Blue Origin says it still does not know the cause of the May 28 explosion of its New Glenn rocket, even as it prepares for a return to flight. In a blog post described by multiple outlets, CEO Dave Limp says early analysis points to the aft section of the rocket’s first stage, while the company continues to examine data from multiple camera angles and sensors. The investigation remains ongoing, with Blue Origin indicating that more time and evidence are needed before determining what failed.

Separately, Spaceflight Now reports that Blue Origin is outlining logistics and process changes for future New Glenn launches. As part of its response, the company says it is moving to a hybrid horizontal-to-vertical integration approach for its rockets going forward. This reflects efforts to adjust how the vehicles are assembled and prepared, alongside the still-unresolved failure investigation.

Across the reports, Blue Origin maintains its intention to resume New Glenn launches later in the year, though the underlying cause of the explosion has not yet been publicly confirmed.
