Wonder what the crew of Discovery have been doing since they undocked from the International Space Station and will be doing until they land in a little under 24 hours? Well, a big part of that work is to adjust their sleep schedules. [Heh.] Station sleep/wake cycles don’t match up with when Discovery is to land, so they spend some time getting enough sleep so that, once the time comes to land, that’s about “mid-morning” or so for them.

Am I happy with how STS-114 has gone? Generally, yeah. It’s been a great mission. But I won’t feel good I see two puffs of smoke come out from under the tires on the Orbiter’s landing gear and then see that big ol’ nose come down on the third axle.

Godspeed, Discovery, and we’ll see you soon.
