in Africa for up to 21 days if they suspect they might have ebola.

According to CNN, “Commanders also will be given the authority to isolate their entire unit in the region for the final 10 days of a deployment if necessary. All troops will be monitored for 21 days after returning from the mission.”

Currently, citizens of Ebola outbreak countries are required to self-report their possible exposure. The “honor system” of self-reporting was violated by Thomas Eric Duncan, the Liberian man who was the first to be diagnosed with Ebola in the U.S., when he did not voluntarily disclose that he’d carried a pregnant woman in the throes of Ebola.

The restrictions for American troops actually does make sense. The lack of restrictions for Africans, however, is the height of blindness.

Three potential post-Pluto targets for New Horizons

9:01 am

After completing a deep search using the Hubble Space Telescope, scientists have identified three Kuiper Belt Objects (KBO) that New Horizons can actually reach after it flies past Pluto next year.

The KBOs Hubble found are each about 10 times larger than typical comets, but only about 1-2 percent of the size of Pluto. Unlike asteroids, KBOs have not been heated by the sun and are thought to represent a pristine, well preserved deep-freeze sample of what the outer solar system was like following its birth 4.6 billion years ago. The KBOs found in the Hubble data are thought to be the building blocks of dwarf planets such as Pluto.

I think it remarkable that in the vastness beyond Pluto they were able to find any objects that also happen to be within the narrow path that New Horizons must fly after it passes Pluto in July.

Democrats oppose an ebola travel ban

10:07 pm

Incompetence: Congressional Democrats have expressed strong opposition to any travel bans from ebola infected countries.

Remember, these are the same people who conceived, wrote, and passed Obamacare, without really reading it or even considering the concerns expressed by many people about the law (all of which have turned out to be true). Thus, it is not surprising they don’t have the brains now to recognize that a quarantine is exactly the right approach to handle ebola at this time, We have a very infectious disease that hasn’t yet broken out into the general populace which we can still keep confined to a small area, where we can more effectively fight it. A quarantine, enforced by a travel ban, will accomplish this.

But these Democrats care! So what they don’t have the ability to think? Let’s vote for them again!

Houston mayor says she will reduce scoop of pastor subpoenas

8:18 pm

How nice of her: The lesbian Democratic mayor of Houston has backtracked and promised to narrow the scope of the subpoenas her government issued to several pastors, demanding access to their sermons, speeches, and communications with church members.

She is still a fascist, as she is still going to go forward. She also has not yet specified exactly how she plans to narrow the scope of her demands, since as far as I can tell, none of her demands are constitutional or even reasonable.

40 to 63% increases in heath insurance premiums in Minnesota

5:45 pm

Finding out what’s in it: The health insurance premiums for one major Minnesota health insurance company are expected to increase by 40 to 63 percent in 2015.

The insurer started informing brokers Tuesday about rates for individuals if they renew coverage with the company for next year, said Heidi Michaels, an agent with the Dyste Williams agency in Minneapolis. In the half dozen consumer scenarios she’s looked at, Michaels said she’s consistently seeing premium jumps in the neighborhood of 40 percent to 60 percent. Her analysis, however, did not take into account significant discounts that consumers could see by way of federal tax credits, depending on their income. “They’re going to get substantial rate increases,” Michaels said in an interview Wednesday. “I haven’t seen one below 40 percent.”

Letters with these rate increases will go out the end of October, just before election day. (The company has pulled out of the government exchange, which means they don’t have to keep their rates secret until after the election, as required by the Obama administration, the most transparent in history!)

However, these rate increases indicate strongly how high the rate increases will be across the board. They are going to be ungodly high, possibly so high no one will be able to afford them.

Ice photographed in Mercury’s permanently shadowed craters?

12:08 pm

Kandinsky Crater on Mercury

Using Messenger, scientists think they have obtained optical images of the ice that is thought to exist in the permanently shadowed craters of Mercury.

Although the polar deposits are in permanent shadow, through many refinements in the imaging, the WAC [Messenger’s camera] was able to obtain images of the surfaces of the deposits by leveraging very low levels of light scattered from illuminated crater walls. “It worked in spectacular fashion,” said Chabot.

