The name of their spaceship is "Raza". This is also a Spanish word which translates into English as "Race" (as in human race, not fast cars or horses). In Latin America, "Raza" also refers to Latinos descended from Spaniards and indigenous people.
The ship's nomenclature, "Raza," likely refers to the Latin term tabula rasa, meaning blank or wiped slate. The name clearly alludes to the crew's mneumonic deficiencies, they're apparent mental reboots.
