The Clintons demand that unauthorized bios should not “be allowed”

5:09 pm

Fascists: Faced with the publication this year of three unauthorized biographies, the Clintons are demanding that such works “should neither be allowed or enabled.”

The Clintons’ prepared statement is very clear:

Their behavior should neither be allowed nor enabled, and legitimate media outlets who know with every fiber of their being that this is complete crap should know not to get down in the gutter with them and spread their lies. But if anyone isn’t sure, let’s strap all three to a polygraph machine on live TV and let the needle tell the truth. [emphasis mine]

As Ed Morrissey notes bluntly at the link, “Their behavior should not ‘be allowed’? What authority exists to bar these authors and their publishers (one of which is Regnery, like Hot Air a subsidiary of Salem Communications) from engaging in political speech? A better question: What authority do the Clintons propose to stop political speech?” [emphasis in original]

A Hubble Space Telescope status report

4:48 pm

Five years after the last shuttle repair mission, the Hubble Space Telescope continues to operate almost perfectly.

Jeletic said other than a single gyro failure, the observatory is operating in near-flawless fashion five years after the final shuttle crew departed. “Batteries are fine, solar arrays are fine, all the communications equipment is fine, we don’t see any glitches with the computers, the instruments are all fine,” he said. “In fact, an interesting statistic, the Advanced Camera for Surveys, which was repaired by the astronauts during the last servicing mission, that’s actually now run longer on the repair than it did originally for the Wide Field Camera part of it.”

The ACS, like the repaired Space Telescope Imaging Spectrograph, no longer has any internal redundancy. “It’s amazing. It truly is,” Jeletic said. “Given all the things that can fail, a lot of people were hoping for one or two years of continued work with it. Now we’ve gotten over five.” Likewise, the Space Telescope Imaging Spectrograph, which also is operating in “single-string” mode, is still going strong.

When they completed the 2009 servicing mission, the goal was to give Hubble five more years of operation. They’ve done that, and are now looking to keep the telescope going till at least 2020, marking 30 years in orbit.

The only issue, not surprisingly, is the failure of one of the six gyros on board. These have traditionally been the telescope’s biggest problem, and have been replaced twice over during shuttle missions. Three of today’s six however are using a new design which will hopefully extend their life significantly.

Fermi proves that novae produce gamma rays

12:56 pm

The Fermi Gamma-Ray Space Telescope has discovered that novae, small scale stellar explosions similar to some supernovae but far less powerful, also produce gamma rays when they explode.

A nova is a sudden, short-lived brightening of an otherwise inconspicuous star caused by a thermonuclear explosion on the surface of a white dwarf, a compact star not much larger than Earth. Each nova explosion releases up to 100,000 times the annual energy output of our sun. Prior to Fermi, no one suspected these outbursts were capable of producing high-energy gamma rays, emission with energy levels millions of times greater than visible light and usually associated with far more powerful cosmic blasts.

What is significant about this is that it demonstrates a solid link between novae and supernovae, since only recently have scientists shown that some supernovae also produce gamma ray bursts. It suggests that the two explosions are produced by somewhat similar processes, but at very different scales. This fact will have important ramifications in the study of stellar evolution and the death of stars. For example, some nova stars often go nova repeatedly. Other data suggest that some more powerful eruptions can be recurrent as well. Extending this recurrent pattern to supernova suggests many new theoretical possibilities.

CIA admits it hacked the Senate’s computers

12:40 pm

These people should be fired, then imprisoned: The CIA today admitted that illegally hacked into the Senate’s computer system.

Oh wait, I have a better idea! Let’s put them in charge of our healthcare and patrolling the borders and our tax system and space exploration and climate research and any number of other important issues of the day in which we need honesty, ethics, reliability, and competence!

A Democrat speaks, and lies spew out

10:06 am

We never tried to impeach Bush, says Democratic lawmaker who co-sponsored Bush impeachment bill.

What really depresses me about this story is not that the Democrat lied so blatantly but that she did so because she knew that her supporters are so wedded to her and her party that they will accept what she says without question. She knows she can get away with it.

In related news: “Want to see what liberals are really like? Then read our uncensored hate mail from the last three weeks.”

