The Rubble-Pile Asteroid Itokawa as Observed by Hayabusa
During the interval from September through early December 2005, the Hayabusa spacecraft was in close proximity to near-Earth asteroid 25143 Itokawa, and a variety of data were taken on its shape,Expand
A new class of radio pulsars
Sufficiently low magnetic field neutron stars which accrete for long times from a surrounding keplerian disk can be spun up to millisecond periods. After accretion ceases, such stars could becomeExpand
Mass and Local Topography Measurements of Itokawa by Hayabusa
Combined with surface observations, these data indicate that Itokawa is the first subkilometer-sized small asteroid showing a rubble-pile body rather than a solid monolithic asteroid. Expand
The Pluto system: Initial results from its exploration by New Horizons
The New Horizons encounter revealed that Pluto displays a surprisingly wide variety of geological landforms, including those resulting from glaciological and surface-atmosphere interactions as well as impact, tectonic, possible cryovolcanic, and mass-wasting processes. Expand
Regolith Migration and Sorting on Asteroid Itokawa
High-resolution images of the surface of asteroid Itokawa from the Hayabusa mission reveal it to be covered with unconsolidated millimeter-sized and larger gravels, indicating that it has experienced considerable vibrations, which have triggered global-scale granular processes in its dry, vacuum, microgravity environment.

Impact History of Eros: Craters and Boulders
Abstract Preliminary measurements of craters and boulders have been made in various locations on Eros from images acquired during the first nine months of NEAR Shoemaker's orbital mission, includingExpand
Magnetosphere Imaging Instrument (MIMI) on the Cassini Mission to Saturn/Titan
The magnetospheric imaging instrument (MIMI) is a neutral and charged particle detection system on the Cassini orbiter spacecraft designed to perform both global imaging and in-situ measurements toExpand
Eros: Shape, Topography, and Slope Processes
Stereogrammetric measurement of the shape of Eros using images obtained by NEAR's Multispectral Imager provides a survey of the major topographic features and slope processes on this asteroid. ThisExpand
Surface compositions across Pluto and Charon
The New Horizons team presents the complex surface features and geology of Pluto and its large moon Charon, including evidence of tectonics, glacial flow, and possible cryovolcanoes, as well as their analysis of the encounter data downloaded so far. Expand
The MESSENGER mission to Mercury: Scientific objectives and implementation
Abstract Mercury holds answers to several critical questions regarding the formation and evolution of the terrestrial planets. These questions include the origin of Mercury's anomalously high ratioExpand
