Lunar geophysics, geodesy, and dynamics
Experience with the dynamics and data analyses for earth and moon reveals both similarities and differences. Analysis of Lunar Laser Ranging (LLR) data provides information on the lunar orbit,
Planetary seismology and interiors
The placing of the first seismometer on the Moon by the Apollo 11 astronauts in 1969 started the field of planetary seismology. In the following years five other seismic stations were established on
The future of planetary geophysics
Meeting report Nick Teanby and Neil Bowles look to the future for planetary geophysics, drawing together ideas discussed at an RAS Discussion Meeting in November.
Planetary core size: A seismological approach
A key parameter for understanding the geodynamics of a terrestrial planet is the size of its core. Numerical evaluation of 28 different interior structure models of Mercury, Venus, Earth, the Moon,
Scientific rationale and requirements for a global seismic network on Mars. Report of a workshop.
Little is known of the internal structure or composition of Mars or the present rates and characteristics of tectonic activity and meteoroid impacts. The scientific tool best suited to address these
Seismic tomography of the Moon
We attempted to determine the first three-dimensional P and S wave velocity and Poisson’s ratio structures of the lunar crust and mantle down to 1000 km depth under the near-side of the Moon by
The Selenographical distribution of deep moonquake epicenters
The observed selenographical distribution of the epicenters of the deep moonquakes is explained using a simple lunar model with a low Q deep interior and assuming that the number of epicenters per
LunarEX—a proposal to cosmic vision
While the surface missions to the Moon of the 1970s achieved a great deal, scientifically much was also left unresolved. The recent plethora of lunar missions (flown or proposed) reflects a

A new seismic model of the Moon: implications for structure, thermal evolution and formation of the Moon
Abstract The seismic determinations of the crustal thickness and mantle velocities are key parameters for most geophysical and geochemical lunar studies. We determine a new seismic model of the Moon

Pre-capture orbits of the moon
If the mass of the Earth was not considerably larger than at present, the pre-capture orbit of the Moon was in the range 0.9–1.1 A.U. Capture occurred within several 108 years after formation of the
The Origin of the Moon
Explanation of the Moon's composition in a model for the condensation of the planets from a cloud of solar composition suggests that the Moon accreted at higher temperatures and lower pressures than
New Seismic Data on the State of the Deep Lunar Interior
Direct shear-wave arrivals from seismtic events originating on the far side of the moon are not observed at some of the stations of the Apollo seismic network. These data suggest that the material in
The deep seismic structure of the moon
Data from 24 deep moonquakes are used to investigate the seismic structure of the lunar interior below the 300-500 km level. The deep moonquakes provide an uninterrupted ray-path coverage of the
Meteoroid Storms Detected on the Moon
Seismometers on the moon have detected several brief periods of enhanc ed meteoroid-impact activity, believed to represent encounters of the moon with "c louds" of objec ts in the kilogram range. The

The use of polarization filters is demonstrated on lunar seismograms. Body-wave arrivals from artificial impacts are identified as surface reflections, which may be used for improving our knowledge
Geophysical Data and the Interior of the Moon
Geophysical data and physical properties of the lunar interior are considered, giving attention to density, gravity field, viscosity, the strength of lunar materials, electrical conductivity, and
Natural lunar seismic events and the structure of the moon
The gross structure of the moon may be determined from natural seismic events, supplemented by artificial impacts at close ranges. The moon has a rigid mantle below a layered crust. At a depth of
The 25-km Discontinuity: Implications for Lunar History
The lunar velocity profile and laboratory data on terrestrial and lunar rocks are constraints on models of lunar history. They show that shock-induced microcracks are absent from the rocks present in
