India has created a new history in the space sector today. The Indian Space Research Organization (ISRO) has launched 7 satellites simultaneously on Sunday i.e. July 30.This includes 1 indigenous and 6 satellites of Singapore. These satellites were launched from Sriharikota in Andhra Pradesh on a PSLI-C56 rocket. Pslv-C56, the commercial arm of ISRO, is a mission of New Space India Limited.After successfully launching seven Singapore satellites, ISRO scientists are now starting a new experiment using the fourth stage of the PSLV-C56 rocket. In the PSLV-C55 TeLEOS-2 mission launched in April this year, today scientists will attempt to put the fourth stage of the PSLV rocket into a lower orbit.According to ISRO, after placing all the Singapore satellites in the intended orbit at an altitude of about 536 km, the upper stage of the rocket will be placed in the lower orbit to ensure its short orbital life at an altitude of about 300 km.”PS4 (Stage IV) will be placed in a circular lower Earth orbit at 300×300 km, using leftover propellant to reduce the orbital life of spent PS4 phase,” ISRO said. ‘
