  The Sino-French space mission SVOM (Space-based multi-band astronomical
Variable Objects Monitor) is mainly designed to detect and localize Gamma-Ray
Burst events (GRBs). The satellite, to be launched late 2021, embarks a set of
gamma-ray, X-ray and optical imagers. Thanks to its pointing strategy, quick
slew capability and fast data connection to earth, ground based observations
with large telescopes will allow us to measure redshifts for an unprecedented
sample of GRBs. We discuss here the overall science goals of the SVOM mission
in the framework of the multi-wavelength and multi-messenger panorama of the
next decade. Finally we show how some developments of the SVOM mission will be
helpful for the THESEUS project.
