Interesting bit of info about the launch from Florida Today: The Delta 3 has a capacity to launch commercial communications satellites weighing up to 8,400 pounds into a normal 100 x 19,323 nautical mile geosynchronous transfer orbit (GTO). That preliminary orbit is then raised by the satellite's onboard engine to place the spacecraft into circular geostationary orbit 22,300 miles above a specific point above the Equator. However, Orion 3 weighs 9480 pounds at launch, more than a thousand pounds above the Delta 3's nominal performance to GTO. As a result, the Delta 3 will deliver Orion 3 into a lower sub-transfer orbit with an apogee of 13,886 nautical miles, and the spacecraft making up the difference during orbital raising maneuvers in the coming days following launch.
