Dana Ulery

First Female Engineer at NASA JPL & Scientific Computing Pioneer

Biographical Overview

Broke ground in 1961 as the first female engineer hired at NASA's Jet Propulsion Laboratory (JPL). She developed real-time trajectory tracking algorithms and scientific simulation software for the NASA Deep Space Network, supporting the Ranger and Mariner planetary space exploration missions.

"When I was hired at JPL in 1961, women were called "computers." I told them I was an engineer, and that was the title I kept."

Historical Context & Impact

In short

When Ulery joined NASA JPL in 1961, women mathematicians were routinely classified as low-level clerical workers. Ulery insisted on receiving the formal title of System Engineer, becoming the very first woman to hold an engineering post in JPL's history.

Key Technical Breakthroughs & Inventions

Deep Space Network Trajectory Tracking (1961–1970) Programmed real-time tracking and orbit determination algorithms on IBM 7090 and 7094 mainframes for NASA's Deep Space Network tracking stations.

Planetary Mission Telemetry (Ranger & Mariner) Developed real-time telemetry decoding systems that received and calculated coordinates for America's first unmanned lunar and Martian probes.

U.S. Army Research Laboratory Chief Scientist Served as Chief of the Computational Sciences Division at ARL, directing defense high-performance computing and distributed simulation software.

EDIFACT Electronic Data Standards Led the international Pan-American standardization of UN/EDIFACT electronic data interchange formats for computerized commercial trade.
