How does going to the bathroom in space work? By: Stephanie Watson. A wide-angle view of the Orbital Workshop waste management compartment. The actual toilet's down the hall, to your right.

Spangenberg, Ray and Diane Moser. Cite This! Try Our Crossword Puzzle! In , Alan Shepard became the first American in space. His trip was supposed to be short, so there was no plan for pee.
But the launch was delayed for over three hours after Shepard climbed into the rocket. Eventually, he asked if he could exit the rocket to pee. Instead of wasting more time, mission control concluded that Shepard could safely pee inside his spacesuit. The first American in space went up in damp underwear.
The original toilet was designed in for men and was difficult for women to use: You had to pee while standing up. To poop, astronauts used thigh straps to sit on the small toilet and to keep a tight seal between their bottoms and the toilet seat. To prepare for its eventual use in space, the toilet has been extensively tested on the ground, with engineers orienting it in many different directions to ensure the suction worked. The new device is expected to get a lot of use over the next several months as there will be five crew members in the U.
Using the bathroom in space may not be the most glamorous aspect of space travel, but astronauts today have it a lot easier than some of those who flew in the early days of space travel.
The sleeves were replaced daily and spills happened quite frequently. Pooping was even messier; astronauts essentially taped a bag to their butts which collected their business—if they were lucky.
During the mission, Stafford had to warn his crewmates that he missed his mark. The early days of spaceflight were messy and often very smelly during bathroom breaks. Scientists knew little about how the space environment affected the human body, so NASA even requested that its astronauts bring back all of their poop bags for analysis.
When NASA launched Skylab in the s, it was the first time an apparatus loosely resembling a toilet was installed on any U. The rudimentary unit consisted of a hole in the wall that sucked urine and feces into collection bags. Afterwards, the crew would have to dry their feces in a specal compartment to bring back to Earth. That commode was essentially a metal bowl with a suction hose and a funnel to use for urine.
In June, the agency put out a call looking for potential designs for a future lunar toilet. The agency is also researching the notion of how to extract water from solid waste so it too can be recycled for crewed missions. With the older latrine models on the ISS, astronauts urinate into a handheld funnel and defecate into a device that looks like a smaller version of a traditional toilet seat.
A fan inside each apparatus suctions the waste away from the body, an important function in an environment where everything floats. Hold the funnel too close to the body, cutting off airflow, and liquid can end up pooling near the top. Lose contact with the seat, and waste might escape. Forget to turn on those fans before you start, and things can get messy.
They wear diapers for that activity, in rehearsals and during the real thing. Koch showed her how to situate herself and which handrails and foot restraints helped most. The newest lavatory was designed specifically with female anatomy in mind. In this way, the Universal Waste Management System is more than a toilet.
