Teeny little Bigfoot on Mars

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:

Wheel tracks

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.

Opportunity takes first gingerly steps into Victoria Crater

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.

Dust storm update: A rover's-eye-view

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'

Mimas, Dione, Rhea

There's been quite a lot of Mars on this page for the last week; it's time to remind ourselves that there are other places besides Mars in the solar system.

Many Cassini views of Tethys

Here we bring you fifteen different Cassini views of the same world, a cratered ball of ice called Tethys.

Io erupts, in color

The last one of New Horizons imaging instruments has finally checked in with a lovely image from the Jupiter flyby

Cassini's global views of Saturn and its rings

Since late January Cassini has been acquiring several sets of images that show all of Saturn's globe and ring system at once from perspectives well above and below the ring plane.

New Horizons sees Io erupting!

There were two new pictures posted on the New Horizons Science Operations Center website this morning, of Io, and if you enhance the images a bit, there are two clear volcanic plumes visible on the limb -- Tvashtar and Prometheus are active!

Saturn from above, in color

I wrote recently about a set of images of Saturn acquired by Cassini from a unique vantage point, well above the planet, looking down on the rings. Someone has taken up the challenge of assembling the 36 different images into a single mosaic, in color, and it is as lovely as I'd hoped.

New Horizons' raw images are now online

I got an email from John Spencer this morning telling me that the mission had posted all of New Horizons' most recently acquired images on the mission website.

The Saturn view I've been waiting for

Over the weekend, Cassini acquired a set of images that will (I am assuming) eventually be used to produce a glorious portrait of the ringed planet from a point of view that's never been seen before.

Cassini's view from the backside of Saturn

Over time, Cassini's orbit apoapsis—the point on the orbit that is farthest from Saturn—has been shifting slowly toward Saturn's night side. Lately, this point of view has resulted in some truly lovely photos of the planet.
