Delta IV Heavy rocket launch: Where to watch from Sebastian, Vero Beach, Fort Pierce
Editor's note: FLORIDA TODAY's Space Team was at Cape Canaveral covering the final launch for ULA's Delta IV Heavy rocket when ULA called a scrub at 2:47 p.m. EDT Thursday, March 28. Next attempt is TBD. Here's a link to the Space Team's live coverage blog, which has updates.
Original story:
The final launch for United Launch Alliance's powerful rocket − Delta IV Heavy − is one you won't want to miss. When it launches.
At 2:47 p.m. EDT Thursday, March 28, ULA called a scrub. Previously, it was scheduled at 2:45 p.m. EDT, 1:40 p.m. EDT and 2:03 p.m. EDT. Next attempt is TBD. The Delta IV Heavy rocket, which had been dubbed by ULA as "the most metal of rockets," will deliver NROL-70, a National Reconnaissance Office mission, to space from Space Launch Complex-37 at Cape Canaveral Space Force Station. The mission marks the 389th and last flight of the Delta program, which dates back to 1960. ULA is replacing the retiring rocket with the next-generation Vulcan, which logged a successful maiden flight in January from Cape Canaveral.
Weather permitting and with its eastern trajectory, the Delta IV Heavy rocket launch should be visible from parts of the Treasure Coast when it lifts off.
Here's what we know about the very powerful rocket and best places to watch the launch.
What is Delta Heavy?
Delta Heavy refers to United Launch Alliance's Delta IV Heavy rocket. The ULA rocket made history for its transportation of the NASA Parker Solar Probe in 2018 and the first orbital test flight of the Orion crew capsule in 2014.
It was following the success of this flight that NASA’s Orion crew capsule flew on NASA’s Space Launch System (SLS) rocket, successfully demonstrating an uncrewed mission around the moon in 2022. ULA assisted in this flight as well, as the organization designed the upper stage of the SLS rocket.
The Orion spacecraft is set to take Artemis II astronauts around the Moon in late 2025.
How big is Delta IV Heavy rocket? What’s the size and power of ULA Delta IV Heavy rocket?
The Delta IV Heavy rocket has three Delta IV core stages together. According to the ULA website, each rocket engine produces up to 702,000 lbs. of thrust. With this performance, one can see why ULA dubbed it "the most metal."
These engines are not small either. Just one engine weighs around 14,876 pounds and is 204 inches (17 feet) in length.
Powered by liquid hydrogen and liquid oxygen, the Delta IV Heavy appears to set itself on fire just before liftoff as buoyant hydrogen gas, which is used to cool down the rocket before launch, ignites and burns off. The fiery start may look frightening, yet it's part of the process.

Why is United Launch Alliance's Delta IV Heavy rocket being retired?
Vulcan Centaur, ULA’s newest rocket, had a successful test flight in January of 2024. The Vulcan will replace the Delta family of rockets.
The Vulcan Centaur rocket is less expensive and ULA says it will allow for more flexibility in power, giving the option to add on 2, 4, or 6 solid rocket boosters. FLORIDA TODAY reported ULA is currently testing methods and aiming for reusability in the future, which will lower costs further.

TBD: ULA Delta IV Heavy final launch
The Delta IV Heavy rocket will lift off from Cape Canaveral, Florida, with a classified payload on the NROL-70 national security mission, conducted in tandem with the National Reconnaissance Office and the Space Force’s Space Systems Command. The massive rocket launches the NRO's heaviest satellites. The missions that Delta IV Heavy carried were not all related to science; many were for navigation and U.S. security. Delta IV transported mostly NRO, US Air Force, and US Space Force payloads, getting them safely to their orbit or destination.
The Delta IV Heavy made its debut during a December 2004 demonstration flight from Launch Complex 37.
Mission: United Launch Alliance's last Delta IV Heavy triple-core rocket will launch on the NROL-70 national security mission.

Where can I see a Florida rocket launch in Indian River County, St. Lucie County and Martin County?
Watching a rocket launch or waiting for that launch window while at the beach is so Florida.
