You know, when it comes to other planets it would seem that there’s always someone with too much time willing to come up with a conspiracy theory. The latest involves a rock photographed by the NASA Curiosity Rover in a region on Mars that has been named “Yellow Knife Bay“. A keen UFO enthusiast was trawling through 100’s of NASA Curiosity pictures when he discovered a picture with a rock central frame that does bare a startling resemblance to a rodent of some description. Theories of the nature of the rock ranged from a fossilized mammal to a bizarre NASA experiment to see how long a rat could live on Mars.
Sadly, and much to the chagrin of ufologists, the rock is just…well…a rock. Seeing forms we think we recognise in seemingly mundane objects happens due to a psychological phenomena known as pareidolia. It was proposed by Carl Sagan that human beings are hard wired to see forms we recognise in random patterns. From a survival perspective this is potentially a very useful trait, the thing lurking in the bush that looks like a leopard may actually be a leopard! From the perspective ufologists and those of us with the time to stare up at clouds on spring mornings, it means that we see shapes in seemingly unusual places that we associate with real life objects.
Joy Crisp, a project scientist from NASA’s JPL told reporters yesterday that “Clearly, it [the rock] results from, you know, a lot of things like wind erosion and mechanical abrasion and breakdown chemical weathering of the rocks, as to why they get these weird shapes,”
In an odd but predictable twist to this story “@RealMarsRat” can now be found micro-blogging on twitter.
Curiosity is about to start it’s long journey to the base of Mount Sharp, a martian mountain that reaches 3.4 miles into the Martian Sky. NASA scientists are hoping to find more signs of liquid erosion as they study a region that they hope will be rich in visible sedimentary layers. Curiosity has already found striking evidence for ancient stream beds on Mars and conditions that could have suited microbial life in Mars’ past.
