ISRO Creates History - 104 satellites In A Single mission (14 Important Points)

Important Points

The Indian Space Research Organisation (ISRO) sets a new record in space mission achievements after it successfully launched 104 satellites in one go from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh

This was ISRO’s first space mission for the year 2017, and the most complicated mission it has ever carried out.

In about 18 minutes, all 104 satellites were released into space, each travelling at the speed of over 27,000 km per hour - 40 times the speed of an average passenger airline.

It was PSLV-C37's 39th mission.



This is the heaviest version of the PSLV, weighing about 320 tonnes at lift-off and standing tall at 44.4 meters, carrying 104 satellites (many belonging to international customers).

The main satellite is the Earth-mapping Cartosat 2 series satellite. It weighs 714 kg. Cartosat -2 will provide remote sensing services similar to that of its predecessors.


The smaller satellites belong mostly to the US (96 satellites). Other satellites belong to Israel, Kazakhstan, Netherlands, Switzerland, United Arab Emirates. Nearly 90 small satellites named 'Doves' belong to one San Francisco-based company, Planet Inc.

Two ISRO-made Nano satellites (INS-1A and INS-1B) were also launched.

The PSLV first launched the Cartosat-2 and then its 103 co-passengers into the polar Sun Synchronous Orbit, about 520 km from the Earth.


ISRO scientists used the XL Variant – the most powerful rocket – earlier used in the ambitious Chandrayaan and during the Mars Orbiter Mission (MOM).

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.

In 2014, the Russian Space Agency has launched 37 satellites in one go.

This is ISRO's second successful attempt after the launch of 23 satellites in a single rocket in June 2015.

PM Narendra Modi congratulated the scientists for successful launch, saying "this remarkable feat has made India proud".
