GSLV-F10/EOS-03 mission’s purpose was to acquire near real-time images of large areas at frequent intervals, to monitor natural disasters, episodic events and get spectral signatures for agriculture, forestry.
Sriharikota: The Indian Space Research Organisation (ISRO) said on Thursday that its second mission of the year to place Earth Observation satellite (EOS-03) using a Geosynchronous Satellite Launch Vehicle (GSLV) rocket has been hampered by a performance anomaly in the cryogenic stage of the rocket.
Soon after the 26-hour countdown concluded, the 51.70-meter-tall rocket GSLV-F10/EOS-03 lifted off as scheduled at 05.43 hrs from the second launch pad at the Satish Dhawan Space Centre, Sriharikota.
In preparation for lift-off, the Launch Authorisation Board cleared the decks, as planned.
Scientists at the Mission Control Centre reported the rocket’s performance in its first and second stages was normal.
A few minutes later, the scientists were seen discussing and the Range Operations Director announced in the Mission Control Centre that the “mission could not be accomplished fully due to performance anomaly”.
“Performance anomaly observed in the cryogenic stage. The mission could not be accomplished fully,” the Range Operations Director announced.
ISRO chairman K Sivan later 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.”
Meanwhile, ISRO tweeted: “GSLV-F10 launch took place today at 0543 Hrs IST as scheduled. Performance of 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.”
Originally, Thursday’s launch would have taken place in April or May, but the COVID-19 pandemic forced the scientists to push back the date to August.
Currently, India has three fully operational rockets — the Polar Satellite Launch Vehicle (PSLV), and the GSLV-Mk II with a carrying capacity of 2.5 tonne and GSLV-MkIII with a payload capacity of four tonne.
