We averted a possible debacle: ISRO chairman
News
- ISRO recently recall its satelliteGSAT-11 midway between its reaching the French port and the launch.
Important facts
2. ISRO’s Chairman K. Sivan has recently justified the decision
3. Dr. Sivan said an apex committee of former chairmen and former space commission members collectively decided to bring GSAT-11 back to Bengaluru for a thorough check.
4. Reason for Recall
- GSAT-11 had the same set of power system configuration that RISAT-1 and GSAT-6A
- RISAT-1 died prematurely and GSAT-6A had lost communication contact soon after launch on March 29 because of suspected power system failure
- Checks also found that the provision or “margin” for the deployment of the solar panel was much smaller than was required. This would reduce the life of satellite
5. Although, ISRO had envisioned that GSAT-11 — its heaviest to date and most ambitious for digital communication — would be its last satellite to go outside India for a launch
6. But upgrading a GSLV-Mk2 engine take more time and bigger Mark 3 was also not available in time.
