This is Antares, a commercial rocket assembled by Orbital Sciences to deliver the unmanned cargo capsule Cygnus to the International Space Station for NASA:
Powered by two liquid fueled Soviet NK-33 engines refurbished by Aerojet and mounted into a Ukrainian-built first stage topped by a US ATK solid-fuel second stage booster, Antares A-ONE, the first test flight, would launch into orbit the Cygnus Mass Simulator to prove to NASA the rocket’s viability for launching payloads to the ISS.
Last week I was one of twenty-five NASASocial participants invited to come see the Antares rocket’s first launch from NASA’s Wallops Flight Facility, and given the same access to prelaunch and launch events as members of the media. The trip would include tours of Wallops and the launch pad, press conferences with NASA and Orbital execs, and the launch of the rocket itself. Between events I would stay on nearby Chincoteague Island and sample some of its off-season delights.
It would be my first NASA Social event since Juno in 2011.
