Orbital Sciences Corporation’s Antares rocket has been cleared for its maiden flight on Wednesday evening. The launch window opens at 5 p.m. EDT/2 p.m. PDT. NASA Television will begin at 4 p.m. EDT/1 p.m. PDT.
The flight from the Mid-Atlantic Regional Spaceport on Wallops Island in Virginia will test the company’s new rocket and also launch a mass simulator that will approximate Orbital’s Cygnus freighter, which is designed to carry cargo to the International Space Station later this year.
Orbital Sciences will be providing updates on Twitter @orbitalsciences and on Facebook at www.facebook.com/OrbitalSciencesCorp. The company will post photos on its Flickr page www.flickr.com/photos/orbitalsciences/.
