Between April 2021 and January 2024, the Ingenuity drone performed 72 flights in the Martian atmosphere. This technology demonstration paved the way for future exploration of Mars using Unmanned Aerial Vehicles (UAV). However, it is not yet clear which landforms and surface processes will benefit from this new technology.
This study therefore aims to further investigate the geomorphic features on Mars that will gain to be studied from a UAV perspective. To do so, a First Person View (FPV) drone is used to image Martian geomorphic features analogues at different ground sampling distance (GSD). Analysis of the images and comparison with current in-orbit capabilities on Mars are performed to determine the needed GSD and derive recommendations for future Mars rotorcraft missions. Analogues of ejecta blocks, gullies and patterned grounds were found and imaged within the Haughton impact crater on Devon island during the field campaign of the NASA Haughton-Mars Project (02/08/2024 to 14/08/2024).
The ejecta blocks and gullies appeared to be interesting targets for UAV studies on Mars. A GSD of 6 centimeters per pixels has been identified as an upper bound to properly observe the damage state of a boulder and distinguish its impact-related origin from other hypothesis (boulder slide remnant or glacier erratic). The gully characterization, and especially the identification of a wet origin can be performed with GSD lower than 2 centimeters per pixels. However, UAV studies of patterned grounds revealed no particular benefits since the needed GSD to identify their formation mechanism was low enough to be performed using rovers. The UAV perspective only enable the identification of smaller patterns than the one observed with satellite imagery. ...
