In Michael Crichton’s “The Andromeda Strain,” the satellite crashes near the fictional town of Piedmont. The 1969 novel begins with a U.S. satellite returning from space and landing in the American Southwest. When investigators examine the nearby area, they discover that almost everyone in Piedmont has died suddenly, creating the mystery at the center of the story.
Piedmont is not simply a backdrop: its dead residents provide the first evidence that the satellite has brought back an unfamiliar extraterrestrial microorganism. The organism, later called the Andromeda Strain, behaves unlike an ordinary terrestrial pathogen and leads the government to activate a team of scientists.
The novel’s Piedmont is generally associated with Arizona, while film and television adaptations have used different locations, including New Mexico and Utah. That variation can cause confusion, but the town’s name remains Piedmont. Crichton published the techno-thriller in 1969, combining medical detail, military procedure, and speculative science in a documentary-like style.
