Space Cadets! If you missed Thursday's flyover by the International Space Station, you can get make-up credit tonight. The station's course is the same, flying from high over New Orleans to Baltimore and Nova Scotia. Look southwest at 8:39 p.m. Have the kids watch for a bright "star" climbing quickly toward the zenith. It will pass between Saturn and Mars before reaching its highest altitude at 8:42 p.m. Then see it cruise off toward the Big Dipper, disappearing in the northeast at 8:45 p.m.
