Rocket Lab is poised to broaden its footprint in the space-launch arena. The company has just completed the final qualification tests on the innovative fairing that will crown its newest rocket, the partially reusable Neutron, which is slated to make its inaugural flight early next year.
Dubbed the Hungry Hippo–style fairing, this design opens and closes like a clamshell (reminiscent of the jaws on the Hungry Hungry Hippos game) and represents a fresh approach to reusability in launch systems. While Electron, Rocket Lab’s smaller, largely expendable workhorse, has already gained traction in the small-launch sector, Neutron is built to compete with SpaceX’s heftier Falcon 9—the lone orbital launcher with a proven track record of reusability.
With the qualification phase finished, Neutron’s fairing segment has been shipped to the Mid-Atlantic Regional Spaceport in Virginia, where it will be integrated with the rocket before the first flight.
“A rocket like Neutron has never been built before, and we’re pursuing it at a pace and at a price point that will inject the innovation and competition our industry needs today,” said Shaun D’Mello, Rocket Lab’s Vice President for Neutron, in a December 8 press release.
The company describes Neutron as the world’s largest carbon- composite launch vehicle, and notes that the fairing underwent extensive testing before receiving clearance for flight.
Hungry Hippo is on the move. With qualification and acceptance testing complete, Neutron’s fixed reusable fairing and upper module are en route to LC-3.
Before departure from Rocket Lab’s California test facility, the fairing endured a demanding 275,000 pounds of external force to simulate launch pressures, rapid cycling of the clamshell mechanism to verify faster-than-necessary operation, software integration, and load forces exceeding 125% of the design requirements.
As the fairing becomes part of Neutron’s first stage, the company will conduct a sequence of prelaunch tests, including a static hot-fire of the nine Archimedes engines that power the reusable booster. Neutron stands at about 141 feet (43 meters) tall with a 23-foot (7 m) diameter and is expected to deliver up to 28,700 pounds (13,000 kilograms) of payload to low Earth orbit.
