One of the numerous lunar viewing forums, discussing the absence of a toilet in the "moon missions:
The astronauts had special rites in which solid and liquid body waste was collected. And then they transferred all this into a special sealed package, which they dropped near the module after landing (a photo of some bag near the lunar module).
WOW: No, well, I just imagine this picture - some shit, very similar to a flying chicken from cardboard and scotch, arrives on the moon, the door opens and a bag with the man flies out of it, which in the vacuum explodes fairy and clothes the whole chicken. With a little weather, some body comes out of the chickenhouse, slides down the ladder and proclaims a "huge leap for all mankind." With full pants, I’m on the table!
