[Conference] 20 November 2025 - Roland Lehoucq: can we really stay alone on Mars?
Dans le cadre des conférences conjointes d’Avignon Université et du Café des Sciences, Roland Lehoucq, astrophysicien au Commissariat à l’énergie atomique et aux énergies alternatives (CEA), présentera une conférence sur le thème : « Peut-on vraiment rester seul sur Mars ? » le jeudi 20 novembre 2025.
The film Alone on Mars (R. Scott, 2015) shows us how the hero, Mark Watney, tries to survive on Mars using his ingenuity and scientific knowledge. With NASA announcing a manned flight to Mars in the next few decades, it's interesting to consider the question of survival for a group of human explorers in the hostile conditions that prevail on the surface of the Red Planet. We can't help but wonder whether what the film shows is realistic. Can a Martian storm do so much damage? How can water be produced on Mars? Can potatoes be grown there? What does the surface of Mars really look like? Together, let's try to answer the question "Can we stay alone on Mars"?
Roland Lehoucq is an astrophysicist at the CEA in Saclay. He is the author of a number of popular works, including Science at the movies and Doing science with Star WarsSince 2012, he has chaired the international science fiction festival Les Utopiales in Nantes.
