Mars Geophysical Network

The science objectives of the Mars Geophysical Network (MGN) mission study were divided into two categories: primary (the science floor that would need to be addressed to justify the mission) and secondary (additional goals that prospective principal investigators would reasonably add, given sufficient resources). By request from the Planetary Science Decadal Survey Mars Panel, this study addressed only the primary objective -- to characterize the internal structure of Mars to better understand its early history and internal processes affecting its surface and habitability.
