A hydrogen-fueled predominant engine and 4 stable rocket boosters mixed to propel a United Launch Alliance Delta Four rocket off its launch pad at Cape Canaveral on March 15, efficiently sending a U.S. Air Pressure communications satellite tv for pc into orbit.
The Aerojet Rocketdyne RS-68A predominant engine and the 4 solid-fueled boosters, constructed by Northrop Grumman, generated 1.eight million kilos of thrust to drive the 218-foot-tall (66-meter) Delta Four rocket off the launch pad at eight:26 p.m. EDT Friday (0026 GMT Saturday).
These images present the Delta Four’s night liftoff from Cape Canaveral, which was delayed 90 minutes for engineers to handle a number of technical considerations. It was the 39th flight of a Delta Four rocket since 2002, and the next-to-last launch of the fundamental model of the Delta Four with a single first stage core.
