The story I heard from a NASA guy was the the original wheels had the JPL logo but NASA put the nix on that, so Morse code was the next best thing.
I was at a high school robotics competition where NASA had a replica of Curiosity. It’s pretty impressive.
On May 19th, 2005, NASA's Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera mosaic was taken around 6:07 in the evening of the rover's 489th martian day, or sol. Spirit was commanded to stay awake briefly after sending that sol's data to the Mars Odyssey orbiter just before sunset. The image is a false color composite, showing the sky similar to what a human would see, but with the colors slightly exaggerated. (NASA/JPL/Texas A&M/Cornell)
