Cassini's doing Iapetus encounter science now

Phoenix returns its first photo
Phoenix is cruising to Mars, on its way to a landing in May of next year. And it's now returned its first photo from the cruise. Most of the time, when a Mars spaceship returns its first photo, you expect to see a tiny dot amidst a field of stars,... More»

Another approaching view of Iapetus
This morning I found four more Iapetus frames on the Cassini raw images website, captured from a third closer to Iapetus than yesterday's post. Here's that picture, which I produced the same way I described yesterday. You can see a little bit more... More»

Cassini's approaching view of Iapetus
I don't believe I'm going to get my Iapetus preview story in the shape I want it to be in time to post it today, but I thought you might enjoy seeing this image as a bit of a teaser. Cassini took the images for this photo from a distance of about... More»
