As 2016 draws to a close, United Launch Alliance (ULA) is busy making final preparations to launch the EchoStar XIX communications satellite on the Atlas V rocket. Liftoff is scheduled for the beginning of a two-hour launch window at 1:27 p.m. EST (18:27 GMT) Dec. 18.
Originally scheduled to launch on Dec. 16, ULA was forced to delay the mission two days due to a hardware issue discovered during final checkout procedures.
EchoStar XIX will be launching on the 431 variant of the Atlas V, which has a 4-meter payload fairing, 3 supplemental solid rocket motors, and a single-engine Centaur stage. This will mark the 12th mission of the year for the Colorado-based launch provider.
