OCO-2 Launch Scrubbed for Today

OCO-2 Launch Scrubbed for Today

NASA’s launch of the Orbiting Carbon Observatory-2 (OCO-2) spacecraft today (July 1) was scrubbed in the last minute of the countdown due to a launch pad problem.  A new launch date has not been announced.

Shortly after reaching the T-1 minute mark, with everything looking perfect for launch at 05:56:44 EDT, “hold, hold”hold” was called because “we have no water flow.”

Water is used for sound suppression at liftoff and apparently that water system did not function as planned.  The launch had only a 30 second window, meaning there was not enough time to diagnose and fix the problem for a launch today.

There is a launch opportunity tomorrow (July 2), but whether the problem will be fixed in time is unknown.  Check back here for updates as they become available.

OCO-2 is a replacement for the original OCO, which was lost in a launch failure in 2009.
