There are few KSP challenges that have intrigued me more than the Elcano challenge. I've known of it for years, but until recently assumed it would just be a boring slog that takes no skill whatsoever, just hold down W until you make it around the planet. However, upon inspecting it further, I then realized how much more there is to it. It takes fortitude to sit through the boring stretches of driving, engineering prowice to design the optimal rover, and keen driving skills to minimize your risk
