DESCRIPTION:MOSAIC is the future multi-object fibre spectrograph for the E
 SO 39m Extremely Large Telescope (ELT). It is a first generation instrumen
 t\, with unique capabilities in terms of multiplex\, wavelength coverage a
 nd spectral resolution. While ELT first light instruments will focus on ex
 ploiting the central part of the ELT focal plane\, MOSAIC is designed to c
 over the largest possible area (~40 arcmin²) thanks to an original steppe
 d and tiled focal plane design which allows parallel observations in diffe
 rent modes. MOSAIC is a versatile multi-object spectrograph working in in 
 both the Visible and NIR domains\, offering both high multiplex and multi-
 IFU capabilities\, optimized to achieve the best possible signal-to-noise 
 ratio on the faintest sources\, from our Galaxy to the epoch of the reioni
 zation. In this respect\, it will be a privileged survey machine for the f
 ollowup of sources being discovered by current and future major facilities
 \, such as JWST\, Euclid\, ROMAN or SKA. I will review the main expected s
 cientific contributions of MOSAIC\, focusing on the study of the first gal
 axies formed in the Universe.
