ISRO launches India’s first hyperspectral imaging satellite; carries 30 foreign satellites too.

Indian Space Research Organisation’s PSLV C 43 was launched from Sriharikota. It carried India’s first hyperspectral imaging satellite (HysIS), an advanced earth observation satellite, and 30 foreign satellites.

In an mission lasting close to 112-minutes PSLV C43 has delivered India’s primary satellite into the polar sun-synchronous orbit and is now in the process of delivering 30 international co-passengers satellites.

In PSLV also carried India’s first full-fledged hyperspectral imaging satellite (HysIS) was also launched. This will be used for a range of applications like agriculture, forestry, soil survey, geology, coastal zones, inland water studies, environmental studies and detection of pollution from industries. Being an earth observation satellite, it will also be used by the military for surveillance purpose.

The 30 commercial satellites, including one micro and 29 nano satellites, are from eight countries. 23 of the satellites are from US, while its the first time an Indian vehicle is carrying satellites from Australia, Colombia, Malaysia and Spain.

HysIS, which can see in 55 spectral or colour bands from 630 km above the ground, carries two payloads. One to capture images in the visible near-infrared (VNIR) range of the light spectrum and another in the shortwave infrared (SWIR) range. The satellite is designed to provide earth observation service for five years till 2023.

PSLVC43 is a four-stage rocket, with alternating liquid and solid stages. This PSLV variant is the lightest version of the PSLV rocket – the core-alone version – that only uses four core stages without six strap-on boosters. Boosters give added thrust to other two PSLV variants. Each stage is built to power the rocket through a different phase in the launch process.

This launch was PSLV’s 45th mission overall and 13th of PSLV C43 variant. In the last 25 years, Isro has launched 52 Indian and 239 foreign satellites from 28 countries, carving a space for itself in the satellite launch market
