SpaceX called off its latest launch of its Falcon 9 rocket with the Deep Space Climate Observatory on board, just 12 minutes remaining on the countdown as high winds grounded the mission.
SpaceX must launch the observatory by Wednesday, Florida time, or face a delay until 20 February.
It is the second launch attempt in three days. A planned liftoff on Sunday was cancelled due to a radar malfunction and bad weather stopped a second attempt.
