Though it makes sense to use the same designs again, saving money, I must admit a personal lack of excitement about this announcement. First, I have doubts it will fly because of the federal government’s budget woes. Second, it is kind of a replacement for the much more challenging and exciting missions to Titan and Europa that the Obama administration killed when they slashed the planetary budget last year.
The press lets Curiosity get the better of them
The big news is out. Today the eagerly awaited press conference at the American Geophysical Society meeting in San Francisco on the recent results from the Mars rover Curiosity was finally held. The announced results had been hyped like crazy when rumors began to spread a few weeks ago that Curiosity had discovered something truly spectacular.
Well, here are some of the headlines heralding the results.

NASA is downplaying the hype about a big discovery by Curiosity.
Surprise, surprise! NASA is downplaying the hype about a possible big discovery by Curiosity.
As I noted, Curiosity might have found something that is interesting and exciting, but every news source that hyped this story deserves criticism. Good journalism is reporting the news, not speculating about something that hasn’t happened yet.

Has Curiosity made a big discovery?
There has been a lot of buzz the past twenty-four hours about the possibility of a major discovery from Curiosity. However, I agree with Jeffrey Kluger at Time. It is dangerous to pay much attention to these wild speculations, as they are often wrong. Stay calm, and wait for some real information. The most likely possibility is that they have found something very intriguing and exciting, but not Earth-shaking.

An older rover releases a picture
Scientists have released a spectacular panorama taken by the now dead rover, Spirit, from its perch at its 2006 winter haven. I have posted a cropped section of that panorama below the fold, with some analysis.

The first results from Curiosity’s soil samples have come back.
“Much of Mars is covered with dust, and we had an incomplete understanding of its mineralogy,” said David Bish, CheMin co-investigator with Indiana University in Bloomington. “We now know it is mineralogically similar to basaltic material, with significant amounts of feldspar, pyroxene and olivine, which was not unexpected. Roughly half the soil is non-crystalline material, such as volcanic glass or products from weathering of the glass. ”
Bish said, “So far, the materials Curiosity has analyzed are consistent with our initial ideas of the deposits in Gale Crater recording a transition through time from a wet to dry environment. The ancient rocks, such as the conglomerates, suggest flowing water, while the minerals in the younger soil are consistent with limited interaction with water.” [emphasis mine]
These results suggest that there has been very little water on the Martian surface for a very long time. They do not, however, mean that there is no water there now.

The mysterious shiny particles uncovered by Curiosity’s scoop are from Mars, not the rover.

After last week’s plastic encounter, Curiosity’s science team worried the new particles might be man-made. Since they turned up in scoop holes, however, the granules must have been buried in the subsurface. They likely came from larger minerals that broke down. They might also represent the product of some geological soil process that generates a bright but unknown mineral.
These are not the same mysterious objects first seen when the rover began science operations. Those particles were on the surface, and looked like bits of plastic that might have come off the rover or its descent stage.

“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.”
This discovery also confirms the wisdom of Gale Crater as a target. Satellite data and images had suggested the crater had once been water filled. Now this suggestion appears confirmed.
