The Delta IV rocket will take off as early as Dec. 30, after getting scrubbed for the fourth time out of Vandenberg Air Force Base Wednesday.
The United Launch Alliance announced the new launch date on Twitter Thursday morning.
The #DeltaIV #NROL71 was scrubbed on Dec. 19 due to elevated hydrogen levels within the port booster engine section. The team is currently reviewing all data and set the next launch attempt no earlier than Dec. 30, 2018. pic.twitter.com/s1gSEeZBF9

The space launch provider said the launch was cancelled 10 minutes before takeoff on Wednesday because of elevated hydrogen levels within the port booster engine section.
Originally ULA said they would attempt the launch in 24 hours before pushing the launch date back at least 10 days.
This was the fourth attempt at launching the rocket.
The launch was scrubbed Tuesday night because of high ground winds. It was delayed twice before, on Dec.7 and Dec. 8 because of technical issues.
When the rocket takes off it will deliver a satellite for the National Reconnaissance Office into orbit.
