Скачать или смотреть Callisto's Strange Ice Towers - Most Cratered Moon Of Jupiter

This video examines the most iconic small scale feature of Callisto which are its ice towers, also known as ice knobs. I examine the evidence behind how such features form. The most likely explanation found is that they are mostly eroded crater rims. But how can things erode on Callisto's surface which is largely geologically inactive and on top of that is airless? Well, probably through the sublimation of ices along with maybe some small contribution of small meteorites hitting the surface. The images that were used in this video to piece together the puzzle of how Callisto's surface works were captured by NASA's Galileo spacecraft, however there is much more left to uncover and sadly the Juno spacecraft didn't even do a single flyby of Callisto so far.
