Solar System Surface Technosignatures: Searching for Signs of Artificial Design on Extraterrestrial Terrain

Key points

• Artificial radio emissions have historically been a major focus of technosignature searches.1
• On geologically inactive bodies such as the Moon and Mars, artificial traces and patterns could potentially remain visible for hundreds of millions of years.1
• We discuss two recent developments that make this search timely: high-resolution imaging datasets, such as those produced by the HiRISE camera on the Mars Reconnaissance Orbiter (MRO), and ML-based anomaly-detection methods.1
• Finally, we list two possible approaches to developing a model capable of searching for these surface technosignatures: a supervised and an unsupervised one.1

  Here, we apply an anthropological lens to expand this scope to surface technosignatures: non-random, intentional patterning on planetary terrain, similar to long-lasting human-made landscapes and monuments on Earth.

  Artificial radio emissions have historically been a major focus of technosignature searches.
