Early Rockets

America’s first scientific satellite, the Explorer I, carried the radiation detection experiment designed by Dr. James Van Allen and discovered the Van Allen Radiation Belt. It was launched aboard a modified redstone rocket known as the Jupiter C, developed by Dr. von Braun’s rocket team at Redstone Arsenal in Huntsville, Alabama. The satellite launched on January 31, 1958, just 3 months after the the von Braun team received the go-ahead.
