A simple science SSTO designed to go to Duna and back as easily as possible. The SSTO has the pilot in the cockpit on the front of the craft (who can get in and out of the cockpit surprisingly enough), while the scientist is in a Mark1 command pod in the cargo bay, this method saves on mass and reduces drag. The craft is powered by a single RTG. To ascend, rotate at 120 m/s, or 90 m/s if you fly off the sides of the runway (which is a problem for some reason). Pitch up to 10 degrees and let the craft ascend until you reach 8-9 kilometers, at which point hold prograde until the craft has pitched down to 5 degrees then switch back to stability assist and let the craft accelerate. once you pass 25-26 kilometers toggle the R.A.P.I.E.R.s and burn until they run out of oxidiser, shut them down, than activate the nuclear engines, once apoapsis goes above 50 kilometers hold prograde, by the time apoapsis reaches 70 kilometers the periapsis will be above the ground.The rear Mark2 to 1.25 adapter is only partially filled with oxidiser, and it is not allowed to flow to the engines, this will be used on the ascent from Duna. This craft lands mostly vertically, and is aided by parachutes which slow it down to 30 m/s. Before landing, control authority on the control services will have to be slided into the negatives so they can work while the craft its going backwards (just remember to set them back to normal before taking off). Burn the nuclear engines for the last bit of decceleration, try to pitch downward so you land on the wheels at the last second. Find a nearby hill, and use the last bit of oxidiser to get into the air. The ascent should be easy, as the craft in nuclear mode has well over 1 thrust to weight. You should get you kerbin encounter with over 700 m/s of delta V left. Allowing you to save yourself from the treacherous interplanetary speed aerobraking, plot your landing spot, or fly around once in the atmosphere if you messed up your landing aproach and ended up over the wrong continent (like I did, hence the 0 liquid fuel remaining). This craft was designed in every way to be easy to use, even by far less experienced players.
