There was abnormal operation of a SA-10 camera. Due to a camera malfunction, the satellite failed to take all of the images it had been programmed to produce.<ref name="Zarya">{{cite web|url=http://www.zarya.info/Diaries/Zenit/Zenit-2.php |title=Zenit Satellites - Zenit-2 variant|first=Robert|last=Christie|work=Zarya.info|access-date=3 January 2014}}</ref>
