This is the first time that a vehicle has made it into space and had all components fully recovered for reuse since the NASA flights of the X-15 in the 1960s.

Geoffrey.landis writes: Computerized voting machines are bad news in general, but the WINVote machines used in Virginia might just have earned their reputation as the most insecure voting machine in America, featuring wifi that can't be turned off (protected, however, with a WEP password of "abcde"), an unencrypted database, and administrative access with a hardcoded password of "admin." According to security research Jeremy Epstein, if the machines weren't hacked in past elections, "it was because nobody tried." But with no paper trail-- we'll never know.
Well, after ignoring the well-documented problems for over a decade, Virginia finally decided to decommission the machines... after the governor had problems with the machines last election and demanded an investigation.
"In total, the vulnerabilities investigators found were so severe and so trivial to exploit, Epstein noted that “anyone with even a modicum of training could have succeeded” in hacking them. An attacker wouldn’t have needed to be inside a polling place either to subvert an election... someone 'within a half mile with a rudimentary antenna built using a Pringles can could also have attacked them."
According to the Washington Post
"The voting machines that Sedgwick County uses have a paper record of the votes, known as Real Time Voting Machine Paper Tapes... . Since the software is proprietary, even elections officials can’t examine it and postelection audits can’t be done, according to Pamela Smith, president of Verified Voting Foundation".
Even the Kansas papers editorialize that this is going too far. More evidence that the software used in voting machines should never be proprietary.
Geoffrey.landis writes: Last week a news story suggested that a new model of sunspot activity predicted a dramatic drop in solar activity coming up, possibly resulting in coming a mini-ice age. Take that prediction with a bit of skepticism, though-- later news analysis suggests that the story may be more media hype than science. Valentina Zharkova, the scientist whose research is being quoted, made no mention of a "mini Ice age"-- her work was only on modelling the solar dynamo. And, in any case, the solar minimum predicted was estimated to last only three solar cycles-- far less than the 17th century Maunder Minimum.

The complex, dynamic nature of our atmosphere and oceans makes it extremely difficult to link any particular weather event to climate change. That’s because of the intermingling of natural variations with human-caused ones. http://fivethirtyeight.com/fea...
They also cite a Nature editorial pointing out the same thing about extreme weather: http://www.nature.com/news/ext...

Less well recognized is the disparity in station crews. Before the shuttle stopped flying, an equal number of American and Russian crew members lived on board. But afterwards the bear began squeezing. For every two NASA astronauts that have flown to the station, three Russians have gone.

So, for your entertainment, here's my comet ISON playlist. Comments?
Geoffrey.landis writes: "The historical period that we call the dark ages, from perhaps 600 to 1200 AD, was the golden age of Islamic science, when great advances in science and technology were taking place in the middle east. But somehow, as the west experienced its renaissance, the blossoming of the age of science, and the founding of the modern technological world, the Arabic world instead turned away from science. Muslim countries have nine scientists, engineers, and technicians per thousand people, compared with a world average of forty-one, and of roughly 1.6 billion Muslims in the world, only two scientists from Muslim countries have won Nobel Prizes in science.
Why? In an article "Why the Arabic World Turned Away from Science" in The New Atlantis, Hillel Ofek examines both the reasons why Islamic science flourished, and why it failed.
Are we turning the same way, with a rising tide of religious fundamentalism and dogma shouting down the culture of inquiry and free thinking needed for scientific advances? Perhaps we should be looking at the decline of Islamic science as a cautionary tale."
Geoffrey.landis writes: "By now we've all seen those maps of the US colored red and blue for which presidential candidate won a particular state. Those maps are a bit misleading, though, since vast areas of America have very low population. Mark Newman, of the University of Michigan, shows variant ways of mapping the election, with the maps distorted to un-distort the data."
Geoffrey.landis writes: "In the United States, climate scientists are subject to significant amounts of harassment , including "torrents of freedom of information requests, hate mail and even death threats from skeptics"-- but this phenomenon seems to be happening only in America. In other countries, climate scientists are mostly free to work without fear.
"The harassment has an intimidating effect—especially on young scientists," according to Stefan Rahmstorf, head of Earth system analysis at the Potsdam Institute for Climate Impact Research in Germany. Alan Leshner of the American Association for the Advancement of Science said he sees the attacks on scientists in the United States as "very disconcerting." Last year, AAAS released a statement condemning the harassment. "The incidents reflect two unfortunate things," Leshner said in an interview, "we live in a society where ideologies trump our willingness to hear what science says, and in a country where free speech is so widely valued, people are being attacked."
The only other country in which climate scientists routinely face harassment and death threats is Australia, which is the largest exporter of coal in the world. Coal industry groups in Australia have sought to cast doubt on climate science and have lobbied against carbon emission limits."

In the close-up view, you can see the disk-gap-band structure of the supersonic parachute. The story is available on several sites, including EarthSky and geek.com, or on the NASA MSL Image gallery"
Geoffrey.landis writes: "At last, a public opinion poll that gets the opinions of ordinary Americans on the issues that matter! Apparently, two thirds of Americans polled think that Barrack Obama is better suited to defend against an alien invasion than Mitt Romney, according to a survey from National Geographic Channel, done to tout their upcoming TV series "chasing UFOs". In follow-up questioning, Americans would rather call on the Hulk (21%) than either Batman (12%) or Spiderman (8%) to step to save the day. No word on which candidate is most fit to defend America against shambling hordes of undead seeking to destroy civilization in the zombie apocalypse (perhaps that will be brought out in the debates)."
Geoffrey.landis writes: "The courts have now ruled that the public has the right to videotape the police in the performance of their duties. Of course, that doesn't stop the police from harrassing people who do so, even journalists, not to mention confiscating their cameras. As it turns out, though, they're not always very knowledgable about how deletion works. I would say that erasing, or attempting to erase, a video of police arresting somebody illegally (How can a journalist be charged with "resisting arrest" when he was not being arrested for anything other than resisting arrest?) is a clear case of destruction of evidence by the officers. Destroying evidence is obstruction of justice. That's illegal. Why haven't these police officers been arrested?"
