Prof. Jim Bell talks about exploring Mars, the Moon, asteroids and more with rovers and landers

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.
