DescriptionTrajectoire-sondes-Grail-fr.png	Français : Trajectoire des sondes spatiales lunaires GRAIL lancées en septembre 2011 et chargées de cartographier le champ de gravité lunaire. Les sondes rallient l'orbite lunaire après un transit de 3 mois passant par le point de Lagrange L1 afin de pouvoir dégazer et économiser du carburant. Version en français. English: The figure shows GRAIL-A and GRAIL-B trajectories for a launch at the open and close of the launch period. The low-energy trajectories leave Earth following a path towards the sun, passing near the interior Sun-Earth Lagrange Point 1 (Earth Libration Point 1) before heading back towards the Earth-moon system. French version.
