Two different types of Radio Science (RS) experiments were conducted with Clementine: radio tracking experiments in which the magnitude and direction of the planet's gravity field were derived from the Doppler and ranging measurements, and radio propagation experiments in which modulation on the signal received on Earth could be attributed to properties of the intervening medium. Two types of radio propagation experiments were carried out: radio occultations by the lunar limb and bistatic radar scattering from the lunar surface.

The Clementine spacecraft telecommunications subsystem served as part of a Radio Science instrument for investigations of the Moon. The remainder of the 'instrument' was located at ground stations of the NASA Deep Space Network (DSN). Much of the equipment at both ends was shared, being used for routine telecommunications as well as for Radio Science.

ODE supports the search, retrieval, and download of data from the bistatic surface scattering measurements (raw, partially processed FND, and reduced data) and gravity measurements. Information about RS experiment products can be found in:
