The latest HiRISE images of the Phoenix polar lander, taken near Mars' northern summer solstice, show why we haven't heard from the spacecraft since it fell silent on November 2, 2008: it appears the solar panels have collapsed.

I wrote some time ago about the expectations for the Wide-field Infrared Survey Explorer (WISE)'s contributions to solar system science. A couple of days ago, JPL posted an image and movie documenting the progress to date.

As I discussed on Monday, Opportunity is in the middle of a lengthy trek toward a crater named Endeavour and its tantalizing upraised smectite-bearing rim.

Exploring Earth analogues of space landscapes is a valuable activity that can help planetary scientists correctly interpret what their instruments are telling them.

Opportunity's kilometers-long march across the sands of Meridiani Planum is a great story, and the journey is fun to follow; but what could be worth such a long march?

Three of Akatsuki's six science instruments have now checked in as operating normally, producing lovely photos of the receding homeworld.

Every time I think Cassini has captured the coolest image of Enceladus ever, it does better.

Cassini flew within 436 kilometers of Enceladus' surface today. Although it's Cassini's 11th targeted flyby of Enceladus, these close buzzes are never routine.

This image, released today by Cassini's imaging team, is pretty cool; it shows one of Saturn's larger moons together with one of its smaller ones. I probably noticed the nice photo of Dione when it appeared on the Cassini raw images page two months ago, but I know I didn't notice the little speck below and to the left of the bigger moon. That speck is a small moon, Telesto.

Coming closer every day, Mr. Hayabusa has sighted his final destination: his homeworld, Earth, and its attendant Moon.

It's the solstice on Mars today: summer in the north, winter in the south.

Every time Cassini gets reasonably close to one of the moons of Saturn, whether the close approach is a targeted one or just an opportunistic encounter, its planners usually take advantage of the proximity to take a bunch of photos.

Through a crazy random happenstance, I was just interviewed by a friend of a friend of a friend at Australian radio station 'triple j' for a feature on lasers!

I'm delighted to point you to a citizen science project for wannabe space geologists like me: Moon Zoo.

Wow, this is a cool paper. Here's the gist: the Cassini RADAR team has spotted some river channels on Titan that shine so brightly in radar images, there must be something special going on to explain that brightness.

Via Daniel Fischer's Tweet about a blog entry by Astro BobI learned of something which should be obvious to anyone who has trained even a rather small telescope on Jupiter over the past few weeks: one of its iconic stripes is just plain gone.

On Mars, at 15:00 local true solar time on May 2, a solitary rover gazed southward across her own dusty deck and snapped three photos, actually three sets of three photos, which were combined to make this view.

A recent entry by Bethany Ehlmann from the blog of the Planetary Geomorphology Working Group of the International Association of Geomorphologists demonstrates how you can combine the power of different types of data to tease out a rich story of the past history of one spot on Mars.
