Context: The Indian Space Research Organisation (ISRO) on Saturday informed that the space agency has performed all experiments in Payload Orbital Experiment for Microgravity (POEM-3) mission launched.

PSLV Orbital Experimental Module-3 (POEM-3) 

  • About: It is India's cost-effective space platform created from the spent PS4 stage of the PSLV-C58 vehicle, which successfully launched XPoSat on January 1, 2024.
  • Launched by: PSLV-C58 vehicle
  • Objectives: Deploying XPoSat into a 650 km orbit, followed by a descent to a 350 km circular orbit to minimize orbit decay time post-experiment completion. 
  • It is a three-axis-attitude controlled platform equipped with power generation, telecommand & telemetry capabilities to support various payloads.
  • Orbital: By its 25th day in orbit, POEM-3 completed 400 orbits and currently orbits at approximately 322 km by 352 km. 
  • Payload Operations: POEM-3 carried nine payloads from VSSC, PRL, Academia, and Space start-ups through IN-SPACe. All payloads, including ARKA200, RUDRA, LEAP-TD, WeSAT, BeliefSat0, RSEM, DEX, 100 W Fuel Cell Power System, and Si-C based High Power Li-Ion Battery, met their objectives with data collection during every orbit.
  • Debris-Free Mission: With POEM-3's anticipated orbital decay and re-entry in three months, the PSLV-C58 XPoSat mission stands out for leaving zero debris in space, contributing to responsible space exploration practices.
