Explorer 5 was a United States satellite with a mass of 17.24 kg. It was the last of the original series of Explorers built, designed, and operated by the Jet Propulsion Laboratory.[1]
It launched atop a Juno I rocket on August 24, 1958 from Cape Canaveral Air Force Station Launch Complex 5 , but failed when the rocket's first stage collided with its second stage after separation, causing the upper stage firing angle to be off.[2]
Explorer 5 had been intended to be one of two satellites used to gather data for Project Argus.
