Thales Alenia Space wins ESA study contract for LISA mission to investigate the history of Universe
Cannes, June 4th 2018 - Thales Alenia Space, the joint venture between Thales (67%) and Leonardo (33%), announced today that it has won a contract from the European Space Agency (ESA) for the Phase A study of LISA (Laser Interferometer Space Antenna), the third large-class mission in ESAs Cosmic Vision 2015-25 Program.
LISA will be the first space-based gravitational wave observatory. Its major aim is the detection of gravitational waves, ripples in the fabric of space-time created by large and dense celestial bodies with very strong gravity - such as black holes - that move with accelerated motion, as predicted by Albert Einsteins theory of general relativity. The mission will give scientists a completely new view of the cosmos compared with traditional observation techniques, and will hopefully help unveil some of its many mysteries.
LISA will consist of three spacecraft in a triangular formation, separated by 2.5 million kilometers, following the Earth in its orbit around the Sun. Each satellite will carry two reference masses. Laser beams will be transmitted between satellites to measure the displacement of these masses with a resolution ten times smaller than an atom. Thales Alenia Space will lead the feasibility study phase ending in January 2020. This contract marks a major step forward for the LISA mission and also confirms Thales Alenia Space's traditional key role in many of Europe's leading scientific missions.
Technical details
Phase A includes the identification of a feasible mission design, the definition of a baseline for the spacecraft and its subsystems, including payload interfaces, the evaluation of achievable science based on extensive analyses, and the definition of a development road map.
LISA (Laser Interferometer Space Antenna) will use the same technique as two other programs, LIGO (Laser Interferometer Gravitational-Wave Observatory) and Virgo (European Gravitational Observatory), to detect gravitational waves, namely measuring the displacement of reference masses using laser interferometry. But it will extend the observation envelope in the lower frequency spectrum, inaccessible from the ground, and considerably enhance capabilities and verification.
