NASA Readies Historic Stand for New Glenn’s 400,000-Pound Upper-Stage Test
NASA and Blue Origin agreed in July 2026 to prepare the historic B-2 test stand at Stennis Space Center in Mississippi for hot-fire testing of New Glenn’s second stage, with the campaign targeted to begin this fall. Under an annex to a reimbursable Space Act Agreement, NASA will supply engineering personnel, equipment, building services, workspace and propulsion-test expertise for a stage powered by two engines producing a combined rated 400,000 pounds of vacuum thrust, according to the agency’s July 24 announcement.
The agreement does not mean testing has started, nor does it establish that New Glenn has completed qualification for Artemis work. It puts NASA infrastructure and experience behind the next phase of Blue Origin’s upper-stage test program as the company prepares for lunar-launch assignments supporting Artemis missions planned for 2027 and beyond.
A full-stage test position with Apollo roots
The B-2 position is designed to test complete rocket stages rather than individual engines. Built during the 1960s, the stand previously supported Saturn V stage testing for Apollo. NASA later used it for the Space Launch System core stage’s Green Run series before the Artemis I flight.
That history is relevant for more than symbolism. A full-stage hot fire evaluates an assembled propulsion system under operating conditions while ground instrumentation captures its performance. In broad engineering terms, this allows teams to assess the interaction of engines, propellant systems and stage hardware in a controlled facility before relying on the same assembly in flight.
NASA said its personnel will help design, build and install the parts needed to prepare B-2 for New Glenn. The agency will also provide dedicated workspace and lessons learned from earlier propulsion campaigns. The required modifications have not been detailed, so it is not yet possible to assess their scope, complexity or effect on the fall target.
Hydrogen propulsion defines the test requirement
New Glenn’s second stage uses two BE-3 engines burning liquid oxygen and liquid hydrogen. NASA rates each engine at 200,000 pounds of thrust in vacuum, producing the headline combined figure of 400,000 pounds based on the stated per-engine rating.
Testing a hydrogen-fueled stage requires infrastructure suited to cryogenic propellants and the operating demands of the complete propulsion system. The agreement’s practical value is that Blue Origin can add an established federal test location while drawing on a workforce with experience conducting large propulsion tests. Blue Origin has described the B-Test Complex as an additional testbed intended to expand its second-stage hot-fire capacity and separate that work from launch-pad operations at Launch Complex 36.
That added capacity can matter as a launch program moves toward more demanding government missions. Dedicated stage testing and launch operations compete for facilities, people and schedule margin when they share a site. A separate test stand does not eliminate development risk, but it can give the program another place to conduct planned ground work without making every test activity dependent on access to the launch complex.
Artemis relevance comes with open questions
NASA said New Glenn will launch missions intended to land on the Moon and connected the Stennis campaign to Artemis missions from 2027 onward. It separately described Artemis III as a multi-launch campaign in which four astronauts will test Orion rendezvous and docking with commercial human landing systems from Blue Origin and SpaceX in low Earth orbit.
Those plans increase the importance of propulsion readiness, but the present agreement is for test support not a declaration of mission readiness. NASA and Blue Origin have not disclosed the reimbursable agreement’s value, the planned number or duration of hot fires, detailed campaign objectives, acceptance criteria or a firm starting date. Because the arrangement is reimbursable, Blue Origin is expected to pay for NASA’s covered support, but no amount has been released.
The next visible milestone is therefore facility preparation, followed by the targeted start of testing in fall 2026. Until the stand work is complete and results are reported, the strongest conclusion is a measured one: NASA is converting proven stage-test infrastructure into additional capacity for New Glenn’s hydrogen upper stage. That gives Blue Origin a technically relevant path to gather ground-test data for future lunar work, while leaving qualification status, cost and schedule performance unresolved.
