According to TASS, the Space Research Institute of the Russian Academy of Sciences (IKI RAS) 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 the solution of 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 an orbiter and a lander. The first is to investigate the dynamics, the nature of the superrotation of the atmosphere of Venus, 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 landing module, it will have to investigate the composition of the soil at a depth of several centimeters, the processes of interaction of the surface substance 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, in particular, two small satellites, which were proposed to be launched to the Lagrange points L1 and L2 of the Venus-Sun system, was studied. However, now it became known that it was decided to abandon these sub-satellites.
βThe sub-satellites were part of the expanded Venera-D program. Initially, we planned to launch two or more such devices to two similar points in the orbit of Venus, which were supposed to study the nature of the interactions of the solar wind, the ionosphere and magnetosphere of Venus, βsaid the IKI RAS.
The launch of vehicles under the Venera-D project is now planned no earlier than 2029.
