Dawn continues to close in on Mars, ready for the gravitational slingshot that will help it on its expedition to the asteroid belt and its quest to gain insights into the evolution of the solar system.
There's more to the Hayabusa story
After posting my brief
Hooray for Hayabusa!
According to JAXA (the Japanese space agency), poor little Hayabusa has successfully restarted its ion engine and has resumed powered flight today. Hooray! This is good news for Hayabusa's eventual return to Earth.
Spirit update: It keeps going
There have been a couple more releases from JPL in recent days updating the slightly worrisome announcement about Spirit that came out on January 28.
New Google Mars
Google Earth's latest edition was just released and guess what? It has a Mars setting!
A pretty new Hubble image of Mars
A set of Mars image data taken by the Hubble Space Telescope a year ago was just released to Hubble's data archive. It was captured by Hubble's Wide Field and Planetary Camera 2 on January 30, 2008 when Mars was about 115 million kilometers from Earth.
Mars Exploration Rovers Update: Spirit and Opportunity Begin Sixth Year of Exploration
The Mars Exploration Rover mission crossed the finish line of another major milestone this month, marking its fifth anniversary of exploring the Red Planet. As team members celebrated and shared stories in events all around Los Angeles, Spirit and Opportunity kept on roving, bucking up under the inevitable pains of growing older. They're heading now for their next major destinations.
Dawn Journal: Just Missing the Bull's Eye at Mars
Dawn continues on course for its pas de deux with Mars on February 17. The planet's gravity will gracefully assist the spacecraft on its way to rendezvous with its intended celestial partners Vesta and Ceres in the more distant asteroid belt.

Rather than try to interpret what's going on, I'm just going to repost in full a

What are the rovers up to? January 2009
Spirit's been getting some nice views of the spot it spent all of 2008 in,
What do we know about Uranus' moons? Part 1
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.
Mars Methane Movie
NASA has put together a nice movie of Dr. Mike Mumma summarizing his discovery of methane on Mars.
Some events for the 5th anniversary of Spirit and Opportunity's landing on Mars
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.
The Santorini panorama
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.
Spirit moved!
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.
I am totally hooked on Scott Maxwell's new Mars Exploration Rover blog
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.
Dawn Journal: Conjunction Junction
Having fulfilled all of its assignments for 2008, the Dawn spacecraft has been unusually quiescent recently.
Five Years of Spirit on Mars
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.
