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
It's a legal holiday here in the U.S. (President's day), and my daughter's babysitter is taking the day off, so I won't be getting much work done today. But I thought I'd check in to share the fact that, as we got out of the car last week, my daughter pointed up in the sky at the crescent moon and said "Dat!" so I gave her the word, "Moon."
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.
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: "Is it a rock? A trick of Martian light on the eye? Or Osama Bin Laden waving from his barren hideout 300 million miles from planet Earth?")
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.
