Surface to Orbit Tanker Loading & Refueling This is an on-going series. See Mars terraforming image links below. Here two crew members work on the surface completing preparations to load the Titan Reusable surface to orbit tanker. The wheeled vehicle is an autonomous service cart which serves as the transfer point for both the harvested atmospheric gases and LH2 fuel – the service cart contains pressure regulators, pumps, along with the required line purging and venting systems, and holds the twin motorized spools & flexible hose which connects it back to the atmospheric processing plant. Bryce 7 balked at the file size of the set with all vehicles, processing plant, automated cart, and space suited figures and would not render it at the scale I wanted – so after several attempts ending in crashes I settled for this close up at a smaller scale than I would like – but I thought the detail important. I will make another attempt at the entire working site – perhaps omitting the space suited figures and or automated cart and post that in a few days. Model Credit: Space suit is a Google SketchUp 3DS model of the NASA Mk III suit design created by Max Grueter. All other models are my own constructed in Bryce 6.5, and rendered in Bryce 7 Pro. As always thank you for your interest, thoughtful comments, and encouragement.
