Join Ars in watching the second attempted Antares rocket launch, 5pm EDT (Updated)

As we mentioned yesterday this week, today will mark Orbital Science's first second attempt to send its Antares rocket into space. Antares' originally scheduled launch, set for April 17, was canceled just minutes before take off. But today (Saturday, April 20, 2013), Orbital Science will make a second attempt to get its rocket off the ground. Meant to provide an alternative route to deliver supplies to the International Space Station, the Antares is ready for liftoff at NASA's Wallops facility on the east coast of Virginia.

You can watch the events live on NASA TV. To save you the hassle of finding NASA TV, we've embedded the livestream below—coverage will start at 4pm Eastern. Orbital Sciences has a lot of experience in the rocketry business, so we're crossing our fingers that its first liftoff with the new hardware will go off without a hitch.