The team zeroed in on Prokofiev, the largest crater in Mercury’s north polar region found to host radar-bright material. “Those images show extensive regions with distinctive reflectance properties,” Chabot said. “A location interpreted as hosting widespread surface water ice exhibits a cratered texture indicating that the ice was emplaced more recently than any of the underlying craters.” In other areas, water ice is present, she said, “but it is covered by a thin layer of dark material inferred to consist of frozen organic-rich compounds.” In the images of those areas, the dark deposits display sharp boundaries. “This result was a little surprising, because sharp boundaries indicate that the volatile deposits at Mercury’s poles are geologically young, relative to the time scale for lateral mixing by impacts,” said Chabot. [emphasis mine]

The image on the right is of the crater Kandinsky, and shows a very intriguing bright area on the crater’s central peak.

I highlighted that one word in the the scientist’s quote above to emphasize how preliminary these conclusions are. The images are intriguing, but I would not at this time bet a lot of money on these conclusions. Ice might be the best explanation for this data, at this time, but I would not be surprised at all if later research finds this conclusion to be false.

The silent Obamacare protest of doctors

10:11 am

Faced with Obamacare’s high costs and deadening bureaucracy, doctors are finding ways to opt out.

Physicians across the country are responding to this evolution — most recently in response to the Affordable Care Act — by shielding their practices from government interference. This comes in many forms: Rejecting new Medicare and Medicaid patients, transitioning to third-party-free practices and ditching small private practices for employed positions with ever-larger hospital-owned networks.

Incompetence is incompetence, and if you are so stupid as to write an unworkable law that conservatives rightly predicted would do exactly the opposite of what you want — raise costs instead of lowering them, shrink health coverage instead of widening it, corrupt health care instead of improving it — than no one should be surprised if you exhibit incompetence in other areas as well. For example, the incompetence demonstrated by President Obama and the Democratic Party by imposing Obamacare on us is now being illustrated again in how Obama is handling the arrival of ebola on American shores: badly, foolishly, and with nothing but failure as a result.

First results back from the U.S. MAVEN Mars probe

9:13 am

Scientists have released the first results from NASA’s MAVEN probe orbiting Mars, designed to study that planet’s upper atmosphere.

As expected, the spacecraft has quickly found evidence of the Martian atmosphere leaking away into space.

Hydrogen appears to be leaving the planet’s atmosphere in clumps and streams that reach about 10 Mars radii into space, said Mike Chaffin, a MAVEN scientist also at the University of Colorado, who discussed the results at a 14 October news briefing. The hydrogen comes from water vapour that breaks apart in the upper atmosphere; because hydrogen is so much lighter than oxygen, it escapes into space relatively easily. “That’s effectively removing water from the Martian atmosphere,” says Chaffin.

Other images show oxygen and carbon drifting away from the planet, although these heavier atoms cluster closer to Mars than hydrogen. Deep within the atmosphere, oxygen forms ozone molecules that accumulate near Mars’s south pole.

Houston demands that pastors hand in their sermons on homosexuality or be held in contempt of court.

3:36 pm

Fascists: The city of Houston has issued subpoenas demanding that pastors hand in any sermons on the subjects of homosexuality, gender identity or the city’s first openly gay mayor Annise Parker or be held in contempt of court.

Among those slapped with a subpoena is Steve Riggle, the senior pastor of Grace Community Church. He was ordered to produce all speeches and sermons related to Mayor Annise Parker, homosexuality and gender identity. The mega-church pastor was also ordered to hand over “all communications with members of your congregation” regarding the non-discrimination law. “This is an attempt to chill pastors from speaking to the cultural issues of the day,” Riggle told me. “The mayor would like to silence our voice. She’s a bully.”

The only reason the city government and the mayor are demanding these sermons is to silence their opponents. Their actions are blatant violations of the first amendment and the freedom of speech, and are an effort to oppress any opposition to their own personal political agendas.

1 in 4 Americans can no longer afford to see their doctor

2:30 pm

Finding out what’s in it: Because of the high cost and high deductibles of Obamacare-mandated health insurance plans, 25% of Americans now believe they can no longer afford healthcare.

That any of these Americans are even considering voting Democratic in any future election is shameful. They conceived it, they wrote it, and then they shoved it down our throats, in one of the most partisan maneuvers ever seen in these United States. Until the Democratic party moves to fix the problems caused by this monstrous law — mostly by repealing it — they do not deserve the support of anyone.

Update on Bigelow’s ISS module

9:14 am

This article is a nice overview of Bigelow’s planned inflatable module for ISS, due to launch next year, and includes some good images.

