  NASA's Meteoroid Engineering Model (MEM) is designed to provide aerospace
engineers with an accurate description of potentially hazardous meteoroids. It
accepts a spacecraft trajectory as input and its output files describe the
flux, speed, directionality, and density of microgram- to gram-sized meteoroids
relative to the provided trajectory. MEM provides this information at a fairly
fine level of detail in order to support detailed risk calculations. However,
engineers and scientists in the very early planning stages of a mission may not
yet have developed a trajectory or acquired the tools to analyze environment
data. Therefore, we have developed an online library of sample MEM runs that
allow new users or overloaded mission planners to get a quick feel for the
characteristics of the meteoroid environment. This library provides both
visualizations of these runs and input files that allow users to replicate them
exactly. We also discuss the number of state vectors needed to obtain an
accurate representation of the environment encountered along our sample
trajectories, and outline a process for verifying that any given trajectory is
adequately sampled.
