| Curiosity's tire tracks on Mars (NASA photo) |
When the Curiosity
rover drives around Mars, it reportedly will leave tracks of squares and rectangles on the
red planet's surface. Officials at the Jet Propulsion Laboratory, which built
the rover, say the patterns serve as odometer markers. But, reports Newsline, those small and large blocks look a lot like dots and dashes and
indeed, spell out "JPL" in Morse code! However, photos of Curiosity's first "test drive" don't seem to show anything except tire tracks.
