This research investigates a prototype tool to assess habitability indicators in diverse environments, highlighting its potential for robotic exploration.
One key objective of astrobiology is to investigate and discover if other planetary bodies are habitable. The determination of whether an environment is habitable to known life requires measuring liquid water, CHNOPS elements, other nutrients, and energy supplies. Here we investigate the potential for a single instrument capable of sampling these key indicators: a ’Total Habitability Instrument’. The proposed instrument would be capable of deployment in diverse environments and provide an integrated set of measurements that together allow for the assessment of the habitability of a given environment. We explore existing and potential technological developments that would enable the construction of such an instrument, with a focus on soft systems, that are inspired from nature in their design, and microfluidics. This paper considers a multidisciplinary approach to the design and sensing requirements of a total habitability instrument that would be capable of gathering and processing samples and be deployable by both robotic and human explorers on all planetary bodies, allowing for the mapping of habitability over large areas of our Solar System and beyond.
