NASA science administrator Ed Weiler is retiring after 33 years

9:12 am

Science administrator Ed Weiler is retiring after almost 33 years at NASA.

Among Weiler’s many achievements, he was crucial to getting the Hubble Space Telescope launched. Even more important, though others had conceived the idea of using the shuttle to maintain Hubble, he designed the maintenance schedule for the telescope. Seven years before it was launched, he insisted that a regular schedule of repair missions be placed on the shuttle manifest. He also insisted that a duplicate of the telescope’s main camera be built, so that if anything went wrong with the first a repaired unit could be launched quickly. It was his foresight here that made the first repair of Hubble in December 1993 go so smoothly. For this, astronomers will always be grateful.

Virtual monkeys typing Shakespeare

3:32 pm

A computer programmer has created a legion of virtual monkeys programmed to randomly type until the works of Shakespeare are reproduced.

If the nine-letter sequence appears anywhere in one of Shakespeare’s writings, it is matched against the relevant passage in a copy of the Bard’s complete works, and is checked off the list. The monkeys, which started typing on August 21, have already completed more than five trillion of the 5.5 trillion possible nine-letter combinations, but have so far only finished one whole work.

They appear to be doing better than Congress’s attempt to balance the federal budget.

Obama: “You’ve got a governor whose state is on fire denying climate change.”

1:58 pm

Obama on Sunday at a fundraiser, attacking Rick Perry: “You’ve got a governor whose state is on fire denying climate change.”

Here is another example of a politician making a fool of himself. The wildfires in Texas have nothing to do with climate change. And if Obama thinks they do, he immediately shows himself to be completely ignorant of the science behind the Earth’s climate.

Faster than light?

10:05 am

Can neutrinos travel faster than light? After three years of gathering data, an experiment at CERN says they do, though by only a tiny amount.

[Physicist Antonio] Ereditato says that he is confident enough in the new result to make it public. The researchers claim to have measured the 730-kilometre trip between CERN and its detector to within 20 centimetres. They can measure the time of the trip to within 10 nanoseconds, and they have seen the effect in more than 16,000 events measured over the past two years. Given all this, they believe the result has a significance of six-sigma — the physicists’ way of saying it is certainly correct.

You can download and read a preprint of their paper here.

What I find intriguing about this result, other than its exciting groundbreaking possibilities, is how it illustrates sharply the contrast between normal and healthy science, and the sad and sick state of the field of climate science.

An international team of scientists said on Thursday they had recorded sub-atomic particles traveling faster than light

5:03 pm

An international team of scientists said on Thursday they had recorded sub-atomic particles that travel faster than light.

A total of 15,000 beams of neutrinos — tiny particles that pervade the cosmos — were fired over a period of 3 years from CERN toward Gran Sasso 730 (500 miles) km away, where they were picked up by giant detectors. Light would have covered the distance in around 2.4 thousandths of a second, but the neutrinos took 60 nanoseconds — or 60 billionths of a second — less than light beams would have taken. “It is a tiny difference,” said Ereditato, who also works at Berne University in Switzerland, “but conceptually it is incredibly important. The finding is so startling that, for the moment, everybody should be very prudent.”

The rover Opportunity as seen from Mars orbit

Opportunity on Endeavour Crater rim

The image to the right was taken by Mars Reconnaissance Orbiter, with the white arrow showing the Mars rover Opportunity perched on the rim of Endeavour Crater.

The rover’s scientists hope that the rocks found on the crater rim, dredged up from deep below when the crater impact occurred, will be the oldest rocks so far touched on the Martian surface, and thus give them a peek at ancient Martian geology.

Senate panel trims NIH budget

6:17 pm

Now for some good reporting: A Senate committee today approved an NIH budget that trimmed the health agency’s budget by $190 million.

This report actually gives us an accurate description of the proposed budget, which offers a 2012 budget of $30.5 billion compared to the $30.7 that NIH got in 2011. For further context, note that the 2012 budget is still more than the agency got in 2009 ($30.2 billion), and more than a billion above what it got in 2008 ($29.2 billion). Anyone who cries poverty at this budget cut immediately discredits themselves.

Farmers flee as Indonesia’s Mount Tambora volcano rumbles

3:32 pm

Farmers begin fleeing as Indonesia’s Mount Tambora volcano comes back alive.

Villagers like Hasanuddin Sanusi have heard since they were young how the mountain they call home once blew apart in the largest eruption ever recorded — an 1815 event widely forgotten outside their region — killing 90,000 people and blackening skies on the other side of the globe. . . . The April 1815 eruption of Tambora left a crater 7 miles (11 kilometers) wide and half a mile (1 kilometer) deep, spewing an estimated 400 million tons of sulfuric gases into the atmosphere and leading to “the year without summer” in the U.S. and Europe.

Blurred vision a risk for astronauts who spend months in space

8:34 am

Blurred vision is now considered a serious risk for astronauts who spend months in space.

According to one NASA survey of about 300 astronauts, nearly 30 percent of those who have flown on space shuttle missions – which usually lasted two weeks — and 60 percent who’ve completed six-month shifts aboard the station reported a gradual blurring of eyesight.

This story is a followup on information contained in an earlier National Academies report on astronaut staffing.

New exoplanets make astronomers long for a telescope to see them

2:39 pm

The plethora of new exoplanet discoveries has astronomers longing for a telescope that can see them up close.

Astronomers need either a giant space telescope equipped with a device for blocking starlight, or an interferometer, consisting of several telescopes flying in formation. NASA did develop a proposal for such a space telescope, called Terrestrial Planet Finder, and the European Space Agency hoped to fly a similar mission called Darwin. But budgetary constraints have left both missions in limbo, unlikely to advance to the front of either agency’s queue until well into the next decade. At the conference, Traub raised the issue. “People are not thinking deeply about the distant future. People are wrapped up with what they’re doing right now,” he says. “Clearly, I’m concerned.”

Video from Dawn

9:39 am

NASA has released an update summarizing what scientists have found since Dawn went into orbit around Vesta in July. The video below, compiled from images Dawn has taken, gives a nice visual overview. The most interesting big feature, understated by the video, is the series of grooves that appear to encircle the asteroid’s equator. To my eye it almost looks like Vesta was once two asteroids that got merged into one, with these grooves indicating the weld point.

The direct link to the video can be found here.
