Update 8:52 a.m.: The Delta-4 Heavy rocket launch has been rescheduled for Saturday with a launch window opening at 1:51 p.m. The live broadcast will begin at 1:31 p.m.
The launch, which is happening at Cape Canaveral, was cancelled Thursday because of stormy weather.
United Launch Alliance’s impressive Delta-4 Heavy rocket is scheduled to launch today from Cape Canaveral with the national defense surveillance satellite NROL-37.
The launch, scheduled for 1:59 p.m. will be broadcast live on ULA’s website beginning at 1:39 p.m.
The Delta-4 Heavy is the largest of a family of expendable workhorse rockets, using two additional rocket booster cores operating at full thrust during liftoff.
It is the most powerful version of the Delta IV rockets.
A launch was originally scheduled for June 5, but had to be postponed because of a “last minute unspecified payload issue,” according to Universe Today.
The launch of the spy satellite Thursday will be the 32nd Delta 4 mission since the rocket’s inaugural launch in 2002.
