po­pu­lar­me­cha­nics.com: How Apol­lo As­tro­nauts Took Out the Trash
lisa ruth rand:

Ap­pro­xi­m­ate­ly five mi­nu­tes be­fo­re Arm­strong took his first his­to­ric step, he and Al­drin un­der­took some house­kee­ping fa­mi­li­ar to all Ame­ri­cans. Al­drin han­ded Arm­strong a white bag known as a "jet­t­i­son bag," or "jett bag" for short, full of things the as­tro­nauts no lon­ger nee­ded–the ba­nal det­ri­tus of spacef­light, from food wrap­pers to con­tai­ners of hu­man was­te. Arm­strong drop­ped the jett bag to the sur­face, and la­ter ki­cked it un­der the lu­nar mo­du­le to get it out of the way. Like the gar­ba­ge we throw away on Earth, ho­we­ver, it did­n't just ma­gi­cal­ly di­s­ap­pear. The first pho­to­graph that Neil Arm­strong took du­ring his his­to­ric moon­walk fea­tured the gar­ba­ge bag pro­min­ent­ly in the fo­re­ground.