I found this paragraph especially intriguing:

Earlier this year, Bigelow announced how much it’ll cost you to spend some time inside the BA 330 when it launches. Expect to pay $25 million for a sixty day lease of one-third of the station — if you can get yourself there and back. Should you need a ride, round-trip taxi service between SpaceX and your local launching pad will run you an additional $26.5 million.

That’s a total cost of just over $50 million for a sixty day stay in space.

Finding a meteorite 20 years after it hit the ground

8:32 am

By reanalyzing the data that had recorded the fireball twenty years ago, a team of meteorite hunters in the Czech Republic have finally located the remains of a meteorite that landed in 1991 but could not be found.

What is most interesting scientifically about their find is that the pieces they found were from different types of meteorites.

[T]hese four meteorites are of three different mineralogical types. This means that the Benešov meteoroid was heterogeneous and contained at least three different types of material. After the Almahata Sitta fall, this is the second time that such a heterogeneous composition has been found. It raises the possibility that a significant fraction of all asteroids are heterogeneous and that they were strongly reprocessed by collisions with other asteroids in the main belt.

In other words, the meteorite had been a conglomerate of different geological types, which were created in different environments and were later smashed together to form this one rock.

The Obamacare trifecta

10:08 am

A very detailed and accurate description of the disaster that is Obamacare. Key sentence:

Over the next couple of years, I will lose my doctor, I will lose my plan and my healthcare costs will increase.

Read it all, and remember that this disaster is coming to all of us in the coming years. Note also that just because the Obama administration is delaying the release of next year’s ballooning health insurance premiums until just after the election does not require us to be stupid and to make believe these increases aren’t going to happen. They are, because the design of Obamacare rations treatment, imposes unneeded costs on everyone, and stifles the free market (which is the best tool for keeping costs down).

And then there’s this: “Grim milestone: Semi-retired president plays 200th round of golf in office.”

Why NASA picked Boeing over Sierra Nevada

9:43 am

A NASA internal document obtained by Aviation Week outlines the agency’s reasons for rejecting Sierra Nevada and its Dream Chaser spacecraft in its commercial manned space program.

Although the document praises Sierra’s “strong management approach to ensure the technical work and schedule are accomplished,” it cautions that the company’s Dream Chaser had “the longest schedule for completing certification.” The letter also states that “it also has the most work to accomplish which is likely to further extend its schedule beyond 2017, and is most likely to reach certification and begin service missions later than the other ‘Offerors’.”

Discussing costs, Gerstenmaier says that “although SNC’s [Sierra Nevada] price is lower than Boeing’s price, its technical and management approaches and its past performance are not as high and I see considerably more schedule risk with its proposal. Both SNC and SpaceX had high past performance, and very good technical and management approaches, but SNC’s price is significantly higher than SpaceX’s price.”

The document essentially was written, and probably leaked to the press now, to justify the political decision to give the contracts to Boeing and SpaceX. Thus, it waxes very enthusiastic about Boeing, since giving Boeing the contract, with the highest price and the least metal cut, needs some justification.

Recent volcanism on the Moon

4:53 pm

New data from Lunar Reconnaissance Orbiter suggests that lunar volcanism petered out slowly and occurred more recently that previously believed.

NASA’s Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon’s volcanic activity slowed gradually instead of stopping abruptly a billion years ago. Scores of distinctive rock deposits observed by LRO are estimated to be less than 100 million years old. This time period corresponds to Earth’s Cretaceous period, the heyday of dinosaurs. Some areas may be less than 50 million years old. Details of the study are published online in Sunday’s edition of Nature Geoscience. “This finding is the kind of science that is literally going to make geologists rewrite the textbooks about the moon,” said John Keller, LRO project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

In a way, this new conclusion is an example of science discovering the obvious. It seems to me quite unlikely that volcanic activity on the Moon would have “stopped abruptly” under any conditions. That’s not how these things work.

Orbiting X-37B to land on Tuesday

9:08 am

After twenty-two months in orbit, on its second space mission, the Air Force plans to bring the X-37B back to Earth this coming Tuesday.

The exact time and date will depend on weather and technical factors, the Air Force said in a statement released on Friday. The X-37B space plane, also known as the Orbital Test Vehicle, blasted off for its second mission aboard an unmanned Atlas 5 rocket from Cape Canaveral Air Force Station in Florida on Dec. 11, 2012. The 29-foot-long (9-meter) robotic spaceship, which resembles a miniature space shuttle, is an experimental vehicle that first flew in April 2010. It returned after eight months. A second vehicle blasted off in March 2011 and stayed in orbit for 15 months.

