A Maximum Absorbency Garment (MAG) is an adult-sized diaper with extra absorption material that NASA astronauts wear during liftoff, landing, and extra-vehicular activity (EVA) to absorb urine and feces. It is worn by both male and female astronauts. Astronauts can urinate into the MAG, and usually wait to defecate when they return to the spacecraft. However, the MAG is rarely used for this purpose, since the astronauts use the facilities of the station before EVA and also time the consumption of the in-suit water. Nonetheless, the garment provides peace of mind for the astronauts. The MAG was developed because astronauts cannot remove their space suits during long operations, such as spacewalks that usually last for several hours. Generally, three MAGs were given during space shuttle missions, one for launch, reentry, and an extra for spacewalking or for a second reentry attempt. Astronauts drink about 2 L (2.1 US qt) of salty water before reentry since less fluid is retained in zero G...
