Spacecraft that survive their nominal mission lifetime are generally proposed for a mission extension to maximize their return on investment. Currently, the remaining lifetime estimates to support mission extension decisions are largely based on cons

Recent numerical studies indicate that the low Earth orbit (LEO) debris environment has reached a point such that even if no further space launches were conducted, the Earth satellite population would remain relatively constant for only the next 50 y

During recent years, the state-of-the-art risk assessment of the threat posed to spacecraft by micrometeoroids and space debris has been expanded to the analysis of failure modes of internal spacecraft components. This method can now be used to perfo

Through the use of the Geant4 Radiation Analysis for Space (GRAS) Monte Carlo tool, we present new results on the impact of different space habitat shell compositions on on-board electronics Soft Error Rate (SER) induced by Galactic Cosmic Rays (GCR)

Through the use of experimental data and Monte Carlo simulations we investigate the shielding properties of spacecraft-shell compositions exposed to 1 GeV/nucleon 56Fe ions, representative of the worst part of the Galactic Cosmic Ray (GCR) spectrum.

The purpose of the present paper is to introduce a new integral model capable to describe the evolution of the debris clouds originated after normal-impacts of orbital debris over a Whipple shield. This work had been developed at Alenia Spazio in the
