Isro encountered anomaly in satellite trajectory during third stage flight

According to Chris Bergin of NasaSpaceFlight.com (NSF), the mission suffered a "major failure" during the third stage flight.

"2-3 sep looked good, but the third stage started to roll shortly after ignition, and then it progressively worsened," he said. "Then the telemetry lines diverged. This will soon be classed as a loss of mission."
