“…These passive witness plate experiments were finely tuned to measure specific individual processes over a fixed amount of time in manner that supplemented other types of observations. Witness plates have also been used to assess contamination and explore scientific questions related to planetary science beyond the Moon-the Genesis mission (Nordholt et al, 2003) collected samples of the solar wind (SW) is a manner similar to the Apollo Solar Wind Composition Experiment and the Perseverance Rover on Mars utilized numerous calibration targets and witness tube assemblies over its duration (Fries et al, 2022;Kinch et al, 2020;Moeller et al, 2021).…”

Future exploration efforts of the Moon, Mars, and other bodies are poised to focus heavily on persistent and sustainable survey and research efforts, especially given the recent interest in a long‐term sustainable human presence at the Moon. Key to these efforts understands a number of important processes on the lunar surface for both scientific and operational purposes. We discuss the potential value of in situ artificial substrate witness plates, powerful tools that can supplement familiar remote sensing and sample acquisition techniques and provide a sustainable way of monitoring processes in key locations on planetary surfaces while maintaining a low environmental footprint. These tools, which we call Biscuits, can use customized materials as wide ranging as zircon‐based spray coatings to metals potentially useable for surface structures, to target specific processes/questions as part of a small, passive witness plate that can be flexibly placed with respect to location and total time duration. We examine and discuss unique case studies to show how processes such as water presence/transport, presence and contamination of biologically relevant molecules, solar activity related effects, and other processes can be measured using Biscuits. Biscuits can yield key location sensitive, time integrated measurements on these processes to inform scientific understanding of the Moon and enable operational goals in lunar exploration. While we specifically demonstrate this on a simulated traverse and for selected examples, we stress all groups interested in planetary surfaces should consider these adaptable, low footprint, and highly informative tools for future exploration.

“…For 28 months, the Genesis spacecraft collected solar wind (SW) in ultrapure target materials [4] and returned them to Earth in September, 2004. In order to enhance the collection of oxygen from the solar wind, the spacecraft included an electrostatic mirror, the SW concentrator [5], which increased the fluence of oxygen by a factor of 20 over the bulk solar wind. With this enhancement, the average SW oxygen implanted in the samples was predicted to be 3 Â 10 14 cm À2 with a mean implantation depth of $ 100 nm.…”
