Orbital Sciences restarts engine testing for its Taurus 2 rocket
Orbital Sciences has resumed engine testing for its Taurus 2 rocket.
While many have doubts about SpaceX, SpaceX has at least flown two successful flights of its Falcon 9 rocket. Orbital needs the Taurus 2 to supply ISS, and this rocket remains untested and as yet incomplete, with the schedule bearing down on them.

Reality always wins
Elon Musk’s talk yesterday at the National Press Club revealed several interesting things, about SpaceX’s rocket effort, about the state of the American commercial space industry, and about Elon Musk himself.
First, the company’s rocket design effort. Musk centered his talk on SpaceX’s new effort to make its Falcon 9 rocket completely reusable. Though he produced little specific details, and the moderator at the event asked no questions about it, it seems the engineering centers around these three concepts:

SpaceX suspends production of its Falcon 1 rocket
SpaceX suspends production of its Falcon 1 rocket.
As much as I am a fan of Elon Musk and SpaceX, and though I realize that they have been focusing on getting Falcon 9 and Dragon off the ground — the payoff there is greater and a failure of Falcon 1 during this time could be very politically painful — this action contradicts SpaceX’s years of claims that they had a slew of signed contracts to launch Falcon 1.
I will be attending Elon Musk’s luncheon speech today at the National Press Club, and hope to ask him about this and other things.

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.

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.

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.

Virtual monkeys typing Shakespeare
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.

A second large satellite will rain debris down in October
Even if UARS misses you today, don’t relax! A second large satellite, the 2.4 ton ROSAT X-Ray space telescope, is going to rain debris down late in October or early November.
On its ROSAT website, DLR estimates that “up to 30 individual debris items with a total mass of up to 1.6 tonnes might reach the surface of the Earth. The X-ray optical system, with its mirrors and a mechanical support structure made of carbon-fibre reinforced composite – or at least a part of it – could be the heaviest single component to reach the ground.”

The rover Opportunity as seen from Mars orbit
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.

The extension of Microsoft’s OS monopoly to hardware would be a disaster, with increased lock-in, decreased consumer choice and lack of space to innovate.
The article also notes how these restrictions might violate European Union competition law.
