Moreover, it had a fundamental long-term importance from a technological point of view, because of the great stimulus it provided for space research not only in the Soviet Union but above all in the United States. In fact, a few years later, President Kennedy, in a famous speech, promised the full support of the U.S. government for the development of the necessary technology to reach the moon before the end of that decade. In a far less transcendental way, the same event had a direct infl uence on my life. October 4 was also my birthday. I was fi fteen, an age at which I was still very fl exible and ready to wonder at and absorb all that the world could offer. It was my penultimate year at school, and I was planning to follow in my father’s footsteps and become a civil engineer, and later go on to work in his construction fi rm. However, the marvel of Sputnik’s launching made me dream, and I began to think that “when I grew up” I would like to work in space research, a fi eld that was opening up at that very moment. When I left school the next year, I enrolled in physics instead of engineering, and my road ix to space research had begun. This episode in my life serves simply to illustrate, from a very personal point of view, how amazement and wonder at the world that surrounds us and at
