New video captured by the space rover "Curiosity" and released by NASA shows something race across Mars.
Curiousity, the most high-tech interplanetary rover ever built, touched down on the Martian surface earlier this month inside of a giant crater after a tricky landing routine that included a series of braking tricks, a heat shield and a supersonic parachute.
Video sent back to NASA shows the moving object in the distance.
While everyone has their own ideas, we want to know what you think it is. A speck of dirt, a falling star or maybe even a Martian flying around the planet?
