Orbital Sciences, having delayed the launch of its first operational Cygnus cargo mission to ISS by one day, has named the spacecraft after the late astronaut Gordon Fullerton.
Today NOAA posted its monthly update of the solar cycle, showing the sunspot activity for the Sun in November. As I do every month, I am posting it here, below the fold, with annotations.
As in October, the Sun was more active than it has been for this entire solar maximum. November’s numbers dropped slightly from October, but still remained high, though as has been typical for this solar maximum they remained below prediction.

Scientists have published the first 300 days of radiation data from Curiosity on Mars.
The results suggest that while the radiation on Mars requires some shielding, most of the worst radiation a traveler would be exposed to would occur during the journey in space to and from Earth. The graph below illustrates this.
Curiosity has succeeded in dating the age of one of its rock samples, the first time this has ever been done remotely on another planet.
The second rock Curiosity drilled for a sample on Mars, which scientists nicknamed “Cumberland,” is the first ever to be dated from an analysis of its mineral ingredients while it sits on another planet. A report by Kenneth Farley of the California Institute of Technology in Pasadena, and co-authors, estimates the age of Cumberland at 3.86 billion to 4.56 billion years old. This is in the range of earlier estimates for rocks in Gale Crater, where Curiosity is working.
This is significant engineering and scientific news. In the past the only way to date the rocks on another world was to bring them back to Earth. This was how the moon’s geology was dated. On Mars, dating has only been done by crater counting, comparing those counts with those on the Moon, and then making a vague guess. To have the ability to date rocks remotely means that geologists can begin to sort out the timeline of Mars’s geology without having to bring back samples.
Apropos my comment here, Rand Simberg superbly summarizes the serious threat SpaceX poses for the older space launch companies.
Yesterday police in Wisconsin celebrated Pearl Harbor Day by issuing tickets to people waving the American flag.
Video below the fold. Stick around to the end. As the man says, “The cops can’t scare us off, can they?”

Does this make you feel safer? Of the 78 times police in Greensboro, North Carolina, fired their pistols in 2012, all but two were to kill someone’s pet.
Don’t you feel safer? A TSA agent confiscates the two-inch fake pistol of a monkey sock puppet.
Another news report suggests that Republicans are preparing to surrender in budget talks.
Senior aides familiar with the talks say the emerging agreement aims to partially repeal the sequester and raise agency spending to roughly $1.015 trillion in fiscal 2014 and 2015. That would bring agency budgets up to the target already in place for fiscal 2016. To cover the cost, Ryan and Murray are haggling over roughly $65 billion in alternative policies, including cuts to federal worker pensions and higher security fees for the nation’s airline passengers.
Republican leaders are also seeking additional savings to knock a small dent in deficits projected to exceed $6 trillion over the next decade. But the deal would do nothing to trim the debt, which is now larger, as a percentage of the economy, than at any point in U.S. history except during World War II. [emphasis mine]
To me, the biggest disappointment of this surrender is that Paul Ryan is negotiating it, proof that he too is no fiscal conservative and worse is far more stupid than I had thought.
No, you can’t keep your medicines either under Obamacare.
The article is long and detailed. It seems a lot of expensive but life-saving drugs might be excluded from many plans because of cost. Worse,
The biggest problem in all of this is that consumers will have a very hard time figuring out where they stand. In many cases, the health plans being offered in the Obamacare exchanges don’t make information about their drug formularies readily available. In some cases, it doesn’t seem to be published anywhere.
The government was supposed to mandate that plans made this information easily accessible. But that never happened.
In fact, state and federal regulators must have approved the health plans without reviewing final drug formularies. Many plans are also not publishing information about their networks of doctors, or when they do; the information is unreliable (listing, for example, doctors who argue that they aren’t part of the plans).
Aren’t you glad those brave Democrats and President Obama shut the government down in October to prevent those evil Republicans from making any changes to Obamacare?
Using Solar Dynamics Observatory (SDO), scientists have finally identified the Sun’s predicted giant jet streams.
These large flows, bigger than any flow structures previously identified, might help explain the Sun’s rotation (which is faster at the equator than at the poles), its magnetic field, and its production of sunspots. Not surprisingly, however, the models and data do not match exactly:
Mark Miesch, a physicist at the National Center for Atmospheric Research in Boulder, Colorado, says the new study confirms modelling work he and others have done on giant convective cells4. There are, however, some differences between what the models suggest and what Hathaway’s team observed. For instance, the models indicate that giant cells should align themselves from north to south near the Sun’s equator, an arrangement that isn’t seen in the new data. In fact, points out solar physicist Junwei Zhao of Stanford University in California, most of the giant cells were seen at high latitudes, and they need to be spotted at lower latitudes as well. “Whether it will convince the community remains to be seen,” says Zhao.
The competition heats up: Russia’s deputy prime minister is pushing to accelerate the completion of Russia’s new spaceport in Vostochny.
The first scheduled launch is now planned for 2015, but this article suggests they are trying to make it happen by the fall of 2014.
