Planetary Spacecraft Navigation

James Miller:

James Miller worked as the Assistant Navigation Team Chief on NASA's Viking Mission to Mars in 1976. In 2000, he received the Mechanics and Control of Flight medal from the American Institute of Aeronautics and Astronautics (AIAA) for his design of the navigation system used on the first spacecraft to orbit and land on the asteroid Eros. Furthermore, Miller designed a trajectory to leave Earth and orbit the Moon with no propulsive maneuvers whatsoever. This was the first practical solution of the four-body problem, and it has since been used on the space exploration missions Hiten, Genesis, and Grail.

Connie Weeks:

Connie Weeks' interest in control theory and estimation theory while working towards her undergraduate degree at Harvey Mudd College lead her to ultimately earn a PhD in mathematics from the University of Southern California. Her deep passion for undertaking complex tasks with the use of mathematical analysis lead her to understand the technicalities involved with orbit determination and spacecraft navigation. This was exactly the kind of problem solving required to adapt to her crucial roles with NASA JPL where she worked on shape estimation for two and three dimensional systems. Connie later went off to teach mathematics at Loyola Marymount University and published several research papers with the support of the NASA Jove research grant.
