I present new maps, photomosaics and geological interpretations of asteroid 951 Gaspra. Facets and limb concavities suggest a long history of large impacts producing 5 to 7 km diameter craters. Craters 1 to 4 km in diameter date the last facet-forming impact, though it is not clear which facet this formed. These craters are more numerous than previously thought because much of the area seen at high resolution seems to be depleted in these larger craters. Craters in that area probably date the… 
The astrophysical context of collision processes in meteorites
Chondrites are leftover solids from the early evolution of the solar protoplanetary disk that never experienced melting since their formation. They comprise unequilibrated assemblages of low‐ and
Space missions to small bodies: asteroids and cometary nuclei
The knowledge of the physical and dynamical properties, distribution, formation, and evolution of small bodies is fundamental to understand how planet formation occurred and, even more importantly,
Asteroids Close-Up: What We Have Learned from Twenty Years of Space Exploration
Asteroids are objects of fundamental scientific importance for several reasons. They are the remnant debris from the formation of the inner solar system. They offer therefore the unique opportunity
Mapping Irregular Bodies
Map projecting small, irregular bodies present in the Solar System is not a trivial task. The first 3D models attempting to reconstruct the Martian satellite Phobos occurred at the end of the 1980s.
Planetary remote sensing with physical scattering models
Understanding the light scattering properties of Solar System bodies is important, especially in the case of the small bodies. For these objects, most of our data is photometric, i.e. measurements of
Analysis of the potential field and equilibrium points of irregular-shaped minor celestial bodies
The equilibrium points of the gravitational potential field of minor celestial bodies, including asteroids, comets, and irregular satellites of planets, are studied. In order to understand better the
Human and Robotic Mission to Small Bodies: Mapping, Planning and Exploration
This study investigates the requirements, performs a gap analysis and makes a set of recommendations for mapping products and exploration tools required to support operations and scientific discovery


Galileo Encounter with 951 Gaspra: First Pictures of an Asteroid
Galileo images of Gaspra reveal it to be an irregularly shaped object that appears to have been created by a catastrophic collisional disruption of a precursor parent body.
Discovery of Grooves on Gaspra
Abstract We report the discovery of grooves in Galileo high-resolution images of Gaspra. These features, previously seen only on Mars' satellite Phobos, are most likely related to severe impacts.
The Geology of Gaspra
The surface of Gaspra can be divided into several facets separated by ridges. Superimposed on the facets and ridges are two populations of craters. Type 1 craters are crisply defined and constitute a
Cratering on Gaspra
Abstract Galileo flyby images of 951 Gaspra show a crater population dominated by fresh craters several hundred meters in diameter and smaller. They must represent a production population because
Collisional History of Gaspra
Abstract Interpretation of the impact record on Asteroid 951 Gaspra requires understanding of the effects of collisions on a target body of Gaspra's size and shape. Recent hydrocode models show that
Galileo's Encounter with 951 Gaspra: Overview
Abstract On 29 October 1991, the Galileo spacecraft carried out the first ever encounter of a minor planet, flying by Asteroid 951 Gaspra at a distance of 1600 km. We summarize findings derived from
Ejecta Blocks on 243 Ida and on Other Asteroids
Abstract Seventeen positive relief features ∼45–150 m across are identified as probable blocks in Galileo high-resolution images of Ida. Their presence provides direct evidence for regolith retention
Galileo Photometry of Asteroid 951 Gaspra
Galileo images of Gaspra make it possible for the first time to determine a main-belt asteroid's photometric properties accurately by providing surface-resolved coverage over a wide range of
The topography of Janus
A topographic model of Saturn's larger co-orbital satellite Janus was derived from the shapes of limbs and terminators in Voyager images, modified locally to accommodate large craters and ridges. The
The Shape of Gaspra
Abstract Images of Gaspra obtained during the October 1991 Galileo flyby have been used to derive a shape model of the asteroid. Gaspra is a highly irregular object with principal diameters of 18.2,
