The first ever Astronaut - Rover (ASRO) Interaction Field Test was conducted successfully on February 22-27, 1999, in Silver Lake, Mojave Desert, California in a representative surface terrain. This test was a joint effort between the NASA Ames Research Center, Moffett Field, California and the NASA Johnson Space Center, Houston, Texas to investigate the interaction between humans and robotic rovers for potential future planetary surface exploration. As prototype advanced planetary surface space suit and rover technologies are being developed for human planetary surface exploration, it is desirable to better understand the interaction and potential benefits of an Extravehiclar Activity (EVA) crewmember interacting with a robotic rover. This interaction between an EVA astronaut and a robotic rover is seen as complementary and can greatly enhance the productivity and safety of surface excursions.

In applications that require space-suited crewmembers to traverse rough terrain, boot fit and mobility are of critical importance to the crewmember's overall performance capabilities. Current extravehicular activity (EVA) boot designs were developed for micro-gravity applications, and as such, incorporate only minimal mobility features. Recently three advanced space suit boot designs were evaluated at the National Aeronautics and Space Administration Johnson Space Center (NASA/JSC). The three designs included: 1) a modified Space Shuttle suit (Extravehicular Mobility Unit or EMU) boot, 2) the Modified Experiment Boot designed and fabricated by RD & PE Zvezda JSC, and 3) a boot designed and fabricated by the David Clark Company. Descriptions of each configuration and rationale for each boot design are presented.
