* 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.
