After launching main satellite tv for pc XPoSat, the fourth rocket stage (PS4), additionally referred to as PSLV Orbital Experimental Module-3 (POEM-3), allowed 9 totally different payloads to hold out expertise demonstrations and scientific experiments in zero gravity in house.By late Jan 2024, POEM-3 achieved all its mission objectives, and the one goal that remained to be fulfilled was an atmospheric re-entry. On March 21, POEM-3 made a fiery re-entry to the Earth’s environment and is believed to have splashed down into the North Pacific Ocean at 7.34 pm IST, the company stated.
PSLV-C58 is the third such mission within the sequence the place the fourth stage of the rocket was used as an experimental platform (POEM), scripting success every time.
By the POEM, which serves as a really cost-effective platform for finishing up short-duration space-borne experiments, Isro has opened up new vistas for academia, startups and NGEs to hold out house experiments with their new payloads. This chance has been successfully utilized by quite a few startups, universities and NGEs for finishing up experiments in house, which included electrical thrusters, satellite tv for pc dispensers, and star-tracking. Out of the 9 payloads, six had been delivered by non-governmental entities (NGEs) by means of house regulator IN-SPACe. The mission targets of those payloads had been met in a month.

The stage was de-orbited from 650 km to 350 km, which facilitated its early re-entry and was passivated to take away residual propellants to minimise any unintended break-up dangers.
The orbital altitude of the higher stage continued to decay below the affect of pure forces, primarily atmospheric drag with the module (NORAD ID 58695) anticipated to have impacted the North Pacific Ocean (Lat 6.4 N & Lengthy 158.7 W) on March 21, 2024, at 14:04 UTC (19:34 Hrs. IST), Isro stated. Until close to re-entry, POEM-3 was tracked by Isro’s ISTRAC floor stations. The Multi-Object Monitoring Radar at Sriharikota additionally tracked the fourth stage (PS4 stage) return to the Earth.
Isro stated it should proceed its dedication to offering an economical orbital experiment platform.
