January 7, 2018 SpaceX launched USA’s mysterious satellite called Zuma with falcon 9 rocket. Unfortunately after the launch the satellite worth $3.5 billion went missing and there were speculations that spacex’s rocket might have been the cause of this mishap.
But Wall Street Journal today reported that this loss was due to engineering and testing errors made by aerospace and defense firm Northrop Grumman Corporation, according to recently concluded investigation. The payload adapter modified by Northrop Grumman failed to operate properly during deployment, causing the $3.5 billion satellite to stay attached to the second stage Falcon 9 rocket during its descent stage. After a brief period in space, the zuma satellite re-entered Earth’s atmosphere, likely splashing down somewhere in the Indian Ocean.
