I heard about a peak on Iapetus that may be taller than Olympus Mons on Mars. I was wondering if the RADAR instrument will be used in the January encounter to verify this. What is the maximum distance the RADAR can be used?

Jason's stretched image makes it clear that Iapetus' irregular limb -- whioch ahs always intrigued me -- is due to the simple fact, that, for whatever reason, this moon has had the living hell bashed out of it. That largest impact basin looks like the hugely oversized craters that NEAR photographed on the asteroid Mathilde. Is it possible that -- as an abstract I recently saw suggests -- Iapetus is a captured moon, like Phoebe (and Triton)? This could explain its moderately tilted orbit.
