Geothermal energy developers plan to pump 24 million gallons of water into a dormant volcano in Oregon this summer to demonstrate a new way to generate electricity.

The irony I glean from this article is this: Pumping water underground to produce energy from geothermal sources (a source liked by the environmental movement) is good. However, pumping water underground to produce energy from gas or oil (energy sources hated by the environmental movement) is bad. And yet, what difference really is there between either effort?

Occupy Wall Street Thugs Confiscate Man’s Home

9:42 am

Thugs: Occupy Wall Street has stolen a man’s home.

The real property owner is livid because he could be raising his two little girls, Imani, 3, and Kwazha, 10, in the two-story home instead of in a meager, two-bedroom rental in Brownsville while he tries to sort out his mortgage nightmare. … “[OWS] told me not to talk to them [reporters] because they [OWS] had an offer for me,” he said.

At a second meeting after the press conference, however, organizers said they would not pay him for the house. At that point, he told them to leave. Inside the house the walls are knocked down and all of his belongings, including a stove, refrigerator and bedroom furniture, have been moved to the basement.

Scientists have found that the structure of Titan’s atmosphere appears to change daily and seasonally, much like the Earth’s.

Scientists have found that the structure of Titan’s atmosphere appears to change daily and seasonally, much like the Earth’s.

“The most interesting point is that their model shows the presence of two different boundaries, the lower one caused by the daily heating and cooling of the surface – and varying in height during the day – and the higher one caused by the seasonal change in global air circulation,” commented Paulo Penteado from the Institute of Astronomy, Geophysics and Atmospheric Science at the University of São Paulo in Brazil. According to [Benjamin Charnay from the French National Centre for Scientific Research (CNRS) in Paris], this link between the lower atmosphere’s layers and the moon’s daily and seasonal cycle has never been seen on another moon or planet besides the Earth.

One caveat: the results are based upon a computer climate model. Though this model was tweaked based on actual data, that data remains slim and incomplete.

Phobos-Grunt due to crash to Earth anytime in the next ten hours

9:00 am

path of Phobos-Grunt's reentry

Updated and bumped. An updated prediction from Aerospace now calls for Phobos-Grunt to come down sometime between 9 and 3 pm (Eastern). This puts the U.S. now out of danger, though Europe, South America, Africa, Australia, and the southern half of Asia all remain in the spacecraft’s path.

Watch your heads! Phobos-Grunt is due to crash to Earth anytime in the next ten hours. And unfortunately, this new prediction has it flying over both North America and much of Europe and Africa during that time period.

NASA is soliciting private aerospace companies to bid on building their designs for rocket upper stage that will send the Orion capsule beyond Earth orbit.

NASA is soliciting private aerospace companies to bid on building their own designs for the rocket upper stage that will send the Orion capsule beyond Earth orbit.

This is good news: Rather than design the upper stage themselves, NASA is behaving like a customer and looking for someone else to provide them the product, much as the agency has been doing in buying from private companies crew and cargo services for ISS. Using this approach the agency is more likely to get its upper stage quickly and at less cost.

A private organization is now taking the White House to court over the president’s decision to install three new members on the National Board Relations board without Senate approval.

The court suits begin: A private organization is now taking the White House to court over the president’s decision to install three new members on the National Board Relations board without Senate approval.

Once again, President Obama’s decision to make these appointments in this unprecedented manner, when it was obvious the appointments would be challenged legally, was a terrible decision that will do no good and a great deal of harm. At minimum, it puts a cloud over anything these appointees do.

Above all, this action is further evidence that this President is an arrogant man with no interest in running the government in a manner that is reasonable or fair.

Obama asks for more power to consolidate government agencies

10:18 am

President Obama today asked Congress for additional power to consolidate six government agencies.

While this at first sounds like a very good idea, I must admit that it is difficult for me to trust this man with more power, at any time. In addition, how serious can we take his claim of desiring to save money when his administration is on a pace to increase the federal debt by more than $6 trillion, exceeding the debt accumulated by all Presidents from George Washington to Bill Clinton?

Engineers have gone to a back up radio system on Cassini after a primary unit did not respond as expected in late December.

Engineers have gone to a back up radio system on Cassini after a primary unit did not respond as expected in late December.

The cause is still under investigation, but age may be a factor. The spacecraft launched in 1997 and has orbited Saturn since 2004. Cassini completed its prime mission in 2008 and has had two additional mission extensions. This is the first time its ultra-stable oscillator has had an issue.

LightSquared seeks an investigation into one of the GPS advisory board members that said their system interferes with GPS

3:31 pm

LightSquared has announced that it is seeking an investigation into the GPS advisory board which said its system interferes with GPS.

