Exploring an abandoned mine in Nevada
An evening pause: From the youtube webpage:
This inclined shaft is located outside of Searchlight, NV. The shaft itself is about 350 feet deep with two extensive drift levels along its length. We found a winze [a vertical shaft] in the lowest drift level that went down to what appeared to be an additional level.
I must emphasize that mines are very dangerous, and should be approached with great care and caution. Unlike a cave, which has had eons to slowly establish its stable structure, a mine is cut into the rock instantly (compared to geological time), and is thus very unstable and prone to collapse.
Energy Department approves $737 million solar loan guarantee
More money wasted? The Energy Department has approved another solar power company loan guarantee, this for $737 million.
I’m not sure this project will go belly-up, as Solyndra did. I just find it questionable for this to be approved at this moment.
A new report from the EPA Office of the Inspector General has said that EPA violated its own peer review process in determining that greenhouse gases endanger “the public health and welfare.”

The coming blindness of astronomy
The European Southern Observatory today released this infrared image today of what astronomers have named the Fried Egg Nebula. Taken by the Very Large Telescope in Chile, the picture shows the concentric dust shells surrounding a post-red supergiant star, thought to be transitioning to the next stage of stellar evolution called a yellow hypergiant. As the press release explains,
The monster star, known to astronomers as IRAS 17163-3907, has a diameter about a thousand times bigger than our Sun. At a distance of about 13 000 light-years from Earth, it is the closest yellow hypergiant found to date and new observations show it shines some 500 000 times more brightly than the Sun. . . . If the Fried Egg Nebula were placed in the centre of the Solar System the Earth would lie deep within the star itself and the planet Jupiter would be orbiting just above its surface. The much larger surrounding nebula would engulf all the planets and dwarf planets and even some of the comets that orbit far beyond the orbit of Neptune. The outer shell has a radius of 10 000 times the distance from the Earth to the Sun.
Yellow hypergiants are in an extremely active phase of their evolution, undergoing a series of explosive events — this star has ejected four times the mass of the Sun in just a few hundred years. The material flung out during these bursts has formed the extensive double shell of the nebula, which is made of dust rich in silicates and mixed with gas.
According to the science paper [pdf] describing this research, the stage of yellow hypergiants is a preliminary to the star evolving into a luminous blue variable, of which Eta Carinae is the most famous. In this next stage a star is thought to have a good chance of going supernova.
Though this image is truely spectacular, taken by a ground-based telescope of a star 13,000 light years away, what I find most significant about this image is its fuzziness. It reminds me of the kind of images astronomers and the public routinely accepted as the best possible, before the launch of the Hubble Space Telescope.

NASA proposes major reconstruction of its launch facility at the Kennedy Space Center
NASA proposes major reconstruction of its launch facility at the Kennedy Space Center.
They say this modernization is intended to make Kennedy more competitive in the modern commercial space market, which I am sure is true. Another way to look at it, however, is that Kennedy is getting favored treatment by the government, receiving a huge subsidy from NASA that the other private spaceports in New Mexico and elsewhere were not even allowed to compete for.
Orbital Sciences has launch success
Orbital Sciences has a launch success, putting an Air Force reconnaissance satellite into orbit from the Kodiak Launch Complex in Alaska.
For Orbital, this success cleans off some of the stain left on the company from the recent launch failures of its Taurus 1 rocket. What would leave the company stainless, however, will be a successful first launch of its new Taurus 2 rocket, needed to carry its Cygnus capsule to ISS and scheduled for late this year.
NASA science administrator Ed Weiler is retiring after 33 years
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.

Facing possible inquiry, OnStar drops ‘Big Brother’ plans
Facing outraged criticism, General Motors’ OnStar division has dropped its plans to track and record the personal driving information of both former and current subscribers.
Sounds good, but I wouldn’t assume this story is over. I also wouldn’t be surprised if they try again later to sneak this data grab by everyone.
Loreena McKennitt – The Stolen Child
An evening pause: William Butler Yeats’ poem, The Stolen Child, set to song.
Away with us he’s going,
The solemn-eyed:
He’ll hear no more the lowing
Of the calves on the warm hillside
Or the kettle on the hob
Sing peace into his breat,
Or see the brown mice bob
Round and round the oatmeal-chest.For he comes, the human child,
To the waters and the wild
With a faery, hand in hand,
From a world more full of weeping
than he can understand.
