Mars Express takes a close look at the Mars volcano Tharsis Tholus

12:20 pm

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 moves first flight test of Orion capsule up three years to 2014

12:16 pm

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

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.

We’re still not cutting

8:49 am

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 the launchpad for putting satellites in orbit

8:47 pm

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.

A breathtaking view of the Apollo 15 landing site

2:03 pm

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.

New conservative website: Not Mitt Romney

1:01 pm

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.
