Inner heliosphere
Intergeliozond
Intergeliozond is a Russian heliophysics observatory concept aimed at close-in solar and inner-heliosphere measurements from off-ecliptic viewpoints.

The mission remains a concept study; official materials describe the science goals, but a launch date, launcher, and operations timeline are still TBD.
Official mission site ↗The mission
Intergeliozond is an IKI-led heliophysics concept that would study the Sun and the inner heliosphere from close distances and from positions outside the ecliptic plane, giving Russian researchers a new solar vantage point.
