After more than six decades of operational service, 389 flights launched and an impressive 95-percent success rate, the curtain finally fell on the Delta Era at 12:53 p.m. EDT Tuesday as the last triple-barreled Delta IV Heavy—labeled by United Launch Alliance (ULA) as its “Most Metal” of rockets—roared into clear Florida skies, heading into history and the program’s sunset. Pounding Space Launch Complex (SLC)-37B at Cape Canaveral Space Force Station, Fla., with 2.1 million pounds (1 million kilograms) of liftoff thrust, the 235-foot-tall (72-meter) Heavy ferried the National Reconnaissance Office’s highly classified NROL-70 payload on the first leg of its trek up to Geostationary Earth Orbit (GEO).

The second time was the charm for the finale of the Delta family of rockets. Following an issue with a gaseous nitrogen pipeline beyond the control of United Launch Alliance (ULA) that caused the March 28 scrub the second launch attempt on April 9 proved successful.
