The move follows a quiet visit by National Security Advisor Ajit Kumar Doval to the Vikram Sarabhai Space Centre in Thiruvananthapuram.
A Spanish startup, Orbital Paradigm, claims its payload, KID, survived the failed PSLV-C62 mission and transmitted data, despite ISRO's silence on the matter. The mission, carrying 16 satellites, failed due to issues in the rocket's third stage.
Based on the broadcast visuals, a rocket expert said the failure appeared similar to the anomaly seen during the PSLV-C61 mission.
These upcoming launches carry added significance in light of setbacks suffered in recent years.
ISRO is preparing for the PSLV-C62 mission launch on January 12 from Sriharikota, carrying the EOS-N1 satellite and multiple other payloads.
ISRO's PSLV-C62 successfully launched an earth observation satellite along with 14 other commercial payloads from Sriharikota, marking the first launch of the year.
'A solid motor, once ignited, burns until the propellant is exhausted. It cannot simply stop mid-burn,' said a retired senior ISRO official. 'That is what makes this failure puzzling.' Venkatachari Jagannathan reports on the latest PSLV failure.
ISRO has announced plans for seven launch missions by March, including the first uncrewed mission for the Gaganyaan project and demonstrations of new satellite technologies.
