In late 2024 or early 2025, United Launch Alliance (ULA)’s Vulcan Centaur rocket will fly its first of greater than two dozen U.S. Area Pressure missions allotted underneath a nationwide safety house launch contract.
“It is extremely thrilling,” Mark Peller, Senior Vice President of Vulcan Improvement and Superior Packages at ULA, instructed Area.com lately. “We have stacked the rocket down on the Cape [in Florida] and are going by all the conventional pre-launch processing.”
The Vulcan Centaur rocket will change ULA’s workhorse Atlas V, which has been flying since 2002. ULA selected the BE-4 engine from Blue Origin to energy the newer rocket’s first stage, versus the Russian-made RD-180 utilized by Atlas V.
“As we transition operations from Atlas to Vulcan,” Peller stated, “the group I fashioned to develop Vulcan continues to work although deliberate upgrades to Vulcan to enhance its efficiency, its versatility and meet the evolving calls for of our clients in a aggressive market.”

One in every of Vulcan’s advantages is lower-cost launches, resulting from what ULA calls sensible, modular, autonomous return technology, or SMART for brief. SMART permits for the costliest rocket elements to be recovered post-launch, then refurbished for reuse. “Nearly all of the worth of the rocket is within the again finish that comprises the engines and plenty of different vital programs,” Peller stated.
SMART reuse attracts on a non-propulsive answer to get well the again finish downrange of the launch. “We use an inflatable warmth protect, or ‘aeroshield,’ that we’re co-developing with NASA to assist gradual the engine module because it reenters the environment,” Peller stated. “Within the remaining phases of flight, we deploy parachutes, and it does a gentle splashdown within the ocean.” The inflatable warmth protect protects the again finish, serving as a life raft, till the ULA group recovers it.
Along with private-industry clients, NASA plans to make use of Vulcan, however the Area Pressure’s USSF-106 mission is the subsequent one on the books.
“The Vulcan Centaur launch system brings a wide variety of efficiency capabilities and technological improvements from its baseline configuration,” Col. Doug Pentecost, deputy program govt officer for the Area Pressure’s Assured Entry to Area program, stated in an emailed assertion. “With the launch of Vulcan, now we have accomplished our transition from the Russian engine and now have a single core rocket to ship to our extra demanding orbits.”
The methane-fueled Vulcan has now flown two certification missions, a requirement for finishing up Area Pressure missions. Whereas each missions had been profitable from ULA’s perspective, they weren’t with out their points.
Vulcan’s debut, known as Cert-1, launched on Jan. 8, 2024 from Florida’s Cape Canaveral Area Pressure Station. The rocket carried the Peregrine lunar lander, constructed by Pittsburgh-based firm Astrobotic.
With a manifest that includes a wide range of space-bound deliveries from 20 clients, reminiscent of a NASA laser array, a swarm of tiny robots, a bodily bitcoin and even a hunk of Mt. Everest, Peregrine aimed to make America’s first privately funded moon touchdown.
Vulcan Centaur carried out nicely. However Peregrine got here up quick: Because of a propellant leak from a defective helium strain management valve, the lunar lander by no means made it to the moon; it drifted by house for 10 days, then was guided to a managed destruction in Earth’s environment.
Vulcan’s second certification mission launched on Oct. 4, additionally from Cape Canaveral Area Pressure Station. In distinction with Vulcan’s maiden voyage, this mission had no paying clients.
Whereas launching Sierra Area’s Dream Chaser was the unique plan, the robotic house aircraft wasn’t prepared in time, so Vulcan lifted off with experiments and instrumentation enabling ULA to evaluate the rocket’s efficiency. ULA CEO Tory Bruno clocked the launch’s price ticket within the “excessive tens of thousands and thousands of {dollars}.”
Lower than a minute after liftoff on Oct. 4, an anomaly with one of many strong rocket boosters (SRBs) prompted the rocket to veer barely earlier than the principle engines rapidly corrected course, permitting Vulcan to finish the flight as deliberate. “The car was capable of compensate for it and fly by it,” Peller stated of the SRB anomaly.
“It had a minimal affect on efficiency,” he added. “The car proved to be very strong.”
ULA continues to be investigating what occurred. “We made a whole lot of good progress based mostly on a number of the elements of the motor — the particles from that nozzle that had been really recovered,” Peller stated. “That is offered invaluable bodily proof.”
After the completion of the 2 flights, Vulcan’s remaining levels of certification are underway. “The federal government has all the ultimate information deliverables and are simply doing their due diligence earlier than they full the formal certification course of so we will transfer on and fly SF-106,” Peller stated.
On a world stage, spaceflight continues to alter quickly. 2024 has seen a spread of recent developments, which can alter the course the {industry} takes within the coming years.
In January, for instance, Houston’s Venus Aerospace teamed up with NASA to check a rotating detonation rocket engine (RDRE), which might revolutionize the propulsion capabilities of combustion engines. In Could, India’s nationwide house company, the Indian Area Analysis Group (ISRO), efficiently examined a liquid-fueled rocket engine constructed utilizing additive manufacturing, or 3D printing. And SpaceX continues to advance rocket reusability, lately “catching” its Starship Tremendous Heavy booster with the launch tower’s “chopstick” arms.
As we transfer additional into the 2020s, the spaceflight {industry} has solely develop into extra essential. Scientific, navy, and industrial pursuits all depend on an more and more private-funded launch {industry} to deliver us nearer to the celebs.
