The situation is suboptimal but manageable, according to the astronauts. Due to a fault in the toilet of the SpaceX capsule, the astronauts will have to relieve themselves in diapers, until further notice. Regarding the toilet leak, the problem was first noted during SpaceX's private flight in September, when a tube detached itself and spilled urine under the floor plates. SpaceX fixed the toilet in the capsule awaiting liftoff, but deemed the one in orbit unusable.
Engineers determined that the capsule was safe for the return trip, so there is no risk.
Megan McArthur and her three crewmates will spend 20 hours in their SpaceX capsule, from the moment the hatches close to the planned landing Monday morning.
