The fourth installment of this video series discusses how working with gravity, instead of against it, is the easiest way to get something where we want it to go and how NASA’s Space Launch System (SLS) will do this to send missions to Mars. Host Stephen Granade explains how rockets deliver spacecraft into Earth orbit, and how that process resembles and differs from a trajectory to Mars.
