Context: ISRO achieved a significant milestone with its PSLV Orbital Experimental Module-3 (POEM-3) successfully re-entering Earth’s atmosphere without leaving any debris in orbit.

  • This achievement, following the PSLV-C58/XPoSat mission, is termed another milestone by ISRO.
  • The operation involved converting the final stage of the PSLV into POEM-3 and deorbiting it from 650 km to 350 km altitude.
  • This expedited re-entry process aimed to minimize risks associated with accidental break-ups.
  • POEM-3 carried nine experimental payloads, facilitating technology demonstrations and scientific experiments.


This initiative aims to safeguard orbital environments, ensuring their viability for current and future space missions.
