Scientists have released some results, including video, from their look at asteroid 2012 DA14 during its fly-by last week. Key quote:

The asteroid’s path was perturbed by Earth’s gravitational field in such a way that it won’t come as close in the foreseeable future.

The video, which I have embeded below the fold, was produced from radar data. It clearly shows the asteroid’s rotation.

A new poll of Earth scientists has found that a majority are skeptical of human-caused global warming.

Consensus! A new poll of Earth scientists has found that a majority are skeptical of human-caused global warming.

Only 36 percent of geoscientists and engineers believe that humans are creating a global warming crisis, according to a survey reported in the peer-reviewed Organization Studies. By contrast, a strong majority of the 1,077 respondents believe that nature is the primary cause of recent global warming and/or that future global warming will not be a very serious problem.

This is fun to note, but this poll is as worthless in determining the climate of the Earth as every previous poll that said the opposite. What matters is the data. However, this quote about the poll is significant:

Two days ago the Congressional Budget Office increased its projection for the cost of Obamacare by 29 percent, while also saying that seven million workers will lose their health insurance due to the law, almost twice as many as previously estimated.

Not fit to print: Two days ago the Congressional Budget Office increased its projection for the cost of Obamacare by 29 percent, while also saying that seven million workers will lose their health insurance due to the law, almost twice as many as previously estimated.

As noted at the link, not one news organization has seen fit to mention this juicy tidbit in their news reports. I wonder why?

Meanwhile, we will go bankrupt. This law, and the government that is imposing it on us, is unsustainable.

A gun control bill introduced in Washington includes a provision that allows the police to conduct yearly house searches, without a warrant, of any gun owner’s home.

The fascists are out: A gun control bill introduced in the state of Washington includes a provision that allows the police to conduct yearly house searches, without a warrant, of any gun owner’s home.

Such searches would violate the fourth amendment of the Constitution, and in my case, any cop who showed up at my door would be politely told that I do not consent to any searches, without a warrant. They don’t get in my door.

Meanwhile, the Democrats who sponsored this bill, without reading it of course, are now tripping over themselves to disavow it, as if that would somehow make everyone forget that they introduced it.

The abandoned calibration targets used by surveillance satellites of the 1960s.

The abandoned calibration targets used by surveillance satellites of the 1960s.

“There are dozens of aerial photo calibration targets across the USA,” the Center for Land Use Interpretation reports, “curious land-based two-dimensional optical artifacts used for the development of aerial photography and aircraft. They were made mostly in the 1950s and 1960s, though some apparently later than that, and many are still in use, though their history is obscure.”

Mercury, in full color.

Mercury, in full color.

Scientists working with NASA’s Messenger probe have produced a global color map of the surface of Mercury, closest planet to the Sun. Thousands of sets of images were enhanced then stitched together in a mosaic to create a detailed image covering the entire planet.

Largest in a century.

More on today’s Russian meteorite: Largest in a century.

My earlier skepticism appears incorrect. This impact actually happened.

Note the article’s sense of outrage and panic that we aren’t looking for these types of rocks:

Although a network of telescopes watches for asteroids that might strike Earth, it is geared towards spotting larger objects — between 100 metres and a kilometre in size. “Objects like that are nearly impossible to see until a day or two before impact,” says Timothy Spahr, Director of the Minor Planet Center in Cambridge, Massachusetts, which tracks asteroids and small bodies. So far as he knows, he says, his centre also failed to spot the approaching rock.

Yet, today’s impact actually illustrates the wisdom of excluding this kind of small asteroid from searches. They aren’t big enough to do serious harm, and trying to find them would hamper searches for larger asteroids that do pose a serious risk.
