These missions focused on studying Venus’ atmospheric circulation, climate, and surface features. However, they were limited to the southern polar region or some narrow areas near the equator. Therefore, a comprehensive topographic map of Venus could not be created, taking into account factors like winds, waves, and chemical abundance. ISRO has planned to send 19 payloads to Venus, which will provide uniform coverage of the planet and create a unique dataset for future missions. Out of these 19 payloads, 16 will be entirely indigenous, one will be developed in collaboration with Sweden, one with Germany, and one from Russia.
ISRO’s Venus Mission to Send 19 Payloads
Venus Express and Akatsuki missions studied Venus’ atmospheric dynamics, climate, and surface features. ISRO’s Venus mission will create a topographic map of the planet, which was not possible earlier due to limitations in the previous missions. This mission will provide a comprehensive understanding of Venus.
Details of Temperature and Brightness Will Be Obtained
The VSAR (Venus Synthetic Aperture Radar) payload will detect active volcanoes or volcanic hotspots on Venus. It will also map Venus’ craters and the ejecta produced by them. In radiometer mode, it will provide information about Venus’ brightness and temperature. The VSEAM (Venus Surface Emissivity and Atmospheric Mapper) payload will identify active volcanic hotspots using thermal imaging and atmospheric studies. It will also map Venus’ clouds and aerosols.
