Today marks the 45th anniversary of Neil Armstrong and Buzz Aldrin landed on the moon. Should we go back? Will we be on Mars anytime soon? What's next? Discuss.
Also, if you've got a bunch of free time, watch "In the Shadow of the Moon". Produced by Ron Howard, all original footage from NASA, news, etc from the moon missions and the only people who talk are the guys who've been there, telling their story. Easily my favourite documentary.
