Named in honor of Anthony Spear, manager of the successful Pathfinder Project. In his 37 years at the Jet Propulsion Laboratory he has been associated with several successful space projects, usually in a management position. These include the Magellan and VOIR projects to orbit Venus, and Seasat, the first earth satellite to make images of the surface of the oceans using radar. His association with Mars exploration goes back to the beginning of the program, when he was Cognizant Engineer for the command system of Mariner 4, which in 1964 became the first spacecraft to reach Mars successfully.
