Sriharikota: PSLV-C43 rocket carrying India best ever high-resolution earth imaging satellite HysIS (Hyperspectral Imaging Satellite) launched by ISRO. the workhorse rocket also bears 30 small co-passenger satellites from eight different countries, mostly belonging to the United States.
In Andhra Pradesh Sriharikota, the 45th flight of the PSLV was launched from the Satish Dhawan Space Centre and in two different orbits, the Polar Satellite Launch Vehicle will place 31 satellites. The last stage of the rocket will be reignited twice for it to come down to 504 Km after the Indian satellite is positioned in an orbit 636 km over the earth, and then release the smaller satellites. The entire process will extend over 112 minutes.
ISRO further mentioned that “HysIS is an earth observation satellite developed by ISRO. It is the primary satellite of the PSLV-C43 mission whose lifespan is five years. With an inclination of 97.957 deg the satellite will be placed in 636 km polar sun-synchronous orbit (SSO).”
The Space agency added the primary goal of HysIS is to study the earth surface in visible, near infrared and shortwave infrared regions of the electromagnetic spectrum.
On February 15, 2017, The Space Research Organisation (ISRO) holds the record for launching the highest number of satellites in a single mission-104.
ISRO Chairman Dr. K Sivan, “The PSLV’s is the main passenger, called ‘Chhota Bheem’ after a popular cartoon character, weighs a relatively low 380 kg. However, HysIS is a very rare satellite with a super- sharp eye, and very few countries have indigenously mastered this technology. Many countries are trying to send such hyperspectral cameras into space but interpreting its results is not easy. “
The Space Agency also mentions that the co-passengers of HysIS include one Micro and 29 Nanosatellites from eight different countries. PSLV-C43 will be placed these satellites in a 504 km orbit.
