NASA has put together a nice movie of Dr. Mike Mumma summarizing his discovery of methane on Mars.

I got an urge to dive in to the Voyager image archives and see what exactly we have here on Earth to base our understanding of the Uranian moons on.

Tonight at the Boston Court Performing Arts Center in Pasadena, Jim Bell and Bill Nye will be celebrating the 5th anniversary of the landing of the rovers; Jim will be showing lots of pretty 3D pictures.

A tip of the hat to Ryan over at Martian Chronicles for posting this lovely version of the Santorini panorama, which Opportunity captured just before Mars dipped too close to the Sun in late November of last year.

Hallelujah! For the first time in almost an Earth year, amateur mars mapper Eduardo Tesheiner is able to scratch a tiny little line on his map of the Mars Exploration Rover Spirit's peregrinations across Gusev Crater.

Scott Maxwell is one of those many guys (and gals) at the Jet Propulsion Laboratory who rarely gets his name in the news but who is absolutely indispensable to the success of a space mission. I don't know what his official title is, but whatever it is, it's not as good as the colloquial name given to his position: Rover Driver.

Having fulfilled all of its assignments for 2008, the Dawn spacecraft has been unusually quiescent recently.

On January 3, 2004, the Mars Exploration Rover Spirit landed on Mars, and I was with the science team at JPL when it happened! I can't believe it's been five years since the successful landing.

A very pretty picture of a moon among stars. Happy 2009, everyone!

As 2008 fades to the pages of history, Spirit and Opportunity are closing in on the end of their fifth year of exploration on the Red Planet and moving the Mars Exploration Rover mission forward into a new year of bold scientific objectives.

We're getting close to the fifth anniversary of the landings of Spirit and Opportunity, but was we approach that milestone, we're passing another. I've been told that as of yesterday, Spirit and Opportunity have operated on Mars for a combined length of time that is longer than the combined number of sols that the twin Viking landers operated.

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.

Ryan Anderson

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 Dawn spacecraft is healthy and on course for its flyby of Mars early next year. The planet's gravity will help boost the probe on its way to rendezvous with Vesta.

The Mars Exploration Rovers are nearing the end of their fifth year of exploring the Red Planet in dramatically different ways.

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.

Ryan Anderson

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.

I am greatly relieved to report that Spirit did talk to Earth as ordered today, indicating that the rover's power situation did not get so bad that a
