“Re-election is the farthest thing from my mind.”

12:44 am

We need more elected officials like this:

“Re-election is the farthest thing from my mind,” said Representative Tom Reed, a freshman Republican from upstate New York. “Like many of my colleagues in the freshman class, I came down here to get our fiscal house in order and take care of the threat to national security that we see in the federal debt. We came here not to have long careers. We came here to do something. We don’t care about re-election.”

Wither the Arctic Icecap?

12:03 am

In a paper published today in Geophysical Research Letters, climate scientists have estimated the distribution and trends for the Arctic icecap from 1980 through March 2011. What they have found is a significant decline in older ice on top of an overall declining trend that showed a strong but partial recovery since 2008. The graph below, from the paper, illustrates clearly these trends.

Arctic Ice, 1980 - 2011

What this means for the icecap itself remains unclear. As the scientists themselves note in their conclusion:

“Dominate. Intimidate. Control.”

8:05 pm

“Dominate. Intimidate. Control.”

Now, thanks to TSA Chief John Pistole’s determination to “take the TSA to the next level,” there will soon be no place safe from the TSA’s groping searches. Only this time, the “ritualized humiliation” is being meted out by the serpentine-labeled Visible Intermodal Prevention and Response (VIPR) task forces, comprised of federal air marshals, surface transportation security inspectors, transportation security officers, behavior detection officers and explosive detection canine teams. At a cost of $30 million in 2009, VIPR relies on 25 teams of agents, in addition to assistance from local law enforcement agencies as well as immigration agents. And as a sign of where things are headed, Pistole, himself a former FBI agent, wants to turn the TSA into a “national-security, counterterrorism organization, fully integrated into U.S. government efforts.” To accomplish this, Pistole has requested funding for an additional 12 teams for fiscal year 2012, bringing VIPR’s operating budget close to $110 million.

Environmental terrorists destroy genetically modified test plots of wheat and potatoes

2:23 pm

Leftwing civility: Environmental terrorists destroy genetically modified test plots of wheat and potatoes.

On the night of 9 July, half a dozen masked attackers overpowered the security guard watching over test fields in Gross Lüsewitz, near Rostock. They then destroyed a field of wheat resistant to fungal diseases and a field of potatoes engineered to produce cyanophycin, an amino acid polymer that could potentially be used to make plastics. . . . Two nights later, a dozen attackers threatened guards with pepper spray and bats at a demonstration garden in Üplingen, in the state of Saxony-Anhalt. They destroyed a field of potatoes and trampled wheat and maize.

Bad news for climate modelers

12:20 pm

A new analysis of the orbits of Ceres and Vesta says that in a surprisingly short time those orbits become chaotic and therefore unpredictable. More significantly, those orbits interact with the Earth’s and also make its long term orbit chaotic and unpredictable. From the abstract:

Although small, Ceres and Vesta gravitationally interact together and with the other planets of the Solar System. Because of these interactions, they are continuously pulled or pushed slightly out of their initial orbit. Calculations show that, after some time, these effects do not average out. Consequently, the bodies leave their initial orbits and, more importantly, their orbits are chaotic, meaning that we cannot predict their positions. The two bodies also have a significant probability of impacting each other, estimated at 0.2% per billion year. Last but not least, Ceres and Vesta gravitationally interact with the Earth, whose orbit also becomes unpredictable after only 60 million years. This means that the Earth’s eccentricity, which affects the large climatic variations on its surface, cannot be traced back more than 60 million years ago. This is indeed bad news for Paleoclimate studies. [emphasis mine]

The scientists found that it became impossible to calculate the orbits of the two largest asteroids after only several ten thousand years. They also found that “numerous asteroids in the main belt will behave in the same way with . . . much more chaotic behavior than previously thought.” Worse, the possibility of collisions was far higher than ever thought. Ceres and Vesta have a 1 in 500 chance of colliding with each other every billion years, while other asteroids have chances as low as 1 in 1000.

