LISA Pathfinder tracera la voie vers la mission eLISA en testant, dans l’espace, le concept (les principes ?) de la détection d’ondes gravitationnelles.

L'endroit le plus silencieux du système solaire

LISA Pathfinder (LPF) placera deux masses d’épreuve en "chute libre" quasi parfaite, contrôlera et mesurera leur mouvement relatif avec une précision inégalée. Ceci sera effectué grâce à des thechnologies innovantes telles que des senseurs inertiels, un système de métrologie laser, un système à compensation de trainée et des micro-propulseurs délivrant des micro-Newton. L’ensemble de ces masses d’épreuve et leur environnement constitueront probablement un des endroits les plus "calmes" du système solaire.

Toutes ces technologies sont non seulement essentielles pour la mission eLISA, elles seront également à la base de toutes les missions qui voudront tester la théorie de la relativitié générale d’Einstein.

LPF sera lancé en novembre 2015.
