India has launched just three planetary-science spacecraft, but the country is already eyeing a new destination: Venus.

Scientists and engineers at the Indian Space Research Organisation (ISRO) have sent plans for a Venus orbiter to the Indian national government and are hoping they’ll get approval to go ahead with the mission. The spacecraft could launch in just a few years and would carry more than a dozen instruments.

“The major objective is to map the Venusian surface and subsurface,” Nigar Shaji, an ISRO scientist, told a group of Venus experts during a meeting held this week in Colorado.

According to Shaji, the Venus orbiter that ISRO is designing would be able to create such a dataset for Venus in about a year. In addition to mapping the surface itself, looking a bit deeper into the planet should help scientists identify volcanic hotspots scattered across Venus.

Instruments on board the spacecraft would also study the planet’s atmosphere and ionosphere, as well as how Venus interacts with the surrounding environment, Shaji said. ISRO has identified 16 instruments from Indian scientists that it would like to fly. Those include instruments focused on monitoring clouds, identifying lightning strikes, studying the eerie airglow of the planet and measuring the highly charged plasma particles passing by Venus on their way out from the sun.
