Indian Space Research Organisation’s (Isro) Geosynchronous Satellite Launch Vehicle-F10 (GSLV-F10) failed to place the Earth observation satellite EOS-03 in its geosynchronous orbit due to technical anomalies during one of the operational stages.
Isro said the mission to put the EOS-03 – also called Geo Imaging Satellite-1 (GISAT-1) - in its orbit 'could not be accomplished fully' due to technical anomalies during one of the operational stages.
According to the latest update from the space agency, the EOS satellite is out of its trajectory path as its cryogenic engine also failed to lift the satellite to its geostationary orbit.
The rocket carrying EOS-03 took off from the second launch pad of the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota as scheduled at 0543 hrs on Thursday but it failed to place the satellite in its geosynchronous transfer orbit.
"The mission could not be fully accomplished mainly because there was a technical anomaly observed in the cryogenic stage. This, I want to tell to all my friends (sic)," ISRO chief K Sivan said after the launch.
"GSLV-F10 /EOS03 mission 'cannot be accomplished fully' due to a performance anomaly in the cryogenic stage," ISRO said. "GSLV-F10 launch took place today at 0543 Hrs IST as scheduled. Performance of the first and second stages was normal. However, Cryogenic Upper Stage ignition did not happen due to technical anomaly. The mission couldn't be accomplished as intended," the space agency said in a tweet.
EOS-03, a state-of-the-art agile Earth observation satellite, was to be India’s eye on the sky.
A 4-metre diameter Ogive shaped payload fairing was also flown for the first time in this GSLV flight. This is the fourteenth flight of GSLV.
