Funds was released in 2017 to complete preliminary studies, and solicitations for instruments have been announced. its fully funded, it would be launched some time after the Mars Orbiter Mission two in the early 2020s. 


The orbiter, depending on its final configuration, would have a science payload capability of approximately 100 kilograms (220 lb) with 500 W available power.The initial elliptical orbit around the Venus is expected to have five hundred km (310 mi) at periapsis and 60,000 km (37,000 mi) at apoapsis.


Based on the success of Chandrayaan and the Mangalyaan, ISRO has been studying the feasibility of future interplanetary missions to Mars and Venus, the closest planetary neighbours to Earth. The mission concept to the Venus was first presented at a Tirupati space meet in 2012. The Government of India, in the budget for 2017–2018 gave the Department of Space a 23% increase. Under the space sciences section, the budget mentions provisions "for Mars Orbiter Mission II and Mission to Venus", and following the 2017–18 request for grants, it was authorized to complete preliminary studies. From 2016 to 2017, ISRO collaborated with JAXA to study the Venus atmosphere using signals from the Akatsuki in a radio occultation experiment.

The three broad research areas of interest for this mission include surface/subsurface features and re-surfacing processes; second: study the atmospheric chemistry, dynamics and compositional variations, and third: study the atmospheric interaction with solar radiation and solar wind.
