Scientific paper

The nature and origin of the two moons of Mars, Phobos and Deimos, are outstanding unknowns. Solving this mystery is considered the single most important science goal to be addressed in their exploration [1]. When considered in the broader and longer-term context of the human exploration of Mars, human missions to Phobos and Deimos offer exciting intermediate opportunities for science. Four key science objectives can be met by humans, that would be difficult to achieve well by robotic means alone: i) Collect samples representative of the bulk of Phobos and Deimos; ii) Image in detail the subsurface and interior of Phobos and Deimos via seismic tomography; iii) Drill deep (>5m) into Phobos and Deimos to investigate their interior and extract subsurface samples; iv) Search for accreted materials in the regolith of Phobos and Deimos that might have originated in the asteroid belt or on Mars.
