For the time being, only our robotic “extensions” have been orbiting around or rolling on Mars. We should be proud of them and thankful as they have performed an amazing work since the Viking twins first landed in the seventies. Exploring Mars is an iterative process. Each time, with each mission, we get answers to questions, answers which raise new questions and trigger new missions, each time more sophisticated, capable and precisely dedicated. The result is that Mars is the best known planet in the Universe, apart Earth of course, and all this data gathering, all this thinking and writing, and the conceiving of new launchers or new machines, including life support systems, has prepared the ground for sending out to Mars our most performing and precious machines, Men. We are ready!
