paul brinkman, ipi -- upi and our next reporter, paul? >> yeah, thanks. i'm really thinking about the astronauts in space now. and you know, four people trying to sleep after launching on a rocket. and flying around the earth on a new spacecraft. my understanding is the flight time tonight apparently was extended partly for their sleep time. and we've heard how important it is that they get proper sleep. but i'm thinking that must be kind of a challenge. so i guess, kathy, can you talk about how well astronauts sleep in space and is a it a really peaceful ride aboard dragon now? is it cruising in orbit stlor a lights-out rule or a no-talking rule? yeah. thanks. >> well, you know, they do have little curtain that is they cover the windows and they -- curtains that they cover the windows and they get out of the suits and lay down. you have to realize, you're in zero g, too, right? so you're in a little bit different position. you know, these are experienced crew members and they know that they've got to get their rest and work through them. and so the other
