India to launch its 100th satellite on 12 January along with 30 other satellites from six countries

The Polar Satellite Launch Vehicle (PSLV) will also be ISRO's 40th space mission. The total weight of all the 31 satellites will be about 1,323 kg.

India would be launching its 100th satellite into space on 12 January along with 30 other satellites, including 28 from six other countries from its spaceport at Sriharikota in Andhra Pradesh, said a top space agency official on 9 January.

"Of the three Indian spacecraft being launched on January 12, — the 100 kg microsatellite will be the 100th that will be ejected out of the rocket last into the earth's orbit," Indian Space Research Organisation (ISRO) Satellite Centre Director M Annadurai told IANS.

The other two Indian satellites are 710 kg Cartosat in 2 series for earth observation and a 5 kg nanosatellite.

"With these three satellites, ISRO would have sent 100 satellites into the space. We are all eagerly waiting for that. It will be a maiden century," said Annadurai, on the sidelines of a space expo in the city.

The Polar Satellite Launch Vehicle (PSLV) will also be ISRO's 40th space mission.

The PSLV-C40 will launch on 12 January at 9.28 am with three microsatellites and 25 nanosatellites belonging to Canada, Finland, France, South Korea, Britain and the US.

The total weight of all the 31 satellites that will be carried is about 1,323 kg.

The first space mission in 2018 on board the PSLV-C40 comes four months after a similar rocket failed to deliver the country's eighth navigation satellite in the earth's lower orbit on 31 August.

"The PSLV had a very successful run upto its 39th mission (PSLV-C39), which was a setback as the heat shield failed to separate," Annadurai said, adding that the ISRO was holding tests to ensure that the problem does not recur in this mission.

"We have studied in detail as to what could have gone wrong and are making sure it does not repeat. With PSLV-C40, we are back in the game," he said.

As an observational satellite, Cartosat will beam high-quality images for cartographic, urban and rural applications, coastal land use and regulation and utility management like road network monitoring.

The space agency plans to have at least one launch a month in this year.

ISRO will also be launching its second lunar mission (Chandrayaan-2) to the moon, with an orbiter, lander and rover for the first time.
