On Monday morning, the Indian Space Research Organisation (ISRO) launched the PSLV-C45 rocket that carried one Indian and 28 international satellites into space. Like many of ISRO’s earlier missions, the launch of PSLV-C45 was special for unique features that were successfully tried out for the first time. First, it was the first time ISRO launched a rocket that injected satellites in three different orbits. And what is the significance of using the fourth stage as a satellite? The fourth stage will not have the usual life of a satellite.
