"Plans have probably already been cleared with the Obama Administration but have been kept under wraps in case Republican candidate Mitt Romney won," according to Space.com.
This computer simulation uses what we know about physical forces in the universe to model how a galaxy might have been born, and how it might grow over 13.5 billion years.
This cosmological simulation follows the development of a single disk galaxy over about 13.5 billion years, from shortly after the Big Bang to the present time. Colors indicate old stars (red), young stars (white and bright blue) and the distribution of gas density (pale blue); the view is 300,000 light-years across. The simulation ran on the Pleiades supercomputer at NASA's Ames Research Center in Moffett Field, Calif., and required about 1 million CPU hours. It assumes a universe dominated by dark energy and dark matter.
The result is a beautiful (if silent) video that is significantly labeled as public domain. It seemed like something you guys might enjoy playing around with.
"A giant planet with a liquid interior full of liquid beef and pork, into which a thousand earths would fit."
Darren Cullen of Spelling Mistakes Cost Lives and friend Mark Tolson edited together this 'lost episode' of Carl Sagan's Cosmos, about a fabled Meat Planet, with details of its famous pork volcano, Mount Sustenance, "well-known to astronomers since the time of Galileo."
If NASA would focus on the important planets, the delicious bacon-y ones like this, perhaps we'd have a real future in space exploration. Astronomy-gastronomy!
This video interview with Ashwin Vasavada, Deputy Project Scientist of the Mars Science Laboratory, is a nice overview of the what everybody's favorite currently operational Mars rover is looking for.
Here's a Google Map of the route, with stopping points. Big shuttle is big. Bigger than the streets that must accommodate her. Basically, the whole thing is like the ultimate slow-speed car chase, but with fewer live news choppers overhead.

For the second time in 2012, a SpaceX Dragon spacecraft has connected with the International Space Station. ISS expedition 33 crew members Akihiko Hoshide and Sunita Williams grappled Dragon and attached it to the station, completing a critical stage of the SpaceX CRS-1 cargo resupply mission.
OK, I know that I promised to never post anything ever again about a certain hypothetical disaster that rhymes with Schmapocalypse MiffyMelve, but hear me out. This really isn't about that. Instead, I want to highlight an excellent profile of a scientist whose work and interactions with the public have been affected by that unnamed bit of urban mythology.
David Morrison is a 72-year-old senior scientist at NASA's Ames Research Center. He runs NASA's "Ask an Astrobiologist" column, and considers it his way of following in the footsteps of Carl Sagan. In this story, written by Dan Duray at The Awl, we learn about Morrison's deep commitment to communicating science to the public ... a commitment that has led him to spend the last eight years answering a increasingly heavy flood of letters about the end of the world. It's an interesting look at the effects pop culture has on real people.
The questions that Dr. Morrison receives circle around a surprisingly cohesive set of theories, each grounded in some kind of real science that then veers off in a wild direction ... It's possible that many of the people who write to Dr. Morrison are trolls, or have Kindle books to sell, or want to garner enough YouTube views to merit an ad before their videos (some of the "Nibiru exposed" videos now feature a pre-roll for the conspiracy movie Branded). But his younger questioners certainly aren't faking it. He read me some of the more serious emails over the phone:
"I know that everyone has been asking you the same question but how do I know the world is not going to end by a planet or a flood or something? I'm scared because I'm in 10th grade and I have a full life ahead of me so PLEASE I WOULD REALLY LIKE AN ANSWER TO MY QUESTION."
"I am really scared about the end of the world on 21 December. I'm headed into 7th grade and I am very scared. I hear you work for the government and I don't know what to do. Can someone help me? I can't sleep, I am crying every day, I can't eat, I stay in my room, I go to a councilor, it helps, but not with this problem. Can someone help me?"
It's not all serious business, though. In one of the funnier moments, a 72-year-old man tries to figure out how to deal with YouTube commenters accusing him of being a secret Lizard Person.

