  The impacts of Cosmic Rays on the detectors are a key problem for space-based
missions. We are studying the effects of such interactions on arrays of Kinetic
Inductance Detectors (KID), in order to adapt this technology for use on board
of satellites. Before proposing a new technology such as the Kinetic Inductance
Detectors for a space-based mission, the problem of the Cosmic Rays that hit
the detectors during in-flight operation has to be studied in detail. We
present here several tests carried out with KID exposed to radioactive sources,
which we use to reproduce the physical interactions induced by primary Cosmic
Rays, and we report the results obtained adopting different solutions in terms
of substrate materials and array geometries. We conclude by outlining the main
guidelines to follow for fabricating KID for space-based applications.
