GSLV-F06 打ち上げ失敗

インドのGSLVロケットが打ち上げ失敗したようです。今回の打ち上げには通信衛星GSAT-5Pが搭載されていた模様。


リフトオフから40数秒あたりで急激に姿勢を失い、ペイロード部とみられるものが脱落して爆発（指令破壊？）。これはショックですよね…。

The liquid-fueled L40 boosters are each powered by a single engine producing about 170,000 pounds of thrust. The engines burn hydrazine and their nozzles pivot to steer the rocket during the first two-and-a-half minutes of flight.

Something prevented computer steering commands from reaching the engine gimbal system, Radhakrishnan said in a press conference several hours after the rocket accident.

"What has caused this interruption at 47 seconds has to be studied in detail," Radhakrishnan said. "We hope to get an assessment of exactly what occurred."
