The rover will look not only at the surface of the planet: the rover will look deep under it using a radar penetrating the earth called RIMFAX. Unlike similar instruments aboard Martian orbiters that study the planet from space, RIMFAX will be the first ground-penetrating radar installed on the surface of Mars.
A short video about how the rover was assembled and packed under the head fairing, and another video - how the rocket was moved from the "shipyard" to the launch pad.
