The Apollo 5 mission tested the lunar module in a space environment, in particular its descent and ascent engine systems, and its ability to separate the ascent and descent stages. The descent engine would become the first throttleable rocket engine fired in space. The mission also performed a simulation of a landing abort, in which the ascent
