Orbital Sciences has been in the space business since 1982 — mostly as a satellite builder and small-payload launcher — but the company introduced a new vertical launch vehicle to the world on April 21 when the Antares successfully launched on a test flight from Wallops, Virginia.
The next step is to launch their Cygnus cargo module on a demonstration flight to the International Space Station sometime around June. If successful, the United States will be the only nation with two robotic space vehicles capable of delivering cargo to orbit.
Ninety minutes later, NASA held a joint press conference with Orbital.
