Martian Carbon...

Curiousity - AAAS Science Mag
SAN FRANCISCO, CALIFORNIA—The first full analysis of martian soil by the Curiosity rover has detected simple carbon compounds that could be the first traces of past martian life ever found, NASA scientists announced here today at a press conference at the annual fall meeting of the American Geophysical Union. The catch is that Curiosity team members can't tell yet whether the organic matter was once alive, was never alive and drifted onto Mars from space, or was simply cooked up in Curiosity's analytical instrument from lifeless bits of soil. Figuring out the ultimate source of the carbon in this organic matter—biological or not—will take time. "Curiosity's middle name is Patience," cautioned Curiosity project scientist John Grotzinger of the California Institute of Technology in Pasadena.

SAM's the Word...

Happened on Tuesday. Hopefully, an interesting Christmas present.

For a rip: they should announce conclusions December 21st. The world would poetically "end as we knew it."

NASA's Mars rover Curiosity dug up five scoops of sand from a patch nicknamed "Rocknest." A suite of instruments called SAM analyzed Martian soil samples, but the findings have not yet been released.

NPR: Scientists working on NASA's six-wheeled rover on Mars have a problem. But it's a good problem.

They have some exciting new results from one of the rover's instruments. On the one hand, they'd like to tell everybody what they found, but on the other, they have to wait because they want to make sure their results are not just some fluke or error in their instrument.

It's a bind scientists frequently find themselves in, because by their nature, scientists like to share their results. At the same time, they're cautious because no one likes to make a big announcement and then have to say "never mind."

The exciting results are coming from an instrument in the rover called SAM. "We're getting data from SAM as we sit here and speak, and the data looks really interesting," John Grotzinger, the principal investigator for the rover mission, says during my visit last week to his office at NASA's Jet Propulsion Laboratory in Pasadena, Calif. That's where data from SAM first arrive on Earth. "The science team is busily chewing away on it as it comes down," says Grotzinger.

One Small Step...

PASADENA, Calif. -- NASA's Curiosity rover mission has found evidence a stream once ran vigorously across the area on Mars where the rover is driving. There is earlier evidence for the presence of water on Mars, but this evidence -- images of rocks containing ancient streambed gravels -- is the first of its kind.

Scientists are studying the images of stones cemented into a layer of conglomerate rock. The sizes and shapes of stones offer clues to the speed and distance of a long-ago stream's flow.

"From the size of gravels it carried, we can interpret the water was moving about 3 feet per second, with a depth somewhere between ankle and hip deep," said Curiosity science co-investigator William Dietrich of the University of California, Berkeley. "Plenty of papers have been written about channels on Mars with many different hypotheses about the flows in them. This is the first time we're actually seeing water-transported gravel on Mars. This is a transition from speculation about the size of streambed material to direct observation of it."

“Nothing in the world is more flexible and yielding than water. Yet when it attacks the firm and the strong, none can withstand it, because they have no way to change it. So the flexible overcome the adamant, the yielding overcome the forceful. Everyone knows this, but no one can do it.”

The Next Phase...


We set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people. For space science, like nuclear science and all technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of pre-eminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war. I do not say that we should or will go unprotected against the hostile misuse of space any more than we go unprotected against the hostile use of land or sea, but I do say that space can be explored and mastered without feeding the fires of war, without repeating the mistakes that man has made in extending his writ around this globe of ours.

There is no strife, no prejudice, no national conflict in outer space as yet. Its hazards are hostile to us all. Its conquest deserves the best of all mankind, and its opportunity for peaceful cooperation many never come again. But why, some say, the moon? Why choose this as our goal? And they may well ask why climb the highest mountain? Why, 35 years ago, fly the Atlantic? Why does Rice play Texas?

We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.

President John F. Kennedy

I was a year and almost a month old when these words were spoken. They stir emotion, excitement and vision; hope and direction. As I read them for this post, I wept quietly.

"...not because they are easy, but because they are hard..."

It was not advanced robotics and transistorized super computers that allowed Mercury, Gemini and Apollo: it was grit, sweat, and knowledge of how to compute with a slide rule. It was during a time of social upheaval, physical and brutal de facto segregation and the struggle for Civil Rights. It was during an era a short-lived cancelled show - Star Trek - which later became a cult phenomenon in that we might actually survive the dark corollary of the Drake Equation. It was before our politicians became more concerned with job security than problem-solving; speaking-to-the-base in soundbite talking points versus reaching consensus. It was before a cottage industry of standardized testing gave us fifty inane yardsticks without a national standard but a nebulous goal birthed of sloganeering: No Child Left Behind (or, No Child's Behind Left).

It was before our answers had "Google" in the lexicon; post "Sputnik moment" of fear turned inspiration, when we plunged head long with only one driving directive:

We Are Earthlings...

Curiousity Rover: NASA
NASA: Curiosity, the car-size, one-ton rover is bound for arrival on Mars at 1:31 a.m., EDT on Monday, Aug. 6.

The landing will mark the beginning of a two-year prime mission to investigate one of the most intriguing places on Mars.

Curiousity has landed!
