Thanks to the work of several amateurs, Google Mars is a great tool for following the past and future peregrinations of the Mars Exploration Rover Opportunity.

Last week we got buzzed by a very small asteroid, something that happens fairly often. But there were several details that made the close approach of asteroid 2011 CQ1 worthy of note.

There is a huge storm that's spreading across so much of Saturn that it's been readily visible even from Earth-based telescopes. Over the past couple of days a couple of new images of Saturn have appeared that show just how enormous the storm is today.

Today Mars made its closest approach to the Sun -- as seen from Earth, that is. Why is this important?

Dawn continues its flight through the asteroid belt, steadily heading toward its July rendezvous with Vesta, where it will take up residence for a year. On January 10, Dawn performed some of the activities that it will execute in its low altitude mapping orbit (LAMO) at Vesta.

I wasn't able to watch the Kepler press briefing today so I will give you links to some of my favorite blogs for information on today's announcement, which follows a major data release last night as well as the publication of a paper in Nature.

Here's an image I've been meaning to post for months, a new mosaic from Voyager 1 by Ted Stryk of Io crossing Jupiter's terminator as it neared closest approach.

In the past week there have been 25th anniversaries of two events in 1986, one great, one terrible: the closest approach of Voyager 2 to Uranus on January 24, and the explosion of the space shuttle Challenger upon liftoff on January 28.

I've spent the day noodling around in the current issue of Icarus, following up some of the more interesting stories within its table of contents, and came across a picture of this very cool crater -- actually, set of craters -- on Mars.

It is with great relief that I now report that JPL announced this evening the sighting of Tempel 1 by Stardust, a mere month before the planned flyby.

Daniel Macháček has colorized some terrific images of Phobos and run them through some morphing software to make a seamless animation that appears to show Phobos rotating before you.

A new update has been posted to the Stardust website: The spacecraft continues to operate as expected and all subsystems are healthy on approach to comet Tempel 1.

The Mars Express High-Resolution Stereo Camera (HRSC) team has just released several images from the most recent series of Phobos flybys to the Mars Express blog.

Daniel Macháček has reached into the dark side of Prometheus and pulled out an incredible amount of detail where the potato-shaped moon is illuminated by Saturnshine. He produced an animation that morphs among the three sets of four-filter color images that Cassini snapped during the flyby.
