Theft by TSA employees of passenger valuables a nationwide problem

5:31 pm

Doesn’t this make you feel safer? Theft by TSA employees of passenger valuables has become a nationwide problem.

According to TSA records, press reports, and court documents . . . some 500 TSA officers . . . have been fired or suspended for stealing from passenger luggage since the agency’s creation in November of 2001. The airports servicing New York City—John F. Kennedy, LaGuardia, and Newark Liberty—harbor the most flagrant offenders, but virtually no city in the nation is safe from the TSA’s sticky fingers.

In 2009, a half dozen TSA agents at Miami International Airport were charged with grand theft after boosting an iPod, bottles of perfume, cameras, a GPS system, a Coach purse, and a Hewlett Packard Mini Notebook from passengers’ luggage. Travelers passing through the airport’s checkpoints reported as many as 1,500 items stolen, the majority of which were never recovered.

In May of this year alone, TSA agents were arrested on the suspicion of theft at airports in Los Angeles, Philadelphia, and Chicago.

The battle between global warming and the sun

3:59 pm

The revelation last week that the sun is very likely about to go into a period of little or no sunspot activity has made a lot of global warming advocates, both scientists and journalists, very nervous. For years these climate activists have declared that the Earth’s climate is getting warmer, and that this warming trend was going to do us great harm. Putting aside whether these claims are based on fact (they are not), the possibility that the Earth might instead become cooler because of a dimming of the sun puts this political agenda under threat, and requires some form of immediate action to defuse that threat. See for example this short podcast (with full transcript) from Scientific American. The key quote:

A cooler sun might mean a drop in global average temperatures of at most 0.3 degree Celsius. But the carbon dioxide already in the atmosphere today will add 0.6 degree Celsius to global average temperatures by the end of the century. And more, since greenhouse gas emissions show no signs of diminishing. So the slightly cooler sun won’t counteract a much hotter Earth.

In order to discredit the threat that solar variation poses to global warming, the journalist here acts to minimize any danger from a dimming sun. Unfortunately, he does so by extrapolating a result (warmer climates) based on a very weak foundation: an unproven theory and our very limited knowledge of the climate.

Cool images from Mars and Mercury

11:57 am

Here are two image releases of interest, one from Mars and one from Mercury.

Pavonis Mons pit

First the Mars image. This close-up image of a pit, requested by a seventh grade Mars student team at Evergreen Middle School in Cottonwood, California, shows more evidence of underground voids on Mars. The pit is located on the flank of one of Mars’ larger volcanoes, and suggests that there is a lava tube below it. At some point the roof over the tube at this point became unstable and collapsed, producing the surface pit.

A close-up image of the shadowed part of the pit with the exposure turned way up unfortunately shows that there is no skylight in the pit into the lava tube.

Next, the Mercury image, from Messenger.

How the recently dissolved California Space Authority wasted millions of dollars in federal earmarks and grants

How the recently dissolved California Space Authority wasted millions of dollars in federal earmarks and grants.

Sadly, this story is typical of many quasi-public/private authorities, most of which have nothing to do with the aerospace industry. There is a lot of one hand washing the other, using money the federal government nonchalantly gives away as if it is water.

Hadrian built his country estate with the buildings aligned with the sun

9:18 am

The Roman emperor Hadrian built his country estate with the buildings aligned with the sun.

For centuries, scholars have thought that the more than 30 buildings at Hadrian’s palatial country estate were oriented more or less randomly. But De Franceschini says that during the summer solstice, blades of light pierce two of the villa’s buildings.

In one, the Roccabruna, light from the summer solstice enters through a wedge-shaped slot above the door and illuminates a niche on the opposite side of the interior (see image). And in a temple of the Accademia building, De Franceschini has found that sunlight passes through a series of doors during both the winter and summer solstices.

Unmanned sail prototype prepares for launch

11:51 pm

A prototype of an unmanned sailing ship will begin a test voyage this fall.

Although Harbor Wing will operate without a captain and crew by sailing on a pre-programmed course, “the man is always in the loop,” Ott said. An operator, seated at a computer that could be hundreds of miles away, can control the craft with keystrokes that relay commands via satellite. The transmission gap, from order to receipt, is only 18 seconds, which “on the open ocean is not much,” he said, “so you have very close control.”

NASA about to decide on its shuttle heavy-lift replacement

5:56 pm

NASA is about to decide on its shuttle heavy-lift replacement, and it looks like it will be almost entirely shuttle-derived.

As I have said previously, this rocket will almost certainly never fly. NASA has to start over after spending billions and years developing Constellation, and is being given less money and time to do it.

And even if I am wrong and this rocket does fly, I bet it will do only one flight and then be retired as too costly.

Sheila Jackson Lee Likens Islamic Radicals to ‘Christian Militants’ in U.S.

11:28 am

An idiot speaks: Congresswoman Sheila Jackson Lee (D-Texas) yesterday equated Islamic terrorists with “Christian militants” in the United States.

Since 9/11 Islamic terrorists have carried out more than 17,000 attacks, killing tens of thousands. In that same time, you could count on one hand the number of attacks by “Christian militants,” if that many. For Representative Lee, it seems it is hard for her to tell the difference.

National Speleological Society responds to the demand that all caves be closed to protect bats

12:20 am

The National Speleological Society has responded in strong opposition [pdf] to the demand by the Center for Biological Diversity that all caves on public land be closed to protect bats.

Calling for blanket cave closures across the U.S. is unnecessary, unenforceable, and counterproductive. While cave closures on some federal lands have been implemented, particularly in the eastern U. S., there is no evidence that this action has done anything to contain [white nose syndrome] (WNS). Most people working on WNS understand that bat to bat transmission is overwhelmingly the primary method of transmission, and administrative closing of caves and mines does nothing to prevent that.
