Rob Manning (b. 1958) was the Flight System Chief Engineer for the successful Mars Pathfinder mission at JPL. He was responsible for all technical aspects of the Pathfinder spacecraft. He also led the team that designed, developed, tested and operated Pathfinder's very successful entry, descent and landing system.
