ISRO to perform unique experiment in PSLV-C56 mission launched today
Indian Space Research Organisation (ISRO) has attempted a unique experiment using the fourth stage of the PSLV-C56 rocket, bringing the upper stage down to a lower orbit after successfully launching seven Singaporean satellites on Sunday. After placing the Singaporean satellites in their intended orbit at an altitude of about 536 km, the fourth stage of the PSLV rocket was placed in a lower orbit to ensure its reduced orbital life at an altitude of about 300 km.
