17408 McAdams           Discovered 1987 Oct. 19 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
Jim V. McAdams (b. 1961) optimizes spacecraft trajectories at the Applied Physics Laboratory of Johns Hopkins University. He designed trajectories for the NEAR Shoemaker mission from the formative phase of NASA's Discovery Program in 1989 to landing on (433) Eros in 2001.
