A growing interest of the space scientific community for trajectories towards, around and from Lagrangian points has been registered in recent years. In particular, the three-body problem is one of the most studied models not only in celestial mechanics, but also in mathematics. For the early first solar system exploration missions (like Voyager), a patched conics model was satisfactory to compute the trajectory. As interplanetary missions became more demanding (as ...

With the emergence of new businesses in the space market, historic launch service providers and newcomers are proposing cheaper launch services through low-cost launchers or reusable ones. In order to introduce these new actors of the launcher sector,  the COMET-ORB is organizing a seminar on Low-Cost Launcher Services and their Impact. This seminar is an opportunity to discover some of the new launchers that will soon come to fly, their ...

This main purpose of this seminar was to make experts in space guidance and electric propulsion exchange on diverse propulsion technologies and on the compliance of these technologies with future missions. But it was also a time to discuss the effects of these technologies on guidance methods. As electric propulsion reaches maturity, it allows studies about new missions in which guidance algorithms have been adapted or renewed. The aim of the seminar ...

This seminar focused on the optimal control methods used on a daily basis in three domains : finance, structures and medical Imaging Context Optimal control is a building block of mission analysis via trajectory optimisation : launcher, transfer or rendezvous ; low or high thrust ; two, three or four body problem ; local or global solution, etc… Research is very active with preferred classes of methods depending on the applications and the epochs. However optimal control is not ...

Cet atelier créativité était dédié à l'idéation de sujets de R&T inclus dans le périmètre de la COMET ORB en amont de l'appel à idées de R&T du CNES. Il a réuni une vingtaine de participants permettant de faire émerger un réservoir d'idées en cours d'exploitation. Pour plus d'informations n'hésitez pas à contacter les animateurs de la COMET ORB.
