Autonomous vision-based navigation and shape reconstruction of an unknown asteroid during approach phase
Autor: Panicucci, Paolo
Le but de cette thèse est de présenter des algorithmes basés vision pour permettre la navigation autonome de la sonde et la caractérisation d'un astéroïde inconnu avec une camera monoculaire pendant la phase d'approche.L'état de l'art de la na

Nadir remote sensing of the night side of Mars is challenging, mainly due to the low signal-to-noise ratio of such observations. We show in a companion paper that the abundance of carbon monoxide (CO) during night can be retrieved from the observatio

Origine des éléments volatils et chronologie de leur accrétion au sein du Système Solaire interne : Apport de l'analyse in-situ des achondrites
Autor: Deligny, Cécile
Volatile elements such as hydrogen and nitrogen control the evolution of planetary bodies and their atmospheres, and are essential elements for the development of life on Earth. Nevertheless, the origin of volatile elements and the timing of their ac

Gravitation tests on the solar system scale
Autor: Bernus, Léo
Publikováno v: Astrophysique [astro-ph]. Université Paris sciences et lettres, 2020. Français. ⟨NNT : 2020UPSLO004⟩
We constrain alternative theories to general relativity using the planetary ephemeris INPOP.First, we give the conditions for achieving such constraints. We show that it is crucial to fit all the parameters of INPOP atthe same tame as we constrain th

The rejection of the geocentric model, that was a crucial legacy from ancient astronomy, became the major paradigm shift brought by Copernicus’ discovery. But from a strictly scientific point of view, and as decisive as was the Copernican revolutio

La navigation astronomique d'une sonde autonome, pour l'exploration du système solaire à l'ère de Gaia
Autor: Duchemin, Yann
Publikováno v: Astrophysique [astro-ph]. Université Paris sciences et lettres, 2019. Français. ⟨NNT : 2019PSLEO002⟩
Spacecrafts are nowadays mainly guided by Deep Space Network (DSN) radio telescopes. Stellar sensors can only provide the attitude (orientation) of the probe. The increasing number of spacecrafts, the use of ion thrusters involving the abandonment of
