Wake up in the wee hours of the morning on the East Coast, and you might get a chance to watch a rocket launch more than three tons of cargo for the International Space Station. Set for a 4:39 ET liftoff from NASA’s facility on Wallops Island, West Virginia, if the weather holds, this will be Orbital ATK’s ninth cargo delivery to the ISS. The Antares launch, which is the company’s first since November, was initially scheduled for today, but was ultimately pushed back in favor of inspections and better weather.
