Scarecrow: Curiosity’s Earthbound Brother Several rovers were in action at the JPL Open House that took place in Pasadena, CA this past October. “Scarecrow”, the earthbound surrogate of Mars Rover Curiosity, was on display and put through its paces for attendees to watch. Named Scarecrow because “it doesn’t have a brain”, this rover is not equipped with all the instruments that Curiosity has. This lack of extra weight gives Scarecrow the equivalent weight of Curiosity, with all its instruments, in the lower gravity of Mars.
