The Indian Space Research Organisation (ISRO) on 12 January 2018 launched 31 satellites along with Cartosat-2 satellite on its 44.4-metre tall Polar Satellite Launch Vehicle (PSLV-C40) rocket. The polar rocket was launched from Sriharikota, Andhra Pradesh.

The 320-tonne rocket will place the satellites one-by-one and deploy them into the earth's lower orbit. The entire lift-off process along with the process of placing the satellites in two orbits will take the satellite 2 hours and 21 minutes. It will be the longest flight time of the PSLV C40.

PSLV-C40 successfully placed the Cartosat-2 series satellite into sun synchronous orbit.

31 Satellites launched

• Among 31 satellites, three satellites belong to India and 28 are of six other countries.

• The Indian satellites are 710 kg Cartosat-2 series, a 100 kg micro satellite and a 5 kg nano satellite.
