North Korea says it has authorized plans for nuclear strikes against the United States.
Bad: North Korea says it has authorized plans for a nuclear strike against the United States.
But, while Pyongyang has successfully carried out test nuclear detonations, most experts think it is not yet capable of mounting a device on a ballistic missile capable of striking US bases or territory. Mounting tension in the region could however trigger incidents on the tense and heavily-militarised border between North and South Korea. There was no immediate American reaction to the North’s latest statement, but US Defense Secretary Chuck Hagel said Pyongyang represented a “real and clear danger” to the United States and to its allies South Korea and Japan. [emphasis mine]
Right now North Korea almost certainly cannot hit the U.S. with an ICBM. However, South Korea and Japan are very very very exposed.

“The SLS program should be canceled now to free up approximately $10 billion programmed for this decade.”
I’m both glad and not surprised that some heavy hitters are beginning to say this. As I noted last year, as the commercial space program begins to show success the politics will increasingly favor it over the very expensive and not very productive NASA-built Space Launch System.
Be prepared for SLS to steadily lose political support in the coming years.

North Korea on Wednesday closed access to the Kaesong Industrial Park, a joint factory zone with South Korea.
Bad news: North Korea on Wednesday closed access to the Kaesong Industrial Park, a joint factory zone with South Korea.
Experts on the Korean situation had noted that we shouldn’t take seriously the harsh language coming out of North Korea as long as Kaesong was in operation. Thus, this news is very bad indeed.

An audit of California’s fiscal state has found it to be $127 billion in the red.
The day of reckoning looms: An audit of California’s fiscal state has found it to be $127 billion in the red.
Were California’s state government a business, it would be a candidate for insolvency with a negative net worth of $127.2 billion, according to an annual financial report issued by State Auditor Elaine Howle and the Bureau of State Audits. The report, which covers the fiscal year ending June 30, 2012, says that the state’s negative status — all of its assets minus all of its liabilities — increased that year, largely because it spent more than it received in revenue. [emphasis mine]
None of this is a surprise. California voters chose Jerry Brown and the Democrats to lead them into more debt.

Astronomers watch the central supermassive black hole of a galaxy eat something, either a planet or a brown dwarf.
Astronomers watch the central supermassive black hole of a galaxy eat something, either a planet or a brown dwarf.
Astronomers were using Integral to study a different galaxy when they noticed a bright X-ray flare coming from another location in the same wide field-of-view. Using XMM-Newton, the origin was confirmed as NGC 4845, a galaxy never before detected at high energies. Along with Swift and MAXI, the emission was traced from its maximum in January 2011, when the galaxy brightened by a factor of a thousand, and then as it subsided over the course of the year. “The observation was completely unexpected, from a galaxy that has been quiet for at least 20–30 years,” says Marek Nikolajuk of the University of Bialystok, Poland, lead author of the paper in Astronomy & Astrophysics.
By analysing the characteristics of the flare, the astronomers could determine that the emission came from a halo of material around the galaxy’s central black hole as it tore apart and fed on an object of 14–30 Jupiter masses. This size range corresponds to brown dwarfs, substellar objects that are not massive enough to fuse hydrogen in their core and ignite as stars. However, the authors note that it could have had an even lower mass, just a few times that of Jupiter, placing it in the range of gas-giant planets.
All the instruments listed above are orbiting space telescopes. You can read the science paper here.

James Hansen is retiring from NASA and will dedicate his time to global warming activism.
All that is really changing is that Hansen will no longer work for the government. The activism has been going on for a very long time.
Also, it is interesting how this New York Times article seems very unaware of this fact, which makes all of Hansen’s global warming claims very suspect. Might the Times not want the public to know this annoying detail?

At a cave rescue course
Posting this weekend is light because I am attending a class here in Tucson on cave rescue. Today, Saturday, was a mostly in class session going over the basics, most of which I am very familiar with from many years of experience. We did spend ninety minutes learning how to carry people around in a sked or sled, two different types of equipment used to carry a patient through difficult cave passage. In this case the terrain was simulated by going up, over, under, and around scaffolding and vehicles inside a garage. Lots of fun.
On Sunday we will be doing a mock rescue, whereby we will arrive at a cave entrance where we will have to locate the patient in the cave and get that person out of the cave safely. Should be most interesting.

The collapse of household income since 2009.
A comparison of the graph in the article above with the changing federal debt (both graphs below the fold) is quite revealing. The steep drop in household income in 2009 lines up precisely with the steep rise in federal deficits beginning in 2009. I wonder if they have anything to do with each other? The article also notes the possible negative impact of Obamacare. How could they think such a thing?

“We’re just not interested in continuing to support bureaucracies and talkfests.”
Canada to the UN environmental movement: “We’re just not interested in continuing to support bureaucracies and talkfests.”
The country has pulled out of a UN program supposedly aimed at “combating desertification,” noting that
only 18% of the roughly CAD$350,000 per year that Canada contributed to the U.N. initiative is “actually spent on programming,” [Canadian prime minister Stephen Harper] told Parliament this week during question period. “The rest goes to various bureaucratic measures. … It’s not an effective way to spend taxpayers’ money.”
As is their normal approach to debate, there is a lot of wailing, gnashing of teeth, and name-calling among the environmentalists, but no substantive response to counter Harper’s point above.

[W]e do have one pretty good metric with which to judge the country’s intentions: the Kaesong Industrial Complex. The Kaesong Industrial Complex, located just across the northern side of the border, is staffed by South and North Koreans. It can’t function without Pyongyang’s daily okay. If the North suddenly shuts down Kaesong at some point, watch out. But as long as it’s still running, as it has been throughout the provocations and tensions of the last few weeks, we can probably – probably — assume that North Korea is not actually planning to launch a war.
And the complex is still in operation.

Previous launches of the GSLV rocket used a Russian-built engine on a second stage. They also ended in failure, not because of the Russian equipment but because of other problems.

The competition heats up: Elon Musk confirms that on future Falcon 9 launches they will do tests of a powered return of the first stage.
For the upcoming flight, after stage separation the first stage booster will do a burn to slow it down and then a second burn just before it reaches the water. In subsequent flights they will continue these over-water tests. He repeatedly emphasized that he expects several failures before they learn how to do it right. If all goes well with the over-water tests, they will fly back to launch site and land propulsively. He expects this could happen by mid-2014.
These tests are an extension of the Grasshopper tests, only this time they will take place during an actual launch.
