> On Friday 22 May 1992, Goldin announced unexpectedly that the "worm" logo would be replaced by the traditional NASA blue "meatball" logo. It had been replaced in 1975 by the NASA red "worm" logo. By 1997, Goldin had started a largely successful campaign within NASA to eradicate the "worm". He would become infuriated and vulgar whenever he would see a "worm" logo that was not replaced.[2] By 1998 the "worm" logo had entirely disappeared from use both in uniforms and in equipment.
