Nasa existing suits have diapers called maximum absorbency garments
Sources from Washington have added that NASA scientists are developing a new spacesuit that includes a waste-disposal system, which will allow astronauts to remain in their spacesuits for up to six days in case of emergencies. Meanwhile the new suits, called the Orion Crew Survival Systems Suits (OCSSS), will be worn by astronauts on NASA’s Orion spacecraft, which will carry humans beyond low Earth orbit.
Meanwhile the Orion will be equipped with a toilet, NASA is making contingency plans in case of emergencies, including the possibility that the Orion capsule depressurizes and the astronauts have to remain in their suits to survive. Further NASA wants astronauts to be able to survive in their suits for up to six days.
Moreover for urine
collection, the all-male crew members wore catheters that fit over the penis
like a condom, with a tube at the end to collect the liquid, which was pulled
into a bag attached to the outside of the suit. Furthermore there were no
suits, urine-collection systems for women and the female astronauts used
diapers and toilets.
