Today the private spaceflight company Orbital Sciences is hoping to launch its Antares rocket carrying the first fully functional Cygnus cargo spacecraft, which is set to reach the International Space Station early Sunday morning.
Launch is scheduled for 10:58 am ET from the Mid-Atlantic Regional Spaceport at NASA's Wallops Flight Facility in Virginia. Though this is considered a test mission, the unmanned Cygnus is hauling about 1,300 pounds of real supplies for the ISS.
This is the first U.S. launch to the ISS from Virginia.
For those on the East Coast, here's where to look to view the rocket launch from the ground.
Update: Success! Congratulations to Orbital Sciences and NASA!
