The inaugural flight of Rocket Lab\u2019s reusable, medium-lift Neutron rocket is now set for 2026, instead of this year. The company said more testing and qualification work was needed.<\/p>\n

Sir Peter Beck, the CEO of Rocket Lab, announced the shift in plans during the third quarter earnings call with investors on Nov. 10. He said that the company\u2019s goal is to get the rocket out to Launch Complex 3 at the Virginia Spaceport Authority\u2019s (VSA) Mid-Atlantic Regional Spaceport (MARS) within the first quarter of 2026 \u201cwith first launch thereafter.\u201d<\/p>\n

\u201cAs always, this is a rocket program that\u2019s been completed at a pace and a cost that nobody has achieved before and the financial and long-term impacts are insignificant to take a little bit more time to get it right,\u201d Beck told investors on the call.<\/p>\n

Without naming names, Beck said others have raced to the launch pad without being fully ready for launch and that would not be their approach. He emphasized that Rocket Lab\u2019s goal is to have a fully successful first flight and to make it to orbit without issue.<\/p>\n

\u201cYou won\u2019t see us minimizing some qualifier about us just clearing the pad and claiming success and whatnot,\u201d Beck said. \u201cAnd that means we don\u2019t want to learn something during Neutron\u2019s first flight that could be learned on the ground during the testing phase.<\/p>\n

\u201cAt the end of the day, Neutron will fly when we\u2019re very confident it\u2019s ready and we\u2019re not going to break the mold of the Rocket Lab magic.\u201d<\/p>\n

While the 141-foot-tall (43 m) two-stage rocket is designed to be reusable, part of a successful first flight of Neutron won\u2019t be proving reuse of the booster. Rocket Lab is still developing its 400-foot-long landing barge called \u2018Return on Investment\u2019, which Beck said should be ready to support Neutron\u2019s second launch.<\/p>\n

Beck said that the methane and liquid oxygen powered Archimedes engines, which will power the liftoff of Neutron with 1.5 million pounds of thrust, continue to go through validation and qualification. He said they\u2019re using two test stands at NASA\u2019s Stennis Space Center in Mississippi at a 20-7 rate: 20 hours a day, seven days a week.<\/p>\n

\u201cThe only way you can get through years of qualification that are always expected for an engine program is to squeeze years of hours into months,\u201d Beck said. \u201cAs you can imagine, no weekends or evenings are left on the table at the Stennis test facility.\u201d<\/p>\n

When asked by Michael Leshock of KeyBanc Capital Markets about how close they were to a finalized design of the Archimedes engine, Beck said the \u201cengine design\u2019s pretty stable at this point,\u201d adding that Rocket Lab had \u201cmet all the performance criteria.\u201d<\/p>\n

\u201cWith ascent there\u2019s one set of environments and with descent, there\u2019s an entirely new set of environments and much more challenging environments because your propellant will warm and lower pressures,\u201d Beck said. \u201cThe vast, vast majority of all the components for Flight 1 engines are either complete or in some kind of form of build.<\/p>\n

\u201cWe\u2019re iterating on the engine for sure, but the production machine is stood up and ready to support.\u201d<\/p>\n
