1 Extraterrestrial Life: Spring 2008 Enceladus Small (~500 km diameter) moon of Saturn - orbits between Mimas and Tethys Two distinct hemispheres: • northern is quite heavily cratered (old) • southern shows almost no craters across wide area Albedo is almost 100% - icy surface must be very freash Extraterrestrial Life: Spring 2008 Enceladus north pole as views by Cassini during last week s flyby of the satellite. Extraterrestrial Life: Spring 2008 Enceladus orbits within, and appears to be the source of, Saturn s faint E ring. Ejects icy particles into the ring, some of which are later re-accreted by the satellite (note: ring particles are fully exposed to sunlight, so chemistry can happen driven by this exposure). Extraterrestrial Life: Spring 2008 Surface of Enceladus that is devoid of craters resembles Europa - appears to have tectonic activity Extraterrestrial Life: Spring 2008 Surface of Enceladus that is devoid of craters resembles Europa - appears to have tectonic activity

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
