LPSC 2011: Analysis of the grains returned by Hayabusa
I'd been despairing of finding a good source for a writeup of the presentations in the Hayabusa session at last week's Lunar and Planetary Science Conference, but am happy to report that I've finally found an excellent one.
Nick Schneider: Notes on an earthquake
I was heading south to Tokyo with Seiko and Ishi, two students from the conference. We were planning a dinner together, maybe catching the nighttime skyline from the top of Tokyo Tower. I dozed off as the train flew silently through the countryside. Next thing I knew, Seiko was shaking me awake saying
Two days from MESSENGER's Mercury arrival
Today the MESSENGER team briefed the press on the impending arrival of their spacecraft at Mercury.
LPSC 2011: Kirby Runyon on Mars, the Moon, Hartley 2, and Ganymede
Kirby Runyon, a second-year grad student at Temple University, offered to send me some writeups of selected presentations from last week's Lunar and Planetary Science Conference, and I enthusiastically agreed.
The curse of living on a geologically active planet
As the disaster of the magnitude 8.9 Sendai quake of Friday, March 11, at 05:46:23 UTC continues to unfold in Japan, I have been unable to tear my attention away.
365 Days of Astronomy Podcast: A MESSENGER to Mercury
I've got another 365 Days of Astronomy podcast airing today, this one an overview of the MESSENGER mission with particular attention to what's been learned in the three Mercury flybys, and what's going to happen when it enters orbit only a little more than three days from now!
LPSC 2011: Wanted: Pioneer 10 & 11 digital data
This is both a Lunar and Planetary Science Conference (LPSC) update and a public service announcement. Ted Stryk has been working for years to locate the original Pioneer 10 and 11 image data from the Jupiter and Saturn encounters.
LPSC 2011: Day 3: Deep Impact at Hartley 2
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.
LPSC 2011: Day 3: Moon, Mars, and Venus
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.
Pretty picture: Viking 1 across Mars
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.
Dawn Journal: HAMO2; the destination glows bright
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.
Martian timekeeping
While scanning through the talks scheduled for this week's Lunar and Planetary Science Conference I came across the following talk title:

Here are some of the noteworthy items from the morning's session on
Pretty picture: Saturn storm
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
Endeavour on Opportunity's horizon: Are we there yet?
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.
Explore the Moon in 3D through the Chandrayaan-1 TMC image data set
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.
Map the world's light pollution by participating in GLOBE at Night
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.
365 Days of Astronomy Podcast: Stardust at Tempel 1
Yesterday the 365 Days of Astronomy podcast aired my contribution, Stardust at Tempel 1: The First Second Trip to a Comet.
A Planetary Society Trifecta
A Planetary Society trifecta -- that's what Neil Tyson calls this episode of his StarTalk radio show broadcast this week. His guests include the Society's Vice President, Heidi Hammel, and its Executive Director, Bill Nye, (along with the Society's friend, Steve Squyres, Principal Investigator for the Mars Exploration Rovers).
