NASA TV will stream the launch on its website.
This week, Northrop Grumman's Antares rocket will launch the Cygnus cargo spacecraft to the International Space Station.
Cloudy weather and rain pushed back until Friday the planned launch of a U.S. cargo ship loaded with supplies for astronauts living at the International Space Station, NASA said Thursday.
The rocket was originally scheduled to launch Thursday morning but the poor weather forecast caused NASA to reschedule it for Friday morning.
Weather permitting, the rocket launch will be visible along the East Coast. NASA had originally planned to launch the rocket 24 hours earlier, but had been forced to push it back as a result of unfavorable weather conditions."Today's Wallops range forecast for November 15 assessed weather conditions at 90-percent unfavorable for a launch, with the main concerns being thick clouds, disturbed weather and low cloud ceilings", said Northrop Grumman, in a blog post on Wednesday. "The forecast for a launch Saturday is significantly improved with a less than five percent chance of weather conditions preventing a launch".
The Cygnus cargo ship is carrying about 7,400 pounds (3,356 kilograms) of new experiments, food and other supplies for the three-person Expedition 57 crew on the International Space Station, NASA officials said.
The delay to 4.01am (0901 GMT) on November 17 from Wallops Island, Virginia marks the second time launch managers have postponed the mission from its initial flight plan of yesterday.
An unmanned Russian Progress supply ship is also scheduled to launch from the Baikonur Cosmodrome in Kazakhstan at 1814GMT today.
Antares and Cygnus aren't the only things launching to the space station this week. That mission will arrive at the station on Sunday (Nov. 18), one day ahead of Cygnus, NASA officials said.
