What is the most kerbal way of travelling around the kerbolar system? When I was asked this, all I could think of was 'Orion'. Nuclear pulse rockets. They fire nuclear bombs behind the craft propelling it into the air. Strangely enough, this is a craft that is within our grasp of technology, and it should obviously be within the kerbals grasp too! I understand that there is a mod that added this part, and Scott Manley also did a video on it (link below). I want to hear your thoughts on this kerbal propulsion idea. Cheers, PugSpaceProgram
