Earth-Moon Mass Ratio from Mariner 9 Radio Tracking Data

AbstractFollowing efforts to construct an accurate modelisation of Mars rotation starting from canonical equations in an Hamiltonian theoretical frame (Bouquillon and Souchay, 1996), we use recent results from radio tracking data of the Mars Pathfinder mission (Folkner et al., 1997) to modelize in the best way the motion of precession and nutation of the planet. A complete set of coefficients related to these two motions is presented, including the main effect due to the Sun and also those due to the two satellites Phobos and Deimos as well as to the planets. Morever, Oppolzer terms are calculated and included.

Mariner 9

AbstractA numerical theory of motion of the inner planets and Jupiter is presented. The numerical ephemerides were compared with the set of American and Russian radar observations of planets, obtained during 1961–1995 (nearly 60000 observations), together with range measurements of Martian landers Viking-1,-2 and Mariner-9 tracking data.The main fitted parameters were the elements of Mercury, Venus, Earth, Mars, the Astronomical Unit, the scale corrections to the reference surface of planets and variability of the gravitational constant. The parameters of Mars rotation, coordinates of Viking landers, elements and the mass of Jupiter, the masses of the three asteroids were evaluated from Viking landers observations.
