The Met Office in the UK has issued an updated temperature record for the past 150 years, suggesting that the climate has warmed 0.75 degrees Celsius since 1900.

I remain suspicious of this announcement, as the scientists issuing this report are the same scientists who participated in climategate, including Phil Jones of the Climate Research Unit of East Anglia University. With that in mind, before I will believe these numbers I will wait for some vetting of this new data by those who have shown themselves to be a bit more skeptical, a bit more open-minded, and a lot more honest.

One more point: to really understand the importance of an increase of 0.75 degrees Celsius over 112 years, we would need some context, something this news article does not give us. For example, how do these numbers compare with the numbers predicted by the various climate models? Also, this is the overall change. How have things changed from year to year? Is there any evidence in this data for a cooling during the past decade, as indicated by other climate measurements?

Scientists have published the first complete global geological map of the Jupiter moon Io.

11:22 am

Scientists have published the first complete global geological map of the Jupiter moon Io.

The highly detailed, colorful map reveals a number of volcanic features, including: paterae (caldera-like depressions), lava flow fields, tholi (volcanic domes), and plume deposits, in various shapes, sizes and colors, as well as high mountains and large expanses of sulfur- and sulfur dioxide-rich plains. The mapping identified 425 paterae, or individual volcanic centers. One feature you will not see on the geologic map is impact craters. “Io has no impact craters; it is the only object in the Solar System where we have not seen any impact craters, testifying to Io’s very active volcanic resurfacing,” says Williams.

If there is water ice on the Moon, scientists have found that the bombardment from interstellar cosmic rays has likely caused chemical reactions that “can create complex carbon chains similar to those that help form the foundations of biological structures.”

Life stranger than science fiction: If there is water ice on the Moon, scientists have found that the bombardment from interstellar cosmic rays has likely caused chemical reactions that “can create complex carbon chains similar to those that help form the foundations of biological structures.”

A business in Missouri has become the first secular and private company to bring a lawsuit challenging the Obama administration’s contraception mandate.

Bring it on! A business in Missouri has become the first secular and private company to bring a lawsuit challenging the Obama administration’s contraception mandate.

Most of the discussion about the Obama administration’s mandate has revolved around whether specific religious organizations, such as the Catholic Church, should be exempted from it. To me, that misses the point. In a free society, anyone who objects to this mandate on the basis of personal belief should have the freedom to ignore it. Or to put it another way, the government has no right to order free citizens to buy contraceptives for others.

The TSA at work

9:19 pm

The TSA at work.

A toddler in a wheelchair is stopped by the TSA at ORD (O’Hare Airport in Chicago) and forced to into a sequestered area. On his way to a family vacation in Disney, this 3 year old boy is in a body cast for a broken leg. Despite assurances from his father that “everything is ok”, he is physically trembling with fear while he watches his two siblings, mother, father, grandfather and grandmother pass through along with everyone else…only to be singled out.

Here’s the video. You decide whether this makes any sense in the real world.

A private company has proposed salvaging a stranded communications satellite and use it to provide communications to Antarctica.

A private company has proposed a way to salvage a stranded communications satellite and use it to provide communications to Antarctica.

Now stranded in an elliptical orbit at an inclination of 51 deg., the spacecraft lacks enough fuel to reach its planned geostationary slot at 80 deg. E. Long. But there is enough fuel on board for it to function for as long as 10 years in a new orbit designed to keep it in sight of Antarctica for 14-16 hr./day, according to William Readdy, a co-founder of Polar Broadband Systems Ltd. Set up on the Isle of Man for the “once-in-a-lifetime opportunity” of salvaging the satellite, Polar Broadband has worked out a way to maneuver Express-AM4 into a 24-hr. elliptical orbit that will remain clear of the crowded geostationary belt for safety.

The FAA has issued a draft environmental impact statement required before the agency will allow SpaceShipTwo to be launched from the Mohave Air and Space Port.

Isn’t it nice to live in a free country? The FAA has issued a draft environmental impact statement, required before the agency will allow SpaceShipTwo to be launched from the Mohave Air and Space Port.

If the Wright Brothers had had to jump through the modern bureaucratic hoops required by today’s federal government, they probably wouldn’t have gotten their airplane off the ground until after World War I.

Aviation Week looks at the launch challenges facing SpaceX over the next two years.

Aviation Week looks at the launch challenges facing SpaceX over the next two years.

Though it is very clear SpaceX has a tough schedule of launches coming up, with much of the future of American aerospace riding on their success, this article is strangely hostile to the company. There is no doubt the company has fallen behind schedule, but the list of customers who have been willing to commit to the company is quite impressive, especially considering that SpaceX literally didn’t exist six years ago.

I’ll make several predictions:

  • SpaceX will experience further launch delays.
  • SpaceX will even have one launch failure in the next two years.
  • SpaceX will nonetheless succeed, because its successes will far exceed the failures, and they are clearly offering a better product for less money.

Russia has been forced to extend the application period for those who wish to become cosmonauts due to of a lack of response.

Only 151 applicants responded to this first-ever open astronaut application process in Russia’s history. This contrasts badly with NASA’s recent application call, which received the second highest response ever, 6372 applicants.

Environmentalist organizations have once again petitioned the EPA to ban ammunition using lead.

