## UNSTARRED QUESTION NO. 2375 LAUNCH OF SATELLITE EOS-4

## 2375.  SHRI RAVNEET SINGH BITTU:

Will the PRIME MINISTER be pleased to state:

- (a) whether it is a fact that the Indian Space Research Organisation (ISRO) has recently launched an earth observation  satellite  EOS-4  along  with  two  other  scientific satellites;
- (b)
- if so, the details thereof;
- the details of the likely benefits to be accrued for agriculture, mapping,  soil  moisture  and  hydrology  by
- (c) forestry, flood launching of these satellites;
- (d) the details of delays, if any, in all the big ticket missions and other routine launches by ISRO scheduled during the last two years along with the reasons therefor; and
- (e) the details of the steps taken by the Government to ensure the  early  operationalisation  of  all  delayed  space  missions along  with  the  schedule  of  future  satellite  launches  in  the next two years?

## 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-04  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 524.87 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  all  weather  &  day/night  imaging.  INS2TD  is  the  first  satellite  of  the  2 nd   generation  nano-satellite 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.

- (c) The  data  from  EOS-4  will  be  helpful  for  applications  in  the domains of agriculture, forestry, flood mapping, soil moisture and  hydrology.  The  likely  benefits  to  be  accrued  in  these domains include assessment of inventory of crops & multiple in-season crop production forecast, early assessment of long duration  kharif  crops,  assessment  of  forest  disturbance  &
- forest biomass, advisories on crop-water requirements, monitoring of flood-inundated areas, all-season assessment of surface water spread, reservoir capacity, irrigation performance etc.
- (d) The  big  ticket  missions  and  other  routine  launches  by  ISRO were badly impacted in the last 2 years due to the prevailing COVID-19  situation  in  the  country.  ISRO  Centres  as  well  as industries  were  not  fully  operational  due  to  imposition  of lockdowns and other restrictions at different times in different cities. Further, global and domestic supply chain was disrupted  which  also  impacted  the  scheduled  missions  of ISRO. This has resulted in significant delays to key missions including  CHANDRAYAAN-3,  GAGANYAAN  and  other  routine missions including EOS-4, EOS-6.
- (e) ISRO has been trying to compensate for the delays by taking a number  of  steps  that  includes  prioritisation  of  resources  for key  missions  such  as  CHANDRAYAAN-3,  GAGANYAAN  etc. These efforts have resulted in the recent successful launch of EOS-4 on the PSLV C-52 mission. It is expected that missions including  EOS-06,  NVS-01  would  be  successfully  completed during the year 2022-23 in addition to other key missions.

For the coming two years, initiatives are also being undertaken for various other prestigious missions that includes ADITYA-L1, Technology Demonstration Satellite, XPOSAT.
