Donated by David W. Lozier on July 7, 2010 (Accession 2010-016).
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."

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.

Arrangement of the David W. Lozier Papers
This collection is arranged in two series.
- Series I: Scrapbooks and Personal Papers, 1962-2008
- Series II: NASA Work, 1996-2007
The creator's original order was retained for the bulk of the collection.
Digital files were imaged from a DVD-R disk during processing. Unstable file formats were reformatted to stable, widely-adopted
formats such as PDF. Nonconforming characters and spaces were removed from filenames.
I Scrapbooks and Personal Papers 1962 - 2008
Scope and Content Note
This series documents Lozier's personal recollections and research, with particular focus on his time working with the Pioneer
Project from 1966 until 1997, first as an engineer and eventually as flight director.
Contained within are digital scrapbooks in which Lozier, after retiring from NASA in 2005, combined historical images with
his own descriptive text to illustrate his personal experiences in the space program and work done on Pioneer 6 through Pioneer
Venus, as well as Lunar Prospector. Several documents demonstrate Lozier's admiration for the Pioneer Project Manager, Charles
Hall, who led the project from 1962 until 1980. Lozier advised on Mark Wolverton's 2004 book about Pioneer interplanetary
probes, The Depths of Space, and this series contains some of their correspondence in which Lozier gives historical context
and clarification to Wolverton, as well as a draft of Wolverton's article about Pioneer Saturn, "Pathfinding the Rings." Lozier
also advised on Hamish Lindsay's webpage about the Pioneer missions, part of a website that honors the Deep Space Network
work performed at the Honeysuckle Creek Tracking Station in Canberra, Australia. Also included: Lozier's curriculum vitae,
retirement business cards, excerpted project data, and short autobiographies; photographs including personal snapshots of
himself, colleagues, flight hardware, and ephemera from the 1960s through the 2000s, as well as images of favorite books a
Pioneer Project bibliography he compiled, trajectory designs, and events; and Lozier's collected clippings and newsletters
relating to the Pioneer Project over many decades, from both NASA and external publications including Star Date, Air and Space,
Mercury, the Journal of the British Interplanetary Society and others, for his personal research and reference.
II NASA Work 1996 - 2007
Scope and Content Note
This series contains working files mainly relating to several flown and proposed solar system exploration missions that Lozier
worked on during the last decade of his tenure at Ames. These cover a range of endeavors, such as: lunar rover, impactor,
penetrator and sample return (Victoria, Lunar Prospector, Polar Night); Mars rover, airplane, and communications networks
(e.g., Mars Exploration Rover, Express, Global Surveyor, Aeroplane); Venus probes (Evening Star, Venus Surface and Atmosphere
Geochemical Explorer); and space telescopes using spectroscopy to address questions in astrobiology (Kepler and Astrobiology
Explorer).
Files included are mission design and analysis documentation and data, concept studies, proposals, technical papers, and some
notes, meeting minutes, correspondence, plans, timelines, schedules, reference documents, press kits, and photographs. Many
file directories include trajectory plots, analyses, and related data generated by Lozier and colleague Khaled F. "Ken" Galal.
