This photo shows two small drawings inscribed inside the front left wheel of the Mars Perseverance rover, pictured here before it was installed on the rover. One figure represents the tracks that the rover leaves as it drives on Mars. The other resembles that same pattern, twisted into the shape of DNA. The symbols represent humanity's fundamental drive to invent the tools necessary for exploration, and serve as a reminder that our space robots are of human origin.

NASA's Jet Propulsion Laboratory in Southern California built and manages operations of the Mars 2020 Perseverance rover for NASA.
