The Mars Science Laboratory mission aims to land a car-sized rover on Mars’ surface and operate it for at least one Mars year in order to assess whether its field area was ever capable of supporting microbial life. Here we describe the approach use

We present a volumetric iso-geometric finite element analysis based on Catmull-Clark solids. This concept allows one to use the same representation for the modeling, the physical simulation, and the visualization, which optimizes the design process a

We present an adaptive subdivision scheme for unstructured tetrahedral meshes inspired by the ! 3-subdivision scheme for triangular meshes. Existing tetrahedral subdivision schemes do not support adaptive refinement and have traditionally been driven

A NASA Mars technology program task is developing a prototype, embedded, real-time navigation system for Mars final approach and entry, descent, and landing using the Mars Network’s Electra ultrahigh frequency transceiver. The Mars Network is ideal
