The Indian Space Research Organisation (ISRO) has successfully demonstrated the PSLV Orbital Experimental Module (POEM) in recent space missions. Which of the following statements regarding the technical features and operational role of POEM are correct?
- It converts the spent fourth stage (PS4) of the Polar Satellite Launch Vehicle into a stabilized in-orbit platform for scientific experiments.Cevap
- BIt is designed as an atmospheric reentry capsule equipped with heat shielding to return scientific payloads safely back to Earth.
- It generates electrical power using solar panels mounted on the PS4 tank combined with a Lithium-ion battery system.Cevap
- DIt depends continuously on the main liquid propulsion engines of the PS4 stage to maintain active three-axis attitude stabilization.
Cevap
The correct statements are that POEM converts the spent fourth stage (PS4) of the Polar Satellite Launch Vehicle into a stabilized in-orbit platform for scientific experiments, and that it generates electrical power using solar panels mounted on the PS4 tank combined with a Lithium-ion battery system.
The PSLV Orbital Experimental Module (POEM) repurposes the spent fourth stage (PS4) of the PSLV rocket into a functional orbital experimental platform after primary payload separation. Power is generated using solar panels wrapped around the propellant tank together with a Lithium-ion battery pack, while 3-axis attitude control is maintained using cold-gas helium thrusters and reaction wheels.
