Dubbed the ultimate symbol of power in the realm of rockets, the United Launch Alliance’s colossal Delta IV Heavy ignited the skies with a spectacular hydrogen inferno at the launch pad. This dramatic scene unfolded as ferocious flames engulfed and charred the rocket’s orange boosters, moments before its ascent.
Beyond the striking visuals reminiscent of a heavy-metal concert, Rob Long harbors a deep affection for this soon-to-be-retired behemoth of space exploration. Having dedicated over three years as the mission manager for the National Reconnaissance Office, Long played a pivotal role in the preparation for the agency’s inaugural Delta IV Heavy launch, NROL-26, in January 2009 from Cape Canaveral. This rocket holds a special place in his heart, as it does for the myriad of employees who have contributed to the program over the past two decades along the Space Coast.
Cape Canaveral has been buzzing with anticipation for the upcoming rocket launches scheduled by SpaceX and NASA in Florida, marking an exciting era in space exploration.
Reflecting on his journey, Long, now the president and CEO of Space Florida, reminisced about the invaluable learning experience of integrating a satellite onto a launch vehicle. This hands-on experience provided him with a comprehensive understanding of the entire process.
As we approach the end of an era in American spaceflight, the 16th and final Delta IV Heavy rocket is poised for liftoff at 1:40 p.m. Thursday from Launch Complex 37 at Cape Canaveral Space Force Station. However, United Launch Alliance officials have indicated only a 30% chance of favorable weather conditions for the launch.
This mission signifies the conclusion of the Delta program’s storied history, which began in 1960. In its stead, ULA is introducing the next-generation Vulcan rocket, celebrated for its successful maiden voyage in January from the Cape. The Vulcan’s adaptable design allows for configurations with varying numbers of solid-rocket boosters to support a diverse range of orbital missions.
Reflecting on the transition, Long expressed a mix of nostalgia and excitement for the future. “We’re embracing reusability and innovative approaches to space exploration. While it’s nostalgic to bid farewell to the Delta IV Heavy, it’s also a reminder of the industry’s forward momentum,” he stated.
Tune in to floridatoday.com/space on Thursday for live coverage and updates on the Delta IV Heavy’s final mission, starting approximately two hours before takeoff. This historic launch will carry a classified payload for the NROL-70 national security mission, in collaboration with the National Reconnaissance Office and the Space Force’s Space Systems Command, showcasing the rocket’s capability to launch the NRO’s heaviest satellites.
ULA CEO Tory Bruno shared his admiration for the Delta IV Heavy, describing it as a “beautiful rocket” that has embarked on remarkable missions. “It’s the epitome of metal, igniting itself before venturing into space. I absolutely love it, and its retirement will be bittersweet,” Bruno remarked.
The Delta IV Heavy made its debut in December 2004 with a demonstration flight from Launch Complex 37, marking it as the most powerful rocket launched from Cape Canaveral at the time, second only to the Saturn V and space shuttles. Its first mission carrying a payload took place in November 2007, launching a U.S. Air Force satellite for early warning of intercontinental ballistic missile launches. Long’s involvement in the NROL-26 mission in January 2009 marked the rocket’s second mission and third overall flight.
The Delta family of rockets, including the smaller Delta II, has played a crucial role in delivering a wide array of payloads over the past six decades. These missions have supported military, government, and commercial endeavors, including weather and communications satellites, robotic probes for exploration, eight Mars rovers, and one telescope.
As we anticipate the final launch of the Delta IV Heavy, it’s clear that this momentous event will be a significant milestone in the annals of space exploration, celebrated by enthusiasts and professionals alike.
