INTERHELIOPROBE

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.

Basic scientific problems

Determine the mechanisms of the solar corona heating and acceleration of the solar wind
Investigate thin structure and dynamics of the solar atmosphere
Define the nature and global dynamics of the solar flares and coronal mass ejections and their influence on the heliosphere and space weather
Explore the Sun as the powerful and changeable accelerator of the particles
Observe from high heliolatitude and to investigate the solar atmosphere and the corona in polar and equatorial regions

Observations and in-situ measurements

The feature of the SC orbit will allow carry out the series of original observations and in-situ measurements important for the solution of the scientific problems:
Observations of the solar atmosphere with the high spatial resolution
Corotational observations and measurements
In-situ measurements near the Sun
Out-of ecliptic observations and measurements
Stereo observations of the Sun (in combination with others SC)
Observations of the far side of the Sun invisible from the Earth
