A Satellite Heard “Play Doom” and Launched the Game in Orbit
An amateur-radio team in Oslo used a spoken command to make ESA’s experimental OPS-SAT PRETTY satellite launch Doom. The team’s account describes two successful passes on July 27, 2026, combining onboard audio processing, speech recognition and a command matcher.
The actual story.
Doom has another unusual home: a satellite that launched the game after hearing a command from Earth. Tanagra Space’s account dates the experiment to July 27, 2026, rather than a new event this week.
An amateur-radio team in Oslo transmitted to ESA’s OPS-SAT PRETTY spacecraft. The satellite recovered audio from the radio signal, transcribed it with an onboard speech-to-text model and checked the result for a command. When it found a match, it launched Doom and sent back a postcard image.
The team reports two successful passes that day: a looping synthesized voice in the morning and a live operator speaking into a microphone in the evening. It describes the experiment as the first autonomous satellite response to a plain-language voice command, a priority claim attributed to the project.
The demonstration used a specific command detector, not an unrestricted conversational assistant. Its appeal goes beyond the familiar joke of putting Doom on unexpected hardware: it combined radio reception, interpretation and an onboard action in one experiment.
This experiment showed that a satellite could recognize a specific spoken command and launch a program onboard. As satellites process more information in space, they could identify events such as wildfires and prioritize important images for transmission, instead of waiting for data to be analyzed on Earth.
Receipts, not rumors.
