Investigation Clearance Granted
Following an issue encountered during its third flight on April 19th, Blue Origin has successfully concluded its comprehensive investigation into the New
Glenn rocket's launch anomaly. The company announced the completion of this review, which has been met with approval from the Federal Aviation Administration (FAA). This crucial milestone means that launches of the New Glenn vehicle can now resume, marking a significant step forward for the ambitious rocket program after a period of technical scrutiny. The anomaly occurred during the second burn phase of the rocket's upper stage, known as GS2, which ultimately prevented the intended deployment of the BlueBird 7 satellite for AST SpaceMobile into its correct orbit. The clearance from the FAA signifies that the agency is satisfied with the thoroughness of Blue Origin's analysis and the proposed solutions.
Root Cause Identified
The primary cause behind the New Glenn NG-3 mission's upper stage problem has been pinpointed. During the crucial second burn of the GS2 stage, an unexpected thermal condition arose, leading to one of the BE-3U engines not reaching its full thrust capability. This deviation prevented the rocket from achieving its designated orbital trajectory. The FAA's independent assessment corroborated this, identifying a cryogenic leak as the direct culprit. This leak resulted in the freezing of a hydraulic line, which subsequently caused a thrust anomaly during the engine's operation. This detailed understanding of the failure's origin is paramount for implementing effective preventative measures and ensuring the reliability of future missions. The satellite customer, AST SpaceMobile, has indicated understanding, noting that such upper-stage issues are not uncommon in the early stages of rocket development.
Corrective Actions Implemented
In response to the identified root cause, Blue Origin has proactively developed and is implementing a series of nine corrective actions designed to prevent any recurrence of this specific anomaly. While the exact details of these measures have not been publicly disclosed, the FAA has confirmed its role in verifying the successful implementation of all these corrective steps. This verification process will be a mandatory prerequisite before the next New Glenn mission, designated NG-4, can proceed to launch. The company is reportedly already making preparations for this next flight, with its chief executive hinting at an upcoming integrated hotfire test. This rigorous approach to addressing technical challenges underscores a commitment to robust engineering and operational safety, building confidence for both the company and its partners as they move forward with their launch cadence.
