Indian Space Research Organisation (ISRO) launched a record 104 satellites in one go on Wednesday, 15th February 2017 (9.28 am), on board a single rocket from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The PSLV-C37/Cartosat2 Series satellite mission includes international payloads. The Polar Satellite Launch Vehicle (PSLV) C 37 includes 101 nano-satellites (weighing below 10 kilograms each) from five countries- the United States, Netherlands, Israel, Kazakhstan and Switzerland, along with a couple of Indian nano-satellites and a heavy Cartosat. The PSLV has a payload capacity of more than 1,500 kilos, but it carried only 1,360 on this mission.
The mission- PSLV first launched the 714 kg Carosat-2 Series satellite for the earth observation followed by two nano satellites INS-1A and INS-1B, after it reached the polar Sun Synchronous Orbit, about 520 km from Earth. It then went on to inject 103 co-passenger satellites, together weighing about 664 kg, in pairs.
ISRO scientists used the XL Variant – the most powerful rocket – earlier used in the ambitious Chandrayaan and during the Mars Orbiter Mission (MOM).

What is significant about the launch is the number of satellites carried by a rocket. Compared to successful launch by the Russian Space Agency launching 37 satellites in one go, India became the first country to script history by launching 104 satellites in a single rocket!
