This structure served as a prototype component for the suspension mounting system of the vehicle's chassis. NASA fabricated this part and then shipped it to Racefab, located in Rusk, Texas, where the rovers were collaboratively designed and manufactured. Each rover incorporates six of these components, based on this initial prototype. According to Racefab, no additional copies of this component exist.
The NASA SEV (Space Exploration Vehicle), aka the "Chariot", or the MMSEV (Multi-Mission Space Exploration Vehicle), is an advanced rover designed to facilitate crewed missions on the surface of extraterrestrial bodies such as the Moon and Mars. Developed as part of NASA's Constellation program, the SEV is an evolution of the original Lunar Electric Rover (LER) concept, with a focus on enhancing mobility, versatility, and human habitability.
The rovers' chassis were constructed from 4130 chromoly steel, an alloy composed of chromium and molybdenum. This material is recognized for its high strength, wear resistance, toughness, and low thermal conductivity. However, these properties also make it challenging to machine.
Once assembled, the vehicles were treated with a powder coating process. Initially, they were coated with a metallic silver layer, followed by a layer of robot gold. Lastly, a translucent finish was applied for an extra touch of aesthetics and protection.
