Archiving NASA’s social media | Bad Astronomy

NASA logoI sometimes make fun of NASA for being a bit stodgy, but in truth a lot of the folks there are pretty savvy when it comes to new tech and social media. The Mars rovers Spirit and Opportunity were on Facebook pretty quickly, and a flood of other space probes followed suit. Twitter is well-populated by NASA people, including astronaut Soichi Noguchi, who has been tweeting tirelessly from orbit recently, posting one amazing picture after another of cities, landscapes, and even the Moon.

One thing NASA is careful about is archiving material. They are well aware of the importance of the work they’re doing, and public outreach is a critical aspect of it. That’s why I’m happy to see a new effort on the part of the space agency to archive all their social media outlets.

It’s just started, so it’s a bit sparse, but I can see this being very useful to future historians. It may seem silly to have an online record of all the official tweets from NASA people, but in fact there is a wealth of information there. And it’s not just Twitter; it’s also Flickr for pictures, and YouTube for videos. I can see this expanding to Facebook, too, and other social networks. There’s a brief intro to the archive on the NASA images blog as well.

NASA does a pretty decent job of being transparent to its stakeholders — that’s you, folks — far better than most other government agencies, despite being online in far larger proportion than them as well. And I know that I’ll be able to use this archive for blogging; it’ll make linking to NASA efforts a whole lot easier. Not only that, but I found a couple of new Twitter streams form NASA I’m interested in, too! So take a look at the archive and dig around. I just bet you’ll find something cool there.

Obama to House Democrats: We’re Communitarians, not Individualists

It's the Republicans who are into Selfishness

From Eric Dondero:

Very late in the campaign of 2008, in at least two speeches, Barack Obama took a direct jab at individualist philospher Ayn Rand. He seemed completely aware of Rand's philosophy. In one election even speech delivered at Tampa, Florida, Obama criticized the "virtue of selfishness," the title of one of Rand's most successful books.

Here's the quote from Oct. 31, 2008:

"John McCain and Sarah Palin they call this socialistic. You know I don’t know when, when they decided they wanted to make a virtue out of selfishness."

And here's the quote in a slightly different form, from a speech delivered in Ohio, Nov. 2, 2008 as reported by Jake Tapper of ABC News, Nov. 3:

"The change we need won’t come from government alone," Obama said to a crowd of an estimated 80,000. "It will come from each of us doing our part in our own lives, in our own communities. It will come from each of us looking after ourselves and our families but also looking after each other. You know I – it’s been awhile now – we’ve made a virtue out of selfishness, there’s no virtue in that. We made a virtue of irresponsibility and we need to usher in a new spirit of service and sacrifice and responsibly."

Community over Liberty

Now, he's at it again, bringing up the subject of individualism last night in a health care vote eve pep rally to Democrat Congressman.

Transcript from the Washington Post:

Something inspired you to get involved, and something inspired you to be a Democrat instead of running as a Republican. Because somewhere deep in your heart you said to yourself, I believe in an America in which we don’t just look out for ourselves, that we don’t just tell people you’re on your own, that we are proud of our individualism, we are proud of our liberty, but we also have a sense of neighborliness and a sense of community -- (applause) -- and we are willing to look out for one another and help people who are vulnerable and help people who are down on their luck and give them a pathway to success and give them a ladder into the middle class. That’s why you decided to run. (Applause.)

Toyota's Torment Justified?

An article on Wall Street website The Street.com notes that Toyota is not the only car company currently revealing vehicle defects and issuing recalls. That story lists Chrysler, Ford, GM, Honda, and Nissan among others. And it reports that six major carmakers, including Ford, have received complain

Maintaining Valves for Safety

A chain of events led to the devastating chemical accident at the Union Carbide chemical facility in Bhopal, India, on Dec. 3, 1984. Some of it was management's fault such as dismantling refrigeration systems and scrubbers, and some blame was on workers who ignored safety procedures or did not prote

Are Fywheels Fly-by-night?

