A microgravity urine collection apparatus may include a bellows defining an internal chamber having a selectively adjustable volume. The bellows may include an inlet and an outlet. The microgravity urine collection apparatus may further include a first valve coupled to the bellows and configured to selectively control fluid flow through the inlet. The microgravity urine collection apparatus may also include a second valve coupled to the bellows and configured to allow fluid flow out of the bellows via the outlet and prevent fluid flow into the bellows via the outlet.
