This archival image was released as part of a gallery comparing JPL's past and present, commemorating the 80th anniversary of NASA's Jet Propulsion Laboratory on Oct. 31, 2016.
Building 264, also known as the Space Flight Support Building, hosts engineers supporting space missions in flight at NASA's Jet Propulsion Laboratory. It used to be just two stories, as seen in this image from January 1972, but then the Viking project to Mars needed more room. The building still serves the same function today, but now has eight floors.
JPL is a division of the Caltech in Pasadena, California.
