Sturzstroms on Saturn's Moon Iapetus

Posted by Kelsi Singer on 2012/10/01 04:31 CDT

Long-runout landslides (sturzstroms) are found across the Solar System. They have been observed primarily on Earth and Mars, but also on Venus, and Jupiter’s moons Io and Callisto. I have just published a paper about sturzstroms on Iapetus.

More radar images of icy moons from Cassini: Iapetus, Enceladus, and Rhea

Posted by Emily Lakdawalla on 2011/12/21 12:10 CST

When I posted about the really cool Cassini SAR images of Enceladus a few weeks ago, I initially wrote that this was the first-ever SAR image of an icy moon other than Titan. Several people (some readers and two members of the Cassini science team!) corrected that statement: Cassini has performed SAR imaging of other icy moons (including Enceladus) before.

Showing off Saturn's moons

Posted by Emily Lakdawalla on 2008/02/19 04:40 CST

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
