My DS9 has recently re-discovered astronomy and NASA. We spent hours at a planetarium and observatory during their "starry nights" programming last weekend. I was aware that DS knew a lot about astronomy but it's almost as if the cap was removed from a carbonated beverage. He can't stop talking about his experience and wants to go back this weekend. Then, on Sunday, Dateline NBC had the 40th anniversary of Apollo 13. He was mesmerized.

I am hoping that someone has some fantastic resources. I am considering ordering the complete series of NASA mission dvds from Discovery. Any books, workbooks, or video series anyone can recommend?

Thanks!
