Kerbal Space Program - Interstellar Quest - Episode 28 - RAPIER Engines HD

With our kerbals on the way to Duna they have also become the first kerbals to enter interplanetary space and as such we are rewarded with science! Just enough science to unlock the new RAPIER engine and attempt to design a spaceplane capable to taking a small payload into orbit and returning to base.
