Latest photographs from the rover were examined by Italian imaging expert Elizabeth Bonora who said that the size of such object is somehow hard to measure. However, using the camera’s resolution, she estimates that the object measures between 2-3 centimeters and locates 8- meters from the Curiosity. She called it as a flower on Mars.
Recently, the rover spotted an earlier object which was then discovered to be just a plastic detached from the vehicle onto the planet’s sand. But Bonora claims that she is unsure whether the new object found is part of the rover or not since it is too distant to be clearly identified.
Moreover, the image specialist suggests that the object might be an ice with the composition of a metal. Possibly, it could also be a mineral or a fragment from a meteorite.
On the other hand NASA is still not able to provide comments on the said object following the misinterpretation of the discovery of earlier organics on the red planet.
