The PSLV Orbital Experimental Module (POEM) is a creative project by ISRO (Indian Space Research Organisation).
It takes a part of a rocket that was usually thrown away – the fourth stage of the PSLV rocket – and turns it into a space lab.
This space lab, or platform, is used for scientific experiments in space.
The Innovation in POEM:
Usually, the fourth stage of a rocket (in this case, PSLV) is discarded after launching satellites.
ISRO’s idea was to keep using this stage as a floating lab in space.
This idea was first put into action in June 2022 during the PSLV-C53/DS-EO mission.
About POEM-3:
POEM-3 is the third version of this space lab.
It’s special because it can control its position in all three directions in space.
It can also make its own power and send and receive messages from Earth.
On January 1, 2024, POEM-3 launched a satellite named XPoSat and did everything it was supposed to do successfully.
How Long Will It Stay in Space?
POEM-3 will stay in space for about 73 more days.
After this time, it will come back into the Earth’s atmosphere.
In simple terms, POEM is like turning a part of a used rocket into a temporary space station for experiments, instead of letting it go to waste.
