.39? Pretty exact are we?
It's the beginning of a short window (somewhere around 5 minutes) when the plane of the International Space Station's will precess about the earth (thanks to the oblateness of the planet) to sync up with the shuttle orbit on Sunday when they perform rendezvous. If they miss the time, it has an associated fuel penalty that comes with performing the necessary yaw steering to correct for the delay, and at about $10,000 per pound of payload to LEO, well, it's preferable to NOT need to have extra fuel...