On Thursday, the mobile broadband startup petitioned the Inspector General of NASA to investigate Bradford Parkinson, the vice chairman of a board that advises the government on GPS. Parkinson should be removed from discussions about potential interference between GPS and LightSquared’s proposed LTE (Long Term Evolution) network because he is also a director of GPS vendor Trimble Navigation, LightSquared said in its petition.

As lawyers say, when you’ve got the facts, pound the facts. When the facts are against you, pound the law. And when the law is against you, pound the table. Right now, LightSquared is pounding the law, as the technical results of the GPS investigation were quite clear: their system will interfere with most commercial and military GPS units.

That they went to the NASA Inspector General is instructive, since NASA has nothing to do with this issue.

Note that the law is also against LightSquared. I expect them to soon start pounding the table.

The Obama State Department has rejected the European code of conduct for space

3:21 pm

The Obama State Department made it known today that it has rejected the European code of conduct for space.

“Too restrictive,” Ellen Tauscher, undersecretary of state for arms control and international security, said of the 12-page document that seeks to promote the peaceful, safe and “transparent” use of outer space. Tauscher, speaking to a gathering of Washington, D.C.-based defense reporters on Jan. 12, let slip at the end of her talk that the State Department had rejected the document as it was written. While answering an unrelated question, she mentioned that, “we’re not going to be joining with the Europeans on their [space] treaty.” She did not share any further details as to what parts of the code were “too restrictive.”

Though I applaud the decision of the Obama administration to say no now, the article notes that Tauscher later admitted that the administration is still willing to negotiate this thing.

Why has Western civilization decided in recent decades that the solution to all problems is to lay down restrictions on what people can do? This authoritarianism goes against every ideal and principle that made our culture a success. Worse, it never works. Like gun control, the only people the rules harm are those who follow the rules.

X-Prize offers $10 million prize for anyone who can build McCoy’s tricorder

3:06 pm

Life imitates art: The X-Prize announced today a $10 million prize for anyone who can build McCoy’s tricorder from Star Trek.

The X PRIZE Foundation and Qualcomm Foundation said the prize, announced at the Consumer Electronics Show in Las Vegas, will go to the team that “develops a mobile platform that most accurately diagnoses a set of 15 diseases across 30 consumers in three days,” a release from the the two foundations said. The device must be light enough to be portable, weighing no more than 5 pounds.

The University of Connecticut has found the chief of its biology lab — an expert on the health benefits of drinking wine — guilty of falsifying and fabricating data on more than two dozen papers and grant applications.

More science fraud: The University of Connecticut has found the chief of its biology lab — an expert on the health benefits of drinking wine — guilty of falsifying and fabricating data on more than two dozen papers and grant applications.

A 60,000-page report issued yesterday (you can read a 49-page summary here) by [University of Connecticut Health Center] (UCHC) found [Dipak] Das guilty of 145 counts of fabrication and falsification of data, involving at least 23 papers and 3 grant applications. … UCHC has frozen externally funded research in Das’ lab, and it turned away $890,000 in federal grants while the investigation was underway. The university has also begun proceedings to fire Das.

Just as in the Stapel case in the Netherlands, we have here another example of the science community responding correctly to scientific fraud. Both examples stand in stark contrast to how the climate science community whitewashed the fraud and malfeasance in its own community.

Phobos-Grunt’s reentry this weekend

9:20 am

path of Phobos-Grunt's reentry

Watch your head this weekend: The re-entry of Phobos-Grunt has been refined, and is expected to come down sometime between 5 pm (Eastern), Saturday January 14 and 9 am (Eastern), Monday January 16.

As you can see by the image on the right, there is as yet no way to predict where it will land, though it appears that — except for the tip of Florida — North America is in the clear. The blue lines show its orbital path during the first half of this window, while the yellow lines show its path during the window’s second half.

SpaceX outlines its new design goals for Falcon 9

9:09 pm

What competition brings: SpaceX outlines its new design goals for Falcon 9 and its Merlin rocket engine.

[U]pcoming upgrades to the engine (Merlin 1D) will provide a vast improvement in performance, reliability and manufacturability – all of which could provide a timely boost to aiding the potential for success for the fully reusable Falcon 9.

Increased reliability: Simplified design by eliminating components and sub-assemblies. Increased fatigue life. Increased chamber and nozzle thermal margins,” noted SpaceX in listing the improvements in work.

Improved Performance: Thrust increased from 95,000 lbf (sea level) to 140,000 lbf (sea level). Added throttle capability for range from 70-100 percent. Currently, it is necessary to shut off two engines during ascent. The Merlin 1D will make it possible to throttle all engines. Structure was removed from the engine to make it lighter.

Improved Manufacturability: Simplified design to use lower cost manufacturing techniques. Reduced touch labor and parts count. Increased in-house production at SpaceX.

That’s just the engine. Most of the article however talks about the company’s effort to make as much of Falcon 9 reusable as possible. Hat tip to Clark Lindsey.
