  2. An Outstanding Question Did Mars really have a warm and wet environment in its early days?? To answer the above question: Need to fully understand the evolution of Martian atmosphere, the water, and its climate. The atmosphere to solid-body interactions are significant also. The MELOS mission challenges the following 3 science objectives.

  3. Mars Exploration with a Lander and Orbiters • Orbiters • Comparative meteorology (on a 3-axis-stabilized orbiter) and atmospheric escape studies (on a spin-stabilized orbiter)‏ • Imaging cameras and a plasma science package • A Lander • Seismic measurements (+ heat flux) for interior structure studies • Configuration of the lander & possible science packages are being discussed by researchers in the wider field In-situ measurementsof escaping atmosphere Observe “global” meteorology from near apocenter Seismic measurements, near-surface turbulence and gas composition

  4. Mass Budget (Very Preliminary)‏

  5. Mission Schedule (Preliminary)‏
