ISRO launches Earth Observation Satellite, two co-passenger satellites

Sriharikota: The Indian Space Research Organisation (ISRO) launched a Polar Satellite Launch Vehicle with two smaller co-passenger satellites today at at 05.59 am.

Radar Imaging Satellite and two other had launched from the First Launch Pad of Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh.

India’s Polar Satellite Launch Vehicle PSLV-C52 injected Earth Observation Satellite EOS-04, into an intended sun synchronous polar orbit of 529 km altitude at 06:17 hours IST on February 14, 2022 from Satish Dhawan Space Centre, SHAR, Sriharikota, ISRO tweeted soon after successfully launched.

The two smaller co-passenger satellites include a student satellite (INSPIREsat-1) from Indian Institute of Space Science and Technology (IIST) in association with Laboratory of Atmospheric and Space Physics at University of Colorado, Boulder. It is also contributed by NTU, Singapore and NCU, Taiwan.

Two scientific payloads in this satellite is to improve the understanding of ionosphere dynamics and sun's coronal heating processes, NDTV reports.

Amid cheers in Mission Control, the launch director announced that all three satellites were successfully deployed. Following the launch, Isro chief S Somnath said, "The mission of PSLV-C52 has been successfully accomplished."

The Earth Observation Satellite-04 is also called Radar Imaging 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.

The Indian Space Research Organisation  (ISRO)'s previous launch in this series, EOS-03, suffered a failure during liftoff in August 2021. ISRO later said the cause was "a failure to ignite the cryogenic stage of the launch vehicle,"
