Cap

Cap is the leader of the eager Astronaut candidates, including Skip and Rook. He and the two other astronauts attempt to qualify for their first lunar mission while undergoing vigorous training. Along the way, they question their own sanity and trust in each other.

"Dry"
Cap pretends not to know how their crew has burned through an entire month's store of water within just a week when Rook asks how this is possible. He later suggests making drinkable salad dressing with vinegar and vegetable oil, and when he tastes the water from the urine recycler, he spits it out and complains of its salinity.