Mangement failures in Obamacare

9:45 am

Finding out what’s not in it: A new GAO report cites epic management incompetence in the Obama administration that caused the disastrous Obamacare website failure.

Among the issues, investigators found that the administration kept changing the contractors’ marching orders for the HealthCare.gov website, creating widespread confusion and adding tens of millions of dollars in costs. Changes were ordered seemingly willy-nilly, including 40 times when government officials did not have the initial authority to incur additional costs.

As a result, the government has spent $840 million on Healthcare.gov and its supporting systems, according to the report.

As I’ve said repeatedly, when you ask the equivalent of the Department of Motor Vehicles to run one-sixth of the U.S. economy, you are guaranteeing this kind of failure. Worse, it is not as if this hasn’t happened before. We have had plenty of experience with failed and bungled government operations in the past four decades. Why do we then demand that we entrust more of our lives to their control?

As Albert Einstein wisely noted, the definition of insanity is doing the same thing over and over again and expecting different results.

How the Earth gave the Moon a lemon shape

9:36 am

Scientists have found that the Earth’s gravity combined with the Moon’s rotation forced the satellite to become “lemon-shaped.”

As the Moon solidified, its rotation caused it to elongate along its polar axis. But because the length of the Moon’s rotation was the same as its orbit, with one hemisphere always facing the Earth, the tidal force of the Earth’s gravity then pulled at the center, distorting the Moon’s shape so that one hemisphere bulged Earthward.

This theory is not new, but these new calculations are more robust, lending greater weight to it.

The first lunar close-up

9:28 am

Fifty years ago tomorrow Ranger 7 took the first close-up images of the Moon, just before the spacecraft crashed onto the surface.

“It was like looking at a soft quilt or something, no jagged edges on anything,” muses Jim Burke, as if he’s describing something every school kid hasn’t seen a hundred times. “It looked like fresh snow in a way, except it was grey instead of white.”

At the time—50 years ago tomorrow—Burke was one of the first people on Earth to see what the surface of the Moon looks like up close. Early on the morning of July 31, 1964, he joined his colleagues in poring over a series of printed photographs, the pockmarked Moon getting closer and closer until one final blurred image marked the moment when Ranger 7 impacted the surface, making its own brand-new crater. A stripe of static along one side of that last photo indicated the interruption of the final transmission.

The article details the frustrating history of the Ranger program, with the first six attempts all failing. Ranger 7 succeeded, however, working so well that the last image actually got truncated at impact. The full set of images revealed the surprising cratered history of the Moon, with the impact rate of large to small craters far more complex than expected.

The early bombardment of the Earth

9:04 am

Using computer models based on the Moon’s crater record, scientists have developed a simulation of the great early bombardment of the Earth around 4 billion years ago.

The model suggests that the biggest asteroids to hit Earth would have been as large as 3,000 kilometres across. Between one and four would have been 1,000 kilometres wide or larger, it predicts, with a total of three to seven exceeding 500 kilometres in width. The most recent of these would have hit around 4.2–4.3 billion years ago.

In comparison with Earth’s mass, the amount of rock hitting the planet would have been tiny. But it would have had an enormous effect on Earth’s surface, says Marchi. A 10-kilometre-wide asteroid was enough to kill the dinosaurs, and studies4 show that one 500 kilometres across would vaporize all of the planet’s oceans. “At 1,000 kilometres, the effects would be so wide the planet would probably be completely resurfaced with material from the mantle,” he says.

Clarence White & Roland White – I Am A Pilgram/Soldiers Joy

6:01 pm

An evening pause: Performed live on Bob Baxter’s “Guitar Workshop” in 1973. Hat tip to jwing, who wrote the following when he sent me the link:

Clarence was instrumental in making flat-picking guitar a lead solo instrument in bluegrass, along with Doc Watson. He played as a session musician for many groups in the 60’s such as the Everly Brothers and The Monkees. Later he became the lead guitarist for Roger McGuinn’s Byrds. He developed the B-string bender invention that you can hear on the Eagles’ song “Take It Easy.” Sadly, in 1973 while packing up the band’s van after a late night gig he was hit by a drunk driver and was killed. A huge loss to music. This video was recorded in LA only a few months before that fateful night. Enjoy a true virtuoso.
