As a means to double their chances of controlling the outcome of the colony as well as a covert show of force and resources, America commissioned the Ingles for Mars as well. However, as the Ingles was designated the ship of the devout, America made quick work of packing the crew with Atheists to minimize the chances of a holy war on one of their ships.
These are the brave men and women assigned to man stations on the ships, ferrying the equally brave men, women and children, who shall colonize Mars to their destination. Some are there for a round-trip to Mars, then right back to Earth. Still others are not just officers, but colonists, themselves.
