Space cadets! It's twofer night out under the stars this evening. The International Space Station, with the shuttle Discovery tied up at the dock, will fly over the eastern U.S. about dinnertime. Look for a bright, starlike object climbing out of the western sky at 6:33 p.m. The pair will fly about halfway up the southwestern sky, well above bright Jupiter by 6:36, before heading off to the southeast. Women are commanding the station and Discovery. In all, 10 people are on board.
