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. ...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.

The second week supported evaluation of the Science, Crew, Operations, and Utility Testbed (SCOUT) prototype rover and its sub-systems. Throughout the duration of the field test, the Communications, Avionics, and Infomatics pack (CAI-pack) was tested. ...The recharge capability allowed the simulated EVA test duration to be doubled, facilitating SCOUT proto-type rover testing. This paper summarizes Desert RATS 2005 test hardware, detailed test objectives, test operations and test results.
