摘要

Launch of the Antares medium-lift rocket this week will open up a new East Coast spaceport within sight of the Washington Monument. If all goes well with the inaugural flight of the Orbital Sciences Corp. commercial cargo carrier, the upgraded sounding-rocket facility on Wallops Island, Va., will send spacecraft to the International Space Station (ISS) and the Moon before the year is out. Down the road, Orbital sees the state-owned facility as the starting point for scientific, military and commercial missions in the Delta Ⅱ class, including polar-orbiting spacecraft. Liftoff of the first Antares on its Commercial Orbital Transportation Services (COTS) test flight is set for 5 p.m. April 17, with an instrumented Cygnus cargo carrier on top. Launch attempts on the following two days also are possible in case of weather or other delays at the new oceanside pad.
