WORD OF THANKS This dissertation would have never seen the light of day without the help of a number of people. First, I would like to thank my promotor Prof. Dr. Maarten Vansteenkiste, my co-promotor Prof. Dr. Wim Beyers, and Prof. Dr. Bart Soenens. Maarten, I remember, when I was studying at the KU Leuven and I needed a promotor for my master thesis, I send you an email and you accepted. A few months later, I send you the first draft of my manuscript. You replied by asking me who I was and what I wanted, saying you had very little time. Not much later, my rather unfortunate first impression from this encounter was quickly eradicated. From the day we finally met until the day I handed in this dissertation, you supported me unconditionally, showed faith in my work and belief in my capabilities. You mastered that delicate balancing exercise that is autonomy-support, and you knew exactly when to hold and when to push. You talk the talk and you walk the walk. Thank you. Wim, thank you for your continuous support, meticulous attention to detail, and most of all, your boundless patience for my non-existing aptitude for statistics. Bart, thank you for the much appreciated guidance and feedback in our work together, and also your sense of humor, at times quite dark and cynical, which has uplifted my working days on many occasions. To our IT technician, Steven Vandenhole, thank you in particular for the set-up of the technical tools for the experimental studies of this dissertation. Without you, I would have been stuck after the Chapter 1. Prof. Dr. Alain Van Hiel, thank you for trusting me to transform your students into proverbial Guinee pigs. Frank De Winne, thank you for teaching me how to communicate like a Russian: brief and to-the-point. Prof. Dr. Christoffel Waelkens from the KU Leuven, thank you for founding the Master of Space Studies. You mentioned once that, what fascinated you most about astronomy, was the discovery that the laws of physics are the same everywhere in the Universe (I’m sure you put it more eloquently). In a similar way, I believe the laws of psychology are universal, equal for both man on Earth and astronaut in space. To my colleagues, Beatrijs Vandenkerckhove, Lisa Dieleman, Joachim Waterschoot, Charlotte Schrooyen, Branko Vermote, Michiel Boncquet, Nele Flamant, Nele Laporte, Sofie Morbée, Elien Mabbe, Nathalie Coorevits, Nathalie Aelterman, Mieke Samyn, Jolene Deeder, Jochen Delrue, Gert-Jan De Muynck, and Katrijn Brenning, I am grateful for having had the chance to get to know such kind and sensible people. To the most wonderful friends a person could ever hope for, Jo Nys, Fleur De Pauw, Suk Coene, Kim Walckiers, Frederik-Jan Roose, Céline De Weerdt, Xavier Teirlynck, Gregory de Corte, Lien Bontinck, Florence Macharis, and Filiep Verhaeghe, thank you for being born in proximity to me and around the same time. To my friend and colleague, David Schrans, I’m afraid I lost the awesome space T-shirt you gave me when I got accepted at the KU Leuven. I am hereby giving you an excellent opportunity to buy me a new one. Also, thank you for insisting I should “talk to Stonecoffin” five years ago. Papa, Maman, Pierrot, Fanfan, merci pour votre support durant toutes ces années, et je ne parle pas seulement de ces quattre dernières. Papa, voici ce qui se passe quand tu laisses traîner tes Ciels et Espaces. Milad ‘Miguli’ Nasri Goortani, TABLE OF CONTENTS General Introduction.

Unlike other candidates with astrophysical, engineering, or law and policy backgrounds, I was asked to motivate my application during an intake interview. After all, what does psychology have to do with space exploration? One of the master’s courses, Questions in Space Studies, was taught by former Belgian astronaut and ISS crew commander Frank De Winne. I remember him saying, much to my surprise, that good astronauts are people who can refrain from taking initiative, since their primary function is to follow orders from the ground. To illustrate this point, he elaborated on a personal anecdote regarding a rather annoying episode during one of his ISS missions: in the middle of a technical task, he encountered an obstacle not accounted for in the written instructions accompanying the task. Although the solution was clear, and the problem simple and easy-to-fix, as an astronaut, he was not allowed to take the decision to deviate from instructions and proceed with solving the issue himself. Instead, he had to alert Mission Support, and the job had to be postponed until they had given their green light, which could easily take several days. However, the sense of frustration for crew members that can arise from lacking decision-making authority in space was, to the best of my knowledge, never mentioned before in scientific literature on the psychological issues in space (see Kanas & Manzey, 2008, for a review). A potential reason for that became clear to me, when Frank mentioned that, generally speaking, astronauts are not too keen on psychologists, since they regard them as the people who can stand in their way of getting appointed to a flight. It is true that, in space agencies, psychologists mainly hold the task of selecting candidates fit to sustain the multiple thrills and challenges of spaceflight. As such, their main responsibility is to “weed out those candidates who might not be suited to training, working, and living in the extreme environment of space” (Anania, Disher, Anglin, & Kring, 2017, p. 1). During actual space missions, private phone call appointments between astronauts 2 GENERAL INTRODUCTION and a psychologist are scheduled at a regular interval (called Private Psychological Conferences, or PPCs), in case an astronaut would be in need of psychological support. However, according to Frank De Winne, astronauts rarely make use of these opportunities, and instead prefer to confide their issues with partners, family members, or friends. After all, one wouldn’t want to be deemed psychologically unfit for the next flight! In fact, astronauts seem to be reluctant to utter dissatisfaction or admitting issues with adaptation to their new work environment in general, as exemplified by the following entrees in astronaut journals (Stuster, 2016): “I was pissed because I saw zero reason to record me (doing nothing). Not even moving, just standing. Plus, there was Ku coverage so the ground could have recorded it. Anyway, I wanted to call down and ask why. Cardinal error for a crew, and luckily both my crew mates jumped on me and talked me out of it” (p. 16). “Telling the ground that it took longer to perform a task than scheduled is an admission of lack of ability” (p. 24). “What is scheduled is what is expected, and another astronaut probably got all this work done and on time on some past mission. No one wants to be seen as a slacker or as incapable (or as a complainer)” (p. 24). “(It bothers) me how the ground treats the crew. We work trivial and mundane tasks for weeks and even still, they do not trust us to do the simplest of things. Then, when we get frustrated we are labeled as hard to work with” (p.
