Wednesday morning included some interesting conversations. Notably, I spoke with Pamela Gay, who is responsible for the MoonZoo citizen science program and who is presently working on developing a site through which the public will be able to help search for potential Kuiper belt objects for the New Horizons mission to encounter after the Pluto flyby.

Wednesday's sessions at the Lunar and Planetary Science Conference (LPSC) on the Deep Impact flyby of Hartley 2 were one of two that I was most looking forward to, the other being this morning's talks on Hayabusa's samples from Itokawa, about which I don't yet have any notes. I am again grateful to Franck Marchis and Andy Rivkin for sending me their notes on Hartley 2.

While scanning through the talks scheduled for this week's Lunar and Planetary Science Conference I came across the following talk title:

Image magician Daniel Macháček has been turning his energies to Viking Orbiter views of Mars lately, with some stunning results, like the one below. I'm not sure how he makes images that look so sharp and clean and with such rich color out of the Viking Orbiter data.

Deep in the asteroid belt, Dawn continues thrusting with its ion propulsion system. The spacecraft is making excellent progress in reshaping its orbit around the sun to match that of its destination, the unexplored world Vesta, with arrival now less than five months away.

To relieve this week's text-heavy LPSC posts, here's a brief one on an incredible panorama across Saturn's northern storm, taken on February 26 by Cassini and assembled by unmannedspaceflight.com member

Science is all about asking questions, coming up with ideas that might explain the answers, and then poking at those ideas to see if they work. Scientists spend much of their time in solitary research working out those ideas. But they also devote big chunks of time to meetings where they pitch their ideas and see what their peers think of them.

The first full scale deployment of the Planetary Society's LightSail 1 solar sail was conducted on March 4, 2011 at Stellar Exploration in San Luis Obispo, California.

Another painful loss to NASA's mission to study Earth from space: Today a Taurus XL rocket failed to lift the Glory satellite into Earth orbit when its clam-shell nosecone refused to open, forcing the rocket and its payload into the southern Pacific Ocean.

The Lunar and Planetary Science Conference is happening next week. The sessions and abstracts are all in PDF format, so it's tiresome to access them online; I much prefer to download them all to my computer and browse them locally.

In my last couple of posts about the Stardust spacecraft, which is now basically out of fuel after a remarkably successful extended mission to comet Tempel 1, I've mentioned that it's soon to be decommissioned. A reader asked me: what does it mean to decommission a spacecraft?

Last week the Mars Exploration Rover team dumped another 90 sols' worth of data from Mars into NASA's Planetary Data System, the national repository for space mission data. As I did once before, I dove into this fresh pile of data to pull out Opportunity's color views of the distant rim of Endeavour crater.

Data from two of the cameras aboard Chandrayaan-1 are now available through the ISRO Science Data Archive (ISDA), a new(?) site that is being established to host the data from ISRO's deep-space missions.

Now in its sixth year, GLOBE at Night is a citizen science program that marshals the eyes of thousands of people around the world once a year to assess the degree to which light pollution diminishes our views of starry skies.

I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).

Yesterday the 365 Days of Astronomy podcast aired my contribution, Stardust at Tempel 1: The First Second Trip to a Comet.

Are you concerned about the future of women in science? Well, you should be, since the women working in science today and tomorrow will help shape the world you live in.
