I keep finding mules in unexpected places. Like the 40-year anniversary of the Apollo moon landing.

Did you know that Apollo 11 Commander Neil Armstrong piloted a mule through the Grand Canyon in March 1964? I didn’t either, until I saw it on the U.S. Geological Survey Web site.  

Armstrong and Buzz Aldrin were trained in astrogeology in order to learn about the geology of potential lunar landing sites and aid in sample collection. This included the creation of artificial impact craters and, apparently, at least one mule trek.
