Russian engineers have suspended work on the mission to the sun "Interheliozond"

So far, the launch date of Interheliozond is planned for 2026 from the Baikonur Cosmodrome on a launch vehicle

Soyuz-2 with the Fregat upper stage, but it may be changed in the future.

It was planned that the research stationInterheliosond will consist of an orbital transfer module, a heat shield to protect the complex of scientific equipment and service systems from heating by solar radiation, and a propulsion system that provides the necessary corrections during the flight to the Sun.

Interheliozond was supposed to study solar active phenomena, the solar corona, the wind, and the polar regions of this star. The distance of study is up to 70 Sun radii.

There were issues related to some excess mass: it was necessary to put into orbit with certain characteristics, with the expectation of a specific rocket, which required restrictions on the mass. These questions were not finally linked, so it was necessary to refine the conceptual design in terms of clarifying these characteristics. At this point we have stopped.

Participate in the creation of a scientific missionseveral organizations, including the S. Lavochkin Scientific and Production Association, the Institute of Space Research of the Russian Academy of Sciences (the principal executor for scientific equipment), the IZMIRAN, the P. Lebedev Physical Institute and others.

Previously, Hi-Tech spoke in detail aboutParker Solar Probe, the only successful mission to the Sun to date, and its operating methods. Recently, the Parker Probe began its second orbit around the Sun, as a result of which it will again approach the star at a distance of 24 million km.
