The article compares SpaceX's Raptor and Blue Origin's BE-4 rocket engines, highlighting differences in thrust, fuel, efficiency, and real-world application, with Raptor being more advanced in chamber pressure and specific impulse, while BE-4 is more commercially available and has seen successful actual launches.
Blue Origin, the space company founded by Jeff Bezos, experienced a setback when its BE-4 rocket engine exploded during testing in June. The explosion destroyed the engine and damaged the test stand infrastructure. The engine was expected to be used on United Launch Alliance's second Vulcan rocket launch. Blue Origin is currently assessing the root cause of the issue and has informed its customer of the incident. The failure may further delay the first Vulcan launch, which was already rescheduled for the fourth quarter of this year. Blue Origin needs to resolve the engine issue to support both Vulcan and its own New Glenn rocket, which is under development.
