POEM-3, which stands for Polar Satellite Launch Vehicle Orbital Experimental Module-3, was an integral part of the PSLV-C58/XPoSat mission. This module served as a stabilized platform aimed at conducting various experiments in space after deploying satellites into their designated orbits.
The controlled re-entry of POEM-3 into Earth's atmosphere was a deliberate action taken to minimize the creation of orbital debris. This decision aligns with responsible space exploration practices, focusing on mitigating the risks associated with space debris.
POEM-3 was deorbited from an altitude of 650 km to 350 km, facilitating an early re-entry. Furthermore, the module underwent passivation to eliminate any remaining propellants, significantly reducing the chances of accidental break-ups during re-entry.
Equipped with nine different experimental payloads, POEM-3 carried out a variety of technology demonstrations and scientific experiments. Notably, six of these payloads were provided by non-governmental entities, showcasing innovative developments in indigenous systems.
The payloads for POEM-3 were contributed by startups, universities, and non-governmental organizations. This initiative was part of the Indian National Space Promotion and Authorisation Centre (IN-SPACe), which aims to promote innovation and collaboration within academia and the private sector.
The POEM platform provides a cost-effective opportunity for executing short-duration space experiments. It facilitates innovation and collaboration, allowing academic institutions and private entities to test new technologies and conduct scientific research in the unique environment of space.
ISRO actively demonstrates its commitment to responsible space operations by implementing strategies to mitigate orbital debris. This includes controlled re-entry missions such as POEM-3 and other initiatives aimed at ensuring a sustainable environment for future space endeavors.
Q1. What is the primary purpose of POEM-3?
Answer: The primary purpose of POEM-3 is to serve as a platform for conducting various space experiments and technology demonstrations after satellites are deployed into orbit.
Q2. How does controlled re-entry help in space exploration?
Answer: Controlled re-entry helps minimize orbital debris, reducing the risks associated with space junk and ensuring responsible space exploration practices.
Q3. What types of organizations contributed to POEM-3's payloads?
