On Monday, April 20, 2026, Blue Origin CEO Dave Limp provided an initial technical assessment of the “off-nominal” orbital delivery during the company’s third New Glenn mission (NG-3).
While the flight achieved a significant milestone by successfully reusing a first-stage booster for the first time (read SatNews), a thrust anomaly in the upper stage resulted in the loss of AST SpaceMobile’s BlueBird 7 satellite.
Technical Failure Analysis: The GS2 Burn
The mission, which launched on Sunday, April 19, from Cape Canaveral, performed nominally through booster separation and recovery. However, data indicates that the issue occurred during the second burn of the second stage (GS2). One of the two BE-3U hydrogen-fueled engines failed to produce sufficient thrust to reach the target insertion orbit.
As a result of the underperformance, the BlueBird 7 satellite was deployed at an altitude significantly lower than planned. AST SpaceMobile confirmed that while the satellite successfully separated and initialized its power systems, its onboard thrusters do not have the propellant capacity to raise the spacecraft to a sustainable operational orbit. Consequently, the satellite will be de-orbited to prevent the creation of long-term space debris.
Strategic Impact on AST SpaceMobile
The loss of BlueBird 7 is a setback for AST SpaceMobile’s timeline for a nationwide direct-to-cell commercial service. BlueBird 7 was the second of the company’s larger Block 2 architecture, following the successful deployment of BlueBird 6 in February.
Despite the mission failure, AST SpaceMobile representatives stated that the cost of the satellite is expected to be recovered under the company’s insurance policy. The firm has reiterated its target of having 45 satellites in orbit by the end of 2026, with BlueBird satellites 8 through 10 currently scheduled for shipment in approximately 30 days.
Executive Perspective: Blue Origin Leadership
“Early data suggest that on our second GS2 burn, one of the BE-3U engines didn’t produce sufficient thrust to reach our target orbit. While we are pleased with the nominal booster recovery, we clearly didn’t deliver the mission our customer wanted, and our team expects.” — Dave Limp, CEO of Blue Origin.
Regulatory Status and Next Steps
The Federal Aviation Administration (FAA) has officially classified the event as a “mishap” and has grounded the New Glenn vehicle pending a formal investigation. Blue Origin will lead the investigation with FAA oversight to identify the root cause of the engine underperformance.
The investigation must receive FAA approval before New Glenn can return to flight. This grounding may impact the launch manifest for the remainder of 2026, though industry analysts point to the rapid 15-day return-to-flight timeline achieved by SpaceX following similar upper-stage anomalies in 2024 as a potential benchmark for recovery.
