The Cassini spacecraft flew by Saturn's moon Titan on Tuesday, and in this case both optical and smog-penetrating radar instruments were trained on the same region of the planet. The combined effort revealed the only crater, a very large one , yet seen on Titan. The crater walls are heavily "weathered" with whatever is going on in Titan's atmosphere.
You can see pictures of the crater at the ESA site here , and a nice write-up at Wired is here.
The Eyrie also has a very interesting rumor about some new Mars observations. Go have a look. Now, where are my hiking boots?
