Phobos and Deimos, Prepare to Say ‘Cheese!’

The insert in this image is a simulation of what the Mars Reconnaissance Orbiter's optical navigation camera images of the Martian moons Phobos and Deimos will look like. The images will not be up-close portraits of the moon like we have from the Viking missions. They will be contextual pictures that will aid navigators in getting the most specific location data, so they know exactly where the Mars Reconnaissance Orbiter spacecraft is before its orbit insertion.
