While I work on my blog post about debris flow, I thought I’d put an awesome image of one of Saturn’s moons, Mimas. This image was taken by none other than the supremely talented Cassini team over at JPL. Visible in this image is the impact crater, Herschel. Coming in at 130 km across and 10 km deep, it’s one of the more prominent craters in the Solar System. In fact, that great font of knowledge, Wikipedia, even suggests that if “there were a crater of the same scale on Earth, it would be wider than Canada”. Herschel may not be the largest impact crater, (that honor goes to the North Polar Basin on Mars), but for it’s size in proportion to the parent body, it’s no slouch either.  And if you haven’t done so yet, I highly recommend visiting the raw images on the Cassini website. Sometimes you can find some really great pictures that don’t always make it into the popular science sites.
