Cygnus Launch Scrubbed Till Friday

Cygnus Launch Attempt Scrubbed Due to Weather

For the latest Orbital ATK mission information visit the NASA Orbital blog here…

Because of thick clouds with freezing temperatures and precipitation that violated the weather rules for launching, Orbital ATK and United Launch Alliance have postponed the planned launch of the Atlas V rocket carrying the Cygnus spacecraft. It is Orbital ATK’s fourth commercial resupply services mission to the International Space Station.

The next 30-minute launch window opens Friday, Dec. 4, at 5:33:11 p.m. EST. The chance of favorable weather for the next launch is 30 percent. NASA Television coverage will begin at 4:30 p.m. and can be seen online at

A launch Friday would result in a rendezvous at the station and grapple and berthing of Cygnus on Monday, Dec. 7.

Cygnus is loaded with more than 7,000 pounds of supplies and science and research investigations. Science payloads aboard Cygnus will offer a new life science facility that will support studies on cell cultures, bacteria and other microorganisms; a microsatellite deployer and the first microsatellite that will be deployed from the space station; and experiments that will study the behavior of gases and liquids, clarify the thermo-physical properties of molten steel, and evaluate flame-resistant textiles.
