A: Hey, guys. We're going to meet a real astronaut. Isn't it exciting?
B: Yeah. I can't wait to see Captain Brown! I'm really curious about his life in space. I have plenty of questions to ask him.

B: Oh, such as what facilities do they have in space to support their daily life?
C: That sounds like a good question. But I'd also like to know about how astronauts sleep. What do they do so as not to float around while they sleep?
