A LM-3B was launched from Xichang Satellite Launch Center at 3: 01 on Feb. 15 with the Intelsat 708 but began to experience an anomaly in attitude about 2 sec. later. It touched down with its nose at about T+22s and exploded violently. The failure is under intensified investigation. The analysis of the telemetered data has shown that the crash was caused by a change in the inertial reference, which is to be confirmed through further analysis and demonstration. 展开更多
