The 42nd Polar Satellite Launch Vehicle (PSLV), PSLV-C40, was launched successfully on 11 January 2018 by the Indian Space Research Organisation (ISRO) from the First Launch Pad of the Satish Dhawan Space Centre (SDSC) in Sriharikota and it placed 31 satellites across two orbits.
The PSLV, launched at 9.29 a.m., had as its primary payload the country’s fourth satellite in the remote sensing Cartosat-2 series, weighing 710 kg. The 30 other co-passenger smaller satellites, together weigh 613 kg. Of them, 28 are from other countries.
The Cartosat-2, whose imagery will be used to develop various land and geographical information system applications, was placed in a circular polar sun synchronous orbit 505 km from the Earth. The satellite’s design life is five years.
Of the 28 foreign satellites, launched as part of deals made by ISRO’s commercial arm Antrix Corporation Limited, three were microsatellites and 25 nanosatellites. There were 19 satellites from the United States and five from South Korea. The United Kingdom, France, Canada and Finland had a satellite each.
