Abstract The solar and heliospheric observatory, Soho, will be placed into a halo orbit around the L1 Sun-Earth Lagrangian point in 1995. It will carry a set of instruments to study the physical phenomena in the solar atmosphere that heat the solar corona, the mechanisms by which the solar corona expands into the solar wind, and investigate the structure of the solar interior by the study of solar oscillations, both in velocity and in intensity (Helioseismology). In this paper we describe the mission and the investigations to be carried out with the helioseismology instruments in the payload. A solar oscillations imager will measure velocity oscillations of degree up to 4000, while two other instruments will measure very long series of low degree modes of oscillation, one of them in velocity and the other in irradiance. The data obtained will be used to study the radial stratification and the longitudinal variation of the physical characteristics of the Sun, as well as many dynamical phenomena of the upper layers of the solar atmosphere.
