Here is a video of a public presentation by Prof. Jim Bell of Arizona State Univ. on planetary and deep space exploration. Lots of great pictures.
In this talk Professor Bell will review some of the recent highlights from Mars surface missions (especially the continuing adventures of the Opportunity and Curiosity rovers), discuss the kinds of up-close contact science measurements that can be done from such robotic vehicles, and talk about how the lessons learned from these missions can influence future Mars, asteroid, and comet rovers and landers.
This video describes the areas within some craters at the lunar south polar region that sunlight never reaches. The Lunar Reconnaissance Orbiter, however, uses a laser altimeter system to measure the topology of those dark places.
