NASA's Goddard Space Flight Center operates under dedicated ZIP code 20771 in Greenbelt, Maryland, approximately 6.5 miles northeast of Washington, D.C. Established on May 1, 1959, as NASA's first space flight center, Goddard serves as the nation's largest organization of scientists, engineers, and technologists building spacecraft and instruments to study Earth, the Sun, and the universe. Named for American rocket propulsion pioneer Robert H. Goddard, the center employs approximately 10,000 civil servants and contractors. This postal designation has served the facility for over two decades.
The 1.26-square-mile campus encompasses NASA's premiere space research laboratory, with postal records confirming delivery points for Goddard Space Flight Center and the GEWA contract station. Census data shows minimal residential population (just 3 people with a median age of 66.5), consistent with an employment-focused federal research facility. The Goddard Visitor Center offers free educational exhibits to the public on Thursdays through Saturdays.
Census employment data indicates 827 workers at 21 establishments, though this represents only a fraction of the center's total workforce of 10,000. Greenbelt serves as the valid mailing city for correspondence to NASA Goddard.
