Video Simulations of Impact Cratering Processes


The LPI-JSC Center for Lunar Science and Exploration has prepared a series of video simulations of impact cratering processes for classroom use. The videos explore how impactor size and velocity, as well as target gravity and temperature, affect the sizes and morphologies of impact craters.  The videos can be run in real time from the website or, if users prefer, downloaded to their own computers.

United States Topo Maps


United States Topo quadrangles are digital topographic maps produced by the National Geospatial Program of the US Geological Survey (USGS). Created in the familiar 7.5-minute quadrangle format like the legacy paper maps, US Topo maps support frequent updating, wide and fast public distribution, and basic, on-screen geographic analysis. US Topo maps are available for free Web download from the USGS Store.
