ISRO to launch PSLV-C52 from Sriharikota on Feb 14:

Isro’s first launch of 2022 that will carry three satellites to space.

The space agency will launch the Earth Observation Satellite-04 and two rideshare payloads that include a student satellite and a mission that will lay the foundation for a future India-Bhutan Joint Satellite project.

The launch is scheduled for February 14 at 5:59 am from the First Launch Pad of Satish Dhawan Space Centre, Sriharikota.


Isro is launching three satellites into orbit that include an Earth Observation Satellite (EOS-04), student satellite INSPIREsat-1, and a technology demonstrator satellite named INS-2TD.

Earth Observation Satellite-04 is also called Radar Imagining Satellite (RISAT) that has been designed to provide high-quality images under all weather conditions for applications such as agriculture, forestry and plantations, flood mapping, soil moisture & hydrology. The spacecraft will collect observation data in C-Band completing the observations done by Resourcesat, Cartosat, and RISAt-2B series. The satellite has an operating life of a decade.

Apart from EOS-04, two other satellites hitching a ride onboard PSLV-C52 include INSAT-2TD, which is a technology demonstrator satellite that will lay the groundwork for India-Bhutan joint satellite INS-2B. The satellite has a thermal imaging camera that will help in the assessment of land, water surface temperatures, delineation of vegetation, and thermal inertia. The 17.5-kilogram satellite will remain in operation for a short duration of just six months.

The final payload is an 8.1-kilogram student satellite dubbed INSPIRESat-1 that has been developed by the Indian Institute of Space Science & Technology in association with the Laboratory of Atmospheric & Space Physics at the University of Colorado. The satellite will aim at improving our understanding of the ionosphere dynamics and the sun’s coronal heating process. Its operational lifetime is set for a year.

The 54th mission of the PSLV will see it climb up to an altitude of 529 kilometers above the Earth’s surface in the Sun Synchronous Orbit where it will deploy the Earth Observation Satellite. The PSLV is a third-generation launch vehicle designed by India which can take up to 1,750 kg of payload to Sun-Synchronous Polar Orbits of 600 km altitude.

Isro has planned five major satellite launches in the coming three months as it aims to regain its lost pace in space operations amid tough competition from China and private players like SpaceX that is conducting one launch every week in 2022. Following PSLV—C52 mission, Isro will launch OCEANSAT-3 and INS 2B ANAND on PSLV C-53 in March and SSLV-D1 Micro SAT in April 2022.
