29th International Mars Society Convention

At the University of Southern California, the world’s largest gathering dedicated to human Mars exploration. For nearly three decades, the International Mars Society Convention has brought together the scientists, engineers, entrepreneurs, students, and advocates working to make humanity a multi-planetary species. The 2026 convention returns to the University of Southern California for three days of plenary talks, technical sessions, panels, and debate.

Whether you’re a researcher presenting new work, a student exploring a career in space, or simply someone who believes in the future on Mars — there’s a place for you here.
