You know what time it is. It's time for Ask a Space Man. I'm your host Paul Sutter. You've got questions and I've got answers. You know how this show works, but let me shape it up for you one more time. You go online to Twitter or Facebook, use the hashtag Ask a Spaceman. If you don't

but, you know, there's some, there's some heavier topics. There's some lighter topics. You know,
