The Origins Space Telescope is one of the four flagship missions currently under study for the 2020 US decadal survey. OST will cover the full infrared wavelength domain, from 6.5 to about 500 microns. The science goals and associated measurement requirements for OST are being established by a
community-based Science and Technology Definition Team (STDT). The STDT is supported by a NASA
Center Study Office based at NASA’s Goddard Space Flight Center, with partners at several other
NASA Centers and industry teams.
I will present the first mission concept, a cooled 9m telescope equipped with five instruments enabling sensitive imaging, spectroscopy and polarimetry to answer compelling questions in astrophysics such as the origin of black holes and galaxies, the origins of elements, the trail of water from the cold ISM to
disks and planets, etc.
This talk will present the OST study and describe the french participation supported by CNES.
