LISA (Laser Interferometer Space Antenna) is the future large mission L3 at ESA (European Space Agency). It has been approved in 2017 after the success of the technological demonstrator LISA Pathfinder and the detection of gravitational waves (GW) by Ground-Based observatories LIGO -Virgo. The LISA Science Case is extremely rich both for Astrophysics, Cosmology and Fundamental Physics: observations of SuperMassive Black Hole Binaries until very high redshift, Extreme and Intermediate Mass Ratio Inspirals, Stellar Mass Black Hole Binaries, Galactic Binaries, Stochastic GW Background from early Universe and various foregrounds, etc. While there is no critical technology, LISA requires very high precision metrology and is a highly integrated instrument from hardware subsystems until on-ground processing. Actually, before having data stream usable for extracting GW sources, several processing steps have to be done both on-board and on-ground, to suppress part of the noises.

In this talk, after a quick presentation of the mission and an overview of the science case, I will present the LISA measurements and the various processing applied to the data. Finally, I will present the current status of the simulation, the Science Ground Segment including the Distributed Data Processing Center and the Data Analysis Pipeline developed within the LISA Data Challenge.
