As the focus shifts to operations beyond low Earth orbit such as the Deep Space Gateway and eventually Mars transit vehicles, the need for external operations will not decrease, but the remoteness, communications limitations, and implications of an EVA accident will change the approach taken. One factor would be the proposed space exploration vehicle (SEV), currently envisioned as a two-person vehicle capable of supporting EVA via suitports and designed for extended duration sorties. However, the current SEV concepts are spacecraft of a scale comparable in mass to Dragon or Starliner vehicles, and therefore unlikely to be affordable in a cost- and mass-constrained exploration architecture. In addition to a simple mass-based cost estimate, some of the more recognizable features of the current concepts, such as multiple large windows, will further amplify the development and production costs of the system. en_US As an outgrowth of ongoing research into single-person space utility vehicles, the University of Maryland has performed a number of studies of the potential roles of small vehicles to support external operations in microgravity. In this paper, we consider how direct eyes-on'' vision compares to various forms of video in the control of dexterous robotics. Tests to date have demonstrated that direct vision is generally inferior to multiple high-resolution video views, calling into question the need for large and/or multiple windows. dc.language.iso eng en_US dc.publisher 48th International Conference on Environmental Systems en_US dc.subject Stereo Vision dc.subject Teleoperation dc.subject Eyes on dc.subject EVA Assist dc.subject Robotic Manipulation dc.title Concept Evaluation of Minimal In-Space Vehicles in Support of Exploration External Operations en_US dc.type Presentation en_US
