ALTEA: anomalous long term effects on astronauts on board the international space station
No full textIn questo lavoro di tesi sarà riportato il lavoro portato avanti sull’esperimento ALTEA durante i miei anni di dottorato.
ALTEA (Anomalouos Long Term Effects on Astronauts) è un progetto finanziato dall’ASI, Agenzia Spaziale Italiana; è un programma multidisciplinare rivolto allo studio degli effetti funzionali della radiazione durante la permanenza umana nello spazio e contemporaneamente rivolto ad ottenere una misura della radiazione ambientale all’interno della Stazione Spaziale Internazionale (ISS). ALTEA è costituito da diversi esperimenti sia a terra che nello spazio.
Il mio coinvolgimento ha riguardato principalmente l’esperimento ALTEA-space di cui ho seguito personalmente i test hardware, le calibrazioni su fascio e l’analisi dei dati di volo.
Dopo una introduzione sull’ambiente spaziale e una breve descrizione dei principali effetti dell’esposizione a radiazione, riportate nel capitolo 1, nel capitolo 2 è presentato il programma ALTEA, con i suoi obiettivi scientifici e i differenti esperimenti che lo compongono. La facility ALTEA-space è descritta invece nel capitolo 3.
Nel 4 capitolo è riportata una semplice simulazione utilizzata per il calcolo del flusso di particelle atteso all’interno della ISS.
Nei capitoli successivi è per primo descritto tutto lo studio da me effettuato per verificare le performances e le caratteristiche del rivelatore ed in seguito vengono descritte le due sessioni di test eseguite all’acceleratore di particelle del GSI per testare e calibrare il modello di test (TM) e il modello di volo (FM) dell’apparato. Questo lavoro preliminare è stato completato con l’analisi dei dati acquisiti a terra dal modello di volo di ALTEA con tutti i sottosistemi accesi.
Dopo la consegna dell’hardware di ALTEA-space a NASA, ho contribuito alla configurazione ed installazione dell’ALTEA User Home Base (UHB) dove vengono ricevuti tutti i dati di volo e da dove sono effettuate le comunicazioni verso NASA a supporto delle operazioni di volo. Prima dell’inizio della missione ho partecipato alle simulazioni NASA volte a familiarizzare con le operazioni di volo.
ALTEA è stata finalmente portata a bordo della Stazione Spaziale Internazionale all’interno della missione Shuttle STS-121 il 4 Luglio 2006; nell’ultimo capitolo di questa tesi è descritto lo stato attuale delle operazioni di volo e sono presentati i risultati dell’analisi condotta sui primi dati raccolti sulla ISS. In questa tesi sono stati analizzati circa tre mesi di dati e i primi risultati includono tra gli altri lo studio del flusso di particelle, I differenti flussi rivelati dai sei rivelatori di particelle e un primo calcolo delle abbondanze nucleari relative.
Ho infine contribuito a realizzare e a testare gli strumenti software di preprocessamento e di analisi dei dati usati sia per i dati di calibrazione che per i dati di volo. Questi strumenti sono stati sviluppati utilizzando diversi linguaggi di programmazione (C, VC++, VB, IDL).In this thesis I summarized the work carried out on ALTEA experiment during my PhD years.
ALTEA (Anomalouos Long Term Effects on Astronauts) is a project funded by ASI, the Italian Space Agency; it is a multidisciplinary program devoted to investigate the functional effects of radiation during man permanences in space and concurrently to get a measure of radiation environment inside the International Space Station. It is constitued by several experiments both gorund-based and in space.
I was mainly involved in the ALTEA-space experiment and I followed the hardware functioning tests, the calibration and the analysis of flight data.
After an overview of space environment and a brief description of the main effects of radiation exposure, reported in the first chapter, the Altea program is presented with its scientific goals and the different experiments that it includes. In particular the ALTEA-space facility is described in the third chapter.
In the fourth chapter a simple simulation to calculate the expected particle flux inside the ISS will be presented.
In the following chapters, first of all the study I performed to verify the detector performances and characteristics is described, then the two session tests carried out at the GSI accelerator in order to test and calibrate the Flight Model and the Test Model of the device. This preliminary work was completed with the analysis of the files acquired on ground with all ALTEA Flight Model subsystems active.
After ALTEA-space hardware was delivered to NASA, I contributed to asses the ALTEA User Home Base (UHB), where operation data are collected and the communications with NASA take place. Before the start of the mission operation I partecipated to the NASA simulations aimed at the reproduction of flight operations.
