PRL has proposed the following instruments for Venus Orbiter Mission. These instrument have been reviewed by the expert committee and also by the APEX. The following instruments are shortlisted to be flown fly in Venus Orbiter mission.

VEDAM is a meteorological suite with additional local imaging, wind velocity and particle size measurements. VEDAM consists Meteorology Suite (MET) - Temperature, Pressure, Ambient Light/Solar Radiation, Anemometer (ANEM) - Horizontal and Vertical Wind velocities and Nephelometer (NEPH) - Size and distributions of Venus cloud particles.

This instrument will determine in-situ abundances of neutral species in the upper troposphere, Search for the presence of Sulphur and Chlorine compounds and Study of dynamics of the middle atmosphere of Venus clouds and their formation of different layers.

Knowledge of elements such as Si, O, Ca, Mg, Al, Fe, Na, K, Th help in deciphering the origin and evolution of various solar system objects such as planets, satellites, and asteroids. A Gamma-ray spectrometer (GRS) is being developed to be flown on a future missions such a measurement. laboratory model of GRS has been developed using recently developed rare earth halide scintillation crystal. For this, three crystal LaBr3:Ce, NaI(Tl), and CeBr3 have been used to detect gamma-ray photons. Our study shows that CeBr3 is a better choice compared to other scintillators particularly for estimating the concentration of K. U and Th from rock/soil.
