Interesting news item from The Asian Age:


Quick summary - looks like it's only a feasibility study, so I don't know how far it has gone along the planning and proposal process. But the veteran French planetary balloon proponent Jacques Blamont has been working with Indians on the plans, and one or more balloons in the atmosphere are part of the mission plan.


... because the Solar System ain't gonna map itself.

The AO lists the total scientific payload as ~100 kg, presumably to be divided between the Indian instruments listed as selected in the AO (see below) and any foreign contributions. By comparison, the 2016 EnVision proposed mission's radar unit would have been 176 kg, it's Venus Emissivity Mapper at 14 kg.

Listed instruments to be provided by India:

1. S-Band Synthetic Aperture Radar (SAR)
2. Advanced Radar for Topside Ionosphere and subsurface sounding
3. Ultra Violet (UV) Imaging Spectroscopy Telescope
4. Thermal Camera
5. Cloud Monitoring Camera
6. Venus Atmospheric SpectroPolarimeter
7. Airglow photometer
8. Radio Occultation Experiment
9. Ionospheric Electron Temperature Analyser
10. Retarding Potential Analyser
11. Mass Spectrometer
12. Plasma Wave Detector (Langmuir Probe, Electric Field Sensor and Magnetometer)

The elliptical orbit, initially 500 x 60,000 km, likely will limit the highest resolution imaging by the SAR to the latitude of periapsis.
