Equipment used for spaceflight is always very sophisticated technically, due to the complexity of the systems involved, the fact that they have to be deployed without much of a safety margin and the relative scarcity of options for real-time adjustments. Although rocket technology has been continuously and very successfully developed over the years, the aforementioned aspects imply that 'absolute certainty' is a pipe dream. This fact reared its head once again during the launch of two Galileo satellites on 22 August 2014. read more
