The DynaMICS1 space perspective is devoted to the long trend (decades or centuries) global properties of the Sun. Its main scientific objectives are: (1) to build a complete 3D rotating and magnetic picture of the Sun from the central core up to the chromosphere thanks to new observational constraints, (2) to deduce the different sources of dynamo and their interplay, (3) to build models of the already observed great maxima and minima solar activities and give some predictions for the coming decades, (4) to produce outputs useful to quantify the solar variabilities which impact on the Earth climate, (5) to extend the dynamical properties for solar-like stars and build dynamical stellar evolution codes. Understanding the magnetic field of the radiative zone is a crucial objective as it plays a key role in the long-term Sun-Earth relationship. We outline here the instruments: GOLFNG, MOF, SODISM, PREMOS, SOVAP that we are developing to reach this goal. They will detect, from space, solar acoustic and gravity modes together with radius and irradiance variations from UV to visible. Part of them will also improve our knowledge on the transition region between photosphere and chromosphere. These instruments must observe the Sun during a decade from an orbit which ensures continuity, stability and measurements of tiny variations.
