#AtlasV will use three burns of Centaur over six hours to inject the #SES20 and #SES21 spacecraft into near-circular, near-geosynchronous orbits. This translates to minimal orbit raising by the spacecraft to reach their destination, enabling a more timely activation of services.

Our #AtlasV has arrived at its Cape Canaveral pad for Tuesday's launch of two @SES_Satellites commercial spacecraft that will relay TV channels to more than 100 million homes across America. Launch time is 5:36pmEDT (2136 UTC).

The rollout seems to have been aborted. Atlas made it about halfway to the pad, paused, and began to return to the VIF...

We even tried to help it by making it slightly downhill, (from the camera's perspective, at least).

And yet an hour later, as per my earlier post, ULA tweeted to show it at the pad!

The #AtlasV #SES20 #SES21 artwork is inspired by Vincent van Goghís "The Starry Night." To make the artwork come to life, stare at the animation on the left side for 20 seconds before looking at the night sky of the mission artwork.

ULA is preparing to launch a pair of SES communication satellites atop the Mighty Atlas V in the 531 configuration.

Itís not unusual to see a little water around SLC-41, but itís especially soggy after Hurricane Ian!

Nice summary by @ulalaunch of tomorrow's Atlas AV-099 launch profile, which will deploy two SES sats in a 34500 x 35000 km x 1.9 deg near-GEO following intermediate 163 x 611 km x 28.1 deg and 193 x 35000 km x 26.1 deg coast phases.

This is the first use of an Atlas V to deliver commercial sats directly to GEO. Four military-payload flights have done so, though.