Yutu is slowly dying

4:00 pm

China’s lunar rover Yutu, unable to move since its first few weeks on the moon, is slowly dying.

The rover is currently in good condition and works normally, but its control problem persists, said Yu Dengyun, deputy chief designer of China’s lunar probe mission. “Yutu has gone through freezing lunar nights under abnormal status, and its functions are gradually degrading,” Yu told Xinhua at an exclusive interview. He said that the moon rover and the lander of the Chang’e-3 lunar mission have completed their tasks very well. The rover’s designed lifetime is just three months, but it has survived for over nine.

As China’s first planetary rover mission, the limited roving success of Yutu is well balanced by its ability to continue functioning on the lunar survey for so long. The engineering data obtained from this mission will serve Chinese engineers well as they plan future missions.

SpaceShipTwo poised for powered test flights

3:51 pm

Virgin Galactic officials outline the status of SpaceShipTwo, suggesting that powered flight tests are finally about to begin.

Providing a rare glimpse of progress on a second spacecraft under assembly at sister organization, The Spaceship Co., Virgin Galactic Vice President of Operations Mike Moses says, “we are ready for space.” A former NASA launch integration manager for the space shuttle, Moses adds that SS2 “has been in modification, getting retrofitted ready to resume powered flights.” He notes that “those are going to start imminently—literally very imminently.”

Commenting on the extensive gap between now and the last rocket flight in January, Moses says, “It might seem a long time since our last powered flight-testing and that maybe nothing has been happening, but [ground testing] has been happening.” Tests have largely focused on ground-firings of a hybrid rocket motor fueled with polyamide-based plastic in place of the hydroxyl-terminated polybutadiene, a form of rubber used for the first series of powered tests. Although this fuel had been used successfully in SpaceShipOne, the vehicle developer Scaled Composites and Virgin Galactic encountered fuel-burn stability and power issues as they tried to scale the Sierra Nevada Corp.-provided hybrid motor up to the size required by the larger SS2.

It appears my guess was right and that the last two glide tests were to retrofit SpaceShipTwo for the new fuel and engine. This has now been accomplished, and they are preparing to begin powered flight tests.

The article also describes work on a second SpaceShipTwo, which when completed will give Virgin Galactic the beginnings of a fleet of ships.

New measurements cut dark matter in Milky Way by half

7:10 pm

The uncertainty of science: New more robust measurements by Australian astronomers has shown that the amount of dark matter in the Milky Way galaxy is about half of what previous measurements had estimated.

Without doubt something is causing the outer stars in galaxies to orbit their galaxies at much greater speeds than they should. The answer that astronomers have posited since the late 1950s is that there is additional unidentified mass, dubbed dark matter, lurking as a halo around each galaxy, pulling on those outer stars and making them move faster.

The problem remains that no one has as yet detected this unidentified dark matter. Moreover, there are enormous uncertainties in the measurements of the motions of stars. This result helps narrow those uncertainties.

EPA tells court it has lost text messages

3:21 pm

The most transparent administration ever: The EPA has admitted that text messages demanded in a lawsuit, which the agency is required by law to retain, have been lost.

The Environmental Protection Agency (EPA) told a federal court that it may have lost the text messages at the center of a lawsuit by a libertarian think tank.The Competitive Enterprise Institute (CEI) sued the EPA last year in federal court to compel the release of text messages to and from Administrator Gina McCarthy and her predecessor under the Freedom of Information Act. In the Tuesday filing to the United States District Court for the District of Columbia, Justice Department lawyers representing the EPA said the agency will soon file a notice that it may have misplaced records that it was legally required to retain.

It seems pretty clear that the Obama administration has decided to follow the same playbook with all its many scandals: stonewall and coverup, legally or illegally.

Construction of Angara launchpad at Vostochny delayed

9:23 am

In order to complete construction of the Soyuz rocket launchpad at Russia’s new spaceport in Vostochny as quickly as possible, Russian managers have decided to delay completion by one year of the launchpad for the new Angara rocket.

I would not conclude from this decision that the construction at Vostochny is lagging. Instead, it appears that the Russian government continues to give it a high priority, and is merely beginning to structure that priority as effectively as possible. The Soyuz rocket is already in operation and will be ready to fly as soon as Vostochny is operational. Angara meanwhile is still under development. I suspect a delay in getting its launchpad ready will have no effect in the overall schedule of that rocket, as they need to do several additional test flights before it will be ready to be declared operational.
