High Energy Rapid Modular Ensemble of Satellites, Scientific Pathfinder (HERMES-SP) is a mission concept based on a constellation of nano-satellites in low Earth orbit (LEO), hosting new miniaturized detectors to probe the X-ray temporal emission of bright high-energy transients such as Gamma-Ray Bursts (GRB) and the electromagnetic counterparts of Gravitational Wave Events (GWE). HERMES-SP main goal is to design and implement the first GRBs localisation experiment through a distributed space architecture realized by a 3 +3 CubeSat federation
(designed and implemented by Politecnico di Milano, through a collaboration led by Istituto Nazionale di Astrofisica - INAF), each equipped with a novel detector to gain a wide deep space coverage and demonstrate capabilities in precisely localising the GRB event in space. The HERMES-SP project exploits synergies with an ongoing project funded by the Agenzia Spaziale Italiana (ASI). Distribution in space and event detection are the fundamental ingredient to start building up the whole scientific experiment. HERMES-SP is aiming at demonstrating detection and localisation of high-energy transients feasibility with disruptive technologies and limited effort. The project is coordinated by Istituto Nazionale di Astrofisica and involves elevent partners: Univerza v Novi Gorici, Politecnico di Milano, SkyLabs vesoljske tehnologije d.o.o. (SkyLabs), Università degli Studi di Cagliari, DEIMOS Space Sociedad Limitada Unipersonal, Aalta Lab-razvoj zmogljive programske opreme d.o.o., Fondazione Politecnico di Milano, Eberhard Karls Universität Tübingen, Eötvös Loránd Tudományegyetem and C3S Electronics Development LLC
. HERMES-SP is funded by European Union under the programme Horizon 2020
. The project started in November 2018 and will end in October 2021.
