I found out that Mars is referred to as the Red Planet because of the reddish iron oxide on it's surface.
Really? I had no idea? I find Mars very interesting. Would you visit if you had the opportunity? 
I don't know - Mars has become cold, dry, and pretty much uninhabitable in modern times.  I'm kinda afraid of leaving Earth anyway though - LOL! 
Haha, I feel more adventurous. If Elon Musk would take me there, I'd totally go! Although I maybe not on the first manned mission! :)
Well with his net worth of around $20.9 billion, he'd probably be able to provide a pretty nice trip to Mars!!
