Conference proceedings 1975where it might be thought that very few problems were left un solved in celestial mechanics, we discover that new and more challenging questions must be answered. The pre cision of observations reaches the centimeter level and physical phenomena which had been disregarded come into play. We need a

Orbit Determination in the Presence of Atmospheric Drag Errorssequential fashion. In addition to estimates of the state, sequential estimates of the unmodeled aerodynamic accelerations are determined also. The estimates of the unmodeled accelerations can be used to improve knowledge of both the vehicle drag parameter and the atmospheric density.

Solar Radiation Pressure and Balloon Type Artificial Satellitesl with those obtained from some direct numerical integrations. It is shown that this model can be suitably combined with the Brouwer-Hori model in order to study the long term perturbations on the trajectories of balloon satellites arising from the joint action of solar radiation pressure and atmospheric drag.

Optimal Impulsive Interplanetary Transferssfers. This realizable solution includes the effects of the inclination and eccentricity of the orbits of the planets. It applies directly for cases in which a two-impulse transfer is the optimal solution; the results are presented as functions of the corresponding idealized Hohmann transfers.
