Venera-D » Scientific payload


Mission Venera-D includes the lander, orbiter and sub-satellite, long-living station.

One of the most important element of the mission is the lander. It will land at the surface of Venus after more than 30 years gap (the last landing on the surface of Venus - VEGA1-2 - took place in 1985).

The complex of experiments is aimed to measure the light and noble gases and its isotopes abundance, composition, chemistry and microphysics of clouds, PTW, chemical, elemental, mineralogical composition of the surface material, natural radioactive elements, and oxide state of the surface, etc. The proposed set of experiments on the lander includes: GC-MS, PTW (meteo), nephelometer and the particle sizes spectrometer, optical package, active gamma spectrometer, Mossbauer spectrometer, MTDL (Multichannel Tunable Diode Laser Spectrometer), TV-complex, containing panoramic, high resolution and descending cameras. 

The complex of experiments on the orbiter includes, among the others, several spectrometers in the spectral range from UV to MM, the mapping spectrometers, monitoring camera and the plasma package.

 Sub-satellite is aimed for joint plasma investigations, simultaneous measurement with plasma instruments on orbiter. 

Orbiter is planned to be inserted on the one day polar orbit. Landing site is preliminary chosen as one of tesseras, the oldest areas, where non- basaltic material may be found, existing before the period of high volcanic activity around 700 million years ago.
