The science team for Cassini has released a spectacular mosiac of Saturn and its rings, backlit by the Sun.
NASA has named the impact site where the two GRAIL spacecraft hit the Moon today after American astronaut Sally Ride.
Though this is a nice gesture, the entire public relations campaign surrounding the GRAIL impact today has been one of the more overhyped exercises at NASA. The impact is going to provide very little new science, and is necessary because no lunar orbit is stable and the spacecraft will eventually crash into the Moon anyway. Better to do it under controlled circumstances. To make such a big deal about it however is hardly interesting, especially since this has been done repeatedly by practically every lunar orbiter.
A preliminary copy of the next IPCC report has been leaked.
In the coming days there will be much discussion of this document — such as how it appears the IPCC has finally acknowledged the importance of the Sun’s variability to climate change — but for now, I post on the right what is probably its most important admission. This graph from the leaked report shows the rise in global temperatures as predicted by all the different climate models used by the IPCC, compared to actual observed temperatures. As you can see, since the late 1990s there has been no significant increase in global temperature. Moreover, the observed data now sits outside the predicted margin of error for all the models, making every single one of these models completely wrong.
But don’t worry, these facts aren’t important. In fact, any facts that contradict the religion of global warming must be ignored. It is far more important to shut down all industry and live like cavemen, just because we have faith in our belief in global warming.
An attempt to drill down into another buried lake in Antarctica, this time by Great Britain, has encountered serious technical problems because of a failed boiler.
China’s Chang’e 2 lunar probe, now out of lunar orbit, did a fly-by of the 3 mile wide asteroid Toutatis as it zipped past the Earth last week, resulting in some spectacular images.
Launched on October 1, 2010, Chang’e 2 orbited the Moon for 8 months before being redirected last year to the L2 Lagrange point, roughly a million miles on the side of Earth opposite the Sun. But when it left L2 last April, Western observers suspected the spacecraft was heading deeper interplanetary space. It didn’t take long to realize that Chang’e 2 was bound for Toutatis.
This is an example of a very smart re-use of a space probe.
By the way, the first fly-by of another planet took place fifty years ago this week.
Good news: Climate experts are now calling for an end to the regularly scheduled mega-climate summits.
That these summits haven’t accomplished anything but allow climate bureaucrats to burn tons of airplane fossil fuel to gather in some of the world’s nicest warm weather cities during the winter — thereby making them all look like hypocrites — is not the reason these experts want to cancel the summits. They want to cancel the summits because the summits aren’t getting them the results they want: strict regulation on the lives of everyone else.
Nowhere does the article address the simple fact that in the past three years, since the release of the climategate emails, the creditability of the entire climate change field has gone to zero. The public doesn’t buy their sales pitch anymore, and thus neither do politicians, which is why no one is willing to make a deal at these summits. No one believes anything these climate experts are saying, especially since they have refused to clean up the corruption within their field.
The nine most important archeological and paleontological discoveries in 2012.
I especially like #8, since it involves an actual person.
Watch a three mile wide asteroid fly past the Earth – live tonight from 5 to 11 pm (Eastern)!
Today, with little fanfare, the solar scientists at the Marshall Space Flight Center adjusted slightly downward their prediction for the upcoming solar maximum, from a sunspot number of 73 down to 72. This was the fourth month in a row that they have revised their prediction.
The Marshall scientists do not archive their predictions, which I suspect is a convenient way of preventing people from noticing how much they change them. I however like to archive these revisions. Below is a full list of their changes during the past two years:

The uncertainty of science: Climate models still fail to predict mid- and long-term trends in the climate.
To test the forecast quality of the 23 most important climate models, the AWI scientists investigated how well these models were able to reproduce atmospheric teleconnection patterns over the past 50 years. A total of 9 known circulation patterns were investigated retrospectively, four of which in special detail. The result was that the spatial distribution of atmospheric teleconnection patterns is already described very well by some models. However, none of the models were able to reliably reproduce how strong or weak the Icelandic Low, Azores High and other meteorological centers of action were at a particular time over the last 50 years, i.e. the temporal distribution patterns. [emphasis mine]
The “centers of action” are large global weather patterns like el Nino that can influence the global climate worldwide. Most climate scientists believe that global warming will manifest itself first in these centers of action. Yet, no climate model was able to predict what we know actually happened during the past fifty years with these large centers.
But we must ignore this fact and base all our climate law on what these models predict. What could go wrong?
In related news, the United Kingdom had its coldest autumn since 1993 this year. And if you look at the temperature graph at the link, covering autumn temperatures since 1910, you will notice hardly any change, up or down.
The uncertainty of science: A look at some modern animals, drawn with the same limited fossil record we have for the dinosaurs.
In other words, almost everything we assume about the dinosaurs is probably wrong.
A tour of the impact craters that Curiosity created when it landed on Mars.
O goody: The GAO is concerned about the future budget and schedule of the James Webb Space Telescope.
This is very bad news if true for NASA’s astronomy program. Webb was originally budgeted at $1 billion and scheduled to launch in 2011. Its budget is now $8.8 billion and its launch is now set for October 2018. And until it launches there is little money to build any other space telescope.
NASA announced yesterday plans to launch by 2020 a twin rover of Curiosity to Mars.
Though it makes sense to use the same designs again, saving money, I must admit a personal lack of excitement about this announcement. First, I have doubts it will fly because of the federal government’s budget woes. Second, it is kind of a replacement for the much more challenging and exciting missions to Titan and Europa that the Obama administration killed when they slashed the planetary budget last year.
The big news is out. Today the eagerly awaited press conference at the American Geophysical Society meeting in San Francisco on the recent results from the Mars rover Curiosity was finally held. The announced results had been hyped like crazy when rumors began to spread a few weeks ago that Curiosity had discovered something truly spectacular.
Well, here are some of the headlines heralding the results.

