My six year old son asks: What sort of things does NASA plan to bring back from Mars? Rocks? Water?

What do you need? What technical innovation, feasible in the next 5 years, would be most beneficial to the Mars program? Put another way: what products and research currently being worked on would most reduce the risks and/or costs of the mission?

I hope this isn't too much of a "trolling" question, but I really am curious: why does Philae rely on solar cells instead of nuclear batteries?

How fast is your internet and how do you get it?

I heard "grandaddy longlegs" are very poisonous, but can't bite humans. Is this true?
