(CNN) — NASA postponed its launch of the Orbiting Carbon Observatory-2.
NASA tweeted out that the countdown stopped at 46 seconds because of a failure in the launch pad water flow.
The rocket was set to measure atmospheric carbon dioxide.
During their last attempt to launch a carbon satellite in 2009, it crashed into Antarctic waters just minutes after takeoff.
Meanwhile, there is no word on when they plan to reschedule the launch.
