And in related news, a new computer simulation suggests that the very first stars were not the giant monsters scientists had predicted.
A new analysis of data suggests that the asteroid Lutetia is a leftover fragment from the same original material that formed the Earth, Venus and Mercury.
It looks bad for Phobos-Grunt.
“Overnight, several attempts were made to obtain telemetric information from the probe. They all ended with zero result,” Interfax quoted a source in the Russian space sector as saying. “The probability of saving the probe is very, very small,” added the source, who was not identified.
Peace and love: A man was shot and killed at the Occupy Oakland camp today. Plus, an immediate effort by the protesters to squelch the press:
Reporter Aimee Allison of the Chronicle says she was attacked when she tried to take a cell phone photo. And she wasn’t the only one: “A few feet away a TV cameraman was shooting footage and a crowd of twenty or so men attacked and punched him, forcing him over the railing of the 14th Street BART Station.” Which means, even in the best-case scenario, there was an unconnected murder right next to the camp and a mob of protesters decided to do “damage control” by beating the hell out of journalists who were trying to report on it. That’s where we’re at here.
NASA has chosen the Delta 4 Heavy rocket to launch the Orion capsule into orbit for its first test flight in 2014.
So, tell me again why NASA needs to spend $18 to $62 billion for a new rocket, when it already can hire Lockheed Martin to do the same thing? Though the Delta 4 Heavy can only get about 28 tons into low Earth orbit, and only about 10 tons into geosynchronous orbit — far less than the planned heavy-lift Space Launch System rocket — Boeing Lockheed has a variety of proposed upgrades to Delta 4 Heavy that could bring these numbers way up. Building these upgrades would surely be far cheaper than starting from scratch to build SLS.

These four stories, all in today’s news, all suggest that the heart of the Occupy Wall Street movement is strongly intolerant, filled with angry hatred, and prone to violence. Sadly, they appear to a small subset of a much larger sampling of similar stories.
In Oakland Occupy protesters have withdrawn a resolution to remain peaceful.
A small number of the protesters have openly called for the use of violence as a tactic to get their message out.
In Berkley, dozens of Occupy protesters were arrested yesterday. The cause:
The university reported earlier that an administrator had told the protesters they could stay around the clock for a week, but only if they didn’t pitch tents or use stoves or other items that would suggest people were sleeping there. The protesters voted not to comply with the demand and to go ahead with setting up a tent site they dubbed “Occupy Cal” to protest financial policies they blame for causing deep cuts in higher education spending.
In New York, a man was arrested for assaulting a paramedic and breaking his leg Wednesday night.
And finally, there is this eight minute video, where a Occupy Portland protester curses and threatens a news crew repeatedly until the police finally arrive to escort him away.
According to GPS data gathered over the past two decades, it appears that the New Madrid fault in Missouri might be shutting down.
The Dutch scientists who faked the data on dozens of papers has given up his doctoral degree.
Lightning! With pictures and video.
NASA successfully test-fired today the upper stage engine of its heavy-lift rocket, part of the Space Launch System, formerly called the Constellation program.
An evening pause: In honor of the fall of the Berlin Wall on this day in 1989, I post below Part 2 of a documentary on the history of the Wall’s construction and the many escape attempts by East Germans. Though the documentary does a poor job of explaining why East Germans desperately made attempt after attempt to flee to the west (a wish to escape from oppression and go somewhere where they could freely live their lives), it does include some incredible film footage showing the various escape attempts. Part 1 outlines the Wall’s initial construction, during which many people could easily break through.
Part 2, embedded below, describes the first deaths, when the communist East German government gave its guards orders to “shoot to kill.” Part 3 is even more fascinating, showing the effort by West Germans to dig tunnels under the 150 foot death strip in order to get friends and relatives out. Parts 4 and 5 show later attempts, when the Wall had become more impregnable, including one escape using an arrow (!) and another using two ultralight airplanes. Part 6 shows the Wall’s fall in 1989.
For twenty-eight years a government decided it had the right to imprison its citizens because they longed for freedom. In the end, all that government really achieved was to prove that freedom is better, and that good intentions — based on intellectual ideology and imposed on people by force — lead nowhere but hell.
Russia has two weeks to save Phobos-Grunt.
More info on the engine failure of Phobos-Grunt, and what might still be done to save the mission.
As it does every month, NOAA’s Space Weather Prediction Center today released its monthly update showing the ongoing changes of the Sun’s solar cycle sunspot activity. I have posted the graph below the fold.
For the fourth month in a row the Sun’s sunspot activity has leaped upward. In fact, for the first time since I have been tracking sunspot activity, beginning in 2008, the Sun’s sunspot activity exceeds the predicted activity by a significant amount. Since the end of the previous maximum, the Sun had consistently failed to meet the expectations of solar scientists by producing far fewer sunspots than expected.
In the past few months, however, the Sun has recovered, its activity firing upward, including some of the most active and largest sunspots in years.

