High school student arrested for writing he killed his neighbor’s dinosaur with a gun

4:31 pm

Madness: A South Carolina high school student was arrested for writing — in a “What-I-did-during-summer-vacation” school assignment — that he killed his neighbor’s dinosaur with a gun.

Investigators say the teacher contacted school officials after seeing the message containing the words “gun” and “take care of business,” and police were then notified on Tuesday. Summerville police officials say Stone’s book bag and locker were searched on Tuesday, and a gun was not found. According to police, when Stone was asked by school officials about the comment written on the assignment, he became “very irate” and said it was a joke. A Summerville Police Department report states that Stone continued to be disruptive and was placed in handcuffs, and was told that he was being detained for disturbing schools.

The police are claiming that he was arrested because of his behavior when questioned. I don’t blame him. I think the teacher who reported him and the school officials who called the police should be fired immediately for downright stupidity. Such people are not competent to teach the young.

A new map of the Middle East

10:38 am

Link here. The wide extent of Islamic State control is scary. It is also interesting that all of the U.S. airstrikes are outside those areas. At first glance it appears that we have terrible aim and are missing our targets. It is more likely that these are areas of dispute and we are supporting Iraqi and Kurdish efforts to regain the initiative.

The weight of Comet 67P/C-G

10:26 am

Scientists, using radio and orbital data from Rosetta, have made their first estimate of the mass of Comet 67P/C-G.

For the Rosetta mission, this task comes under the umbrella of the Radio Science Investigation (RSI). Using 80 hours worth of tracking data between 6 August, since arriving at the comet, and up to 9 August, the RSI team made a first estimate of the comet’s mass as approximately 1×10^13 kg +/-10%, or about 10 trillion kilograms.

This is very much a preliminary number which will be refined significantly as the spacecraft continues its travels with the comet.

More here. This mass, when considered in conjunction with the nucleus’s size, suggests a very low density. If you could find an ocean large enough it would float.

Arianespace and ESA sign contract for three launches

9:53 am

Arianespace and the European Space Agency (ESA) signed a contract on Thursday for the Ariane 5 rocket to launch 12 more of Europe’s Galileo GPS satellites on three launches.

This contract is a perfect example of European pork. Europe’s Galileo system might provide competition to the U.S. GPS and Russian Glonass systems, but I am not sure what additional capabilities it provides that will convince GPS users to switch to it. Instead, building it provides European jobs, while using the Ariane 5 rocket to launch it gives that increasingly uncompetitive rocket some work to do. In fact, this situation really reminds me of the U.S. launch market in the 1990s, when Boeing and Lockheed Martin decided that, rather than compete with Russia and ESA for the launch market, they instead decided to rely entirely on U.S. government contracts, since those contracts didn’t really demand that they reduce their costs significantly to compete.

Europe now appears to be heading down that same road.

Two additional Russian rocket engines arrive in the U.S.

9:38 am

Despite tensions over the Ukraine, a Russian cargo plane on Wednesday delivered two more Russian rocket engines to Alabama for their refurbishment and use in ULA’s Atlas 5 rocket.

This delivery gives ULA some additional breathing room. It the additional deliveries scheduled for later this year and early in 2015 happen, they will have even more breathing room for more Atlas 5 launches. Even so, their dependence on Russian engines is something that limits the company’s competitiveness in the emerging aggressive launch market.

NASA’s Space Launch System searches for a mission

9:26 am

Managers of NASA’s Space Launch System (SLS) are searching for a mission that they can propose and convince Congress to fund.

Any honest read of this article will conclude that this very expensive rocket system is an absurd waste of money. It has no mission now, and will never get one considering the cost. Instead, NASA will spend billions to fly two test flights, both unmanned, and then the money will run out.

Scientists baffled by unknown source of CFCs

1:10 pm

The uncertainty of science: Scientists have found that, despite their complete ban since 2007, one type of ozone-depleting CFCs are still being pumped into the atmosphere from some unknown source.

Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to the ozone hole over Antarctica. Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012.

However, the new research shows worldwide emissions of CCl4 average 39 kilotons (about 43,000 U.S. tons) per year, approximately 30 percent of peak emissions prior to the international treaty going into effect. “We are not supposed to be seeing this at all,” said Qing Liang, an atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study published online in the Aug. 18 issue of Geophysical Research Letters, a journal of the American Geophysical Union. “It is now apparent there are either unidentified industrial leakages, large emissions from contaminated sites, or unknown CCl4 sources.”

That there seems to be an unknown source of CFCs suggests strongly that the entire theory of CFCs destroying the ozone layer is faulty. If CFCs were being produced naturally in the past then the ozone layer should not exist based on this theory. That it does exist says the CFCs are not harmful to it and were banned unnecessarily.

German journalists arrested by police in Ferguson

1:43 am

Modern American free speech: Two German journalists were arrested by police in Ferguson for wanting to take photographs of a burned out gas station.

The comments of one of the journalists was especially shameful:

This was a very new experience. I’ve been in several conflict zones: I was in the civil war regions in Georgia, the Gaza strip, illegally visited the Kaliningrad region when travel to the Soviet Union was still strictly prohibited for westerners, I’ve been in Iraq, Vietnam and in China, I’ve met Cuba dissidents. But to be arrested and yelled at and be rudely treated by police? For that I had to travel to Ferguson and St. Louis in the United States of America.

Except for the arrests of journalists there, I have not posted much about the situation in Ferguson, mostly because no one at present really knows what happened and the subsequent behavior of everyone has been exceedingly disgusting and uncivilized, undeserving to my mind of much attention.
