Air Force meteorologists on this Good Friday have released their initial forecast for Tuesday’s launch of a cargo ship to the International Space Station, predicting favorable conditions to fly the Atlas 5 booster on a commercial mission.

A Northrop Grumman Antares rocket rolled out to its launch pad on Virginia’s Eastern Shore early Tuesday, setting the stage for liftoff Saturday on a resupply flight to the International Space Station that will debut an upgraded launcher and Cygnus cargo vehicle capable of hauling heavier payloads into orbit.

Watch the briefing to learn what is aboard the Orbital ATK Cygnus OA-6 resupply freighter launching to the International Space Station on March 22 aboard a United Launch Alliance Atlas-5 rocket.
