This paper addresses the question of revisit interval optimization for any Terrestrial Planet Finder architecture in cases where, during an observation, a planet is detected. The problem is introduced by discussing the case where the extra-solar system consists of a single extra-Earth, and then expanded to deal with the characterization of an extra-solar planetary system consisting of two, three, or more terrestrial planets. Solving orbits when multiple planets are observed is complicated by the need to properly identify each planet on successive observations, The ability to distinguish which planet is which can greatly affect the efficiency of orbit determination. For the present case, it is assumed that the planets are distinguishable, by some other means, for example, color. Optimal revisit intervals for these multiple-planet cases are compared with intervals previously derived for the single planet case. The results and their implications for system designs of direct terrestrial planet detections are discussed.
