A 2010 technical report by the US Defense Threat Reduction Agency titled " Collateral Damage to Satellites from an EMP Attack ” lists Alouette 1 among the satellites damaged by residual radiation from the July 9 , 1962 Starfish Prime high-altitude nuclear test conducted by the United States . Another article , titled " Anthropogenic Space Weather " , indicates Alouette 1 sustained no significant adverse effects from the Starfish radiation , most likely due to a very conservative power supply design that allowed for a 40 % degradation of solar cell performance . '' Alouette '' s mission lasted for 10 years before the satellite was deliberately switched off on 30 September 1972 . The satellite remains in orbit ; in 1966 it was estimated that '' Alouette 1 '' would remain in orbit for 1000 years
