I thought that today's image release from the Cassini imaging team was exceptionally pretty.

The HiRISE instrument on Mars Reconnaissance Orbiter really is a spy camera in space. Check out this sequence of nine images from the HiRISE archives, which Doug Ellison pulled together into an animation covering more than a year of Spirit's mission.

In the fourth installment in my look at one spot on Mars as seen through the eyes of different spacecraft, we finally get to a mission that is still operational: 2001 Mars Odyssey.

We first spotted the strange bright feature colloquially known as

There was a press release from the Cassini mission today about a pile of papers (14 of them!) being published in the journal Icarus about Saturn's icy moons. I haven't had time to read more than the overview article yet, but I wanted to come up with a graphic for an overview of Saturn's moons, and I couldn't resist delving into the massive database of Cassini images to produce something new

This is the second installment in my look at one enigmatic feature on Mars as seen by all its orbiters through the more than thirty years of spacecraft observations.

Opportunity is now following a rather leisurely autumn schedule, according to the latest update on the mission website. Some of the work Opportunity is doing involves staring skyward, looking for patterns in the clouds that pass overhead at this time of year. One of the guys at unmannedspaceflight.com has put together some nifty animations of the wispy cloud patterns.

While conversing with Ken Edgett about the smiley face on Mars he remarked to me how different Mars looks at different pixel scales, and in particular that there is a transition somewhere in the neighborhood of six to seven meters per pixel.

I thought this was a fun image to kick off the weekend. This isn't the first happy-looking crater to be photographed from Mars, but I really like this one; it's more goofy.

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:

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

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.

At 7:34 a.m. EDT the Delta II Heavy roared off launch pad 17 B at Cape Canaveral with a brilliant flash of glowing orange light and billowing white smoke.

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.

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'

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.

The other day I posted a global view of Titan featuring new territory near the north pole. Now the imaging team has released a much higher resolution version of this view.

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