### Overview

A new proposal calls for **technosignature searches to expand beyond radio astronomy** and examine the surfaces of nearby worlds for physical evidence of past intelligent activity. The paper, *Solar System Surface Technosignatures: Searching for Signs of Artificial Design on Extraterrestrial Terrain*, was released October 20, 2026, by Ana Henrique, Sofia Sheikh and Benjamin Fields. A related proposal was presented at the Europlanet Science Congress in September by Ana Henrique Salvan and Caleb Strom.

The researchers’ central question is whether an advanced civilization that existed millions—or even hundreds of millions—of years ago could have left recognizable traces on Mars or the Moon. Possible evidence could include **large structures, roads, excavations, geometric formations or other deliberate alterations** to the terrain. The study does not claim that such remains have been found. Rather, it argues that existing planetary imagery could be systematically reviewed for patterns that merit closer scientific investigation.

### Searching Existing Planetary Archives

Mars and the Moon are considered useful targets because both preserve extensive ancient terrain and lack many of the erosional processes that continually reshape Earth. The Moon, in particular, retains impact craters and surface features formed billions of years ago. On Earth, aerial and orbital surveys have revealed roads, agricultural terraces and buried settlements long after their builders disappeared. Comparable features on another world might survive even if the original structures collapsed, became buried or were damaged by impacts.

NASA’s **Mars Reconnaissance Orbiter**, operating at Mars since 2006, has collected high-resolution imagery with its HiRISE camera. Under favorable conditions, the instrument can resolve features approximately 25 to 32 centimeters across per pixel. Researchers propose using artificial-intelligence tools to examine these large archives more efficiently than would be possible through manual inspection alone. Any candidate feature would still require geological analysis, independent imagery and careful efforts to rule out natural explanations such as erosion, shadows, fractures or unusual deposits.

### Beyond Radio Technosignatures

The proposal reflects a broader shift in the search for extraterrestrial intelligence. Traditional technosignature research has often focused on **radio transmissions, optical pulses or other energy emissions**. Surface searches would add a different category: physical evidence of technology that might remain long after a civilization ceased communicating. The approach also connects with wider discussions about potentially habitable environments, including **super-Earths orbiting K-dwarf stars**. These relatively cool, long-lived stars are being studied as possible locations for planets that could retain stable conditions for extended periods, although habitability depends on many factors, including atmosphere, radiation and geological activity.

The material also addresses reports of unusual objects in Earth’s skies. Apparent extraordinary motion can result from **parallax, movement of a camera or observer, uncertain distance estimates and misidentified aircraft, balloons, satellites or atmospheric phenomena**. Without reliable information about an object’s range, size and sensor geometry, rapid acceleration or abrupt changes in direction can be misinterpreted. These explanations do not resolve every report, but they illustrate why calibrated data from multiple sensors is essential before drawing conclusions.

### Separating Evidence From Speculation

The discussion additionally summarizes claims attributed to Matthew Brown involving mind-controlled UFOs and alleged human breeding programs. Those ideas are **unverified speculation**, not established scientific findings, and no supporting evidence is provided in the material reviewed here. The same evidentiary standard applies to proposed structures on Mars or the Moon: unusual images would be a starting point for investigation, not proof of an ancient civilization. For now, the significance of the proposal lies in its testable method—using modern image-analysis tools to search systematically while treating natural explanations and uncertainty as central parts of the process.
