## ANSWER

## MINISTER OF STATE IN THE MINISTRY OF PERSONNEL, PG & PENSIONS AND IN THE PRIME MINISTER'S OFFICE (DR. JITENDRA SINGH):

## (a) & (b)

Yes Sir, ISRO has successfully launched the earth observation satellite  EOS-4  onboard  PSLV-C52  on  14 th   February,  2022  at 05:59 hrs IST from Satish Dhawan Space Centre, Sriharikota, along  with  INS-2TD  &  INSPIRESat-1  as  co-passengers.  The Satellites were injected into the polar sun synchronous orbit at 524.84 km altitude.

EOS-4 is a Synthetic Aperture Radar (SAR) imaging satellite for Earth Observation, operating in C-band at 5.4 GHz frequency, for applications in the domains of agriculture, disaster management, water resources and forestry.

INS-2TD is the first satellite of the 2 nd generation nanosatellites intended to demonstrate indigenously developed Nano systems for in-orbit performance.

INSPIRESat-1  is  a  student  satellite  of  the  class  9U,  jointly developed by Indian Institute of Space Science and Technology (IIST),  Thiruvananthapuram, India and Laboratory of Space Physics, University of Colorado, Boulder, the USA, to study  the  Ionosphere  dynamics  and  sun's  coronal  heating processes. (c) Currently,  the  satellites  are  undergoing  various  in-orbit  tests and  calibrations.  Subsequently,  the  data  available  from  the satellites  will  be  used  for  achieving  the  mission  objectives, during the designated mission life. (d) The total time taken to realize the satellite is 63 months from date of financial sanction and the expenditure towards realization of satellite is nearly Rs. 490 crore. (e) No, Sir. (f) 7  satellites  are  likely  to  be  launched  by  ISRO  during  the current year.
