The Atlas 5’s first stage was stacked on top of a mobile platform inside the Vertical Integration Facility at Cape Canaveral’s Complex 41 launch pad early last week. It was to be followed by the hoisting of the Atlas 5’s Centaur upper stage and a single strap-on solid rocket booster.

The change will allow the Centaur upper stage to make a controlled de-orbit and re-entry after it releases the SBIRS GEO Flight 4 satellite, a measure to prevent the flight from adding to space debris in Earth orbit.
Does anyone have the patch artwork seen on the PLF? (I saw it also on the banner in the delivery imagery.)

Is the eagle carrying a rocket in its talons?
Looking good for Thursday’s #AtlasV launch from the Cape. Pgo of 80%, cumulus clouds. #SBIRS
Launch day overall probability of violating weather constraints: 20%Primary concern(s): Cumulus Clouds24-hour delay overall probability of violating weather constraints: 20%Primary concern(s): Cumulus Clouds
