The Indian Space Research Organisation (ISRO) said on Monday that the XPoSat mission – launched on January 1 – practically left zero debris in orbit.</p><p>The module is expected to have fallen in the north Pacific Ocean at about 7:34 pm IST on March 21.</p><p>After the primary XPoSat mission of injecting all satellites into intended orbits, POEM-3 used the spent fourth stage of the PSLV-C58 vehicle as a platform with nine experimental payloads to conduct technology demonstrations and scientific experiments. Six of these payloads were delivered by non-government entities (NGEs).