My four year old son painted this at school and told his teacher, “This is Mars. Mars is red. And there is a robot there taking pictures and sending them back to earth.”
Mars Curiosity, eat your heart out.
When a narrow stream, flowing downhill, meets a wide, significantly-flatter valley, you get an alluvial fan — a place where the flow of water spreads out, slows down, and leaves behind all the rocks and sediment it's no longer moving fast enough to carry. At least, that's how it works on Earth.
Once upon a time, it may have worked that way on Mars, too. Yesterday, NASA announced that the Curiosity rover had documented geology that looks very much like an alluvial fan and rocky deposits that also look very much like what would be left in an alluvial fan on Earth. You can see the comparison of some of those in the image above. In these Martian geological features — as in an Earth-bound stream bed — you find smooth, rounded pebbles and conglomerates, masses of pebbles cemented together over time. The rocks photographed by Curiosity are also too large to have been blown into this sort of arrangement by the wind.
All of this adds to the long string of evidence that Mars once had flowing water on its surface. In fact, reading up for this post, I was surprised to see how much evidence there actually is for this, some direct and some indirect, stretching all the way back to the Mariner 9 orbiter mission in the early 1970s. And, of course, there is water on Mars right now. It's just not flowing water. Previous probes have measured a small amount of water in the Martian atmosphere, and the planet's polar regions contain both frozen carbon dioxide and frozen water. Viking 2 took pictures of frost on the ground in the late 1970s, and in 2008, the Phoenix lander literally dropped out of the sky onto a patch of ice.

This past weekend, I accompanied Miles O'Brien to the 50th anniversary of the Kennedy Space Center. In attendance were present and past KSC directors, NASA Administrator Charles Bolden, astronauts and space heroes of all eras—from Thomas Stafford to Cady Coleman—and many of the so-called "pad rats" who built spacecraft from the Apollo era through the Shuttle era. Miles delivered an amazing speech dedicated to those pad rats.

I never dreamed I would be in a NASA base in California, singing and playing music.
The Ground Control Opera performance by Nelly Ben Hayoun, presented the International Space Orchestra, 50 local technicians and scientists, playing in the city of San Jose at the Zero1 Biennial 2012. The opera reenacts the first minutes of Neil Armstrong's landing on the Moon. It's dedicated to the memory of the recently gone cosmonauts and astronauts, and the endeavors of scientists at ground-control stations, still trying to make our 20th century dreams of spaceflight come true.
My daughter asked me when she mis-heard that I was singing for "NASA": Mom why are you singing to "NATO?" NATO bombed us in Serbia in 1999! I said my dear this is NASA, not NATO, they have planes and rockets but not bombers and missiles! They are searching for habitable planets with the Kepler space probe! Maybe there are other space controllers somewhere out there!

If you're in California today, Friday, Sept. 21, you may have a chance to see space shuttle Endeavour's historic flyover of the state as it heads for the California Science Center in Los Angeles for retirement. Here are more details from NASA Dryden on the exact route and planned times.
The orbiter, atop its 747 Shuttle Carrier Aircraft (SCA), is scheduled to fly over northern California and a large area of the Los Angeles basin beginning at about 8:15 a.m. PDT. NASA originally planned the transit for an earlier hour, but rescheduled to increase the odds of good visibility for Bay Area residents—fog is a factor there in the early morning.
"During the four-and-a-half hour flight, social media users are encouraged to share their Endeavour sightings using the hashtags #spottheshuttle and #OV105, Endeavour's vehicle designation," according to NASA, and there's a Flickr group for space fans. The official account for NASA is here. At 11 a.m. EDT (8 a.m. PDT), NASA TV will air Endeavour's departure for the flyover.
NASA Ames' Twitter account is a good one to follow today, as is Boing Boing pal Todd Lappin, who shot the gorgeous photos in this post. SpaceFlightNow is liveblogging, and they're also great to follow on Twitter today.
