Just two weeks after MESSENGER's first flyby of Mercury, the mission's science team presented their first impressions from the long-awaited second look at the innermost planet.

The story of a Sasquatch-shaped rock visible in a recent panorama from Spirit is getting a lot of play in the mainstream media, but fortunately, it's not being taken very seriously. (My favorite take on this picture is the lead from the Times Online story about it:

On the evening of Tuesday, January 15, the MESSENGER science team crowded around a computer screen, anxiously awaiting their first view of the previously unseen hemisphere of Mercury.

One of the major results from the Cassini mission last year was the production of a mosaic of images from its RADAR instrument covering Titan's north pole. Titan's north pole has lakes upon lakes, some big, some small, but everywhere you look, there they are.

Mercury scientists' very long wait for new data from a spacecraft at Mercury will finally come to an end on Monday, when MESSENGER makes its first close approach to the innermost planet.

Antares dims and brightens as it passes behind the rings as seen from Cassini in this animation.

Dust from the sky has settled on both the rover deck and the surrounding landscape. The dust-covered solar cells will not be able to generate as much power as when they were clean. Unless a puff of wind dusts off the solar panels, Spirit may have difficulty surviving the approaching Martian winter.

It hasn't been that long since the Mars Science Laboratory landing site downselection meeting; it was quickly followed by a meeting in Europe on ExoMars, which is currently planned for a 2011 launch.

A couple of days ago Malin Space Science Systems (MSSS) issued a news notice that explains some of the horse-trading that went on behind the scenes to rescue MARDI, the descent imaging camera that they are building for the Mars Science Laboratory rover.

Unlike the Mars Exploration Rover mission, which featured two golf-cart-sized landers, this time we have only one giant, Volkswagen beetle-size. So at the end of this process we have to pick our favorite place on Mars, not our favorite two places.

The Mars Exploration Rovers have left wheel tracks all over their landing sites, but for some reason this pair of wheel tracks, left in the sand ripple on the rim of Victoria crater and now viewed from below, tickled my fancy. Thanks to James Canvin for the lovely panorama.

Lakes have been spotted near the south pole of Titan before, in this image by the ISS team, which was considered compelling but not conclusive at the time.

Mars Exploration Rover scientists, engineers and enthusiasts have been playing the waiting game for 10 weeks, watching the much-reported dust storm subside so that Opportunity could get back to doing what it does best - exploring craters.

Although Mars' atmosphere continues to be rather dusty, the storm has abated enough that both Mars Exploration Rovers have resumed a relatively normal level of activity. For Opportunity, that means a drive to the very edge of Victoria crater.

I haven't written an update on the dust storm at Mars recently for two reasons. For one, the rovers are out of immediate danger, so it wasn't as urgent. The other reason is that Jim Bell wanted Cornell to issue a press release with updated versions of the images and animations I've been putting together from the rovers'
