the NASA is Roscosmos completed the project of their joint Venera D mission, whose goal is to study the atmosphere and the surface of this inhospitable planet with 100 atmospheres of pressure and 500 degrees.
The mission consists of two basic elements: the orbiter and the landing craft that will be built in Russia. A small station of the NASA long-term in the lander – which, as expected, will work on the surface of Venus for 2 or 3 hours–, which will continue to work for 60 Earth days after the lander stops working. The infernal conditions in the atmosphere and in the surface of Venus prevent microelectronics from resisting longer.
the lander The Russian takes photos with panoramic cameras, stereo and high-resolution cameras. The resulting images will answer many questions, he told sputniknews.com Liudmila Zasova, co-director of the Russian part of the Scientific working group Set up on the Venera D. project
The launch windows are discussed for 2026, the end of 2027, 2029 and 2031. Even if the funding starts this year, by the first date it will not be reached in time, and rather it will be 2027, he said .
The working group, after studying the scientific tasks of Venera D, discovered a type of "voids" in the scientific program. So, in addition to the small long-term station, which is included as a device in the lander, the NASA proposed additional elements that can also be included in the mission.
These are two more complex stations that can live 120 days in Venus. His goal is to study atmosphere and the first study on the seismic activity of the planet. Now all models of the internal structure of Venus, which have no other experimental data, are based on the study of seismic phenomena in land. The proposed stations, if they become part of the mission, are a completely innovative tool for the scienceZasova said.
Each of them weighs 60 pounds. Separate in advance and enter the atmosphere separately, regardless of the vehicle of descent Russian.
The second additional element proposed by the NASA It's a atmospheric platform, that is an airplane floating in the atmosphere of Venus. Seven types of platforms have been proposed, and after being discussed by the Joint scientific work group, the option of a balloon with a variable navigation height was chosen.
The third possible addition is one or two Russian subsatites They will observe Venus, one from the side of the day and the other from the side of the night. The main objective is to explore the plasma of the solar wind and its interaction with the planet.
The scientific data of all devices will be transmitted to orbitador and from there to the land. For reception, Russian stations operating in the X band of the radio spectrum. We are also discussing the possibility of using Ka Band Americans, who will multiply the amount of information transmitted.
