Scientists now believe they have found evidence proving that the unknown origin of cosmic rays are supernova explosions.
This has been one of astronomy’s longest outstanding mysteries: What produces the interstellar cosmic rays that come from outside our solar system?
The next flight of Dragon to ISS has been set for March 1.
Asteroid 2012 DA14 might experience seismic activity, an asteroid quake, when it zips pass the Earth tomorrow.
[MIT scientist Richard] Binzel imagines what an astronaut floating alongside such an asteroid might see: “The surface could slowly sway or rock by a few centimeters. Other things to look for would be puffs of asteroid-dust rising from the surface and gentle avalanches on the steepest slopes of craters.” In rare cases, “rubble pile” asteroids might break apart during the encounter and then re-form as Earth recedes into the distance.
William Shatner proposes naming Pluto’s two unnamed moons Romulus and Vulcan.
Astronomers running the Pluto moon naming campaign accepted Vulcan, adding it to the list a day after Shatner suggested it, but Romulus didn’t make the cut. “Mr. Shatner’s second suggestion, Romulus, has a bit of a problem because it is already the name of a moon,” Mark Showalter, an astronomer involved with the competition, wrote in a blog on the Pluto Rocks website on Tuesday. “Romulus, along with his brother Remus, are the names of the moons of the asteroid 87 Silvia. They were discovered by a team led by my good colleague Franck Marchis, now a senior scientist at the SETI Institute.”
One of the plaques inside the Peace Forest
Just after the 1967 war, a strip of land in Jerusalem that had been part of no man’s land after the city was divided following the 1948 war was turned into a Peace Forest to symbolize “the hope for peace and serenity between all Jerusalem’s residents.” Located on a hillside that overlooks the city, the Jewish National Fund sponsored a campaign to have the site landscaped elegantly, with a promenade and a series of architectural observation points, each designed differently as if their architects were competing with each other for the most creative structure.
In 2003 my oldest nephew was married from the highest point on this hillside, just above the Peace Forest, with the entire city of Jerusalem as the backdrop. At the time there was a catering hall at this location, and it seemed to them to be a perfect place to tie the knot.

Chicken Little report: A 150 foot wide asteroid will buzz the Earth tomorrow at a distance of only 17,000 miles.
There have been numerous news articles about this fly-by for the last two weeks, all hyping the dangers of an impact that in this case simply won’t happen. A threat of an impact from an asteroid is real and should be dealt with, but the reporting here has at times been somewhat silly. Asteroid 2012 DA14 is not going to hit us as it goes by. All that will happen is that scientists will have take advantage of this opportunity to look at it.
The hot fire test of the Antares first stage tonight was aborted at the last second.
The planned first stage propulsion system “hot fire” test of Orbital’s new Antares medium-class rocket was halted in the final seconds of the countdown by the rocket’s flight computer, which detected an anomalous condition. The Antares team will evaluate the data from the test to determine the nature of the abort. A new date for the test has not been determined.
With any new rocket this kind of thing is to be expected. The concern here is the tight schedule that Orbital Sciences is under to get Antares and Cygnus operational. Long delays will not be good for them, considering the politics in Congress. Every delay will be used by certain politicians to get this program cut so the money can go to the very expensive Space Launch System that feeds the jobs in their districts.
Update: It appears the issue was that the computer detected a low pressure reading and aborted the burn. (A similar issue occurred on several of SpaceX’s early launches as was very quickly corrected.) A rescheduled hot burn is expected to take place next week.
An evening pause: Liz Callaway performs the public debut of a magnificent song from her album “Passage of Time.” If you want to hear how it sounds on the album, go here.
If it’s the government it’s okay to steal your property.
The hot fire test of the first stage of the Antares rocket has been rescheduled to tonight.
No reason has been given for the one day delay.
Among cavers there is a saying: “The most dangerous part of any cave trip is the drive to and from the cave.” Well, that might just apply to trips to Israel. On my last flight home on Thursday there was a woman sitting behind me wearing a face mask, the kind used to protect the wearer from other people’s germs. In her case, however, it was to protect everyone else. During the whole flight to Phoenix she coughed continually.
On Friday night my throat felt scratchy. By Sunday it was clear that I had caught a bad cold. Today is day five, which is usually the worst. I had intended to write up my last report about my trip to Israel but I just don’t have the energy. The best I can do today is post some news items, do some easy reading for another Astronomy article I’m writing, and tape an appearance tonight on the John Batchelor Show. The longer essay will have to wait until tomorrow.
Update: Just for your added pleasure, the image below the fold shows the view of Bethlehem from the main highway south out of Jerusalem. The tunnel and high security fence were installed after the most recent intifada. Before then you had to drive through town, which was slow, but also dangerous as Bethlehem is controlled by the Palestinian Authority. During the intifada the danger became acute as commuters would have rocks thrown at them, and some were even shot at. The security fence, condemned by all the world, was an attempt to protect commuters from this threat.

Some details have been released about that deal between Russia and Kazakhstan over the Baikonur spaceport.
It seems the conflict does revolve around Russia’s new spaceport under construction in Vostochny, and how it might compete with Baikonur. Kazakhstan feels threatened, and is trying to forestall a loss in business.
Pushback: A boycott by firearms companies against states that pass gun control laws appears to be growing.
Russian investigators, having pinpointed the cause of a December 2012 launch failure, have cleared the Proton rocket to resume commercial launches in March.
It is interesting that this failure of the Proton’s Briz-M upper stage was not related to two previous failures of that same upper stage. It is also interesting that the article does not describe what actions have been taken to correct the problem.
If I was a future Proton launch customer I would be very concerned. Three launch failures all related to the Briz-M upper stage, and all from different causes. This appears to suggest some fundamental problems with the stage itself, or with the company that manufactures it.
On a Tuesday drop test engineers successfully demonstrated that the Orion capsule could land safely if one of its three parachutes failed.
An evening pause: On Lincoln’s birthday, a tribute.
It is often claimed by those who oppose Israel that it is an apartheid state that imprisons its Arab population, both in Israel itself as well as in the West Bank and Gaza.
Like much that is said about Israel, however, this claim has little to do with reality, and in fact, as I said yesterday, turns reality on its head.
Inside Israel, Arabs have the option (though some have decided not to take it) of becoming full citizens. Thus, not only are Israeli Arabs among the most prosperous Arabs in the Middle East, they have more rights under the Israeli democratic government than most Arabs in every other Arab country. They can vote, and have even served as elected members of Parliament.
Compare that with the way Arabs treat their religious minorities. Jews are of course forbidden. Christians meanwhile are fleeing the Islamic Middle East because of its persecution of non-Muslims.

I wonder why: The newly released “ObamaCare Survival Guide” has rocketed to the No. 2 spot on The New York Times’ bestseller list for advice-giving paperbacks.
It is also No. 1 on many amazon.com lists. This quick demand only indicates once again how bad this law is, requiring people to desperately search for ways to deal with it. Sadly, its negative impact on business and healthcare in the coming years is going to continue.
Update: And in related news, Virginia’s state liquor organization is limiting the hours of all part-time workers to avoid the costs of Obamacare.
The day of reckoning looms: North Korea successfully set off an underground nuclear explosion today.
But don’t worry. The U.N. is going to talk about it later today. So will Obama.
