To All Orbital Employees:
Next week, we are scheduled to carry out the first flight of our new Antares space launch vehicle from Wallops Island, Virginia. The current launch date for the test flight is April 17, with a targeted launch time of 5:00 p.m. (EDT). The available window extends until 8:00 p.m., if necessary, to accommodate any pre-launch holds in the countdown that may arise.
The Antares launch will be webcast over NASA.gov and broadcast on NASA TV beginning at 4:00 p.m. (EDT). A NASA host, Kyle Herring, and our own John Steinmeyer of LSG will provide commentary for the broadcast.

NASA has designated the Wallops Visitor’s Center and Assateague Beach as the public viewing sites. Live audio commentary will be provided at the Visitor’s Center location. In addition, in the local Wallops area, WCTG-FM 96.5 will be broadcasting live mission updates. Here is the Wallops information on public viewing: http://www.nasa.gov/centers/wallops/missions/launchviewing.html
For an overview of the mission, the attached Antares A-ONE mission overview PDF file provides information about the timing and sequence of the flight milestones. WD3Q: I will try and provide this to the AMSAT website)
The link to the NASA TV broadcast/webcast will be updated on launch day, but this is the address to access the broadcast: http://www.nasa.gov/multimedia/nasatv/index.html
