To Luca Parmitano, who explores the future by overcoming challenges and barriers without ever sparing himself. An enthusiastic pioneer who engages and excites the new generations; the first Italian to perform a space walk, he has distinguished himself for his courage as a pilot and as an astronaut; a protagonist of the adventure of space exploration, to extend human presence beyond the boundaries of the Earth, he tells us that our planet, seen from above, has no boundaries, and that it is a fragile treasure to be protected.
