Abstract:

Abstract The next phase in the robotic exploration of the Saturnian system will target unresolved questions about the gas giant’s atmosphere, interior, magnetosphere, and rings that were left open by investigations on board the Cassini mission. Among these, we find gravity science objectives, which relate mainly to explaining the origin of the large wind-induced gravity signal and reconciling existing incongruities regarding the internal density distribution. Here we attempt to identify which future observations may yield additional information about Saturn’s internal mechanisms. We report on

Abstract Gravity as both fact and theory is one of the great success stories of recent research on international trade, and has featured prominently in the policy debate over Brexit. We first review the facts, noting the overwhelming evidence that trade tends to fall with distance. We then introduce some expository tools for understanding constant-elasticity-of-substitution theories of gravity as a simple general-equilibrium system. Next, we point out some anomalies with the theory: mounting evidence against constant trade elasticities, and implausible predictions for bilateral trade balances.

Abstract:

Abstract The Gravity Imaging Radio Observer (GIRO) is a concept for a high-performance, battery-powered radio probe designed to be released in the proximity of a target planetary body to study its gravitational variations. Using the host spacecraft’s communications system, the GIRO probes would receive and transmit a coherent carrier signal back to a host spacecraft, providing high-precision range-rate data with accuracy ≤1 μm s−1 at a 60 s count time, which is 10–100 times better than the performance of conventional ground-based radiometric data. GIRO is spin stabilized, which significantly r

Originating from Newton’s gravitational theory which was posed in 1687; the concept of gravity equation was primarily used by Tinbergen in the field of international trade analysis in 1962. After Tinbergen, Pöyhönen, Linnemann, Anderson, Santos and Tenreyro, Bergstrand and Egger, Deardorff and also Wooldridge developed the theory of gravity. And gravity model has become progressively well-liked in the academic publications. The aim of this study is to determine the literature belonging to the years between 1980 which is the starting point for “gravity” related studies’ being published on Web o

Abstract:

Context. Chinese lunar missions have grown in number over the last ten years, with an increasing focus on radio science investigations. In previous work, we estimated two lunar gravity field models, CEGM01 and CEGM02. The recently lunar mission, Chang’e 5T1, which had an orbital inclination between 18 and 68 degrees, and collected orbital tracking data continually for two years, made an improved gravity field model possible. Aims. Our aim was to estimate a new lunar gravity field model up to degree and order 100, CEGM03, and a new tidal Love number based on the Chang’e 5T1 tracking data combin

Abstract A network of 30 gravity base stations have been established. The dynamic drift curves show an average drift rate of less than 0.006 mgal/min. The observed gravity values have repeatability of 0.08 mgal, and can be used for regional gravity surveys.

Abstract:

Abstract A key objective for the future exploration of the icy moon Enceladus is the characterization of the habitable conditions in its internal ocean. Radio science instrumentation on board a spacecraft in a low-altitude orbit about Enceladus would enable gravity measurements that are fundamental to providing constraints on its internal structure. We present here the concept of operations and expected results of the gravity investigation for a New Frontiers–class mission. Numerical simulations are carried out to determine the gravity field in spherical harmonics to degree and order 30 and th
