ESA ministers commit to biggest ever budget

The significant boost in funding for ESA’s world-class and inspirational science programme will allow the first gravitational wave detector in space, LISA, to fly alongside the black hole mission Athena.

ESA’s Council at Ministerial Level, Space19+, has concluded in Seville, Spain, with the endorsement of the most ambitious plan to date for the future of ESA and the whole European space sector. Image: ESA

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.

The LISA Consortium

The LISA Consortium is committed to supporting the LISA mission. It includes all the main investigators involved in the highly successful LISA Pathfinder mission, a number of scientists who worked on the ground-based LIGO, Virgo, and GEO projects, and a number who worked on the Laser Ranging Interferometer on the GRACE Follow-On mission, thus making full use of the expertise accumulated so far. The LISA Consortium proposed and submitted the white paper The Gravitational Universe which was accepted for the ESA L3 slot.
