AB: ESPERIA is an equatorial magnetic, plasma and particle mission planned with a LEO small satellite for monitoring perturbations in the topside ionosphere and for defining the near-Earth magnetic environment. The project aims at reconcile these phenomena with Sun and Earth activities. So, in principle, Earth natural disasters, as earthquakes, the impact of anthropogenic electromagnetic radiation on the near-Earth space, atmospheric electromagnetic emissions during thunderstorm activity, and effects of sun and cosmic rays on the geomagnetic cavity can be studied by this mission. The ESPERIA Phase A Study, which has been realized for the Italian Space Agency (ASI), is mainly concerned with detecting seismic related signals from the Earth's surface. In particular, electromagnetic emissions related to the strong earthquake and possibly caused by stress changes in the Earth's crust, are a main scientific objective of this mission. ESPERIA includes a modular multi-instrument science payload constituted by a Magnetic Field Analyzer (two flux-gate and search-coil vector magnetometers), an Electric Field Analyzer (a constellation of ten Electric Probes), a Particle Detector, and an Ionospheric Plasma Analyzer (Langmuir Probe and Retarding Potential Analyzer). Most of these instruments are of large use in near-Earth Space investigations, therefore ESPERIA, with some relatively small changes and/or augmentation of its Payload, can easily be adapted for studying most of the applications mentioned above. So ESPERIA can also be seen as an equatorial coordinated and simultaneous complement to polar missions like SWARM, or "Living with a Star" NASA Program, etc. Two ESPERIA instruments (a particle detector and a search-coil magnetometer, included in the ARINA and LAZIO-SIRAD experiments) have been realized and will be tested in space. ARINA, which launch is scheduled for mid-2005 on board the RESURS DK-1 Russian LEO satellite, will perform particle measurements on a polar orbit. LAZIO-SIRAD will be installed on board the ISS next April 2005 to carry out magnetic and particle measurements.
