Questions related to the delivery of water and the escape of the Martian atmosphere and its water inventory will be discussed. The session also adresses questions related to the young Sun and its influence on the early Martian atmosphere and escape processes, as well as climate change and the role of atmospheric protection by the Martian magnetic field during the first Ga after the planets origin. Ideas for future Mars missions which may help to understand these fundamental questions will also be discussed.