The importance of this discovery, which still needs to be confirmed by other researchers, cannot be understated.

Another fuzzy Dawn image?

12:11 pm

July 9 Vesta image

Another image of Vesta from Dawn has been released. This image was taken on July 9 from a distance of 26,000 miles away. It is definitely an improvement over the previous image, with more small details becoming visible. However, I once again wonder about the softness of the image. Look at the limb of the planet. It is soft against the black sky. This is not what one would expect from perfectly focused camera.

Dawn goes into orbit around Vesta next week. We sure learn then for sure if there is a problem with its camera, or whether I am merely being a bit too nervous.

Being tone deaf is not a good way to fund a government space program

11:59 am

Yesterday the House appropriations committee’s released budget numbers that included no additional funds for commercial space, limiting the subsidies to $312 million, the same number as last year and significantly less than the $850 million requested by the Obama administration.

This is what I have thought might happen since last year. The tone deaf manner in which the Obama administration has implemented the private space subsidies is leaving all funding for NASA vulnerable.

Astronomers have found two new brown dwarf stars only 15 and 18 light years away

11:08 am

Astronomers have found two new brown dwarf stars only 15 and 18 light years away.

Most brown dwarfs have reached surface temperatures below the “oven temperature” of about 500 Kelvin (about 230 degrees Celsius), may be even as cool as the temperature at the surface of the Earth. The search for these elusive neighbours of the Sun is currently in full swing. It cannot be excluded that ultracool brown dwarfs surround us in similar high numbers as stars and that our nearest known neighbour will soon be a brown dwarf rather than Proxima Centauri.

NASA stalls, Texas lawmakers fume

10:12 pm

The law is such an inconvenient thing: In a bipartisan effort, Texas lawmakers roast NASA administrator Charles Bolden for not meeting mandated Congressional deadlines for Congress’s personally designed rocket, the program-formerly-called-Constellation.

The heavy-lift rocket and capsule that Congress insists NASA build is a complete waste of money and nothing more than pork. It will never get built, mainly because Congress has given NASA less money and less time to build it than they did for Constellation under the Bush administration. Unfortunately, the reason they continue to require NASA to build it is to provide pork to their districts.

In a perfect world this funding would be cut now, especially considering the state of the federal debt.

Second ARTEMIS space probe about to enter lunar orbit

8:27 pm

The second ARTEMIS space probe will enter lunar orbit on Sunday.

“With two spacecraft orbiting in opposite directions, we can acquire a full 3-D view of the structure of the magnetic fields near the moon and on the lunar surface,” said Vassilis Angelopoulos, principal investigator for the THEMIS and ARTEMIS missions and a professor of space physics at UCLA. “ARTEMIS will be doing totally new science, as well as reusing existing spacecraft to save a lot of taxpayer money.”

White dwarf stars in a dance of death

8:24 pm

White dwarf stars in a dance of death.

[The binary pair of] white dwarfs are so near they make a complete orbit in just 13 minutes, but they are gradually slipping closer together. About 900,000 years from now – a blink of an eye in astronomical time – they will merge and possibly explode as a supernova. By watching the stars converge, scientists will test both Einstein’s general theory of relativity and the origin of some peculiar supernovae.

The two white dwarfs are circling at a bracing speed of 370 miles per second (600 km/s), or 180 times faster than the fastest jet on Earth. “I nearly fell out of my chair at the telescope when I saw one star change its speed by a staggering 750 miles per second in just a few minutes,” said Smithsonian astronomer Warren Brown, lead author of the paper reporting the find.

The brighter white dwarf contains about a quarter of the Sun’s mass compacted into a Neptune-sized ball, while its companion has more than half the mass of the Sun and is Earth-sized. A penny made of this white dwarf’s material would weigh about 1,000 pounds on Earth. Their mutual gravitational pull is so strong that it deforms the lower-mass star by three percent. If the Earth bulged by the same amount, we would have tides 120 miles high. [emphasis mine]
