Delta IV Heavy rocket launch delayed to 2019
The United Launch Alliance once again postponed a Delta IV Heavy rocket launch at Vandenberg Air Force Base.
Officials said it will now happen no earlier than Sunday, January 6.
The rocket will be carrying the NROL-71 mission for the National Reconnaissance Office.
Crews have had to cancel four launch attempts due to technical issues or high winds.
The rocket was first scheduled to take off at the beginning of December.
