Team Roles and Specializations Project Manager: Shae Williams Project Systems Engineer: Clifford May Science Payload Engineer: Michael Thomas Flight Systems Engineer: Kevin Diggs Mission Systems Engineer: Michael Sullivan Principal Investigator: Alexander Bazilevskiy Traj/Performance: Michael Sullivan Mass & Structures: Clifford May Prop/Power: Kevin Diggs CAD: Shae Williams Cost: Michael Thomas

Scientific Philosophy: 

Scientific Philosophy Group Objective: Advance understanding of Martian geology. Deep cores a favored location for learning about Martian geology… Why not use the large hole on Mars naturally present?
