I signed up to give an astronomy talk to Claire's class next month. A lot has happened since I was paying attention (i.e. my scale models stopped following the Apollo era). So, if you have cool links you'd suggest, I can access them using a "smart board" in her class.

I'm thinking I'll focus on Mars, since some of the current rovers there are controlled from a node in StL, e.g.:

Mars Rovers from JPL site:

Any other ideas? I'm wide open.
Last time (my talk on the circulation system) Claire's class chewed through my material pretty fast, and in desperation, I ended up doing a mock appendectomy on Madeline the French orphanage girl.
