PSLV's POEM-3 Mission: Mapping Earth's Magnetic Field



  Mar 28, 2024

SLV’s POEM-3 Mission



1. What is POEM-3?

POEM-3, standing for Polar Satellite Launch Vehicle Orbital Experimental Module-3, was a part of the PSLV-C58/XPoSat mission. It served as a stabilised platform for conducting experiments in space, following the deployment of satellites into their intended orbits.

2. Why was the POEM-3 re-entered into Earth’s atmosphere?

The POEM-3 was deliberately brought back to Earth to ensure minimal orbital debris, adhering to responsible space exploration practices. This controlled re-entry was aimed at mitigating risks associated with space debris.

3. How was POEM-3 deorbited?

The module was deorbited from an altitude of 650km to 350km, which facilitated its early re-entry. Additionally, it was passivated to remove residual propellants, reducing the risk of accidental break-ups.

4. What experiments did POEM-3 conduct?

POEM-3 carried out various technology demonstrations and scientific experiments. It was equipped with nine different experimental payloads for these purposes, six of which were delivered by non-governmental entities. These experiments included tests on newly developed indigenous systems.

5. Who contributed to the payloads on POEM-3?

The payloads for POEM-3 were contributed by startups, universities, and non-governmental entities. This was part of the Indian National Space Promotion and Authorisation Centre (IN-SPACe) initiative, aiming to foster innovation and collaboration with academia and private entities.

6. What does the POEM platform offer?

The POEM platform offers a cost-effective opportunity for conducting short-duration space experiments. It facilitates innovation and collaboration with academia and private entities, enabling them to test new technologies and conduct scientific research in space.

7. How does ISRO address the issue of orbital debris?

ISRO demonstrates its commitment to responsible space operations by implementing measures to mitigate orbital debris. This includes controlled re-entry missions like POEM-3 and other initiatives aimed at ensuring a sustainable environment for future space endeavors.
