Delta IV Heavy

We are launching a pretty cool rocket tomorrow night. The 230 ft tall Delta IV Heavy is basically three hydrogen boosters strapped together for a total thrust of nearly 2,000,000 lbs at liftoff. Despite the two million pounds of thrust, the thrust ratio is only 1.2:1 making this heavy pretty slow off the pad. That should give plenty of time to check out the three massive pillars of flame. This will be the most spectacular night launch since Saturn V launched Apollo 17 in 1972.

The massive rocket scheduled for liftoff from Cape Canaveral's Complex 37 at 8:39 p.m. EST. The evening's launch window will extend 122 minutes to 10:41 p.m. EST. You can view the launch here.
