Shuttle-Derived Vehicle art

I have added the full-rez version of this to the 2015-07 sub-folder of the APR Patreon “Extras” folder on Dropbox. What is depicted is a 1985 Martin Marietta design for an Unmanned Launch Vehicle, a Shuttle derived vehicle that replaced the Orbiter hanging off the side with an inline payload shroud up top and a small propulsion/avionics module that would have three SSME and two OMS engines, in much the same positions as the Orbiter engines. This would allow the booster to lift off from existing Shuttle facilities with minimal modifications. The P/A module would be a biconic lifting body allowing recovery and re-use. Not only would the P/A module go into orbit, but so would the external tank. Each flight of this vehicle would have the potential to orbit the shell of a fantastic space station. This vehicle was described in greater detail in US Launch Vehicle Projects #2. If you are interested in the high-rez version of this, it and many more are available to all $4 and up patrons at the APR Patreon.
