ISRO Team Says Cable Rupture Caused Rocket Failure

摘要

A preliminary analysis of data from the failed launch of India's Geostationary Satellite Launch Vehicle (GSLV) Dec. 25 has led an expert team to conclude that the primary cause of the mishap was the "untimely and inadvertent snapping" of a group of 10 connectors located at the bottom of the rocket's Russian-supplied upper stage.rnThe Indian Space Research Organisation (ISRO) said in a Dec. 31 statement that the vehicle's performance was normal up to 47.5 seconds after liftoff. It then began to stray from its planned orientation angle, which resulted in higher structural loads than the vehicle was designed to handle.
