The most powerful telescope aboard NASA's Mars orbiter has captured a stunning view of Earth and the Moon, showing continent-size detail on the planet and the relative size of its natural satellite.<br/><br/>The image combines two separate exposures taken on November 20 last year by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter.<br/><br/>For presentation, the exposures were processed separately to optimise detail visible on both Earth and the moon.The distance between Earth and the moon is about 30 times the diameter of Earth.
