Hank Hartsfield, a grizzled air force fighter pilot who had stared death in the eye on many a mission, now faced a man’s worst nightmare—a
Nature finally caught up with me and I floated into the shuttle toilet to face what was truly the most difficult part of any spaceflight—a bowel movement. The toilet provided little privacy. It was situated in the rear corner of the mid-deck on the port side. There was no door, only a folding curtain that could be Velcroed across the mid-deck–facing entry. Another curtain was Velcroed to form a ceiling and isolate the toilet from the upstairs cockpit. The lack of privacy was intimidating. I felt like I was back on my honeymoon, preparing for my first married-life BM. We’ve all been there.
After I was inside the curtained box, I took the advice of shuttle veteran Bob Crippen and stripped naked. “It’s a lot easier to wipe feces off your skin than it is to get it off your clothes” had been one of his STS-1 mission debriefing comments.
I located my personal urine funnel and twisted it on the end of the urinal hose, then loaded a disposable vacuum cleaner–like bag in a can on the left side of the toilet. Used tissue had to be placed in this bag. It could not be put in the toilet since that would require the ass to be lifted, which, in turn, could result in feces being released into the cabin. Suction at the bottom of the can would hold used tissue inside the bag.
I floated over the throne, lifted up on the thigh restraints, and twisted them inward to clamp my body to the plastic seat. Recalling my bore-sight alignment from the camera view in the toilet trainer, I wiggled my body until some freckles on my thighs were properly positioned in relation to the toilet landmarks. I switched on the toilet fan and welcomed the noise it generated. At least some of my BM noises would be camouflaged. Finally I pushed my penis into proper aim at the urinal funnel, reached for the solid waste collector lever, and pulled it back. Directly beneath me the waste opening was uncovered and the feces-steering airflow was activated. Suddenly a very sensitive part of my body was hit with a blast of chilled air. Few things are less conducive to promoting a BM than having cold air jetting around the principal performer in that act. The natural tendency is to clamp shut. But I convinced the orifice in question to ignore the cold gale and let fly. Simultaneously, I held the urine funnel at my front to collect my liquid waste. The vacuum flow into the urinal hose was very effective at sucking away the fluid until my bladder pressure fell. Then the urine refused to separate from my skin and a ball of it grew on the end of my penis. NASA’s engineers had anticipated this aspect of fluid dynamics and had provided a “last drop” feature. By squeezing buttons at the sides of the hose, the suction was boosted and I was able to wet-vac myself of most of the fluid. As the slurping sounds of this operation came through the curtains, Hank hollered, “More than five seconds and you’re playing with it, Mullane!”
The toilet was a bountiful source of male juvenile humor. By far the best toilet joke was pulled by Bill Shepherd (class of 1984). On one of his missions he carried a piece of sausage from his breakfast into the toilet. After finishing a bowel movement, he set the sausage free to float upstairs. As panicked crewmembers ricocheted from wall to wall in a mad retreat from the offending planetoid, Bill chased after it with a piece of toilet tissue. He finally grabbed it and then, to the horror of all, he ate it.
