The applicants must be equipped to submit proposals as PIs for specific target observations with necessary scientific and technical justification and can analyse the data, if the target is observed based on approvals, Isro said, adding that in the twelfth cycle, “55% of observing time is available for Indian proposals and 20% of observing time is for International proposals” and that the rest of the time in this cycle is allotted for calibration, targets of opportunity and the “AstroSat long term key proposals (ALTKP).

AstroSat is the first dedicated Indian astronomy mission aimed at studying celestial sources in X-ray and UV spectral bands simultaneously. The satellite is at 650km near-equatorial orbit with six-degree orbital inclination.

AstroSat completed six years in orbit at the end of September 2021 and currently the eleventh cycle proposals are being executed. And, observations for the twelfth cycle will be carried out between October, 2022 to September 2023.
