Despite its proximity to the Sun, Mercury remained largely unexplored, with many questions remaining about its surface features, geological composition, and magnetic field. The scientific community recognized the need for a dedicated mission to study Mercury up close and unlock its secrets.

“We have been plunged into a race for the conquest of outer space. As a reason for this undertaking some look to the new and exciting scientific discoveries which are certain to be made. Others feel the challenge to transport man beyond frontiers he scarcely dared dream about until now. But at present the most impelling reason for our effort has been the international political situation which demands that we demonstrate our technological capabilities if we are to maintain our position of leadership. For all of these reasons we have embarked on a complex and costly adventure. It is the purpose of this report to clarify the goals, the missions and the costs of this effort in the foreseeable future, particularly with regard to the man-in-space program.” From 1960 Ad Hoc Panel on Man-In-Space.
