Explorer 5 was a United States satellite with a mass of 15.7 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 II rocket on March 23, 1960 from Cape Canaveral Air Force Station Launch Complex 26 , but failed when the rocket's first stage collided with its second stage after separation, causing the upper stage firing angle to be off.
