The calibration target for the Mars Hand Lens Imager (MAHLI) instrument also includes a “Joe the Martian” character, color references, a metric bar graphic, and a stair-step pattern for depth calibration. […]

The Joe the Martian character appeared regularly in a children’s science periodical, “Red Planet Connection,” when Edgett directed the Mars outreach program at Arizona State University, Tempe, in the 1990s.
