The largest dam removal in U.S. history has begun in Washington.
The article is remarkably vague about how this source of electrical power will be replaced.
Obama to propose $1.5 trillion in new taxes today.
A quick look at this proposal tells me that most of it is made of gimmicks and smoke and mirrors. The cuts are elusive, while the tax increases are real. More important, none of it actually appears to cut spending at all, merely reducing the rate that spending increases over the next decade.
Sadly, I don’t expect anything much better from the present Republican leadership.

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
China has resumed rocket launches after an August failure, putting a communications satellite into orbit.
This bodes well for the pending launch of the country’s first space station module, Tiangong 1.
Now available in hardback and paperback as well as ebook!
From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.
All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount.

"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke

The uncertainty of science: Astronomers have determined that the star that went supernova in the Whirlpool Galaxy (M51) in June — making it the nearest supernova in 25 years — was a yellow supergiant star, not an aging red supergiant as predicted by theory. From the preprint paper:
Despite the canonical prediction that Type II supernovae arise from red supergiants, there is mounting evidence that some stars explode as yellow supergiants. A handful of Type II supernovae have been observed to arise from yellow supergiants: supernovae 1993J, 2008cn, and 2009kr. The locations of the progenitors on the Hertzsprung-Russell diagram shows clearly that these stars are not located on the predicted end points for single star stellar evolution tracks. In addition, despite arising from supposedly similar yellow supergiant progenitors, these supernovae display a wide range of properties.
The Hertzsprung-Russell diagram is a graph mapping the color of stars against their luminosity. Because color and brightness change as the star evolves over time, the graph is used by astronomers to track the birth, growth, and death of stars. That these yellow supergiants don’t appear to be at “the predicted end points for single star evolution” on the diagram is a serious problem for the theorists who have tried to explain what causes this particular type of supernova.
Which also means astronomers are still unable to tell us what stars in the sky are most likely to go supernova in the future.

Union civility: A union in Washington state has been held in contempt for the violence that took place during a protest at a grain terminal. Some testimony:
Security guard Charlie Cadwell, employed by Columbia Security for patrols at the Longview grain terminal for the past two months, told the judge of the harrowing experience: Every protester he saw that night was carrying a weapon – baseball bats, lead pipes, garden tools. “I didn’t see a longshoreman who didn’t have something in his hands,” he said.
He was was pulled out of his car by one longshoreman, and another man swung a metal pipe at him, he said. “I told him, ‘You have 50 cameras on you and law enforcement is on its way,'” Cadwell said. “He said, ‘(expletive) you. We’re not here for you, we’re here for the train.'”
In the meantime, someone drove off with his car and eventually ran it into a ditch. Cadwell said about 40 to 50 people were throwing rocks at him, and that he was hit between his eyes and in his knee.

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.

The engine of Japan’s troubled Venus probe, Akatsuki, has been found too damaged to put the probe into Venus orbit.
JAXA conducted a test ignition of the probe’s main engine on Wednesday to prepare for another attempt to send it into orbit in 2015. But the thrust produced was only one-eighth the amount anticipated, the space agency said. The damage the engine suffered last December when JAXA ignited it in the initial attempt to send the probe into orbit around Venus appears to be more serious than thought, JAXA said.
One of the two three-man crews on ISS have returned safely to Earth, despite an unexpected communciations blackout during their descent.
In related news, the Russians have slightly delayed the launch dates for the next manned flights to ISS, which also means that the next test flight of Falcon 9/Dragon will have to be delayed until 2012. Moreover, the Russians are once again balking at allowing Dragon to dock with ISS on this first flight.
An evening pause: Walking on water. As the youtube website explained, “They filled a pool with a mix of cornstarch and water made on a concrete mixer truck. It becomes a non-newtonian fluid. When stress is applied to the liquid it exhibits properties of a solid.”
A four-star Air Force general told a congressional committee last week that the White House pressured him to soften his testimony concerning the military’s opposition to the technology being used by the broadband company Lightsquared– a major Democratic campaign donor — because it interfered with GPS signals.
In a related update, LightSquared boss said Wednesday that the company is near an engineering breakthrough that will solve the technical issues that worry GPS users.
Clark Lindsey takes another look at the cost for building the Congressionally-mandated heavy lift rocket, what NASA calls the Space Launch System and I call the program-formerly-called-Constellation. Key quote:
Finally, I’ll point out that there was certainly nothing on Wednesday that refuted the findings in the Booz Allen study that NASA’s estimates beyond the 3-5 year time frame are fraught with great uncertainty. Hutchison and Nelson claimed last week that since the near term estimates were reliable, there’s no reason to delay getting the program underway. That’s the sort of good governance that explains why programs often explode “unexpectedly” in cost after 3-5 years…
In other words, this is what government insiders call a “buy-in.” Offer low-ball budget numbers to get the project off the ground, then when the project is partly finished and the much higher real costs become evident, Congress will be forced to pay for it. Not only has this been routine practice in Washington for decades, I can instantly cite two projects that prove it:

Virgin Galactic expects to make its first launch of SpaceShipTwo within a year.
“The mother ship is finished… The rocket tests are going extremely well, and so I think that we’re now on track for a launch within 12 months of today,” [Richard Branson] told CNN’s Piers Morgan late Wednesday.
