On PSLV-C58/XPoSat campaign, POEM-3 hosted ten payloads weighing ~145 kg cumulatively.[4] PSLV fourth stage was lowered to 350 km orbit at 9.6° inclination after deploying XPoSat to reach the POEM-3 operational orbit. For power generation and storage it will again have flexible solar panels in conjunction with 50Ah Li-Ion battery and will be three-axis stabilized.[5] Payloads hosted on POEM-3 are following, seven of them facilitated by IN-SPACe and three are by ISRO,
Radiation Shielding Experimental Module (RSEM): Experimental payload by TakeMe2Space to evaluate effectiveness of Tantalum coating for radiation shielding.
Fuel cell Power System (FCPS): Demonstration of fuel cell power system by VSSC
Si-based High Energy cell: Demonstration of Silicon based High Energy cells by VSSC
Two instruments from VSSC consist of twin sets of "Fuel Cell Power System (FCPS)' designed to demonstrate fuel cell technology and Silicon-based high-energy cells which can be later be used on large scale missions such as the proposed Indian Space Station,[9] for which preliminary sources in the media indicated would be the case. On the other hand, the payload from PRL, known as the Dust Experiment (DEX), aims to quantify interplanetary dust within the low earth orbit regime.[3]
POEM-3 later re-entered the earth's atmosphere having completed all mission objectives by the beginning of February, over the Pacific Ocean on March 21st.[10][11][12]
