This will be the longest flight of the four-stage Polar Satellite Launch Vehicle (PSLV), at two hours, 21 minutes and 62 seconds.
The PSLV-C40 will launch a total of 31 satellites including the 710-kg Cartosat-2 for earth observation, a microsatellite and a nanosatellite from India.
The 31 satellites with a combined weight of 1,323 kg have been integrated with the PSLV for deploying them in the earth's lower orbit after lift off.
The 144-foot-tall (44-meter) PSLV set for launch Friday will deliver India's Cartosat 2F mapping satellite to orbit, along with 30 secondary payloads for Indian, U.S., South Korean, British, French, Canadian, and Finnish customers. It will also be the first launch for ISRO in 2018.
# PSLV C-40 rocket launches Cartosat-2, 30 other satellites in single mission from Sriharikota. While the department of space has been speaking about allowing private players to build rockets in future, which is expected to increase the frequency of launches, Sivan said: "We're already in the process of moving it to the industry and it will take some time for it to materialize". India, too, is sending one micro and nano satellite.
The doomed August 31 mission placed India's IRNSS 1H navigation satellite into orbit, but the PSLV's payload fairing - the shroud created to protect the spacecraft during the first few minutes of flight - failed to jettison soon after liftoff. It has 31 co-passengers, including the Cartosat-2. This would be the 42nd flight of the PSLV. It will boost data services for urban and rural applications, coastal land use and regulation, monitoring of road networks, water distribution, and land-use mapping, said an HT report. The surveillance satellite from the "Cartosat 2" series will keep watch on India's hostile neighbours.
