The EOS-03 satellite launched by the Indian Space Research Organization (ISRO) has exploded.

ISRO’s highly-anticipated launch of Earth observation satellite -3 or GISAT-1 failed after the rocket entered the lower reaches of space (an altitude of 139kms), after a flight of nearly 340seconds(5mins 40 seconds).

According to ISRO, the satellite launch was not successful and the mission failed due to engine failure.

The rocket didn’t perform as expected at the 3rd stage due to a performance anomaly in the cryogenic engine.


The EOS-3 was launched from the Satish Dhawan Space Center in Sriharikota at around 6:45 am on Thursday to monitor the Earth. Scientists at the control room said the satellite was normal in the first two phases and the cryogenic engine malfunctioned in the third phase.


GISAT a highly strategic earth observation satellite would have been placed in the geostationary orbit beyond the reach of most of the ASATs around the world, which could have given India near to 24×7 earth imaging capabilities.

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.
