Sutton, Ph.D., Chair _________________________________ Jeffrey C. Sanders, Ph.D. _________________________________ Lawrence B. A. Hatter, Ph.D. ii ACKNOWLEDGEMENT This thesis has been years in the making and is the product of input from many, many different people. I am grateful for the support and suggestions of my committee—Matt Sutton, Jeff Sanders, and Lawrence Hatter—all of whom have been far too patient, kind, and helpful. I am also thankful for input I received from Michael Gordin at Princeton and Helen Anne Curry at Cambridge, both of whom read early drafts and proposals and both of whose suggestions I have been careful to incorporate. Catherine Connors and Carol Thomas at the University of Washington provided much early guidance, especially in terms of how and why such a curious topic could have real significance. Of course, none of this would have happened without the support of Bruce Hevly, who has been extraordinarily generous with his time and whose wonderful seminars and lectures have continued to inspire me, nor without Graham Haslam, who is the best teacher and the kindest man I have ever known. -

Determination of Venus' Interior Structure with Envision
remote sensing Technical Note Determination of Venus’ Interior Structure with EnVision Pascal Rosenblatt 1,*, Caroline Dumoulin 1 , Jean-Charles Marty 2 and Antonio Genova 3 1 Laboratoire de Planétologie et Géodynamique, UMR-CNRS6112, Université de Nantes, 44300 Nantes, France; [email protected] 2 CNES, Space Geodesy Office, 31401 Toulouse, France; [email protected] 3 Department of Mechanical and Aerospace Engineering, Sapienza University of Rome, 00184 Rome, Italy; [email protected] * Correspondence: [email protected] Abstract: The Venusian geological features are poorly gravity-resolved, and the state of the core is not well constrained, preventing an understanding of Venus’ cooling history. The EnVision candidate mission to the ESA’s Cosmic Vision Programme consists of a low-altitude orbiter to investigate geological and atmospheric processes. The gravity experiment aboard this mission aims to determine Venus’ geophysical parameters to fully characterize its internal structure. By analyzing the radio- tracking data that will be acquired through daily operations over six Venusian days (four Earth’s years), we will derive a highly accurate gravity field (spatial resolution better than ~170 km), allowing detection of lateral variations of the lithosphere and crust properties beneath most of the geological ◦ features. The expected 0.3% error on the Love number k2, 0.1 error on the tidal phase lag and 1.4% error on the moment of inertia are fundamental to constrain the core size and state as well as the mantle viscosity.

NASA and Planetary Exploration
**EU5 Chap 2(263-300) 2/20/03 1:16 PM Page 263 Chapter Two NASA and Planetary Exploration by Amy Paige Snyder Prelude to NASA’s Planetary Exploration Program Four and a half billion years ago, a rotating cloud of gaseous and dusty material on the fringes of the Milky Way galaxy flattened into a disk, forming a star from the inner- most matter. Collisions among dust particles orbiting the newly-formed star, which humans call the Sun, formed kilometer-sized bodies called planetesimals which in turn aggregated to form the present-day planets.1 On the third planet from the Sun, several billions of years of evolution gave rise to a species of living beings equipped with the intel- lectual capacity to speculate about the nature of the heavens above them. Long before the era of interplanetary travel using robotic spacecraft, Greeks observing the night skies with their eyes alone noticed that five objects above failed to move with the other pinpoints of light, and thus named them planets, for “wan- derers.”2 For the next six thousand years, humans living in regions of the Mediterranean and Europe strove to make sense of the physical characteristics of the enigmatic planets.3 Building on the work of the Babylonians, Chaldeans, and Hellenistic Greeks who had developed mathematical methods to predict planetary motion, Claudius Ptolemy of Alexandria put forth a theory in the second century A.D. that the planets moved in small circles, or epicycles, around a larger circle centered on Earth.4 Only partially explaining the planets’ motions, this theory dominated until Nicolaus Copernicus of present-day Poland became dissatisfied with the inadequacies of epicycle theory in the mid-sixteenth century; a more logical explanation of the observed motions, he found, was to consider the Sun the pivot of planetary orbits.5 1.
