The crew can sleep in shifts which means it would be orbital night all the time! Too many times, I've heard the NASA commentator claim: " is just now crossing the terminator, moving into orbital night." Yes, indeed, that applies to the orbiter being out of direct sunlight -- but it's not a reference to sleep periods or sleep shifts. I've covered too many missions to know that one ain't right. I know the brackets define the terminators for passage into and o ut of direct sunlight. I was just concerned that I might have gotten the definitions backwards. --- Opus-CBCS 1.20.17 * Origin: NSS BBS - Ad Astra!
