The SPace and AStroparticle Group SPAS is involved in two projects of Astroparticle Physics with a common goal: the study of Ultra High Energy Cosmic Rays reaching the Earth with energies higher than 10¹⁷eV from the Earth surface with the Pierre Auger project and from the space with the EUSO program.

High Energy Astrophysics includes among other topics the study of particles, orginated in the cosmos long time ago, reaching the Earth.
