Space Exploration Roadmap has the ambitious goal of expanding the human presence into the Solar System including particularly the surface exploration of Mars and the Moon. Future space exploration programs aim a better understanding of (1) the origin and geological history of celestial bodies as well as their magnetization histories with related shielding effects, (2) exploration of extra-terrestrial volatile and water resources which can be used during future missions and (3) investigation of elemental enrichment processes and related formation of extra-terrestrial resources and ore deposits. However, recent multi-instrument suites do not provide devices to measure magnetic susceptibilities, which represent an important tool in the context of the previously described exploration aims.
NEWTON sensor is a key element to provide a detailed characterization of rock composition at future landing suites and surrounding areas by e.g. rover or robotic mapping. In particular, the potential regional magnetic shielding, due to a remanent magnetic rock behaviour, must be estimated with respect to possible past life formation as well as future habitability. Furthermore, such local to regional mineralogical and geophysical rock characterization will be important to detect and consider the potential of extra-terrestrial raw materials and ore deposits.
NEWTON device is at the forefront of technological innovation, given that, as far as NEWTON consortium knows, none of the current commercial or state of the art devices, although they could have better performances in terms of resolution, sensitivity or frequency range, are oriented to a compact hand-held device for the measurement of the complex magnetic susceptibility without the need of sample preparation in a space environment. Furthermore, NEWTON project provides potential opportunities for spin-in/spin-out effects between space and non-space field technologies. With this regard, NEWTON novel technologies can be applied in different fields being the geophysical engineering one of the most relevant. High resolution mapping of distinct magnetic properties might provide a characterization of most distinct natural rocks and their complex three-dimensional geological structure which allows a better in-situ interpretation with the consequent time and cost savings.
