The Aurora Programme

Pierro Messina & Franco Ongaro Directorate of Strategy and External Relations, ESA, Paris

Introduction

A manned mission to is bound to become a reality over the next decades. It is very likely to be an international mission carried out by those players who have developed the technologies and expertise needed to master the challenges of landing humans on Mars and returning them safely to the Earth. Europe has been at the forefront of space endeavours for more than 30 years, with many successful missions and key contributions to international programmes. Its participation in the International Space Station, the experience acquired with the European astronauts, with leading-edge scientific missions and notably with the recently launched and its , are all good examples of the degree of maturity that Europe, through ESA and its Members States, has gained as a result of its investment in space activities and the expertise developed within its work force and the scientific community. Exploring Mars is still a risky business, however, as the low success rate of the robotic missions conducted to date is a constant reminder. Less than a third of the unmanned missions so far launched to the Red Planet have fulfilled their goal. Consequently, there is still much to be done before we can feel sufficiently confident to commit to sending humans to explore the more distant bodies in the Universe and to land on Mars.
