NASA's Curiosity rover has put the spotlight on Mars. The Red Planet has become the darling of the Milky Way and with good reason. The striking alien landscape features sand dunes, craters and jagged rock formations that give Curiosity plenty of photo opportunities.
Even before Curiosity began exploring Mars, NASA had sent other rovers and orbiters to explore the fourth rock from the sun. We explored the NASA archives to find the 10 most beautiful photographs ever captured of the planet.
