Atlas V launches Cygnus OA-4

12/6/15 ~ 4:44 p.m.

A United Launch Alliance Atlas V rocket launches the Orbital ATK Cygnus module on its fourth
resupply flight to the ISS, known as OA-4. The mission came as a result of the failed launch of the Antares
rocket in October of 2014 from Wallops Island, Virginia, in which the rocket exploded just after lifting off.

This was also the first mission in 27 straight Atlas V flights to have a scrub (due to weather in this case)
over a 40 month period since August 2012
