Awaiting launch of Discovery from Kennedy Space Center this afternoon. Weather is clear right now though one maneuvering vernier heater is causing problems. They think they have the heater fixed so it looks like we are on track for the 3:49PM EDT launch.
Meanwhile an asteroid named 2004 XP14 is supposed to give our planet a fly-by this weekend. This asteroid appears to be a half-mile in size and will pass at a distance of 269,000 miles. The mean distance from the Earth to the Moon is 238,857 miles. Viewing times in North America to see this whizzing dot will start Sunday night with best viewing early Monday morning in North America. Its track should cross the constellations of Andromeda, Perseus and Cassiopeia.
So it looks like we will have a jammed pack celestial Fourth of July. May it be a safe one for all.
Update: NASA has scrubbed the launch for today due to thunderstorms. So the proposed launch window is now for tommorow and 22 minutes earlier than today to accomodate shifts in the ISS's orbit.
