As the Mars rover Curiosity prepared to take its first soil sample, scientists scoured the photos it took and discovered a shiny object laying on top of the planet's surface. Upon further study NASA scientists believe that it's something that fell off Curiosity, such as a piece of plastic.
After enhancing this image of the first one-half-inch shiny object, NASA determined that it might be debris that fell from the spacecraft during its Mars landing.
Prior to Curiosity's encounter with shiny objects, it examined this rock and hit it with two laser blasts.
"The circular black and white images were taken by ChemCam to look for the pits produced by the laser. The purple circles indicate where the Alpha Particle X-ray Spectrometer trained its view. "
