Tuesday's scrubbed launch of NASA’s Orbiting Carbon Observatory-2 (OCO-2) from Vandenberg Air Force Base has been rescheduled for Wednesday July 2.
The launch was scrubbed because of a failure in the launch pad water flow system. The "hold" command was called out over the radio with T-46 seconds to launch.
OCO-2 is NASA’s first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth’s climate.
OCO-2 is being carried into space on a Delta II rocket.
