However, the first and second stages of the rocket had performed normally, the Bengaluru-headquartered Indian Space Research Organisation said.
In a notification, ISRO said, “GSLV-F10 launch took place today at 0543 hrs as scheduled. Performance of first and second stages was normal. However, Cryogenic Upper Stage ignition did not happen due to technical anomaly. The mission could not be accomplished as intended.” According to ISRO, the cryogenic upper stage ignition was scheduled to take place 4.56 minutes after the lift-off. A formal announcement was also made at the Mission Control Centre by the range operations director, stating, “performance anomaly observed in the cryogenic stage. The mission could not be accomplished fully.” 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 all my friends.” ISRO, after facing hurdles caused by the pandemic, resumed its launch operations for the rocket to place the satellite with an objective to provide near real-time imaging of large areas of the country at frequent intervals and quick monitoring of natural disasters.
As the 26-hour countdown concluded on Thursday, the 51.70 metre tall rocket with four stages lifted off majestically at 05.43hrs, leaving behind a trail of thick orange coloured fumes.
The four-stage rocket was the first to carry a four-metre dia ‘Ogive Payload Fairing’ at the top of the vehicle to accommodate larger payloads. The rocket was supposed to place the EOS “an agile state-of-the-art satellite into the Geosynchronous Transfer Orbit, 19 minutes after lift-off.
GSLV failure to impact moon mission
The GSLV’s failure midway during a mission on Thursday will have its impact on India’s ambitious moon mission. India is planning a human space mission-Gaganyaan- using GSLV-MkIII rocket. The ISRO is planning to send two unmanned missions to check its rocket and the human capsule before sending its astronauts into the space. But with the failure of GSLV-F10 on Thursday due to a problem in the cryogenic engine, this will make ISRO to be doubly careful.
