I suppose the 15-minute break doesn't exist in outer space. While watching footage of astronauts tune up the Hubble Telescope last night on the news, it occurred to me that these people show up to do work.
It makes sense on a few levels. First, where would they go on a break? It's an ironic little twist that in the vastness of space they could really only float in the corner of their shuttle.
-What are you doing?
-I'm on break.
Plus, with the help of the best communication technology money can buy, they are in constant contact with their employer. That's part of the reason I would be the worst astronaut ever.
Crewmate: Jess, Houston's on the phone for you.
Me: [waving my hands, shaking my head with wide eyes and slowly whispering] I'm not here.
Houston: Um, yeah, we can see you.
Note: I don't think they use phones in space. It'd be cool if they did though. Every time the phone rings a mission specialist shouts out, "I'll get it!" and then doggy paddles over to the rotary.
