This discovery is from JP Skipper and his equally amazing site Mars Anomaly Research. I have followed his site for as long as I have this one and have the utmost respect for his work and tenacity. The image itself has been taken from NASA’s Mars Rover imagery and has not been tampered with by Skipper simply enlarged in the second shot. I suggest visiting his website for the image reference number.
Do aliens also charge 5 cent for plastic bags these days?
