Check this out, the Air Force successfully fired off the largest ever rocket launch the West Coast has ever seen yesterday when a Delta IV Heavy rocket lofted a supposedly very large spy satellite for the National Reconnaissance Office into a low Earth orbit.
The Delta IV Heavy stands 235 feet tall and its three RS-68 liquid oxygen-fueled rocket boosters kick out 2 million pounds of thrust. The rocket can carry up to a 49,000 pound payload into a low Earth orbit.
