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 the show works, but there's

going to be a quiz at the end, so let's go through it again. So you go online to Twitter or Facebook,

use the hashtag Ask a Space Man, send some questions, and then some time in the future,

could be a week from now, could be a month from now, could be a year

from now, at some point I'll get to your question and I'll answer it on this show. Yeah, you can

also email me at Ask aSpaceman at gmail.com. You can also go to Ask aSpaceman.com and

there you'll find the show notes, you can put comments,

you can ask your questions there. So many ways to ask a question so little time. We have one

simple goal with this show, complete knowledge of time and space. It's a modest goal, to be honest.

But, you know, let's do it anyway, because even small goals are worthwhile, right?

They give us a feeling of accomplishment.

comfortable transporting that in my bag and risk losing it and all that stuff. So I've got a cheaper

microphone, so the sound quality isn't as good.

I apologize for that. Also, it's a little bit loud in my little hotel room. I'm right at the

top floor. So right above me is the roof and like birds and stuff, you know, scurry around.

I guess birds don't really scurry. Like squirrels or whatever,

there's something scurrying on the roof here and making some noise. There's scooters outside
