The National Aeronautics and Space Administration (NASA) has three official insignias: the NASA seal, the NASA insignia (known as the "meatball") and the NASA logotype (known as the "worm"). The logotype was retired from official use from May 22, 1992, until April 3, 2020, when it was reinstated as a secondary logo.
