The INTERHELIOPROBE project is being developed within the framework of the Federal Space Program of the Russian Federation. It is aimed at the research of the Sun from close distances including inner heliosphere and solution of the problems of solar corona heating, acceleration of the solar wind, origin of the solar flares and coronal mass ejections.


The ballistic scheme of the mission

The spacecraft (SC) will start from the Earth and due to the multiple gravitational maneuvers (GM) near the Venus will comes nearer to the Sun, saving due to it the fuel and reducing the time of the flight to the operational orbit. GMs near the Venus will allow also to incline the plane of the SC orbit with respect to the ecliptic plane and to carry out the observations of the near polar regions of the Sun. In perihelion on the distances about 40 solar radius the corotation will take place, i.e. within approximately 7 days SC will synchronously rotates with the Sun, hanging above the subsolar region. The corotation will allow carry out the special observations and in-situ measurements.
