MISSION BEYOND: THE NUTRISS EXPERIMENT ON BOARD THE INTERNATIONAL SPACE STATION

摘要

Energy balance maintenance is a crucial point to preserve astronaut's wellness and quality of life in space. Human spaceflight and experimental bed-rest highlights the relevance of nutritional intervention to counteract the microgravity (micro-g) detrimental effect on skeletal muscle mass and metabolism. NutrISS (Nutrition monitoring for the International Space Station) is an Italian Space Agency (ASI) biomedical experiment investigating patho-physiology of changes in body composition during long-term spaceflight. It will be executed on the ISS (July-December 2019), during the Beyond mission of Luca Parmitano, sponsored by the European Space Agency. The goal of this proof-of-concept is to monitor the body composition of astronauts and, if needed, to provide nutritional advices during the mission. The payloads selected for the mission "BEYOND" are funded and coordinated by ASI, resulting from a public call open to the industrial and scientific research communities. ASI, in the frame of its national mission of promoting and fostering the culture of space across the Country, provides access to the ISS as a laboratory in space to the Italian research community. The utilization support services are provided thanks to a contract awarded by ASI to ARGOTEC/Telespazio (UTISS Team). This team supports safety evaluation and payload manifesting and qualification process leading towards a safe and efficient delivery, utilization, integration on board the ISS and recovery of the payload, allowing scientists to access and retrieve experimental data and instruments after they return to Earth. For the NutrISS experiment, the Italian astronaut Luca Parmitano has been subjected to Baseline Data collections before leaving for his seven-months mission. Body composition, anthropometric evaluation and energy and metabolic assessment has been performed by the scientific team (Università degli Studi di Trieste). Body composition has been assessed with a COTS Bio-Impedance Analyzer (BIA) de
