Radiation from Starfish Prime impacted the hardware and transistors of Telstar.
The first telecommunications satellite, Telstar, developed by AT&T, was launched just one day after the Starfish Prime test.
AT&T’s Telstar satellite, launched on July 10, 1962, was among those destroyed by radiation from Starfish Prime.
Telstar transmitted the first live transatlantic television pictures on July 23, 1962, before succumbing to radiation in November 1962.
Telstar developed TVAC3, a compact cube-shaped thermal vacuum chamber with external dimensions W1.25 m x H1.97 m x D0.818 m.
Telstar designed TVAC3 specifically to test CubeSat satellites and small satellite components.
