Over the last couple of days Cassini flew past Enceladus, Tethys and Dione, so there are lots of treats to see on the raw images website! You should go check it out for yourself, but here are a couple of real favorites.

It never ceases to amaze me how much science is being wrung out of the few grams of material that were returned to Earth by the Stardust mission.

You know, I could fill this blog almost entirely with the amazing images that Gordan Ugarkovic locates, processes into prettiness, and uploads to his Flickr account.

I've posted animations from Cassini before in which there are multiple moons moving around, but this is one of the coolest such sequences I've seen yet.

Acidalia Planitia is a large basin in Mars' northern lowlands, a dark splotch visible even from Earth telescopes.

I've spent a pleasurable hour or so browsing over the latest release of images from Cassini to the Planetary Data System.

Winter lingers in the southern hemisphere of the Red Planet, but the Sun is beginning to rise higher in the sky and temperatures are slowly rising, signs the Mars Exploration Rovers are heading into spring. While Spirit continued hibernating, Opportunity took in the warmth of the Sun, captured its first dust devil, and picked up the pace in Meridiani Planum on the long journey to Endeavour Crater. Together, the rovers marked six and a half years of exploration.

Well folks, I'm headed off to Big Sky Country tomorrow (aka Montana)! I'll start the week at the MSL camera team meeting, where I will get all sorts of cool news about the MastCam, MAHLI and MARDI cameras which I will not be able to share with you.

Spirit hasn't talked to Earth since March 22 -- so what new information could they have received that would make them pronounce Spirit's possible death? Is there some new analysis of the last bit of telemetry? Some new model indicating Spirit's survival was less likely than previously thought?

I'm a little late on this, but I thought I should share the news: MSL now has a good head and neck on its shoulders, and has officially

Dawn is flying smoothly through the asteroid belt, now less than a year from entering orbit around Vesta, the first of its two cosmic destinations.

This news is no surprise, but I think it's the first such discovery I've heard of: the Lunar Reconnaissance Orbiter Camera (LROC) team has identified a new crater on the Moon, one that wasn't there when Apollo 15 flew over.

Three years after New Horizons flew past Jupiter on its way to Pluto, the spacecraft has imaged the giant planet again.

Here are two newly processed portraits of Saturn, showing the planet just after its equinox.

During Friday's first roll for Curiosity, there was a lot of banter in the Ustream chat room about all the bunny-suited engineers waving at the cameras and mugging for portraits with the rover. One chat room member,

While we were in New York for the International Solar Sailing Symposium last week, we held a meeting with the Japanese IKAROS team to discuss technical results and issues in our two projects.
