  We present preliminary results from a series of high-resolution N-body
simulations that focus on 8 dark matter halos each of order a million particles
within the virial radius. We follow the time evolution of hundreds of
individually tracked satellite galaxies and relate their physical properties to
the differing halo environmental conditions. Our main science driver is to
understand how satellite galaxies lose their mass and react to tidal stripping.
Unlike previous work our results are performed in a fully self-consistent
cosmological context. The preliminary results demonstrate that while
environment may vary considerably with respects to formation time and richness
of substructure, the satellites evolve similarly.
