Space cadets! Marylanders have two chances this weekend to see the International Space Station, if the clouds part. Tonight, the ISS will rise above the northwest horizon at 5:59 p.m. as it flies high over the Great Lakes. Looking like a bright, moving star, it will climb more than halfway up the sky above the northeast horizon by 6:02 p.m. before slipping off to the southeast. If you miss it, try again Saturday. Watch for the ISS in the west northwest at 6:20 p.m., climbing toward the southeast at 6:23.