Phobos-Grunt appears to be in trouble in Earth orbit.
In a posting to an online forum for the Phobos-Grunt mission, Anton Ledkov of the Russian Space Research Institute reported that there was “no telemetry” from the spacecraft.
Another report suggests that a variety of engine thrusters did not fire as planned.
An evening pause: In celebration of election day. This might have been made for the 2008 election, but it is remarkably up-to-day now, three years later.
To leap or not to leap: Scientists are considering abandoning the solar year as their method for synchronizing their atomic clocks.
At issue is whether to abolish the ‘leap second’ — the extra second added every year or so to keep [Coordinated Universal Time] (UTC) in step with Earth’s slightly unpredictable orbit. UTC — the reference against which international time zones are set — is calculated by averaging signals from around 400 atomic clocks, with leap seconds added to stop UTC drifting away from solar time at a rate of about one minute every 90 years.
Mars Express takes a close look at one of Mars’ giant volcanoes, Tharsis Tholus.
At least two large sections have collapsed around its eastern and western flanks during its four-billion-year history and these catastrophes are now visible as scarps up to several kilometers high. The main feature of Tharsis Tholus is, however, the caldera in its center. It has an almost circular outline, about 32 x 34 km, and is ringed by faults that have allowed the caldera floor to subside by as much as 2.7 km.
NASA has moved the scheduled first flight test of the Orion capsule up three years to 2014.
This action, while good, was almost certainly triggered by the competition from the private space companies. The managers at NASA are finally realizing that if they don’t speed up deployment of their own spacecraft, they will certainly lose in the competition for government dollars. That they will have to use another rocket other than their heavy-lift vehicle for this launch, however, will not help that particular project’s lobbying effort.
Either way, I think this action is only further proof that the more competition we have, the quicker we will get into space. And the journey will cost less too, not only because it will take less time and therefore less money, but the competition between companies (or NASA) will force everyone — including NASA — to lower costs to show they can do it better.
A gallery of Occupy Wall Street hatred.
I think this collection of stories from the various “Occupy Whatever” protests gives a good flavor of what this protest movement stands for. And unlike the tea party protests, it appears that it is the violent extremists that form the movement’s heart.
And then there’s this, recorded yesterday in New York. Note: Language warning.
The day of reckoning looms: We’re still not cutting.
In the spring fight to avert a government shutdown, Republicans promised $100 billion in real cuts but then compromised for $38.5 billion in future savings. In reality, the Congressional Budget Office found the deal still resulted in an increase of more than $170 billion in federal spending from 2010 to 2011. The “largest spending cut in history” ended up being a spending increase.
And this:
But the [super]committee isn’t really trying to cut spending. It seeks only to spend the country into bankruptcy a little slower. Rather than letting the country rack up $23.4 trillion of debt by 2021, the supercommittee hopes to keep it to $21.3 trillion. It’s the difference between speeding off a cliff at 91 miles per hour versus 100 miles per hour.
DARPA has launched a program to use airplanes as a launchpad for putting satellites in orbit.
The Pentagon’s research agency, the Defense Advanced Research Projects Agency (DARPA), also anticipates slashing small satellite payload costs from more than $30,000 per pound to less than $10,000 per pound — making such launches three times cheaper. . . . DARPA wants the program to demonstrate at least 12 launches of 100-pound payloads to low Earth orbit, with each launch costing about $1 million. Launches could start as soon as 2015, according to DARPA’s official announcement of the program on Nov. 4.
At first glance this appears to be good news for Orbital Sciences and its Pegasus rocket, the only commercial launch system that has successfully put satellites into orbit using a commercial L1011 airplane as its first stage. At the same time, however, it appears DARPA is pushing for new technology to lower costs below what Orbital charges, meaning the game is open to anyone.
An evening pause: From a 1995 television profile of Dame Judi Dench, ending with her performance of “Send in the Clowns” from a revival of Stephen Sondheim’s A Little Night Music.
NASA’s Deep Space Network has captured a radar image of asteroid 2005 YU55, set to buzz past the Earth tomorrow.
The Lunar Reconnaissance Orbiter team has released a wide angle side view image of the Apollo 15 landing site, showing the lunar module and the areas around Hadley Rille and the Apennine Mountain range that the astronauts explored using their lunar jeep. Below is a cropped close-up, showing the landing site near the top of the image with Hadley Rille near the bottom. Below the fold is a second image showing a wider view that includes the Apennine mountain slope that the astronauts drove their rover up.
On another campaign note, a new website, put together by some noted conservative Republicans, has just appeared called Not Mitt Romney. An explanation can be found here.
Remember how Nancy Pelosi said we need to pass Obamacare “so you can find out what’s in it?” Well, is it any different with Mitt Romney? Does anybody really have the slightest idea what he’d do as President? Nobody can even reasonably predict where the guy will be on any issue six months from now, much less what he’ll do if he becomes the leader of the free world.
