ISRO succeeds in 100th mission, launches 31 satellites in orbit

PSLV ISRO

In a milestone event in the country's space history, the Indian Space Research Organisation (ISRO) today launched its 100th satellite along-with 30 others in a single mission. On its 42nd mission, ISRO's trusted workhorse "PSLV-C40" carried the weather observation "Cartosat-2" series satellite, which was successfully put in earth's orbit.

Out of the 31, three are Indian and 28 are from six countries: Canada, Finland, France, South Korea, UK and the US.

After the failure of the IRNSS-1H in august, previous year because of some technical accidents, the Polar Satellite Launch Vehicle or PSLV has taken a lift off at 9.29 am, today, from Sriharikota in Andhra Pradesh, and is carrying India's 100th satellite.

This will be ISRO's first launch in 2018 and also the first after the unsuccessful mission of IRNSS-1H in August past year. The satellites have been placed into a 505 km polar sun-synchronous orbit.

Cartosat-2 Series is an advanced remote sensing satellite similar in configuration to earlier six spacecraft in the series and meant to augment data services to the users.

On August 31, India's mission to launch its backup navigation satellite IRNSS-1H on board PSLV-C39 failed after a technical fault on the final leg following a ideal launch.

Roughly around 45 minutes later, the rocket would eject its 31st satellite - Isro's Microsat - in the second orbit at an altitude of 359km.

"This is a very special moment for ISRO", said K Sivan after the launch was deemed successful. This mission had lasted two hours and 15 minutes, ISRO scientists said.

India will use its latest satellites for better border surveillance and obtaining high resolution images of the earth. In this context, ISRO has taken four-month interval to revisit some of the core areas.