New data suggests that the icy crust of Titan is twice as thick as previously estimated.
“The picture of Titan that we get has an icy, rocky core with a radius of a little over 2,000 kilometers, an ocean somewhere in the range of 225 to 300 kilometers thick and an ice layer that is 200 kilometers thick,” [said Howard Zebker of Stanford University]. Previous models of Titan’s structure estimated the icy crust to be approximately 100 kilometers thick.
This means that the methane lakes and rivers of Titan are flowing across a bedrock of ice, which at the cold temperatures there would be as solid as rock is here on Earth.
NOAA’S latest monthly update of the Sun’s ongoing ramp up to solar maximum has just been published and, as I do every month, I have posted the latest graph, with annotation, below the fold.
As the Sun had been somewhat active in November, I had expected the graph line to rise. It has, but not by very much.

Changes in the levels of sulphur dioxide (SO2) since Venus Express arrived in orbit around Venus in 2006 now suggest strongly that the spacecraft has detected volcanic activity on the planet.
The SPICAV data show that the concentration of SO2 above the main cloud deck increased slightly to about 1000 parts per billion by volume (ppbv) between 2006 and 2007, but then steadily decreased over the next five years, reaching only 100 ppbv by 2012. This is very reminiscent of a pattern observed by Pioneer Venus during the 1980s, the only other multi-year dataset of SO2 measurements.
One of best explanations for these changes is a volcanic eruption back in 2006, which would have inserted a great deal of SO2 into the upper atmosphere. Since then, ultraviolet radiation from the sun has steadily destroyed it.
Messenger has found new and “compelling” evidence that there is water ice locked in the permanently shadowed craters of Mercury.
On Monday I had spoken to one of the project scientists for this discovery, David Lawrence, in connection with an article I am doing for Astronomy on the evidence of water on the Moon. I knew the Mercury announcement was coming, and asked him for some details. Based on what he told me, it struck me that the evidence for water on Mercury is actually more conclusive than the evidence for the Moon. (In fact, inconclusive nature of the lunar data is the point of my Astronomy article, based on previous posts here and here on Behind The Black.
The more intriguing aspect of this discovery on Mercury, however, is the unknown dark material that covers and protects some of this water ice. That some scientists believe it might even be organic material deposited there by comets and asteroids is most interesting.
Two stories today illustrate the levels of corruption that now percolate through many fields of science, helped by a willing and sometimes ignorant press.
First, a final report has been issued in the investigation into the fraudulent research of social psychologist Diederik Stapel. Sadly, it appears the report condemns the entire field:

Cassini has taken some spectacular new images of the gigantic hexagon-shaped vortex on Saturn’s north pole.
The biggest black hole yet found, 17 billion times the mass of our sun.
The unusual black hole makes up 14 percent of its galaxy’s mass, rather than the usual 0.1 percent. … NGC 1277 [the galaxy] lies 220 million light-years away in the constellation Perseus. The galaxy is only ten percent the size and mass of our own Milky Way. Despite NGC 1277’s diminutive size, the black hole at its heart is more than 11 times as wide as Neptune’s orbit around the Sun.
Based on these measurements, it appears that this black hole is literally eating this galaxy whole.
NASA is soliciting ideas on how to use the two Cold War era telescopes given to the space agency by the military.
Both telescopes are comparable in size to the Hubble Space Telescope.
Impressive radar images of near-Earth asteroid 2007 PA8 were taken during its recent fly-by of Earth.
The images … reveal possible craters, boulders, an irregular, asymmetric shape, and very slow rotation. The asteroid measures approximately one mile wide (about 1.6 kilometers).
The asteroid poses no threat to Earth. The resolution of the images, however, is astonishing, especially considering it was done by radar.
