In short: This video follows the Kerbal Space Program mission to Duna, where reaching interplanetary space unlocks the ability to design a specialized spaceplane using the new RAPIER engine.

As the Kerbals reach interplanetary space on their journey to Duna, they earn enough science to unlock the RAPIER engine. This new technology allows for the design of a spaceplane capable of taking a small payload into orbit and successfully returning to its base.
