Hostile Environments and Cold War Machines
This chapter explores the place of satellite technology in the ionosphere’s transformation from natural order to hostile environment. It begins by examining geographic conceptions of hostile environments, their origins in World War II, their development in the early Cold War, and their extension in the late 1950s to include the deep oceans and outer space. It positions the DRTE satellite project (S-27) as part of a broader practice of using the threatened failure of machines to define environmental hostility. In addressing the problem of electronic failure in satellites, DRTE’s engineers drew on a military philosophy of hyper-reliability, generated by widespread concerns about the technological effects of punishing environments, and directed that philosophy towards the problem of reliably generating "topside" ionograms from space. S-27 formed a hinge between DRTE’s decade-long attempts to catalog a distinctive natural order and its eventual use of satellites to bypass it and secure Northern communications.
