On the night of Sept.6, NASA is launching its Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft from the Wallops Island launch facility in Virginia. The colored portions of the map above show areas from which the launch will be visible. Orbital Sciences has a very detailed article on their website showing where and when to look for the rocket in the sky from many locations on the East Coast. http://www.orbital.com/NewsInfo/Missi...
For folks in the Bay Area, NASA Ames Research Center, where LADEE was built, is hosting an outdoor launch party from 5-9 p.m. PDT with giant viewing screens, booths with science displays and food trucks. Ames hosted a similar event last year for the Curiosity rover landing (pictured above). Although the event is free, parking and attendance is limited so you have to register online at: https://amesladee.eventbrite.com/. For more information on the event go here.
The launch will also be broadcast live on NASATV. If your cable or satellite TV provider doesn't carry NASATV, there is an HD streaming feed at: http://www.ustream.tv/nasahdtv
