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.

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'

The skies aren't quite as dark as they have been, for both Spirit and Opportunity. In fact, Spirit has enough power now to be doing a little work with its robotic arm.

The dust storm continues at Mars, but both rovers continue to be power-positive.

Opportunity has ceased operations for a couple of days because the amount of sunlight available is low due to an unpredicted dust storm.

Today's set of image releases from the Mars Reconnaissance Orbiter HiRISE team included this one, of a fairly bland-looking lava plain to the northeast of Arsia Mons. Bland, that is, except for a black spot in the center.

Two months after the start of Mars Reconnaissance Orbiter's primary science phase, the Mars Climate Sounder instrument has already acquired more than four million soundings, building toward a vast data set on the three-dimensional structure of Mars' atmosphere over the full Martian year of the orbiter's nominal mission.

This amazing view was captured by the CIVA camera on Rosetta's Philae lander just four minutes before its closest approach to Mars on February 25, 2007. The spacecraft was only 1,000 kilometers above the planet.
