  • ISRO's EOS-03 will help in the quick monitoring of natural disasters like cyclones, cloudbursts, thunderstorms
  • This is the second launch for ISRO in 2021 after its successful mission in February, which was Brazil's earth observation satellite Amazonia-1 and 18 co-passenger satellites

ISRO's Earth Observation satellite (EOS-03) launched from the Satish Dhawan Space Centre on Thursday.

However, minutes after the launch, it faced a setback as the mission could not be accomplished fully due to performance anomaly in the cryogenic stage of the rocket, the space agency said on Thursday.

"GSLV-F10 lifts off successfully from Satish Dhawan Space Centre, Sriharikota," ISRO wrote a tweet.

The 51.70-metre tall rocket GSLV-F10/EOS-03 successfully lifted off from the second launch pad at the spaceport as planned at 05.43 hrs soon after the 26-hour countdown concluded.

However, Cryogenic Upper Stage ignition did not happen due to technical anomaly. The mission couldn't be accomplished as intended, the space agency added.

ISRO Chairman K Sivan said, "(The mission) could not be fully accomplished mainly because there is a technical anomaly observed in the cryogenic stage. This I wanted to tell to all my friends."

ISRO had said that EOS-03 will be capable of obtaining vital information for application in different sectors including agriculture, forestry, water bodies as well as for disaster warning, cyclone monitoring, cloudburst, or thunderstorm monitoring. It also said that earth observation satellite would provide real time images of the country and borders and also able to quick monitor of natural disasters.

This was the second launch for ISRO in 2021 after its successful mission in February, which was Brazil's earth observation satellite Amazonia-1 and 18 co-passenger satellites.

EOS-03's launch was originally planned in April or May this year but the exercise was postponed due to the second wave of the COVID-19 pandemic.

Previous launches of GSLV include the GSLV-MkIII-M1/Chandrayaan-2 mission on July 2019 while GSLV-F11 successfully placed GSAT-7A in December 2018.

The previous earth observation satellite was launched by ISRO in November 2020 onboard a polar satellite launch vehicle.

"PSLV-C49 successfully placed the EOS-01 on November 7, 2020. The mission objective was a disaster management system, earth observation. It was intended for applications in agriculture, forestry and disaster management support," ISRO said.