ALTEA was finally brought on board the International Space Station within the STS-121 Shuttle mission on the July the 4th 2006; in the last chapter of this thesis the actual flight operations are described and the results of analysis performed on the first scientific data gathered onboard ISS are showed. About three month data were analyzed in this thesis and the first results include, among others, the study of the particle rate, the different particle fluxes measured by the six particle detectors and the first calculation of relative nuclear abundances.
I contributed to realize and test pre-processing and analysis tools used both for calibration and for flight operations. These tools were developed using several programming languages (C, VC++, VB, IDL)

Ep. #024 - Veronica Strang
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Water, water everywhere. The human sciences have become animated by the politics, ethics and materiality of water of late and for good reason. Our guest (11:13) on this week’s Cultures of Energy podcast was one of the first to get this conversation started. Anthropologist Veronica Strang, currently Executive Director of the Institute for Advanced Study at Durham University, is the author of The Meaning of Water (Oxford, 2004) and Water: Culture and Nature (Reaktion, 2015) and a recipient of UNESCO’s International Water Prize. We talk about how the transgressive and transformative properties of water cut across cultures and how its material liquidity complicates our cultural and legal understandings of ownership and property. Veronica explains why we have to think water across scales, from its mediation of individual bodies to how its flows form communities. We talk about the infamous case of Bolivia’s water privatization, efforts to enclose water resources across the world and how contemporary politics of water are undermining democracy. Veronica also reminds us though that efforts to centralize control over water are ancient and that the movements that are now seeking to decentralize water resources also have hope. In closing we discuss cosmological and mythological water beings ranging from rainbow serpents to Chinese water dragons to the Lambton Worm, reputed to live in Durham’s own River Wear. Is our concern with hydration and floods these days informed by the moral economy and sacred vitality of water? Has urbanization caused us to lose touch with the hydrological cycle that so powerfully informed the cultural imaginations of our ancestors? Pour yourself a glass of water and listen on
The ALTEA experiment onboard the International Space Station
No full textThe knowledge of the composition of the radiation environment is an important information for all the radiation safety issues needed for the planning of future long manned space missions. The ALTEA detector is on board the International Space Station since July 2006 and during this period it has performed a detailed measurement of the radiation environment. In this paper we present a summary of past measures and results
Radiation survey in the International Space Station
No full textThe project ALTEA-shield/survey is part of an European Space Agency (ESA) – ILSRA (International Life Science Research Announcement) program and provides a detailed study of the International Space Station (ISS) (USLab and partly Columbus) radiation environment. The experiment spans over 2 years, from September 20, 2010 to September 30, 2012, for a total of about 1.5 years of effective measurements. The ALTEA detector system measures all heavy ions above helium and, to a limited extent, hydrogen and helium (respectively, in 25 Mev–45 MeV and 25 MeV/n–250 MeV/n energy windows) while tracking every individual particle. It measures independently the radiation along the three ISS coordinate axes. The data presented consist of flux, dose, and dose equivalent over the time of investigation, at the different surveyed locations. Data are selected from the different geographic regions (low and high latitudes and South Atlantic Anomaly, SAA). Even with a limited acceptance window for the proton contribution, the flux/dose/dose equivalent results as well as the radiation spectra provide information on how the radiation risks change in the different surveyed sites. The large changes in radiation environment found among the measured sites, due to the different shield/mass distribution, require a detailed Computer-Aided Design (CAD) model to be used together with these measurements for the validation of radiation models in space habitats. Altitude also affects measured radiation, especially in the SAA. In the period of measurements, the altitude (averaged over each minute) ranged from 339 km to 447 km. Measurements show the significant shielding effect of the ISS truss, responsible for a consistent amount of reduction in dose equivalent (and so in radiation quality). Measured Galactic Cosmic Ray (GCR) dose rates at high latitude range from 0.354 ± 0.002 nGy/s to 0.770 ± 0.006 nGy/s while dose equivalent from 1.21 ± 0.04 nSv/s to 6.05 ± 0.09 nSv/s. The radiation variation over the SAA is studied. Even with the reduced proton sensitivity, the high day-by-day variability, as well as the strong altitude dependence is clearly observed. The ability of filtering out this contribution from the data is presented as a tool to construct a radiation data set well mimicking deep space radiation, useful for model validations and improvements
