For no other reason than that they are gorgeous, the Cassini imaging team is releasing today a set of fabulous images of Saturn and Titan...in living color...for your day-dreaming enjoyment. Note that our presence at Saturn for the last 8 years has made possible the sighting of subtle changes with time, and one such change is obvious here. As the seasons have advanced, and spring has come to the north and autumn to the south throughout the Saturn system, the azure blue in the northern winter Saturnian hemisphere that greeted Cassini upon its arrival in 2004 is now fading; and it is now the southern hemisphere, in its approach to winter, that is taking on a bluish hue.
[B]ack here on Earth, the Cassini mission was recently given rave reviews by a panel of planetary scientists and NASA program managers for its contributions to our understanding of the solar system, a circumstance that bodes well for a well-funded continuing mission over the next 5 years. Despite the fact that we can't know exactly what the next five years will bring us, we can be certain that whatever it is will be wondrous.

Steve shared some amazing conversations with the "First Man," from what I can tell.
Tang is a farce. That was the first thing Neil Armstrong told me last night. “We did not use it on the Apollo missions.”
I asked him, of all of the systems and stages of the mission, which did he worry about the most? (the frequently failing autopilot? the reliance on a global network of astronomers to spot solar flares in time to get the warning out? the onboard computers being less powerful than a Furby?....)
He gave a detailed answer about the hypergolic fuel mixing system for the lunar module. Rather than an ignition system, they had two substances that would ignite upon contact. Instead of an electric pump, he wished he had a big simple lever to mechanically initiate mixing.
That seemed a bit odd to me at first. So, I asked if he gave that answer because it really was the most likely point of failure, or because it symbolizes a vivid nightmare – having completed the moon mission, pushing the button... and the engines just wont start.
He responded that he had dreams about that for two years prior to the launch.
At the Economist, Glenn Fleishmann writes about the 17 cameras on board the Curiosity rover on Mars. That's "seven more than any previous exploratory vehicle," he writes. They "store images in a raw, unprocessed format and initially beam back tiny thumbnails (which NASA uploads as they come in). The scientists working on different aspects of the mission meet daily to determine which of the thumbnails to download in higher resolution. The 'health and safety' of the rover takes priority. After the deliberations, which can last over an hour, instructions are dispatched to Mars." — Xeni
“At the dead hour of the night, when the world is hushed in sleep and all is still; when there is not a sound to be heard save the dead beat escapement of the clock, counting with hollow voice the footsteps of time in ceaseless round, I turn to the Ephemeris and find there, by calculations made years ago, that when that clock tells a certain hour, a star which I never saw will be in the field of the telescope for a moment, flit through and then disappear. The instrument is set; the moment approaches and is intently awaited—I look—the star mute with eloquence that gathers sublimity from the silence of the night, comes smiling and dancing into the field, and at the instant predicted even to the fraction of a second, it makes its transit and is gone. With emotions too deep for the organs of speech, the heart swells out with unutterable anthems; we then see that there is harmony in the heavens above; and though we cannot hear, we feel the ‘music of the spheres.’” — Matthew Fontaine Maury, in an 1849 presentation to the Virginia Historical Society. Maury was superintendent of the U.S. Naval Observatory.
Snip from statement of Charlie Bolden, NASA Administrator, speaking via broadcast from the Curiosity Rover on the surface of Mars: "The knowledge we hope to gain from our observation and analysis of Gale Crater, will tell us much about the possibility of life on Mars as well as the past and future possibilities for our own planet. Curiosity will bring benefits to Earth and inspire a new generation of scientists and explorers, as it prepares the way for a human mission in the not too distant future." — Xeni
This silent film clip, posted at the Smithsonian's Air & Space Magazine blog, is one of the most amazing things I've seen in a while.
First off, it shows a 1968 test run of a lunar landing research vehicle—a practice version of the lunar module that would later carry Neil Armstrong and Buzz Aldrin to the surface of the Moon. It's weird and surreal and very, very awesome to watch an LLRV rising, lowering, and swooping through the sky from the vantage point of someone standing on the ground. In general, a great reminder that we make UFOs right here on Earth.
But the real crazy bit happens at the end of the video, when Neil Armstrong—who was piloting this LLRV—bails out just before the craft plummets to the ground and explodes.
No, seriously. And it leads to this amazing story, which is, in itself, a brilliant tribute to Armstrong.
In his Armstrong biography First Man, author James Hansen recounts how astronaut Alan Bean saw Armstrong that afternoon at his desk in the astronaut office. Bean then heard colleagues in the hall talking about the accident, and asked them, “When did this happen?” About an hour ago, they replied. Bean returned to Armstrong and said, “I just heard the funniest story!” Armstrong said, “What?” “I heard that you bailed out of the LLTV an hour ago.” “Yeah, I did,” replied Armstrong. “I lost control and had to bail out of the darn thing.” “I can’t think of another person,” Bean recalls, “let alone another astronaut, who would have just gone back to his office after ejecting a fraction of a second before getting killed.”
YouTuber hahahaspam explains, "This is the Curiosity Mars Rover descent footage interpolated from ~4 frames per second to 25 frames per second. It is playing back in real time. This took me 4 days straight to put together, so I hope you enjoy it! Music: Kevin Macleod."
"He was really an engineer's engineer -- a modest man who was always uncomfortable in his singular role as the first person to set foot on the moon. He understood and appreciated the historic consequences of it and yet was never fully willing to embrace it. He was modest to the point of reclusive. You could call him the J.D. Salinger of the astronaut corps. He was a quiet, engaging, wonderful from the Midwest kind of guy... But when it came to the public exposure that was associated with this amazing accomplishment ... he ran from it. And part of it was he felt as if this was an accomplishment of many thousands of people. And it was. He took the lion's share of the credit and he felt uncomfortable with that."—Miles O'Brien, space and science journalist, speaking on CNN Saturday. — Xeni
It was a live broadcast, and there was a panel of scientists on one side of the studio, with us on the other. I was 23. The programming was a little looser in those days, and if a producer of a late-night programme felt like it, they would do something a bit off the wall. Funnily enough I’ve never really heard it since, but it is on YouTube. They were broadcasting the moon landing and they thought that to provide a bit of a break they would show us jamming. It was only about five minutes long. The song was called Moonhead — it’s a nice, atmospheric, spacey 12-bar blues.
The Educo Discovery Rocket is one of those toys I see in gift shops around the world and always think, huh, if that thing wasn't so big and unwieldy, I'd probably take it home. It's basically a nicely built doll-house shaped like a handsome modernist rocket ship. I just spotted another one and went off and read some reviews by people who own 'em, and it sounds like it holds together well, too. I'm thinking Christmas.
Neil Armstrong, the first man to walk on the moon or any other world beyond Earth, died today. The former test pilot and NASA astronaut recently celebrated his 82nd birthday, and underwent heart surgery just weeks ago.
He commanded the Apollo 11 spacecraft that landed on the moon on July 20, 1969, and radioed back to Earth the historic line, "That's one small step for (a) man, one giant leap for mankind." He walked on the moon for nearly 3 hours with fellow astronaut Edwin "Buzz" Aldrin.
He died today of complications following his cardiac surgery.
Glenn Fleishman writes in the Economist about how Curiosity sends messages home from Mars: "NASA'S Curiosity has the fastest modem on Mars. Since its only competition is an oldish bit of kit aboard Opportunity, one of two rovers dispatched in 2003, that is not saying much, at least in terms of what internet users on Earth have learned to expect. Curiosity's ability to capture images and other data easily outstrips its capacity to beam it all back home. Nonetheless, it delivers vastly more information from the red planet than any previous mission did." — Xeni