The use of flywheels to store energy has recently hit the auto racetrack. But other than for short bursts of electric power for passing, do you think such a system is practical for everyday passenger vehicles?

Framers Believed in Virtuous (ie, Humane) Government

The Tea Party movement is not completely cuckoo. In fact, its focus on the Constitution should be welcomed by all Americans.

When tea partiers inquire closely into the Constitution’s original intent, they will find what they expect to find: it was created, first, to protect individual liberty from overzealous government.

Yet they may be surprised when they learn that Franklin, Washington, Hamilton, Adams, Jefferson and Madison – as bitterly contentious in politics as present-day politicians (if not more so) – all agreed on the one bedrock principle upon which any good government depended: VIRTUE – or, literally, “Public Spirit.”

As Thomas Paine (Common Sense, The Rights of Man, etc.) insisted: “Public good is not a term opposed to the good of individuals. On the contrary, it is the good of every individual collected. It is the good of all, because it is the good of every one.” Hence Paine advocated progressive taxation, aid to the unemployed, and free public education.

Healthcare-for-all, anyone?

BREAKING!! Video of "Racial Slurs" at Tea Party shows Big Media lie

Ugly yes; but no racial remarks

From Eric Dondero:

Far Left websites such as Huffington Post and Firedog Lake reported with glee late yesterday, on alleged "racial slurs" hurled at black members of Congress as they passed a gauntlet of Tea Party protesters, while entering the Capitol. Big media have picked up on the story this morning, from ABC News, to the NY Times, to the Washington Post.

This is how MSNBC reported on the story "Protest gets Ugly, Racist":

From NBC's Luke Russert
The Tea Party protests got ugly today.

African-American Congressman John Lewis (D-GA), a protege of Dr. Martin Luther King Jr., who helped organize the March on Washington, went to the House floor today to tell Majority Whip Jim Clyburn (D-SC) that a Tea Party protester called him a "n-----."

But the video tells a different story. "Ugly," yes. But absolutely no racial ephitats can be heard and further no evidence on the video of anyone being spat upon.

HotAirPundit (not HotAir.com), has a second video of Cong. John Lewis leaving the Capitol. Once again, absolutely no racial slurs are heard. HA Pundit asks:

Is it possible that John Lewis didn't hear any racial slurs, but 'Deemed' it to be so when he talked to Reporters?

Major hat tip to Barry Goldwater-ian blog BasilsBlog for uncovering the video.

Candor Chasma

Click here to view the embedded video.

This animation of a virtual flight over of the southwestern part of the Candor Chasma on Mars was made from HiRISE Digital Terrain Models (DTM’s).  Essentially DTM’s are made from two images of the same area on the ground taken from different angles, a stereo pair. The process of going from a stereo pair to a DTM is the hard part. Happily we have people who are up to the challenge.

The great thing about the DTM is the high resolution of the source imagery, the HiRISE images coming from the Mars Reconnaissance Orbiter are normally between 0.25 and 0.5 m/pixel.  The derived terrain is about four times the source, so we are talking a vertical precision in the tens of centimeters. 1

CONFIRMATION: "20,000" at Tea Party protest at Capitol in Washington

Three Capitol Hill officers confirm count

From Eric Dondero:

The big media this morning, is almost entirely ignoring the size of the Tea Party protest crowds at the Capitol yesterday. But one outlet lets it slip, though buried down in their story.

Reporter Salena Zito with the Pittsburgh Tribune-Review has this report, 17 paragraphs down, (notably not the headline of the story), in an article "Tea Party heard as D.C. focus of Protest":

Capitol Hill Police do not officially comment on crowd sizes. Yet three officers at separate vantage points estimated the rally's attendance more than 20,000, based on the number of people that typically can fill the lawn.

Michele Bachmann while speaking to the rally estimated "25,000." Later, Fox News reported "thousands." MSNBC reported "between 1,500 to 2,000 Tea Party protesters."
