The Antares OA-5 will launch from the Wallops Flight Facility this Sunday and should be widely visible up and down the East Coast. It will launch no earlier than 8:03 PM. Watch NASA TV for real time updates. I have dusted off the Wallops app and will be watching. The app shows Wallop's location from where ever you are located.Orbital has been good enough to highlight the visibility from various locations here. The summary for the DC area:Antares will reach 5 degrees about 1 minute and 45 seconds after launch.It will reach a maximum elevation of about 13 degrees (your fist at the end of your outstretched arm is about 10 degrees mas o menos).The solid motor on the 2nd stage will be the most visible and will ignite at L+4 minutes and 23 seconds.
