New Glenn Rocket Completes Integrated Launch Vehicle Hotfire
Last Checkout Before First Launch of Blue Origin's Orbital Rocket
New Glenn successfully completed an integrated launch vehicle hotfire test late last week, the final major milestone on the road to first flight. NG-1 will carry a Blue Ring Pathfinder as its first manifested payload and will launch from Launch Complex 36 in Cape Canaveral, FL, according to Blue Origin.
“This is a monumental milestone and a glimpse of what’s just around the corner for New Glenn’s first launch.”

The seven-engine hotfire lasted 24 seconds and marked the first time the entire flight vehicle was operated as an integrated system. The multi-day test campaign leading up to the hotfire included numerous inert functional and tanking tests. The integrated launch vehicle included the first and second stages of the NG-1 flight vehicle, and a payload test article comprised of manufacturing test demonstrator fairings, a high-capacity fixed adapter flight unit, and a 45,000 lb payload mass simulator.
One of the primary goals of the test campaign was to demonstrate day-of-launch operations in our NG-1 test configuration. Additionally, the team conducted several tests to validate vehicle and ground systems in the fully integrated, on-pad configuration. This data will be utilized to finalize day-of-launch timelines, confirm expected performance, and correlate our models to real-world test data.
“This is a monumental milestone and a glimpse of what’s just around the corner for New Glenn’s first launch,” said Jarrett Jones, SVP, New Glenn. “Today’s success proves that our rigorous approach to testing–combined with our incredible tooling and design engineering–is working as intended.”
The tanking test included a full run-through of the terminal count sequence, testing the hand-off authority to and from the flight computer, and collecting fluid validation data. The first stage (GS1) tanks were filled and pressed with liquefied natural gas (LNG) and liquid oxygen (LOX), and the second stage (GS2) with liquid hydrogen and liquid oxygen–both to representative NG-1 set points.
The formal NG-1 Wet Dress Rehearsal demonstrated the final launch procedures leading into the hotfire engine run. All seven engines performed nominally, firing for 24 seconds, including at 100% thrust for 13 seconds. The test also demonstrated New Glenn’s autogenous pressurization system, which self-generates gases to pressurize GS1’s propellant tanks.
This test campaign captured a number of firsts for the New Glenn launch system, including the first seven-engine operations, the first integrated GS1-GS2 tanking demonstration, the first LNG/LOX fill for GS1, as well as first chilled helium operations for GS2.
The campaign met all objectives and now has completed the final major test prior to launch.
Blue Origin has several New Glenn vehicles in production and a full customer manifest. Customers include NASA, Amazon's Project Kuiper, AST SpaceMobile, several telecommunications providers, and a mix of U.S. government customers. Blue Origin is certifying New Glenn with the U.S. Space Force for the National Security Space Launch (NSSL) program to meet emerging national security objectives.
