10 Secrets You Didn’t Know About NASA

Time for some more low-brow stuff, and one of the most infamous radio transmissions in human history.

Seen as the dress rehearsal for the Moon landings, the Apollo 10 mission was the second manned voyage around the Moon. As the crew were getting ready to return to Earth after a successful mission, Commander Thomas P. Stafford uttered the immortal words "Oh - who did it?"

The "it" he was referring to was, of course, a piece of human faeces that was somehow floating through the air inside the module.

After the first doodoo was retrieved via napkin, a second lump of excrement was sighted, causing pilot Eugene Cernan to utter the immortal phrase "Here's another goddamn turd."

The best part about this whole story is that nobody owned up to it. To this day, the truth behind the floating floater remains a mystery. Cernan and fellow pilot John Young have both since passed away, meaning that, if it was one of them, they literally took that secret to the grave.

As for Stafford, if only he'd been the first to have smelt it, then we would have known for sure that he was the one who dealt it.
