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
