Deep Impact fired its engines today to adjust its orbit, giving it the option of visiting a near Earth asteroid in the future.

The press release is very vague about this future mission. I suspect there is a question of funding, which means that even if they can go to the asteroid, they might not have the funds to staff the mission.

Astronomers have discovered a star that circles the supermassive black hole at the center of the Milky Way in only 11.5 years.

Dizzy: Astronomers have discovered a star that circles the supermassive black hole at the center of the Milky Way in only 11.5 years.

This newly discovered star joins another that is 15 times brighter and has a 16 year orbit. The combined orbital data from both will allow astronomers to measure precisely the size of the black hole while also measuring the distortion of space caused by its intense gravitational field.

A new study has found that scientific misconduct and fraud is on the rise.

A new study has found that scientific misconduct and fraud is on the rise.

A review of retractions in medical and biological peer-reviewed journals finds the percentage of studies withdrawn because of fraud or suspected fraud has jumped substantially since the mid-1970s. In 1976, there were fewer than 10 fraud retractions for every 1 million studies published, compared with 96 retractions per million in 2007.

The study’s authors suggest that the high pressure of big science might be a cause, combined with an overall decline in our culture itself. I wonder if the influence of government money, granted not because of good science but in the service of a political agenda, might also be a contributing factor.

A high school teacher threatened a student last Friday for wearing a Romney t-shirt on dress-down day.

Leftwing tolerance: A high school teacher in Philadelphia threatened a student last Friday for wearing a Romney t-shirt on dress-down day.

The teacher allegedly told the girl to take off the shirt, saying it was like wearing a Ku Klux Klan sheet. The teacher allegedly threatened to use a marker to cross out Romney’s name and that of Rep. Paul Ryan, his running mate. The teacher also allegedly tried to throw the student out of class. The teacher also allegedly said that Carroll was “a Democratic school.”

In order to get a seat on a Soyuz capsule Sarah Brightman outbid NASA, bumping its astronaut out and thus forcing the U.S. agency to finally agree to a year long mission.

Irony of ironies: In order to buy her seat on a Soyuz capsule Sarah Brightman outbid NASA, bumping its astronaut out.

This was a win-win for the Russians. They get paid more by Brightman than by NASA (over $51 million), and they finally get that year long mission they’ve been campaigning for for years. Because Brightman has taken one of NASA’s seats, the U.S. agency was forced to agree to the extended mission in order to maintain a presence on the station throughout that time period. Otherwise, their astronaut would come home and be replaced by Brightman, but for only ten days.

New research has now documented the widespread bigotry of liberals in the academic community against conservatives.

Leftwing tolerance: New research has now documented the widespread bigotry of liberals in the academic community against conservatives.

Hostility toward and willingness to discriminate against conservatives is widespread. One in six respondents said that she or he would be somewhat (or more) inclined to discriminate against conservatives in inviting them for symposia or reviewing their work. One in four would discriminate in reviewing their grant applications. More than one in three would discriminate against them when making hiring decisions. Thus, willingness to discriminate is not limited to small decisions. In fact, it is strongest when it comes to the most important decisions, such as grant applications and hiring.

This behavior is hateful, prejudiced, intolerant, and close-minded. And it is occurring against individuals merely because they disagree with the accepted orthodoxy of liberal academia. Worse, it is occurring in our universities among the educated elites of our society. Such close-mindedness among the educated cannot bode well for our society’s future.

Using data from the Spitzer Space Telescope astronomers have narrowed the universe’s rate of expansion to about 74.3 kilometers per second per megaparsec.

The uncertainty of science: Using data from the Spitzer Space Telescope astronomers have narrowed the universe’s rate of expansion to about 74.3 kilometers per second per megaparsec.

The importance of this number, also called the Hubble Constant, is that it allows astronomers to extrapolate more precisely backward to when they believe the Big Bang occurred, about 13.7 billion years ago. It also is a crucial data point in their effort to understand dark energy, in which this expansion rate is actually accelerating on vast scales.

Back in 1995 a team led by Wendy Freedman, the same scientist leading the work above, announced that they had used the Hubble Space Telescope to determine the expansion rate as 80 kilometers per second per megaparsec. Then, the margin of error was plus or minus 17 kilometers. Now the margin of error has been narrowed to plus or minus 2.1 kilometers.

Do I believe these new numbers? No, not really. Science has nothing to do with belief. I do think this is good science, however, and that this new estimate of the Hubble constant is probably the best yet. I would also not be surprised if in the future new data eventually proves this estimate wrong.

Light posting

9:10 am

Just a note to explain the light posting yesterday and possibly today. I am reviewing the proof for the new ebook edition of my first book, Genesis: the Story of Apollo 8. Because the book is now out of print in both hardback and paperback, I want to have this new edition published and available for sale before the end of this month, which is why I must focus on getting that done quickly.

The rollout to the launchpad of the first stage of Orbital Sciences’ Antares rocket has been delayed until Saturday.

The competition heats up: The rollout to the launchpad of the first stage of Orbital Sciences’ Antares rocket has been delayed until Saturday.

The rollout had been scheduled for today, but had to be scrubbed due to a battery problem in the transporter for moving the rocket. Once on the pad, they will then spend the next 4 to 6 weeks preparing for a hold down firing test. And if that test goes well, they will follow it up with the first launch of Antares before the end of the year.
