Radio Science as tool for testing alternative theories of gravity: the BepiColombo mission case |
|
Abstract |
Radio Science (RS) deals with radio tracking of interplanetary probes, looking for changes in the frequency as well as roundtrip light time of signals to investigate geophysical phenomena and for tests of fundamental physics. For this reason, RS systems are now a custom in space missions. BepiColombo is a ESA/JAXA mission to Mercury mounting a Ka-band transponder in order to perform a very accurate RS experiment. In particular, it will be possible to test General Relativity (GR) and alternative theories with an unprecedented level of accuracy. The Celestial Mechanics Group of the University of Pisa developed a new dedicated software, ORBIT14, to simulate the RS experiment of BepiColombo and to analyze the future real data (as it is already doing for the Juno mission data). In this talk, after a brief description of the dedicated software, we will report on the relativity results of a full set of simulations, carried out in the most up-to-date mission scenario. |
