24" x 36"
A representation of all United States moon missions. The first starts in the top-right corner and circles clockwise. Thin lines are orbital missions, thick lines are lander missions, and thick lines with dots on the end are manned lander missions. White lines are failed missions and black lines are successful missions.
You can see there were a lot of failures at the beginning, but with continuous attempts, they were consistently successful. The white line pointing at the 8 o'clock position is Apollo 13.
