A back view of the Lunar Electric Rover (LER) during the Desert Research and Technology Studies (RATS) remote field test at Black Point Lava Flow, Arizona in 2008. Two Mark III spacesuits are visibly mounted on the LER suit port.

Mike Miller demonstrates one of the backpacks his team designed and built for the Desert Research and Technology Studies project's upcoming field test in Arizona. Miller led the team that developed the backpacks. The backpacks are equipped with GPS antennas, communications components and cameras. They are meant to show researchers what an astronaut might need to explore an alien world and give designers a look at the hardships the equipment could encounter. Photo credit: NASA/Frank Michaux
