Inadequate Cryo pressure caused GSLV-F10/EOS-03 Mission Failure; FAC Concludes
Updated: Mar 26, 2022
The Failure Analysis Committee submits conclusions of ISRO's GSLV MkII mid-flight Rapid Unscheduled Disassembly due to upper stage inadequate LH2 tank pressure.
INDIA; On August 12, 2021, ISRO's GSLV-F10 rocket lifted-off at T-0 at 0013 UTC, into the Geo Synchronous Orbit trajectory, on board with agency's Earth Observation Satellite (EOS-03) from Satish Dhawan Space Center, Sriharikota.
In the flight, the performance of the first stage (GS1), the strap-on stages (L40) and the second stage (GS2) were nominal. Per contra, the onboard computer aborted the mission at 307 seconds into the flight, leading to mission failure
Post flight failure: The FAC has thoroughly reviewed the flight data and Simulated the GSLV-F10 flight scenario and validate the findings of the Committee. Subsequently, the respective teams have completed the simulations & ground tests and presented the results, based on which FAC has completed its deliberations and presented its findings and conclusion on March 24, 2022.
The FAC concluded that the lower LH2 (liquid Hy
