Lionel Suchet

Chief Operating Officer


Lionel Suchet is a graduate of the Ecole Polytechnique engineering school and an Ingénieur Général de l’Armement (IGA, armaments engineer). He is currently Chief Operating Officer of CNES.
He gained his first experience of the space sector in human spaceflight, devoting the first 15 years of his career at CNES to this domain.
From 1989 to 1992, he was responsible for Safety and Human Factors for Michel Tognini’s Antares spaceflight mission on the Mir space station. He was subsequently project leader for the next three missions to Mir: Altair (1992 to 1996), Cassiopée, which flew France’s first female astronaut (1993 to 1996), and Perseus, a long-duration flight lasting 188 days (1999). He went on to head the agency’s International Space Station Utilization division, where he oversaw the Andromède (2001) and STS-III (2002) missions, the latter being the last spaceflight by a CNES astronaut.
At the same time, he set up the CADMOS centre for the development of microgravity applications and space operations, today the centre in charge of human spaceflight physiology for all of Europe. CADMOS also coordinates all of CNES’s microgravity activities.
In 2004, Lionel Suchet branched out into the field of Universe science, becoming head of the department tasked with developing CNES’s astronomy, planetology and life and material sciences projects.
In 2008, he was appointed head of the sub-directorate in charge of developing orbital systems projects for Universe sciences, altimetry and space oceanography, telecommunications, navigation, Earth observation and defence. In total, this sub-directorate was responsible for 50 projects, all of them with international partners.
In 2011, he was appointed Deputy Director of the Toulouse Space Centre, coordinating all of the centre’s cross-cutting activities, i.e., R&T, technology roadmaps, technology and industry policy, preliminary project planning and regional relations.
From 1 January 2016, he was appointed Director of Innovation, Applications and Science (DIA), the new directorate tasked with supporting the interests, requirements and challenges of all potential users of space data and missions, and planning and proposing CNES’s future orbital systems with a view to nurturing creativity and driving innovation.
Since 28 August 2017, Lionel Suchet is Chief Operating Officer of CNES with functional authority over all of the agency’s activities.
Special Advisor to the President of the International Astronautical Federation (IAF). Lionel Suchet holds the ranks of Knight of the Legion of Honour and Knight of the National Order of Merit in France, and Knight of the Russian Order of Gagarin. He has also been awarded France’s National Defence Medal.
A graduate of France’s Ecole Polytechnique engineering school and national aerospace school ENSAE, Mr Suchet is an IGA armaments engineer (2nd section) and was an intern at the 66th national session on defence policy at IHEDN—the French institute of higher defence studies.
