Visibility Map for Antares Launch
Depending on where you are along the eastern seaboard of the U.S., you might be able to see the flight of the Antares rocket. The downloadable map below shows the projected degrees above the horizon (how high to look) and the path the rocket will fly so that you might be able to glimpse the Antares test flight.
The best chance to see the flight extends from about Cape May, NJ southward through the Outer Banks of North Carolina. Also, if you happen to be in Bermuda, you will likely have a clear view of Antares as it rockets by. Larger map at Orbital Sciences
