allen stern has worked with simon porter predicting what this will do. they had a prediction paper but jeff, the geologists will look at the geometry and tell us what happens. jeff: i am still having to remind myself to take the wraps. deck -- take deep breaths. the landscape is astounding. let's go back to this picture we talked about a few days ago and remind us that the global view shows us the surface of pluto is peppered with craters, where as other regions such as the heart showed no craters at all. that is obviously younger and indicate that pluto has experienced a long and complex geological history. this means there active land creating processes operating in the geo current tide. some of the craters appear partially destroyed, perhaps by erosion. there are also parts of pluto's crust that have been fractured indicating some forms of tectonics. there are mountain building forces operating on pluto. also some of the higher resolution images show that there are craters which may have been partially eroded away so he rose and processes also seem to be -- erosion processes also seem to
