Alexander Gerst talks Blue Dot

ESA astronaut Alexander Gerst introduces his mission name and logo: Blue Dot. Inspired by an image of Earth taken by the Voyager probes at the edge of our solar system. From afar our planet looks like a fragile spacecraft that needs protecting -- it is the only spaceship we have.

Alexander will fly to the International Space Station and stay on our orbital outpost for six months running scientific experiments and maintaining the facility.
