Abstract

To support studies of Mercury’s internal structure, a MESSENGER mission goal is to measure the shape of Mercury. Radio-frequency occultation observations contribute to this objective. We describe here the techniques used to derive radius measurements from such observations. We report results from flyby and early-orbit observations and compare them with planet-shape measurements by the Mercury Laser Altimeter.
