Abstract

ESPERIA is an equatorial mission planned with a LEO small-satellite and a multi-instrument payload. The project has been ideally conceived to define the near-Earth electromagnetic, plasma, and particle environment, both in steady-state and perturbed-state conditions. In recent times has been observed that either Earth’s interior processes or near-Earth space phenomena have a privileged and sensitive zone of investigation constituted by the ionosphere-magnetosphere transition region, at altitudes ranging around 5001000 km. In fact, sun and cosmic rays as well as, seismic, anthropogenic and thunderstorm activities, influence the structure and dynamics of the zone. These external and internal contributions play an important role in defining the particle and electromagnetic field character of the region, both in steady-state and perturbed-state conditions. So, a suitable monitoring of the topside ionosphere may give an help in studying many important physical phenomena as pre-earthquake and anthropogenic electromagnetic emissions, solar wind and flares, as well as in mapping the geomagnetic field. The ESPERIA Phase A Study has been performed by an International Consortium lead by the University Roma Tre, within the Earth observation program for small scientific missions of the Italian Space Agency (ASI). The scientific objectives of the study are to plan an EM, plasma, and particle mission concerned with detecting tectonic, anthropogenic, and preseismic related EM signals. The primary aim of the mission is to study ionospheric and magnetospheric effects caused by seismicity to develop methods for the evaluation of seismic risk (providing for disaster assessment) and give contribution in earthquake forecasting studies. A secondary objective is the study of electromagnetic emissions of anthropogenic origin (power line harmonic radiation, VLF and HF transmitters) and their influence in the ionosphere and magnetosphere. To achieve the objectives with maximum reliability, ESPERIA is based with strong emphasis on coordinated, simultaneous, and continuous ground-based and space observations, as well as on mutual data comparison with other missions of similar quality. On board the satellite ULFHF electromagnetic fields, fluxes of charged particle (200 keVGeV), and ionospheric plasma temperature and density will be detected. Ground-based measurements of mechanical (tilt and strain) and electromagnetic fields will be carried out in several test areas of the Earth’s surface.
