ISRO sets new record in the world of space mission

The Indian Space Research Organization (ISRO) has created a record in the world of space mission achievements, after it successfully launched 104 satellites in one go today from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.

For the year 2017 the launch was ISRO’s first space mission, and the most complicated mission the organization has ever carried out. PM Narendra Modi and the President  Pranab Mukherjee congratulated the space organization of the proud event and significant boost to the country’s space program.

The space agency began the countdown for the launch of the Polar Satellite Launch Vehicle (PSLV)’s 39th flight on Tuesday (14th February) after the Mission Readiness Review committee and Launch Authorisation Board gave its approval for lift off, ISRO said.


The PSLV-C37/Cartosat2 Series satellite mission included the primary satellite (Cartosat-2) and 101 international nano satellites. It also launched two of its own nano satellites, INS-1A and INS-1B.


PSLV first launched the 714 kg Cartosat-2 Series satellite for earth observation, followed by the INS-1A and INS-1B, after it reached the polar Sun Synchronous Orbit. 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).
