Blue Origin Charts a New Path Back to Flight for New Glenn After Pad Explosion
After late-May explosion destroyed a New Glenn being readied to fly NASA's Blue Moon 'Endurance' lander, Blue Origin says it won't rebuild the ruined pad as-is — instead adopting a hybrid horizontal-vertical integration concept at LC-36A and aiming to fly again in 2026.
