Parade of progress

This representation of the Telstar 1 satellite -- others would follow in later years, up through Telstar 18, launched in 2008 -- was created for use at the Parade of Progress show in Cleveland, likely within a couple years of that first transmission. (It's not clear from the information available whether this was a painting, a diorama with a scale model, or some other kind of presentation.)

About three feet in diameter and weighing 170 pounds, Telstar had two power sources for its electronics equipment. The primary source was a solar array with 3,600 solar cells, and backup power was available from a battery system. The satellite was spin-stabilized, according to NASA, to maintain its orientation.
