The photos show Mars at night in visible and ultraviolet light.
The Mars rover Curiosity, also known as the Science Laboratory, will launch in late 2011 and land on the Red Planet in August 2012.
The nuclear-powered mobile science laboratory Curiosity will roll across the surface of Mars for years, searching for the conditions that may have once made Mars an abode of life.
NASA's Spirit rover landed nine years ago today, and its twin Opportunity followed three weeks later.
The bright object Curiosity spotted while scooping soil over the weekend is a piece of itself, scientists say.
