ExoMars is the first mission in ESA's Aurora Exploration Programme. ExoMars will pursue important science and technology objectives aimed at extending Europe's capabilities in planetary exploration. ExoMars will deploy a Rover carrying a suite of instruments dedicated to exobiology and geology research. The Rover will travel several kilometres searching for traces of past and present signs of life, collecting and analysing samples from within surface rocks and from the subsurface, down to a depth of 2 metres. The planetary protection policy of the Committee on Space Research (COSPAR) and the particular sensitivity of the life detection investigations establish stringent contamination control constraints for the ExoMars mission. Particulate, molecular and bioburden contamination control beyond the level of standard spacecraft is required for the flight system as well as for the assembly, test, and launch environment.

In the frame of the space food production research activities conducted in the Thales Alenia Space Italia (TAS-I) Advanced Life Support Research and Development laboratory (RecycLAB, [6]), and with the contribution of a degree thesis developed in collaboration with the Politecnico of Torino, a rack-like facility for ground research on Life Support Systems based on Plants has been designed, developed, integrated, verified and tested in TAS-I. The new facility, called EDEN EPISODE 2, is a significant evolution of a previous TAS-I project (EDEN EPISODE 1) and takes benefit from other lower size TAS-I demonstrators (CUBE). It aims at realizing a completely closed and controlled environment for crop production, while a mobile lighting panel allows to maximize the delivered light in each phase of the plant life cycle. Hydroponic and aeroponic techniques have been implemented in the project for nutrient delivery to the plant roots.

The Atmospheric Revitalization System (ARS) provides carbon dioxide removal, trace contaminant control, and gas constituent analysis. In this field, the interest of RecycLAB [5], the TAS-I Advanced Live Support Research & Development laboratory is directed to trace gas contaminants removal and monitoring. During manned space mission, the decontamination of cabin or rack air after contingency events such as fire or pyrolysis is a priority for the crew safety. In this paper, basic zeolites, obtained by impregnation of common zeolites with a basic oxide, are used to remove acid gas contaminants from air stream. A multi-functional system, able to accommodate reactors of different shape, characteristics and set-up, is used at this purpose. This breadboard, called ZEUS (Zeolites for an Environmental-control Unit in Space), is made of AISI 316L stainless steel and consists of a closed loop, in which the inner volume is completely isolated from the external environment.

In the frame of the multi-disciplinary programme MoMa-COUNT [2], multi-functional protections for human space exploration are being investigated, paying particular attention to flexible materials, selected also for their single excellent structural, thermal and other environmental performances. These flexible materials in general have poorly known space radiation properties, whose lack of characterisation propagates the uncertainty about the shielding efficiency against the radiation environment on the whole spacecraft protection means. The consequent evaluation of their shielding efficiency, as well as of that of the overall shields, is based on flight experiments performed in Low Earth Orbit (LEO), onboard the International Space Station (ISS) and the re-entry capsule Foton. In parallel, supporting dedicated ground experiments in accelerators, as well as Monte Carlo simulations, are performed.

In the second half of the 2004, Thales Alenia Space - Italia started an Advanced Live Support Research & Development program denominated Recyclab, on own funding. The main objectives of the Recyclab program are: To determine the actual development needs and possibilities in the international scenario in the Advanced Life Support field To develop new technologies for the regeneration of the main resources in exploration missions (water, air, waste) To test the technologies developed in closed loop in an integrated system.

Crews of future exploration missions will be exposed for long time to a unique powerful mix of cosmic radiation. Starting from REMSIM study for ESA, we are focusing on short and long term shielding experiments aboard ISS (ESCHILO, ALTCRISS, SOFOCLE) by comparing the materials used in inflatable structures with the typical rigid materials used in current spacecraft, and optimizing and validating the radiation shielding solutions in LEO. To assess shielding strategies, tests in flight are always supported by calculations and laboratory experiments. The paper reports descriptions and available results of the above experiments.
