About Earth Observation Satellite (EOS-04)

Launch Vehicle: It was launched by PSLV C-52 launch vehicle from the first launch pad of the Satish Dhawan Space Centre at Sriharikota.

Weight: Its weight is around 1,170 kg.

Orbit: It will be placed in a sun synchronous polar orbit of 529 km away from earth.

Feature: It is a radar-imaging satellite, designed to provide high-quality images under all weather conditions.

Applications: It includes:

  • Agriculture,
  • Forestry & plantations,
  • Soil moisture and hydrology, and
  • Flood mapping

PSLV-C52 mission: Two small satellites as co-passengers namely:

  • INSPIREsat-1: It is a student satellite from the Indian Institute of Space Science & Technology in association with the Laboratory of Atmospheric & Space Physics at the University of Colorado, Boulder and
  • INS-2TD: It is a technology demonstrator satellite from ISRO.

Recent Achievements of ISRO:

Amazonia-1:

  • It is the first dedicated commercial mission of NewSpace India Limited (NSIL), a Government of India company under Department of Space.
  • It was launched by PSLV-C51 in 2021.
  • It is a optical earth observation satellite of National Institute for Space Research (INPE), would provide remote sensing data to users for monitoring deforestation in the Amazon region and analysis of diversified agriculture across the Brazilian territory.

UNITYsat and Satish Dhawan SAT (SDSAT):

  • The PSLV-C51 launch vehicle successfully launched Indian student satellites UNITYsat and Satish Dhawan SAT (SDSAT) on February 28, 2021.
  • UNITYsat: It is intended for providing Radio relay services
  • SDSAT: It is a nano satellite intended to study the radiation levels/space weather and demonstrate long range communication technologies.

CMS-01 Mission:

  • It is India’s communication satellite was launched by PSLV-C50 in 2020.
  • It was injected into an elliptical sub-Geosynchronous Transfer Orbit.
  • It is envisaged for providing services in extended C Band frequency spectrum.

About Indian Space Research Organisation (ISRO):

  • Indian National Committee for Space Research (INCOSPAR) was set up by the Government of India in 1962.
  • Indian Space Research Organisation, formed in 1969, superseded the erstwhile INCOSPAR.
  • Vikram Sarabhai played a significant role in identifying the role and importance of space technology in a Nation’s development.
  • It aims to Harness space technology for national development, while pursuing space science research and planetary exploration.
  • Recently, S. Somanath, an eminent rocket scientist has been appointed as the Chairman of the Indian Space Research Organisation (ISRO) and the Space Secretary.
