Abstract	Ron Hess briefly discussed a pair of ongoing research projects. The first deals with the design of a nonlinear dynamic inversion controller for a small micro-air vehicle. This work is supported by a Post-baccalaureate grant from the Army Aeroflightdynamics Directorate at NASA Ames Research Center. The second research area deals with certification of rudder systems for transport aircraft. This latter project is driven to some extent by the loss of American Airlines Flight 587 in November, 2001. Sanjay Joshi discussed ongoing research in the area of planetary navigation architecture for cooperative autonomous ground-air space robots. The research is investigating means of allowing multiple robot teams to explore other planets, moons and asteroids. The particular architecture discussed involves an orbiting spacecraft, a lighter-than-atmosphere aerobot and a team of ground robots. The approach is intended to take advantage of the unique strengths of each team member, while minimizing the risk to individuals and the team as a whole.
