The multi-object MOSAIC, to be installed at the Extremely Large Telescope (ELT) of ESO, is a complex instrument, consisting of optical (VIS) and near-infrared (NIR) spectrographs, operating at two resolutions of R~5,000 and 20,000, and can be used simultaneously in the NIR and optical. It will operate in six observing modes: VIS-MOS, NIR-MOS, mIFU-NIR, all at low and high resolutions. The MOSAIC design is based on a fully fibre-fed spectrograph concept, resulting in three basic modes of operation. These are defined so as to use as much of the ELT field-of-view as possible ($>$7 arcmin in diameter).
Phase A (Conceptual Design) was approved by ESO, and in 2023 it entered in Phase B, and more precisely presently in phase B1. The kick-off of this phase took place in 14-15/March/2023. It involves 24 institutional partners, 31 laboratories in 13 countries.
MOSAIC is optimized to provide high survey speed and high surface brightness sensitivity for faint sources. In this respect, it is a unique follow-up instrument for space missions and major ground based experiments, like JWST (2022), Euclid (2023), Rubin (2024), Roman (2027), or SKA (2027).
