The activity 'Small Satellite Missions to Mars (S2M2)' is an early-phase architecture study of a potential low-cost mission to Mars as further step in the Mars exploration roadmap developed by ESA.

A potential implementation from industry’s point of view was assessed, applying the strict design-to-cost philosophy by fostering strong reuse of an available OHB platform. Trade-offs were performed for assessing a low-cost mission profile targeting the programmatic constraints that were input to this study.
