NASA and Northrop Grumman have postponed the launch of an Antares rocket carrying fresh supplies for the International Space Station for 24 hours due to bad weather. The launch will now lift off early Saturday, Nov. 17, NASA officials said.
The Antares rocket and its payload, an uncrewed Cygnus cargo ship also built by Northrop Grumman, were originally scheduled to launch to the station today (Nov. 14) from NASA's Wallops Flight Facility on Wallops Island, Virginia, but severe weather from storms along the U.S. East Coast prompted a delay to Friday. That same dismal weather forecast led mission managers to push the launch back another day. Liftoff is now scheduled for Saturday at 4:01 a.m. EST (0901 GMT).

"The teams decided to wait another day for launch after assessing continuing unfavorable weather conditions, including high winds and high seas, forecast for Friday morning," NASA officials said. "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. If it is able to launch Saturday, Cygnus will arrive at the station early Monday (Nov. 19), when it will be captured by astronauts with a robotic arm and berthed at an open port on the orbiting lab.
Antares and Cygnus aren't the only things launching to the space station this week. On Friday, a Russian Soyuz rocket will launch an uncrewed Progress cargo ship, called Progress 71, from Baikonur Cosmodrome in Kazakhstan to deliver nearly 3 tons of food, fuel and supplies to the orbiting lab. That mission will arrive at the station on Sunday (Nov. 18), one day ahead of Cygnus, NASA officials said.
