Mass wasting and the Coriolis effect on asteroid Vesta
… to the Rheasilvia impact basin on asteroid (4) Vesta's southern hemisphere. The giant basin is 500km in diameter, with a centre which nearly coincides with the rotation axis of Vesta. The Rheasilvia basin partially overlaps an earlier, similarly large impact basin, Veneneia. Mass motion within …

Global Surface Modification of Asteroid 4 Vesta Following the Rheasilvia Impact
4 Vesta, the second most massive asteroid in the Solar System, was the recent target of NASA’s Dawn mission, which spent many months orbiting and analyzing the body. A geologically young (~1 Ga) giant impact basin, Rheasilvia, which has a diameter nearly equal to that of Vesta, dominates Vesta’s …

Geophysical investigation of Vesta, Ceres and the Moon using gravity and topography data
… we study three Solar System bodies: asteroid Vesta, dwarf planet Ceres and the Earth's Moon. Using the data from the Dawn spacecraft, we find that once hot and hydrostatic, Vesta is no longer either. It was despun by two giant collisions. We use the Dawn gravity/topography data along with …

Positioning in geophysics : applications to GPS seismology, airborne gravimetry, and the Dawn Spacecraft at Vesta
… 5 focus on the Dawn mission to the asteroid 4 Vesta. Chapter 4 details the use of spacecraft image constraints in the orbit determination software GEODYN, which is used by NASA/GSFC for trajectory reconstruction and geophysical analyses of planets. Image constraints are shown to converge an …

Water and volatile element accretion to the inner planets
… and F content of the eucrite parent body, 4 Vesta. In chapter 6, I determine the source of water for 4 Vesta and determine that carbonaceous chondrites delivered water to this body. Chapter 7 discusses degassing on 4 Vesta while it was forming.

Forging asteroid-meteorite relationships through reflectance spectroscopy
… belt. A number of small objects near asteroid 4 Vesta were found to have near-infrared spectra similar to the eucrite and howardite meteorites, which are believed to be derived from Vesta. These asteroids appear almost certainly to be fragments of Vesta. Spectral variations between these objects …

Magnetic fields in the early solar system
… believed to originate from the asteroid Vesta, suggest that Vesta once hosted a magnetic core dynamo. New techniques developed during the course of these measurements permit ongoing and future investigations of the remanent magnetizations of new meteorites and terrestrial rocks. In …

The History of Water and Other Associated Volatiles in Howardite-Eucrite-Diogenite Meteorites
… a differentiated basaltic asteroid (4 Vesta) and are some of the oldest igneous rocks in the Solar System. Understanding their volatile histories, therefore, can help us to constrain some of the processes that operated on Vesta early in Solar System history. <br></br><br></br> Using the …

Experimental studies of magmatic differentiation and the effects of water on phase stability
… 1 models the crystallization of the asteroid Vesta, which melted almost completely during the early history of the solar system. Chemical modeling of the crystallization of this water-free "magma ocean" shows that the howardite-eucrite- diogenite (HED) meteorite suite that makes up Vesta's …

Previous studies of the Ar-Ar and K-Ar isotope systems applied to impact melt glass, rocks, and mineral fractions, have yielded ages that are interpreted to indicate that …
