We have a great chat with Earl Swift about NASA's lunar rovers and his new book Across the Airless Wilds. It's a fascinating dive into the last three moon landings and what could be regarded as the pinnacle of human exploration. Earl recounts his time with astronauts Charlie Duke and Dave Scott, and Laszlo Kestay from the United States Geological Survey, and gives us some incredible insights into the the design process of the lunar rovers and their place in the history of exploration.
