OCO-2 Launch Delayed

Today’s launch attempt was scrubbed because of a failure in a Vandenberg Air Force Base Space Launch Complex 2 pad water system. The system provides sound suppression to dampen acoustic waves at liftoff and protects a launch pad flame duct. The countdown was halted at T-46 seconds.

The Orbiting Carbon Observatory-2 (OCO-2) spacecraft is on external power and the Delta II rocket first stage liquid oxygen is being offloaded. Both the spacecraft and rocket are in a safe configuration.

Managers and engineers are assessing the issue to determine the cause of the failure and when they next can attempt to launch OCO-2.
