Item Analysis of Ammonia Moderate Leakage in Columbus(45th International Conference on Environmental Systems, 2015-07-12) Parodi, Paola; Locantore, Ilaria; Palo, Savino De; Szigetvari, Zoltan; Hinderer, StephanThis paper describes the analysis prepared to define the inputs for a timely detection and response to an ammonia moderate leakage from ISS Thermal Control System (TCS) into the Columbus module TCS water loop. Ammonia leakage is currently classified into three levels, with two extremes: the micro-leak, detectable generally via sample/strip analysis methods, the rupture, with a visible (FDIR reaction) flow of ammonia into the water loop, and the intermediate moderate leakage, visible via telemetry. At the time being, neither a moderate leak Flight Rule (FR) nor a dedicated malfunction procedure is available in Columbus’ books, therefore no guidance is provided to the flight team if a leak of that size develops. The advantage of implementing a moderate leakage response is that it covers the ‘gray zone’ between micro-leak and rupture, thus avoiding every leakage greater than the micro-leak to be treated as rupture, with the risk of over-reacting and stopping the activities inside the module when it is not the case.Item Biocontamination Integrated Control of Wet Systems for Space Exploration (BIOWYSE)(48th International Conference on Environmental Systems, 2018-07-08) Guarnieri, Vincenzo; Detsis, Emmanuel; Locantore, Ilaria; Lobascio, Cesare; Boscheri, Giorgio; Marchitelli, Giovanni; Simons, Richard; Pagan, JenniferControl of microbiological contamination within spacecraft is of huge importance for long-duration manned space missions: such systems must guarantee crew well-being, health, and subsistence. The development of materials and methods to prevent, monitor, and mitigate environmental microbial contamination and its harmful effects are thus required. Considering the application of such systems to spacecraft, possible solutions must be safe, automated, lightweight, reliable, efficient, and require minimal energy, consumables, maintenance, etc. The “Biocontamination Integrated Control of Wet Systems for Space Exploration” (BIOWYSE) project focuses on the development and demonstration of a compact, integrated, and automated solution (hardware & software) to biocontamination control. The BIOWYSE system is designed to prevent, monitor, and mitigate the risk of microbiological contamination in water systems and humid surfaces onboard ISS and in future human space exploration missions. Automation and synergy of these processes lead to reduction in crew time, decreased energy requirements, procedure simplification, and additional safety measures. Prevention and real-time monitoring, together with an appropriate control system, can reduce the decontamination effort requirement and radically improve efficiency. The BIOWYSE system and its subsystems, modules, and operational modes are described in this paper.Item Biocontamination Integrated Control of Wet Systems for Space Exploration (BIOWYSE) – Testing campaign results(49th International Conference on Environmental Systems, 2019-07-07) Locantore, Ilaria; Boscheri, Giorgio; Guarnieri, Vincenzo; Marchitelli, Giovanni; Saverino, Antonio; Lobascio, CesareControl of microbiological contamination within spacecraft is of huge importance for long-duration manned space missions: such systems must guarantee crew well-being, health, and subsistence.

The Horizon2020 EDEN ISS project aims at development and demonstration of higher plant cultivation technologies, suitable for near term deployment on the International Space Station (ISS) and from a long-term perspective, within Moon and Mars habitats. The EDEN ISS consortium, as part of the performed activities, has designed a plant cultivation system to have form, fit and function of an European Drawer Rack 2 (EDR II) payload, with a modularity that would allow its incremental installation in the ISS homonimous rack, occupying from one-quarter rack to the full system. The construction phase is started, and the developed system will be tested in a laboratory environment as well as at the highly-isolated German Antarctic Neumayer Station III, in a container-sized test facility to provide realistic mass flow relationships and interaction with a crewed environment. This paper describes the goals and system general design status of EDEN ISS ISPR plant growth facility.Item Use of adsorbent photocatalytic materials for air revitalization in space closed environment(44th International Conference on Environmental Systems, 2014-07-13) Grizzaffi, Lucia; Locantore, Ilaria; Pandi, Arianna; Boscheri, Giorgio; Lamantea, Matteo; Onida, Barbara; Loiacono, EleonoraThe Air Revitalization is one of the main objectives of the Life Support & Biotechnologies research of RecycLAB TASI Engineering Technological Area. A “small- scale” module mock up, called Athena, has been recently designed and realized for allowing the possibility to simulate a contaminated confined environment, as a crew cabin is, and test the efficiency of adsorbent materials within reactors of different shape specifically conceived. This paper deals with the synthesis, the characterization and the testing of Titania-containing porous silica (TiO2–SiO2) as trace gas traps. In particular, two post- synthesis methods of TiO2 incorporation inside mesoporous SBA-15 silica support have been selected. The obtained products have been characterized and compared from the chemical- physical and morphological points of view (by XRD, IR and UV-VIS spectroscopy, N2 adsorption, FESEM-EDS and DLS). The test campaign focused on the evaluation of the combined effect of photocatalytic and adsorbent properties for ethanol and dichloromethane removal in vapour phase by means of Athena. The VOCs concentration decrease over time was monitored by means of a FT-IR spectrometer for kinetic analysis, equipped with a temperature controlled gas cell connected to the mock up in a closed loop system.
