Abstract
In this paper we present a review of the past, current and future space
missions relevant for observing stellar activity from space. In the past,
missions were focused on UV and X-ray fluxes, variability and spectroscopy.
Currently coronal
spectroscopy diagnostics are developed. HST high resolution imaging in the
visible and near IR give access to circumstellar disks and outflows.
The future space missions will
concentrate on space photometry (for asteroseismology, exoplanets search and
microvariability due to activity) and interferometry (for measuring stellar
sizes and environments).
