A global solution for the Mars static and seasonal gravity, Mars orientation, Phobos and Deimos masses, and Mars ephemeris
Abstract With the collection of six years of MGS tracking data and three years of Mars Odyssey tracking data, there has been a continual improvement in the JPL Mars gravity field determination. ThisExpand

Interior structure and seasonal mass redistribution of Mars from radio tracking of Mars Pathfinder.
Doppler and range measurements to the Mars Pathfinder lander made using its radio communications system have been combined with similar measurements from the Viking landers to estimate improvedExpand

Fluid Core Size of Mars from Detection of the Solar Tide
The solar tidal deformation of Mars, measured by itsk 2 potential Love number, has been obtained from an analysis of Mars Global Surveyor radio tracking. The observedk 2 of 0.153 ± 0.017 is largeExpand

Martian precession and rotation from Viking lander range data
The spatial orientation of the Martian pole of rotation and axial rotation parameters have been determined at a midpoint in the Viking epoch (January 1, 1980). The mean obliquity e and node ψ anglesExpand

DE 102: a numerically integrated ephemeris of the moon and planets spanning forty-four centuries.
It is pointed out that the 1960's were the turning point for the generation of lunar and planetary ephemerides. All previous measurements of the positions of solar system bodies were optical angularExpand

A determination of the masses of Ceres, Pallas, and Vesta from their perturbations upon the orbit of Mars
Estimates have been made for the masses of the asteroids Ceres, Pallas, and Vesta by measuring their perturbations upon the orbit of Mars. The complete set of planetary ephemeris observational data,Expand
