Abstract
Return of samples from the surface of Mars has been a goal of the international Mars science
community for many years. Affirmation by NASA and ESA of the importance of Mars exploration led the
agencies to establish the international MSR Objectives and Samples Team (iMOST). The purpose of the
team is to re-evaluate and update the sample-related science and engineering objectives of a Mars
Sample Return (MSR) campaign. The iMOST team has also undertaken to define the measurements and
the types of samples that can best address the objectives.
Seven objectives have been defined for MSR, traceable through two decades of previously
published international priorities. The first two objectives are further divided into sub-objectives. Within
the main part of the report, the importance to science and/or engineering of each objective is described,
critical measurements that would address the objectives are specified, and the kinds of samples that
would be most likely to carry key information are identified. These seven objectives provide a
framework for demonstrating how the first set of returned martian samples would impact future
martian science and exploration. They also have implications for how analogous investigations might be
conducted for samples returned by future missions from other solar system bodies, especially those that
may harbor biologically relevant or sensitive material, such as Ocean Worlds (Europa, Enceladus, Titan)
and others.
