The Space Research Institute of the Russian Academy of Sciences (IKI RAS), according to TASS, has clarified plans for the implementation of the Venera-D mission, aimed at exploring the second planet of the solar system.
The named project involves solving a wide range of scientific problems. This is a comprehensive study of the atmosphere, surface, internal structure and surrounding plasma of Venus.
The basic architecture provides for the creation of orbiters and lander. The first is to investigate the dynamics, the nature of the superrotation of the Venusian atmosphere, the vertical structure and composition of clouds, the distribution and nature of an unknown absorber of ultraviolet radiation, the emissivity of the surface on the night side, etc.
As for the lander, it will have to investigate the composition of the soil at a depth of several centimeters, the processes of interaction of surface matter with the atmosphere and the atmosphere itself, as well as seismic activity.
For a more complete solution of scientific problems, the possibility of including auxiliary vehicles in the mission was studied, in particular, two small satellites, which were proposed to be brought to the L1 and L2 Lagrange points of the Venus-Sun system. However, it has now become known that it has been decided to abandon these subsatellites.
“The sub-satellites were part of the extended Venera-D program. Initially, we planned to launch two or more similar devices to two similar points in the orbit of Venus, which were to study the nature of the interactions between the solar wind, ionosphere and Venus magnetosphere.“, – told in IKI RAN.
The launch of the devices within the framework of the Venera-D project is now planned not earlier than 2029.
