As I post this, NASA is holding a press conference in which they are announcing that the Mars Science Laboratory's launch date will be slipped by two years.

At 12 noon EST. I know what the announcement is, but I'm not allowed to tell you! How frustrating is that?!

Mike Griffin started the press conference, and got right down to business announcing the launch delay and indicating that the actuators as well as other technical problems are responsible.

The rest of ANSMET's team are in Christchurch after a long, long session of travel.

I just heard, via this article at Universe Today, that the sample cache on MSL has been canceled.

The period of Mars solar conjunction has just begun, which means that a host of scientists and engineers whose day jobs entail interaction with the five active Mars spacecraft are getting a five-week break from the daily grind of operations.

I've known about this for a little while but it was finally made public: The list of MSL landing sites had now been trimmed to four.

There was a worrying update posted on the JPL website for Spirit today: an early-season dust storm has darkened its skies enough that its solar panels produced only 89 watt-hours of power yesterday, sol 1,725. Neither rover has ever, ever seen power production levels that low, not even during last year's massive dust storm.

Another day, another drive: on sols 1,693 and 1,695 the Opportunity rover conducted two more lengthy drives to the south, totaling almost 200 meters. On the other side of the planet, Spirit is FINALLY in motion again.

When MESSENGER flew past Mercury for a second time on October 6, 2008, its cameras snapped photos of an impressive 30 percent of the planet's surface that had never previously been seen by spacecraft.

Victoria crater, the site of a Mars year's worth of study, is now far over the horizon, as Opportunity has lately completed a series of very long drives. Opportunity is once again sailing the sand seas of Meridiani Planum.

An article in the September 26 issue of Science neatly explains why only the southern half of Mars is strongly magnetized.

Last week, the Mars Odyssey team announced that their mission is being extended another two years. This mission extension will be slightly different from previous mission phases due to a planned change in the spacecraft's orbit.

This time around DPS features three separate oral sessions on Titan, indicating just how much attention that moon is getting from the scientific community right now. From the first session, on Titan's lower atmosphere, I'm just covering the two talks on Titan's lakes.

NASA is holding a press conference right now regarding MSL and it sounds like they are going to press on and try to achieve the October 2009 launch date.

It's been way, way, way too long since the view from either rover's cameras has changed very much. So I hope you'll join me in a shout of