Environmentalist organizations have once again petitioned the EPA to ban ammunition using lead.

The ban sought by environmental groups would not apply to ammunition used by law enforcement and the military. In addition to bullets and pellets used in hunting and recreational activity like range shooting, the petition seeks to limit the use of the metal in fishing tackle and weights.

Government agencies get a pass, but not private gun ranges, eh? These petty dictators have really only one goal, and it has nothing to do with protecting wildlife. They want to prevent private citizens from having access to ammunition, which in turn will prevent them from having access to guns.

Two Sandia National Laboratories researchers are seeking a partnership with a private company to make and sell the self-guided bullet they developed.

8:29 pm

Investment opportunity: Two Sandia National Laboratories researchers are seeking a partnership with a private company to market the self-guided bullet they developed.

The prototype design is a four-inch long bullet with a built-in optical sensor in its nose to detect a laser beam on the target. The sensor directs guidance and control information using an algorithm and a small central processing unit that helps steer tiny built-in fins to guide the bullet. According to the Sandia lab’s computer simulations, an unguided bullet in real world conditions can miss a target that is half a mile away by almost 10 yards. With this guided bullet, however, it could strike within eight inches of a target.

Austrian skydiver Felix Baumgartner, aiming to complete a record-setting 120,000 foot dive from edge of space, successfully completed a 71,581 foot practice dive today.

7:47 pm

Austrian skydiver Felix Baumgartner, aiming to complete a record-setting 120,000 foot dive from edge of space, successfully completed a 71,581 foot practice dive today.

From launch to touchdown, the entire test flight lasted just over eight minutes, officials said. According to Baumgartner, the toughest part of the leap was the extreme cold he experienced high up in Earth’s atmosphere. “I could hardly move my hands,” the skydiver said in a statement. “We’re going to have to do some work on that aspect.”

Baumgartner is gearing up for an even bigger leap — his so-called “space jump” — from 120,000 feet (36,576 m) this summer. The current record for highest-altitude skydive is 102,800 feet (31,333 m), set in 1960 by U.S. Air Force Captain Joe Kittinger.

The orbit of a 150 foot wide asteroid that zipped past the Earth in February, has an orbit so much like the Earth’s that astronomer’s expect it back next year.

7:42 pm

Duck! The orbit of a 150 foot wide asteroid that zipped past the Earth in February, has an orbit that will bring it past the Earth again on February 15, 2013 by less than 15,000 miles.

The team use several automated telescopes to scan the sky, and the discovery came somewhat serendipitously after they decided to search areas of the sky where asteroids are not usually seen. “A preliminary orbit calculation shows that 2012 DA14 has a very Earth-like orbit with a period of 366.24 days, just one more day than our terrestrial year, and it ‘jumps’ inside and outside of the path of Earth two times per year,” says Jaime.

While an impact with Earth has been ruled out on the asteroid’s next visit, astronomers will use that close approach for more studies and calculate the Earth and Moon’s gravitational effects on it.

Because this newly discovered asteroid passes so close and frequently to both the Earth and Moon, astronomers will need a lot more data before they can pin down its orbit precisely, and thus predict the chances of a collision in the near future.

Have researchers found Leonardo da Vinci’s lost “The Battle of Anghiari” fresco, hidden for the past six centuries behind a wall?

Have researchers found Leonardo da Vinca’s lost “The Battle of Anghiari” fresco, hidden for the past six centuries behind a wall?

The painting, considered a masterpiece by contemporaries, had never been finished by da Vinci because he had used an experimental technique to paint it, and that technique had failed. Thus, the painting was painted over fifty years later. The only reason we have a good idea of what the painting looked like is that several artists were so impressed by it that they produced copies while it was still visible.

The research suggests the painting was not painted over, but that a false wall was built in front of it. If so, this would be truly exciting discovery. The painting would probably not be in very good shape, but to actually see it would be wonderful.

The three big network nightly news shows all failed to mention the Congressional Budget Office report that says the cost of Obamacare will be twice what was predicted, and that millions will lose their healthplans because of it.

News you can’t use: All three network nightly news shows last night failed to mention the Congressional Budget Office report that says the cost of Obamacare will be twice what was predicted, and that millions will lose their health plans because of it.

This is a good example of why I’ve said for years that if you depend on television for your news, you are not only uninformed, you are misinformed.

It appears that the reason the head of Russia’s space agency was hospitalized last week was because he got into a fight at a party over a woman.

10:34 am

You can’t make this stuff up: It appears that the reason Vladimir Popovkin, the head of Russia’s space agency, was hospitalized last week was because he got into a fight at a party over a woman.

The woman in question was apparently General Popovkin’s press secretary, Anna Vedischeva, 28. Vedischeva was appointed despite criticism when it was revealed that she was an ex-glamour model who, by her own admission, knew nothing about space or public relations. The party where the incident allegedly took place was to celebrate International Woman’s Day on 8 March.

The judge in the JPL intelligent design lawsuit has ruled against JPL. The press will be allowed to observe and report on the testimony.

David Coppedge, the man JPL fired, testified yesterday, outlining his belief in intelligent design. From the quotes included in the article, he certainly didn’t put forth a convincing case. He also didn’t say anything that justified firing him.
