In this historical photo from the U.S. space agency, the Retro and Posigrade Package for the Mercury spacecraft is fitted on Sept. 16, 1960. This was used to de-orbit the spacecraft at the end of mission.

The National Advisory Committee on Aeronautics (NACA) was a precursor to NASA. The NACA was created by Congress in 1915.
