Enos

The chimp who orbited, obeyed, and was punished by his machine.

November 29, 1961 — Cape Canaveral smelled of kerosene and salt. Inside the Mercury-Atlas 5 capsule, a chimpanzee named Enos sat strapped to a couch, his pulse somewhere between fear and routine. He had done this hundreds of times in training — flip the lever when the light turns, wait for the tone, receive the banana pellet. That morning, there were no pellets.

He’d been trained by the U.S. Air Force and NASA — conditioned with shocks and rewards until obedience became reflex. He was the stand-in for John Glenn, a living rehearsal. When the Atlas rocket lit, the capsule shook, and Enos rose through cloud and ion flame into the indifference of orbit.

He completed one revolution, then another. The flight computer malfunctioned. Each time he performed a correct task, the system misfired and shocked him. He kept working anyway. The capsule’s temperature spiked. Controllers aborted the third orbit and brought him down through layers of friction and fire, splashing hard into the Atlantic.

Recovery crews found him dazed but alive, clinging to the seat as if it still held gravity. His report read: Mission successful, objectives achieved. The margin note: subject agitated.

He was retired to the Holloman base in New Mexico, where no one needed to measure his reflexes anymore. He lived another year. Then he vanished into paperwork and rumor.

The first American to orbit Earth was a chimp who was shocked for following instructions. He did everything right. The system just got it wrong.
