What makes humans unique, there are many theories. Some say it's langage or tools. Others say it's logical reasonning. They obviously haven't met many humans. I believe what makes us unique is transcending our limits. Gravity pins us to the ground, but I just flew to America. I lost my voice, but I can still speak thanks to my voice synthetiser. How do we transcend these limits ? With our minds and our machines. The limit that confronts us now is the great void between us and the stars. But now we can transcend it. With light beams, light sails and the lightest spacecraft ever built; we can launch a mission to Apha Centauri within a generation. Today, we commit to this next great leap into the cosmos. Because we are human, and our nature is to fly.
