The Planetary Science JournalThe surface of Mercury is highly space weathered, and the products of space weathering are different than on the Moon. Here we simulate the interaction of solar wind ions with the surface of Mercury by implanting low-iron-bearing (∼3 wt% Fe) olivine ...

The correlation of VLF propagation variations with atmospheric planetary-scale waves [PDF]
Variations in the received daytime phase of long distance, cesium-controlled, VLF transmission were compared to the height variations of the 10-mb isobaric surface during the first three months of 1965 and 1969.

Planetary rover technology development requirements [PDF]
Planetary surface (including lunar) mobility and sampling capability is required to support proposed future National Aeronautics and Space Administration (NASA) solar system exploration missions. The NASA Office of Aeronautics and Space Technology (OAST)

Rapid Impact Crater Relaxation Caused by an Insulating Methane Clathrate Crust on Titan
The Planetary Science JournalTitan’s impact craters are hundreds of meters shallower than expected, compared to similar-sized craters on Ganymede. Only 90 crater candidates have been identified, the majority of which have low certainty of an impact origin.

Natural fracture systems on planetary surfaces: Genetic classification and pattern randomness [PDF]
One method for classifying natural fracture systems is by fracture genesis. This approach involves the physics of the formation process, and it has been used most frequently in attempts to predict subsurface fractures and petroleum reservoir productivity.

Mercury Spectrophotometric Modeling Using MESSENGER Data
The Planetary Science JournalMercury is covered by a regolith that affects how light is scattered from the planet’s surface. To deduce the physical properties of Mercury’s regolith, we use spectrophotometry from the Mercury Dual Imaging System instrument of NASA’s MErcury Surface ...
