I have always dreamed of being a cosmonaut, of discovering the universe, its secrets, its immensity and its magic. As a kid, I made cardboard rockets and paper spaceships. I spent hours staring at the night sky, looking for stars, planets, and life. Of course, my imagination made me travel, of course, I saw all the planets, even some that don't exist, I saw life too... then I grew up (a little) , I matured (a little...) but above all, I ended up finding the meaning of these childish searches.
