    Biographical History

    Born in Olympia Washington in 1943, David Lozier was recruited by NASA Ames in 1965 as he was graduating from Washington State University with a degree in mathematics. He was hired as a civil servant in 1966 to work on the Pioneer Project. Pioneer 6 had launched, but the project needed a computer programmer to debug and finish trajectory codes, which was Lozier’s first role at NASA. His career at Ames spanned 38 years, ending with his retirement in 2005. Proud of his work, he collected articles, excerpts, photographs, and ephemera relating to each of his projects and others that interested him, with an eye toward detailing his legacy.
    Lozier worked on Pioneer Project missions 6, 7, 8, 9, E, 10, 11, 12, and 13 sending four spacecraft around the Sun, two to Jupiter and Saturn, a Venus orbiter that lasted 14 years, and four probes into the atmosphere of Venus (collectively known as Pioneer Venus). The Pioneer Projects focused mostly on interplanetary space probe exploration. Pioneers 6, 7, 8, 9 and E (1965-1968) were created to make the first comprehensive measurements of the solar wind, solar magnetic field and cosmic rays. Pioneers 10 (1973) and 11 (1979) were the first to leave the solar system. Add something about Pioneer Venus? Lozier eventually became Flight Director for the Pioneer Program and received many honors and awards for his work on that project and others.
    He also worked in mission design for the Lunar Prospector, which was selected by NASA in 1995 as the first of NASA's Discovery Missions, with the primary goal of mapping the surface of the Moon.
    Lozier’s involvement with trajectories sparked his interest in various NASA studies that he didn’t work directly on, including Mars missions, Galileo, Cassini, and other projects that required trajectory analysis. By the end of his career, his specialties included mission analysis and planning, systems engineering, and mission flight design. His technical publications relating to these specialties included several papers published by AIAA regarding Lunar Prospector mission design, Pioneer Venus, and various papers presented at conferences.
    Lozier described himself as follows: "I enjoy travel, reading, hiking and fishing. I like explaining celestial mechanics, trajectories, orbits, and launch rockets to students and people that ask me questions about NASA. I consider myself a rocket man, and a celestial mechanic."
    A full list of his roles follows:
    1998 to 2005: Ames Research Center, Mission Design Engineer, Advanced Missions Branch
    1995 to 1998: Ames Research Center, Trajectory Team Leader, Lunar Prospector Mission
    1989 to 1997: Ames Research Center, Flight Director, Pioneer Project
    1984 to 1989: Ames Research Center, Assistant Flight Director, Pioneer Project
    1983 to 1984: Lewis Research Center, Mission Design Engineer, Shuttle Centaur Project
    1982 to 1983: Ames Research Center, Flight Operations Planning Engineer, Galileo Probe Mission
    1980 to 1982: Ames Research Center, Mission Design Engineer, Space Operations Office
    1979 to 1980: Ames Research Center, Geobased Information Systems Project Manager, Remote Sensing and IR Imaging Technology Utilization branch
    1976 to 1979: Ames Research Center, Mission Analysis and Midcourse Maneuver Operations Planning Engineer, Pioneer Venus Orbiter and Multiprobe Project
    1966 to 1976: Ames Research Center, Payload Integration and Launch Operations Engineer, Pioneer 6-9 and Pioneer 10/11 Projects

    Scope and Content

    This collection comprises nearly forty years of David Lozier's career at NASA Ames, primarily concerning spacecraft trajectory calculation work on various missions within the solar system, starting with the Pioneer 6-9 missions. The collection contains scans and born digital files including photographs; scrapbooks; technical papers; recollections; clippings; correspondence; advisement on an external Pioneer website; mission management documentation and trajectory and other technical data for various missions, including the Pioneers, Lunar Prospector, Mars 2001 Odyssey, Kepler, and others. The born digitial content was created in the 1990s through 2008, while the bulk of the scans are digital copies of items from the 1960s through the 1980s.
