The primary goals of the Stellar Imager Vision Mission are to understand:
the dynamos that create the complex and variable magnetic fields in the sun and other stars.
the internal structure and dynamics of magnetically active stars, using spatially-resolved asteroseismology.
solar and stellar magnetic activity and their impact on space weather, planetary climates, and life.
Stellar imager is a cross-theme mission addressing science goals relevant both to the NASA Heliophysics and Astrophysics Divisions at
Goddard. It is a Flagship/Landmark Discovery Mission in the 2005 Heliophysics Roadmap. SI's goal is to revolutionize our understanding of:
solar and stellar magnetic activity and their impact on the climates and habitability of planets and life.
magnetic and accretion processes and their roles in the origin and evolution of structure and in the transport of matter throughout the
the close-in structure of active galactic nucleii (AGN) and their winds.
extrasolar planet transits and disks.
