With 2 years of tracking data collection from the MRO spacecraft, there is noticeable improvement in the high frequency portion of the spherical harmonic Mars gravity field. The new JPL Mars gravity fields, MRO110B and MRO110B2, show resolution near

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. This includes the measurement of the seasonal changes in the grav

Measurements of Mars' rotational variations can be conducted via Earth-based radio tracking observations of the Mars Pathfinder lander during an extended mission. Two-way range measurements between an Earth tracking station and the lander will enable

The k(sub 2) potential ove number which scales the tidal deformation of Venus by the Sun has been estimated from Doppler tracking of Magellan and Pioneer Venus Orbiter (PVO) spacecraft data. The nominal range for k(sub 2) from theoretical models is 0

A radially stratified and incompressible earth model with secular variation of the second degree gravity field J-dot(2) is used here to test sensitivity of data to viscosity increases with depth and convective boundary layer structure. Prior estimate

The strong planetary methane and hydrogen absorption at 2.0-2.4 microns are exploited in the present observations of the Saturnian coorbital satellites Janus and Epimetheus as they passed over the north pole of Saturn at superior conjunction. These o

The solar tidal deformation of Mars, measured by its k 2 potential Love number, has been obtained from an analysis of Mars Global Surveyor radio tracking. The observed k 2 of 0.153 ± 0.017 is large enough to rule out a solid iron core and so indicat

We model the present-day time-dependent gravity field of Antarctica driven by solid earth rebound response to deglaciation of a more extensive continental ice cover at Last Glacial Maximum (22–15 kyr BP). Among the various global components of late
